Plastic bumper material for automobiles and method for preparing plastic bumper material

Abstract

The invention discloses a plastic bumper material for automobiles. The plastic bumper material is made of, by weight, 52-54 parts of polycarbonate, 30-45 parts of polytetrafluoroethylene, 8-10 parts of polymethyl methacrylate, 12-16 parts of carbon fibers, 9-15 parts of polyurethane, 12-14 parts of sodium bicarbonate, 4-8 parts of urea, 12-14 parts of paratoluenesulfonic acid, 8-10 parts of fatty alcohol polyoxyethylene ether sulfate, 3-4 parts of poly-butantetraol, 11-15 parts of p-toluenesulfonhydrazide, 2-4 parts of acetone, 10-14 parts of dichlorofluoroethane, 22-24 parts of polybutadiene rubber latex, 16-20 parts of butylbenzene latex, 4-8 parts of borax, 8-12 parts of epoxidized soybean oil, 7-9 parts of magnesium hydroxide, 24-25 parts of ammonium polyphosphate, 13-18 parts of ethylene-vinyl acetate copolymers, 7-11 parts of nanometer titanium dioxide and 6-10 parts of polyvinyl butyral. The plastic bumper material for the automobiles has the advantages that the plastic bumper material is high in structural strength and excellent in elasticity and can have cushioning functions, accordingly, injury to pedestrians can be reduced, and sound-insulation effects can be realized.

Description

technical field [0001] The invention relates to an automobile plastic bumper material and a preparation method thereof. Background technique [0002] The existing automobile bumper is a safety device for absorbing and slowing down external impact force and protecting the front and rear parts of the vehicle body. Many years ago, the front and rear bumpers of automobiles were stamped out of steel plates into channel steel, riveted or welded together with the frame longitudinal beams, and there was a large gap with the body, which looked very unattractive. With the development of the automobile industry and the extensive application of engineering plastics in the automobile industry, automobile bumpers, as an important safety device, are also on the road of innovation. In addition to maintaining the original protection function, the front and rear bumpers of today's cars also pursue harmony and unity with the car body shape, and pursue their own lightweight. The front and rea...
