Abstract

The invention provides semi-tempered vacuum glass, which is obtained by processing high-strength flat semi-tempered glass, wherein the high-strength flat semi-tempered glass is prepared from the following raw materials: sodium silicate granules, a PVC resin, silicon dioxide, aluminum oxide, magnesium oxide, carbon fibers, silicon nitride, borax, basalt, an impact modifier, an antioxidant, an ultraviolet absorbent and polyethylene glycol 4000. According to the invention, the high-strength flat semi-tempered glass prepared by the invention has excellent mechanical properties such as wind pressure resistance, temperature difference resistance, impact strength and the like, is not prone to spontaneous explosion, and is safe and stable; and with the sealing and connecting method, tempered vacuum glass can be prepared at a low temperature, so that the annealing of the tempered glass can be effectively avoided, and the prepared tempered vacuum glass has characteristics of extremely low thermal conductivity, good thermal insulation performance, light weight, small thickness and good application prospect.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to semi-tempered vacuum glass. Background technique [0002] In the vacuum glass structure, two pieces of glass are not ordinary glass but semi-tempered glass, which is called "semi-tempered vacuum glass". Tempered glass has high strength, impact resistance and bending strength 3-5 times higher than ordinary glass, thermal shock resistance is also greatly improved, and after being broken, it will form small particles without sharp blades, which will cause little harm to people. However, due to a variety of complicated reasons, the probability of tempered glass "self-explosion" is relatively high. Studies have shown that, especially when the surface compressive stress is ≥ 52.0MPa, the probability of self-explosion caused by impurities inside the glass is greatly increased. [0003] Since the working temperature of the glass brazing material used for vacuum glass edge and a...
