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 However, its disadvantage is that its flame retardancy is poor and it has high electrical insulation, so it is necessary to add various modifiers to the PC / ABS alloy to improve its performance.
The high insulation of the polymer itself makes it difficult for static electricity to disappear from the charged plastic, which will cause dust to stick to the plastic product, electric shock to the user or operator of the product, abnormal operation of the counter or integrated circuit chip, etc. Therefore, it is necessary to conduct necessary research on preventing plastics from being charged with static electricity. The antistatic materials commonly used in the market are mainly to add some low molecular weight antistatic agents to the materials, which mainly rely on the precipitation of low molecular substances to form a hydrophilic layer on the surface of the material to generate antistatic. effect, but its main disadvantage is that the antistatic time is short, it is not washable, and the antistatic effect will be lost in a short period of time, and some permanent antistatic agents on the market currently use a large amount (generally around 20% to play a role). role), which will have a certain impact on the mechanics and heat resistance of the material
