preparation example Construction

[0029] A method for preparing a cover glass of an embodiment of the present invention, comprising the following steps: the glass is placed in the glass reinforcing liquid, soaked in 60 ° C ~ 90 ° C conditions for 20min ~ 180min.

[0030] In a specific example, the preparation method of the cover glass further comprises the following steps: the glass soaked by the glass reinforcing liquid is cleaned with an acidic cleaning solution, and then placed in a protective solution, soaked in 50 ° C ~ 80 ° C conditions for 10min ~ 60min. Wherein, the solvent of the protective liquid is water or ethanol, and the solute includes one or more of the following components: ethyl orthosilicate, silane coupling agent, aqueous glass and alkoxy silicone compounds. After the glass is corroded by an alkaline solution, the newly generated glass surface is not scratch resistant, and the problem of poor scratches may increase, so by soaking in the protective solution, a layer of SiO can be formed on the g...

Abstract

The invention relates to a glass reinforcement liquid, a cover glass, a preparation method thereof, and a display device. The glass reinforcement liquid comprises the following components in terms of mass percentage: 8% to 50% of an alkaline agent, and 0.5% to a weak acid salt additive 3%, anionic surfactant 0.3%~2%, cationic surfactant 0.3%~2%, zwitterionic surfactant 0.3%~2%, nonionic surfactant 0.3%~2%, water is the balance . The glass reinforcing liquid of the present invention uses a certain concentration of alkaline solution to have a shallow chemical reaction with the glass surface, and thins the glass by corroding the glass surface layer. The cleaning effect of surfactants and non-ionic surfactants can dissolve the insoluble silicates generated by the surface reaction, so that the reaction can continue. When the reaction depth is greater than or equal to the micro-crack depth, it can achieve the effect of enhancing the surface strength of the glass. .
