However, the existing optical plate 10 only laminates the photocatalyst layer 14 and the scratch-resistant and wear-resistant layer 16 on the surface of the substrate 12 sequentially through the adhesive 18, so that the photocatalyst layer 14 is easily covered by the scratch-resistant and wear-resistant layer 16, thereby reducing the The self-cleaning property of the optical plate 10, in addition, when the optical plate 10 is used outdoors for a long time, causing the adhesive to age due to exposure to the atmospheric environment for a long time, it is easy to cause the photocatalyst layer 14 and the scratch-resistant wear-resistant layer 16 to fall off, making the The optical plate 10 loses self-cleaning property and scratch resistance

Embodiment Construction
[0014] The following briefly describes the content of the accompanying drawings used in conjunction with the embodiments of the present invention, wherein, figure 2 It is a schematic cross-sectional view showing a long-acting self-cleaning optical sheet according to a preferred embodiment of the present invention.
[0015] Please refer to figure 2 , the long-acting self-cleaning optical sheet 20 provided by a preferred embodiment of the present invention mainly includes a substrate 30 , a plurality of photocatalyst particles 40 , and a plurality of scratch-resistant and wear-resistant particles 50 .
[0016] The substrate 30 is a thermoplastic plastic sheet, such as a transparent optical sheet, or a translucent / opaque optical sheet. The aforementioned translucent / opaque optical sheet can be obtained by adding a diffusing component inside the transparent optical sheet, or by kneading it with a masterbatch. The substrate 30 can be made of polyethylene terephthalate (PET), po...

Abstract
The invention relates to a long-lasting self-cleaning optical plate. The long-lasting self-cleaning optical plate mainly comprises a substrate, a plurality of photocatalyst particles and a plurality of scrape-resisting and wear-resistant particles, wherein the photocatalyst particles and the scrape-resisting and wear-resistant particles are partially embedded into the top surface of the substrate. Therefore, the photocatalyst particles and the scrape-resisting and wear-resistant particles of the long-lasting self-cleaning optical plate can be exposed, and the long-lasting self-cleaning optical plate has relatively good self-cleaning performance and scrape and wear resistance. Due to the special design of embedding, a part of adhesive is coated among the substrate, the photocatalyst particles and the scrape-resisting and wear-resistant particles, and is not directly contacted with an atmospheric environment, a bonding layer is not easy to age, the functional particles do not fall off after a long time, and the self-cleaning performance and the scrape and wear resistance of the optical plate are effectively prolonged.
Description
technical field [0001] The present invention relates to an optical sheet, in particular to a long-acting self-cleaning optical sheet with better self-cleaning properties and anti-scratch and abrasion resistance. Background technique [0002] Plates for outdoor use, such as those used for advertising signs or light boxes, are in contact with the environment for a long time, so that pollutants are easily attached to their surfaces, reducing their service life. In order to solve this problem, a photocatalyst layer with titanium dioxide as the main component is usually coated on the substrate surface of the plate, so that when it is used outdoors, the contaminants attached to the surface can be removed by the flushing of rainwater to achieve self-cleaning. In addition, in order to improve the scratch resistance of the board, a scratch-resistant and wear-resistant layer mainly composed of silicon dioxide is usually coated on the surface of the substrate. figure 1 Shown is an exi...
