Abstract

The invention discloses a polypropylene material for automobile interior trim parts, and is characterized in that the polypropylene material is prepared from the following raw materials in parts by weight: 100-120 parts of isotactic polypropylene, 30-34 parts of a talcum powder, 12-15 parts of a ferroferric oxide powder, 5-6 parts of 2-ethylhexyl diphenyl phosphate, 12-15 parts of polyvinyl alcohol, 12-15 parts of metallocene linear low density polyethylene, 2-3 parts of dilauryl thiodipropionate, 3-4 parts of lignocellulose, 20-23 parts of SBS, and 7-9 parts of an auxiliary agent. The polypropylene material is relatively balanced in rigidity and toughness, has good scratch resistance, low cost and excellent comprehensive performance, can be widely applied in middle and high grade automobile interior and exterior trim parts with natural color and other colors.

Description

technical field [0001] The invention relates to a composite material for automobile interior decoration, in particular to a polypropylene material for automobile interior decoration and a preparation method thereof. Background technique [0002] Isotactic polypropylene (PP) has the advantages of low density, high cost performance, excellent heat resistance, rigidity, chemical corrosion resistance, easy processing and recycling, etc., making it widely used in automobiles and becoming a The largest and fastest growing variety of plastics. However, PP materials have poor heat resistance, low rigidity, low impact toughness, and low surface hardness compared with other materials, especially after adding talc powder, the scratch resistance is poor. These defects seriously restrict the application of isotactic polypropylene in the automotive field. Therefore, it is of great significance to improve the surface scratch resistance of PP materials.
