Abstract

The invention relates to a composite material, in particular to a high-temperature-resistant TPEE / ETFE composite material and a preparation method thereof. The composite material comprises the following raw materials in parts by weight: 50 to 80 parts of PEE, 5 to 20 parts of ETFE, 5 to 10 parts of a composite flame retardant, 0.1 to 0.5 part of an antioxidant, 0.1 to 1 part of a lubricant and 5 to 10 parts of a compatilizer. The TPEE / ETFE composite material disclosed by the invention not only has relatively low dielectric constant and dielectric loss, but also has good high-temperature resistance and flame retardance, so that the requirements of wires and cables of automobiles are met.

Description

technical field [0001] The invention relates to a composite material, in particular to a high temperature resistant TPEE / ETFE composite material and a preparation method thereof. Background technique [0002] In many occasions, wires and cables are required to have good flexibility. At this time, rubber is often used as the sheath of wires and cables. Although rubber has excellent flexibility, wear resistance and weather resistance, it requires high investment, and many manufacturers do not have it. Ability to process rubber cables. Thus developed TPEE cable material thermoplastic polyester elastomer (TPEE) is a block copolymer containing polyester hard segment and polyether soft segment. Because thermoplastic polyester elastomers have the advantages of excellent elasticity of rubber and ease of processing, impact resistance, oil resistance, and chemical solvent corrosion resistance of thermoplastics. The existing TPEE has different temperature resistance grades depending ...
