[0037] In another aspect, the present invention provides a method for preparing the above-mentioned inorganic pigment, comprising the following steps: mixing raw materials, calcining at a temperature of 850-1250° C., and obtaining the inorganic pigment after cooling.

[0038] Calcination is an important process for material preparation. The calcination process directly affects the microstructure such as grain size and distribution, pore size and distribution, and grain boundary volume fraction in the calcined compact. Calcination is a general term for the densification process and phenomenon of materials at high temperatures. As the temperature rises and the time prolongs, the solid particles are bonded to each other, the grains grow, and the voids (pores) and grain boundaries gradually decrease. During the calcination process, through the transfer of substances, its total volume shrinks, its density increases, and finally it becomes a hard polycrystalline sintered body.

Abstract

The invention relates to the field of pigment processing, and particularly provides inorganic pigment and a preparation method and application thereof. The inorganic pigment is mainly prepared from titanium dioxide, calcium oxide and kaolin. According to the inorganic pigment, the kaolin is used for replacing traditional harmful materials such as lead chromate and cadmium sulfide, the applicationrange of the pigment is expanded, and pollution cannot be caused to a human body and the environment. Meanwhile, the inorganic pigment is completely prepared from inorganic materials, the properties of light resistance, tinting strength, hiding power, water resistance and the like are very good, the ingredients are uniform, the performance is stable, resources of raw materials are wide, and therefore the cost is low. The preparation method of the inorganic pigment comprises the steps that mixed raw materials are calcined under the condition of 850-1,250 DEG C, cooling is conducted, and the inorganic pigment is obtained. According to the method, operation is easy, no special requirements are needed for equipment, the cost is low, and the method can be used for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of pigment processing, in particular to an inorganic pigment and its preparation method and application. Background technique [0002] In the production of floor tiles, square tiles and colored ceramic aggregates in the construction industry, pigments are needed to color the body, among which, the largest amount of pigments is used in the production of square tiles. [0003] Pigments are divided into organic pigments and inorganic pigments. Inorganic pigments are oxides of non-ferrous metals, or some metal insoluble metal salts, and can be divided into two types: achromatic pigments and colored pigments. Among them, achromatic pigments include a series of pigments from white, gray to black, and they only show differences in the amount of reflected light, that is, differences in brightness. Color pigments can selectively absorb light of a certain wavelength, and reflect light of other wavelengths to present various c...
