Detailed description of the silver and silver nano (20) which is a constituent of the present invention in order to help understanding of the present invention is as follows.

    Nanotechnology is a technology that identifies and controls substances at the molecular and atomic levels.It comes from the Greek word dwarf, lanose, and 1 nanometer 'corresponds to one-tenth of the thickness of the hair. It is made of silver solution (colloid), which is a chemical decomposition method or a fine particle state in nano units, and is widely used in industrial fields.

Silver, the main ingredient of Nano silver, has been recognized as a precious metal of high value from ancient times, and has been the object of collection, and it is recognized as an important industrial material in modern industry as well as its value as money. The production of silver is proportional to the production of gold in many ways.

Silver was mined early in Europe's Mediterranean coast, where silver was produced from the Incas and Aztecs before the discovery of the Americas, and then silver from Peru and Bolivia entered Europe and flowed out from 1520 to 1800.

It has grown steadily, but has declined since the discovery of large amounts of silver in the early 19th century.

Currently, the world's major silver producers are Russia (13.8%), Canada (13.5%), Mexico (13%), Peru (13%), United States (11%), Australia (8%), Poland (6%). The country's silver reserves are 17 million tons, and its mining capacity is about 1.2 million tons. As of 2002, silver produced in Korea is about 5,000 kg, which accounts for 1.2% of the total domestic demand. The amount is so small that the rest of the silver is imported from abroad.

Characteristics of silver: The color of silver is gray in the case of elegant gray-white metal or powder, specific gravity is 10-12, Mohs hardness is 2.5-3, melting point 280 is 960.5 ℃.

In particular, the melting point (280) of silver is very important for the temperature compensation of high thermometers, and it is the standard of scientific and industrial temperature. Silver is the best conductor of metal, and is used comprehensively for mechanical contacts and other electronics. .

Silver is optically 90% of visible light, which is one of the best metals such as platinum, and silver does not rust even when left in the air or heated (190), but it reacts with sulfur and hydrogen sulfide to emulsify it. Silver is made and turns black.

     In addition, the mechanical properties change according to the amount of impurities (O₂) contained in the silver, and the hardness of the high-purity silver obtained by thermal annealing is Brinell hardness HBS (10/500) 25-27, tensile strength 12-16kgf / mm2. The cast strength of the cast was up to about 29 kgf / mm 2, the combustion rate was 48 to 54%, and the recrystallization temperature was 150 ° C.

    Particularly, in the case of pure silver, the processed hardened material is softened by recrystallization at normal room temperature (400), and the malleability and flexibility are abundant next to gold.

     The effect of silver has been used as a tool to check the imbalance of the body that one cannot feel because the gloss or color changes depending on the condition of the body when worn on the body from ancient times. If you are tired or have low rhythm), Dongbobom is effective in the prevention and treatment of mental disorders and women's diseases such as epilepsy and game. If you have it, the five Jang (5 하고) is comfortable, mind and body (stable), the mind and body ((身 身) stable), chasing (邪氣) and the body lightens the body lengthened by the main tree.

      Also, when the Black Plague prevailed in the Middle Ages, nobility of the black aristocrats and royals, who had many silverware and silver utensils, did not have black plague, which released silver to the extent that it was able to sterilize the Black Plague bacteria, making it relatively safe from infectious diseases. In the place where the royal family and the state guests were served, silver products were used habitually.

In order to help the understanding of the silver nano (20) briefly described the silver nano (20) (Nano silver) extraction method and features in the present invention as follows.

The atomic weight of silver is 107.87 amu and the fact that silver (Ag) is bactericidal has been known for a long time.

Silver nano (20) was first developed by a biotechnology company, a government-affiliated organization in our country, and was named silver nano (20) as a compound name of the brand name Na no-technology and silver. ;

  Silver nano (20) is a field of Na no-technology, which is an advanced antimicrobial agent that uses silver's strong antibacterial and sterilizing function and electromagnetic shielding mechanism. Silver nano (20) is unlikely to be resistant to bacteria, unlike conventional antibiotics. Silver nano (20) has been shown to kill almost all single cell germs on the ground in a short time. .

 Currently, a variety of products based on silver nano (20) consisting of powder and solution have been devised and produced in real life. This technology, called silver nano (20), uses silver nanometer (1 billion won). It refers to a small particle size of 1m / min), that is, 0.000000001m. When one gram of silver is aged, ten particles can be produced.

Therefore, silver silver (Age) is a new concept that is made by using excellent effects such as anti-bacterial, deodorizing power, and extended food preservation time among many characteristics of silver. .

 Since ancient times, silver has been recognized as a disinfecting material that not only prevents bacteria but also East and West. Currently, the extraction method of silver (20) (Age 99.9%) is added to distilled water. It generates low current at low temperature, electrolyzes compounds containing silver, and conducts electrophoresis using + and-poles of each molecule to collect silver (Age 99.9%). In addition, liquid reduction and grinding In order to obtain a stable silver nano (20) (Nano silver), many conventional electrolysis methods are used, and various known forms of nano silver are well known.

The production of nano silver has been released in various ways, and good methods are being developed and developed one after another. Conventional nano powder production methods can be divided into gas phase method, liquid phase method and mechanical method. Law and meteorological reduction method, and mechanical grinding method using mechanical force.

The uniformity of the particle size of the prepared powder is good and can produce particles of high purity, and the advantages and disadvantages of preventing the agglomeration of the particles have the disadvantage that the experimental equipment is expensive.

In addition, the manufacturing method using the liquid phase is capable of producing a uniform powder than the manufacturing method using the gas phase, and also has the advantage of manufacturing the powder at a low device cost, but the tendency of aggregation of the individual particles is very strong and the shape of the particles is somewhat irregular The disadvantage is that.

Next, there is a systematic recipe,

While there is a problem in the incorporation of impurities generated in the manufacturing process and a severe condensation phenomenon, there is an advantage that can easily mix several components,

In the present invention, the present invention is characterized in that it does not produce silver nano in accordance with the production method of silver nano, but applies the conventional silver nano produced through the various types of silver nano production in the present application to make a product.

The silver nano 20 of the present invention is a fine particle of silver having a particle diameter of 0.1 to 50 nm, which directly acts on harmful bacteria, directly dissolves the cell membranes of harmful bacteria, and sterilizes by disrupting the electron transfer system of harmful bacteria. It has antibacterial and antibacterial properties (99.9%) (reference virus size is about 10 nm).

     The main antimicrobial mechanism of silver nano (20) is to dissolve harmful bacteria cell membranes and interact with enzymes in the cells to block the metabolic function of nutrients, ie, the influx and discharge of nutrients, and to stop the respiratory function and production of harmful bacteria. And destroys regenerating ability to kill harmful bacteria.

     In addition, the silver nano (20) by controlling the harmful bacteria by releasing the antimicrobial power continuously from the fine particles is excellent in the antimicrobial, antimicrobial sustainability.

Therefore, silver nano (20) does not produce resistance and silver nano (20) is effective to perform a surface reaction and kill all the germs 99%, particularly effective in the general E. coli or food poisoning.

   The smaller the nanoparticles, the better the bactericidal and antimicrobial activity. Based on the experimental data so far, Escherichia coli, Staphylococcus aureus, Salmonella, Vibrio bacillus, Heterogeneous bacteria, Pneumococcus, Typhoid bacillus and the most resistant MRSA Resistant Staphylococcus aureus) can be 99.9% antibacterial and sterilized.

     Even if silver exists in an ionic state or a metal state, it can be referred to as colloidal silver if it exists in a colloidal state by a solvent.

In silver nano (20) (Nano silver) is the best antibacterial silver nano particles (20) minimized.

   In addition, unlike the general chemical antibacterial or chlorine disinfectant, silver nano (20) is a pure silver ultra fine particle, has excellent antibacterial and bactericidal zone (99.9%) even at high temperature, non-toxic and non-irritating to the human body, bacteria and E. coli virus fungus It has been reported that bacteria cannot live in contact with silver nano 20 for more than 5 minutes.

As described above, silver nano 20 material or fragrance agent is added to the coating 200 film made of the various materials, and the coating 200 or the mixture 180 is used to attach bacteria and harmful substances to the film body 10. It relates to a functional coating film 10 containing silver nano 20 and fragrance agent 40 for anti-sterilizing the material, blocking ultraviolet rays and emitting good ions and far infrared rays to the body;
