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-e glass coating on the surface of float glass, and in particular relates to a precursor solution of using an inorganic compound of tin to synthesize tin through selective chemical reaction as a coating material. A production method for depositing a transparent conductive low-radiation doped tin oxide coating on the glass surface. 2. Background technology [0002] Low-emissivity glass coating is to apply one or more layers of specific metal, metal oxide or nitride or a combination of coatings on the glass surface by physical or chemical methods, under the premise that the visible light transmittance is as high as possible It is a kind of glass functional coating that prevents the transfer of mid- and far-infrared thermal radiation energy, so as to achieve the effect of energy saving and heat preservation. It is called low-emissivity glass coating because of its low emissi...

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
