Abstract

The invention discloses an antistatic PP/ABS composite material and a preparation method thereof. The composite material is prepared from the following raw materials in parts by weight: 100 parts of polypropylene, 50-100 parts of acrylonitrile-butadiene-styrene copolymer, 6-20 parts of polyethylene glycol oleate, 2-8 parts of sodium polyacrylate, 4-10 parts of a compatilizer, 20-50 parts of a filling material, 1-2 parts of an anti-oxidant, 0-1 part of N,N'-ethylenebis(stearamide), 0-1 parts of 3-aminopropyltriethoxysilane, and 0.5-30 parts of ethylene-octene copolymer. The antistatic performance, the comprehensive performance and the cost performance of the polypropylene composite material are improved, the composite material disclosed by the invention has the characteristics of persistent antistatic performance, high glossiness, processing easiness and the like, and is wide in application fields, such as electric appliances, household electrical appliance, aviation spaceflight, national defense and the like.

Description

[0001] technical field [0002] The invention relates to the field of polymer material modification, in particular to a preparation and method of an antistatic PP / ABS 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 polypropylene generally adds filler...
