Embodiment 3

[0023] Example 3: 60 parts of polycarbonate (PC) were dried at 120° C. for 4 hours according to the following components (% by weight); 16.6 parts of acrylonitrile-butadiene-styrene copolymer (ABS) and 12 parts of acrylonitrile-benzene The ethylene copolymer (AS) was dried at 80° C. for 4 hours, and the acrylonitrile content in the acrylonitrile-styrene copolymer (AS) was 38%. Pour the dried polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS) and acrylonitrile-styrene copolymer (AS) into a high-speed mixer and stir at a low speed. While stirring, add 4 parts of ethylene grafted acrylate and 4 parts of methyl acrylate-butadiene-styrene copolymer (MBS) mixture, 1 part of polytetrafluoroethylene (PTFE), 0.1 part of ethylene bis stearic acid amide ( EBS) and 0.6 parts of methyl hydrogen silicone oil mixture, and 0.5 parts by weight of antioxidant, stirred for 2 minutes. Add the mixed raw materials into the twin-screw extruder and blend them for extrusion. The ble...

Abstract

The present invention relates to organic chemical technology, and is one kind of polycarbonate / ABS polymer material and its preparation process. The polycarbonate / ABS polymer material is prepared with polycarbonate 40-70 wt%, ABS polymer 15-40 wt%, acrylonitrile-styrene copolymer 5-15 wt%, roughening compatibilizing agent 3-15 wt%, PTFE 1-3 wt%, lubricant 0.2-1 wt% and antioxidant 0.4-1 wt%, and through drying, mixing, extruding and cutting into grain. The polycarbonate / ABS polymer material has high rigidity and very high impact resistance.

Description

technical field [0001] The invention relates to the field of organic chemistry, in particular to a polycarbonate / acrylonitrile-butadiene-styrene copolymer material with high rigidity and super high impact resistance and a preparation method thereof. Background technique [0002] We know that polycarbonate (PC) / acrylonitrile-butadiene-styrene copolymer (ABS) alloy is an important engineering plastic alloy. This material has good formability, good low temperature impact resistance and High heat distortion temperature and light stability. Compared with PC, it reduces the melt viscosity, improves the processing performance, and greatly improves the stress cracking resistance of the product. It has improved heat and weather resistance compared to ABS. The production cost is between PC and ABS, and it has the good performance of both, which can be better used in automobile, electronics, electrical appliances and other industries. In recent years, PC / ABS alloys have developed ra...
