Abstract
The preparation method of the reversible amorphous pigment of blueness pink disclosed by the invention, step include：By Co (NO3)2·6H2O and urea are dissolved in deionized water；By acquired solution drying and dehydrating, 10~180 min are heated at 240~400 DEG C, obtain the blue reversible amorphous pigment of pink.Preparation process of the present invention is simple, at low cost, and pigment obtained has unique non crystalline structure and porous pattern, which meets water and become pink, can recover blueness again after drying, can be used as intelligent pigment.
Description
Technical field
The present invention relates to the preparations of a kind of preparation method of amorphous pigment, especially blueness-reversible amorphous pigment of pink
Method can be used as intelligent pigment.
Background technology
Pigment is widely used in the industry, and color changeable pigment can be used for the fields such as intelligent pigment.Therefore, develop new
Color reversible change pigment has great importance.
The content of the invention
The object of the present invention is to provide a kind of preparation methods of blueness-reversible amorphous pigment of pink, which meets water can
Become pink, blueness can be recovered again after drying.
The preparation method of the reversible amorphous pigment of blueness-pink of the present invention, its step are as follows：
1）By Co (NO3)2·6H2O and urea are dissolved in deionized water, and the ratio between amount of substance of urea and cobalt nitrate is
8.5~17.1；
2）By step 1) acquired solution drying and dehydrating, 10~180 min are heated at 240~400 DEG C, are obtained blue-pink
The reversible amorphous pigment of color.
Preparation process of the present invention is simple, at low cost, and pigment obtained has unique non crystalline structure and porous pattern, the face
Material meets water and becomes pink, can recover blueness again after drying.It is expected to be used for the fields such as intelligent pigment.

Specific embodiment
The present invention is further explained with reference to embodiments, but the present invention is not limited solely to following embodiments.
Embodiment 1
By the Co (NO of 1.22 g3)2·6H2The urea of O and 4.2 g are dissolved in 10 mL deionized waters, are obtained transparent
Solution；Above-mentioned solution is dehydrated in 80 DEG C of dry 12 h, then directly heating 10 min at 400 DEG C obtains blue pigment.
Fig. 1 is to obtain the optical photograph of product, it can be seen that the color of the product is blueness.Product is made for this example in Fig. 2
Scanning transmission electron microscope photo, it can be seen that it is with foam-like porous structures.Fig. 3 by acquisition product constituency
Electron diffraction pattern, it is non crystalline structure to illustrate the blue pigment.Fig. 4 is the light after blue pigment prepared by this example impregnates in water
Learn photo, it can be seen that the blue pigment becomes pink after meeting water；After 150 DEG C dry, the pigment is extensive by pink
Original blueness is arrived again（As shown in Figure 5）.It is understood through mercury injection method test, the apparent density of the blue pigment（apparent
density）For 1.4 g/cm3, volume density（bulk density）For 0.3 g/cm3.The above result shows that blueness obtained
Pigment has non crystalline structure, and chance water can be changed into pink, can recover original blueness after drying.
Embodiment 2
By the Co (NO of 1.22 g3)2·6H2The urea of O and 2.1 g are dissolved in 10 mL deionized waters, are obtained transparent
Solution；Above-mentioned solution is dried overnight at 80 DEG C, then directly heating 60 min at 300 DEG C obtains blue pigment.Fig. 6 for
To the optical photograph of product, color is blueness.The blue pigment, which meets water, can be changed into pink, can recover original after drying
Blueness.
Embodiment 3
By the Co (NO of 1.22 g3)2·6H2The urea of O and 2.1 g are dissolved in 10 mL deionized waters, are obtained transparent
Solution；Above-mentioned solution is dried overnight at 80 DEG C, then directly heating 180 min at 240 DEG C obtains blue pigment.Fig. 7 is
The optical photograph of product is obtained, color is blueness.The blue pigment, which meets water, can be changed into pink, can recover original after drying
Blueness.
