Abstract

The invention provides a polypropylene composite material for an automobile internal ornament, a preparation method thereof and an automobile internal ornament. The polypropylene composite material for the automobile internal ornament comprises 40-60 parts by weight of polypropylene resin, 0-30 parts by weight of filler, 1-5 parts by weight of compatibilizer, 5-15 parts by weight of toughening agent, 1-5 parts by weight of scratch-resistant agent, 1-5 parts by weight of odor adsorption agent, 5-15 parts by weight of anti-static agent, 0.1-0.5 part by weight of antioxidant and 0.3-1 part by weight of lubricating agent. Therefore, the polypropylene composite material which has the characteristics of low odor, scratch-resistant surface, low surface resistivity and excellent mechanical properties and is used for the automobile internal ornament can be obtained.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polypropylene composite material used for automobile interior decoration, a preparation method thereof and an interior decoration part. Background technique [0002] Polypropylene (PP) is one of the five general-purpose plastics. Due to its low specific gravity, good performance, easy processing and low price, it is widely used in automotive interior and exterior parts. However, due to the low hardness of polypropylene raw materials, it is easy to be scratched during use as an automotive interior part, and the surface of the part is white, which affects the appearance. With the continuous enhancement of environmental protection and health awareness, the requirements for air quality in the car Also keep improving. Therefore, the development and use of polypropylene materials that meet the requirements of low odor, scratch resistance and antistatic at the same time has...
