At present, pollution of the air and destruction of the natural environment have emerged as a major problem of society, that is, the development of electronic civilization and the convenience priority of the automobile culture society are progressing, not limited to the existing air pollution problem. The quality of air around human bodies has emerged as an important issue, of which atmospheric air is found to be charged with positive ions.

In addition, many toxic substances remain in the interiors of chemicals and new buildings, and these are becoming more of a concern for their relationship with cations, and such cationization is a major problem for human health. In other words, headache, dizziness, vomiting, nausea increases the discomfort, as well as oxidizing the cells of human tissue to stimulate the autonomic nerves are known to promote the aging of the body by worsening the circulation of the endocrine system, immunity, and body fluids.

On the other hand, it is known that there are many negative ions in the water-rich areas such as clear air and clear forests, ponds, reservoirs, lakes, and waterfalls, and everyone can feel pleasant and refreshing and have a great influence on the flora and fauna of the ecosystem. There is a growing indication that industrial fields that apply useful roles according to negative ions are being used in various fields, and many products are focused on actual functionality.

There are many ways to generate these anions, which are made naturally or artificially. That is, there are ions generated by ultraviolet rays, the method of ionizing the gas when ultraviolet rays pass through the gas, and the method of generating ions by collision of ions when the electric field on the earth's surface in the atmosphere is 10 Kv / cm or more, How radon, a decay substance such as uranium and torium buried in the air, diffuses through the earth's crust into the atmosphere, and when the water droplets break down into smaller droplets, the split spray itself gets positive electricity so that the surrounding air It is known that the negative ion is emitted from the corona discharge effect, the electrospinning of emitting the electron beam into the air, the method of obtaining anion effect from mineral resources such as tourmaline, and other fine particles and charcoal of clay powder.

In the present invention, the particles were pulverized tourmaline stone, which was originally a gemstone, but the anion generated by the existing high voltage is generated forcibly from stable molecules, and thus has a short life of 7 to 8 seconds, and also generates electromagnetic waves and ozone due to discharge. Hazardous substances are generated and can cause secondary contamination.

Hereinafter, the production process of the anion-emitting and far-infrared radiation inorganic ceramic coating composition according to the present invention will be described in detail with reference to the accompanying drawings.

(Example 1)

In the above formula RnSiX _4- n, X is the same or different from each other, a hydrolyzable group or a hydroxyl group, the radicals R are the same or different from each other, and represent hydrogen, an alkyl group having less than 10 carbon atoms, and n is 0, 1 or 2 One or more silanes are used.

(Example 2)

65 to 83 wt% of an inorganic binder which acts as a binder as a mineral solution hydrolyzed and condensed in the presence of at least one compound selected from alkali oxides, oxides of alkaline earth metals, alkali hydroxides and alkaline earth metals, and the binder and silicon 19 ~ 10wt% of functional fillers to prevent cracking of coatings and to adjust the viscosity between the mixtures to improve the physicochemical properties of coatings, 1 ~ 2wt% of pigments to give color, and ceramic powder to emit far infrared radiation and anion 15-5 wt% is mixed.

Functional fillers used in Examples 1 and 2 use potassium titanate, alumina, and the like, and their particle shape is needle or plate to prevent cracking of the coating film between the binders or to control the viscosity of the coating agent. When the functional filler is added in an amount of 10wt% or less with respect to the total weight part, it may cause a decrease in gloss or adhesive force, and when it is added in an amount of 19wt% or more with respect to the total weight part, the surface of the coating film becomes rough. It is preferable to add within the range of 10 to 19wt% based on the total weight by giving.

The ceramic powder added in Examples 1 and 2 is a material that emits negative ions together with far-infrared radiation, the far-infrared radiation material is quartz, monzonite, gneiss and rhyolite tuff having a far-infrared emissivity of 90% or more at room temperature 40 degrees. It uses a ceramic containing at least one selected from the group of natural minerals such as tourmaline, loess, biotite, amethyst, raw ore, bamboo charcoal, uranite, jewelry, obsidian, elvan, ore, lava, and gemstone. The anion releasing material of the ceramic powder uses one rare earth natural stone selected from strontium, vanadium, zirconium, cerium, neodymium, lanthanum, barium, rubidium, cesium and gallium, and the material already emits anions and far infrared rays. It is known.

When the ceramic powder is added in an amount of 2wt% or less based on the total weight, it is difficult to anticipate the effect of far infrared rays and anions, and when it is added in an amount of 15wt% or more based on the total weight, the state change and adhesion of the coating film may be lowered. Addition within the range of 2 to 15wt% with respect to the part has a high anion release effect, can prevent the state change of the coating film, as well as maintain strong adhesion.

Inorganic ceramic coating composition of the present invention consisting of the above components and composition ratio is applied to the surface of the metal or plastic substrate and thermally densified to form an inorganic coating film, when the inorganic ceramic coating agent in the present invention treated the substrate The distribution of anions per 1cc of air, which is refreshing to the human body in forests, waterfalls, and hot springs, was adjusted to 800-2,000 levels.

Hereinafter, the manufacturing process of Examples 1 and 2, which is an anion-emitting and far-infrared radiation inorganic ceramic coating composition according to the present invention, will be described in detail.

First, the manufacturing process of Example 1 is 40-50 wt% of a binder serving as a binder as at least one silane such as the above-described formula RnSiX ₄ -n or an oligomer derived therefrom, and powdered silicon oxide (SiO) having a particle size of 0.2-1.0 μm. ₂ ) After mixing and adding 34 ~ 24wt% of the silicon mixture mixed with 20 ~ 40wt% of water and 80 ~ 60wt% of water, put into the reactor and stir, the water and silicon molecules of the binder and silicon mixture are combined with each other by chemical reaction The binder mixture manufacturing process (1) which manufactures the binder mixture of a sol state is performed. At this time, an exothermic reaction of 40 ~ 50 ℃ appears.

When the binder mixture manufacturing process (1) is completed, tourmaline, loess, biotite, amethyst, raw ore, bamboo charcoal, royal stone, noble stone, obsidian, to increase the functionality of the coating film in the binder mixture formed by binding the binder and the silicon mixture to each other Natural minerals such as 19-10 wt% of one or more functional fillers selected from one or more natural stone materials selected from elvan, wangmyeong, lava, and gemstones, and quartz, monzonite, gneiss and rhyolite tuff with 90% or more of far-infrared emissivity at room temperature. Ceramic powder composed of far-infrared radiating material comprising at least one selected from the group and an anion emitting material which is one rare earth natural stone selected from strontium, vanadium, zirconium, cerium, neodymium, lanthanum, barium, rubidium, cesium and gallium When 5 ~ 15wt% and 2 ~ 1wt% of pigment for coloring are added to the reactor and mixed It executes the inorganic ceramic mixture prepared step (2) to produce an inorganic ceramic mixture by a response.

In order to control the viscosity and reaction rate of the solution during the process of preparing the inorganic ceramic mixture (2) it can be adjusted by adding any one selected from methanol, ethanol, isopropanol or alcohol mixture.

Then, the mixed solution made through the inorganic ceramic mixture manufacturing process (2) is placed in a homogenizer (Homogenizer) to homogenize the particles while stirring for about 30 minutes at high speed, and then passed through a filter network of about 325 ~ 400 mesh (Mesh) By performing the mixing and filtration process (3) to extract the filtered particles as a coating agent to complete the preparation of the anion release and far-infrared radiation inorganic ceramic coating composition according to the present invention.

Next will be described the manufacturing process of Example 2.

First, 47 to 33 wt% of methyltrimethoxysilane and 23 to 17 wt% of tetraethoxysilane are mixed to prepare a binder that serves as a binder, and 30 to 50 wt% of silica sol is added to the binder and mixed, followed by stirring. When the exothermic reaction occurs by a chemical reaction, and after about 1 to 2 minutes in the turbid state of the reaction to become a clear transparent liquid to perform a binder mixture manufacturing process (11) to prepare an inorganic binder mixture of the sol state.

The reason why the inorganic solution is used is that, in general, when the anionic powder is mixed with the general coating agent, the general coating agent completely encloses the anion powder, thereby reducing the amount of anion released. Therefore, since the anion powder must be an inorganic ceramic as a condition for completely releasing anions, an inorganic solution that is the same as the inorganic ceramic powder is selected and used.

In the inorganic solution binder, when methyltrimethoxysilane and tetraethoxysilane are added in the range of 47 to 33 wt% and 23 to 17 wt%, respectively, the reactivity is lowered. As the physical properties are lowered, the binder having the best physical properties can be obtained only when it is added within the above range.

In addition, when silica sol is added in the range of 30-50 wt% or less, the bonding force of silicon-oxygen-metal (Si-O-Metal) between the methyltrimethoxysilane and tetraethoxysilane is weak and peeled off at high temperature. It is preferable to mix within said range as this generate | occur | produces.

In order to control the viscosity and reaction rate of the solution during the binder mixture manufacturing process (11) it can be adjusted by adding any one selected from methanol, ethanol, isopropanol or alcohol mixture.

In order to increase the functionality of the coating film in the inorganic binder mixture formed by binding the binder and the silica sol through the inorganic binder mixture manufacturing process 11 as described above, the binder mixture 65 ~ 83wt%, tourmaline, loess, mica, amethyst, raw 19 ~ 10wt% of functional fillers made of one or more natural stone materials selected from ore, bamboo charcoal, Uiwang, noble stone, obsidian, ganban stone, ore, lava and precious stone, and quartz, monzonite, which have far-infrared emissivity of 90% or more at room temperature Far-infrared radiation including one or more selected from natural mineral groups such as gneiss and rhyolite tuff, and one rare earth selected from strontium, vanadium, zirconium, cerium, neodymium, lanthanum, barium, rubidium, cesium and gallium 15 ~ 5wt% of ceramic powder composed of anion emitting material, which is a natural stone, and 1 ~ 2wt% of pigment for coloring. When the mixture is added and mixed, an inorganic ceramic mixture manufacturing step 12 is performed in which an inorganic ceramic mixture is produced by a chemical reaction.

Next, the mixture prepared through the inorganic ceramic mixture manufacturing process 12 is placed in a homogenizer, and the particles are homogenized while stirring at a high speed for about 30 minutes, and then passed through a mesh of about 325 to 400 mesh. By performing the mixing and filtration process 13 to extract the filtered particles as a coating agent to complete the preparation of the anion release and far-infrared radiation inorganic ceramic coating composition according to the present invention.

When the inorganic ceramic coating composition is applied to the coated substrate, various inorganic components contained in the coating agent form a layered structure, thereby making the silicon-oxygen-metal bond harder to form a ceramic film, so that the substrate and the coating layer are separated from each other. The phenomenon is not generated, and when heat is applied, far infrared radiation and anion are released from the inorganic ceramic coating composition.
