Anti-corrosion heat dissipation coating used for LED lights and preparation method thereof

Abstract

The invention provides an anti-corrosion heat dissipation coating used for LED lights and a preparation method thereof. The coating is characterized by comprising the following raw materials by weight parts: 45-48 parts of organic silicone resin, 24-26 parts of polyamide polyamine epichlorohydrin resin, 32-34 parts of aluminium nitride, 50-56 parts of xylene, 25-28 parts of butyl acetate, 2-3 parts of urotropine, 3-5 parts of phenyltriethoxysilane, 2-3 parts of aniline methyl triethoxysilane, 10-20 parts of carbon black N 339, 5-15 parts of carbon black N 660, 1-2 parts of triglycidyl isocyanurate, 5-8 parts of sebacic acid propanediol polyester, 3-5 parts of phthalic acid polyester, 2-3 parts of isoprene, 4-6 parts of 2-hydroxy propyl acrylate, 3-4 parts of propylene glycol, 1-2 parts of tert-butyl hydroperoxide, 1-2 parts of m-amino methylamine, 1-2 parts of ethylene diamine and 3-4 parts of a film forming agent. According to the invention, the urotropine is added into the raw materials to improve the anti-corrosion performance of the coating, so that the coating can be applied in various contaminated environments, and high temperature resistant and salt spray resistant capabilities of the coating can be improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a heat-dissipating coating, in particular to an anti-corrosion LED lamp cooling 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 an anti-corrosion heat dissipation coating for LED lamps and a preparation method thereof. The coating of the p...
