Abstract

The invention relates to the technical field of LEDs, in particular to a water-based light diffusion coating. The coating is prepared from 20-30 parts of water-based polyacrylic acid resin, 15-20 parts of high temperature resistance organic silicon resin, 5-15 parts of a light diffusion agent, 3-7 parts of an emulsifying agent, 1-1.5 parts of a defoaming agent, 2-7 parts of inorganic pigment, 3-5 parts of an active additive, 2-4 parts of a dispersing agent and 5-15 parts of a mixed solvent. According to the water-based light diffusion coating, the problems of LED lamp glare, light pollution and the like are solved, the light source is uniform, soft and full, the light permeability and light scattering performance are good, the cooling effect is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a water-based light-diffusing paint and a preparation method thereof. Background technique [0002] LED is a point light source. When it is used as a light source for lamps and lanterns, it needs to have a lampshade that diffuses light and has a good light transmittance in order to avoid the glare problem. Glass lampshade is currently the most commonly used lampshade. Glass has good light transmittance, but the glare problem is particularly serious when it is used as an LED lampshade. For this reason, most of the prior art uses solvent-based light-diffusing coatings to coat glass lampshades. , form a light diffusion coating on its inner surface (the outer surface is also acceptable, but it is easy to fall off due to wear and tear, so it is not used in most cases), so that the light emitted by the LED light source is refracted and scattered, and diffused to form a soft light, but thi...
