Abstract

The invention discloses a preparation method for an automobile instrument board with high impact strength. The preparation method comprises the following steps of crushing quartz sand, then adding rosin modified phenolic resin, carrying out heating and stirring, continuously adding epoxidized soybean oil modified phenolic resin and carrying out heating and stirring so as to obtain a quartz sand compound; mixing the quartz sand compound, zirconium oxide microspheres, sepiolite powder, calcined kaolin, asphalt particles, sodium lignin sulfonate and cocamidopropyl betaine and carrying out heatingand stirring so as to obtain premix b; and mixing ABS resin and polypropylene, carrying out heating and stirring, then adding the premix b, dicumyl peroxide, 1,3-bis[3-(tert-butylperoxy)propyl]benzene and a titanate coupling agent, carrying out heating and stirring, heating a mixture to a molten state, carrying out extrusion and carrying out hot-press forming so as to obtain the automobile instrument board with high impact strength. The preparation method for the automobile instrument board with high impact strength has the advantages of being environment-friendly in process and less in pollution, and the obtained automobile instrument board is high in structural strength, high in impact strength, good in low-temperature brittleness and good in anti-aging effect.

Description

technical field [0001] The invention relates to the technical field of automobile instrument panels, in particular to a method for preparing an automobile instrument panel with high impact resistance. Background technique [0002] The dashboard is one of the most important parts of a car's body, located directly in front of the driver. Dashboards can be divided into hard plastic dashboards, blister dashboards and semi-rigid foam soft dashboards according to comfort. The dashboard body is made of hard plastic dashboards by injection molding because of its advantages of simple process and low investment. It is widely used, especially in low-end cars. However, at present, the plastic material used for the car dashboard body has a technical problem of low impact strength, which affects the aesthetics and use of the car interior, and needs to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the prese...
