る。[Prior Art 1] In general, flame-retardant electric wires are produced by a method of highly filling a water-containing inorganic compound or a method of using a halogen compound. The latter method is achieved, for example, by mixing flammable polyethylene with a chlorinated or brominated organic flame retardant and antimony trioxide. Further, by mixing antimony trioxide with chlorinated polyethylene, flame retardation can be achieved relatively easily. However, chlorinated polyethylene has lower heat resistance than polyethylene. Therefore, antioxidants are added to electric wire insulators for the purpose of imparting the necessary heat resistance. Furthermore, for the purpose of improving heat resistance, for example, as described in Japanese Patent Publication No. 1-19818,
There is a chlorinated polyethylene composition for the purpose of organic peroxide crosslinking to which a coprecipitate of basic lead salt and silica gel is added.

Further, in Japanese Patent Publication No. 42-9010, it is exemplified that an antioxidant and a lead compound are mixed into chlorinated polyethylene.

If the epoxy compound exceeds 3 parts by weight or the lead compound exceeds 1/2 part by weight, the insulation resistance will decrease and must be avoided. If used within the range prescribed in this invention, it is possible to suppress deterioration of electrical properties and improve heat resistance. Epoxy compounds include epoxidized soybean oil, epoxidized linseed oil, or Epicote 828.

The sample was coated with a film of 2 mm and crosslinked by electron beam irradiation of 15 Mrad. The obtained wire insulation has flame retardancy (
UL standard vertical flame retardancy) and heat aging resistance (temperature 160°
The tensile strength and residual elongation of C were investigated. As a result, while the tensile strength did not show much of a degree of deterioration, the elongation was significant and reflected the degree of deterioration, so the heat aging resistance was evaluated based on the residual elongation. In addition, the initial growth is 200
% or less, the residual elongation rate is high and it is not preferable as a 6-wire insulator. Table 1 shows the evaluation results. It has very high heat resistance. Other properties are good.
