Abstract

The invention discloses a high-performance polypropylene composite material for a vehicle seamless airbag instrument board, and a preparation method thereof, wherein the high-performance polypropylenecomposite material comprises the following raw materials by weight: 45-74%of polypropylene, 15-25% of an ultrafine inorganic filler, 10-20% of an elastomer toughening agent, 0.5-3% of a scratch-resistant aid, 0.1-2% of a stabilizer, and 0-5% of other additives. According to the present invention, through the synergistic action of the ultrafine inorganic filler and the special-structure elastomertoughening agent, the optimal balance between the rigidity and the ultrahigh toughness can be obtained, and the product integrates low-temperature impact resistance and heat deformation resistance, further has good scratch resistance, no sticking, low emission, continuous-illumination resistance, long-term heat resistance and the like, further has excellent processing property, and is suitable forvehicle hard plastic seamless airbag instrument boards and related components.

Description

technical field [0001] The invention relates to a polypropylene composite material, in particular to a high-performance polypropylene composite material for an automobile seamless airbag instrument panel, and a preparation method thereof; belonging to the field of polymer modification and processing. Background technique [0002] With the rapid growth of automobile production and sales year by year and the trend of electrification of automobiles, more and more plastic products are used for interior and exterior parts of automobiles. A top priority in design and development. Among all the plastic materials for instrument panel, the polypropylene material used for rigid plastic seamless airbag instrument panel is the most demanding and most difficult to develop. Because such parts need to be subjected to high and low temperature airbag point explosion experiments, the material itself needs to have excellent low temperature toughness without the protection of the foam skin; P...
