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.
