Nanometer transparent heat-protecting glass and manufacturing technology thereof

Abstract

The invention provides nanometer transparent heat-protecting glass and a manufacturing technology thereof and relates to the technical field of glass manufacturing. The nanometer transparent heat-protecting glass is mainly prepared from the following ingredients in parts by weight: 50 to 60 parts of silicon dioxide, 12 to 15 parts of sodium silicate, 7 to 13 parts of borax, 3 to 5 parts of calcium metasilicate, 0.05 to 0.2 part of arsenious oxide, 0.3 to 0.7 part of zinc oxide, 1 to 3 parts of magnesium carbonate, 0.2 to 0.4 part of zirconium sulfate, 0.2 to 0.4 part of calcium fluoride, 0.5 to 1 part of potassium feldspar, 0.3 to 0.5 part of ethylchlorosilane, 0.03 to 0.05 part of tungsten trioxide and 0.02 to 0.08 part of cobaltous oxide. The nanometer transparent heat-protecting glass is further prepared from the following ingredients in parts by weight: 0.2 to 1 part of nanometer strontium titanate, 0.05 to 1 part of 3,4-dimethylpyrazole phosphate and 0.02 to 0.08 part of yttrium oxide. The nanometer transparent heat-protecting glass provided by the invention has better thermal insulation capacity and higher light transmittance.

Description

technical field [0001] The invention belongs to the technical field of glass manufacturing, and in particular relates to a nano-transparent heat-insulating glass and a manufacturing process thereof. Background technique [0002] Glass is formed by melting silicon dioxide and other chemicals together (mainly produced from: soda ash, limestone, quartz). A silicate-based non-metallic material that forms a continuous network structure during melting, and gradually increases in viscosity and hardens during cooling to cause it to crystallize. The main component of ordinary glass is silica, which has high chemical stability, thermal stability and good transparency, so it is widely used in buildings for wind and light transmission. [0003] Insulating glass is a kind of performance glass, they do not significantly absorb visible light, but absorb a lot of heat-generating near-infrared light. If the glass cannot effectively block the heat of outdoor sunlight from entering the room,...

AI Technical Summary

Problems solved by technology

If the glass cannot effectively block the heat of outdoor sunlight from entering the room, the thermal radiation of the heated glass will increase the temperature in the space, thereby reducing the comfort

Heat-insulating glass tends to absorb short-wave radiation in sunlight, which reduces the transmittance of visible light, thereby affecting the light transmittance of the glass

[0004] At present, the heat insulating glass widely used by people is generally coated heat insulating glass, but the ability of heat removal and high light transmittance cannot be effectively balanced.
