Abstract

The invention provides a low-odor scratch-resistant polypropylene material, which comprises the following components in percentage by weight: 65 to 75 percent of polypropylene resin, 1 to 8 percent of odor absorbent, 10 to 30 percent of filler, 1 to 5 percent of scratch-resistant agent, 0.1 to 0.5 percent of antioxidant and 0.1 to 0.5 percent of lubricating agent. The invention also provides a method for preparing the low-odor scratch-resistant polypropylene material. The low-odor scratch-resistant polypropylene material has the characteristics of low odor volatility, high surface scratch resistance and high mechanical properties, and is suitable for auto interior materials.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a low-odor and scratch-resistant polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is one of the five general-purpose plastics, with a density of 0.90g / cm 3 , is the second lightest polymer material in existing resins (only greater than polymethylpentene, density 0.85g / cm 3 ). Because of its good performance, small specific gravity, and easy molding and processing, it is widely used in the automobile industry, household appliances, electronic instrument industry, and textile industry. [0003] In recent years, due to the rapid development of engineering modification of polypropylene materials, its application in the automotive field has become more and more extensive. However, as an important part of engineered polypropylene materials in the automotive field, various automotive interior parts made of...
