Description
Technical Field
The application relates to the technical field of functional coatings, in particular to a weather-resistant electrochromic coating and a preparation method thereof.
Background
The electrochromic paint is a novel functional paint, has good indication function and beautifying effect, has excellent optical characteristics, and has wide application in the aspects of high-grade hotels, museums, conference offices, banks, commercial showcases, automobile windows and the like. The material can realize stable and reversible color conversion of reflectivity and transmissivity under the action of an external electric field, and can realize the interconversion between a colorless transparent state and an atomized opaque state.
The existing electrochromic paint has the defects of poor weather resistance, short service life, poor electrochromic effect and reversibility, insufficient adhesion force with a base material, unstable property and easy oxidative decomposition after long-term exposure to air, thereby causing the paint to lose the color-changing property. In order to solve the above problems, chinese patent application CN114163902a discloses an electrochromic layer coating, an electrochromic device and a method for preparing the same. The electrochromic layer coating comprises the following components in parts by weight: 1-60 parts of resin; 0.01-50 parts of functional monomer; 0.01-50 parts of cross-linking agent; 0.001-1.5 parts of conductive material; 0.001-5 parts of initiator; 0.001-0.01 part of UV absorber; 0.01-50 parts of liquid crystal glue. According to the application, the conductive layer is directly compounded into the electrochromic layer for the first time, so that the problem of increase of the b-value of the electrochromic device caused by superposition of the conductive film layer is avoided, the prepared electrochromic device basically does not yellow, has the characteristic of illumination resistance, and has the advantages of high color changing speed, stable performance, long service life, simplicity in preparation, low cost and good application value. However, the paint has insufficient weather resistance, short service life and poor storage and transportation stability.
Therefore, the weather-resistant electrochromic paint with good performance stability, sufficient weather resistance and remarkable electrochromic effect and a preparation method thereof are still needed in the field.
