Stable toughened glass

Abstract

The invention relates to a stable toughened glass, which is prepared from the following raw materials by weight: 3-6 parts of sludge, 9-16 parts of feldspar, 4-7 parts of fluorite, 3-8 parts of selenium powder, 7-11 parts of quartz sand, 3-9 parts of barium carbonate, 6-10 parts of niobium carbide, 7-12 parts of calcium sulfide, 5-8 parts of nano-titanium dioxide, 8-13 parts of nano-ferrum dioxide, 6-8 parts of silicon oxide, 2-7 parts of sodium hydroxide, 2-5 parts of triethylamine, 1-5 parts of sodium silicate, 5-10 parts of antimony trioxide, 4-9 parts of ascharite, and 5-10 parts of calcium aluminate. The stable toughened glass provided by the invention has the characteristics of stable performance, wide range of temperature adaptation, also good lightness and hardness, and low self-explosion.

Description

technical field [0001] The invention relates to a stable tempered glass. Background technique [0002] Tempered glass is obtained by cutting ordinary annealed glass into the required size, then heating it to about 700 degrees close to the softening point, and then cooling it quickly and uniformly. 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. Wind pressure, cold and heat, impact, etc. However, the existing tempered glass cannot meet the requirements of use, and there is often a phenomenon of self-explosion. Therefore, people expect to obtain tempered glass with better performance. Contents of the invention [0003] In view of the deficiencies of the prior art, the problem to be solved by the present invention is to provide a stable tempered glass with stable performance, wide temperature range, good lightness and hardness, an...
