Abstract

The invention provides a light diffusion master batch and a preparation method thereof. The light diffusion master batch is mainly prepared from the following raw materials in percentage by weight: 78-88 percent of an optical transparent polymer, 10-20 percent of a light diffusion agent, 0.5-2 percent of a liquid adsorbent and 0.1-0.3 percent of a stabilizer. The light diffusion agent is added into the optical transparent polymer matrix so as to obtain the high-concentration master batch, and the liquid adsorbent is adopted, so that the light diffusion agent can be uniformly adsorbed to the optical transparent polymer, and the aim of uniformly distributing the light diffusion agent on the surface of the optical transparent polymer particles is achieved. Meanwhile, with the adoption of the liquid adsorbent, the surface of the light diffusion agent is full of the liquid adsorbent in an adhered mode, and the light diffusion agent is difficult to drift away in the subsequent operation.

Description

technical field [0001] The invention belongs to the technical field of functional master batches, and in particular relates to a light-diffusing master batch and a preparation method thereof. Background technique [0002] To make ordinary transparent polymer materials have light-diffusing properties, a common method is to add a certain amount of light-diffusing agent with a refractive index different from that of the material to the transparent material, and make the light-diffusing agent evenly distributed in the plastic substrate. When the light passes through, the light will be refracted on the surface of the tiny light diffusing agent. If the light diffusing agent itself is a light transparent body, the light can penetrate the light diffusing agent body, and then refract after passing through. The interior of the material is refracted countless times to obtain a uniform light effect. [0003] However, light diffusing agents are usually microbeads with very fine particle...
