Abstract

The invention discloses chemically-tempered glass and a preparation method. The chemically-tempered glass comprises quartz sand, kaolin, dolomite, barium oxide, feldspar, potassium chloride, a clarifier, molybdenum trioxide, magnesium oxide, ethylenediamine tetraacetic acid disodium salt, tetraethoxysilane, potassium permanganate, ammonium zirconium carbonate and triethanolamine. The preparation method comprises steps as follows: (1) mixing and grinding and (2) forming. The production process of the chemically-tempered glass adopts a physical tempering method which is simple and easy to implement, so that the finally obtained chemically-tempered glass is good in safety, has remarkably improved bending strength and impact strength, high flatness, particularly, arc edge flatness, excellent thermal stability and good appearance quality. Compared with ordinary glass, the tempered glass has the bending strength improved by 2.5-6.0 times, the compressive strength improved by 2.5-4.8 times and the impact strength improved by 3.6-8.5 times and meets the demands of building and decoration markets.

Description

technical field [0001] The invention relates to tempered glass, in particular to a chemically tempered glass and a preparation method. Background technique [0002] Tempered glass is a kind of prestressed glass, which is obtained by processing annealed glass into required size and shape, heating to softening point at high temperature, and then quenching. Tempered glass has high mechanical strength, impact strength, and bending strength, and has good safety and thermal stability. It is currently the most commonly used form of safety glass. Chemically tempered glass is a kind of tempered glass, which is obtained by heating flat glass close to the softening point of the glass, and then immediately sending it into a bending die for forming, and then quenching and cooling after forming. Due to the special properties of chemically tempered glass, it has a wide range of uses, and can be used for high-rise buildings, safety decorative glass for various buildings, window glass for v...
