Problems solved by technology

However, the performance of UV curing glass protective inks currently on the market is immature, because there is a contradictory relationship between the wear resistance and adhesion of protective inks and the release properties of lye, that is, protective inks with good abrasion resistance and adhesion It is not easy to remove the film, difficult to clean, and the ink will fall off in pieces during the process of removing the film, which will cause hangers and blockage of the drain pipe during mass production of protective ink, which will consume a lot of production time and increase manpower and material costs.

Abstract

The invention discloses a UV curable glass protective ink and a preparation method thereof. The protective ink comprises the following components: 40-60 parts of trifunctional polyurethane acrylic resin, 10-15 parts of monofunctional UV-curable monomer , 10-15 parts of aluminum oxide, 8-12 parts of photoinitiator, 2-3 parts of diamino silane coupling agent. The protective ink has strong wear resistance, excellent adhesion, short release time and no residue; it releases the film in small fragments, will not hang on the hanger, will not block the drain pipe, and improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a UV curing glass protection ink and a preparation method thereof. Background technique [0002] At present, capacitive screens have been widely used in the global touch screen market. Compared with the previous resistive screens, they are more practical and have higher technological content. The future will also become a touch era! Customers have increasingly strict requirements on the production quality of touch screen glass lenses. However, there is a common phenomenon in this industry-glass scratches. The straight-through rate of lens production and processing is basically about 50-55%, and the main reason for the defect is the scratch of the lens glass during processing. The re-polishing and grinding of the scratched lens makes the production efficiency lower, and the expensive grinding equipment makes many businesses discouraged. How to reduce glass scratches and improve th...
