Problems solved by technology

[0003] (1) The weather resistance and water resistance of the product generally cannot meet the requirements;
[0004] (2) In the event of a fire, the film-forming substances of these fire-resistant coatings cannot withstand the sharply rising temperature and are quickly burned, and cannot play the role of fire prevention;
[0005] (3) Poor performance in anti-corrosion, acid and alkali resistance;
[0006] This greatly affects the service life of the LED coating

The heat radiation paint is prepared from the following ingredients: drift-sand, polyfluortetraethylene particles, nanometer titanium dioxide, purple sand, silicon nitride, KH-560, KH-550, epoxy-terminated polyether amine, beta-cyclodextrin modified amino-terminated sulfonated polybenzimidazole, 1,4,5,8-naphthalenetetracarboxylic dianhydride, 8-naphthylamine-1-sulphonic acid, 1,5-naphthalenedisulfonic acid, lauryl mercaptan, ethanol and de-ionized water.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a heat dissipation coating for LED lamps. Background technique [0002] Under the current background of rising global energy shortage concerns, energy conservation is an important issue we will face in the future. In the field of lighting, the application of LED lighting products is attracting the attention of the world. LED has high luminous efficiency, long service life, With many advantages such as energy saving and environmental protection, it is more and more widely used in many fields. It is a new type of light source in the 21st century, with advantages that traditional light sources cannot compare with, such as high efficiency, long life, and not easy to break. Currently, LED lamps currently on the market are generally coated with heat-dissipating paint on the surface, but the existing heat-dissipating paint has the following disadvantages...
