In recent years, the development of touch screen type electronic products is rapid, and the smart phone technology is particularly prominent. With the continuous update and the replacement of intelligent products, the demand of functional glass is increasing, and with the increase of the size of a display screen of a mobile phone, the thickness of the mobile phone is continuously reduced, and the mobile phone glass becomes increasingly thinner, so that the thinning of the mobile phone glass and the touch mode of a touch panel of the mobile phone put forward higher requirements on the strength and the hardness of the glass.
At present, widely used mobile phone glass is single-layer plate glass, microcracks exist on the surface of the processed glass more or less, and the strength of the glass is greatly reduced due to the abrasion, scratch and other flaws on the surface of the glass. In order to improve the impact resistance and the drop resistance of the mobile phone glass, the mobile phone glass is generally subjected to film sticking and glass strengthening treatment. However, the film sticking process on the glass panel is complicated, the cost is increased, the shock resistance is poor, and the glass panel is easy to break and splash due to impact. In addition, the chemically tempered glass has a poor impact resistance, and it has been found through experimental tests that the chemically tempered glass is directly broken when a steel ball with Φ of 32 and M of 130g is freely dropped from a height of 600mm to the chemically tempered glass. That is, the strength of the glass is improved to some extent by the above method, but there is a gap from the desire in the industry for a functional glass having high strength.
Therefore, the development of glasses with higher strength is still an important research direction in the field of glass manufacturing. For thinned glass, applying a coating can be a very effective way to treat the defects. The applicant aims to provide a glass reinforcing liquid which can be coated on the surface of glass to fill the defects on the surface of the glass so as to improve the strength of the glass.
