preparation example Construction

[0050] The preparation method of the above-mentioned thermochromic container comprises the following steps:

[0051] 1) Clean the container body, and then dry to remove surface moisture;

[0052] 2) Add water-based resin, thermochromic toner, ordinary toner, dispersant, defoamer and adhesion promoter into a three-stage ball mill, fully grind evenly, and then add water to obtain a thermochromic paint;

[0053] 3) spraying the temperature-sensitive color-changing paint on the surface of the container body, drying, and baking to obtain a temperature-sensitive color-changing layer;

[0054] 4) Spray a layer of transparent protective layer on the temperature-sensitive color-changing layer or first heat transfer the pattern layer and then spray a layer of transparent protective layer, or set the pattern in the temperature-sensitive color-changing layer by thermal sublimation process and then spray a layer of transparent protection layer to obtain a thermochromic container.

Embodiment 1

[0059] 1) Clean the white ceramic cup and dry it at 80°C for 30 minutes to remove the surface moisture;

[0060] 2) Add water-based acrylic resin, 43-degree black discoloration powder, ordinary red toner (no discoloration), anionic surfactant, modified polysiloxane and epoxy silane into the three-stage ball mill, fully grind evenly, and then Add water and mix evenly to obtain thermochromic paint;

[0061] 3) Spray the temperature-sensitive color-changing paint on the outer surface of the white ceramic cup, dry it, and bake it at 150°C for 50 minutes to obtain a temperature-sensitive color-changing layer;

[0062] 4) Spray a transparent protective layer on the temperature-sensitive color-changing layer to obtain a temperature-sensitive color-changing cup.

[0063] The temperature-sensitive color-changing cup prepared in this example is brown in appearance at room temperature, and will gradually change color after adding hot water above 50°C, and finally turn red, and the cup w...

Embodiment 2

[0065] 1) Clean the transparent glass and dry it at 100°C for 15 minutes to remove the surface moisture;

[0066] 2) Add water-based epoxy resin, 45-degree dark blue discoloration powder, ordinary pink toner (no discoloration), anionic surfactant, modified polyol and vinyl silane into a three-stage ball mill, fully grind evenly, then add water and mix Evenly, a thermochromic paint is obtained;

[0067] 3) Spray the temperature-sensitive color-changing paint on the outer surface of the transparent glass, dry it, and bake it at 170°C for 40 minutes to obtain a temperature-sensitive color-changing layer;

[0068] 4) Water-transfer the white flower paper on the temperature-sensitive color-changing layer, and then spray a layer of transparent protective layer to obtain the temperature-sensitive color-changing cup.

[0069] The temperature-sensitive color-changing cup prepared in this example is purple in appearance at room temperature, and a white floral paper pattern can be seen....

Abstract

The invention discloses a thermochromic coating and a thermochromic container. The thermochromic coating is prepared from the following raw materials in parts by mass: 100 parts of water-based resin, 10 to 50 parts of a thermochromic toner, 10 to 50 parts of a common toner, 0.5 to 0.9 part of a dispersing agent, 0.5 to 1 part of a defoaming agent, 1.5 to 2.5 parts of an adhesion promoter and 20 to 50 parts of water. The thermochromic container comprises a container body, a thermochromic layer arranged on the surface of the container body, and a transparent protective layer arranged on the thermochromic layer; the thermochromic layer is obtained by drying and curing the thermochromic coating; the transparent protective layer is obtained by drying and curing a transparent coating. The thermochromic coating and the thermochromic container are rich in color change; diversified patterns are arranged on the container; a preparation process is simple; the thermochromic layer and the container body are closely combined and difficult to fall off; furthermore, the transparent protective layer is arranged on the outermost layer of the container, so that the durability of the color and the pattern on the surface of the container can be guaranteed.

Description

technical field [0001] The invention relates to a temperature-sensitive color-changing paint and a temperature-sensitive color-changing container. Background technique [0002] Thermochromic paint is a paint that changes color as temperature changes. The reason for the color change is that thermochromic paint is added with thermochromic toner. Temperature-sensitive color-changing paint is often used to prepare color-changing cups, also known as magic cups, which can usually be divided into cold color-changing cups and thermal color-changing cups. Generally, cold color-changing cups use color-changing materials that change at 7-17°C, and they will change color when the temperature is lower than this temperature; while thermal color-changing cups generally use color-changing materials that change at about 40°C, and they will change color when the temperature is higher than this temperature. The current color-changing cups have a single color change, and usually only one color...
