Abstract

The invention relates to a heat-dissipating coating for an LED lamp. The heat-dissipating coating for the LED lamp comprises 65-80 parts of organic silicon resin, 1-3 parts of nano silica, 1-2.5 parts of carbon nano-tubes, 1-2 parts of curing agents, 0.1-0.5 part of antifoaming agent, 0.1-0.5 part of stabilizing agent, 3-12 parts of epoxy resin, 3-12 parts of dicyclohexyl phthalate and 2-5 parts of propylene glycol. A preparation method of the heat-dissipating coating comprises the steps that (1) the components in the formula are weighed according to the parts in weight, then the carbon nano-tubes are added to the propylene glycol to form a solution, and the solution is stirred to be uniform at the temperature ranging from 55 DEG C to 65 DEG C; (2) after the organic silicon resin, the nano silica, the epoxy resin, the dicyclohexyl phthalate, the curing agents and the antifoaming agents are uniformly mixed to form a solution, the solution is stirred for 1-1.5 hours at the speed ranging from 550r / min to 650r / min; (3) the solution in the step (1) and the solution in the step (2) are mixed, then the stabilizing agent is added to the mixture, and the mixture is stirred to be uniform.

Description

Technical field [0001] The invention relates to a heat dissipation paint for LED lamps and a preparation method thereof. Background technique [0002] The energy consumption of white light LED is only 1 / 10 of that of incandescent lamps and 1 / 4 of that of energy-saving lamps. The service life can reach more than 50,000 hours, which is more than 50 times that of traditional tungsten filament lamps. There are no harmful substances such as mercury. LED lamps are energy-saving. , Environmental protection, and longevity, therefore, more and more widely used. [0003] However, the current luminous efficiency of LED lamps is still relatively low, and the proportion of electricity converted into heat is relatively high. Because the heat dissipation problem of LED lamps has been plagued by those skilled in the art, how to improve the heat dissipation efficiency, thereby reducing the junction temperature and increasing the lifespan Makes urgent problems. Summary of the invention [0004] The...
