Problems solved by technology

However, as 3D cover glass becomes a trend, due to the 3D characteristics of glass, the coating method of screen printing is no longer suitable for the needs of the process. After exploring the process by cover glass manufacturers, it is agreed that spraying can solve the problem of 3D cover glass. The coating method of plate glass frame ink is the spray coating method, which is to coat the entire page of the 3D cover glass, unlike the screen printing coating method, which can form a predetermined pattern

Embodiment 4

[0179] Examples 4 and 5 illustrate the strengthening of chemical resistance, water boiling resistance, and solvent resistance after adding epoxy compounds. Example 6 illustrates the enhancement of yellowing resistance after addition of antioxidant, UV absorber. Example 7 illustrates that after adding a monomer having a fluorene skeleton ethylenically unsaturated group, drug resistance and water boiling resistance are enhanced. Embodiment 8 and embodiment 9 are to add coloring agent and carry out toning.

Abstract

Negative photosensitive white ink for 3D cover plate glass and a preparation method and application method thereof are provided. The negative photosensitive white ink for 3D cover plate glass comprises a white pigment, alkali-solvable resin, a monomer containing ethylene unsaturated groups, a photopolymerization initiator, a solvent, a coupling sealant, and isocyanate compounds. By spraying the ink to 3D cover plate glass and using exposure-development process, a white shade pattern having good film thickness, high resolution, high reflectivity and good shading property can be formed. A pattern formed via the ink is rarely suffered from yellowing, stripping, line breakage or the like.

Description

technical field [0001] The invention belongs to the field of 3D cover glass frame ink, and in particular relates to a negative photosensitive white ink for 3D cover glass and a preparation method and a use method thereof. Background technique [0002] Mobile devices such as smartphones and tablets have continued to grow rapidly in popularity in recent years. The upper border of the mobile device cover glass needs to use various colored border inks. The type and composition of ink have a significant impact on the effect when used on 3D cover glass. It is of great significance to develop inks that are suitable for 3D cover glass and have good effects when used. [0003] In addition, in the past, 2D and 2.5D flat cover glasses were almost all coated by screen printing, and the frame inks of various colors were coated on them, and then thermally cured. However, as 3D cover glass becomes a trend, due to the 3D characteristics of glass, the coating method of screen printing is ...
