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

Example Embodiment

[0018] In order to make the purpose of the present invention and the advantages of the technical solution clearer, the following describes the present invention in further detail with reference to examples.

[0019] The preparation method of photosensitive self-cleaning antibacterial ceramics is characterized by comprising the following steps:

[0020] A. Ingredients: Weigh the raw materials of the green body according to the weight percentage, kaolin 10%, weathered sand 7%, potash feldspar 28%, low fire clay 32%, refined white sand 12%, waste green powder 4%, black talc 7%;

[0021] B. Pulping: Weigh the raw materials according to the ratio in A, and put the mixed raw materials into the ball mill according to the ratio of material: ball: water = 1:2:0.35; after ball milling, the ball mill forms a 250-mesh sieve with a balance of 1.2~ 1.7% slurry;

[0022] C. pulverizing: the slurry obtained in step B is made into powder through a spray dryer, and then aged for 2 to 3 days;

[0023] D....

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...
