Problems solved by technology

The introduction of the electroplating process makes it have a good appearance. Due to the existence of the rubber phase in the ABS material, it can often be processed relatively well in the electroplating process, but the electroplating performance of the PC material is relatively poor. Combined with excellent performance, while satisfying its flame retardant performance and electroplating performance, and has little influence on other performances, it has become the focus of the present invention

Description

technical field [0001] The invention belongs to the technical field of polymer alloy materials, and relates to a flame-retardant PC / ABS alloy material with good electroplating performance and a preparation method thereof. Background technique [0002] At present, polycarbonate and acrylonitrile-butadiene-styrene graft copolymer alloy materials (PC / ABS alloy) have been continuously developed, and have a series of advantages such as high toughness, high temperature resistance, and low price, but in some cases On the one hand, the lower material puts forward higher requirements on its flame retardancy, on the other hand, it has further requirements on its secondary processing. The introduction of the electroplating process makes it have a good appearance. Due to the existence of the rubber phase in the ABS material, it can often be processed relatively well in the electroplating process, but the electroplating performance of the PC material is relatively poor. Combining excell...
