Amphoteric ionic antistatic agent for acrylonitrile butadiene styrene (ABS) and preparation method of antistatic agent

Abstract

The invention relates to an amphoteric ionic antistatic agent for acrylonitrile butadiene styrene (ABS) and a preparation method of the antistatic agent. The efficient amphoteric ionic high molecular antistatic agent is synthesized from three monomers, namely methyl acrylyl ethyl trimethyl ammonium chloride, sodium p-styrene sulfonate and styrene, by virtue of a free radical emulsion copolymerization process. Applied to an ABS material, the amphoteric ionic antistatic agent prepared by the invention has the advantages of being low in surface resistance, durable in antistatic action, light in color and good in heat resistance; the surface resistivity of the ABS material is reduced to 106-107 omega; the antistatic effect is significantly improved compared with those of conventional small molecular and high molecular antistatic agents; and the antistatic agent disclosed by the invention is easy to synthesize, free from toxicity and pollution, moderate in cost and good in application prospect.

Description

technical field [0001] The invention relates to a zwitterionic polymer antistatic agent and a preparation method thereof, in particular to a zwitterionic antistatic agent which can be used for ABS resin and a preparation method thereof. Background technique [0002] Nowadays, with the increasing development of science and technology, a single polymer material can no longer meet people's requirements for all aspects of material performance, and more and more people pay more and more attention to improving the performance of materials through polymer blending modification. ABS (terpolymer of styrene, butadiene, and acrylonitrile) is widely used in industrial fields such as machinery, automobiles, and electronic appliances due to its excellent mechanical properties, temperature resistance, and easy processing. However, its high surface resistivity and volume resistivity are easy to generate static electricity after friction, and it is not easy to eliminate, which seriously affe...
