Abstract

The invention discloses temperable off-line net-color high-transmittance silver-free LOW-E coated glass and a preparation method thereof. The preparation method comprises the steps that a first dielectric layer, a second dielectric layer, a functional layer, a third dielectric layer and a fourth dielectric layer are sequentially sputtered on a glass substrate from bottom to top, and the first dielectric layer and the fourth dielectric layer are silicon nitride layers, and the second dielectric layer and the third dielectric layer are silicon oxide layers, the functional layer is an indium tinoxide layer, the thickness of the fourth dielectric layer is larger than that of the first dielectric layer, the thickness of the third dielectric layer is larger than that of the second dielectric layer, and high-vacuum magnetron sputtering coating equipment is adopted for sputtering layer by layer. The visible light transmittance of the film layer is improved through the four dielectric layers,the visible light transmittance of the film layer can reach over 87%, the thickness of the functional layer is large, the anti-radiation capacity is high, and the radiance is lower than 0.1.

Description

technical field [0001] The invention relates to the technical field of low-radiation coated glass, in particular to a temperable off-line clear color high-transparency silver-free LOW-E coated glass and a preparation method thereof. Background technique [0002] LOW-E glass, also known as low-emissivity glass, is a kind of energy-saving glass. With the continuous improvement of the country's requirements for building energy conservation, LOW-E glass has been more and more widely used. However, traditional Low-E glass achieves a good heat insulation effect through silver coating, and the silver layer is easily oxidized when exposed to the air for a long time, causing the film function to fail. Therefore, the storage conditions and conditions of Low-E coated glass The process control of post-processing puts forward very high requirements; it also makes this kind of LOW-E glass cannot be used in a single piece, and the coated glass must be synthesized into insulating glass and ...
