Abstract

The invention discloses an ABS / attapulgite composite material, comprising the following materials, by weight: 49%-70% of ABS, 15%-35% of attapulgite, 3%-20% of compatilizer and 0%-1% of ubricant. Attapulgite is a natural mineral, which belongs to the rod-like structure, and is beneficial to improving the smoothness of surface of the ABS / attapulgite composite material, and the compatibilizer improves compatibility of the ABS and the attapulgite, so as to endow the ABS / attapulgite composite material of the invention with advantages of high hardness, good bending strength; therefore, the composite material shows excellent mechanical properties. The invention also discloses a preparation method of the ABS / attapulgite composite material. The method is simple and easy to operate, can uniformly harmonize the attapulgite and the ABS through simple steps and prepare the ABS / attapulgite composite material with excellent performances.

Description

technical field [0001] The invention relates to the field of plastic materials and their preparation, in particular to an ABS / attapulgite 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 elec...
