Anti-ultraviolet heat-isolating colored glass and production process thereof

Abstract

The invention provides anti-ultraviolet heat-isolating colored glass and a production process thereof and relates to the technical field of colored glass. The glass is prepared from the following rawmaterials in parts by weight: 80-90 parts of silicon dioxide, 2-5 parts of potassium feldspar, 2-5 parts of calcium sulfate, 28-70 parts of calcium carbonate, 24-60 parts of potassium carbonate, 20-30parts of sodium hydrogen carbonate, 10-15 parts of mirabilite, 10-20 parts of sodium carbonate, 15-25 parts of barium carbonate, 5-15 parts of cerium oxide, 5-15 parts of sodium sulfate, 5-10 parts of arsenic trioxide, 10-15 parts of sodium nitrate, 10-12 parts of stannic oxide, 5-10 parts of an ultraviolet screening agent, 5-10 parts of a colorant and 20-30 parts of a heat isolating agent. The production process of the colored glass comprises the following five steps: melting and stirring; mold injecting; annealing; thermal treatment; and cooling and cutting. The colored glass is good in stability, the surface of the glass is unlikely to weather, and the glass is high in strength and good in quality and has the functions of preventing ultraviolet rays and isolating heat. The preparationprocess of the colored glass is simple and is suitable for continuous industrial production.

Description

technical field [0001] The invention relates to the technical field of colored glass, in particular to an ultraviolet-resistant heat-insulating colored glass and a production process thereof. Background technique [0002] Glass is a transparent semi-solid and semi-liquid substance that forms a continuous network structure when molten, and is a silicate non-metallic material that gradually increases in viscosity and hardens during cooling. The main component of ordinary glass is silicon dioxide, which has high chemical stability, thermal stability and good transparency, so it is widely used in various fields. At present, most of the glass widely used by people is single-layer flat glass, which has good light transmission, but the thermal insulation effect is poor, and it cannot effectively block the heat of outdoor sunlight from entering the room, resulting in high indoor temperature and cannot be effectively Block ultraviolet rays, excessive ultraviolet rays can easily caus...
