Abstract

The invention belongs to the field of modified polypropylene composite materials and relates to a scratch-resistant modified polypropylene composite material which is applicable to manufacturing automotive interior parts and comprises the following components by parts by weight: 60-90 parts of polypropylene, 5-20 parts of plasticizer, 5-20 parts of mineral filler, 0.1-4 parts of wear-resistant agent/scratch-resistant agents and 0.1-3 parts of additives, wherein the wear-resistant agent/scratch-resistant agents can be selected from the mixture of nano-polytetrafluoroethylene superfine micro-powder, organic matter-modified siloxane, modified silicone mixture and reactive modified polysiloxane. The prepared modified polypropylene composite material has high surface gloss and better impact-resistant performance, strength, melt fluidity and mechanical performance; furthermore, due to the use of the various wear-resistant agents/scratch-resistant agents, the scratch-resistant performance of the product is excellent; and the resources of the required raw materials are simultaneously extensive and easy to obtain.

Description

technical field [0001] The invention belongs to the field of modified polypropylene composite materials, in particular to a kind of wear-resistant agent / scratch-resistant agent-modified polypropylene composite material, and in particular to a kind of scratch-resistant modified polypropylene suitable for manufacturing automotive interior parts Composite material; the present invention also relates to the preparation method of the modified polypropylene composite material. Background technique [0002] Compared with engineering plastics, polyolefin materials such as polypropylene, toughener-modified polypropylene, thermoplastic polyolefin and thermoplastic elastomer have the advantages of recyclability, light weight and low cost, so they are increasingly used in automotive and other fields. 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. S...
