Abstract

The invention discloses a multi-layer co-extrusion composite light diffusion plate and a preparation method thereof. The multi-layer co-extrusion composite light diffusion plate comprises flexible diffusion master batch PC material layers, flexible PMMA material layers, high-elasticity light diffusion PET material layers and high-temperature-resistant light diffusion PC material layers, the flexible PMMA material layers are arranged on the two sides of the flexible diffusion master batch PC material layers, the high-elasticity light diffusion PET material layers are arranged on one side of the flexible PMMA material layers, and the high-temperature-resistant light diffusion PC material layers are arranged on one side of the high-elasticity light diffusion PET material layers. The bending performance of the whole composite light diffusion plate can be basically provided through the flexible diffusion master batch PC material layer, and the bending performance of the composite light diffusion plate can be further guaranteed through the flexible PMMA material layer; the elasticity of the composite light diffusion plate can be guaranteed on the basis of the bending performance through the high-elasticity light diffusion PET material layer, the high-temperature resistance of the whole composite light diffusion plate can be guaranteed through the high-temperature-resistant light diffusion PC material layer, and the performance of the plate can be improved to the maximum extent through composite manufacturing of various materials.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a multi-layer co-extruded composite light-diffusing plate and a preparation method thereof. Background technique [0002] Multi-layer co-extrusion composite light diffusion plate is a kind of plastic product commonly used in modern society. It has a very large space for use in terms of scope and method of use. In the existing technology, the thickness of the composite light diffusion plate in the market is less than 1mm Between ~10mm, the light transmittance is between 5% and 85%, and the haze range is between 85% and 95%. Due to the characteristics of the material itself and the factors of the material ratio, the compound light diffuses after the thickness exceeds a certain range. The light transmittance of the plate will be greatly reduced. In order to ensure the light transmittance, haze and plate color requirements of the composite light diffusion plate itself, in order to s...
