Problems solved by technology

Among them, the unit cost of photochromic materials is expensive, and the color change is single; thermochromic materials require high heat to drive; electrochromic materials have a wide color gamut and flexible control, but the color saturation is insufficient in the background of natural light; solvent-induced coloring The toning range is large and the color saturation is high, but it is difficult to achieve reversible adjustment

Embodiment 1

[0035] Such as figure 1 and figure 2 As shown, the composite color-changing material system of this embodiment includes a composite film layer 2 and a "rainbow" film layer 5 located at the bottom of the composite film layer 2 for improving the color mottled effect. The composite film layer 2 is composed of three different colors. The film layers 1 are stacked, and each color film layer 1 is printed with color dots 3 of different sizes (the colors in each color film layer 1 are red, brown, and yellow), and the "rainbow" film layer 5 is printed There are continuously distributed "rainbow" colors, each color film layer 1 and "rainbow" film layer 5 in the composite film layer 2 are movable, and different color film layers 1 and "rainbow" film layers 5 can pass through each film The movement of the layers realizes the mutual superposition of any parts.

[0036] In this embodiment, the color dots 3 on each color film layer 1 have the same color, and the area size of the color dot...

Embodiment 2

[0047] The composite color-changing material system in this embodiment and the color adjustment method of the composite color-changing material system are basically the same as those in Example 1 (the color of each color film layer 1 can be adjusted according to actual needs).

[0048] The composite color-changing material system in this embodiment is used in the field of building exterior walls to obtain color-changing building exterior walls. The side view of the color-changing building exterior walls is as follows Figure 5 As shown, the color-changing building exterior wall includes an exterior wall body 101, and the exterior surface of the exterior wall body 101 is sequentially provided with a composite film layer 2, a "rainbow" film layer 5 and a black and white film layer 6 from the outside to the inside. The end is equipped with a film layer position adjustment mechanism (that is, a roller adjustment system).

[0049] In this embodiment, the color of the outer wall of ...

Embodiment 3

[0052] The composite color-changing material system in this embodiment and the color adjustment method of the composite color-changing material system are basically the same as those in Example 1 (the color of each color film layer 1 can be adjusted according to actual needs).

[0053] The composite color-changing material system in this example is used in the packaging field to obtain a large-scale color-changing packaging box. The side view of the large-scale color-changing packaging box is as follows Figure 6 As shown, the large-scale color-changing packaging box includes a packaging box body 102, and the outer surface of the packaging box body 102 is sequentially provided with a composite film layer 2, a "rainbow" film layer 5, and a black and white film layer 6, and the two ends of each film layer Equipped with a film layer position adjustment mechanism (that is, a roller adjustment system).

[0054] In this embodiment, one or more sides of the packaging box body 102 can...

Abstract

The invention discloses a composite color changing material system with multi-film layer overlapping color forming. The system comprises a composite film layer and a rainbow film layer located at thebottom of the composite film layer and used for improving the color mottle effect. The composite film layer is formed by stacking a plurality of color film layers of different colors. Color dots of different area sizes are printed on each color film layer. The rainbow film layer is printed with a continuously distributed rainbow colors. Each color film layer in the composite film layer and the rainbow film layer are movable. Different color film layers and the rainbow film layer can realize mutual superposition of any parts through the movement of each film layer. The invention also correspondingly provides the color adjusting method and the application of the composite color changing material system. The composite color changing material system has the advantages of being low in cost, rapid in adjustment, good in repeatability, high in environmental matching degree, and the like.

Description

technical field [0001] The invention belongs to the field of color-changing materials, and in particular relates to a composite color-changing material system which can adjust colors arbitrarily, and a color adjustment method and application thereof. Background technique [0002] Color-changing materials are widely used in digital, automobile, construction, clothing and spinning and other fields. There are four main types of functional chromic materials according to the way they are stimulated: photochromic materials, electrochromic materials, thermochromic materials and solvent chromic materials. The most typical application of photochromic materials is color-changing sunglasses: the silver halide particles in the glass interlayer decompose when illuminated, and the colloidal silver particles and halogen elements block the light and appear black; when the light stimulus is released, the silver particles and halogen elements recombine to form Colorless silver halide, transp...
