Abstract

The invention relates to the technical field of coated glass, and particularly relates to a temperable glass product coated with a low-emissivty coating. The glass product comprises a glass substrate layer and a coating layer, wherein the coating layer comprises a Si3N4 layer, a NiCr layer, an Ag layer and a TiO2 layer. The glass product has relatively high transmittance on a visible wavelength; good natural lighting can be ensured; and transmission of solar radiation, especially transmission of near infrared radiation, can be effectively limited, and thus the condition that the coating has good wear-resisting and scratch resistant characteristics, and excellent acid and alkali resistant and corrosion resistant characteristics are ensured; and relatively low light reflectivity, relatively small light pollution, enhanced oxidation resistance and relatively long antioxidant time under the same visible light transmittance rate and radiation are ensured.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a temperable glass product coated with a low-radiation coating. Background technique [0002] A variety of coated glass products have appeared on the market, but the coating materials used in these coated glass products cannot withstand high temperatures. For glass that needs to be tempered, the coating process must be carried out after tempering. For some glass with special shape requirements, it is shaped into a curved surface after tempering, and it is difficult to ensure a uniform film layer when coating curved glass. In addition, because the tempering process of the glass must be carried out after being cut to the required size, when the tempered glass is coated, the glass on the work table is also placed according to the cut size. In this way, those irregularly shaped glasses make the loading rate of the work surface low and the coating efficiency is also very low. [0003]...
