Problems solved by technology

[0003] Because silver can sterilize and prevent bacteria from accumulating, it can prevent the spread of bacteria and prevent infectious bacteria. Therefore, people try to use silver to sterilize bacteria, such as plastic bottle caps with nano-silver, plastic bottles, plastic bottle cap gaskets, etc., but These products alone are not enough to prevent the spread of germs in public places. To prevent the spread of bacteria or germs in public places, the use of building materials with bactericidal functions (such as automatic sterilization and disinfection ceramics, etc.) is a good way
There is no automatic sterilization and disinfection ceramic product in the prior art

specific Embodiment 1

[0031] This embodiment consists of a ceramic toilet body and a nano-silver glaze layer sprayed on the surface of the body. The glaze layer is composed of non-toxic nano-silver and enamel, and the weight percentage of nano-silver and enamel liquid is 1:840. Non-toxic nano-silver can be in powder form or ion aqueous solution. The thickness of the nano-silver glaze layer is 0.7-1.2mm.

[0032] The manufacturing method of the present embodiment is as follows:

[0033] The first step is to select a number of qualified ceramic body toilets, and carry out the conventional treatment before glaze spraying, and wait for use;

[0034] The second step is to mix the sterilized glaze liquid: put 12 kg of clear water in a cleaned plastic bucket, and accurately pour 15 ml of nano-silver aqueous solution with a concentration of 33%. After the nano-silver aqueous solution is dissolved in water for 17 minutes, pour it into the aqueous solution Infiltrate 30 kg of enamel into the medium, stir m...

specific Embodiment 2

[0038] This embodiment is composed of a ceramic wall tile body and a nano-silver glaze layer sprayed on the body. The glaze layer is composed of non-toxic nano-silver and enamel. The weight percentage of nano-silver and enamel liquid is 1:500. The non-toxic Toxic nano-silver can be powder or ion aqueous solution. The thickness of the nano silver glaze layer is 0.1mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm or 0.7mm.

[0039] The manufacturing method of the present embodiment is as follows:

[0040] The first step is to select qualified ceramic wall tile body, carry out routine treatment before glaze spraying, and wait for use;

[0041] The second step is to mix the sterilized glaze liquid: use a clean plastic bucket to fill the spare water, and accurately pour the nano-silver aqueous solution with a concentration of 25%. After the nano-silver aqueous solution is fully dissolved in the water, it will penetrate into the enamel according to the proportion , making the weight percentage of n...

specific Embodiment 3

[0045] This embodiment consists of a ceramic floor tile body and a nano-silver glaze layer sprayed on the body. The glaze layer is composed of non-toxic nano-silver and enamel. The weight percentage of nano-silver and enamel liquid is 1:1000. The non-toxic Toxic nano-silver can be powder or ion aqueous solution. The thickness of the nano silver glaze layer is 0.8mm, 0.9mm, 1.0mm, 1.1mm or 1.2mm.

[0046] The manufacturing method of the present embodiment is as follows:

[0047] The first step is to select qualified ceramic floor tile body, and carry out routine treatment before glaze spraying, and then use it;

[0048] The second step is to mix the sterilized glaze liquid: use a clean plastic bucket to fill the spare water, and accurately pour the nano-silver aqueous solution with a concentration of 40%. After the nano-silver aqueous solution is fully dissolved in the water, it will penetrate into the enamel in proportion , making the weight percentage of nano-silver and ena...

Abstract

A sterilizing and disinfecting nano-Ag ceramic materials used for decoration of building, brick, bathtub, flushing toilet, life tools and dining utensils to prevent infectious diseases including fowl's influenza, SARS, etc is prepared from raw ceramic body through preparing enamel from non-toxic nano-Ag and ceramic enamel proportionally, and spraying it on the surface of said raw ceramic body.

Description

technical field [0001] The invention relates to a nano-silver sterilizing and disinfecting ceramic and its manufacturing method and application, which can be used to make various ceramic products such as ceramic tiles and sanitary ware, and has the function of permanent automatic sterilization. It belongs to the technical field of ceramic products. Background technique [0002] At present, ceramic products are popular among consumers because of their durability, smooth and beautiful surface. In crowded public event places such as stations, airports, schools, hotels, hotels, and large conference venues, ceramic products such as floors, walls, sanitary ware, toilets, etc. are easily contaminated with germs and need to be sterilized manually. After the battle against SAR in 2003, people knew the importance of public health. But how to clean and what aspects to clean to avoid the proliferation of bacteria, generally speaking, should start from the aspects of family hygiene and...
