Abstract

The invention provides a low-gloss and scratch-resistant polypropylene material and a preparation method thereof. The low-gloss and scratch-resistant polypropylene material comprises the following components in percent by weight: 77-90 percent of polypropylene, 0-15 percent of toughening agent POE (Polyolefin Elastomer), 4-16 percent of silicon dioxide master batches, 0.1-2 percent of antioxidant, 0.1-1 percent of light stabilizer and 0.1-3 percent of other additives. The preparation method comprises the following steps of: firstly adopting linear low-density polyethylene as matrix resin, blending the linear low-density polyethylene with nano silicon dioxide to prepare master batches, then mixing the polyethylene, the silicon dioxide master batches, the antioxidant, the light stabilizer, other auxiliaries and the like according to the ratio, and carrying out melt extrusion and granulation. The invention has the advantages that the preparation process is simple, no environmental pollution is caused, and the prepared polypropylene material has good low-gloss and scratch-resistant performances, and simultaneously also has good dynamic performance.

Description

technical field [0001] The invention relates to a polymer composite material, in particular to a low-gloss scratch-resistant polypropylene material and a preparation method thereof. Background technique [0002] The shape and surface state of some important parts of automobile interior parts, such as instrument panel and door panel, directly affect the appearance of the car. With the development of the automobile industry, people have higher and higher requirements for the comfort and aesthetics of the cab. If the gloss of the interior parts of the cab is high, there will be strong light reflection, which will affect the comfort of the driver. At the same time, the scratch resistance of polypropylene material is poor, but this performance is the key performance of automotive interior parts such as instrument panels, door panels, decorative pillars, etc. Therefore, people have been actively looking for solutions to improve the scratch resistance of polyolefin materials.
