Preparation method of photosensitive self-cleaning antibacterial ceramic

Abstract

The invention discloses a preparation method of a photosensitive self-cleaning antibacterial ceramic. The preparation method comprises following steps: A, material preparation; B, pulping; C, pulverizing; D, compression moulding; E, drying; F, glazing; and G, sintering. The preparation method is safe and convenient; the prepared photosensitive self-cleaning antibacterial ceramic is capable of preventing or inhibiting growth and breeding of bacteria or pathogenic microorganism on ceramic surfaces, and reducing pathogenic microorganism propagation and infection rate.

Description

technical field [0001] The invention relates to the technical field of ceramic processing, in particular to a preparation method of photosensitive self-cleaning and antibacterial ceramics. Background technique [0002] Ceramics for daily use are widely used in daily life due to their beauty and practicality. Although the glaze layer on its surface 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 some pollutants in contact with it during use. Under the action of various physical or chemical forces such as capillary force, hydrogen bond, etc., it is easy to accumulate on the unevenness of its surface or enter the micropores to cause health hazards. Although there are self-cleaning ceramics on the market now, it is only by further adjusting the density of the glaze to achieve the effect of easy cleaning. However, these pollutants will also lead to a large number of microorganism...

Problems solved by technology

Although the glaze layer on its surface 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 some pollutants in contact with it during use. Under the action of various physical or chemical forces such as capillary force, hydrogen bond, etc., it is easy to accumulate on the unevenness of its surface or enter the micropores to cause health hazards

Although there are self-cleaning ceramics on the market now, it is only by further adjusting the density of the glaze to achieve the effect of easy cleaning. However, these pollutants will also lead to a large number of microorganisms such as bacteria on the surface of daily-use ceramics. Threat to user's health

Therefore, the current self-cleaning ceramics cannot meet people's requirements for high-quality life.
