ていた。Conventionally, synthetic rubbers such as butyl rubber, chloroprene rubber, and ethylene propylene rubber, and plastics such as polyethylene, crosslinked polyethylene, and polyvinyl chloride have been used for the insulators and sheath materials of electric wires and cables, depending on the purpose. Recently, thermoplastic elastomers, which have the properties of both rubber and plastic, have begun to be used as one such material. One such thermoplastic elastomer is styrene/ethylene-butylene-styrene copolymer? There is a composition based on Although this composition is thermoplastic, it has rubber-like elasticity, and its characteristics include high heat resistance and excellent flexibility, making it particularly suitable as a coating material for battery cable jackets and flexible cords. It is something. However, this styrene/ethylene-butylene/styrene copolymer 1t-
Main compositions have the drawbacks of poor oil resistance, cut-through, and heat deformation. Furthermore, there is a drawback that when a soldering iron comes into contact with a coating made of this composition, the coating melts, and it has been desired to eliminate these drawbacks.

We have developed a crosslinkable resin composition mainly composed of styrene-functional ethylene-butylene O-styrene co-polymerized resin, which has improved cut-through, thermal deformation, and solder resistance, and exhibits excellent properties when used as a coating material. The present invention will be described in detail below.

70 car it parts) On the other hand, when the amount of abrasion increases by 10-30 parts by weight, the composition becomes soft. Polypropylene is added to the mixture with oil. Polypropylene, normal isotactic polypropylene, modified polypropylene, etc. are used. This polypropylene imparts mechanical strength and heat resistance to the composition, and the amount added is 10 to 60 parts by weight based on 20 to 70 parts by weight of the copolymer, and the amount added is 70 parts by weight. If it is less than M part, the above addition effect is -Ir3
At 60 parts by weight, the composition becomes too hard, which is disadvantageous. The graph in the drawing illustrates the mixing ratio of a resin composition obtained by mixing this styrene/ethylene-butylene/styrene copolymer, oil, and polypropylene. The area surrounded by a hexagon inside the triangle representing the three components corresponds to the above-mentioned mixing ratio.

The copper damage preventive agent is added when the crosslinkable resin composition of the present invention is used for applications such as distribution lines, etc., and is commonly used as a triazole with the mark CI) A-/ (
Adeka, Argus Inc.), etc. are used. The amount of these stabilizers added is 7 to 7 to 100 quintillion broken parts of the resin composition.
If the amount is less than 20 parts by weight, the effect as a stabilizer will not be expressed, and if it exceeds 20 parts by weight, the physical properties of the crosslinkable resin composition will deteriorate, which is disadvantageous. In addition, the crosslinking aid is used when crosslinking the resin composition (single molecule crosslinking or thermal crosslinking).
It promotes crosslinking, and when carrying out electron beam crosslinking, sildTMP ()IJ methylolpropene trimethacrylate) etc. are used, and when carrying out heat crosslinking, DC
Organic peroxides such as P (dicumyl peroxide) are used. The amount of these crosslinking aids added is 7 to 20 parts by weight based on 700 parts by weight of the resin composition, and if it is less than 7 parts by weight, a sufficient crosslinking effect will not be obtained, and as the amount added increases, crosslinking will proceed. If the amount exceeds 20 parts by weight, crosslinking becomes excessive and the crosslinked resin composition becomes brittle, which is disadvantageous.

In addition, mechanical properties such as cut-through, thermal deformation, and solder resistance are also improved by crosslinking. In particular, regarding solder resistance, even if it comes into contact with a soldering iron, the resin content is gelatinized, so it will not melt.

Since it is made by adding stabilizer/-20 mm and cross-linking aid/-20 mm to S, it is easily cross-linked and gelled, and has excellent oil resistance, cut-through, and heat deformation. A crosslinked resin composition having good properties such as flexibility and tensile strength, and particularly excellent solder resistance can be obtained. Therefore, this crosslinkable resin composition can be suitably used not only for covering electric wires but also for shrink tubes, sheets, molded products, and the like.
