Description

Antibacterial ceramics and its manufacturing method {The Boric Acid Ware Manutacture With iS Poredpottory Omtibacteria And Zinc Oxide}

The present invention relates to an antimicrobial ceramics and a method of manufacturing the same, and more particularly, to provide an antimicrobial ceramics using boric acid, zinc oxide, and silver having excellent antibacterial properties and stability that does not change even at high temperatures.

Generally, products with antimicrobial function made by using antibacterial agent are widely used in various household goods such as textiles, plastics and paper, but antibacterial treatment for products such as tableware and various silverware (toilet toilet, bathroom tiles, etc.) containing food Many pathogens are inhabited because they could not.

That is, in the case of porcelain, because it is fired at a high temperature of 1300 ℃ or more, when the antimicrobial treatment using the general antimicrobial agent in the process of baking the porcelain at a high temperature, the antibacterial agent burned or the physical properties were changed to prevent the antibacterial treatment.

In order to solve this problem, the present invention is an antibacterial treatment using boric acid, zinc oxide and silver having excellent antibacterial properties and stability that does not change even at high temperature, but dissolves boric acid in water and synthesizes the boric acid solution with a silver colloidal solution. Subsequently, the synthetic solution was synthesized in zinc oxide and replaced with a semi-solid length. The antimicrobial powder was then prepared by drying and pulverizing the antimicrobial powder. It was made possible.

The antimicrobial ceramics of the present invention are prepared using boric acid, zinc oxide, and silver having excellent antibacterial properties and stable properties that do not change even at high temperatures.

Boric acid, a bactericidal and antiseptic effect, is a colorless, glossy flake powder that is soluble in water, but becomes pyroboric acid (H ₂ B ₂ O ₇ ) at temperatures above 160 ° C and boric anhydride (B) at high temperatures. ₂ O ₃ ) was used because it does not burn or change its physical properties even when the ceramics are fired at a high temperature of more than 1300 ℃.

Zinc oxide; Also known as zinc oxide (zinc oxide), silver is next to the excellent antibacterial and high stability. The zinc oxide is white powder, yellow when heated, and becomes white again when cooled. Specific gravity is 5.47 ~ 5.61, melting point is 1800 ℃, excellent in coloring power, insoluble in water and adsorbing carbon dioxide gas. It has a high melting point of 1800 ℃, so ceramics are used at high temperature above 1300 ℃ because their physical properties do not change and their stability is the same.

Silver; It is widely used as an antimicrobial agent because of its high antimicrobial activity and stability. The silver colloidal solution containing silver was synthesized with boric acid and substituted with zinc oxide, thereby greatly improving the antimicrobial activity of zinc oxide.

Antibacterial ceramic production method of the present invention using the antimicrobial agent as described above,

A boric acid dissolution step of dissolving 500 g of boric acid in 1,000 ml of water, a process of synthesizing the boric acid solution and silver colloidal solution for synthesizing the boric acid solution into 100 ml of a silver colloidal solution containing 50% silver solids;

Semi-solid substitution process of synthesizing the fixed synthetic solution with 2,000 g of zinc oxide to make a semi-solid length, antimicrobial powder manufacturing process made by drying and grinding the semi-solid length, and the antimicrobial powder 10 to 25% by weight in ceramic glaze Antibacterial glaze obtained by synthetic stirring at a ratio is coated on ceramics and fired to manufacture antimicrobial ceramics.

The antimicrobial ceramic preparation example of the present invention manufactured as described above is as follows.

(Example)

-Antibacterial Powder Manufacturing-

First step

500 g of boric acid is dissolved in 1000 ml of water to form a boric acid solution.

2nd step

100 ml of a silver colloidal solution containing 50% of the solid content of the boric acid solution is prepared.

3rd step

The boric acid solution of the first step and the silver colloidal solution of the second step are synthesized and stirred evenly.

4th step

Synthesizing the three phases of the synthesis solution with 2,000 g of zinc oxide to create a semi-solid length.

5th step

The semi-solid length that passed through the four steps is heated and dried at a temperature of 100 using a simple dryer.

6th step

Disintegrating and grinding the five stages of heat drying and semi-solid length to prepare an antimicrobial powder.-Manufacture of porcelain-Step 1 Put 500 g of the antimicrobial powder in porcelain glaze into 1000 ml of porcelain glaze and stir it to dissolve it. The second step ceramics or various ceramics are immersed in the antimicrobial glaze of the first stage and then dried.The third step, pottery coated with the antimicrobial glaze in the second stage is put into a kiln and plasticized to produce antimicrobial ceramics. The antimicrobial ceramics of the present invention have the antimicrobial functions of boric acid, zinc oxide, and silver on the surface of porcelain, which prevents mycelial bacteria, Escherichia coli, and agrobacteria.

As described above, the present invention is excellent in antimicrobial properties and does not change even at high temperatures, and thus it is possible to manufacture antimicrobial ceramics using boric acid, zinc oxide and silver having stability. Such antimicrobial ceramics are inhabited by various germs as well as various tableware containing general food. And it is very hygienic can be used to apply to various ceramics, such as bathroom toilet bowl and bathroom tiles are not good hygiene.
