Abstract

The invention discloses an automotive interior decorative plate prepared by utilizing a waste polypropylene material. The preparation method comprises the steps: cleaning and crushing a waste polypropylene material and then adding an adjuvant such as resin and rare earth oxide, fully mixing, heating and compression molding to obtain a composite plate for automotive interior decoration. The prepared plate has the advantages of strong anti-acid resistance capacity, strong organic solvent resistance capacity, high temperature resistance, and uneasiness in oxidation and aging.

Description

technical field [0001] The invention relates to the field of automobile interior decoration, in particular to an automobile interior decoration plate prepared from waste polypropylene materials. Background technique [0002] With the rapid development of the polymer material industry, plastic processing has formed a department with complete categories and varieties in just a few decades, which plays an important role in the development of the national economy. It is worth noting that due to the increasing use of plastics, waste plastics have caused serious environmental pollution, but at the same time they contain important renewable resources. Recycled plastics are different forms of plastics that exist in terms of their recycling value at the end of their useful life. Almost all thermoplastics have recycling value. However, compared with the rapid development of the domestic plastics industry, the recycling and utilization of domestic waste plastics lag far behind the dev...
