Ultraviolet scratch-resistant and thermal insulation glass

Abstract

The invention relates to an ultraviolet scratch-resistant and thermal insulation glass which comprises a glass substrate, wherein an ultraviolet-proof coating and a thermal-protective coating are respectively arranged on the upper surface and the lower surface of the glass substrate, the thermal-protective coating comprises the following components: 1.4 parts of styrene, 5.2 parts of calcium metasilicate, 5.4 parts of allyl heptanoate, 5.6 parts of methacrylic acid isocyanide acyl ethyl ester, 6.6 parts of a thickener, 3.7 parts of powdery aluminium hydroxide, 2.5 parts of chloroethylene, 7.8 parts of water and 0.5 part of a surfactant. The thermal-protective coating is prepared from the following raw materials: 25-40 percent of a film forming matter, 15-30 percent of silicon dioxide, 5-10 percent of zinc oxide, 1-3 percent of a dispersing agent, 1-3 percent of a defoamer, and the balance of a solvent. The ultraviolet scratch-resistant and thermal insulation glass provided by the invention is better in thermal insulation performance, and can effectively prevent ultraviolet ray erosion.

Description

technical field [0001] The invention relates to an ultraviolet scratch-resistant heat-insulating glass, which belongs to the technical field of glass. Background technique [0002] Glass is a transparent semi-solid and semi-liquid substance, which 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 cause damage to the human body.
