Production process of transparent conductive low-radiation glass coating

Abstract

The present invention discloses the production process of transparent conductive low-radiation glass coating. The inorganic compound of tin is used as material in synthesizing one kind of precursor solution for producing transparent conductive low-radiation glass coating on the surface of float glass; and the precursor solution is sprayed to the surface of hot float glass to form doped low-radiation tin oxide layer with required thickness and performance. The present invention has the features of low material cost, high chemical stability at normal temperature, high decomposition efficiency at high temperature, less pollution, simple production process and being suitable for on-line and of-line producing transparent conductive low-radiation glass coating.

Description

1. Technical field [0001] The invention belongs to the technical field of forming a transparent conductive low-emissivity glass coating on the surface of float glass, and in particular relates to a precursor solution of using tin chloride to synthesize tin through selective chemical reaction as a coating raw material. A production method for depositing a transparent conductive low-radiation doped tin oxide coating on the surface. 2. Background technology [0002] Low-emissivity glass coating is to coat one or more layers of specific metal, metal oxide or nitride or a combination thereof on the glass surface by physical or chemical methods, under the premise of ensuring the visible light transmittance as high as possible , a glass functional coating that prevents the transmission of mid- and far-infrared heat radiation energy, thereby achieving energy-saving and heat-insulating effects. Because of its low emissivity, it is called low-emissivity glass coating, and the glass c...

Problems solved by technology

[0007] Off-line vacuum magnetron sputtering uses expensive solid targets and large-scale vacuum sputtering equipment, while on-line CVD uses gaseous metal-organic compounds, which are not only expensive, but also require undecomposed raw materials and The by-products after its decomposition are processed, and the processing cost is very high

The traditional tin tetrachloride solution spraying method instantaneously decomposes and reacts at high temperature, which is difficult to control, and it is difficult to effectively deal with the large amount of hydrogen chloride gas produced continuously
