A new type of antistatic ABS resin material and preparation method thereof

Abstract

The invention discloses a novel antistatic ABS (Acrylonitrile Butadiene Styrene) resin material and a preparation method thereof. The antistatic ABS resin material comprises the following components in percentage by weight: 40-70 percent of ABS, 5-10 percent of polyaniline, 1-30 percent of modified carbon nanotube, 1-20 percent of carbon black, 2-4 percent of silane coupling agent, 0.1-0.2 percent of toughener, 0.1-0.2 percent of anti-oxidant and 1-2 percent of DCP (Dicumyl Peroxide). The antistatic ABS resin material has the advantages of permanent antistatic property, good effect, high mechanical property, high processability, good application prospect and good comprehensive performance; the surface resistance of the ABS resin can be lowered to 105 omega.centimeter or lower; a permanentantistatic material can be obtained; the used raw materials do not have toxic or side effects; and the method is safe to operate, and has a simple and practical process.

Description

technical field [0001] The invention relates to an antistatic material and a preparation method thereof, in particular to a novel antistatic ABS resin material and a preparation method thereof. Background technique [0002] Surface resistivity is an important index to measure the ability of materials to disperse electrostatic charges. It is generally believed that when the surface resistivity is 10 10 ~10 11 When it is below Ω·cm, the material has good antistatic and accumulation capabilities. Usually, most polymer materials have the characteristics of good electrical insulation and small dielectric constant, and generally belong to non-conductors, and their volume resistivity is about 10. 10 ~10 20 Ω·cm, so in the process of use, the surface generates static electricity accumulation through friction, contact, etc., and the accumulated charge is difficult to eliminate, which is easy to cause electrostatic discharge, and finally a series of hazards, such as causing compon...

AI Technical Summary

Problems solved by technology

Generally, 15% to 25% of carbon black needs to be filled in the ABS resin matrix to give it antistatic and conductive functions, and only when the distance between adjacent carbon black particles is 1.5-10nm, the two particles can conduct each other. When the distance between two adjacent carbon black particles is about 0.35nm, the contact between particles can be approximated as the contact of pure particles, and the high filling of carbon black will lead to poor processability of composite materials, Increased melt viscosity, reduced mechanical properties of the material, easy fall-off of carbon black particles from the composite system, etc. make the resistivity of the material difficult to control, poor durability and limit the singleness of the color of the product, etc.
