In addition, a sink consisting of the surface coating film of No. 20-0301554 is registered, which injects air gas and coating gas into the inner and outer surfaces of the stainless plate sink to coat the gold titanium coating layer. The above-described conventional invention as a sink is a technology that is completely different from the method of manufacturing a high hardness antimicrobial inorganic paint containing silver ions and a constitution paint coating on the sink.

The present invention is a water-soluble inorganic paint, using a variety of conventional inorganic coating paints, inorganic coating compositions, such as silver nano coating as coating agent or silver nano coating on cooking utensils using a variety of water in a conventional method It is manufactured by applying inorganic power to silver ions, phosphoric acid, manganese oxide, silicic acid, aluminum oxide, magnesium oxide, magnesium distilled water, and inorganic paints with high hardness and antibacterial properties. After the purpose of configuring the antimicrobial sink to the high hardness bacteria described in detail by the accompanying drawings as follows.

2 parts by weight of silver ionic agent (silver oxide) oxidized silver, 17-20 parts by weight of phosphoric acid, 3-5 parts by weight of aluminum oxide, 3-5 parts by weight of manganese oxide, 5-8 parts by weight of silicic acid, distilled water 60-70 parts by weight of the mixed composition to prepare a coating for coating coating the coating material prepared in the outer coating layer (5) and the outer surface of the sink (1) consisting of the periphery (2), the outlet (3) and the metal plate (4) It is characterized in that the coating layer 6 is coated with a thickness of 10 microns to form a film by firing the sink 1 coated with the paint in an electric furnace at a temperature of about 250 ° C. for 10 minutes.

The operation of the present invention thus described is as follows.

When the inner coating layer 5 and the outer coating layer 6 of the metal plate 4 of the sink 1 are coated with a thickness of 10 microns and installed on the sink of the kitchen, the hardness is 9H or higher even when the tableware, metal, glass, etc. collide. Strong, scratched, damaged, or peeled off, scratch-resistant without scratching, protects the inside and outside surfaces, sanitary by the antimicrobial power of silver ions to suppress the growth of various pathogens and bacteria, and prevents the occurrence of rust and scale. The same effect can be achieved by coating only the inner coating layer 5 of the metal plate 4 of the metal plate. The kitchen, especially the sinks for cooking and washing, are susceptible to environmental pollution, propagation of pathogens, bacteria, etc. If you don't pay attention, many new bacteria are developing and immunity against them is becoming more vulnerable. Sterilization is very important, and from the sink of the kitchen to cook food from the source, the surface treatment with antibacterial and sterilization has been an important task. As is well known, silver with antibacterial and sterilization has excellent antibacterial activity. It is well known that it has no influence on the human body and sterilizes 600 kinds of pathogens, removes fungi, and generates negative ions. However, the surface of the sink (1) contacted by alternating between cold and hot water (100 ℃) It is treated by oxidation, alteration and discoloration at high temperature around 100 ℃ to prevent the antibacterial activity from dropping, so as not to deteriorate the commerciality, and the paint produced by the above method is not only used for the sink (1) but also in bathtubs, sinks and other kitchen appliances and kitchen appliances. When used as a coating film, it has excellent antibacterial effect and robustness

The results of the antibacterial test and the hardness test of the metal plate 4 of the sink 1 formed by the method described above at the Korea Institute of Building Materials are as follows.
