The preparation method of above-mentioned reversible thermochromic composite is as follows:
Weigh dyestuff, organic amine, solid fatty alcohol according to the ratio described in claim 1 and mix, then
Heating and melting alcoholic solvent also cools down after being sufficiently stirred for, i.e. available required reversible thermochromic composite, its
Discoloring temperature is 40-65 DEG C, when temperature arrive particular value or specific interval time, its material system by purple to
Yellow changes, and when temperature reduction recovers to particular value, its color generation Back Up.
The present invention compared with prior art, has the advantage that and beneficial effect:
1, the reversible thermochromic material of the present invention is prepared fairly simple, and environmental protection is reliable and stable, and color becomes
Changing distinctness, material is easy to get, and implements easily.
2, the reversible thermochromic of material of the present invention is highly sensitive, and reversible color is lasting, discoloring temperature interval master
40-65 DEG C to be concentrated on；When temperature arrives certain particular value or the narrowest specific interval, its material
System is changed to yellow by purple；When temperature reduction recovers to particular value, there is reverse change in its color
Change.
Accompanying drawing explanation
Fig. 1 is the thermo-color complex chromatic aberration figure with temperature of gained in embodiment 1.
Fig. 2 is the thermo-color complex chromatic aberration figure with temperature of gained in embodiment 4.
Detailed description of the invention
Below in conjunction with multiple specific embodiments, the invention will be further described.
Embodiment 1
Raw material is as follows:
Dyestuff (specially alizarin red agent), for colour former；Organic amine (specially tripolycyanamide), for developer；
Solid fatty alcohol (specially hexadecanol), for solvent.Wherein, alizarin red agent: tripolycyanamide: the matter of hexadecanol
Amount ratio is 1:50:200.
Preparation method is as follows:
Weighing the hexadecanol mixing of the alizarin red agent of 0.1g, 5g tripolycyanamide and 20g, then heating and melting alcohol is molten
Agent cools down after being sufficiently stirred for 5min, i.e. obtains purple wax after cooling, when heating this wax to 50 DEG C,
Solid color from purple becomes yellow, continues heating, becomes yellow liquid, cool down the most at normal temperatures and pressures,
Color has yellow liquid to become yellow solid to become violet solid again, and chromatic aberration is as shown in Figure 1.
