Abstract

The invention discloses a deplating solution for removing strong-acid-etching-resistant glass protection ink, a deplating process, deplated glass and electronic equipment, and relates to the technicalfield of glass protection oil removal. The deplating solution for removing the strong-acid-etching-resistant glass protection ink comprises the following components in percentage by mass: 8-12% of asoluble alkali metal hydroxide, 15-25% of ethylene glycol phenyl ether, 6-12% of ethylene glycol monoethyl ether, 0.2-1% of a nonionic surfactant, 0.1-0.5% of octenyl succinic anhydride, 6-12% of an ethanolamine compound and the balance of water. Preferably, in the deplating process, hydrofluoric acid-resistant protective oil on glass is removed by using the deplating solution, and then impurities, intractable small white points and other dirt on the glass are removed by using a deplating solution B. By adopting the deplating solution and the deplating process disclosed by the invention, the protective oil, impurities and intractable small white spots can be effectively removed, the deplated glass is clean and transparent, no damage or scratch is caused, and the deplating time is short.

Description

technical field [0001] The invention relates to the technical field of glass protection oil removal, in particular to a deplating solution for removing strong acid etching-resistant glass protection ink, a deplating process, and glass and electronic equipment after deplating. Background technique [0002] With the continuous development and popularization of smartphones and mobile devices with curved screens, mobile phone screens or back covers with anti-glare frosting effects (Anti-glare, AG effects) are gradually sought after by consumers, especially those with pattern effects and The glass screen with AG effect is especially popular with consumers. In order to achieve the AG effect, it is necessary to use high concentration of hydrofluoric acid to etch the glass surface, which requires a protective glass protection ink to protect the screen during glass processing. Protect the glass surface. [0003] In the prior art, screen printing is usually used to coat the glass pro...
