Abstract

The invention relates to a preparation method of a heat-dissipation coating for LED (Light Emitting Diode) lamps. The preparation method comprises the following steps of: firstly preparing the following components in percentage by weight: 30-60% of silicon resin, 15-40% of n-butyl acetate, 5-10% of nanometer silicon dioxide, 13-40% of aluminum nitride, 15-20% of beryllium oxide, 1-2% of curing agent and 0.5-5% of dust preventive and smoothing agent mixture; fully mixing the materials; fully stirring the heat-dissipation coating, then pouring the stirred heat-dissipation coating into a spray gun and aligning the spray gun at the surface of a part to be sprayed for to-and-fro spraying to ensure that the heat-dissipation coating evenly covers the surface of the part; and curing. The heat-dissipation coating for the LED lamps has the advantages of high radiation cooling performance and convenience in use, and is used for reducing the surface temperature of heat-dissipation cups, aluminum substrates, lampshades and the like in the LED lamps so as to achieve the cooling effect. The heat-dissipation coating for the LED lamps has excellent protection and decoration effects, and has the characteristics of good self-cleaning performance, water repellency, fire retardancy, insulation performance and convenience in construction besides the radiation cooling performance.
