Abstract

The invention relates to an infrared isolation glass composition for preventing ultraviolet radiation. A colorant is added to ordinary sodium-calcium-silicon glass; the proportion of the colorant is as below: total iron content (Fe2O3) is between 0.3 and 0.9wt%, the content of ferrous iron (Fe<2+>) in total iron is 24-36%, the content of CuO is between 0.1-0.5wt%, the content of CeO2 is between 0.1-0.5wt%, the content of TiO2 is between 0.2-1.5wt%, and the content of MnO is 0-0.02wt%. The glass excellent heat absorbing performance, more than 75% visible light transmittance no more than 24% of the total infrared transmittance, no more than 15% of ultraviolet transmittance, and no more than 42% of the total solar energy transmittance when the glass thickness is at 4mm. The glass not only does not interfere with people's vision, but also has good effects of sun shading, heat insulation and ultraviolet radiation.

Description

technical field [0001] The invention relates to an infrared-insulating and anti-ultraviolet radiation glass composition. The glass does not hinder people's sight, and has good effects of sunshade, heat insulation and anti-ultraviolet radiation, and belongs to the field of glass preparation. Background technique [0002] Sunlight is composed of ultraviolet rays (200nm-380nm), visible light (380nm-760nm) and infrared rays (760nm-2500nm). Ultraviolet rays not only cause damage to the skin, eyes and immune system of the human body, but also cause aging and fading of leather goods, plastics and other objects, affecting the service life of the objects. Infrared rays are the main source of heat, which greatly increases the load on indoor air conditioners and consumes a lot of energy. Therefore, it is necessary to block infrared rays and ultraviolet rays. The higher the blocking rate, the better, that is, the lower the transmittance, the better. [0003] Most of the existing techn...
