The present invention relates to a method for producing a ceramic powder, and more particularly, to prepare a powder that is a base material for far-infrared radiation made of aluminum oxide, magnesium oxide, zirconia, silicon dioxide, titanium dioxide, a binder, and the like By forming a thin film and antibacterial, anti-fungal treatment, far-infrared radiation, recovery of biopotential, antibacterial, anti-fungal action against all kinds of microorganisms parasitic on the skin can be used as a raw material of medicines or cosmetics.

In general, in normal cellular conditions without pain in the human body, sodium (+) ions in the extracellular fluid hold about 10 times the concentration of the intracellular fluid, and in electrical terms, the dermis of the skin is the sodium (+) ion in the extracellular fluid. It has a potential of 20 to 30 mV, and the epidermis also has a potential of 20 to 30 mV due to the charging phenomenon on the dermis.

Pain in various muscles is caused by a change in the membrane potential of the affected area (local) due to some cause such as a physical shock, so that the potential is temporarily reversed as sodium (+) ions are introduced into the cell.

Therefore, if electrons are sent to the epidermis of the affected part, the epidermis of the affected part is charged to the (-) potential and the dermis is charged to the (+) potential to maintain a normal state, but the current Pass do not emit enough electrons. The pain could not be removed.

Korean Laid-Open Patent Publication No. 1999-030380, which was devised to solve the above problems, relates to a `` parse composition, '' and at the same time, relieves pain by coating gold on a sintered body made of metal titanium and silicon. Although it was possible to reuse for years, there was a problem in that electrons were not sufficiently emitted only by mixing and sintering metal titanium and silicon, and Korean Patent Publication No. 174654, which is another prior application, described in the method of manufacturing silicon carbide ceramics having high fracture toughness. In this regard, titanium boride, which is a fracture toughness enhancer, was added to silicon carbide to prepare ceramics, thereby providing excellent fracture toughness, but there was a problem that did not help in treating the affected area.

In addition, 'Titanium-containing high functional water and its manufacturing method and apparatus' of Korean Patent Application Publication No. 2002-94001, which is another prior application, prepares water having a physiologically active function in which the molten titanium is dissolved, and is used to produce healthy water, health products, Although it was to be used as a medical product or cosmetics, but there is a problem that consumers do not want to buy because it is ingesting titanium, which is a metal material, and the health ornaments containing titanium powder of Korea Patent No. 415637, which is another pre-registered In the manufacturing method ', the titanium powder is blended with the elastomer material to manufacture health accessories. However, considering the properties of the titanium powder, which can emit electrons only when each particle is ionized, the utility value is remarkably significant in terms of electron emission. There was a minor problem that the health promotion effect was off.

Therefore, the present inventors invented the 'method of manufacturing a silicon carbide sintered body having a titanium ion thin film' of Korean Patent Application No. 10-2002-0027419, the prior application of the inventors is a carbonized pulverized into particles of a certain size The above problems have been solved by adding a sintering aid to the silicon powder and sintering, and depositing a titanium ion thin film on the surface of the sintered silicon carbide sintered body so that it can be attached to the affected area to solve the above problems. There is a problem that can not be used as a raw material of medicine or cosmetics because it does not have a wide range of applications due to the limitation as a solid.

Accordingly, an object of the present invention is to manufacture a powder which is a base material for far-infrared radiation made of aluminum oxide, magnesium oxide, zirconia, silicon dioxide, titanium dioxide, binder, etc. in order to solve the problems of the conventional ceramic material described above, Titanium ion thin film is formed on the powder, which is the basic material, and antibacterial and antifungal treatment is performed using silver ion colloidal solution to prevent far infrared radiation, recovery of biopotential, and antibacterial and antifungal action against all kinds of microorganisms parasitic on skin. It is to provide a method for producing a ceramic powder that can be used as a raw material of medicines or cosmetics.

Method for producing a ceramic powder of the present invention for achieving the above object,

Kneading 20-30 wt% aluminum oxide, 15-20 wt% magnesium oxide, 15-20 wt% zirconia, 10-15 wt% silicon dioxide, 25-35 wt% titanium dioxide and 3-8 wt% binder ,

Ball milling the kneaded kneaded material,

Removing water and drying the ball milled workpiece,

Firing the dried workpiece;

Pulverizing the fired plastic product,

Arranging the pulverized fired product in a deposition furnace to form a titanium ion thin film;

And spraying a silver ion colloidal solution on the fired product on which the titanium ion thin film is formed.

Hereinafter, the present invention will be described in detail.

First, aluminum oxides (Al ₂ O ₃ ), magnesium oxide (MgO), zirconia, silicon dioxide (SiO ₂ ), titanium dioxide (TiO ₂ ) and binders, which are harmless to the human body, are kneaded. It is preferable to knead for about 3 to 4 hours using a kneading machine of min and then to keep it at an atmospheric temperature of 10 to 30 ° C for 24 hours.

In addition, it is preferable to use clay or ocher which is harmless to the human body and is environmentally friendly as the binder.

The mixing ratio in the kneading is 20 to 30% by weight of aluminum oxide, 15 to 20% by weight of magnesium oxide, 15 to 20% by weight of zirconia, 10 to 15% by weight of silicon dioxide, 25 to 35% by weight of titanium dioxide and 3 to 8% by weight of binder. Aluminum oxide is preferably chemically stable and exhibits an emissivity of 93% or more compared to black body at room temperature, and zirconia and magnesium oxide are the main materials of this ceramic, which exhibits an emissivity of around 96.92% relative to black body. The content was formulated.

In addition, silicon dioxide and titanium dioxide are cosmetic raw materials, and the high content of titanium dioxide is due to its utility as a sunscreen.

After kneading, the kneaded kneaded product was ball milled, and the kneaded kneaded product was put into a ball mill, and 1.5 weight times of water of kneaded product added to the ball mill into which kneaded material was added was added, followed by 60 minutes for 72 hours. Process at a speed of ash / min.

At this time, the water is used water of 4 ~ 10 ℃, the ball used is calcined at 1400 ℃ or more, 30 to 50mm, white, the alumina component is used 90% or more.

When the ball mill processing is completed, the ball milled workpiece is dehydrated and dried.

At this time, the water is removed using a filter press, and the water-removed workpiece is dried for about 24 hours in a drying furnace at 150 to 200 ° C. If the drying temperature is less than 150 ℃, the drying time is long, the productivity is not good, if it exceeds 200 ℃ excessive heat amount takes economical economical is not good, so it is most preferable to dry at a temperature of 150 ~ 200 ℃ in consideration of productivity and economics However, this is not necessarily a limitation.

When the drying is completed, the dried workpiece is fired, and then fired for 30 to 34 hours at 1350 ° C. or higher, which is the required sintering temperature of the ceramic, using a gas fired furnace. At this time, if the firing temperature is less than 1350 ℃ ceramic crystals will not be formed, if the firing temperature is less than 30 hours, the crystals are not sufficiently formed and the composition of the crystals is completed 34 hours before firing for more than 34 hours productivity Since it is not good, it is baked at 1350 degreeC for 30 to 34 hours.

When the calcination is completed, the calcined calcined product is pulverized, so that the calcined calcined product can be pulverized over the first and second so as to be manufactured into nanopowders.

First pulverization is to make the fired material to about 10mm, using a hammer crusher (Hammer Crush). The hammer grinder is a general-purpose impact grinder pulverized by the impact of the swing hammer rotating at high speed and the impact of the liner, the particle size is adjusted by the screen, all the raw material is sent to the screw bend grinding chamber The fine powder ground below a predetermined particle size is made into a product through the lower screen and discharged.

The pulverized product pulverized to about 10 mm using a hammer grinder is used to have a particle size of 100 mesh to 1 nm using a jet mill or other nano powder manufacturing machine.

When the particle size of the pulverized powder exceeds 100mesh, the particle size is large, making it difficult to use as a raw material for medicines or cosmetics, and when the particle size is less than 1 nm, there is a disadvantage in that the production cost increases. Therefore, the particle size is set to 100 mesh to 1 nm. It is not limited to 1 nm.

When the pulverization is completed, the pulverized fired material is arranged in a deposition furnace to form a titanium ion thin film. The thin film deposition method is a dry deposition method, arranging the pulverized product in titanium and a deposition furnace and heating at a temperature of 300 ~ 400 ℃, when the reaction gas nitrogen, oxygen, acetylene, etc. is added to the evaporated particles of titanium Titanium ion thin film is formed by ionizing and impinging on the surface of the bioceramic powder.

At this time, the height of the deposition furnace should be more than 2m, because the powder is sucked in the vacuum process may cause mechanical problems.

In addition, since the thin film is formed only on the powder on the surface when it is deposited as it is, the computer-controlled timer is installed in the deposition furnace, the circular container is arranged inside the deposition furnace, and 3 to 10 rakes are attached thereon. Connect the plate to the computer control timer. When the connection is completed, first deposit it for 1 to 10 minutes in the stationary state, and then rotate the rake attachment plate at 5 to 10 rotations per minute for 1 minute to repeat the titanium oxide thin film for 3 to 10 times. .

Titanium-ion thin film formed as described above reactivates and normalizes the dislocation potential of human body pain to normalize the function of cells to relieve inflammation and malaise, and removes waste products to promote blood circulation by removing clogged blood in the body. In addition, it has an effect of enhancing metabolism, and when ceramics having a titanium ion thin film is used as a raw material for medicines, the skin potential changes to a normal state, thereby relieving the pain caused by the change of the cell membrane potential in a short time. Rather, it allows you to relax your muscles by allowing your blood circulation to go smoothly.

When the titanium ion thin film is formed in the same manner as above, the silver ion colloidal solution is sprayed onto the fired product on which the titanium ion thin film is formed. The silver ion colloidal solution refers to a colorless, tasteless, and odorless solution prepared by preparing pure silver (Ag 99.99%) with ultrafine particles of 0.1 to 0.005 μm and suspended in distilled water. In the present invention, purified water is added to pure silver having a purity of 99% or more. By charging and applying an electric current, colloidation and extraction are carried out with very small particles of 0.005 to 0.015 µm.

At this time, if the particle of the silver ion is less than 0.005㎛, it is difficult to manufacture, and as the particle size is larger than 0.015㎛, the antimicrobial activity is lowered, so that it is ionized into a very small particle of 0.005 ~ 0.015㎛.

Spraying the finished silver ion colloidal solution to the fired product formed with the titanium thin film, the particles are smaller than mixing the silver powder, so that the antimicrobial activity is strengthened, and the silver ions can adhere to the powder surface of the individual particles. Therefore, not only can exhibit the antimicrobial ability evenly, but also can perform the antibacterial and antifungal action to many kinds of bacteria, viruses and fungi that reduce the ability of the ceramic powder.

In addition, oxygen is contained between the silver ions to serve to supply oxygen to the skin.

The ceramic powder produced by the above method can be used safely as a raw material of cosmetics, as well as a raw material of medicines.

Hereinafter, the effects of the present invention will be described.
