[0028] Step A, preparation of prefabricated body: by weight, take 20-30 parts of fatty acid calcium, heat to 150-170°C, then add 20-30 parts of silicon oxide powder, 0.5-1 part of glass fiber, stir evenly, and cool Finally, the modified powder is obtained; then the modified powder is mixed with 10-20 parts of polyethylene in a mixer, and then 5-10 parts of ethylene bisstearamide and 5-10 parts of chlorinated polyethylene are added. After heating up, mix evenly, and cool to room temperature to obtain a preform;
[0029] Step B, the preform in step A and 40-60 parts of polycarbonate, 3-5 parts of butanediol diacrylate, 0.5-1 part of antioxidant, 0.5-1 part of silane coupling agent, 0.5 parts of lubricant -1 part, mix well to get a mixture;
[0030] Step C, sending the mixture into a twin-screw extruder for extrusion and granulation.
[0031] The heat dissipation coating 5 described in the present invention comprises the following components by weight:
