Problems solved by technology

[0005] There have been many applications of cholesteric liquid crystals in the field of temperature measurement, but it is difficult to meet the requirements of water resistance and boiling resistance, and it is difficult to realize the wide application in the measurement of drinking temperature. Therefore, there is a strong need for a strong and durable liquid crystal coating that can indicate the drinking temperature

Abstract

The invention relates to a thermochromic liquid crystal microcapsule ink, which comprises the following components by mass fraction: first water-based resin, a liquid crystal microcapsule, a first adhesion promoter and a first curing agent, the liquid crystal microcapsule mainly comprises a wall material and a core material, the core material mainly comprises cholesteric liquid crystal, and the wall material is polyurethane resin; and the invention also relates to a thermochromic coating prepared from the thermochromic liquid crystal microcapsule ink. The thermochromic coating prepared from the reversible thermochromic liquid crystal microcapsule ink can be attached to different drinking containers, has excellent boiling resistance, scratch resistance and chemical resistance, can prevent drinkers from being scalded by hot water, provides the drinkers with the temperature suitable for drinkers to drink, and enhances the decorative effect of the drinking containers at the same time.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a thermochromic liquid crystal microcapsule ink and a thermochromic coating. Background technique [0002] The temperature in the process of drinking water / tea not only affects the taste, but when the temperature is too high, it will have a strong stimulating effect on the throat, esophageal mucosa and stomach, easily damage local cells, and increase the risk of esophageal cancer; according to "Iran A study on the relationship between esophageal cancer and esophageal cancer in northern areas with high incidence of esophageal cancer shows that there is a strong correlation between the habit of drinking beverages that are too hot (65°C and above) and the higher incidence of local esophageal cancer; according to the recent "Tea Drinking Research progress on the relationship between esophageal cancer and esophageal cancer shows that eating high-temperature food will increase the risk of...
