The invention relates to the field of material technology, and discloses a piano-black spray-free ABS/PMMA alloy material and its preparation method. ABS resin, PMMA, self-made ABS grafted powder, hexachlorocyclotriphosphazene flame retardant, Antioxidant 1010, phosphite antioxidant 168, organic black pigment and calcium stearate processing aid are stirred and mixed evenly. After drying, the mixture is added into the main feeding hopper of a co-rotating intermeshing twin-screw extruder, and processed through melt extrusion, cooling, granulation and drying to prepare the piano-black spray-free ABS/PMMA alloy. The self-made ABS dual-monomer grafted copolymer effectively improves material toughness with low addition dosage without reducing surface gloss. High-efficiency organic black pigment is uniformly dispersed in the matrix to achieve a perfect piano-black visual effect.
