Embodiment 1

[0036] Implementation example 1, materials include: 200 grams of acetone solvent, 50 grams of 40-degree color-changing yellow pigment, and 50 grams of environmentally friendly thickener dibutyl sebacate. Add the above raw materials into a beaker and stir in a fume hood for 10 minutes to form a uniform viscous solution, take out part of the solution and brush it flat on a flat mold with 2 mm deep grooves, ventilate and dry to obtain the color-changing film.

[0037] As a modification of this embodiment, part of the viscous solution can be added to the mold first, then the electric heating layer net is fixed above the solution, and then the rest of the solution is brushed on the electric heating layer, so that the electric heating layer has a solution, after drying, the electric heating layer is embedded within the film.

Embodiment 2

[0038] Implementation example 2, materials include: 200 grams of water-based colorless paint, 50 grams of 40-degree color-changing blue pigment. Add the above raw materials into a beaker and stir in a fume hood for 10 minutes to form a uniform viscous solution, take out part of the solution and brush it flat on a flat mold with 2 mm deep grooves, ventilate and dry to obtain the color-changing film.

Embodiment 3

[0039] Implementation Example 3, the materials include: 200 grams of water-based colorless paint, 50 grams of 40-degree color-changing green pigment, and 5 grams of pressure-sensitive pigment. Add the above raw materials into a beaker and stir in a fume hood for 10 minutes to form a uniform viscous solution, take out part of the solution and brush it flat on a flat mold with 2 mm deep grooves, ventilate and dry to obtain the color-changing film. The film obtained in this example has dual functions of controllable discoloration and pressure-sensitive discoloration.

[0040] The modified example of implementation example 3: repeat embodiment 1, change the heat-sensitive pigment wherein into 50 grams of pressure-sensitive pigments, obtain the color-changing film containing pressure-sensitive pigment; Then the color-changing film containing heat-sensitive pigment of embodiment 1 and front The obtained color-changing films containing pressure-sensitive pigments are laminated togeth...

Abstract

The invention relates to a controllable flexible color change display material and a production method thereof. The material comprises an electric heating layer, a color change film layer and a transparent protecting layer. The color change film layer is arranged on one side or two sides of the electric heating layer, or the electric heating layer is embedded in the color change film layer, and the electric heating layer and the color change film layer are packaged in the transparent protecting layer. The low-cost active type color change display material can be provided, and the large-range color change effects such as field color change identification and large-area advertisement color change identification are achieved.

Description

technical field [0001] The present application relates to a color-changing material, especially a controllable flexible color-changing display material and a production method thereof. The controllable flexible color-changing display material can be used in different application fields, and can be used in different combinations according to needs. Background technique [0002] At present, thermochromic materials have been developed for a variety of purposes, but there are not many products that endow this material with a wider range of uses through the application of multiple technologies across disciplines. A very important reason for this is that the relevant material technology has not reached the corresponding height. In addition, most of the color-changing materials in the prior art have complex structures and high production costs. [0003] In the application number: CN200910203510.8, an electrochromic material and an electrochromic device using the electrochromic ma...
