Preparation method of anti-static agent and method for preparing anti-static plastic by utilizing anti-static agent

Abstract

The invention discloses a method for preparing an antistatic agent, comprising the following steps: (1) dispersing graphene powder into a solvent to obtain a graphene dispersion; (2) mixing the graphene dispersion with an adhesive polymer solution Mix evenly; (3) Dilute the mixed solution to a viscosity of 0.5-200Pa.S, and obtain the finished antistatic agent after dilution. The invention also discloses a method for preparing antistatic plastics by using an antistatic agent, which includes the following steps: a. coating the antistatic agent on the plastic substrate with a coating thickness of 90-180nm; b. coating the antistatic The prepared plastic base is placed in an oven, and baked at a temperature of 90-130° C. for 3-15 minutes, and the finished antistatic plastic is obtained after baking. The invention can make the prepared antistatic agent have the excellent performance of stability and wear resistance, and at the same time, the properties of the plastic product itself will not be affected.

Description

technical field

[0001] The invention belongs to the field of antistatic, and in particular relates to a method for preparing an antistatic agent and a method for preparing antistatic plastics by using the antistatic agent. Background technique

[0002] Plastic products are used in various molded products and films due to their excellent characteristics, but in actual use, due to friction, temperature, etc., the surface of plastic products will form static electricity, and plastic products are usually non-conductive. Therefore, dust, etc. will be adsorbed on the surface of the product, or electrical barriers will appear in the public, or electronic equipment will be damaged due to static electricity accumulation and discharge when used in electronic equipment. Therefore, how to prevent static electricity and quickly conduct static electricity has become a research hotspot.
