Problems solved by technology

[0002] PC / ABS (a blend of polycarbonate and acrylonitrile-butadiene-styrene copolymer) resin is an alloy material with excellent performance, with excellent physical and mechanical properties, surface hardness, high strength and flow and has certain heat resistance, but due to the high insulation of the polymer itself, static electricity is not easy to disappear from the charged plastic, such as dust sticking to the plastic product, giving the user or operator of the product an electric shock , or cause counters, integrated circuit chips to work abnormally, etc., so it is necessary to conduct necessary research on preventing plastics from being charged with static electricity
[0003] At present, the antistatic materials commonly used in the market are mainly to add some low molecular weight antistatic agents to the materials, relying on the precipitation of low molecular weight substances to form a hydrophilic layer on the surface of the material to produce antistatic effects, but its main disadvantage is that the antistatic time is short and not Washable, the antistatic effect will be lost in a short time, and some permanent antistatic agents currently on the market use a large amount (generally around 20% to play a role), which will affect the mechanical and heat resistance of the material, etc. will have a certain impact on
