Abstract

The invention discloses an acrylonitrile butadiene styrene (ABS) / nerchinskite composite material, which is prepared from 49 to 70 weight percent of ABS copolymer, 15 to 35 weight percent of nerchinskite, 3 to 20 weight percent of compatilizer and 0 to 1 weight percent of lubricating agent. The mechanical properties such as hardness and toughness of the composite material are improved by adding the nerchinskite, the compatilizer and the like into the ABS. The invention also discloses a preparation method for the ABS / nerchinskite composite material. The method comprises the following steps of: fully mixing the ABS copolymer, the nerchinskite, the compatilizer and the selectively added lubricating agent uniformly through mixing equipment to obtain a mixed material; and adding the mixed material into a double-screw extruder, performing melt blending, melt extrusion and granulation, and thus obtaining the ABS / nerchinskite composite material. The material has excellent and stable performance, facilitates industrialized production, and has good economic benefits and broad application prospect.

Description

technical field [0001] The invention relates to the field of plastic materials, in particular to an ABS / halloysite composite material and a preparation method thereof. Background technique [0002] With the rapid development of the plastic industry, its use has penetrated into various fields of the national economy and is widely used. China produces about 5 million tons of waste plastic every year. Acrylonitrile-butadiene-styrene terpolymer (ABS), as an important kind of plastic material, has also been widely used, mainly because ABS is a copolymer of acrylonitrile, butadiene and styrene, It has good comprehensive performance, good chemical corrosion resistance and good processing fluidity, as well as high heat resistance, toughness, impact resistance and rigidity. [0003] ABS is mainly used in household appliances, mechanical parts, office supplies, electronic devices, automobile industry and other fields, such as panels for the manufacture of electronic and electrical p...
