Spray dry granular glaze for ceramic tile surface decoration and preparation method of spray dry granular glaze

Abstract

The invention discloses spray dry granular glaze for ceramic tile surface decoration. The raw materials comprise, by weight, 25-30 parts of potassium feldspar powder, 30-45 parts of albite powder, 8-10 parts of kaolin, 0-10 parts of calcite, 4-12 parts of wollastonite, 6-12 parts of dolomite, 4-8 parts of barium carbonate, 0-8 parts of zinc oxide, 0-8 parts of quartz powder, 0-7 parts of aluminum oxide, and 4-10 parts of resin used for enhancing the particle strength. The prepared dry granular glaze overcomes the defects of plasticity, flowability, environment, cost, particle strength and the like, particles of the prepared dry granular glaze are not melted or crushed, are smooth and round and have good flowability, kaolin is added into the formula, the plasticity is good, the strength of the particles is improved due to addition of resin, the particles cannot be dissolved in water, and the prepared dry granular glaze can be applied to the field of decoration. The prepared dry granular glaze is suitable for being applied to the surface of a ceramic tile together with glue, is also suitable for a blank-glaze integrated forming process, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a spray dry granular glaze used for surface decoration of ceramic tiles and a preparation method thereof. Background technique [0002] As a building decoration material, ceramic tiles have several surface decorations, such as non-decoration, polishing, and glazing. It is increasingly unable to meet people's needs, and the dry glazing and blank glaze integrated molding process with better texture and higher simulation degree came into being. In the dry glazing and blank glaze integrated molding process, a large number of dry granular glazes are used. At present, there are two main types of dry glazes used in ceramic production, one is frit dry granules, and the other is ordinary spray powder dry granules. Among them, frit dry granules can only be applied to the surface of ceramic tiles together with glue because of their lack of plasticity and poor fluidity. Or mixed with a sma...

[0002] As a building decoration material, ceramic tiles have several surface decorations, such as non-decoration, polishing, and glazing. It is increasingly unable to meet people's needs, and the dry glazing and blank glaze integrated molding process with better texture and higher simulation degree came into being. In the dry glazing and blank glaze integrated molding process, a large number of dry granular glazes are used. At present, there are two main types of dry glazes used in ceramic production, one is frit dry granules, and the other is ordinary spray powder dry granules. Among them, frit dry granules can only be applied to the surface of ceramic tiles together with glue because of their lack of plasticity and poor fluidity. Or mixed with a small amount of plastic glaze for the integral molding of the blank glaze, and the production of fritted dry granules has high production costs and environmental pollution problems. The low strength of the ordinary spray dry granulated glaze is not conducive to transportation and the shortcomings of water dissolution. also limits its application
