Abstract

The invention discloses a silicon-aluminum crosslinked alloy for electric automobile conductor insulating materials and a preparation method of a conductor covered thereby. The silicon-aluminum crosslinked alloy is prepared from, by weight, 45.0-50.0% of polyvinyl chloride resin, 4.0-5.0% of calcium carbonate, 5.0-6.0% of disilicon trioxide, 1.0-2.0% of antimony trioxide, 1.0-2.0% of calcium stearate, 0.5-1.0% of zinc stearate, 0.5-1.0% of polyethylene wax, 0.5-1.0% of 1,2-bis(3,5-di-tert-butyl-4-hydroxyl-phenylpropionic acid)hydrazine, 10.0-12.0% of polyester ether, 20.0-25.0% of phosphite 2-ethylhexanoate, 1.0-2.0% of 2-methyl ethyl ester, 0.5-1.0% of fatty acid glyceride, 0.5-1.0% of 4,4'-bis(a,a'-dimethylbenzyl)aniline, 2.0-3.0% of trihydroxy methylpropane trimethyl acid ester, 2.0-3.0% of chlorinated polyethylene and 0.5-1.0% of methyl styrene. According to the silicon-aluminum crosslinked alloy, the expansion rate of the conductor in oil or acid and alkali solution is less than 2%, and the conductor can be twisted by 360 degrees at random and is conveniently bent and fitted in an automobile.

Description

technical field [0001] The invention relates to an insulating material, in particular to a silicon-aluminum cross-linked alloy and a preparation method for a coated wire used in an electric vehicle, which can satisfy oil resistance, corrosion resistance, small bending radius and easy installation. Background technique [0002] When an electric vehicle is in use, its DC high-voltage wires will swell and deform due to the presence of gasoline, lubricating oil or other acid-base substances in the car body environment. Under the permissible conditions, the expansion rate of the insulating material of the DC high-voltage wire should be less than 15%, which is a safe state. But the insulating material of existing wire, its expansion rate is all about 40%. Although some insulating materials can meet the requirements of oil resistance expansion rate, such as Teflon. But the material is too hard to meet the bending requirements in the car body to facilitate installation. This is b...
