Abstract

The invention discloses a high-toughness low-odor scratch-resistant polypropylene composition. The high-toughness low-odor scratch-resistant polypropylene composition comprises the following components in part by weight: 40 to 80 parts of polypropylene resin, 10 to 30 parts of inorganic filler, 0.5 to 10 parts of scratch-resistant agent, 2 to 15 parts of thermoplastic elastomer and 0.1 to 1 part of antioxidant. All the components are mixed uniformly and then subjected to double-screw extrusion and granulation. The high-toughness low-odor scratch-resistant polypropylene composition has excellent comprehensive performance such as low odor, high toughness, high dimensional stability, durable and high scratch resistance, no precipitation and the like, simple and continuous production flow, high production efficiency and stable product quality. The basic performance of the base material is maintained; scratch resistance and toughness of the product are improved; and the using range of the product is enlarged. The composition can replace materials such as acrylonitrile butadiene styrene (ABS) and the like well and has a good application prospect.
