Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a type of reactivity in which a rod-shaped molded body composed mainly of a reactive resin as a main component and a rod-shaped molded body composed mainly of a curing agent are arranged in parallel with a slight gap therebetween . those related to the putty coated body.
[0002]
[Prior art]
<Reactive putty material of the first type>
As a reactive putty material, a rod-shaped first molded body composed mainly of a reactive resin as a main component and a rod-shaped second molded body composed mainly of a curing agent are separately packaged. (A first type of reactive putty material). In order to facilitate handling in the manufacturing process of each molded body and to prevent the molded body after packaging from sticking to the packaging material, a release sheet is stuck on both sides of each molded body to form a covering body. Is normal.
[0003]
When this first type of reactive putty material is used, a necessary amount is cut from each of the first molded body and the second molded body, and both are kneaded with fingers, and then used as a putty material. For home work, it is often the case that both molded bodies have the same shape so that almost equal amount of mixing can be achieved even if there is some error when mixing with the reference amount.
[0004]
<Second type of reactive putty>
Further, as another type of reactive putty material (referred to as a second type of reactive putty material), a rod-shaped first molded body composed of a main ingredient mainly composed of a reactive resin, and a curing agent as a main ingredient. The rod-shaped second molded body to be placed is arranged in parallel with a slight distance (with a gap) between them, and the releasable sheets are provided on both sides of the parallel-formed body of the first molded body and the second molded body. It is also known that the film is pasted and further packaged with a packaging material. The reason why the first molded body and the second molded body are slightly separated is that curing proceeds at the contact interface when the two are in contact with each other. FIG. 6 is a cross-sectional view in the width direction schematically showing an example of the conventional reactive putty material of the second type. (1) is the first molded body, (2) is the second molded body, 3), (3) is the releasable sheet, and (4) is the packaging material indicated by the one-dot chain line.
[0005]
This second type of reactive putty material is discharged from an extruder for forming the first molded body and the second molded body, and the release sheet is attached to both sides of the parallel disposed body after discharge. Furthermore, a series of steps up to packaging can be automated, which is preferable in terms of productivity. In addition , if the parallel-arranged body is cut in the width direction when used, each piece of the first molded body and the second molded body can be obtained in a predetermined weight ratio. It becomes a mixing ratio of the curing agent, which is preferable in terms of usability as compared with the first type reactive putty material.
[0006]
[Problems to be solved by the invention]
However, in the second type of reactive putty material, when a curing agent that has a proper curing rate is used as a curing agent that is a main component of the second molded body, such a curing agent generally has a slight volatilization. Therefore, during the distribution and storage period of the product, the volatile gas affects the reactive resin that is the main component of the first molded body and faces the second molded body of the first molded body in a relatively short period of time. If the end face or side edge portion or the peripheral portion on the side to be cured is hardened and the storage period is extended, it will be unavoidable that problems will occur in actual use.
[0007]
Therefore, a devise to use a low volatility curing agent (for example, a polyaminoamide-based curing agent when the main agent of the first molded body is a bisphenol A type epoxy resin) as a curing agent for the second molded body has been made. In use, the curing rate after mixing tends to be excessively slow, and if the distribution and storage period of the product is prolonged due to the reactive volatile gas remaining in a trace amount in the curing agent, the first molded body still remains. It is not possible to effectively prevent the end surface or side edge portion on the side facing the second molded body or its peripheral portion from being cured.
[0008]
In addition, a perforated wrapping material is used as a wrapping material for wrapping the entire second type reactive putty material made up of the first molded body and the second molded body, and a gaseous curing agent evaporating from the second molded body is used. Although the device has been devised to escape to the exterior as soon as possible, it is still not possible to sufficiently prevent the end surface or side edge portion of the first molded body facing the second molded body or the peripheral portion thereof from being cured.
[0009]
In the present invention, the first molded body and the second molded body are arranged in parallel with a small distance (with a gap) like the above-mentioned second type reactive putty material. In the case where a release sheet is attached to both sides of a product and the whole is further packaged, the end surface or side edge portion of the first molded product facing the second molded product during the distribution and storage period of the product or the periphery thereof It is an object of the present invention to provide a reactive putty material covering in which the curing reaction of a part is difficult to proceed and a volatile curing agent having a relatively high reaction rate can be blended or used. To do.
[0010]
[Means for Solving the Problems]
The reactive putty covering of the present invention is
The second molded body of rod-like first molded body of the rod-shaped made of base resin to the reactive resin as a main component and a curing agent (1) as a main component and (2) are arranged in parallel with a gap, and, In a reactive putty material covering having a structure in which release sheets (3) and (3) are coated on both upper and lower surfaces of a parallel arrangement of the first molded body (1) and the second molded body (2). ,

[0019]
The first molded body (1) and the second molded body (2) have the same thickness (cross-sectional area). Often to be able to achieve. However, for example, the first molded body (1) can be made thicker and the second molded body (2) can be made thinner. This is because the first molded body (1) and the second molded body (2) are arranged in parallel as described later, and are used by cutting in the width direction of the parallel arranged body. This is because a constant mixing ratio can always be obtained.
[0020]
The first molded body (1) and the second molded body (2) are arranged in parallel with a gap . The gap (opposing end surface as described below (1a), and the gap in the state before the deformation when it is deformed into a shape such as a pointed shape in the practice of the shape steps (2a)) can be set appropriately However, about 0.5 to 3 times, especially about 1 to 2.5 times the thickness of these molded products (1) and (2) is suitable.
[0021]
Releasable sheets (3) and (3) are coated on the upper and lower surfaces of the parallel arrangement of the first molded body (1) and the second molded body (2). Here, as the releasable sheet (3), (3), for example, a sheet obtained by treating a thin film sheet such as polyolefin film, polyester film, paper, polyethylene laminated paper or the like with a release agent such as a silicone release agent; Is a sheet having releasability; a sheet formed by internally adding a release agent to a resin; and the like.
[0022]
Here, the groove-shaped gap between the first molded body (1) and the second molded body (2) arranged in parallel is defined as a gap (G), the first molded body (1), and the second molded body (2 ) Opposite end faces (1a), (2a), and the opposite end faces (1a), (2a) are called opposite end faces (1b), (2b), respectively. To.
[0023]
Now, in the present invention, both the above-mentioned releasable sheets (3), (3) are opposed to each other via the above-mentioned gap (G), and these both releasable sheets (3 ), (3) also covers the opposing end faces (1a), (2a). This is a feature point that is a point of the present invention.
[0024]
In the end view in the width direction of the parallel arrangement body at the final product stage, the shapes of the opposed end faces (1a) and (2a) of the first molded body (1) and the second molded body (2) are, for example, 1, FIG. 3, FIG. 4, and FIG. Incidentally, the conventional product has a shape as shown in FIG .

[0026]
<Method for producing reactive putty covering >
The reactive putty material covering of the present invention can be produced by any method as long as it has the above-described configuration, but industrially, it is particularly preferably produced by the following two methods.
[0027]
(Production method / Part 1)
One of the industrially advantageous methods for producing a reactive putty covering is:
(A) Each of a composition comprising a main component mainly composed of a reactive resin and a composition comprising a curing agent as a main component is discharged from an extruder to produce a rod-shaped first molded body (1) and a rod-shaped first A process of forming a parallel arrangement body in which the two molded bodies (2) are arranged in parallel with a gap ;
(B) The process of covering the upper and lower surfaces of the parallel arrangement body with the release sheet (3), (3) at the time of the previous process or following the previous process,

[0032]
By using a perforated packaging material as the packaging material (4), it is also preferable to release volatile gases such as amines that may be volatilized from the second molded body (2) to the outside of the bag.
[0033]
(Production method / Part 2)
Another method for producing an industrially advantageous reactive putty coating is:
(A) Each of a composition comprising a main component mainly composed of a reactive resin and a composition comprising a curing agent as a main component is discharged from an extruder to produce a rod-shaped first molded body (1) and a rod-shaped first A process of forming a parallel arrangement body in which the two molded bodies (2) are arranged in parallel with a gap ;

In such a deformed state, the parallel-arranged bodies are covered, and thus the deformed release sheet (3) opposes the first molded body (1) and the second molded body (2) facing each other. End face (1a), (2a) is also covered,
(D) The process of cutting the whole into a predetermined length in the width direction and packaging with packaging material (4),
It is a method of implementing.
[0034]
As an example of the shape when the releasable sheet (3) is deformed to match the groove-shaped gap (G), the upper part of the releasable sheet (3) is an area along the sheet center line. Concave, “V”, “Le” and other shapes are available. For the lower release sheet (3), the areas along the center line of the sheet are “convex”, “Λ”, “inverted” The shape etc. which were made are raised.
[0035]
