High-transmittance coated glass coated with compound dielectric layer and compound antireflection layers and production technique thereof

Abstract

The invention provides a high-transmittance coated glass coated with a compound dielectric layer and compound antireflection layers and a production technique thereof. Outwardly from the glass substrate, the high-transmittance coated glass sequentially comprises the following structural layers: a glass / compound antireflection layer (1), a silver layer (1), a protective layer (1) / compound dielectric layer (1), a silver layer (2), a protective layer (2), a compound antireflection layer (2), a silver layer (3), a protective layer (3) and a dielectric layer (1). The coating layers are coated by using a vacuum magnetron sputtering coating technique, have the advantages of extremely strong infrared reflection capability and low emissivity of the coating layer surfaces, have higher sunlight shading performance as compared with the traditional double-silver low emissivity coatings, and achieve favorable glass characteristics, such as high transmittance and medium / low reflectivity for visible light, and the like.

Description

Technical field: [0001] The invention relates to a triple-silver low-radiation coated glass coated with a composite dielectric layer and a composite antireflection layer with high transmission and high efficiency sunshade performance. Background technique [0002] With the continuous pursuit of high transparency of external light and high shading performance of glass curtain walls, the contradiction between the two has become increasingly prominent. There are low-emissivity coated glasses coated with double silver layers on the market. Generally, products with high visible light transmission have a higher shading coefficient. There is no low-emission coated glass with a double-layer silver structure that satisfies both high transmittance and low shading coefficient. Contents of the invention [0003] The purpose of the present invention is to provide a low-emissivity coated glass with high visible light transmittance and low shading coefficient coated with three layers o...
