Description

METHOD OF FORMING ANTIMICROBIAL LAYER AND PRODUCTS OBTAINED
WITH THIS METHOD
DESCRIPTION
THE RELATED ART The invention relates to coating of glass, ceramic, metal (stainless steel, aluminium, brass etc.) and so on with substances comprising silver, copper, zinc, or titanium with antimicrobial activity during or after production.
BACKGROUND OF THE INVENTION
In our day, wherein consumption has reached massive scale as a result of socialization of humanity, especially commercialization of human and animal food with increasing intensity has brought along microbic pollution. Various studies have been made within the last 20 years in order to prevent proliferation of diseases caused by microbes. Therefore, various materials are provided with characteristics that do not permit living of microbes via various tools and methods. Most significant ones among these comprise providing antimicrobial characteristics by making use of silver, zinc, titanium etc. metals.
Providing antimicrobial characteristics to the material being produced by means of adding the said active antimicrobial substances in certain ratios brings about significant problems. In order to provide adequate antimicrobial effect by addition of antimicrobial material obtained by a valuable metal such as silver, it has to be added in the ratio of 0.1 percent to 8 percent of the product weight. The most significant disadvantage of such an application is addition of antibacterial silver or similar antibacterial material in the rate of 0.1 percent to 8 percent of the total product weight. On the other hand, as a result of adding antimicrobial material, undesired characteristics may occur in some products due to the own characteristics of the products. For instance, in ceramic, porcelain etc. products, antimicrobial material added into glazing leads to colour change in glazing. In addition, it is known that antimicrobial material found in glazing degenerates in porcelain fired in high temperatures. In glass products, which are both used as household goods a\
limitations are found in antibacterial product usage due to the intrinsic characteristics of glass. These limitations can be listed as follows: first of all, both cup, dishes etc. household goods and bottle, jar etc. goods used as storage containers or packaging materials are relatively cheaper products than other ones. Therefore, addition of high cost antimicrobial material into the product constitution with 0.1 to 8 percent by weight ratio would cause significant increase in product cost. One of the solutions developed for overcoming this problem is disclosed in USA patent document no 6,797,278 B2 as coating antimicrobial material on the product via sol-gel method at low temperature. However, again a significant increase of cost is observed. With this method, an additional process is required in the production procedure of glass household goods or glass packaging materials. And this will naturally be a separate cost component.
Another limitation which couldn't be solved in antimicrobial coating methods is repeated washing of cup, dishes etc. glass household goods with basic detergents at high temperatures. Coatings that do not integrate with the glass surface lose their antimicrobial characteristics as a result of the chemical impact of the detergent and being exposed to high temperatures.
With the present invention, cheap, effective, and permanent antimicrobial coating is provided on cup, dishes etc. glass household goods used on tabletop or food storage container or bottle jar etc. can or packaging materials of beverage or drug etc. products or glazed porcelain ceramic dishes etc. tabletop goods or sink, closet etc. health equipments, and effective solutions are brought to the above given limitations.
DESCRIPTION OF THE INVENTION The present invention relates to coating the surfaces of glass, ceramic, porcelain, and so on tabletop equipments and packaging materials made of glass, porcelain, and ceramic and tiling etc. products used as floor and wall tiling and closet, sink etc. health equipments by antimicrobial material via spray pirolysis method.
First of all, the antimicrobial solution material that would be used in the spray pirolysis method has to be prepared. For this, the antimicrobial material prepared by using; i) One or more of leachable antimicrobial silver (Ag), c«
metals in 0.1 percent to 8 percent ratio; ii) Non-leachable antimicrobial Ti02 part in 0 percent to 50 percent ratio; iii) One or more of Zr02 or AI2O3 as alkali resistant material in 0.1 percent to 40 percent ratio; iv) Acid resistant part and S1O2 in 2 percent to 94.5 percent ratio; and v) Stabilizer, acetonitrile, pyridine etc. and preferably acetonitrile comprising amine group to be bonded to silver with the purpose of eliminating the undesired colours formed due to presence of silver, is applied in solution form on hot glass, ceramic, porcelain etc. products via spraying, direct applying, or immersion etc. any other method.
Above said antimicrobial material has to comprise at least one leachable (Ag, Cu, or Zn) and/or optionally a non-leachable photo-active antimicrobial Ti02.
On the other hand, as mentioned above, since the products to gain antimicrobial characteristics are repeatedly washed with detergents, they have to be basic or acidic resistant. It has to comprise Si02 in order to gain acidic resistance; and Zr02 or AI2O3, preferably Zr02 for basic resistance.
Again, in order to prevent formation of nano-silver that gives colour to the solution and coating to be used, an organic substance comprising amine group that can be bonded to silver, preferably acetonitrile, has to be present.
For hot medium applications as functional agents, above said composition has to be prepared by being melted within; preferably methyl chloride and toluene having low combustible characteristics but high spontaneous combustion characteristics or water etc. organic solvents that do not have any combustion characteristics. Use of any solvent is suitable in cold applications. Said compound or solvents gain functionality by forming a metal oxide/metal layer on glass or porcelain etc. products and via melting of organic parts during contact in hot application and by means of an additional firing process in cold application. Said composition having antimicrobial characteristics is
production of glass or porcelain etc. household goods and packaging material. Application is made on hot or cold product via spraying or a similar method. After application on hot product, organic substances found within the composition melt with the impact of heat. In this way, a metal oxide or metal layer having antimicrobial characteristics is coated on the product. An additional firing process (between 200 C° and 600 C°) is required in the cold product.
For application of the said composition, the required temperature of the product has to be between 100 C° to 650 C°, but preferably between 125 C° to 550 C°. In cold medium coatings, product temperature has to be between 20 C° to 250 C°.
Said temperatures are applied in press-and-blow, press, blow-and-blow and IS (glass packaging machine) etc. machines before or after the packaging process.
Said molten composition comprising antimicrobial material can be applied via various methods. The main one of these methods is spraying method. Spraying method has the feature of easier and more effective application on the inner sides of glass products, such as the inner side of cups or storage containers or jars, bottle etc. products to be used as packaging materials. Other methods comprise direct application, spraying, and immersion on dishes etc. products via certain tools. However, methods listed here are only for exemplary purposes and are not restrictive.
In the same way, antimicrobial characteristics can be given to ceramic, porcelain household goods or health equipments via application of molten composition having antimicrobial characteristics by means of spraying or another method at the above said temperatures after being taken out of the furnace and thus leaving metal oxide/metal layer on the surface.
This method is not only limited to glass, ceramic, porcelain etc. household goods and health equipments, and it can be applied on metal (stainless, brass etc.) using the same method.
