Bendable light and thin tempered glass and preparation method thereof

Abstract

The invention discloses bendable light and thin tempered glass and a preparation method thereof. The preparation method of the bendable light and thin tempered glass comprises the following steps of (1) embedding nano Al2O3 into a sulfur-containing hyperbranched polysilane and mercaptan silicon resin cross-linked fine net-shaped structure by utilizing hydrogen bonding force between a silanol groupand the nano Al2O3 to obtain a transparent flexible resin film, and taking the transparent flexible resin film as a substrate to effectively absorb impact and prevent the generation of glass cracks;(2) designing and preparing meltable glass, and effectively enhancing the adhesive force between the resin film and the meltable glass by using a hot melting process to inhibit the generation and thediffusion of the cracks; releasing the nano Al2O3 to enter the glass, so that gaps are filled, and the strength of the glass is enhanced; promoting the chemical exchange of sodium ions and potassium ions on the surface of the glass, so that the toughening effect is enhanced, and the wear resistance of the glass is improved; and (3) by means of a spraying method, homogenizing the potassium ion andsodium ion exchange process, so that the problem of non-uniform stress is avoided, and the performance of the bendable light and thin tempered glass is improved.

Description

technical field

[0001] The invention relates to the technical field of tempered glass, in particular to a bendable light and thin tempered glass and a preparation method thereof. Background technique

[0002] Tempered glass is a kind of glass with compressive stress on the surface. It is generally tempered by thermal strengthening, physical strengthening, and chemical strengthening to enhance the strength of the glass and compensate for the brittleness of the glass. However, general high-temperature heat treatment and physical strengthening are not suitable for thin and light glass, while chemical strengthening has nothing to do with size and thickness and is suitable for thin and light tempered glass.

[0003] In general, the thinner the glass, the more bendable it is. In the existing bending, light and thin tempering preparation process, the glass is generally prepared by etching and other methods, and the glass is used as a substrate and coated with a polymer to increase...
