Problems solved by technology

For example, when PC materials are used in the 3C industry, on the one hand, 3C products have different shapes according to consumers’ preferences, but the fluidity of PC materials is poor, and the processing and molding performance needs to be improved, especially when used to form thick-walled transparent products , can not be designed in any shape according to the designer's intention. Second, because PC is not easy to process, the secondary processing performance is poor, the yield rate is low, and the chemical resistance is poor.

Abstract

The invention relates to the field of rubber materials, in particular to a high-temperature-resistant easy-to-form PC/PCTG material and a preparation method thereof. The high-temperature-resistant easy-to-form PC/PCTG material is prepared from the following components in percentage by mass: 50-70% of PC, 20-60% of PCTG, 0.05-0.3% of a lubricating agent, and 0.2-0.4% of an anti-oxidant. The high-temperature-resistant easy-to-form PC/PCTG material is high in flowing property, is good in processing and forming property, is good in heat resistance and is high in mechanical strength.

Description

technical field [0001] The invention relates to the field of plastic raw materials, in particular to a high-temperature-resistant and easy-to-shape PC / PCTG material and a preparation method thereof. Background technique [0002] PC is polycarbonate, which is the only transparent material among the five major engineering plastics. It has comprehensive properties such as heat resistance and electricity resistance. At the same time, it also has the characteristics of impact resistance, dimensional stability, flame retardant, etc. It is widely used in glass assembly industry, automobile industry, electronic appliances and other fields, especially in the automobile industry, PC windows have excellent impact resistance (compared to ordinary inorganic glass) 250 times higher, more than 30 times higher than the standard polymethyl methacrylate glass sheet), light weight, good light transmittance, sound insulation, heat insulation, high cost performance, high potential for chemical ...
