Low-filler antistatic and highly-tough ABS plastic and preparation method thereof

Abstract

The invention relates to a low-filler antistatic and highly-tough ABS plastic and a preparation method thereof. The preparation method comprises the following steps: swelling natural rubber particlesin toluene; adding the swelled natural rubber particles to a carbon black suspension formed by dimethylformamide and deionized water to make the carbon black penetrate into the natural rubber particles, washing the natural rubber particles with deionized water, and drying the washed natural rubber components to a constant weight; blending 100 parts by weight of ordinary ABS plastic, 5-10 parts byweight of an ethylene-acrylic acid copolymer, 10-30 parts by weight of natural rubber penetrated with the carbon black particles, 0.1-3 parts by weight of a coupling agent and 0.1-0.4 part by weight of an antioxidant; and extruding the obtained mixture at 160-210 DEG C, and cooling the extruded mixture to obtain low-filler antistatic and highly-tough ABS plastic particles. The ABS plastic preparedin the invention has the advantages of low filler content, good antistatic property, easiness in processing, and good mechanical properties.

Description

technical field [0001] The invention belongs to the field of ABS plastics, and in particular relates to an antistatic high-toughness ABS plastic with low filler content and a preparation method thereof. Background technique [0002] ABS plastic is a kind of general-purpose plastic, which has a wide range of applications in the field of electrical appliances, and is often used in electrical casings, etc. When applied in this field, ABS is required to have good toughness, impact resistance and antistatic properties. However, ABS is a brittle and insulating plastic material. The way to improve the toughness and antistatic properties of ABS is to add rubber particles and conductive particles. The addition of conductive particles will degrade the processability and mechanical properties of the material. How to comprehensively realize the toughness and antistatic properties of ABS is an urgent problem to be solved. [0003] Chinese invention patent CN104693335B discloses a meth...

Problems solved by technology

However, the addition of 15wt% zinc oxide whiskers in this method will have a significant impact on the toughness of ABS

[0005] In the above preparation methods, through the improved method of in-situ synthesis or the way of adding a large amount of conductive fillers, the process is complicated and the amount of fillers is high.
