Description
Technical Field
The invention relates to the field of glass processing, in particular to impact-resistant toughened glass, a preparation method thereof and a display terminal.
Background
With the gradual popularization of notebook computers and mobile phones, in order to increase the touch feeling and the surface aesthetic property, the touch panel is gradually changed from the conventional PC material to the conventional glass material. The demand of the ultrathin glass adopted by the touch panel is rapidly increased, the touch mode puts forward higher requirements on the strength and the hardness of the glass, but the strength and the hardness of the ultrathin glass cannot meet the requirements of the touch technology on the performance of the touch screen, the surface hardness of the glass material is higher, and the transmittance and the scratch-resistant effect are good. But the characteristic of being easily broken by impact is the deadly characteristic of glass. In order to change the brittle nature of glass when subjected to impact, chemical tempering processes have been developed.
The reinforcement of ultra-thin glass is mainly achieved by chemical tempering. The glass is subjected to a series of processing processes such as cutting, grinding, polishing and the like before chemical tempering, the processed glass surface or subsurface has more or less micro cracks, and the depth, length, width, quantity and distribution of the micro cracks on the glass surface and the scratch and abrasion of the glass surface have great influence on the glass strength, particularly the impact strength of the glass.
The chemical strengthening is to soak the glass in a potassium nitrate solution, and to replace sodium ions on the surface of the glass with potassium ions in the potassium nitrate solution for a long time and at a high temperature, so that a replacement layer of potassium and sodium ions is formed on the surface of the glass, and the glass generates certain internal stress, commonly called surface stress value. The chemically strengthened glass can be used as touch screen glass (including OGS, In-Cell, On-Cell, G/G, G/F, G/F/F) of electronic devices such as smart phones, tablet computers, ultrabooks and the like.
However, the impact resistance effect of the glass formed by the existing chemical tempering is not good, for example, in a steel ball experiment: the glass is crushed by freely falling from the height of 500mm by using a steel ball with the diameter of 30mm and the weight of 120g, and the strength of the glass after chemical tempering is not high, namely the impact strength can not meet the test requirements of people.
In order to solve the problem of poor impact resistance, CN104400581A discloses a method for performing fine polishing on tempered glass to remove microcracks on the surface of the tempered glass, but because both sides of the tempered glass have large compressive stresses symmetrically distributed along the thickness direction, if the fine polishing process is not proper, the removal thicknesses of both sides of the glass are inconsistent, and the stress distribution of both sides of the processed glass is asymmetric, so that the glass is deformed or even broken, thereby greatly reducing the yield of the glass.
CN103508674A discloses a method for removing micro-cracks on the surface of tempered glass by etching with hydrofluoric acid, but the method has the disadvantages of environmental pollution, dangerous operation, corrosion of the glass surface by the external environment after acid treatment, reduced surface hardness and ineffective strength maintenance.
CN102643033A discloses coating the surface of toughened glass with an organic glue layer and subjecting it to a high temperature treatment, said organic glue layer being converted into a protective layer, thereby improving the impact resistance. Although the organic glue layer has simple manufacturing process and low cost, the organic glue layer is easily influenced by the external environment, and once the organic glue layer is damaged, the glass strength is obviously reduced.
