preparation example Construction

[0024] The first aspect of the present invention provides a method for preparing impact-resistant tempered glass, wherein the method includes: contacting the tempered glass with silicone oil, then cleaning the glass with the solution, and drying it.

[0025] In the present invention, silicone oil forms a silicon-oxygen film on the surface of tempered glass, which is similar to the Si-O tetrahedral skeleton structure in glass, and can fill the microcracks on the glass surface to heal the microcracks on the glass surface, eliminating Fractured layer on glass surface. Improve the impact strength of glass.

[0026] In the present invention, the contacting method may be but not limited to the dipping method.

[0027] In the present invention, the temperature of the silicone oil may be 150-300°C.

[0028] In the present invention, the tempered glass may be in contact with the silicone oil for 0.5-2 hours.

[0029] In the present invention, the tempered glass is tempered sodium al...

Abstract

The invention relates to the field of glass processing, and discloses anti-impact tempered glass, a preparation method of the anti-impact tempered glass and a display terminal. The preparation methodof the anti-impact tempered glass comprises the following steps of enabling tempered glass to be in contact with silicon oil; then, cleaning glass by a solution; performing drying. The anti-impact glass prepared by using the method has the advantages that on the basis of not influencing the light transmission rate of the glass, the tempering performance and the anti-impact performance of the glasscan be improved; the preparation method is simple and convenient; the raw material cost is low.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to impact-resistant tempered glass, a preparation method thereof, and a display terminal. Background technique [0002] With the gradual promotion of notebook computers and mobile phones, in order to increase the touch feeling and surface aesthetics, the touch panel has gradually evolved from the previous PC material to the current glass material. The demand for ultra-thin glass used in touch panels is also rapidly increasing. The touch method puts forward higher requirements for the strength and hardness of the glass, but the strength and hardness of ultra-thin glass cannot meet the requirements of touch technology for touch screen performance. The surface hardness of the material is relatively high, and the transmittance and anti-scratch effect are quite good. But the property of being easily broken by impact is the fatal property of glass. In order to change the brittle properti...
