Embodiment 1

[0029] Add 100 grams (0.61mol) of novolac epoxy resin (NPPN-638S), 0.2 grams of triphenylphosphine, and 0.26 grams of hydroquinone into the reactor, raise the temperature to 110°C, and add 38.2 grams (0.53mol) of AA and 219.5 The mixed solution of gram (1.06mol) AMPS was added dropwise slowly and continuously for 60 minutes with a constant pressure funnel, and after the dropwise addition was completed, it was kept at 115° C. for 2 hours to obtain a novolak epoxy acrylic resin.

[0030] Weigh the following raw materials in parts by weight: 50 parts of phenolic epoxy acrylic resin, 20 parts of 1,6-hexanediol diacrylate, 5 parts of 1-hydroxycyclohexyl phenyl ketone, 15 parts of talcum powder, and 10 parts of barium sulfate , 0.5 parts of defoamer. Mix epoxy acrylic resin with reactive diluent, add photoinitiator, filler, defoamer, and form a uniform viscous liquid after high-speed stirring. Put the viscous liquid into a grinder and grind it to get the finished protective ink.

Embodiment 2

[0032] Add 100 grams (0.61mol) of novolac epoxy resin (NPPN-638S), 0.2 grams of triphenylphosphine, and 0.26 grams of hydroquinone into the reactor, raise the temperature to 110°C, and add 38.2 grams (0.53mol) of AA and 219.5 The mixed solution of gram (1.06mol) AMPS was added dropwise slowly and continuously for 60 minutes with a constant pressure funnel, and after the dropwise addition was completed, it was kept at 115° C. for 2 hours to obtain a novolak epoxy acrylic resin.

[0033] Weigh the following raw materials in parts by weight: 50 parts of novolac epoxy acrylic resin, 20 parts of hydroxypropyl methacrylate, 5 parts of 1-hydroxycyclohexyl phenyl ketone, 15 parts of talcum powder, 10 parts of barium sulfate, defoamer 0.5 servings. Mix epoxy acrylic resin with reactive diluent, add photoinitiator, filler, defoamer, and form a uniform viscous liquid after high-speed stirring. Put the viscous liquid into a grinder and grind it to get the finished protective ink.

Embodiment 3

Abstract

The invention discloses acid resistance type protective ink and a preparation method thereof. Phenolic epoxy acrylic resin which comprises a multi-reaction functional group and a hydrophilic group is synthesized, the screening of filling materials, a defoaming agent and other additives is integrated with the phenolic epoxy acrylic resin as a main body, and the acid resistance type protective ink with the good hydrofluoric acid resistance and the dehydration effect is prepared. According to the acid resistance type protective ink and the preparation method thereof, the superior adhesion is presented on OGS (One Glass Solution) touch screen glass, the time of the resistance to the 20% of hydrofluoric acid can reach more than 30 minutes, the film stripping can be achieved through the ordinary hot water, the harm to the glass is not produced, a protective film falls off in a flaked mode during film stripping, the filtration and the separation are easy, the degree of automation of the process is high, and the safe and environment-friendly effect is achieved.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an acid-resistant protective ink and a preparation method thereof. Background technique [0002] A touch screen is an inductive liquid crystal display device that can receive input signals such as contacts. It is mainly used in smart phones, tablet computers, industrial control and other fields. Under the trend of thinner, lighter and lower cost, one glass solution (OGS for short) touch screen has become the mainstream touch technology in the market. In the hydrofluoric acid strengthening process of the OGS touch screen process, it is necessary to use an anti-hydrofluoric acid film to protect the touch screen circuit. Although the protection performance of the anti-hydrofluoric acid film is superior, the application accuracy is extremely high and the process is complicated. When removing it, each piece of the anti-hydrofluoric acid film needs to be manually removed, and the prod...
