[0015] Example 1
[0016] The following components are prepared by weight percentage, 30% silicone resin, 40% butyl acetate, 5% nano silicon dioxide, 40% aluminum nitride, 15% beryllium oxide, 1% curing agent and 0.5 % Dustproof agent and smoothing agent mixture are mixed together thoroughly, stirred in a mixer at 1000 rpm for 3 hours, filtered with a 200 mesh screen to remove impurities, obtained the frosted paint, and then stand; spray the heat dissipation paint The surface of the LED lamp parts (heat dissipation cup, aluminum substrate, lampshade) is cleaned with oil, decontamination; the mixed heat dissipation paint is fully stirred for 2 minutes and then poured into the spray gun; the spray gun is aimed at the LED lamp parts to be sprayed The distance between the two can be adjusted in the range of 5-20cm according to the pressure of the spray gun and the diameter of the spray gun. The pressure of the spray gun is 0.4~0.5MPa, and the diameter of the spray gun is 1.3~1.5mm. A...
