Embodiment Construction

[0016] A light diffusing plate that simultaneously improves light transmittance and haze. The raw material formula components of the above light diffusing plate include a base material made of transparent resin and a light diffusing agent. The key is that the light diffusing agent is Titanium nitride, or zinc nitride, or tin nitride, or iron nitride, or copper nitride, or copper phosphide, or iron phosphide, or two or more of the above It is formed by compounding a mixture of substances, and the weight percentage of the above light diffusing agent in the transparent resin is: 0.01-5%.

[0017] The above-mentioned light diffusing agent has an average particle fineness of 1-50 nm.

[0018] The nitride of titanium mentioned above is TiN, and the nitride of zinc is Zn 3 N 2 , tin nitride is Sn 3 N 4 , Iron nitride is Fe 3 N, copper nitride is Cu 3 N, the phosphide of copper is Cu 3 P, the phosphide of iron is Fe 3 p.

[0019] The above-mentioned transparent resin comprise...

Abstract

The invention discloses a light diffusion plate for simultaneously raising the light transmittance and the haze and a matching technology thereof, solving the technical problems that the addition of a light diffusion agent and a fire retardant in the light diffusion plate seriously affects the light transmittance of the light diffusion plate itself. The light diffusion plate comprises a base material consisting of transparent resin and light diffusion agent, wherein the light diffusion agent comprises nitride of titanium, or nitride of zinc, or nitride of tin, or nitride of iron, or nitride of copper, or phosphide of copper, or phosphide of iron, or a mixture of two or more of the above substances, and the weight of the light diffusion agent accounts for 0.01-5wt% of that of the transparent resin. According to the invention, the light diffusion plate prepared by the invention has low hygroscopicity, warping resistance, flame resistance, UV aging resistance and yellowing resistance.

Description

technical field [0001] The invention relates to a light diffusion plate and its supporting preparation process, belonging to the field of lighting and light display, in particular to a light diffusion plate and its supporting production process which can simultaneously improve light transmittance and haze by adding a new type of light diffusing agent. Background technique [0002] Light diffusion panels are often used in billboards, display panels and traditional lighting fixtures. With the vigorous development of the LED industry in the country, LEDs are more and more widely used in the field of lighting, so the development of excellent light diffusion panels is becoming more and more important. For the light diffusion plate, while increasing its haze, it should try not to increase the loss of light passing through the diffusion plate, that is, to ensure high light transmittance and high haze at the same time. To this end, people have carried out a lot of beneficial researc...
