Abstract

The invention relates to a highly-thermally-conductive water-soluble photodiffusion coating as well as a preparation method of the coating and a preparation method of a coating layer and belongs to the technical field of photology. The coating is characterized by comprising the following components in percentage by weight: 40-50% of water-based polyacrylate resin, 15-25% of nanometer calcium carbonate, 5-15% of nanometer alumina, 0.2-0.8% of dispersant, 0.2-0.8% of defoamer and 20-30% of deionized water. By virtue of the highly-thermally-conductive water-soluble photodiffusion coating as well as the preparation method of the coating and the preparation method of the coating layer, the problems of dazzle, light pollution and the like of the LED light are solved, the light source of the LED light is uniform, soft and full, the coating has the advantages of good light transmittance, light scattering property and heat dissipation effect and long service life; and the preparation method is simple and convenient.

Description

technical field [0001] The invention belongs to the field of optical technology, and specifically relates to a high-conductivity water-soluble light-diffusing coating, a preparation method and a coating preparation method. Background technique [0002] Due to its high luminous efficiency, low efficiency, long life, and environmental protection, LED (light-emitting diode) has gradually replaced some traditional light source products in lighting engineering auxiliary lighting public places. The heat dissipation effect of the traditional LED lamp wall is not ideal, the heat output efficiency is poor, and the lamp life is short. The use of thermally conductive plastics to maximize the formation and achieve effective heat conduction has become a research hotspot in recent years. The light diffusion film material is a kind of material with good light transmission and light scattering properties, which can solve the glare problem of LED lights. In order to avoid the harm of light...
