Hydrolyzable UV (ultraviolet) protection ink

Abstract

The invention provides a hydrolyzable UV (ultraviolet) protection ink, which is prepared by mixing the following components in parts by weight: 30-48 parts of modified organosilicon acrylic resin, 6-15 parts of modified epoxy acrylic resin, 5-12 parts of isobornyl acrylate, 10-15 parts of trimethylolpropane triacrylate, 5-12 parts of chlorinated rubber, 7-15 parts of grass green pigment, 2-5 parts of silane coupling agent, 0.1-0.5 part of defoaming agent, 0.5-1.0 part of leveling agent, 0.02-0.04 part of polymerization inhibitor, 5-15 parts of calcium carbonate and 2-8 parts of 369 photoinitiator. The UV protection ink provided by the invention is a hydrolyzable UV curing protection ink of which the curing time can be obviously shortened. In addition, after finishing processing touch screen cover plate glass or ITO glass, the protective film can be removed by soaking in alkaline water. The UV protection ink has the advantage of no residue, can be peeled easily, and thus, has wide application prospects.

Description

technical field [0001] The invention relates to a hydrolyzable UV protective ink, in particular to a hydrolyzable UV protective ink used in the field of touch screen cover glass or ITO glass processing. Background technique [0002] As a high-strength, scratch-resistant glass, touch screen cover glass is widely used in high-end smartphones, tablet computers, flat-panel TVs, and industrial and commercial touch screens. In the field of touch screen cover glass or ITO glass processing, the surface of the touch screen cover glass and ITO glass will be scratched during special processing processes such as opening, edging, and polishing, resulting in a defective rate of up to 99%. %. At the same time, the damaged glass will also increase the subsequent polishing and flat grinding process, thereby increasing the production cost. In order to solve this technical problem, a variety of protective inks have been developed on the market. These protective inks are mainly printed on the...

AI Technical Summary

Problems solved by technology

[0004]1. The ink is solvent-based, and contains a large amount of volatile solvents that pollute the production environment;

[0005]2. The surface of solvent-based ink is easy to dry during the printing process, and the solvent needs to be continuously replenished to maintain good scraper performance, and the operation process is complicated during use;

[0006]3. Existing inks are cured at high temperature with slow speed, so the cost is increased and the process is complicated in use;

[0007]4. After the glass is processed, it is troublesome to remove the protective ink, and the residual glue is easily left on the glass
