Abstract

The invention provides a thermochromic sheet as well as a preparation process and application thereof, and relates to the technical field of laminated glass, the thermochromic sheet is prepared from the following components in parts by weight: 47-81.45 parts of resin powder, 10-25 parts of a color-changing auxiliary agent, 8-25 parts of a low-polarity plasticizer, 0.2-1.0 part of a nano dispersion liquid, 0.1-1.0 part of an antioxidant and 0.25-1.0 part of a light stabilizer, the components are blended and extruded to obtain the thermochromic sheet, and the thermochromic sheet is prepared from the thermochromic sheet. The method can be applied to manufacturing laminated glass. The thermochromic sheet provided by the invention is transparent in the color changing process, can improve the visible light transmittance of thermochromic glass, and has a good visual effect.

Description

technical field [0001] The invention provides a thermochromic sheet, a preparation process and application thereof, and relates to the technical field of thermochromic glass. Background technique [0002] Color-changing glass can change color under certain conditions such as light, temperature, electricity, etc., and change accordingly with the change of conditions. After the external pressure conditions disappear, it can return to its original state. In the construction industry, color-changing glass is widely used. Commonly used color-changing glass includes liquid crystal dimming glass, all-solid electrochromic glass and photochromic glass. The liquid crystal dimming glass needs to use the control circuit to realize the switching between the two states of transparency and atomization. This kind of glass only has two states: transparent and atomized, suitable for indoor use as partition, not suitable for curtain wall and outdoor doors and windows. Moreover, the control ...
