Composite material based on recycled polycarbonate and ABS (Acrylonitrile Butadiene Styrene) and preparation method thereof

The invention discloses a composite material based on recycled polycarbonate and ABS (Acrylonitrile Butadiene Styrene) and a preparation method of the composite material, and belongs to the technical field of composite materials. The recycled polycarbonate drinking water bucket is used as a source of polycarbonate, and the antioxidant and the plasticizer are used for enhancing the thermal stability; ammonium bicarbonate is used as an electrolyte, the surface of the carbon fiber is subjected to oxidation treatment by an electrochemical method, and active oxygen-containing functional groups on the surface of the carbon fiber are increased; hydroxyl groups of glycerol and carboxyl groups on the surfaces of the carbon fibers are subjected to esterification reaction, so that more hydroxyl groups are introduced into the carbon fibers; according to a free radical polymerization mechanism, maleic acid is grafted onto the ABS plastic, carboxyl on the maleic acid and hydroxyl on the carbon fiber can be subjected to est
