Embodiment 1

[0022] The preparation method of red photonic crystal structure color glaze comprises the following steps:

[0023] 1) According to volume percentage, take 80% absolute ethanol, 10% ammonia water with a mass concentration of 25%, 5% deionized water and 5% tetraethyl orthosilicate, and first mix absolute ethanol, ammonia water and Put deionized water in a three-necked flask, mix well, and put it in a constant temperature water bath at 40°C. After the temperature is constant, add ethyl orthosilicate and react for 3.5 hours to obtain SiO 2 Microsphere reaction solution;

[0024] 2) SiO 2 After the microsphere reaction solution was centrifuged at 6000r / min for 15min, the precipitate was collected, washed twice with deionized water, and then washed twice with absolute ethanol, then placed in an electric blast drying oven and dried at 60°C to obtain a single Dispersed SiO 2 Microspheres;

[0025] 3) The monodisperse SiO 2 The microspheres were added to absolute ethanol, and ult...

Abstract

The invention discloses a preparation method of red photonic crystal structured colored glaze, which belongs to the technical field of ceramic glaze preparation. The preparation method comprises the following steps: 1) preparing anhydrous ethanol, ammonia water, water and ethyl orthosilicate in percentage by volume, and after the anhydrous ethanol, the ammonia water and the water are fully and uniformly mixed firstly, adding the ethyl orthosilicate into the obtained mixture, and stirring to have reaction to obtain SiO2 microsphere suspension liquid; 2) centrifuging the SiO2 microsphere suspension liquid, taking precipitates, and washing and drying the precipitates so as to obtain monodisperse SiO2 microspheres; 3) adding the monodisperse SiO2 microspheres into the anhydrous ethanol, carrying out ultrasonic dispersion so as to obtain a SiO2 microsphere emulsion; and 4) putting a ceramic substrate vertically into the SiO2 microsphere emulsion, carrying out vacuum drying until the anhydrous ethanol in the SiO2 microsphere emulsion is completely volatilized, and finally preparing a red photonic crystal structured colored glaze on the surface of the ceramic substrate. Because no pigment or coloring oxide is introduced, the method has the advantages of energy saving and environmental protection, has a broad application prospect, and can be applied to the preparation of red glaze for artistic ceramics, antique ceramics, floor and wall tiles and other ceramics.

Description

technical field [0001] The invention belongs to the technical field of ceramic glaze preparation, and in particular relates to a preparation method of a red photonic crystal structured colored glaze. Background technique [0002] Structural color is the reflection, interference or diffraction of light caused by the structural characteristics of substances, thus producing structural color, which is a new direction of color chemistry today. Structural color generation is mainly achieved through technologies such as dielectric layer stacking, etching lithography, and colloidal assembly. Among them, the colloidal assembly method is simple, easy, and relatively fast, and is currently the most widely used. It is mainly to assemble the colloidal particles in an orderly manner to form a photonic crystal with alternating high and low refractive index materials. color. [0003] Throughout the domestic ceramic glaze industry, its color is basically made of pigments. The color is unst...
