Abstract

The invention discloses a PC (Poly Carbonate)/ABS (Acrylonitrile Butadiene S) alloy material and a preparation method thereof. The PC/ABS alloy material comprises the following formulation components in weight percentage: 56-65 percent of PC, 6-10 percent of ABS, 7-12 percent of halogen-free flame retardant, 8-18 percent of glass fiber and 4-16 percent of other additives. The PC/ABS alloy material takes the PC and the ABS as the base materials, the synergic action is caused during the melt extrusion of the glass fiber and other components, the PC/ABS alloy material is endowed with high strength, and meanwhile, the PC/ABS alloy material has excellent processability and thermal properties, and meets the environmental protection requirement. The preparation method is simple in process, easy to control in conditions, low in cost and equipment requirement, and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a PC / ABS alloy material and a preparation method thereof. Background technique [0002] PC / ABS alloy material is a modified plastic made by mixing polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS). This modified plastic has better performance than pure PC and ABS. Well, on the one hand, it can improve the heat resistance and tensile strength of ABS, on the other hand, it can reduce the melt viscosity of PC, improve the processing performance, so that it can be used to form large-area and complex products, and at the same time reduce the internal stress of the product. Improve low temperature impact resistance. Therefore, PC / ABS alloy materials have been widely used in the fields of communication electronics, household appliances, and automobile industries, especially high-gloss PC / ABS alloy materials, which are widely used in high-end export LCD TV casings, ...
