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 a composite heat dissipation coating composition and a preparation method thereof. The coating composition is characterized by comprising the following raw materials by weight parts: 40-45 parts of E-12 epoxy resin, 6-8 parts of 2-methyl methacrylate, 3-4 parts of tetraethylenepentamin, 20-24 parts of nanometer diatomite powder, 8-10 parts of nanometer calcium carbonate powder, 2-3 parts of zinc oxide, 10-12 parts of methyl ethyl ketone, 16-18 parts of xylene, 4-6 parts of propylene glycol, 2-3 parts of aluminium nitride powder, 2-3 parts of vinyl-tris(beta-methoxyethoxy)silane, 3-4 parts of an accelerator M, 2-3 parts of methacrylic acid-2-hydroxy ethyl ester, 4-6 parts of aluminium nitride and 3-4 parts of a film forming agent. The coating composition is reasonable in formula, aging resistant, large in adhesive strength and good in heat-dissipation effect, can be used under 200 DEG C for a long term, and has unchangeable mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of paints, and relates to a heat-dissipating paint, in particular to a composite heat-dissipating paint composition 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 composite heat-dissipating paint composition and a preparation method thereof. The paint of the present inven...
