Abstract

The invention discloses an antibacterial PC / ABS alloy material and a preparation technology thereof. The preparation method comprises the following steps: (1) drying PC at the temperature of 110-130 DEG C for 3-4 h, and drying ABS at the temperature of 80-90 DEG C for 2-4 h; (2) placing ABS, PC, a compatilizer, kaolin, a flexibilizer and an antioxidant into a high-speed mixer, and uniformly mixingto obtain a mixture; and (3) pouring the mixture into a hopper of a double screw extruder, and extruding and pelletizing. According to the invention, the influence of components on performance of thePC / ABS alloy is researched, mechanical property, processing fluidity, thermal performance and microstructure of a blend system are comprehensively considered, and the best ratio is determined. By selecting a modifier for modification treatment of kaolin and testing antibacterial and mechanical effects, the antibacterial PC / ABS alloy material has respective original excellent properties of PC andABS and also has advantages of good antibacterial property, excellent mechanical property, good heat resistance, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to an antibacterial PC / ABS alloy material and a preparation process thereof. Background technique [0002] Polycarbonate (Polycarbonate), referred to as PC, is a polymer whose main chain contains carbonate bonds. Polycarbonate can be roughly divided into two categories: one is aromatic carbonate, mainly bisphenol A polycarbonate; the other is aliphatic polycarbonate. [0003] ABS is a copolymer of acrylonitrile (A), butadiene (B) and styrene (S), which has good chemical corrosion resistance, good flow performance and impact resistance, and high cost performance. PC / ABS alloy can combine the excellent properties of PC, on the one hand, it not only maintains the heat resistance, high strength, high modulus and other advantages of PC; Performance; and reduce the internal stress of the product, improve the low temperature notched impact strength of PC, and more importantl...
