Abstract

The invention relates to a processing method of a diffusion plate and belongs to the field of manufacturing of diffusion plates. The processing method of the diffusion plate comprises the steps of pretreatment, stirring treatment, extrusion treatment, impurity removal, die forming, diffusion plate forming and the like. In pretreatment, polymethyl methacrylate and diffusion powder are respectivelydried at a drying temperature of 80 DEG C; and in stirring treatment, 100KG of the pretreated polymethyl methacrylate and 0.8-2.8KG of the pretreated diffusion powder are taken for mixing stirring treatment at a stirring speed of 800 r / min. The processing method of the diffusion plate has the beneficial effects that the diffusion plate processed by the method is good in impact resistance, has theheat softening temperature reaching 100 DEG C or more, can adapt to high-temperature application environment and is not prone to aging or deformation.

Description

technical field [0001] The invention relates to a processing method of a diffuser plate, which belongs to the field of diffuser plate manufacture. Background technique [0002] The diffusion plate has the optical characteristics of plastic sheets such as high haze, high light transmittance, and high diffusivity. It can effectively convert point or line light sources into soft and uniform surface light sources. On the premise of achieving good light transmittance, At the same time, it has good light source dot matrix shielding, is an ideal optical material to solve the secondary light distribution of LED lighting products, and is the best light diffusion material for LED lighting products. However, in some working environments, the operating temperature of the diffuser plate is higher than 100°C, and the existing diffuser plate products generally begin to soften above 90°C, which cannot meet the needs of high-temperature environments. Contents of the invention [0003] The...
