Description

Technical Field

[0001] The invention relates to the technical field of blow hood plate production, in particular to a blow hood plate production and processing method and processing equipment. Background Art

[0002] The blown cover plate is a light diffuser plate, which is a plate on the flat panel lamp. The light diffuser plate uses chemical or physical means to make the light refract, reflect and scatter in different directions when it encounters two media with different refractive indices (densities) on the way, thereby changing the light's path and achieving full scattering of the incident light to produce an optical diffusion effect. There are three types of light diffusers, so a blown cover plate production and processing method and processing equipment are required.

[0003] Although the blown cover panels produced by traditional blown cover panel production and processing methods and processing equipment are resistant to yellowing and impact, they have poor wear resistance and their high reflectivity greatly reduces their anti-yellowing ability. Summary of the invention

To achieve the above purpose, the present invention provides the following technical scheme: a method for producing and processing a blown cover plate, including material selection and preparation steps, the blown cover plate adopts a double-layer (or three-layer) co-extrusion technology, the plate is divided into a main layer and a surface layer, and the thickness ratio is about 4:1; the main layer adopts the formula of anti-impact and anti-yellowing diffusion plate: GPPS, diffusion masterbatch, HIPS, anti-UV masterbatch, the main characteristic is to ensure that the material has the characteristics of anti-yellowing and anti-impact; the surface layer adopts the formula specially prepared by our company: GPPS, matting powder, anti-scratch agent, anti-UV masterbatch, antioxidant, HIPS, the main feature is to increase wear resistance on the basis of anti-yellowing and impact resistance, and at the same time reduce its reflectivity, so that the outer surface has a matte effect, and enhances its anti-yellowing ability;
