Abstract

PURPOSE: An antibacterial agent prepared by substituting zinc carbonate for silver is provided which has high antibacterial effect, no toxicity and no heavy metals. Accordingly, the metallic antibacterial agent is applied to a glaze required for production of ceramics such as tiles, cups or ceramic wares. CONSTITUTION: The preparation of antibacterial agent comprises the steps of: dissolving ZnCl2 into alcohol in a weight ratio of 3:7; dissolving soda ash(Na2CO3) into water in a weight ratio of 2:5; mixing ZnCl2 solution with Na2CO3 solution to precipitate ZnCO3; washing and sintering at 600deg.C; substituting ZnCO3 for colloidal silver solution formed by electrolysis. Also, antibacterial ceramics are produced by soaking ceramics into glaze obtained by mixing 1000ml of glaze with 250g of prepared antibacterial agent, and sintering.

Description

Manufacture of porcelain antibiotics {The manutacture of poredpottory antibiotic}

The present invention relates to the production of antimicrobial ceramics. Zinc chloride is dissolved in alcohol, and soda ash is dissolved in water, and the zinc chloride solution and the soda ash solution are stirred and synthesized to obtain basic zinc carbonate. It is washed with water and calcined at 600 ° C to make powder powder. In addition, by electrolyzing silver to make a silver colloidal solution, the powder powder calcined at 600 ° C., dried and mixed to make a porcelain antimicrobial agent, the antimicrobial activity of the porcelain to the antimicrobial treatment by stirring and mixing the porcelain antimicrobial agent with porcelain fluid. The 99.9% effectiveness was determined by an accredited testing laboratory. As antibacterial agents, various kinds of antibacterial agents have been developed and marketed, but quaternary ammonium series antimicrobial agents cause genetic variation in the factor and prohibit their use. Metal antibacterial agents include silver, copper, and zinc chloride, but copper and zinc chloride cause a dielectric variation in the factor, and their use is prohibited. In addition, inorganic zinc is toxic and its use as a poison. Silver is widely used as an inorganic antibacterial agent because of its excellent stability, but its price is high. The present invention synthesizes zinc chloride and soda ash to make basic zinc carbonate and calcined at 600 ° to use silver as an antimicrobial metal having excellent stability and antimicrobial properties while electrolytically decomposing silver to make silver colloid, which is the main agent of the present invention. Pottery antibacterial agents were developed by substituting metal. Ceramics are fired at more than about 1300 ° C, so they cannot be used after burning quaternary ammonium-based antimicrobial agents or copper. Currently, various inorganic antibacterial agents are used for daily necessities such as textiles, plastics, and paper, but ceramic antimicrobial agents, which are used closely in our diet, have not been developed. It was confirmed that the present invention is excellent in thermal stability, harmless to printing, and excellent in antibacterial properties, even when burned at a high temperature.

In order to solve the above problems, zinc chloride has been used as a preservative for wood, but it is toxic and inorganic zinc is designated as a poison. The present invention synthesizes the zinc chloride with soda ash, etc. to make basic zinc carbonate, and then calcined at high heat to remove the toxicity and make the metal antibacterial agent to the factor, and to increase the antibacterial properties of silver colloidal solution by electrolysis of silver ingot antimicrobial Substituted in metal and synthesized in porcelain emulsion to provide excellent porcelain antimicrobial preparation.

A characteristic of the present invention for achieving the above object is to dissolve zinc chloride and alcohol in a mass ratio of 3: 7, and to mix and dissolve soda ash and water in a mass ratio of 2: 5, and to precipitate by mixing and stirring the zinc chloride solution soda ash solution. Basic zinc carbonate is produced. This is washed with water and fired in an electric furnace at 600 ° C. to obtain a powdered powdered metal antibacterial agent which is the main agent of the present invention. In addition, the electrolysis is put into a 500ml beaker and distilled water ㎖, as known, and then put the silver rods in the electrolysis to make a silver colloidal solution to replace the solution with the metal antimicrobial agent of the present invention to dry the metal antimicrobial excellent 99.9% of E. coli, Pseudomonas aeruginosa, and S. aureus were antibacterial to ceramics. An embodiment of the present invention having the characteristics as described above will be described in more detail below.

1st process

300 g of zinc chloride is quantified, and 1000 ml of alcohol is quantified, and zinc chloride is stirred to dissolve in alcohol.

2nd process

200 g of soda ash is quantified and soda ash is dissolved in 500 ml of water to make a soda ash solution.

3rd process

The chemical of the first process and the chemical of the second process are stirred for 20 minutes and precipitated for 1 hour.

4th process

The precipitate precipitated in the third step is washed.

5th process

The precipitate of the 4th process is put into an electric furnace, and it bakes to 600 degree centigrade.

6th process

After cooling the fifth process, powder powder can be obtained.

7th process

100 ml of distilled water is prepared in a 500 ml beaker.

8th process

Using a dry battery, weigh 20g of the silver bar in +-and put it in distilled water of the seventh step to be electrolyzed to dissolve silver in water to make silver collide.

9th process

The silver colloidal solution of the 8th process is substituted by 300 g of powder powder of the 6th process.

10th process

Dry mixing of the chemicals of the ninth step to produce a ceramic antimicrobial agent of the present invention.

11th process

1000 ml of porcelain emulsion was quantified, and 250 g of the antimicrobial agent of step 10 was stirred and mixed with the porcelain emulsion.

12th process

Pottery to be antimicrobial is immersed in the antimicrobial fluid of the 11th step to fire the ceramics to produce an antibacterial ceramic with excellent antibacterial power.

The antimicrobial agent according to the present invention as described above has excellent antimicrobial activity as a metal antimicrobial agent and has no toxicity and no heavy metals. Therefore, it is used to make toilets, water cups, bathroom ties, and various food storage bowls that are widely used by the public. It can prevent and also maintain the freshness when storing food and the like.
