preparation example Construction

[0049] The present invention also provides the preparation method of the above-mentioned photosensitive ink, comprising the following steps: (1) mixing the alkali-soluble UV resin, quick-drying solvent, UV monomer, photoinitiator, pigment, filler and auxiliary agent uniformly and grinding to obtain the component A; Mix and grind epoxy resin, epoxy curing accelerator, slow-drying solvent, filler and coupling agent evenly to obtain component B; (2) Mix component A and component B in proportion to obtain photosensitive ink. The preparation method of the above-mentioned photosensitive ink is simple and easy, has high yield rate and low cost, and is suitable for mass production. The prepared photosensitive ink is suitable for surface decoration of glass and ceramics, especially surface decoration of multi-curved surfaces.

[0050] Preferably, in the above-mentioned preparation method, the components are mixed while stirring, and the speed of the mixer is 500-1000 rpm. After mixing e...

Embodiment 1

[0056] A preferred embodiment of the present invention provides a photosensitive ink, and the composition of component A and component B is shown in Table 1.

[0057] The composition of photosensitive ink in table 1 embodiment 1

[0058]

[0059]

[0060] The preparation method of the above-mentioned photosensitive ink is as follows: the rotating speed of the mixer is 800 rpm, and the materials in the A component in Table 1 are sequentially added while stirring. Grind on a three-roller machine to a fineness of ≤5μ; the speed of the mixer is 800 rpm, and the materials in component B in Table 1 are added in turn while stirring, and after mixing evenly, disperse at a speed of 2500 rpm for 25 minutes. Then grind on a three-roller machine to a fineness of ≤5μ; mix the above-mentioned component A and component B according to a weight ratio of 5:1 to obtain photosensitive ink.

Abstract

The invention discloses light-sensitive ink and a preparation method and application thereof; the light-sensitive ink comprises component A and component B; the component A comprises alkali-soluble UV (ultraviolet) resin, a quick-drying solvent, a UV monomer, a photoinitiator, a pigment, a filler and an aid; the component B comprises epoxy resin, epoxy curing accelerant, a low-drying solvent, a filler and a coupling agent; the weight ratio of the component A and the component B in the light-sensitive ink is 5:1. The light-sensitive ink is applicable to surface decoration for glass or ceramics, particularly multi-surface glass or ceramics, such as having 2.5D surface and 3D surface; the glass or ceramics that are surface-decorated have good appearance, and images are vivid; the light-sensitive ink has high hardness, adhesion and yield, is low in cost and is applicable to batch production.

Description

technical field [0001] The invention relates to the field of inks, in particular to a photosensitive ink. In addition, the present invention also relates to a preparation method and application of the above-mentioned photosensitive ink. Background technique [0002] With the development of electronic products and the advent of the 5G era, if the casings of electronic products continue to use metal, it will affect the transmission of network signals and cannot meet the requirements of 5G networks. To solve this problem, the front and rear covers of electronic products can be made of plastic, glass, ceramics or sapphire. Among them, electronic products made of plastic are relatively low-grade in appearance and cannot meet people's increasingly high-quality requirements for electronic products; electronic products made of sapphire have a high-grade appearance, but their production costs are high and their yield rate is low. Mass production is not yet possible; thus glass and ...
