A wear-resistant glaze for preparing sanitary ceramics and a method for preparing sanitary ceramics

Abstract

The invention discloses a wear-resistant glaze for preparing sanitary ceramics, which comprises the following components according to mass percentage: 24-28% of quartz, 20-32% of feldspar, 6-13% of wollastonite, and 8% of zirconium silicate ~12%, Suzhou soil 5~10%, calcite 5~10%, zinc oxide 2~5%, corundum 2~5%, frit 2~5%, dolomite 2~5%, calcined talc 2~5% And methyl cellulose 0.2 ~ 0.5%. A kind of wear-resistant glaze for preparing sanitary ceramics proposed by this technical solution, adjust the usage amount of feldspar and wollastonite to improve the Al / Si ratio of formula components, and increase the raw materials zinc oxide and burnt talc to improve wear resistance The ratio of zirconium silicate and zirconium silicate can reduce the glaze wear of sanitary ceramics as a whole and improve the gloss. Furthermore, a method for preparing sanitary ceramics using the above-mentioned wear-resistant glaze for preparing sanitary ceramics is proposed, so that the surface of the manufactured sanitary ceramics is smooth and fine, the average amount of wear on the glaze is reduced to 70-80 mg, and the wear resistance High, long service life, its gloss is as high as 95 ~ 105GU.

Description

technical field [0001] The invention relates to the technical field of sanitary ceramics, in particular to a wear-resistant glaze for preparing sanitary ceramics and a method for preparing sanitary ceramics. Background technique [0002] In recent years, with the improvement of consumers' demand level, not only the requirements for smooth surface, beautiful appearance and self-cleaning effect of sanitary ceramic products have been improved, but also higher requirements have been put forward for the use characteristics of products. For sanitary ceramic products such as squatting pans, toilets and washbasins, in the process of daily use and cleaning and scrubbing, due to the frequent wear and tear on the contact surfaces of the products, it is easy to reduce the gloss of the glaze and lighten the color, causing dirt to infiltrate and bacteria to multiply. Seriously shorten the service life of sanitary ceramics. [0003] For the existing glazed surface of sanitary ceramics, th...

Problems solved by technology

For sanitary ceramic products such as squatting pans, toilets and washbasins, in the process of daily use and cleaning and scrubbing, due to the frequent wear and tear on the contact surfaces of the products, it is easy to reduce the gloss of the glaze and lighten the color, causing dirt to infiltrate and bacteria to multiply. Seriously shorten the service life of sanitary ceramics

[0003] For the existing glazed surface of sanitary ceramics, the wear resistance of the glazed tile surface is measured according to the test method of GB / T3810.7-2016 ceramic tiles. The degree of wear is 85-92GU, but the glazed surface in this wear range is still prone to wear marks and dirt during daily use, which is far from meeting the wear and gloss requirements of sanitary ceramic glazed surfaces
