Problems solved by technology

At present, the general LED lamp does not adopt special heat dissipation measures, and uses the natural heat dissipation of the lamp housing. This method causes the lamp housing to age after the LED lamp has been used for a period of time. Due to the long-term high temperature of the lamp housing, the service life of the LED is reduced; it cannot meet Development Status and Requirements of LED Lamps

Abstract

The invention provides an organic silicone resin heat dissipating coating and a preparation method thereof. The coating is characterized by comprising the following raw materials by weight parts: 20-23 parts of the organic silicone resin, 10-12 parts of E-12 epoxy resin, 12-14 parts of nanometer montmorillonite powder, 3-4 parts of aluminium hydroxide, 3-4 parts of diethylenetriamine, 26-28 parts of xylene, 4-6 parts of propylene glycol, 22-23 parts of aluminium nitride powder, 2-3 parts of vinyl-tris(beta-methoxyethoxy)silane, 1-2 parts of an accelerator M, 8-10 parts of tributyl citrate, 1-2 parts of zinc naphthenate, 1-2 parts of stearic acid, 2-3 parts of acrylonitrile and 3-4 parts of a film forming agent. Through composite solidification of the organic silicone resin and the E-12 epoxy resin, adhesion stress of the heat dissipating coating is improved, thereby preventing falling off and being high in service life.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a heat-dissipating coating, more specifically, an organic silicon resin heat-dissipating coating and a preparation method thereof. Background technique [0002] With the rapid expansion of the use of LED lamps, prolonging the service life of LED lamps has become an urgent problem to be solved. At present, the general LED lamp does not adopt special heat dissipation measures, and uses the natural heat dissipation of the lamp housing. This method causes the lamp housing to age after the LED lamp has been used for a period of time. Due to the long-term high temperature of the lamp housing, the service life of the LED is reduced; it cannot meet The development status and requirements of LED lamps. Contents of the invention [0003] The object of the present invention is to provide a silicone resin heat-dissipating coating and a preparation method thereof. The coating of the present...
