Abstract

The invention relates to a low-odor scratch-resistant high-rigidity polypropylene composition and a preparation method thereof. The low-odor scratch-resistant high-rigidity polypropylene composition comprises the following components in part by weight: 60 to 90 parts of polypropylene, 10 to 20 parts of talcpowder, 0.1 to 20 parts of nano scratch-resistant agent, 0.5 to 3.0 parts of lubricating agent, 1.0 to 3.0 parts of antioxidant and 0.5 to 3.0 parts of calcium stearate. The product prepared by the method is high in surface scratch resistance, low in cost, low in odor, high in rigidity, high in flowability and impact-resistant, and is typically applied to production of dashboard products.

Description

technical field [0001] The invention belongs to the technical field of polymer material processing, and relates to a polypropylene composite material and a method thereof. Background technique [0002] Compared with engineering plastics, polypropylene raw materials are rich in sources, cheap in price, good in comprehensive performance, widely used, low in density, translucent, good in surface gloss, and good in heat resistance. Toughness, filling, reinforcement and alloy modification, obviously improve the performance to meet the special requirements of different fields. Therefore, it is increasingly used in automobiles and other fields. However, the scratch resistance of the modified polypropylene material is significantly reduced, but the scratch resistance of the material is a key performance of automotive interior applications such as instrument panels, consoles and door panel skins. Scratch resistance is one of the important properties of automotive interior parts, du...
