Problems solved by technology

[0003] Although the above two dimmable glass structures can achieve variable dimming of the glass, for the polymer dispersed liquid crystal dimming glass, it requires an external power supply, which consumes a lot of energy, and the glass is opaque when the power is off. Difficult to meet the use requirements on building doors and windows
As for the electrochromic tinting glass, it also needs an external power supply, and there is also the problem that the light cannot be adjusted when the power is off, and this kind of glass also has the problems of unstable electrochemical characteristics and low repeatability.

Abstract

The invention provides a temperature-sensitive color-changeable material, a preparation method thereof and one-way perspective temperature-sensitive type glass. The temperature-sensitive color-changeable material comprises the following raw materials in percentages by weight: 0.5-20 parts of temperature-sensitive macromolecules, 1-20 parts of a film-forming monomer, 0-20 parts of a thickening agent, 0-0.5 part of a dispersing agent and 0.02-0.5 part of a cross-linking agent. The temperature-sensitive color-changeable material can be transparent or non-transparent by only needing to sense the temperature of an external environment, so that the color can be changed without externally energy; and therefore, the temperature-sensitive color-changeable material can be applied to a light-adjusting glass to avoid the shortcomings of an existing light-adjusting glass structure.

Description

technical field [0001] The invention relates to the technical field of glass product production, in particular to a temperature-sensitive color-changing material. The invention also relates to a preparation method of the temperature-sensitive color-changing material, and a one-way perspective temperature-sensitive glass applied with the temperature-sensitive color-changing material. Background technique [0002] In the prior art, glasses capable of intelligent dimming mainly include polymer-dispersed liquid crystal dimming glass and electrochromic dimming glass. The principle of polymer-dispersed liquid crystal dimming glass is to control the arrangement state of liquid crystal molecules through current. When there is no current passing through, the liquid crystal molecules in the electroluminescent liquid crystal atomized glass will show an irregular dispersion state, making it impossible for light to enter. for an opaque appearance. When the current is applied, the liqui...
