Flame-and wear-resisting resin compositions

摘要

A flame- and wear-resistant resin composition is prepared for use as a coating material and applied to electrical cables for automobile. The resin composition comprises a polymeric material consisting of a propylene-ethylene block copolymer and an ethylene-vinyl acetate copolymer, and a metal hydroxide. The polymeric material includes the propylene-ethylene copolymer in a proportion ranging from 90 to 45 % by weight with respect to the weight of the polymeric material, while the ethylene-vinyl acetate copolymer in a proportion ranging from 10 to 55 % by weight. The resin composition further includes the metal hydroxide ranging from 30 to 300 parts by weight, relative to 100 parts by weight of the polymeric material. In this resin composition, flame-resisting agents are properly dispersed, so that, even if its amount is increased, the coating material prepared therefrom maintains a high mechanical strength and wear resistance.
