Preparing method for intelligent electrochromic glass

Abstract

The invention discloses a preparing method for intelligent electrochromic glass. The preparing method includes the following steps that S1, a glass substrate enters a first liquid-phase roller-coating film coating machine through a sheet feeding table, a stannic-oxide fluorine-doped transparent conducting film is coated, and then the product enters a leveling section and is subjected to leveling and surface drying; S2, the glass substrate after treatment in the step S1 is fed into a second liquid-phase roller-coating film coating machine through a transmission roller way, and the stannic-oxide fluorine-doped transparent conducting film is coated with a tungsten oxide film; S3, the glass substrate after treatment in the step S3 is subjected to heat treatment, the temperature of heat treatment is 350 DEG C to 700 DEG C, the time of heat treatment is carried out for 2 min or above, and the intelligent electrochromic glass is obtained; a stannic-oxide fluorine-doped transparent conducting film middle layer is precipitated between the glass substrate and the tungsten oxide film, an electrochromic conductive electrode is provided, and electronic transmission and ion transmission are convenient; the technology is simple, the device cost and the raw material cost are low, and the intelligent glass prepared with the method has the advantages of being sensitive in responding, large in optical modulation amplitude and the like, can be completely applied to the field of energy saving of intelligent windows, vehicles and the like, and is suitable for industrial mass production.

Description

technical field [0001] The invention relates to a preparation method of electrochromic smart glass. Background technique [0002] The existing curtain wall glass and low-e glass have heat insulation effect, and low-e glass also overcomes the shortcoming of light pollution caused by high reflection of visible light by curtain wall glass, but low-e glass cannot realize intelligent adjustment of indoor temperature . [0003] Recently, a kind of smart glass coated with electrochromic tungsten oxide film material appeared on the glass. The smart glass can adjust the energy entering the room according to the needs, and can automatically adjust the transmittance of sunlight according to the indoor temperature. In winter, when the indoor temperature is low, infrared light enters the room to increase the indoor temperature; in summer, when the indoor temperature is high, the smart window glass automatically reduces the transmittance of infrared light, preventing the indoor temperatu...
