The invention relates to a temperature-sensing color-changing material which comprises a film-forming substrate, a pigment which changes color along with the change of temperature and a color-changing additive, and the weight percentage of each component is as follows: the film-forming substrate is 75-78 percent, the pigment which changes the color along with the change of the temperature is 20-23 percent and the additive is 1-23 percent. The temperature-sensing color-changing material is applied onto an outer wall of an electric kettle, and the electric kettle can display different colors according to different temperatures during the heating process. The invention provides the temperature-sensing color-changing material which is difficult to damage an outer shell and strong in practicality during the use and the electric kettle with the temperature display function.
Description
technical field [0001] The invention relates to a temperature-sensitive color-changing material and its application in an electric kettle. Background technique [0002] Microencapsulated reversible thermochromic substances are called reversible thermochromic pigments (commonly known as: temperature-changing pigments, temperature-sensitive powders or temperature-changing powders). The particles of this pigment are spherical, with an average diameter of 2-7 microns (a micron is equal to one thousandth of a millimeter). The inside is a discoloration substance, and the outside is a transparent shell with a thickness of about 0.2-0.5 microns that neither dissolves nor melts. It is it that protects the discoloration substance from other chemical substances. Therefore, it is very important to avoid damaging this layer of shell during use. [0003] Cookware products are closely related to human's daily life. If the appearance of the electric kettle made of temperature-sensitive an...
