Abstract

The invention discloses an automobile wire harness protection sleeve. The automobile wire harness protection sleeve is prepared from the following components in parts by weight: 112-120 parts of ethylene-propylene-diene monomer, 25-32 parts of isoprene rubber, 25-32 parts of acrylonitrile-styrene copolymer, 5-7 parts of thiophene, 12-19 parts of N,N'-(4,4'-methylenediphenyl)dimaleimide, 5-9 partsof polyamide, 4-8 parts of polycarbonate, 8-16 parts of dioctyl phthalate, 9-16 parts of polyoxyethylene lauryl ether, 10-15 parts of barium stearate, 4-8 parts of flexibility auxiliary and 7-11 partsof a wear resistant auxiliary. A wire harness protection sleeve material is excellent in mechanical performance, the elongation at break of the wire harness protection sleeve material can be up to 87.6%, the tensile strength can reach 18.4 MPa, the wire harness protection sleeve material has good elasticity and tenacity, meanwhile, the volume resistivity of the wire harness protection sleeve material is greatly improved, and the wire harness protection sleeve material has good insulativity.

Description

technical field [0001] The invention relates to the technical field of wiring harnesses, in particular to a protective cover for automotive wiring harnesses. Background technique [0002] With the rapid development of my country's economy, the application environment of automotive wiring harnesses is becoming more and more diverse and more stringent. Many of them need to meet the characteristics of high and low temperature resistance, flame retardancy and oil resistance. At present, most of the research is focused on the wire harness itself, and relatively little research is done on its protective sheath material. The protective sheath material is in direct contact with the environment. It not only needs to have good insulation properties, but also has good mechanical properties and some special properties, which play an important role in protecting cable materials and extending the life of wire harness materials. At present, the most widely used protective cover materials ...
