The invention discloses a crack-resistant, aging-resistant and high-shading PC composite material, its preparation method and application in plastic-coated aluminum products. In mass percentage, the material includes: 90%～94% siloxane copolymer PC resin, 2%～6% titanium dioxide, 2%～6% toughener (hydroxyl silicon modified methyl acrylate-butadiene-styrene copolymer). The preparation process: Blend all raw materials evenly, melt, knead, plasticize and extrude in a twin-screw extruder to obtain the finished PC composite. The material has stable performance, effectively solves poor weather resistance and stress cracking defects of plastic-coated aluminum products, and is widely applicable in related fields.
