The present invention relates to a composition for producing a fiber-reinforced polymer composite for tensile wire of overhead power transmission line and a method for producing a fiber-reinforced polymer composite for tension wire in overhead power transmission line using the same, and more particularly, to a thermosetting resin such as an epoxy resin in a polymer resin composition. A composition for producing a fiber-reinforced polymer composite for tensile wire of a overhead transmission line that can minimize the deflection of the overhead transmission line by improving the high-temperature characteristics by appropriately blending additives such as a curing agent and an accelerator, and a fiber-reinforced polymer composite for tension wire of a overhead transmission line using the same It relates to a manufacturing method.

Conventional overhead transmission lines have been used aluminum conductor steel reinforced (ACSR) cables incorporating aluminum or aluminum alloy, which is a conductor layer, on the outer periphery of the strand to bear tension. However, since the coefficient of thermal expansion of the stranded wire increases in proportion to the temperature, the ACSR cable as described above causes the stranded wire to sag due to an increase in temperature accompanied by an increase in power transmission amount (sag phenomenon: sag), and the entire overhead line falls down. Will fall. In preparation for this phenomenon, it is necessary to increase the number of pylons installed in order to construct sufficiently high pylons or to close the gaps between them. However, such an alternative may not be an inherent solution to the problem, and may cause other problems in terms of economy and the like.

According to US Pat. No. 6,796,365, a composite for manufacturing wires in which aluminum is added as a fiber reinforced composite resin has been proposed. However, the thermal expansion coefficient of the composite has a problem that the deflection phenomenon is larger than that of the polymer composite when applied to a processed transmission. It is pointed out. According to International Patent Publication No. WO 03/091008, it is proposed to manufacture a fiber-reinforced composite with a single wire having a large diameter without associating it, but the physical properties such as tensile strength do not satisfy the requirements, Due to the complexity of the process, there is a problem in compatibility, and it is pointed out that it is not easy to store or transport because the fiber reinforced composite is manufactured in a single wire having a large diameter without being associated.

Therefore, in the related fields, continuous research has been made on how to prevent or minimize sagging by improving the physical properties of the overhead transmission line, but the development of the composition for manufacturing the overhead transmission line itself is easy in the related industry. It will be apparent that this cannot be achieved, but the necessity of solving such a problem is recognized, and efforts have been made to solve various problems previously known, and the present invention has been devised under such a technical background.

The technical problem to be achieved by the present invention on the basis of the above-mentioned conventional problems, to solve the problem that the transmission line sag occurs, but to develop a new material that does not change the other properties, It is an object of the present invention to provide a composition for producing a fiber-reinforced polymer composite for tensile wire of a processed transmission line and a method for producing a fiber-reinforced polymer composite for tensile wire of a processed transmission line using the same.

In order to achieve the technical problem to be achieved by the present invention, one of the compositions for producing a fiber-reinforced polymer composite for tensile wire of the overhead transmission line provided in the present invention, the epoxy resin is a thermosetting resin; Hardening | curing agents which are liquid as an acid anhydride type or an amine compound; Accelerators which are imidazole compounds or borontrifluoride ethylamine compounds; Mold release agents that are zinc stearate; And a filler which is nanoclay or short glass fiber.

Hereinafter, specific examples will be described in order to help the understanding of the present invention, and in the following case, with reference to the drawings will be described in more detail. However, embodiments according to the present invention can be modified in many different forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.

The composition for producing a fiber-reinforced polymer composite for an overhead transmission line provided in the present invention includes a thermosetting resin, a curing agent, an accelerator, a mold releasing agent, and a filler.

It is preferable that an epoxy resin is used for the said thermosetting resin.

At this time, the epoxy resin selected as the thermosetting resin is contained in the content of 25 to 400 parts by weight based on the weight of the epoxy resin of the di glycidyl ether bisphenol A type and the epoxy resin of the di glycidyl ether bisphenol A type. It is preferable that it is a mixture of 3 types of epoxy resins which consist of a functional group epoxy resin and the di glycidyl ether bisphenol F type epoxy resin contained in content of 5-25 weight part with respect to the weight of the said di glycidyl ether bisphenol A type epoxy resin. . In this case, the polyfunctional epoxy resin is more preferably any one or three or more polyfunctional epoxy resin selected from glycidyl amine and novolac.

When ester resin is chosen as said thermosetting resin, it is preferable that cyanate resin is used independently. In the case where polyimide-based resin is used as the thermosetting resin, an aromatic heterocyclic polyimide resin or a bismalide type polyimide resin is preferably used. Particularly, the aromatic heterocyclic polyimide resin is easy to mold. It is preferred to use a form derived from bisphenol A in order to ensure that this is the case.

The epoxy resin of the di glycidyl ether bisphenol A type may be represented by the following formula (1).

The polyfunctional epoxy resin may be represented by the following formula (2).

The di glycidyl ether bisphenol F-type epoxy resin may be represented by the following formula (3).

The said hardening | curing agent is preferable if it is a liquid as an acid anhydride type or an amine compound.

In this case, the acid anhydride-based compound selected as the curing agent is selected from methyl tetrahydro phthalic anhydride (MTHPA), tetra hydro phthalic anhydride (THPA), hexa hydro phthalic anhydride (HHPA), and Nadic methyl anhydride (NMA) As one or a mixture of two or more, it is preferable to include in an amount of 60 to 160 parts by weight based on the weight of the epoxy resin. Regarding the numerical range of the content of the acid anhydride-based compound, if it falls below the lower limit, the heat resistance is lowered due to unreacted epoxy formation during curing, and if the upper limit is exceeded, the remaining curing agent reacts with the epoxy and acts as an impurity. It is not preferable to lower heat resistance and physical properties.

The amine compound selected as the curing agent is a cyclo aliphatic polyamine-based material or an aliphatic amine-based material, and is preferably included in an amount of 15 to 60 parts by weight based on the weight of the epoxy resin. The setting of the numerical range for the use amount of the amine compound is made for the same reason as the setting of the numerical range for the content of the acid anhydride compound.

The cyclo aliphatic polyamine-based material among the amine compounds selected as the curing agent is any one selected from menteinadiamine (MDA) and isoprondiamine (IPDA), and the aliphatic among the amine compounds selected as the curing agent. The amine substance is more preferably any one selected from diaminodiphenylsulfone (DDS) and diaminodiphenylmentane (DDM).

The accelerator is preferably an imidazole compound when an acid anhydride compound is used as the curing agent, and a boron trifluoride ethylamine compound is preferably used when an amine compound is used as the curing agent.

When the imidazole compound is selected as the accelerator, it is preferable to be included in an amount of 1 to 5 parts by weight based on the weight of the epoxy resin. Regarding the amount of the imidazole compound used and the numerical range for the compound, if the lower limit is not reached, it is difficult to expect the promotion of curing for the purpose of addition. If the upper limit is exceeded, an increase in the proportional effect to the amount of addition is not expressed. Rather, it is not preferable because it acts as an impurity to lower the physical properties of the product due to over addition.

When the boron trifluoride ethylamine-based compound is selected as the accelerator, it is preferable to include 2 to 10 parts by weight based on the weight of the epoxy resin. The setting of the numerical value range with respect to the use content of the said boron trifluoride ethylamine type compound is made for the reason similar to the setting of the numerical range with respect to the content of the imidazole compound.

The release agent is preferably zinc stearate. On the other hand, zinc stearate selected as the release agent (Zinc stearate) is preferably included in an amount of 1 to 5 parts by weight based on the weight of the thermosetting resin. The release agent used in this way reduces the friction between the product and the forming die, thereby improving workability. Regarding the numerical range of the content of the release agent, if it falls below the lower limit, it is not preferable because the purpose of the addition cannot be achieved. If the upper limit is exceeded, an increase in proportional effect to the addition amount is not achieved, but rather over-added. Due to the impurity to lower the physical properties of the product is not preferred.

The filler is preferably nanoclay or short glass fiber.

When the nanoclay is selected as the filler, it is preferably included in an amount of 1 to 5 parts by weight based on the weight of the thermosetting resin, and more preferably, the nanoclay is in a whisker or flake phase. Regarding the numerical range of the use amount of the nanoclay as the filler, if the lower limit is not reached, the purpose of the addition cannot be achieved, and if the upper limit is exceeded, an increase in proportional effect to the addition amount is not achieved. It is not preferable because it acts as an impurity that lowers the physical properties of the product due to over addition.

When short glass fiber is selected as the filler, the short glass fiber is preferably contained in an amount of 5 to 30 parts by weight based on the weight of the thermosetting resin, and the short glass fiber is more preferably free of boron. With respect to the numerical range for the use content of the short glass fiber as the filler, if the lower limit is not reached, the purpose of the addition cannot be achieved, and if the upper limit is exceeded, the increase in proportion to the addition amount is not achieved. Rather, it is not preferable because it acts as an impurity to lower the physical properties of the product due to over addition.

In order to achieve the technical problem to be achieved by the present invention, the fiber-reinforced polymer composite for overhead transmission line provided in the present invention is manufactured by sequentially performing the following steps (S1) to (S6).

First, any one material selected from (S21) titanate, silane, and zirconate is selected as a solute, and an isopropyl alcohol (IPA) solution of 800 to 1,000 times the weight of the selected solute is selected as a solvent. The solute is dissolved in a solvent to prepare a coupling solution. Subsequently, while maintaining the temperature of the prepared coupling solution (S22) at 70 to 80 ° C, the prepared high strength fiber is completely immersed in the coupling solution. Finally, (S23) the coupling solution in which the high strength fiber is immersed is stirred for 30 minutes to 2 hours. By performing the steps of (S21) to (S23), the surface treatment for the high strength fiber is completed. When surface treatment is performed on the high strength fibers as described above, the interfacial bonding force between the high strength fibers and the subsequently thermosetting resin is improved.

(S3) drying in vacuum oven

After surface treatment by the wet method using the coupling solution, it is sufficiently and completely dried in a vacuum oven of 100 ° C. or higher, and care is then taken for storage so that moisture does not come in direct contact.

(S4) Impregnation in composition

Each component of the composition for preparing a fiber-reinforced polymer composite for overhead transmission line according to the present invention prepared as described above is mixed and maintained at a temperature of 40 to 60 ° C. in order to lower the viscosity, and the composition is subjected to a mechanical stirrer. Mix uniformly using At this time, the stirring speed is maintained at 100RPM or more, by using a vacuum pump during stirring to remove the moisture and bubbles generated during the stirring inside the thermosetting resin. The prepared high strength fiber is impregnated with the thus prepared composition.

(S5) composition curing

After the impregnation is made, heat and pressure or ultrasonic waves are applied to cure the penetrated composition in the high strength fibers.

(S6) cooling

The hardened fiber reinforced polymer composite is rapidly cooled to complete the final product.

The process of the above manufacturing steps (S1) to (S6) can be made using one continuous system device, for example, a device for producing a wire rod made of a high strength fiber reinforced polymer composite, which is slightly modified in a device known in the art. It is obvious that it can be used immediately as it is.

On the other hand, it should be understood that the above-described embodiments (1 to 3) have not been given examples in which all cases of the claims are considered, but have been disclosed by selectively adopting some examples which are considered to be the most desirable.

Using the compositions according to the above Examples (1 to 3) and Comparative Examples (1 to 8), high tensile wire specimens of each processed transmission line were manufactured, and the room temperature characteristics, the high temperature characteristics, the aging characteristics, and the bending characteristics were determined by the following methods. Measured by

In order to evaluate the room temperature characteristics, tensile strength (kgf / mm 2), elongation (%) and modulus of elasticity (kgf / mm 2) were measured for each specimen while maintaining the tensile speed at 5 mm / min. Indicated.

As can be seen through Table 2, Example 3 is added to the short glass fiber, showing a higher tensile strength than other examples. Comparative Examples 3, 4 and 6 are used as a high-strength fiber that is not surface-treated, showing a tendency to lower the tensile strength compared to other comparative examples, which is not preferable, from which the properties of the product depending on the surface treatment of high-strength fibers It can be inferred that the difference is due. In general, in consideration of the fact that tensile strength of 200kgf / mm2 or more is required in consideration of the temporary tension of the overhead transmission line and the thermal decomposition and aging characteristics of the polymer material due to long-term thermal exposure, all of the Examples 1 to 3 exceed the reference values. It can be confirmed that the effects of the present invention can be clearly confirmed.

After evaluating the high temperature characteristics for 20 minutes at a given temperature for each specimen, the tensile strength (kgf / mm2) and tensile residual percentage (%) at each given temperature were maintained while maintaining a tensile rate of 5 mm / min. The measurement is shown in Table 3 below.

In view of the high temperature tensile strength of 170 kgf / mm2 or more at 180 ° C. in consideration of long time exposure at high temperatures of the overhead transmission line, Comparative Examples 3, 5, and 6 have polyfunctional resin contents (Examples 1 to 3). Compared with Example 1, Comparative Example 3 shows a relatively low tensile strength due to the lack of heat resistance. It can be seen that it is not preferable.

In order to evaluate the aging characteristics, the specimens were left at a given temperature for 1,000 hours, and then the tensile strength (kgf / mm 2) and the tensile residual percentage (%) were measured at room temperature while maintaining the tensile velocity at 5 mm / min. It is shown in Table 4 below.

Aging tensile strength is a physical property for confirming the properties of a polymer material that is pyrolyzed when exposed to high temperature for a long time. In view of the fact that more than 180 kgf / mm2 is required for 1,000 hours of aging at 180 ° C, Comparative Examples 3 and 4 are not surface treated. When exposed to high temperature for a long time due to the use of high strength fibers exhibits low tensile strength by weakening the interfacial bond between the high strength fibers and epoxy, Comparative Examples 5 and 6 show low heat resistance due to not applying a polyfunctional epoxy resin, Comparative Examples 7 and 8 show low tensile strength due to the use of polypropylene and unsaturated polyester, which are thermoplastic resins having low heat resistance, and thus are not preferable.

Four-point bending test was used for each specimen to evaluate the flexural characteristics, and the flexural strength (kgf / mm2) and flexural modulus (kgf / mm2) were measured while maintaining the measurement speed at 1.3 mm / min. 5 is shown.

Flexural strength is required to minimize the bending of overhead transmission lines due to wind, rain and snow applied to steel towers. Flexural modulus is a physical property that confirms flexibility for winding and storage on bobbins. In this case, it is known to have desirable physical properties. Comparative Examples 3, 4, and 6 exhibited low flexural strength by using high-strength fibers without surface treatment, and Comparative Examples 1 and 2 exhibited high flexural modulus without addition of diglycidyl bisphenol F. It is not desirable because of its hard characteristics.

According to the results of measuring the physical properties for each of the specimens shown in Tables 2 to 5 according to Examples (1 to 3) compared to the case according to the Comparative Examples (1 to 8), room temperature characteristics, high temperature characteristics, aging characteristics and It can be seen that the flexural characteristics were all excellent.
