High-strength material for vehicles

Abstract

The invention discloses a high-strength material for vehicles, wherein the high-strength material comprises, by weight, 20-30 parts of PP, 15-25 parts of PS, 35-45 parts of ABS, 15-20 parts of PVC, 2-30 parts of poly-4-methyl-1-pentene, 14-26 parts of active calcium, 18-29 parts of stearic acid, 20-35 parts of lithopone, 25-30 parts of carbon black, 25-29 parts of modified wollastonite, 15-20 parts of polypropylene, 25-36 parts of thermoplastic polyurethane, 11-25 parts of high-strength carbon fiber, 25-30 parts of highly-elastic rubber, 1-3 parts of manganese, 1-8 parts of nickel, and 1-7 parts of phosphorus. According to the present invention, the high-strength material has good mechanical property, can provide elastic buffering effect during the impact on the vehicle, and can be used for vehicle bumpers, vehicle shells and the like.

Description

technical field [0001] The invention relates to a high-strength material for automobiles. Background technique [0002] There are many accidents in automobiles now, and the parts where automobiles often collide are bumpers and automobile bodies. At present, the main materials used are mostly polypropylene. The disadvantage is that the mechanical properties are poor, and its anti-collision performance cannot meet the ideal requirements. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a high-strength material for automobiles. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: A high-strength material for automobiles, characterized in that it includes the following parts by weight: PP20-30 parts, PS15-25 parts, ABS35-45 parts, PVC15- 20 parts, 2-30 parts of poly-4-methyl-1-pentene, 14-26 parts of active calcium, 18-29 parts of stearic acid, 20-35 parts of li...
