S1, oil phase configuration：All raw materials are weighed up by formula first, then glycerine is added in pot, adds and weighs up
NS8800, Dihydroxyaluminium Aminoacetate, disodium salt, CMC press powder in pot, with blender, and glycerine is allowed to infiltrate powder, in order to avoid powder when stirring
It splashes, then pot and blender is installed, low speed stirs 1 minute, and speed of agitator 30-35r/min, middling speed stirs 8 minutes, 60-
65r/min allows glycerine to be stirred with powder；
S2, water phase configuration：K90 is added by formula in mixer, then pure water is added by formula, is stirred evenly, until
It can't see sticky matter in water, then the tartaric acid weighed up, preservative, color-change resin be poured into water and stirred evenly；
S3, vacuum stirring：Oil phase and water phase are poured into successively and are stirred under vacuum in tank, then pennyroyal freshener is put into very
In empty agitator tank, it is then evacuated down to -90mpa again, then stirs soon 2-3 minutes, speed of agitator 75-77r/min, then 6- is stirred slowly
5 minutes, speed of agitator 40-45r/min；
Step 5: coating：Hydrogel color-change resin made from step 4 is coated on bamboo charcoal drying layer 4 made from step 2
On, Reversible thermochromic hydrogel layer 2 is formed, antiadhesion barrier 3 is then gone up again, finished product is made.
Step 6: solidification：The finished product that step 5 obtains is placed on curing room to cure, until the taking-up that is cured；
Step 7: packaging：By 13 phase of the first sealing strip on the second sealing strip 31 and PU films composite layer 1 on antiadhesion barrier 3
Mutual fitted seal, then carry out pack packaging.
The application method of the present invention：After opening the package, by unlocking antiadhesion barrier 3, make the second sealing strip on antiadhesion barrier 3
31 detach with the first sealing strip 11 on PU film composite layers, and then the Reversible thermochromic hydrogel layer 2 being exposed is placed
In the place that needs are brought down a fever, the variation of color then can be clearly observed by tracing cloth, understands the situation of change of temperature.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
