Embodiment Construction

[0024] After mixing diatomite and zircon with a mass ratio of 1:1, put them into a pulverizer to pulverize for 1 to 2 hours, pass through a 150-mesh sieve after pulverization, collect the pulverized inorganic minerals, and set aside; take corn stalks, put them in Pulverize in a pulverizer for 1 to 2 hours, pass through a 150-mesh sieve after pulverization, and collect the sieved powder. Add the sieved powder and 5% sodium hydroxide solution into the mixer according to the mass ratio of 1:2. Under the condition of 80-100°C, stir and react for 1-2 hours to obtain a mixed solution, then add a hydrochloric acid solution with a mass fraction of 4% to the mixed solution until the pH becomes 2-3, filter, collect the filtered powder, and obtain a lignin-containing powder; mix the standby inorganic mineral pulverized material with the above-mentioned lignin-containing powder at a mass ratio of 2:1, pour it into the reaction kettle, and stir the reaction for 30-40 minutes at a temperatur...

Abstract

The invention discloses a preparation method of a dense and stable type ceramic pigment and belongs to the technical field of ceramic pigments. The preparation method firstly takes diatomite and zircon as raw materials and the raw materials are crushed and sieved to obtain sieved powder; the diatomite has a porous structure, stable chemical properties, low density and relatively large specific surface area, and can be used for filling gaps generated by solvent evaporation in the ceramic pigment, so that the microstructure of the ceramic pigment is more dense; lignin is extracted from corn straws; after the lignin is added, the strength of the ceramic pigment can be increased and the cracking of the ceramic pigment is prevented; the reserved sieved powder and the lignin are mixed so that the lignin can be adsorbed in gap structures of inorganic minerals; a hydrogen bond adsorption force can be generated between active groups and an active group of the surface of a ceramic substrate; the inorganic minerals stuck with the lignin and copper ammonia fibers are mixed and then are calcined and ground to prepare the dense and stable type ceramic pigment. The dense and stable type ceramicpigment has a wide application prospect.

Description

technical field [0001] The invention discloses a preparation method of a compact and stable ceramic color material, which belongs to the technical field of ceramic color material. Background technique [0002] With the rapid development of the ceramic industry and decoration technology and the improvement of people's aesthetic taste, the requirements for the beautification of ceramic appearance are getting higher and higher. Ceramic glaze pigments, as one of the main decorative materials, play an important role in the appearance of ceramics. Ceramic sleeve products have a history of hundreds of years since their production and development. However, as far as the current domestic production situation is concerned, it is still difficult to prepare products with pure color, bright glaze and minimal color difference. [0003] Whether it is to prepare pure black ceramic pigments or bright red ceramic pigments, it is necessary to strictly control the process indicators of each pr...
