The invention discloses heat-dissipation paint for an LED lamp, which is characterized by comprising the following components in percentage by mass: 30 to 50 percent of organosilicon polyurethane prepolymer, 10 to 20 percent of mixed solvent, 1 to 5 percent of silane coupling agent KH560, 8 to 15 percent of beryllium oxide, 15 to 50 percent of aluminium nitride and 1 to 5 percent of oleinic acid. A preparation method comprises the following steps of: firstly, uniformly blending the liquid components; secondly, adding solid components and uniformly stirring; and finally, grinding on a grinder and then packaging. The heat-dissipation paint for the LED lamp in the invention has the advantages of temperature resistance, aging resistance, high adhesion and good heat-dissipation effect.
