Description

Technical Field

[0001] The invention relates to the field of smart surfaces, and in particular to a method for preparing a cover glass with surface texture and angle-dependent color effects. Background Art

[0002] Cover glass is used as the outermost layer of the touch screen to protect the touch screen due to its advantages such as high light transmittance and strong scratch resistance. In recent years, in order to personalize, intelligentize and overall beautiful products, researchers have used printing technology to print different colors, patterns and signs on glass to decorate and beautify products. Among them, cover glass with angular color-changing decorative effect has attracted much attention because it can present different color effects with different observation angles, showing rich color effects and personalized characteristics. For printing technology, although the angular color-changing effect can be achieved by printing with color-changing inks adding various chameleon pigments, the chameleon pigments are granular. From the analysis of the structural color microstructure, they are essentially short-range ordered structures, resulting in poor angular dependence of color changes and single color changes. In addition, the particle size distribution of chameleon pigment particles is often in the micron range. When added to the paint film, due to the random distribution of its surface roughness, density, particle size, etc., the screen looks uncomfortable with light and dark "flash points".

[0003] In view of the above problems and the shortcomings in the art, the present invention provides a method for preparing a cover glass with surface texture and angle-dependent color effects. The present invention uses a long-range ordered photonic crystal film to bond with a glass cover, and then further bonds a layer of PET film to the surface of the photonic crystal film, and then performs a hot embossing treatment or a coating and a curing treatment after combining the embossed film to further complete the surface pattern construction. Therefore, by adjusting the color or embossed pattern of the photonic crystal film, an angle-dependent color cover glass with different surface textures and different primary colors is developed. Summary of the invention

[0004] 1. Technical problem to be solved by the invention: The object of the present invention is to provide a method for preparing a cover glass with surface texture and angle-dependent color effect, so as to solve the problem that the angle-dependent color effect is achieved by printing with color-changing inks to which various chameleon pigments are added in the above-mentioned background technology, and the surface roughness, density, particle size, etc. are randomly distributed to varying degrees, resulting in the screen appearing to have uncomfortable "flash points" of alternating light and dark.

[0005] 2. Technical solution: To achieve the above object, the present invention provides the following technical solution: a method for preparing a cover glass having a surface texture and an angle-dependent color effect, wherein the processing technology comprises the following steps: A method for preparing a cover glass with surface texture and angle-dependent color effect, characterized in that the process comprises the following steps: S1, glass cover plate processing, including the following sub-steps: S11, cleaning and drying the glass cover to remove surface oil and dirt; S12, after the surface of the glass cover plate is dried, coating the adhesive layer on the glass surface by a coating machine; S13, attaching the photonic crystal film material to one side of the cover glass; S2, forming, including the following sub-steps: S21, applying a film-forming substance (a protective film is formed after the solvent evaporates) on the surface of the laminated composite cover glass through a coating machine, and the protective film can be directly laminated according to needs; S22, then heat embossing the surface of the composite cover glass by a hot press or performing surface pattern construction with the aid of a release embossed film; S23, peeling off the release embossed film to obtain a cover plate with a multi-layer composite structure of surface texture layer-crystal film material-glass.

[0006] Preferably, the cover glass plays a role in protecting the touch screen, and the photonic crystal film material serves as a color decoration layer.

[0007] Preferably, the decorative effect of the composite cover plate color (primary color and colors at different angles) can be adjusted by adjusting the color type of the photonic crystal film material.

[0008] 3. Beneficial effects: Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention creatively develops a method for preparing a cover glass with surface texture and angle-dependent color effects, and its structure includes a texture layer-photonic crystal layer-glass multilayer structure. Among them, the cover glass plays a role in protecting the touch screen, and the photonic crystal film material serves as a color decoration layer. Its appearance has beautiful structural colors, and its internal long-range ordered microstructure gives its color that changes with the observer's observation angle. The outermost layer plays a role in surface protection and pattern construction. By adjusting the color type of the photonic crystal film material, the decorative effect of the composite cover color (main color and color at different angles) can be adjusted; by adjusting the pattern of the hot pressing mold or the release embossed film, the surface texture of the composite cover can be adjusted. The composite structure glass cover has the beneficial effects of angle-dependent color, high transparency, low haze, no flash point, and no color deviation in the display screen, and has great application value in the field of smart surfaces.
