preparation example Construction

[0028] Concrete preparation method is as follows steps:

[0029] Step ① Weigh cadmium sulfate (CdSO 4 •8H 2 O) and zirconium oxychloride (ZrOCl 2 •8H 2 O), add water to dissolve; the added quality of water is 3-5 times of the weight of the solid.

[0030] ② Weigh urea and thiourea according to the formula table, and add water to dissolve; the added quality of water is 5-10 times of the weight of solid matter.

[0031] ③ Weigh the dispersant polycarboxylate and PVP according to the formula table, and dissolve them in 2000-2500ml of water.

[0032] ④Mix the solutions in steps ①-③, add the silicon source, and mix evenly; in this step, ultrasound can be used to assist dispersion.

[0033] ⑤Pour the mixed reaction solution in step ④ into the reaction kettle, adjust the temperature to 60-200°C, the rotation speed to 100-300r / min, and react for 5-24h.

[0034] ⑥ Take out the reaction precursor obtained in step ⑤, wash with water, filter with suction, and dry.

[0035] ⑦ Mix the ...

Abstract

The invention discloses a yellow cadmium-wrapped pigment. The fineness of pigment powder is 0.5 to 3 [mu]m. The invention further provides a method of the yellow cadmium-wrapped pigment. The method comprises the following steps: putting cadmium sulfate, zirconium oxychloride, thiourea, urea, white carbon black, polycarboxylate and polyvinylpyrrolidone which serve as raw materials into water, mixing and stirring till the raw materials are dissolved, putting the solution into a reaction kettle, carrying out reaction under conditions of the temperature of 60 to 200 DEG C and rotating speed of 100 to 300 r / min for 5 to 24 hours, after the reaction is completed, carrying out natural cooling to obtain a pigment precursor, and carrying out washing, sintering and drying to obtain the yellow cadmium-wrapped pigment finished product. The mole ratio of the cadmium sulfate, the zirconium oxychloride, the thiourea, the urea, the white carbon black, the polycarboxylate and the polyvinylpyrrolidone is (6 to 15): (25 to 40): (5 to 35): (60 to 250): (10 to 50): (0.02 to 8.0): (0.01 to 4.0).

Description

technical field [0001] The invention belongs to the field of inorganic pigments and ceramic materials, and specifically relates to a yellow cadmium-based wrapped pigment and a preparation method thereof, and also relates to a ceramic ink using the pigment and a preparation method thereof. Background technique [0002] Ceramic pigments belong to the category of inorganic pigments, known for their high-temperature stability in ceramic bodies and glazes, making them different from inorganic pigments widely used in other industries, such as paints and printing pigments. In the traditional ceramic industry, the various performances of colored glazes have always been the key indicators affecting the quality of ceramic products, including color stability, chemical stability, controllability of chroma and range of variation. Research is also mainly carried out around improving the key performance indicators mentioned above. Inorganic pigments are different from organic pigments lar...
