Problems solved by technology

Although this process achieves the effect of hydrophobicity and improves the antifouling performance to a certain extent, due to the low synthesis temperature, the film layer is easy to fall off and the wear resistance is poor.

Abstract

The invention relates to a self-cleaning sanitary ware glaze with hydrophobic property and a preparation method thereof. The self-cleaning sanitary ware graze comprises ground graze and cover glaze and is characterized in that: the cover glaze is added with fluoride and titanium oxide; refinement is done to the grain size of the glaze material which is burned at a time under the temperature of 1150 to 1300 DEG C, thus obtaining the self-cleaning sanitary ware glaze. The self-cleaning sanitary ware glaze of the invention has the advantage of ensuring the prepared sanitary ware has lucent and clean surfaces and lasting self-clean effect and the surfaces of the sanitary ware are easily cleaned with stain resistant.

Description

technical field [0001] The invention relates to a porcelain or stoneware sanitary ware glaze, in particular to a self-cleaning sanitary ware glaze with hydrophobic function and a preparation method thereof. Background technique [0002] Sanitary ware is widely used in daily life due to its beauty, practicality and other advantages. Although the glaze layer on the surface of the sanitary ware is quite dense and smooth, due to the limitation of the production process, there are still tiny pinholes and unevenness on the surface, which makes it contact with some pollutants during use, such as urine and urine. , Scale, urine scale, soap foam, fatty acid, amino acid, etc., under the action of various physical or chemical forces such as van der Waals force, capillary force, hydrogen bond, etc., are easy to accumulate on the unevenness of the surface of the sanitary ware or enter the micropores, resulting in sanitary ware pollution. The pollution on the surface of sanitary ware no...
