Problems solved by technology

[0004] However, the particularity of TPEE material makes it have the following disadvantages in processing and use: 1. TPEE has a low flame retardancy level, and the melt dripping situation is serious; 2. The melting point of polyester hard segment is high, and when the temperature is too high, Melt viscosity drops sharply, affecting production stability and product quality

Abstract

The invention discloses an irradiation cross-linked thermoplastic polyester elastomer cable material. The irradiation cross-linked thermoplastic polyester elastomer cable material comprises, by weight, 100 parts of thermoplastic polyester elastomer (TPEE), 15-40 parts of ethylene-vinyl acetate copolymer (EVA), 50-80 parts of a fire retardant, 0.3-2 parts of a lubricant, 0.3-3 parts of an antioxidant and 0.1-1 part of an ultraviolet light stabilizer. The invention also discloses a method for producing cables through using the cable material. Cable products produced by using the cable material have excellent room temperature and high temperature mechanical performances; irradiation crosslinking realizes good flame retardation performance on the premise of meeting environmental protection, and also realizes cost reduction; and the cable material can reach 125DEG C temperature resistance level, has excellent scratch and wear resistance, and can be widely used in the fields of automobile wires and high and low temperature resistant cables.

Description

technical field [0001] The invention relates to an elastomer cable material and a cable production method, in particular to a radiation crosslinked thermoplastic polyester elastomer cable material and a cable production method. Background technique [0002] With the advancement of science and technology and the improvement of living standards, the increasing popularity of motor vehicles has made the public pay more and more attention to driving safety, and the automotive wires of the engine and lamps are required to work stably in a narrow wiring space and high temperature environment.
