Abstract

The invention relates to the technical field of functional ceramics, and discloses a preparation method of a ceramic coating layer with a long-lasting antibacterial function. The preparation method comprises the following steps: (1) preparing a coating layer spray solution: preparing a visible light-responsible modified TiO2 catalysis material, and compounding the TiO2 catalysis material with a thickener, a dispersant, a leveling agent and an antifoaming agent to prepare the coating layer spray solution; and (2) preparing the antibacterial ceramic coating layer: spraying the coating layer spray solution prepared in step (1) on the surface of a low temperature glaze, and carrying out pottery firing on the low temperature glaze at 300-1000 DEG C to prepare the antibacterial ceramic coating layer. A simple spraying process before the firing of the low temperature glaze is carried out to meet industrialization requirements and realize easy large-scale batch production, and an existing ceramic production process is simply adjusted to realize the industrialization upgrading of the ceramic production.

Description

technical field [0001] The invention relates to the technical field of functional ceramics, in particular to a method for preparing a ceramic coating with a long-acting antibacterial function. Background technique [0002] With the rapid development of economy and the rapid expansion of population, environmental pollution is becoming more and more serious. This provides a breeding space for the survival and reproduction of various harmful bacteria and viruses, and also creates favorable conditions for their mutation and rapid reproduction. All kinds of harmful bacteria can cause many diseases and have seriously endangered people's health. How to reduce and effectively prevent the impact and harm of various pathogenic microorganisms in the living environment on human life, and alleviate various infectious diseases caused by it has gradually become a social consensus, and people's demand for antibacterial materials and antibacterial products is increasingly strong.
