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 fluororesin heat dissipation coating and a preparation method thereof. The coating is characterized by comprising the following raw materials by weight parts: 30-35 parts of polytetrafluoroethylene, 12-15 parts of polyvinylidene fluoride, 2-3 parts of nonylphenol polyoxyethylene ether, 120-125 parts of xylene, 30-35 parts of ethyl acetate, 2-3 parts of cyanuric acid zinc, 3-4 parts of zinc oxide, 5-8 parts of alum powder, 12-14 parts of nano calcium carbonate powder, 8-10 parts of diatomite powder, 1-2 parts of an antioxidant OD, 2-3 parts of a silane coupling agent KH 550, 1-2 parts of urotropine, 10-12 parts of aluminium nitride powder and 4-5 parts of a film forming agent. According to the invention, the fluororesin is used as a base material; the coating is excellent in high and low temperature resistance, dielectric property, chemical stability, weatherability, incombustibility and inviscosity.

Description

technical field [0001] The invention belongs to the technical field of paints, and relates to a heat-dissipating paint, more specifically, a fluororesin heat-dissipating paint 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 fluororesin heat-dissipating coating and its preparation method. The coating of the present invention has the advanta...
