Abstract

The invention discloses an antistatic high-luster polypropylene composite material and a preparation method thereof. The composite material is prepared by using 100 parts of polypropylene, 50-100 parts of acrylonitrile-butadiene-styrene copolymer, 9-30 parts of an antistatic agent, 4-10 parts of a compatilizer, 10-20 parts of a modification filler, 1-2 parts of an antioxidant and 0.5-1 part of a processing assistant, wherein the antistatic agent is composed of a permanent high-molecular antistatic agent and a low-molecular antistatic agent; and the compatilizer is a polypropylene grafted maleic anhydride and acrylonitrile-butadiene-styrene copolymer grafted maleic anhydride mixture. The preparation method improves the antistatic performance, the comprehensive performances and the cost performance of the polypropylene composite material, so the composite material has the characteristics of permanent antistatic performance, high luster and workability, and can be widely used in the field of electronic apparatuses, the field of household electrical appliances, the fields of aviation and aerospace, the national defense field and the like.

Description

[0001] technical field [0002] The invention relates to the field of polymer material modification, in particular to the preparation and method of an antistatic and high-gloss polypropylene composite material. [0003] Background technique [0004] Plastics are used more and more widely, and polypropylene (PP) as a general-purpose plastic has attracted more and more attention, and its application range has also been greatly expanded. However, in some fields due to the high shrinkage rate of polypropylene (1.4~1.6%), large surface resistivity (10 16 ~10 18 Ω), poor gloss and other shortcomings, making pure polypropylene not widely used. With the development of science and technology, a single plastic can no longer meet the needs of social development in some fields. In recent years, plastic alloys and their modifications have been widely used, and the modified polypropylene has a wide range of applications. At present, the method of reducing the shrinkage of polypropyle...
