Problems solved by technology

[0003] However, polypropylene materials also have some disadvantages, such as low surface hardness, poor scratch resistance, insufficient fluidity when making large thin-walled parts, and most polypropylene raw materials have unpleasant smell or are harmful to the human body due to the residue of monomers and additives. Harmful irritating odor, especially the introduction of some low-molecular additives after the modification process, will further increase the odor emiss...

Abstract

The invention discloses a high-mobility low-odor scratch-resistant automobile trim polypropylene material and a preparation method thereof. The polypropylene material is made from, by weight, 50-85% of polypropylene resin, 5-25% of mineral filler, 0-20% of basic magnesium sulfate whiskers, 0.6-4.5% of odor-adsorbing masterbatch, 1-3% of a scratch resistant, 5-15% of a toughener, 0-3% of an antioxidant, 0-1% of a light aging resistant, 0-5% of a toner or color masterbatch, and other aids. The material prepared herein has zero-lost mechanical properties and mobility, has significantly reduced odor and greatly improved scratch resistance, and fully meets the requirement of automobile trims for high mobility, scratch resistance and low odor of material.

Description

technical field [0001] The invention belongs to the technical field of polymer modification and processing, and relates to a high-flow, low-odor and scratch-resistant polypropylene material for automobile interior decoration and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, lightweight, safety, comfort and environmental protection are the main trends in the development of the world's automobile industry. Plastics and their composite materials are important materials for automotive interiors. Among automotive plastics, polypropylene With the characteristics of low density, excellent insulation performance, chemical corrosion resistance, easy processing, molding and recycling, it has been widely used in automobiles, and has become the largest and fastest-growing variety of automotive plastics. [0003] However, polypropylene materials also have some disadvantages, such as low surface hardness, poor scratch re...
