Embodiment 1

[0037] Preparation of fragrance ceramic decorative plate:

[0038] (a) Weigh 300kg of kaolin, 150kg of calcined bauxite, 18kg of mineralizing agent aluminum fluoride, 18kg of sintering aid molybdenum oxide and 24kg of reinforcing agent silicon carbide (average particle size is 10 μm), put them in a ball mill jar, add water and ball milled for 12 hours to obtain a ceramic slurry with a median diameter of 7.0 μm, which was then dried by a spray tower to obtain green body powder. Wherein, the mass fraction of alumina in the chemical composition of kaolin is higher than 32%, while the mass fraction of alumina in the chemical composition of the calcined bauxite is between 55% and 80% (mass fraction), and the content of titanium oxide and iron oxide The total is less than 4% (mass fraction).

[0039] (b) Press the green body powder obtained in step (a) into a ceramic green body by a press, the pressing pressure is 30MPa, and the holding time is 6s.

[0040] (c) The ceramic green b...

Abstract

The invention provides a fragrant ceramic decorative plate and a preparation method thereof. The fragrant ceramic decorative plate is obtained by infiltrating a solid fragrant substance into a porousceramic plate through a melt impregnation process; and the porous ceramic plate is prepared from kaolin, calcined bauxite, a mineralizing agent, a sintering aid and a reinforcing agent. The preparation method of the fragrant ceramic decorative plate comprises the steps of ball milling, spray drying, compression molding, first firing, ink-jet printing and glazing, second firing, fragrance infiltration and surface treatment. The high-strength and high-porosity ceramic plate is prepared under the condition of no pore-forming agent by virtue of the enhancement effect of in-situ synthesized mullitewhiskers, a storage carrier with excellent performance is provided for fragrance substances, and the defect of low strength of a traditional fragrance ceramic carrier is overcome; and solid fragrancesubstances are infiltrated and surface treatment is performed through melt impregnation operation, so that a large amount of fragrance can be stored and slowly released, and lasting release of the fragrance is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of architectural ceramic decoration, and mainly relates to a durable fragrance ceramic decorative plate and a preparation method thereof. Background technique [0002] As an excellent building decoration material, ceramic tile occupies an important position in people's home life, but the production process also consumes a lot of mineral raw materials and energy such as clay, sand and stone. To reduce the consumption of raw materials and energy, in addition, the same purpose can also be achieved by reducing the bulk density of ceramic tiles, that is, reducing the transportation and installation costs of products, and expanding the application fields of ceramic tile products (such as high-rise buildings, lightweight door panels cabinets, etc.). [0003] There are various methods to prepare lightweight porous ceramics, such as particle packing method, pore former method, extrusion molding method, foam impregna...
