Problems solved by technology

However, for the screen printing method, due to the structure of the 3D glass, it is difficult to control the film thickness and effect of the printed curved surface when using hyperboloid glass, which affects the pattern accuracy; for the thin film thermal transfer method, Since the sheet film is stretched and deformed and then copied to the curved glass, the pattern will be stretched and the decorative effect will be poor; moreover, this method has high requirements on the mold, and the sheet needs to be heated and softened to be completely attached to the glass.

preparation example Construction

[0043] At the same time, the present invention also provides a method for preparing a 3D decorative glass, the method comprising the following steps: S1, preparing a light-absorbing ink, and spraying it on one side surface of the 3D glass substrate, drying and curing to form a light-absorbing ink layer; S2. Inject laser light from the other side of the 3D glass substrate, etch the light-absorbing ink layer to form a partially hollowed-out decorative ink layer; S3. On the surface of the one side of the 3D glass substrate, fill the part of the decorative ink layer A metal mirror filling layer is formed in the hollow area; S4, forming a black light-shielding ink layer on the surface of the decorative ink layer and the metal mirror filling layer away from the 3D glass substrate.

[0044] The steps of the above-mentioned method provided by the present invention are simple and easy to reproduce, and the laser is used to etch the light-absorbing ink layer attached to the other side of...

Abstract

The invention relates to the field of 3D glass surface decoration, and discloses 3D decorative glass and a preparation method thereof. The 3D decorative glass comprises a 3D glass substrate, a partially hollow decorative ink layer, a metal mirror filling layer and a black shading ink layer, wherein the decorative ink layer is attached to one side surface of the 3D glass substrate, the metal mirrorfilling layer is attached to the other side surface of the 3D glass substrate and filled in the hollow region of the decorative ink layer, and bare surfaces of the decorative ink layer and metal mirror filling layer are covered with the black shading ink layer. A beautiful three-dimensional pattern can be exhibited by the 3D decorative glass, the precision of the exhibited three-dimensional pattern is high, and the boundary between the decorative ink layer and the metal mirror filling layer is clear and substantially has no jags.

Description

technical field [0001] The invention relates to the field of 3D glass surface decoration, in particular to a 3D decorative glass, and also to a preparation method of the 3D decorative glass. Background technique [0002] With the improvement of living standards, consumers have higher and higher requirements for the appearance of electronic products; and 3D glass, which can improve the window effect of electronic products and make them crystal clear and strong in perspective, has been more and more widely used. [0003] At present, the surface decoration methods of 3D glass mainly include screen printing and film thermal transfer printing. The former uses a 300-mesh screen to hollow out the pattern effect and print the ink on it; the latter prints the pattern on PET or PMMA in advance. On the film, put the film sheet into the grinding tool when using it, and heat it to transfer the pattern on the glass. However, for the screen printing method, due to the structure of the 3D ...
