Abstract

The invention discloses a low-temperature impact-resistant polypropylene composition, and a preparation method and an application thereof as a decoration in an automobile. The polypropylene composition comprises the following components in percentage by weight: 40-79.8% of polypropylene resin, 15-35% of mineral filler, 5-30% of toughener, 0.1-1% of antioxidant and 0.1-1% of weather-proof agent. The polypropylene composition can be made into decorations in automobiles through injection molding. Various properties of the polypropylene composition meet the requirements for usage; and the polypropylene composition overcomes the effect of poor low temperature performance and especially has strong low temperature impact resistance at 0-40 DEG C.

Description

technical field [0001] The invention relates to automobile interior parts, in particular to a low-temperature impact-resistant polypropylene composition, a preparation method thereof and application as an automobile interior part. Background technique [0002] Due to its light weight, solvent resistance, easy processing, excellent mechanical properties, and easy recycling, polypropylene has been widely used, especially in the automotive industry, home appliances and machinery. In the future, the automobile industry will develop in the direction of energy saving, environmental protection and safety. This requires the materials used to be light in weight, simple to process, easy to recycle, etc., and polypropylene meets these requirements. However, polypropylene material has poor low-temperature resistance and low rigidity, and cannot meet the requirements for automotive interior parts. It must be modified to improve its low-temperature performance and rigidity to meet the re...
