Abstract

The invention discloses a method for preparing automobile damping plastic. The method comprises the following steps: mixing polycarbonate, an acrylonitrile-butadiene-styrene copolymer, polystyrene, a calcium carbonate complex, sepiolite powder, lanthanum oxide, kieselguhr and fumed silica to obtain a first material; putting epoxy soybean oil, disproportionated rosin, vinyl tri(beta-methoxyethyoxyl)silane, an antioxidant 168, an anti-aging agent DFC-34, stearic acid and acetic anhydride into the first material, mixing, heating, degumming, leaving to stand at the room temperature, further adding tert-butyl hydroperoxide and dibutyltin dilaurate, performing heating stirring, extruding, performing injection molding, and cooling, thereby obtaining the automobile damping plastic. The automobile damping plastic prepared with the method is very excellent in damping property and very high in impact resistance, the impact strength and the toughness under a high-temperature condition can be ensured, and the damping problem of a material can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a method for preparing shock-absorbing plastics for automobiles. Background technique [0002] The current energy shortage and environmental pressure are increasing, and the sustainable development of the automobile industry is facing challenges. As an effective means of energy saving, automobile lightweight technology has become one of the important research topics in the development of the automobile industry. At present, in the way of realizing the lightweight of automobiles, the materials can be used to reduce the weight of automobiles through material substitution. In terms of alternative materials, reinforced plastic polymer lightweight materials can be used to achieve the purpose of reducing density and increasing strength. But at present, the shock absorption and impact resistance of plastic materials can not meet the demand, and urgently need to be solved. Contents of...
