Abstract

The invention relates to the technical field of glassmaking, in particular to double-layer photochromic glass. The double-layer photochromic glass comprises a glass bottom plate and a glass cover plate and is characterized in that a sandwich cavity is arranged between the glass bottom plate and the glass cover plate, a photochromic sandwich layer is arranged in the sandwich cavity, the material used by the photochromic sandwich layer comprises the mixture of one or more of benzopyran, fulgide, photochromic spirooxazine, and diarylethene or metal dithizone salt. A production method of the glassincludes the steps of firstly, preprocessing the glass; secondly, etching the sandwich cavity; thirdly, preparing the photochromic sandwich layer; fourthly, preprocessing the glass bottom plate; fifthly, performing glass laminating. The glass has the advantages that the glass can have different colors in different light states, the color changing process does not need to be controlled by electricenergy or heat, energy conservation and reliability are achieved, and the glass is quite suitable for being used as building door and window glass, high in functionality and good in decoration performance.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a double-layer color-changing glass. Background technique [0002] Color-changing glass is a new type of glass, which can undergo controllable changes in optical properties according to changes in the external environment. The changes in these optical properties include changes in reflectivity, transmittance and absorptivity. The intuitive performance is the change of the glass. Color and transparency changed. This kind of glass has broad application prospects in the fields of information, electronics, agriculture, construction, agriculture, and national defense. For example, the use of this glass in greenhouses can realize automatic control of light, and the use of this glass in buildings can adjust indoor light without installing curtains. [0003] At present, electrochromic glass is mainly used in conventional color-changing glass. Patent announcement CN201510262...
