Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a preparation method of a novel ABS / PC / PMMA composite material. Background technique [0002] ABS (Acrylonitrile Butadiene Styrene) resin is a terpolymer composed of acrylonitrile, butadiene and styrene. Because of the synergistic performance between the three components, ABS resin has high surface hardness, toughness, good low temperature impact resistance, good creep resistance, good dimensional stability, small molding shrinkage, and excellent processing performance. It is widely used in household appliances, mechanical parts, office supplies, electronic devices, automobile industry and other fields, but the scratch resistance of ABS is poor, so spraying is usually used to improve the scratch resistance of the material surface , but spraying will pollute the environment, and it is also difficult to recycle. [0003] PC is a linear carbonated polyester, and the ca...
