Manufacturing method of electric wires / cables and electric wires / cables

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an electric wire / cable having a good appearance, heat resistance, high wear resistance and high strength. SOLUTION: At least two components of a resin composition (A) containing a polyolefin-based resin, an organic peroxide, a silane coupling agent, and an inorganic filler, and a silanol condensation catalyst resin composition (B) are used. An electric wire / cable having a step (α) of forming a melt-mixed mixture (C) around a conductor and / or an optical fiber, and a step (β) of contacting the molded product with water to bridge the mixture. In the production method, in 100% by mass of the resin component in the mixture (C), an unsaturated carboxylic acid-modified polyolefin resin, an ethylene- (meth) alkyl acid copolymer, and an ethylene- (meth) alkyl acid alkyl- (meth) alkyl The total content of the acid copolymer is 20 to 60% by mass, and the amount of metal hydrate is 20 to 300 parts by mass with respect to 100 parts by mass of the resin component in the mixture (C).
