Cable for automobiles

Abstract

The invention discloses a cable for automobiles. The materials of the sheath of the cable include the following components in parts by weight: 30 to 50 parts of nitrile rubber; 5 to 10 parts of 2, 4-toluene diisocyanate dimer; 20 to 30 parts of terminal isocyanate based polyurethane prepolymer, 1 to 2 parts of dibuty phthalate; 04 to 0.8 part of dioctyl phthalate; 0.2 to 0.6 part of bis(2-ethylhexyl) terephthalate; 30 to 40 parts of carbon black; 10 to 14 of calcium carbonate; 10 to 20 part of kaolin; 5 to 12 parts of modified mica ; 5 to 8 parts of liquid epoxy resin; 2 to 4 parts of polyethylene vinyl esters; 1 to 3 parts of tetrafluoroethylene; 0.5 to 1 part of antioxidant 1010; 0.8 to 1.2 of antioxidant 1035; 1 to 2 parts of antioxidant 1076; and 2 to 3 parts of vulcanization system. The cable for the automobiles of the invention has advantages of excellent elasticity and toughness, high heat resistance, and will not malfunction under intensive bending.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable for automobiles. Background technique [0002] With the vigorous development of the automobile industry, high-performance cables for automobiles have been put on the agenda. Due to the large increase in electronic devices in automobiles, the requirements for the size of electronic devices in automobiles are getting higher. On the one hand, the cables are required to be as flexible as possible for easy placement. On the other hand, cables for automobiles sometimes need to be immersed in liquids. Most of these immersion liquids are flammable. If the cables break down, they will burst and cause fire hazards. At present, polyester elastomers are mostly used to prepare sheath materials. , but it is easy to decompose in a hot and humid environment, so that the heat resistance, solution resistance, and fire resistance performance cannot meet the requirements, and cannot meet the ...

[0002] With the vigorous development of the automobile industry, high-performance cables for automobiles have been put on the agenda. Due to the large increase in electronic devices in automobiles, the requirements for the size of electronic devices in automobiles are getting higher. On the one hand, the cables are required to be as flexible as possible for easy placement. On the other hand, cables for automobiles sometimes need to be immersed in liquids. Most of these immersion liquids are flammable. If the cables fail, burst, and cause fire hazards, polyester elastomers are mostly used to prepare sheath materials. , but it is easy to decompose in a hot and humid environment, so that the heat resistance, solution resistance, and fire resistance performance cannot meet the requirements, and cannot meet the needs in some extreme environments. How to prepare a kind of elasticity, toughness, heat resistance, solution resistance, fire resistance performance Excellent cables that are difficult to use even under strong bending have become a technical problem that needs to be solved at present
