Abstract

The invention belongs to the field of modified polypropylene composite material, and relates to a low-VOC scratch-resistant modified polypropylene composite material which is applicable to manufacturing automobile interior trim parts, and comprises the components based on the parts by weight: 60-90 parts of polypropylene, 5-20 parts of toughening agent, 5-20 parts of mineral filler, 0.1-4 parts of odor adsorbent, 5-15 parts of wear-resistant agent / scratch-resistant agent and 0.1-3 parts of auxiliary agent, wherein the odor adsorbent is a mixture of three selected from clay, bentonite, porous silicon dioxide, activated aluminium oxide or molecular sieve; and the wear-resistant agent / scratch-resistant agent is one or a mixture of two in polytetrafluoroethylene micro powder or reaction-type polyorganosiloxane. The modified polypropylene composite material not only has better impact-resistant performance and strength, but also has excellent scratch-resistant performance and low-VOC diffusion characteristic; and the needed raw materials have wide source and can be conveniently and easily obtained.

Description

technical field [0001] The invention belongs to the field of modified polypropylene composite materials, in particular to a polypropylene composite material modified by an anti-wear agent / scratch-resistant agent, and in particular to a low-VOC scratch-resistant modification suitable for manufacturing automotive interior parts Polypropylene composite material; the present invention also relates to a preparation method of the modified polypropylene composite material. Background technique [0002] Polypropylene is widely used in automobiles due to its low density, high cost performance, excellent heat resistance, rigidity, chemical corrosion resistance, easy processing and recycling, and has become the largest and fastest growing plastic in automobiles. The fast variety. However, polyolefins are significantly less resistant to scratches, which is a critical property for automotive interior applications such as instrument panels, consoles and door skins. Scratch resistance is...
