Abstract

The invention relates to a wear-resistant and scratch-resistant polypropylene composite with high gloss as well as a preparation method and an application of the polypropylene composite. The polypropylene composite comprises the following main raw materials: polypropylene, a silicone rubber-silane coupling agent-hollow glass bead reactant, filler and an additive packet. In the prepared wear-resistant and scratch-resistant polypropylene composite with high gloss, molecular weight distribution of polypropylene is narrow, hollow glass beads and silicone rubber are mainly distributed on the material surface, a workpiece has high surface gloss, good processability and low shrinkage, and an injection molded workpiece is not prone to production of flow marks and can replace workpieces such as ABSwith higher requirements for gloss, wear resistance and scratch resistance of home appliance housings, automobile trim strips, automobile door handles and the like.

Description

technical field [0001] The invention belongs to the field of polymer materials and processing, and in particular relates to a high-gloss, wear-resistant and scratch-resistant polypropylene composite material and its preparation method and application. Background technique [0002] As one of the general-purpose plastics, polypropylene (PP) has the advantages of non-toxicity, low price, low relative density, chemical resistance, high strength, and easy recycling. It is widely used in household appliances, auto parts, and daily necessities. [0003] High-gloss polypropylene, as a material with high gloss, can replace ABS and is widely used in home appliance casings, daily necessities casings, automotive trims, etc. However, compared with ABS, polypropylene has poor wear resistance and scratch resistance, especially Poor abrasion resistance will make the glossiness of polypropylene materials decrease continuously during use, which greatly limits the application fields of polypro...
