Abstract

The invention belongs to the technical field of plastic, and particularly relates to an antistatic agent for plastic and a preparation method of the antistatic agent. The antistatic agent for plastic is prepared from glyceryl tristearate and pentaerythritol stearate, wherein the weight ratio of glyceryl tristearate to pentaerythritol stearate is (1-4):1. The antistatic agent is superior in antistatic performance and good in compatibility with resin, the antistatic agent can be used in cooperation with other auxiliaries, the raw material cost is low, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to an antistatic agent for plastics and a preparation method thereof. Background technique [0002] Any object has its own static charge. The accumulation of static charge will affect or even endanger life or industrial production. Chemicals that guide or eliminate the accumulated harmful charges so that they do not cause inconvenience or harm to production and life are called anti-static chemicals. Static agent. [0003] According to different ways of use, antistatic agents can be divided into two types: external coating type and internal mixing type. According to the ionic properties of surfactants, antistatic agents can be divided into cationic, anionic, zwitterionic and nonionic. [0004] External coating antistatic agent refers to a class of antistatic agent used on the surface of polymer materials. Generally, it is formulated into a solution with water or alcoh...
