The invention discloses a method for producing electric heating high-insulation hot dipping glass, and relates to technological methods for processing conductive layers on insulation substrates. According to the method for producing the electric heating high-insulation hot dipping glass, the conductive glass obtained through the method is fast in temperature rising, good in heat insulation performance, capable of achieving chemical tempering, high in strength and capable of being in a curved shape. The producing method comprises the following steps that A, spraying liquid is prepared, the spraying liquid comprises, by weight, 30%-40% of butyltin trichloride, 10%-20% of trifluoroacetic acid, 0.8%-1.6% of antimonous trichloride, 40%-50% of acetone and 0.5%-1% of zinc carbonate, the acetone is used for dissolving the antimonous trichloride, and an acetone solution, the butyltin trichloride and the trifluoroacetic acid are mixed and then are added with zinc carbonate to be evenly stirred; B, the surface of the glass is cleaned, then the glass is placed in a closed space, the glass is heated to be at the temperature of 650-750 DEG C, the prepared spraying liquid is atomized and sprayed on one face of the glass, hot dipping is conducted for one to five seconds so that a stannic oxide conductive heat insulation layer can be formed, and the stannic oxide conductive heat insulation layer is naturally cooled to be at the normal temperature.

Description

technical field [0001] The invention relates to a process method for processing a conductive layer on an insulating substrate, in particular to a process method for processing an electric heating and high heat insulation layer on a glass surface. Background technique [0002] As a conventional product, glass has a wide range of uses, and has been widely used in industries such as industry, agriculture, mechanical equipment, construction, vehicles, and instrumentation. The existing transparent glass is mainly made of silicon dioxide, which has good light transmission performance, but poor thermal insulation performance, and glass as an insulator cannot conduct heat and conduct heat, which limits the further expansion of the scope of use of glass. With the rapid development of science and technology and economy, the consumption of energy is increasing day by day, and the problem of energy crisis has become increasingly prominent. As a national strategic issue, energy conservat...

Problems solved by technology

The methods commonly used at present to prepare tin dioxide conductive glass are: magnetron sputtering method, chemical vapor deposition method, sol-gel method, powder spraying method and spray pyrolysis method, but the conductive glass produced by these existing processes all exists The following problems: 1. The tin dioxide conductive film has poor adhesion, and it is easy to be scratched or collided during use, and loses its conductive function; 2. It cannot be chemically tempered at high temperature. Conductive function, so the strength of the existing tin dioxide conductive glass is not high, and it cannot be applied to fields with high strength requirements; 3. When the glass is bent, the conductive layer is easily broken by extrusion or stretching, and loses the conductive function. Some tin dioxide conductive glass cannot change its shape; 4. The existing conductive glass has poor thermal insulation performance. The tin dioxide conductive layer heats up on one side of the glass, and the heat is quickly transferred to the other side of the glass. When used in places with large temperature differences between inside and outside The heat is lost quickly, and the use effect is not ideal
