Antistatic ABS (acrylonitrile-butadiene-styrene) modified material and preparation method thereof

Abstract

The invention relates to the technical field of ABS (acrylonitrile-butadiene-styrene) materials, and in particular relates to an antistatic ABS modified material and a preparation method thereof. The modified material comprises the following raw materials in parts by weight: 62-94 parts of ABS resin, 8-12 parts of an antistatic agent, 8-12 parts of a toughening agent, 0.8-1.6 parts of zinc stearate, 0.05-0.15 part of PETS, 0.3-0.7 part of PMI, 0.3-0.7 part of a diffusant and 0.1-0.6 part of an antioxidant, wherein the antistatic agent is a mixture consisting of carbon black and carbon fiber in a weight ratio of 1:(0.8-1.2). According to the preparation method provided by the invention, the antistatic property, processability and shock resistance of the modified material are improved by adding the antistatic agent, the toughening agent, the PETS and the PMI to perform co-blending modification, so that the surface resistivity of the modified material reaches 5-7 orders of magnitude, and is significantly improved in comparison with that of the existing antistatic ABS material.

Description

technical field [0001] The invention relates to the technical field of ABS materials, in particular to an antistatic ABS modified material and a preparation method thereof. Background technique [0002] ABS is an acrylonitrile-butadiene-styrene copolymer. It is an engineering plastic with good comprehensive properties. It has good dimensional stability, outstanding impact resistance, heat resistance, dielectric properties, and wear resistance. Good surface gloss, easy painting and coloring and other advantages. ABS resin has been widely used in household appliances, construction, automobiles, office supplies and other industries. However, the antistatic performance of ABS is poor. If the antistatic performance of ABS can be improved, the application of ABS resin in the fields of automobiles, aviation, office machines, and electronics will be further developed. [0003] For some ABS antistatic products on the market, the upper limit of antistatic is only 9-10 orders of magn...

AI Technical Summary

Problems solved by technology

However, the antistatic performance of ABS is poor. If the antistatic performance of ABS can be improved, the application of ABS resin in automobiles, aviation, office machines, electronics and other fields will be further developed.

[0003] For some ABS antistatic products on the market, the upper limit of antistatic is only 9-10 orders of magnitude; some manufacturers improve the antistatic performance of ABS by adding antistatic agents, but the upper limit of antistatic is only 9-10 orders of magnitude, and adding antistatic agent, the processing performance of the resin deteriorates

In addition, the impact strength of antistatic ABS on the market is generally 3-4KJ / m 2 Left and right, it also limits the application range of ABS resin to a large extent.
