Embodiment 1

[0054] Weigh and mix the raw materials (grams) according to the following proportions, and then make the hydrolyzable UV protective ink after mixing.

[0055] Weigh and mix ingredients (grams) in the following proportions:

[0056] 36 grams of modified silicone acrylic resin, 10 grams of modified epoxy acrylic resin, 9.18 grams of isobornyl acrylate, 10 grams of trimethylolpropane triacrylate, 6 grams of chlorinated rubber, 10 grams of grass green pigment, silane 5 grams of coupling agent, 0.3 grams of polyether defoamer, 0.5 grams of modified polyether leveling agent, 0.02 grams of 501 polymerization inhibitor, 9 grams of calcium carbonate, and 4 grams of 369 photoinitiator.

[0057] A hydrolyzable UV protective ink can be prepared. The UV protective ink is printed on the surface of the cover glass and the ITO glass respectively by silk screen printing, and the UV protective ink is cured by ultraviolet lamp irradiation for 30 seconds to form a protective film on the glass s...

Embodiment 2

[0060] Weigh and mix raw materials according to the following proportions to prepare hydrolyzable UV protective ink.

[0061] Modified silicone acrylic resin 36 grams, modified epoxy acrylic resin 15 grams, isobornyl acrylate 5 grams, trimethylolpropane triacrylate 15 grams, chlorinated rubber 5 grams, grass green pigment 7 grams, silane 2.68 grams of coupling agent, 0.3 grams of defoaming agent, 1 gram of leveling agent, 0.02 grams of polymerization inhibitor, 10 grams of calcium carbonate, and 3 grams of 369 photoinitiator.

Embodiment 3

[0063] Weigh and mix raw materials according to the following proportions to prepare hydrolyzable UV protective ink.

[0064] 48 grams of modified silicone acrylic resin, 6 grams of modified epoxy acrylic resin, 10 grams of isobornyl acrylate, 10 grams of trimethylolpropane triacrylate, 5 grams of chlorinated rubber, 7 grams of grass green pigment, silane 2.68 grams of coupling agent, 0.3 grams of defoaming agent, 1 gram of leveling agent, 0.02 grams of polymerization inhibitor, 5 grams of calcium carbonate, and 5 grams of 369 photoinitiator.

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...
