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 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 aniline formaldehyde resin, 3-4 parts of a silane coupling agent KH 5503, 32-36 parts of aluminium nitride powder, 4-6 parts of beryllia, 6-8 parts of silicon carbide, 25-30 parts of xylene, 16-18 parts of ethyl acetate, 3-5 parts of aminopropyl triethoxysilane, 2-3 parts of phenol, 2-3 parts of zine stearate, 4-6 parts of aliphatic acid glyceride, 1-2 parts of butyl mercaptan tin, 3-4 parts of bi-propylene tri-amine, 4-6 parts of dibenzyl amine ether and 5-6 parts of a film forming agent. According to the invention, organic silicone resin is used to form film and solidify, and the formed film is excellent in moisture resistant, waterproof, antirust, cold resistant, ozone resistant and weather resistant performances. The coating is anti-aging, large in adhesion stress and good in heat radiation effect, can be used for a long time under 200 DEG C, and has unchangeable mechanical properties. The beryllia and the silicon carbide are added into the raw materials to increase a wear resistant performance of the coating, and the coating can be used for a long time under 200 DEG C.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a heat dissipation coating, in particular to a heat dissipation coating for an LED lamp 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 heat dissipation paint for LED lamps and a preparation method thereof. The paint of the present invention has...
