Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of manufacturing a fluid injection insulator,

The present invention relates to a method for manufacturing a heat insulating material using a fluid and a heat insulating material produced by the method.

Insulation is a material that reduces the heat transfer between one side and the other to maintain a temperature difference between the inside and outside of a specific space or object. Therefore, the insulation is used for various purposes such as a building, a vinyl house or a warehouse, as well as a variety of devices requiring insulation and the storage of a specific object.

The heat insulating material has a closed structure, and there is a heat insulating material formed by injecting air into the inside of the heat insulating material. In order to form such a closed structure, two heat insulating sheets are bonded, and in the past, a heat sealing method has been mainly used for bonding the heat insulating sheets.

The heat sealing method is a method in which a high temperature is applied to a sheet to be joined to bond it, and is widely used in producing envelopes for documents or other sealing products. If a heat sealing method is used to produce such an inflatable insulating material, a large amount of cost is required to produce a large-sized insulating material.

In order for the heat sealing method to be applied to the inflatable insulation, a heat sealing operation must be performed on all the interfaces of the insulation sheet after first preparing the insulation sheet. However, in such a method, since the heat insulating member must be cut to a desired size and then bonded to each interface, a complicated process is required and the cost is increased.

In the case of a large air-inflated insulation used in a plastic house or a warehouse, a considerable amount of cost is required when the insulation is produced by such a heat sealing method. However, a more economical manufacturing method is required for producing a tube- .

On the other hand, the air injected into the sheet may be excellent in heat insulation performance, but there is a limit in the aspect of adapting to the environment to which the heat insulating material is applied. It would be useful if there is insulation that can adapt to the season and the environment by using the space to keep warm or cold depending on the situation.

In particular, greenhouses often collapse because they can not sustain the snow load in the winter months with heavy snowfall. Since a vinyl house is not designed to bear a large load in terms of its characteristics, a method of manufacturing a heat insulating material capable of protecting a vinyl house against a situation where a snow load becomes large as a relatively special case is required.

The present invention proposes a method of manufacturing a heat insulating material capable of economically producing a large-sized fluid injection insulator and a heat insulating material produced by the method.

According to one aspect of the present invention, an adhesive is applied to a first heat insulating sheet by a roller device so that a portion of a plurality of first flow path portions communicating in a first direction with portions not coated with an adhesive in the first heat insulating sheet, Applying an adhesive to form a part of a second flow path communicating between the flow paths; In the second heat insulating sheet having the size corresponding to the first heat insulating sheet and the first heat insulating sheet, the second heat insulating sheet is bonded to the first heat insulating sheet so that the portion not bonded by the adhesive forms the first flow path portion and the second flow path portion Thereby forming an insulating sheet composite; And inserting a fluid into the first flow path portion and the second flow path portion of the heat insulating sheet composite, wherein the roller device includes a body portion and a plurality of application portions protruding from the body portion and configured to apply an adhesive, And the inner coating portions of the plurality of application portions except for the outermost coating portions of the body portion are discontinuously protruded along the outer periphery of the main body portion.

The inner application portions can be arranged alternately so that at least one of the second flow paths can communicate only between two adjacent first flow paths of the plurality of first flow paths.

In one embodiment of the present invention, the inner application portions can be arranged such that at least one of the first flow path portions continuously communicates from the top to the bottom of the heat insulating sheet composite. In this case, the width of the first flow path portion may be smaller than the width of the second flow path portion communicating with the first flow path portion.

In another embodiment of the present invention, the inner application portions are disposed alternately so that at least one of the first flow path portions is not continuously communicated from the upper side to the lower side of the heat insulating sheet composite, and a plurality of first flow path portions are arranged along one straight line .

The width of the first flow path portion may be configured to be within 1.5 times the interval of the first flow path portion. At least one of the first heat insulating sheet and the second heat insulating sheet may be formed of an opaque material. When both the first and second heat insulating sheets are formed of a transparent material, the step of injecting the fluid may include the step of injecting a fluid containing a dye that prevents transmission of light of a specific wavelength.

The method of manufacturing the insulation may further include cutting the first insulating sheet to a predetermined size before or after the step of forming the insulating sheet composite. The method may further include the step of joining the transverse edges of the heat insulating sheet composite.

The joining of the transverse edges may be accomplished by at least one of adhesive bonding, heat sealing, and tape bonding methods.

The method for manufacturing a heat insulating material may further include forming a fluid inlet for injecting a fluid at a predetermined position on the insulating sheet composite and a fluid outlet for discharging the injected fluid.

The fluid injection port may be formed near the corner of the heat insulating sheet composite, and the fluid discharge port may be formed on the opposite side of the fluid injection port in the diagonal direction of the heat insulating sheet composite. The fluid inlet may be formed at one lateral edge of the heat insulating sheet composite and the fluid outlet may be formed at the other lateral edge of the heat insulating sheet composite and the step of joining the transverse edge of the heat insulating sheet composite may include forming the fluid inlet and / The predetermined position of the fluid outlet can be prevented from joining.

According to an aspect of the present invention, it is possible to produce a fluid injection type heat insulating material having a high productivity at low cost.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. Like reference numerals are used for like elements in describing each drawing.

The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be referred to as a second component, and similarly, the second component may also be referred to as a first component.

In the fluid injecting thermal insulating material manufactured by the manufacturing method according to an embodiment of the present invention, a grid-shaped flow path formed densely therein is formed, and a fluid such as air or water is injected into the flow path.

As the fluid is injected into the inside of the insulating material, by changing the state of the fluid, it is possible to change the effect of keeping or keeping the insulating material. For example, it is possible to increase the cooling effect by passing cold water through the inside of the thermal insulation material during the summer season, and to increase the thermal insulation effect by passing hot water having a relatively higher temperature inside the thermal insulation material during the winter season.

Particularly, it is possible to prevent the vinyl house from being collapsed by excessive snow load in the winter season by using the fluid injection insulator. That is, the snow loaded on the vinyl house can be frozen and adhered to the vinyl house itself due to the low temperature. If the hot water is passed through the inside of the heat insulating material, the hot water can melt the frozen part so that the loaded snow slips down .

Embodiments of the present invention relating to such a heat insulating material and for manufacturing the same will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flowchart showing an overall flow of a method for manufacturing a fluid injection insulator according to an embodiment of the present invention.

Referring to FIG. 1, first, a first heat insulating sheet 300 is prepared and an adhesive is applied to the first heat insulating sheet 300 (step S110). Here, the first heat insulating sheet 300 has a rectangular shape and may have a long shape so that the adhesive can be applied by rolling.

The first insulating sheet 300 may be made of any material capable of providing an insulating function.

According to one embodiment of the present invention, the heat-insulating sheet may be a flexible aluminum foil. For example, a heat insulating member can be realized with an aluminum material having a thin thickness such as an aluminum foil. The thin film aluminum can be processed by rolling aluminum or an aluminum alloy to a predetermined thickness.

According to another embodiment of the present invention, the insulating sheet may be embodied as a paper, nonwoven fabric or fabric product.

According to another embodiment of the present invention, the heat insulating sheet may be a flexible thin film synthetic resin. The synthetic resin may include a polyethylene (PE) film or a polyethylene terephthalate (PET) film. When a transparent synthetic resin material is used as the material, the first heat insulating sheet 300 can transmit light.

When the first heat insulating sheet is prepared, the adhesive can be applied to the first heat insulating sheet 300 by using the roller device 200. The roller according to an embodiment of the present invention is provided with a coating part to which an adhesive is applied, and the first heat insulating sheet 300 is applied to the coating part to apply an adhesive.

FIG. 2 is a plan view of a roller device 200 used for manufacturing a fluid injection insulator according to an embodiment of the present invention, and FIG. 3 is a cross-sectional view of a roller device 200 according to an embodiment of the present invention, Fig. 2 is a plan view conceptually showing a structure of a heat-insulating sheet made of a heat-

Referring to FIG. 2, a roller device 200 according to an embodiment of the present invention includes a main body 210 and a plurality of application portions 250a and 250b. The main body 210 has a cylindrical shape and is formed by protruding a plurality of application portions 250a and 250b from the main body 210. [ A plurality of application portions 250a and 250b are formed at predetermined intervals, and an adhesive is applied to each of the application portions 250a and 250b. As the adhesive, a waterproof adhesive can be used.

Adhesives should be selected that provide adequate bond strength, taking into account the amount of fluid injected and flowing and the fineness of the insulation.

The application portion 250a formed on the outermost side of the main body portion 210 among the plurality of application portions may have a continuous shape. On the other hand, the inner application parts 250b existing between the outermost application parts 250a among the plurality of application parts may have a discontinuous shape.

The first thermal insulation sheet 300 is held by the roller device 200 and the adhesive is applied to the first thermal insulation sheet 300 along the longitudinal direction by the adhesive applied to the application portions 250a and 250b through the rolling operation .

Referring to FIG. 3, when the adhesive is applied by the roller device 200, adhesive layers 350a and 350b are vertically formed on the first heat insulating sheet 300. FIG.

The adhesive layer 350a formed on both edges of the adhesive layer formed on the first heat insulating sheet 300 is also formed continuously since the application portions 250a on both edges of the application portions of the roller device 200 have a continuous shape .

Since the coated portion 250b between the two edge application portions 250a of the roller units 200 has a discontinuous shape, the adhesive agent formed on the region other than the edge region of the adhesive layer formed on the first thermal insulation sheet 300 The layer 350b is also discontinuously formed.

The portion where the adhesive layers 350a and 350b are not formed is a portion of the first flow path portion 310 extending in the longitudinal direction and a portion of the second flow path portion 320 extending between the first flow path portions 310 . That is, the first flow path portion 310 and the second flow path portion 320 are formed at a portion where the adhesive is not applied.

In the example of FIG. 3, the second flow path portion 320 is formed to be orthogonal to the first flow path portion 310, but the present invention is not limited thereto. The second flow path portion 320 may be formed in the first flow path portion 310 at different angles. Of course, considering the characteristics of the manufacturing method using the roller device 200 and the purpose of uniformly distributing the fluid to be injected into the heat insulating material, it is preferable that both the second flow path portions 320 are formed so as to be orthogonal to the first flow path portions 310 Can be advantageous. However, if the roller device 200 having a diameter sufficiently larger than that of the required size is used, the angle of the second flow path portion 320 may be designed to provide a more optimized flow path.

The protrusions 250b formed in the main body 210 of the roller device 200 may be arranged corresponding to the design of the first flow path portion 310 and the second flow path portion 320. [

A fluid is injected into the heat insulating material produced by the method for manufacturing a heat insulating material according to an embodiment of the present invention. A fluid inlet 505 and a fluid outlet 555 are formed in the heat insulating material and the first flow path 310 and the second flow path 320 form a flow path of the fluid to be injected into the heat insulating material.

The inner application portions 250b of the roller device 200 are configured such that the fluid injected into the heat insulating material flows from the fluid injection port 505 to the fluid discharge port 555 and is uniformly distributed over the heat insulating material, And the second flow path portion 320 are formed.

For example, the inner coated portions 250b may be alternately arranged so that the second flow path portion 320 in the first heat insulating sheet 300 can be formed to communicate only between two adjacent first flow path portions 310 There will be. Of course, the present invention is not limited thereto, and the second flow path portion 320 may communicate with the plurality of first flow path portions 310.

As shown in FIG. 3, the plurality of first flow path portions 310 may be formed to continuously communicate from the upper side to the lower side of the first heat insulating sheet 300. In the case where the fluid injection port 505 is formed on one side of the heat insulating material in the longitudinal direction and the fluid discharge port 555 is formed on the other side, the fluid can smoothly flow through the longitudinally continuous first flow path portion 310.

Of course, according to another embodiment of the present invention, at least one of the plurality of first flow path portions 310 may be formed so as not to continuously communicate from the upper side to the lower side of the first heat insulating sheet 300. In other words, a plurality of the first flow paths 310 may be disposed along one straight line. In the first flow path portion 310 located inside, even if the first flow path portion 310 does not continuously communicate vertically, It is possible to uniformly distribute the inside of the heat insulating material.

3, the width of the first flow path portion 310 is larger than the width of the second flow path portion 310 connected to the first flow path portion 310 when the first flow path portion 310 continuously communicates along the longitudinal direction, May be smaller than the width of the first electrode 320.

The width of the first flow path portion 310 on the first heat insulating sheet 300 is equal to the width of the second flow path portion 320 on the assumption that the first flow path portion 310 continuously communicates along the longitudinal direction , The flow in the first flow path portion 310 will have a relatively lower resistance as compared with the flow in the second flow path portion 320. Therefore, the width of the second flow path portion 320 can be set to be larger so that the fluid to be injected does not flow only along the first flow path portion 310 but can flow into the second flow path portion 320 more easily. Of course, in various embodiments, the widths of the first flow path portion 310 and the second flow path portion 320 can be variously set.

3, the width of each of the first flow paths 310 may be set in consideration of the interval between the adjacent two first flow paths 310. In addition, as shown in FIG. If the gap between adjacent two first flow paths 310 is too narrow compared to the width of each first flow path 310, the flow between the adjacent first flow paths 310 is reduced, 310 may be weakened because the flow through the second flow path 320 may be weakened because it does not meet the purpose of uniformly distributing the fluid inside the insulation.

In an embodiment of the present invention, the width of the first flow path portion 310 may be set to be within 1.5 times the interval between the first flow path portions 310. Of course, the present invention is not limited thereto, and the width of the first flow path portion 310 may be variously set.

When the adhesive is applied to the first heat insulating sheet 300 through the roller device 200, the second heat insulating sheet 400 is bonded to the first heat insulating sheet 300 to form the first passage portion 310 and the second passage portion 300, The heat insulating sheet composite 500 on which the heat insulating sheet 320 is formed can be formed (step S120).

The second heat insulating sheet 400 may have a size corresponding to the first heat insulating sheet 300. The first insulating sheet 300 and the second insulating sheet 400 may have substantially the same size but differ slightly depending on the design flow rates of the first flow path portion 310 and the second flow path portion 320 .

The first insulating sheet 300 and the second insulating sheet 400 may be bonded together with the adhesive applied thereto and only one of the first insulating sheet 300 and the second insulating sheet 400 may be bonded The bonding may be performed with the adhesive applied.

3, a portion corresponding to the x-axis is referred to as a vertical portion of the first heat insulating sheet, and a portion corresponding to the y-axis is referred to as a transverse portion. In Step S120, the longitudinal portion of the heat insulating sheet is bonded.

If both the first heat insulating sheet 300 and the second heat insulating sheet 400 are made of a transparent material, the heat insulating sheet composite 500 is also transparent and can transmit light. Transparent insulation can be utilized when it is advantageous for light to pass through, such as in a vinyl house or a building window.

On the other hand, depending on the situation, it is common to see cases where light transmission is required or not required. For example, in a window in a building, when the heating is needed during the winter season, the maximum inflow of solar radiation helps to reduce the heating load. However, when the air conditioner is required during the summer season, You can help.

The fluid injecting thermal insulating material according to an embodiment of the present invention may be configured such that both the first heat insulating sheet 300 and the second heat insulating sheet 400 are made of a transparent material and that the transparency of the flowing fluid can be changed. That is, in the winter season, ordinary water or hot water may be injected to allow sunlight to pass through the heat insulating material, and in the summer, a fluid containing a predetermined dye may be injected to partially block the sunlight. As the dyes for this purpose, commonly available coloring dyes may be used, but are not limited thereto. For example, a substance that transmits visible light but blocks or absorbs light of other wavelengths, that is, infrared light or ultraviolet light, may be contained in the fluid.

Then, the heat-insulating sheet composite 500 formed as described above can be cut (step S130).

Although FIG. 1 shows the step S130 of cutting the resulting heat-insulating sheet composite 500 after the step S120 of bonding the first and second heat-insulating sheets 300 and 400 to each other, In another embodiment of the present invention, the heat insulating sheet composite 500 may be formed by first cutting the first heat insulating sheet 300 and then joining the second heat insulating sheet 400 having a corresponding size. That is, the order of joining the first and second heat insulating sheets 300 and 400 to each other (S120) and cutting (S130) may be changed.

The cutting of the heat insulating sheet composite 500 or the first heat insulating sheet 300 can be performed by various methods and cutting is performed corresponding to a predetermined size.

4 is a perspective view conceptually showing an example of a structure in which longitudinal portions of the first heat insulating sheet and the second heat insulating sheet are joined.

Referring to FIG. 4, since the adhesive layers are vertically formed at predetermined intervals, the first heat insulating sheet 300 and the second heat insulating sheet 400, to which the longitudinal portions are bonded, are provided with a plurality of first flow path portions 310, A portion 320 is formed.

The first flow path portion 310 and the second flow path portion 320 may be filled with fluids such as cold air, warmth, cold water, hot water, etc., thereby improving the heat insulating performance of the heat insulating material.

In FIG. 4, the longitudinal edges of the first and second heat insulating sheets 300 and 400 are sealed, but the transverse edges are not yet sealed.

When the desired size of the heat insulating sheet composite 500 is obtained, the process of joining the transverse edges of the heat insulating sheet composite 500 is performed (step S140). The sealing of the inside of the heat insulating sheet composite 500 can be made by bonding the transverse portion.

The joining of the transverse portions of the heat-insulating sheet composite 500 can be performed in various ways. For example, the transverse portion of the heat insulating sheet composite 500 can be bonded using an adhesive.

According to another embodiment, the joining of the transverse portions of the heat insulating sheet composite 500 may be performed by a heat sealing method.

According to another embodiment, the transverse portion of the heat-insulating sheet composite 500 may be bonded using an adhesive means such as a tape.

By joining such a transverse portion, a fluid injection insulator according to an embodiment of the present invention is completed. However, if necessary, the transverse portion may not be joined. When the fluid inlet 505 and the fluid outlet 555 are formed at the lateral edge of the heat insulating sheet composite 500, only the corresponding portion may be not bonded.

5 is a plan view conceptually showing the interior of a fluid injection insulator according to an embodiment of the present invention.

Referring to FIG. 5, since the adhesive layer 350b in a portion of the heat insulating sheet composite 500 that is not the edge region is partially cut, a plurality of second flow paths 310 are formed between the adjacent first flow paths 310, A portion 320 is formed.

As described above, the fluid injected into the heat insulating material passes through the first flow path portion 310 and the second flow path portion 320, and is uniformly distributed throughout the heat insulating material.

The heat insulating sheet composite 500 may be provided with a fluid inlet 505 and a fluid outlet 555 (step S150).

According to an embodiment of the present invention, a heat insulating material may be used in a state in which the fluid is not discharged after the fluid is injected into the heat insulating composite 500. The fluid injected into the insulating material can perform the insulating function in a stopped state without flowing. An excellent heat insulating performance can be secured owing to the heat capacity of the fluid itself injected into the heat insulating material.

In this case, it is not always necessary to separately form the fluid inlet 505 and the fluid outlet 555, and one opening can perform the functions of both the fluid inlet 505 and the fluid outlet 555.

According to one embodiment of the present invention, fluid is continually injected into the insulative composite 500 through the fluid injection port 505, and the injected fluid can be continuously discharged through the fluid outlet 555. In particular, when snow is removed as an insulating material used for a plastic house, the temperature of the hot water will be lowered through heat transfer with the snow even if hot water is injected. In this case, hot water can be continuously supplied and replenished in the heat insulating material, and the water whose temperature has decreased while flowing through the inside of the heat insulating material can be discharged through the fluid outlet 555. Of course, the discharged water can be heated again and supplied to the fluid inlet 505.

Referring to FIG. 5, a fluid inlet 505 and a fluid outlet 555 for injecting fluid from the outside may be formed in a part of the edge joint of the fluid injection insulator. The fluid can be introduced into the interior of the heat insulating sheet composite 500 through the fluid inlet 505 and the fluid can be discharged through the fluid outlet 555.

The fluid injection port 505 may be formed on one side of the heat insulating material and the fluid discharge port 555 may be formed on the other side of the heat insulating material so that the fluid to be injected may be uniformly distributed throughout the heat insulating material. According to one embodiment of the present invention a fluid inlet 505 is formed near the corner of the thermal insulation sheet composite 500 and a fluid outlet 555 is formed in the diagonal direction of the thermal insulation sheet composite 500, And is formed on the opposite side. This makes it possible to prevent the injected fluid from circulating only in a part of the insulating material.

If the fluid inlet 505 and the fluid outlet 555 are formed in the transverse edge of the insulating sheet composite 500, the step of joining the transverse edges of the above-described heat insulating sheet composite 500 to the heat insulating sheet composite 500 The predetermined positions of the fluid inlet 505 and the fluid outlet 555 may not be joined.

Although the step S150 of forming the fluid inlet 505 and the fluid outlet 555 after the step S140 of joining the transverse edges of the insulating sheet composite 500 is shown in FIG. 1, The fluid inlet 505 and the fluid outlet 555 may be formed first and then the lateral edges of the heat-insulating sheet composite 500 may be joined. That is, the step S140 of joining the transverse edges of the heat insulating sheet composite 500 and the step S150 of forming the fluid inlet 505 and the fluid outlet 555 may be changed in the order.

Finally, fluid can be injected into the manufactured heat-insulating sheet composite 500 (step S160). As described above, the heat insulating material may be used without injecting and discharging the fluid, and if necessary, the fluid may be continuously injected while simultaneously discharging the fluid.

It will also be apparent to those skilled in the art that if the fluid injection port 505 is opened without air, the air can naturally enter and act as a heat insulator.

The fluid injection insulator manufactured by the manufacturing apparatus and method of the present invention can be effectively applied to a vinyl house. When the heat insulating material of the present invention is used in the form of a roll screen or installed in a ceiling or a wall of a vinyl house, a considerable amount of energy can be saved by cutting off the external cold and heat.

In addition, it may be used in the form of a roll screen or attached to a ceiling or a wall in a building such as a warehouse or a house.

Particularly, the fluid injection insulator manufactured according to some embodiments of the present invention can be adapted to the situation by changing the characteristics of fluid to be injected according to the environment and season in which it is used, thereby maximizing the effect of warming or cooling.

In addition, even if the insulation is produced in a large scale, it does not include a high cost process such as heat sealing, so that it can provide high productivity at low cost.

As described above, the present invention has been described with reference to particular embodiments, such as specific elements, and specific embodiments and drawings. However, it should be understood that the present invention is not limited to the above- And various modifications and changes may be made thereto by those skilled in the art to which the present invention pertains.
