Abstract

The invention discloses heat-insulating anti-freezing electric vehicle battery shell material and relates to the technical field of manufacture of electric vehicles; the heat-insulating anti-freezing electric vehicle battery shell material is prepared from, by weight, 10-15 parts of bismaleimide resin, 10-15 parts of polyvinyl chloride paste resin, 10-15 parts of polyethylene glycol terephthalate, 5-10 parts of plastic drink bottle cap reclaimed particles, 5-10 parts of powdery nitrile rubber, 3-6 parts of terpene resin, 3-6 parts of polyoxyethylene, 2-4 parts of modified asbestos wool, 2-4 parts of sepiolite fiber, 1-2 parts of a weatherable aid, 1-2 parts of ethoxylated trimethylolpropane triacrylate, 0.5-1 part of N,N'-4,4'-diphenylmethane-bismaleimide, and 0.5-1 part of barium metaborate. The heat-insulating anti-freezing electric vehicle battery shell material has excellent heat-insulating and anti-freezing effects, can prevent a battery from being damaged by high temperature or low temperature, and enables a battery to charge and discharge normally even at high and low temperatures so that the service life of the battery is prolonged.

Description

[0001] Technical field: [0002] The invention relates to the technical field of electric vehicle manufacturing, in particular to a heat-insulating and anti-freezing type electric vehicle battery shell material and a preparation method thereof. [0003] Background technique: [0004] Electric vehicles, namely electric vehicles, are an environmentally friendly travel tool. A vehicle that uses a battery as an energy source to convert electrical energy into mechanical energy motion through controllers, motors and other components to control the current and change speed. Batteries are an important component of electric vehicles. In order to extend their service life, protective measures must be taken in summer and winter. On the one hand, it is necessary to prevent high-temperature exposure to electric vehicles. Exposure to the sun is strictly prohibited. An excessively high temperature environment will increase the internal pressure of the battery and force the battery pressure limitin...
