The invention relates to the technical field of plastic coatings, in particular to a PC laser coating, an adapter shell and a preparation method thereof, wherein the PC laser coating comprises the following raw materials in parts by weight: polycarbonate, a flame retardant A, polytetrafluoroethylene, an organic silicon flame-retardant synergist, a toughening agent, a coloring agent, a smoke suppressant and a wear-resisting agent; the colorant is high-pigment carbon black toner with the particle size of 4-15nm, or the colorant is titanium dioxide with the particle size of 4-12 mu m; the titanium dioxide is prepared from anatase titanium dioxide and rutile titanium dioxide in a weight ratio of 1: 3-4. The PC laser coating has excellent wear resistance, hardness, flame retardance, smoke suppression and anti-dripping performance, and is attractive and elegant in color, part of the coating layer can be burnt out in a laser mode to laser the graphic information, and the prepared graphic information is high in precision and attractive and clear. |
