Embodiment 1

[0032] see figure 1 , shows the first decorative sheet in the first embodiment of the present invention, including a transparent substrate 300, an optical nanofilm 200 disposed on the transparent substrate 300, and an optical nanofilm disposed on the optical nanofilm 200 Ink layer 100, a surface of the transparent substrate 300 is provided with micro-nano textures (not shown), the optical nano-film 200 is plated on the micro-nano textures, and the optical nano-film 200 is a multilayer structure, the optical nano film 200 at least includes a color-changing layer 500 that can change the color of the decorative sheet, the thickness of the color-changing layer 500 is 150-600nm, the light after the action of the color-changing layer 500 passes through the micro-nano texture Afterwards, through the transparent substrate 300 , a three-dimensional effect is displayed.

[0033] In this application, the color changing layer 500 is WO 3 layer, using nano-WO 3 (tungsten oxide) as mater...

Embodiment 2

[0047] see Figure 5 , shows the method for manufacturing a decorative sheet in the second embodiment of the present invention, the method includes steps S1-step S4, specifically as follows:

[0048] S1. Obtain the transparent base material of the semi-finished product;

[0049] S2. Embossing micro-nano textures on a surface of the transparent substrate;

[0050] Firstly, the base material of transparent semi-finished products is processed by ordinary glass or transparent resin material, and then the required micro-nano texture is embossed on the upper surface of the base material through micro-nano imprinting technology. The micro-nano texture is relatively fine and the size It can reach about 0.075×0.035×0.015nm. When the visible light is irradiated on the surface of the substrate with micro-nano texture, the displacement and connection will occur when the reflected light is generated, so that the direction and angle of the reflected light will be displaced and connected t...

Abstract

The invention provides a decorative sheet and a manufacturing method of the decorative sheet. The decorative sheet comprises a transparent base material, an optical nano-film arranged on the transparent base material and an ink layer arranged on the optical nano-film, wherein micro-nano textures are arranged on one surface of the transparent base material, the optical nano-film is plated on the micro-nano textures, and the optical nano-film is of a multi-layer structure. The optical nano-film at least comprises a color changing layer, wherein the color changing layer can change the color of the decorative sheet, the thickness of the color changing layer is 150nm to 600nm, and light rays which are processed by the color changing layer pass through the micro-nano textures and then penetrate through the transparent base material to be displayed in a three-dimensional effect. According to the decorative sheet and the manufacturing method of the decorative sheet, the color changing layer is arranged in the decorative sheet, and therefore the decorative sheet can be changed to be in different colors according to different illumination intensities, the dynamic color changing effect is achieved, the decorative colors are rich, the technical scheme of the single decorative color in the traditional technology is replaced, and the technical problem that in the prior art, a decorative sheet is relatively single in decorative color and lacks a three-dimensional decorative effect is solved.

Description

technical field [0001] The invention relates to the technical fields of cover plate decoration and display of electronic products, in particular to a decorative sheet and a manufacturing method. Background technique [0002] With the improvement of living standards, while people are pursuing the use function of products, the decorative effect of products has also attracted more and more attention. [0003] The decorative sheet can be applied to home appliances such as TVs, refrigerators, and air conditioners, or external materials of electronic devices such as smartphones and tablets, so as to exhibit desired colors and patterns. Decorative sheets usually consist of a film such as high-temperature-resistant polyester film (PET) as the base layer, a pattern layer for displaying various patterns, a printing layer for displaying colors, a vapor deposition layer for displaying color and metallic effects, and an adhesive layer. layers etc. Its structure can be modified in vario...
