ABS / attapulgite composite material and preparation method thereof

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...

Embodiment 1

[0045] 1) Vacuum drying the attapulgite (200 mesh, Jingyuan, Gansu) at 80°C for 4 hours to obtain the dried attapulgite;

[0046] 2) Weigh 6.5 kg of ABS (Toray, Japan, T-300, melt index is 10), 2.5 kg of dried attapulgite and maleic anhydride grafted polypropylene (353D, DuPont, USA, grafting rate 1.0) 1.0 kilograms are premixed in a premixer (200 revs / min) to obtain a mixed material;

[0047] 3) Adding the mixed materials into a twin-screw extruder for melt blending, extruding and granulating to obtain a granular ABS / attapulgite composite material. Among them, the temperature of each section of the mixed material in the twin-screw extruder is respectively: the temperature of the feeding section is 210°C, the temperature of the compression section is 220°C, the temperature of the metering section is 225°C, the temperature of the head is 225°C, the speed of the twin-screw extruder is 300 rpm. The screw length-to-diameter ratio of the twin-screw extruder was 40:1.
