Problems solved by technology

[0004] Chinese patent 94190152.1 discloses a self-responsive laminate. An isotropic aqueous solution is sealed in at least a part of a transparent chamber. The aqueous solution can be directly seen through the transparent part. It is characterized in that, in each of the above In the isotropic aqueous solution, due to the increase of temperature, the polysaccharide derivatives dissolved in the water will gather and appear opaque scattering, thereby reducing the optical transmittance
So far, there is no report about the temperature-controlled sunshade glass with fast discoloration and long service life and its preparation method

Abstract

The invention discloses a temperature change light-control material, which is composed of a thermo-sensitive substance, a light curable monomer, a photoinitiator, crosslinked water-absorbent resin, a polyhydroxy solvent, assistants and water. The temperature controlled sunshading photochromic glass containing the temperature change light-control material is prepared by conducting laminating, dispensing, filling, rolling, curing and edge sealing on the temperature change light-control material. The temperature controlled sunshading photochromic glass prepared by the method provided by the invention is an intelligent glass capable of adjusting the transmittance of ultraviolet, visible light and infrared ray by the environment temperature and solar radiation intensity dual conditions, has the characteristics of fast discoloration speed and long service life, can achieve the effects of warm in winter and cool in summer, and significantly improves the comfort degree of living space and office area.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a temperature-variable light-adjusting material, a temperature-controlled sunshade color-changing glass containing the temperature-variable light-adjusting material and a preparation method thereof. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for improving the indoor thermal environment and improving the comfort of buildings. The means to achieve this goal is mainly to use air conditioners. In regions with hot summer and cold winter, due to hot summer and cold winter, it has become a common practice for people to use air conditioners to improve indoor thermal environment, which will inevitably increase building energy consumption and aggravate my country's energy crisis. Western developed countries have carried out research on energy-saving windows since the 1960s, such as heat-reflecting glass and Low-E glass. ...
