Document Type and Number:
WIPO Patent Application WO/2023/173818
Kind Code:
A1
Abstract:
The present invention provides a light diffusion plate capable of being used for a long time, a preparation method therefor and an application thereof. According to the light diffusion plate of the present invention, polystyrene (GPPS) to which a light diffusion agent is added is used to make a light diffusion layer, a protective layer is compounded on each of the upper surface and the lower surface of the GPPS light diffusion layer, the protective layer is an SMA (styrene-maleic anhydride copolymer) resin blending modified PMMA resin layer, and the SMA resin added in the protective layer can achieve a tackifying effect, so that the interlayer bonding force between the two different material layers, i.e., the PMMA resin layer and the GPPS layer, can be effectively improved, thereby significantly prolonging the service life of the plate.
