Problems solved by technology

A layer of glassy glaze is coated on the fired blank, mainly for protection and decoration, but the existing washing liquids contain alkaline builders, defoamers, oxidants, surfactants and Thickeners, etc., are highly corrosive to the surface of ceramic products, and will cause surface damage, such as fading, white turbidity, halo, corrosion marks, etc., which seriously affect their repeated use and increase the cost of use. , so now there is a need for a preparation process of grinding and adding silica sol to prepare high alkali-resistant ceramic overglaze color solvent

Abstract

The invention provides a high-alkali-resistance ceramic overglaze color solvent prepared by grinding silica sol. The material comprises the following materials in percentage by weight: 17%-25% of feldspar, 40%-50% of borax, 6%-12% of kaolin, 8%-13% of aluminum oxide, 2%-5% of lithium carbonate, 2%-5% of potassium carbonate, 1%-3% of soda, 4%-8% of calcium carbonate, 0.5%-1% of niobium pentoxide and 2.5%-5% of tantalum pentoxide. The preparation method has the beneficial effects that a special heat treatment system is carried out on aluminum, boron and various oxides to prepare the ceramic overglaze color solvent which is excellent in alkali resistance and suitable for a dish-washing machine, and the silica sol is used for preparing the high-alkali-resistance ceramic overglaze color solvent, so that the quality of domestic daily ceramics can be remarkably improved, and remarkable economic benefits are achieved; by adopting a method of grinding the silica sol, flux ingredients can be melted at a lower temperature, and the silica sol and the flux are supplemented in a matched manner according to different proportions, so that a glass network structure is more compact.

Description

technical field [0001] The invention relates to a preparation process for preparing a highly alkali-resistant ceramic overglaze color solvent by grinding and adding silica sol, and belongs to the field of ceramic overglaze fluxes. Background technique [0002] At present, porcelain is a kind of utensil composed of porcelain stone, kaolin, etc., glazed or painted on the outside, and is impermeable. Because of its relatively low cost and wear-resistant and impermeable characteristics, it is widely used by people all over the world. Ceramic glazing refers to the so-called method that when firing porcelain, the blank should be fired first, and then it should be taken out to be glazed, and then fired. A layer of glassy glaze is coated on the fired blank, mainly for protection and decoration, but the existing washing liquids contain alkaline builders, defoamers, oxidants, surfactants and Thickeners, etc., are highly corrosive to the surface of ceramic products, and will cause sur...
