Abstract

The utility model provides a dynamic texture ceramic which comprises a ceramic body, a thermochromic pigment layer coated on the surface of the ceramic body, a transparent protective layer coated on the outer side of the thermochromic pigment layer and used for ensuring long-term stability and use effect of the thermochromic pigment layer, and a pipeline part arranged on the inner wall of the ceramic body and used for circulating a thermal fluid so as to transfer heat to the thermochromic pigment layer, so that the thermochromic pigment layer changes color, and the pipeline part is printed by a ceramic 3D printing technology. By allowing the hot fluid to flow in the pipe portion, the ceramic body surface is capable of reversible color change, creating a dynamic pattern that is more abundant and computable than conventional thermochromic cups.

Description

Dynamic texture ceramic Technical Field The utility model relates to the technical field of dynamic texture ceramics, in particular to a dynamic texture ceramic. Background Ceramic is rarely explored as a common decorative and daily material as an object capable of exhibiting an animation effect. At present, research on ceramic 3D printing in the field of human-computer interaction is mainly focused on the following aspects: Optimizing the printing quality, namely optimizing a printing path through special software so as to realize accurate printing of complex geometric structures. Exploring innovative printing materials researchers are working to improve material properties to expand the design possibilities of ceramic 3D printing. For example, clay is mixed with a dough of biomaterial, or fiber filaments are embedded in the extruded clay to enhance tensile strength, thereby achieving printing of complex overhanging and unsupported structures. The related research explores various methods for controlling the printing process, such as printing based on a hand-drawn path, controlling by using a joystick, or interacting by means of a visual panel, so that the user can participate in the printing process more directly. However, at present, for realizing the animation surface effect on the ceramic material, the dynamic effect and the information display are not abundant enough, and are usually thermochromic cups which can only realize the color change from bottom to top.

The flow channel layer is a material with a fluid channel embedded in the surface of the object, the fluid layer is fluid with different temperatures used as a heat source and a cold source, the heat conduction layer is an optional layer which is not required to be present and is used for enhancing the temperature diffusion of the surface of the flow channel layer, and the drawing layer can make a color change response according to the temperature change by using thermochromic pigment. Thus, in operation, the composite color change material flows through the flow channels embedded under the object surface at different temperatures, and the temperature of the object surface is dynamically changed and controlled due to heat conduction, which activates the color change effect of the thermochromic pigment of the drawing layer, thereby generating a texture movement effect.
