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.
