The present invention relates to a fingerprint-resistant high-gloss black PMMA/ASA composition and its preparation method. The composition comprises polymethyl methacrylate, acrylonitrile-acrylate-styrene copolymer, self-cleaning modifier PA-g-MAH, and other additives; wherein the mass ratio of polymethyl methacrylate, acrylonitrile-acrylate-styrene copolymer, and self-cleaning modifier PA-g-MAH is (50-80):(20-40):(5-10). The preparation method comprises the following steps: Mixing, by weight parts, polymethyl methacrylate, acrylonitrile-acrylate-styrene copolymer, self-cleaning modifier PA-g-MAH, antioxidant, lubricant, and black pigment; Co-extruding the mixture through a twin-screw extruder to form pellets, followed by melt extrusion to obtain a fingerprint-resistant, high-gloss black PMMA/ASA composite. Compared to existing technologies, this invention ensures excellent compatibility between PA6/66-g-MAH and PMMA/ASA resins, achieving a significantly enhanced fingerprint resistance effect.
