Abstract

The invention discloses a medical low-temperature reversible temperature-indicating coating and a preparation method thereof; raw materials comprise epoxy modified organic silicon resin, lead dioxide, ethyl cellulose, cadmium carbonate, calcium fluoride, a talcum powder, barium sulfate, Sudan orange, titanium dioxide and red cyanine; the product is in reversible single color change at the temperature of 70-90 DEG C, a color is turned from red to purple, and the color is turned from purple to orange at the temperature of 140-180 DEG C; the product has the viscosity of 60-80 s, is resistant to water for 3-7 d without blistering, is non-toxic and has good heat resistance, and the temperature measurement range is from room temperature to 200 DEG C; and temperature measurement is fast, simple and reliable, and the product can be widely produced and constantly replaces conventional materials.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a medical low-temperature reversible temperature-indicating coating and a preparation method thereof. Background technique [0002] Temperature-indicating paint, when the coating is heated to a certain temperature, the color or other phenomena change to indicate the surface temperature and temperature distribution of the object is called temperature-indicating paint, usually also called color-changing paint or heat-sensitive paint. Screen printing ink Screen printing type anti-counterfeiting ink can be used under 350 mesh, the pattern effect is good, smooth, and the color is full, and all the above-mentioned anti-counterfeiting materials can meet the requirements of silk screen printing. [0003] According to the stability of the color after the temperature-indicating coating changes color, it can be divided into reversible temperature-indicating coatings and irreversi...
