Abstract

The invention provides tempered glass which is prepared from novel glass in a chemical tempering manner. The novel glass is prepared from, by weight, 50-80 parts of sodium silicate granules, 30-50 parts of potassium silicate granules, 10-20 parts of anorthite, 15-25 parts of quartz sand, 7-12 parts of graphene, 5-12 parts of aluminum oxide, 3-8 parts of cerium oxide, 2-6 parts of niobium oxide, 10-15 parts of hydrated lime, 2-5 parts of clarifying agents, 1-3 parts of ultraviolet light absorbers and 2-4 parts of 2-4 parts of impact modifiers. The tempered glass is simple and convenient in production process, and the prepared tempered glass has good abrasion resistance, impact resistance, wind pressure resistance, temperature difference resistance, good application prospects and the like.

Description

Technical field [0001] The invention relates to the technical field of glass processing, in particular to a tempered glass. Background technique [0002] Glass has excellent physical and chemical properties, high compressive strength, high hardness, transparency, good stability, and resistance to deformation. It is a widely used inorganic non-metallic material. With the development of science and technology, the application range of glass has become wider and wider, and the requirements for the strength of glass have become higher and higher. Tempered glass is a kind of safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, shock...
