Permanently antistatic PC/ASA material

Abstract

The invention relates to a permanently antistatic PC / ASA material, which comprises the following components by weight part: 50-70 parts of PC, 20-30 parts of ASA, 10-15 parts of permanent antistatic agent, 2-4 parts of compatibilizer and 0.5-1.0 part of additive, 0.4-0.7 part of antioxidant and 0.1-0.3 part of ultraviolet absorbent, wherein the additive comprises the antioxidant and the ultraviolet absorbent, and the permanent antistatic agent is synthesized based on polyamide and hindered amine polyether; the compatibilizer is of a PC / ASA special alloy modifier, and the PC comprises one or more of high-melting injection molding grade PC; and the ASA comprises one or more of high-gloss and high-mobility ASA. The invention has high gloss, good heat and light resistant performances, permanent anti-static property and wash resistance, thereby prolonging service life, reducing use cost, and being suitable for industrial scale production and large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to the technical field of PC / ASA alloy materials, in particular to a permanent antistatic PC / ASA material. Background technique [0002] PC is polycarbonate, a new type of thermoplastic, with a transparency of 90%, rigidity and toughness, high impact strength, high dimensional stability, wide range of operating temperature, and good electrical insulation properties And heat resistance and non-toxicity, can be molded by injection and extrusion. [0003] ASA is a terpolymer composed of acrylonitrile-styrene-acrylate, which is an engineering plastic developed for the disadvantage of ABS's poor weather resistance. It integrates the impact resistance and weather resistance of acrylate, the chemical resistance and high hardness of acrylonitrile, and the excellent processability of styrene. It has good mechanical properties and excellent weather resistance, and is especially sui...

Problems solved by technology

[0006] At present, 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 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. Not resistant to washing, will lose antistatic effect in a short time
