Problems solved by technology

However, the price of PC is relatively expensive, the processing temperature is high, the residual stress is large, and the fluidity is poor, which limits the application of PC to a large extent.
Compared with PC, acrylonitrile-butadiene-styrene copolymer (ABS) is cheap, has excellent performance, has gloss, and is easy to form and process, but its heat resistance is poor

Description

technical field [0001] The invention relates to an aging-resistant and antibacterial PC / ABS blended alloy and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Polycarbonate (PC) is an increasingly widely used engineering plastic, which has comprehensive and stable mechanical properties, thermal properties and electrical properties. However, the price of PC is relatively expensive, the processing temperature is high, the residual stress is large, and the fluidity is poor, which limits the application of PC to a large extent. Compared with PC, acrylonitrile-butadiene-styrene copolymer (ABS) is cheap, has excellent performance, has gloss, and is easy to form and process, but its heat resistance is poor. By blending PC and ABS, an alloy with good overall performance and relatively high performance and price can be obtained. The solubility parameter of PC is 19.5 (J / cm 3 )1 / 2, the solubility parameter of ABS is ...
