Abstract
The invention discloses a sanitary ceramicglaze with a colorful effect. The sanitary ceramicglaze mainly comprises the following raw materials in percentage by weight: 16%-28% of quartz, 18%-27% ofpotassium feldspar, 0.4%-0.8% of dolomite, 3%-4% of kaolin, 3.2%-4.2% of zincoxide, 9%-11% of aluminum oxide, 9.5%-11.5% of zirconiumsilicate and 15%-30% of wollastonite. Correspondingly, the invention further discloses a preparation method of the sanitary ceramicglaze with a colorful effect, and a sanitary ceramic. The Vickers hardness of the sanitary ceramic glaze surface can be effectively improved, and meanwhile, the glaze surface has a colorful flashing effect under the irradiation of lamplight and has an outstanding decorative function.
Description
technical field [0001] The invention relates to the technical field of sanitary ceramic glazes, in particular to a sanitary ceramic glaze with colorful effects, a preparation method thereof, and sanitary ceramics. Background technique [0002] The glazed surface of existing sanitary ceramics is mainly based on bright glazed surface, and the decorative effect is relatively poor. At the same time, the existing sanitary ceramic glazes have relatively low hardness, are easily scratched during use, and are difficult to clean after scratches and dirt are absorbed. [0003] On the other hand, in the field of glazes, a common glaze is crystalline glaze, which adds 15-20% crystallization agents to the glaze, and after high-temperature melting, these crystallization agents can form a supersaturated melt. During the cooling process, crystals with a particle size of more than 10 μm are precipitated to achieve the purpose of decoration. Common crystallization agents such as zincoxide,...
