Problems solved by technology
The temperature of this kind of glass is 20°C lower than that of ordinary glass, and its productivity is improved under the same conditions, without NO 2 Such toxic and harmful impurities have achieved the purpose of environmental protection and energy saving, but this kind of glass does not have strong absorption of ultraviolet rays and infrared rays, and the light transmittance is low, so it cannot play a good role in anti-irradiation, heat insulation and sound insulation.

Abstract
The invention discloses energy-saving and environment-friendly glass. The energy-saving and environment-friendly glass is manufactured by the following components of, by weight, 50-70% of SiO2, 5-12% of Na2O, 2-8% of K2O, 4-10% of CaO, 5-16% of B2O3, 0.1-1% of Al2O3, 0.1-1% of Fe2O3, 0.5-1.5% of CeO2 and 0.3-1.5% of SnCl2. In a formula of the glass, Na2O and K2O are used as co-solvents, so that high temperature viscosity of the glass is reduced; and the produced glass has high quality. In the formula of the glass, a proper amount of Fe2O3 and SnCl2 is added, so that the glass has very good effects of absorbing ultraviolet rays and infrared rays and preventing radiation. Components of B2O3 and Al2O3 in the formula can well improve stability of the glass structure and realize high transmittance of the glass.
Description
technical field [0001] The invention relates to the technical field of glass, in particular to an optical glass with high light transmittance, radiation resistance, energy saving and environmental protection. Background technique [0002] In recent years, with the rapid development of our country's economy, the automobile and construction industries have also developed rapidly. However, the harmful gases emitted by heavy industries have caused increasingly serious damage to the ozone layer, the intensity of ultraviolet radiation has increased, and the luxury decoration in automobiles and buildings has been increasingly damaged by ultraviolet radiation. . In summer, cars and buildings are affected by the near-infrared rays of sunlight, and the temperature is high, which greatly increases the load of air conditioning and consumes a lot of energy. Glass is an indispensable building material in our life. With the continuous improvement of the quality of life, in order to build ...
