Abstract
The invention discloses a preparation method of high-transmittance tempered low-emissivity coated glass. The preparation method comprises the following steps: setting a glass base plate and plating a titanium oxide dielectric layer, a silicon nitride dielectric layer, a zinc oxide dielectric layer, a nickel-chromium metal alloy layer, a silver functional layer, a nickel-chromium metal alloy layer, a zinc tin oxide dielectric layer and a silicon nitride dielectric layer on the glass base plate in sequence. The preparation method has the benefit that a multilayer film structure is prepared on the surface of a float glass base material through the offline magnetron sputtering technology, so that the glass has relatively high transmittance and selective coefficient and has high reflection for the infrared areas and the emissivity of the glass can be effectively reduced.
Description
technical field [0001] The invention relates to the technical field of glass coating, in particular to a method for preparing toughened low-emissivity coated glass with high transmittance. Background technique [0002] At present, low-E coated glass has been widely used in the construction field, which has the characteristics of low heat transfer coefficient and infrared reflection. The increase of transmittance is generally achieved by the anti-reflection effect of the dielectric layer and the reduction of the thickness of the metal layer. However, if the thickness of the metal layer is too low, it will cause the oxidation of the functional layer during tempering, which will affect the optical properties of the coated glass, thus affecting the coating. Deep processing performance of glass. Contents of the invention [0003] The invention aims to solve the problems of the transmittance of the coated glass and the deep processing of the coated glass. [0004] In order to ...
