Problems solved by technology

[0004] Heat reflective glass reduces the transmittance of short-wave and long-wave radiation in sunlight while reducing the transmittance of visible light, which causes an increase in heating energy consumption in winter. The biggest disadvantage of this kind of glass is that it will cause light pollution to the outside

Description

technical field [0001] The invention belongs to the field of glass materials, in particular to a nano transparent scratch-resistant glass and a preparation method thereof. Background technique [0002] Glass can be divided into oxide glass and non-oxide glass according to its main components. The main component is silicon dioxide. Silicon dioxide is widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, Construction, chemical, plastic, rubber, abrasive and other industries. [0003] Zirconium dioxide has excellent thermal and chemical stability, and has the characteristics of high melting point, high boiling point, small thermal conductivity, high hardness, good wear resistance, insulator at room temperature, and high refractive index. [0004] Heat reflective glass reduces the transmittance of short-wave and long-wave radiation in sunlight while reducing the transmittance of visible light, which causes an increase in heating en...
