Abstract

The invention relates to a PC-ASA alloy material with the excellent low-temperature toughness and a preparation method thereof. The alloy material is prepare from 35-75 parts of PC resin, 20-60 parts of ASA resin, 5-15 parts of PE resin, 1-3 parts of compatibilizers, 0.1-1 part of antioxidants and 0.1-1 part of lubricating agents. The preparation method comprises the steps that all the raw material components are weighed by weight and then put in a mixing stirrer to be fully mixed, the mixture is fed in a double-screw extruder for fusing, extruding, bracing, cooling and pelleting, and then the PC-ASA alloy material with the excellent low-temperature toughness is prepared. Compared with the prior art, the PC-ASA alloy material has the advantages of being excellent in low-temperature toughness, low in cost, capable of easily achieving industrialized production and the like.

Description

technical field [0001] The invention relates to an alloy material and a preparation method thereof, in particular to a PC / ASA alloy material with excellent low-temperature toughness and a preparation method thereof. Background technique [0002] PC (polycarbonate) material has excellent mechanical properties, while ASA (acrylonitrile-styrene-acrylate) has excellent light resistance and processing performance. PC / ASA alloy material takes into account the advantages of both. And other fields have a wide range of applications, especially in recent years, the automobile consumer market is booming, and the trend of automobile lightweight and replacing steel with plastic makes the use of PC / ASA alloy materials in the automobile field more and more. [0003] Compared with PC / ABS alloy materials, PC / ASA alloy materials have better light resistance. In some parts that require high light, such as interior rearview mirrors, the light resistance of PC / ABS often cannot meet the requireme...
