These examples are only for illustrating the present invention in more detail, it will be apparent to those skilled in the art that the scope of the present invention is not limited by these examples in accordance with the gist of the present invention. .

The silver used in the three-coated kitchenware coated with silver powder according to the present invention belongs to group 1B of the periodic table, and the element symbol is Ag, the atomic weight is 107.868, and the melting point and the boiling point are 961.9 ° C., respectively, as one of the copper group elements. And 2212 ° C. The silver's malleability and ductility are so excellent that it is excellent in workability to make a silver foil with a thickness of 0.0015mm and a 1800m line with 1g of silver. The thermal conductivity of silver is the highest of all metals, 33% higher than copper, and the lowest electrical resistance of 8.4%. This silver has long been used as a disinfectant, silver cups have been used to prevent disease, and silver boxes have been used to prevent food spoilage. Recently, it has been used as silver soap, silver cosmetics, and silver yarns. Also, as silver tiles have appeared, they have been applied to jjimjilbangs, saunas, bathtubs, etc., and have received an absolute response. Therefore, this invention has the characteristic in the point which utilized the characteristic of this silver to the maximum.

On the other hand, the primer (primer) solvent used in the three-coated kitchen dish coated with silver powder according to an embodiment of the present invention is Teflon. Teflon is a registered trademark of DuPont, USA, and is a trade name of a fluorine carbide-based product having unique physical and chemical properties that other polymer compounds do not have. Types of Teflon include PTFE (Poly Tetra Fluoro Ethylene), FEP (Flourinated Ethylene Propylene), PFA (Per Fluoro Alkoxy), and ETEF. Among them, PTFE (Poly Tetra Fluoro Ethylene) is non-adhesive and usually forms a film with a primer and a top coating. This product exhibits higher heat resistance (290 ° C) than any fluorocarbon coating. It also features very low coefficient of friction, good wear resistance, chemical resistance and corrosion resistance. Primer solvent used in the silver-coated triple coating kitchen container according to the present invention is preferably PTFE, but is not limited thereto.

In addition, in an embodiment of the present invention, a mid solvent was used as PTFE (Poly Tetra Fluoro Ethylene) (DAIKIN product number EK-3709M-201). This solvent has a metallic black color, has a solid content of 45% (mass,%) and a viscosity of 100-250, and has excellent characteristics such as non-tackiness, durability, heat resistance, mold release, gloss and corrosion resistance. In addition, in one embodiment of the present invention, a top solvent was PTFE (Poly Tetra Fluoro Ethylene) (product number EK-3700-C201 manufactured by DAIKIN). This solvent is transparent, has a solid content of 45% (mass,%) and a viscosity of 100-250, and is characterized by excellent non-tackiness, durability, heat resistance, mold release property, gloss and corrosion resistance. Although the above solvents were used as the mid solvent or the top solvent, the solvent is not limited thereto.

Next, a method of coating a triple coated kitchen container coated with silver powder according to the present invention is as follows.

First, as a first coating step of coating Teflon PTFE (Poly Tetra Fluoro Ethylene) on the surface of the kitchen container with a primer solvent, the first coating layer 12 is formed by coating the surface 11 of the kitchen container. After that, the Teflon-coated first coating layer 12 is subjected to a first drying step of drying for about 20 to 40 minutes in a drying furnace of about 200 ~ 300 ℃. In order to facilitate mold release and sliding in the dried kitchen container, which has undergone the first drying step, a second coating step of coating a mid solvent is performed. The second coating layer 13 is formed on the first coating layer 12. After the step of forming a third coating layer 14 through a third coating step of coating by spraying a mixed solution mixed with a top solvent and a silver powder in the mid-coated kitchen vessel. The third coating layer 14 is preferably about 4 parts by weight to 40 parts by weight of silver powder per 100 parts by weight of the top solvent. When the silver powder is less than about 4 parts by weight, the silver powder is not densely applied to the second coating layer, and thus, it is difficult to prepare a kitchen container having a high antimicrobial, deodorizing function, and high conductivity, which is the object of the present invention. When it exceeds the weight part, since the adhesive strength with the second coating layer 13 is lowered, the coated silver powder may be peeled off, and the cost is increased due to the increased cost of the silver powder. Most preferred. On the other hand, the size of the silver powder is preferably 100 mesh (mesh) to 300 neck. If it is out of this size, the silver powder may be easily peeled off after the coating is completed. The third coating layer 14 formed through the third coating step is finally subjected to a step of drying for about 40 to 90 minutes in a drying furnace of about 400 ~ 450 ℃. What is important in this drying step is temperature and time. When the temperature is low or the time is short, the non-tackiness, hardness, wear resistance, corrosion resistance is poor, and when the temperature exceeds 450 ℃ or the drying time exceeds 90 minutes, the intrinsic color of silver discolors to a little yellow and the adhesion decreases. You must keep well. In addition, it is preferable that the coating thicknesses of the first coating layer 12 to the third coating layer 14 are all about 0.25 to 0.3 μm.

Meanwhile, according to another embodiment of the present invention, the top of the first coating layer 12 instead of the second coating layer 13 coated mid on the first coating layer 12 of the coating method. It is also preferred to use a second coating layer 13 coated with a mixed solution mixed with a solvent and a silver powder. In this case, the coating method must undergo a drying step of the third coating layer 14. Thereafter, the second coating layer 14 is coated on the top of the second coating layer 13 again with a mixed solution mixed with a silver powder and then coated again with a drying step. In the case of the embodiment according to the present invention coated in this way is to increase the antimicrobial effect and thermal conductivity and to further ensure the sliding function. In addition, in the preferred embodiment of the present invention, the mixed liquid of the second coating layer 13 and the mixed liquid of the third coating layer 14 are about 4 parts by weight to 40 parts by weight of silver powder per 100 parts by weight of the top solvent. It is preferable. In addition, the size of the silver powder is preferably 100 neck (mesh) to 300 neck.

As can be seen from FIG. 4 showing the surface of a triple coated kitchen vessel coated with silver powder according to an embodiment of the present invention coated in the above-described manner, compared to FIG. 3 showing the surface of a conventional frying pan, In the embodiment of the invention it can be seen that the silver powder is applied and evenly distributed.
