In general, paint is a generic term for a fluid substance that paints the surface of a solid material such as paint or enamel to form a solid film to protect and beautify the surface of the object. It is good to cure dry quickly.

In 2500 years ago, in Egypt, paints using a solid film made by dry oil as a colorant (a major element of film formation) were used.In 1760, oiliness varnish, linoleum, etc. was used to form a solid film quickly when the oil was heated beforehand. It was produced domestically in Europe.

Despite the radical development of modern industry in the twentieth century, the paint industry relied on experience-based skill. After that, the development of mass production technology and synthetic dry oil technology to cope with the increasing demand of paint With the development of synthetic resins such as alkyd resins, the rapid development of the synthetic resin chemical industry has led to the production of new and superior paints.

The colorant is the main component of the coating film, which is the final purpose of the paint.It is a liquid such as linseed oil, soybean oil, tung oil, lacquer and synthetic dry oil, natural resin such as shellac and copal, processed resin such as lime resin, phenol resin, urea resin and melamine. Synthetic resins such as resins and vinyl resins, cellulose derivatives such as nitrocellulose and acetyl cellulose, rubber derivatives such as synthetic rubber, and solids such as water-soluble compounds such as polyvinyl alcohol and casein are used.

The film forming sub-elements are added in small amounts to the main elements to improve various properties such as dispersing, drying and curing of the paint, and the coating element is a solvent used to make the paint easier to paint. Do not. Alcohols such as ethanol and butyl alcohol, hydrocarbons such as naphtha and kerosene, esters such as ethyl acetate and butyl acetate, ketones such as acetone and methyl ethyl ketone, and ethers such as butyl vertical solver are used alone or in combination. .

A paint composed of the above three constituent components is called a transparent paint, and in reality, it is colored paint by adding various special pigments such as colored pigments, extender pigments, rust preventive pigments, luminescent pigments and Zion pigments according to the application.

The operation of making a coating film by painting a paint on an object is called painting, and in painting, it is necessary to treat the surface of an object first to prevent peeling or deterioration of the formed coating film. Solvents, surfactants, fillers, and the like are used to clean the surface and smooth the drawing. When painting, in order to paint with smoothness, uniformity and high efficiency, the speed of coating film formation, roughness of paint and drying method should be selected. Unlike other chemical industries, paints are closely related to electricity, machinery, and human lifestyle, and the properties of paints are diverse.

In addition to the general functions of aesthetics and protection, functional finishes can be used to maximize the resistance to physical and chemical external stimuli (heat resistance, chemical resistance), or to convert the input into high quality quality and output the high function of the conversion function (voltage, electric heating system, etc.). It is a paint containing high performance and a high function which includes not only surface modification but a surface modification, and a 3rd function by converting the property related to the surface of a coating film into a coating film by coating not only the general function of a coating but also coating as a target paint.

Recently, many functional finishes have been applied to the surface of coatings such as external functions in addition to basic functions such as paint protection and aesthetics. Among the functional finishes, inorganic coating agents are particularly suitable for the characteristics of these functions. The application range is expanding in many ways. At present, the development of paint to maximize the function is in progress through various tests, and the method of overcoming the defects of the inorganic material by introducing organic functional groups into the inorganic coating agent by using organic resin in the inorganic material.

However, the functional finishes that have been developed so far have been added to a specific function only to create a pleasant environment is a situation that is followed.

Accordingly, it is an object of the present invention to provide a functional finish capable of creating a pleasant environment by simultaneously generating anion generation, far infrared radiation, antibacterial, deodorizing, electromagnetic shielding or absorption effect.

The binder resin used in the present invention is a resin used in general paints, that is, natural resins such as shellac and copal, processed resins such as lime azine, synthetic resins such as phenol resin, urea resin, melamine resin, vinyl resin, nitrocellulose, Cellulose derivatives such as acetyl cellulose, rubber derivatives such as synthetic rubber, and water-soluble compounds such as polyvinyl alcohol and casein can be used, and it is preferable to use 15.50 to 52.42 wt%, and when the amount is less than 15.50 wt% There is a problem in that the formation of the coating film is not easy to peel off or the coating is not good, when the amount exceeds 52.42% by weight, the amount of the functional components is reduced and the functionality to be obtained in the present invention is not fully expressed.

Tourmaline, used as an anion generating stone, is a borosilicate with hexagonal columnar crystals, a natural mineral belonging to a hexagonal system, and has a nickname of tourmaline because it generates electricity itself. It is also called polar crystal because it is the only permanent mineral on earth. Tourmaline continues to generate direct current static electricity because electrons are constantly coming in from the sun, which contains both positive and negative ions, but the cations called plotons do not pass through the Earth's atmosphere and only pass negative ions in the solar wind. The negative ions are absorbed by the tourmaline's positive electrode and transported to the negative pole, and naturally anion electrons are pushed out of the negative electrode side, which then bounces along the electric field line of the positive electrode and becomes a permanent flow of electricity. It is a weak current of 0.06 mA, which is the most suitable current for the human body.

Tourmaline crystals continue to generate a weak current, so when water (H 2 O) reaches the crystal, it instantly electrolyzes the water, and also acts on water (H 2 O) contained in the air, causing electrolysis. It is a physiologic action that is continuous and safe and therefore transforms into vital water. In addition, tourmaline gemstones or powders are discharged to moisture instantaneously when they come in contact with water. At this time, water is electrolyzed and water molecules are separated into hydrogen ions (H +) and hydroxide ions (OH-), and the separated hydrogen ions are negative. It is combined with electrons emitted from the electrode and neutralized, becomes hydrogen gas, evaporates, and hydroxyl ions are combined with the surrounding water molecules to form a surface active substance called hydroxyl (H3O2) anion and covered with hardened oil. It acts to reduce the surface, that is, the acidified human body, water is weakly alkaline to the optimal pH 7.4, and when it enters the body, it boosts immune function (sterilization ability, antibacterial ability), cleanses blood, and stimulates autonomic nerves. Suppress the excitability of the sympathetic nerve.

On the other hand, Seong Kwang-seok is a semi-Granite rock that passed through the Cretaceous Period as the gneiss flowed through the Jurassic period and the granite was intruded into it. Research on the molecular activities of minerals and the phenomenon that occurs during cross-movement of cations and anions is carried out by mixing and mixing various minerals, quartz, pegmanite, fluorite, volatile minerals and porous minerals. It is a mineral that maximizes the antimicrobial activity, the anion-generating stone in the present invention is preferably used in the 2.50 to 39.48% by weight, when the amount is less than 2.50% by weight has a weak addition effect, if it exceeds 39.48% by weight Relatively, the amount of binder resin or other functional material used decreases, The castle did not have this effect or facilitate the expression of non-anion generation effect unsatisfactory issues.

In addition, it is effective to use at least one 7.50 to 44.48% by weight of at least one far-infrared emitter selected from the group consisting of ganbanite, macsumite, germanium, jade, ocher, and the like, which are already known as materials emitting far infrared rays, and the amount of use thereof is 7.50% by weight. If less than 1, the effect of addition is weak.If it exceeds 44.48% by weight, the amount of binder resin or other functional substances is relatively decreased, so that the formation of the coating film is not easy or the effect other than the far infrared radiation effect is expressed. There is an unsatisfactory problem.

Conductive polymer refers to a polymer that is electrically conductive like a metal. Generally, since polymer has an insulator rather than a conductive property, it has been widely used for the purpose of covering wires, but in 1964, Little (Little) of Stanford University This polymer, which has a conjugated backbone structure, can be a superconductor at room temperature.The polymer with full conductivity is polymeric sulfur nitride, (SN) x, discovered by Walataka in 1973, and recently polyaniline, polypyrrole, polyti Offen et al. Were developed.

In the present invention, as described above, conductive polymers such as polyaniline, polypyrrole, polythiophene, and the like, as well as conductive carbon or graphite, are added for electromagnetic wave shielding or absorption, and it is preferable to use 30.00 to 66.98% by weight. If the amount of the conductive material is less than 30.00% by weight, the addition effect is insignificant. If the amount of the conductive material is more than 66.98% by weight, the amount of the binder resin or the amount of other functional materials is relatively decreased, making the coating film difficult to form. Or there is a problem that the expression of effects other than the electromagnetic shielding or absorption effect is not satisfactory.

In addition, the antimicrobial agent and the deodorant may use both the antimicrobial agent and the deodorant commonly used in the technical field to which the present invention belongs, each of the amount of use is effective 0.01 ~ 36.98% by weight, if the amount is less than 0.01% by weight In case of exceeding 36.98% by weight, the amount of binder resin or other functional substance is decreased, so that the formation of coating film is not easy or the effect of other than antibacterial and deodorizing effect is not satisfactory. There is a problem.

In addition, in the present invention, water and a specific dispersant for dispersing a solvent and an additive capable of dissolving the binder resin, as well as other functional enhancers may be added, and solvents, dispersants, and other functional enhancers are commonly used in the art. It can be used as a screening through repeated experiments, the total amount of these are preferably used 7.50 ~ 44.48% by weight, if the amount is less than 7.50% by weight is not easy to add or dispersing easily, it is easy to manufacture as a paint If the amount exceeds 44.48% by weight, the amount of the binder resin or the amount of other functional materials is relatively decreased, so that the formation of the coating film is not easy or the functional expression is not satisfactory.

Anion generating stones, far-infrared radiators, antibacterial agents, deodorants and conductive materials used in the present invention are preferably pulverized into as small particles as possible, but from the viewpoint of ease of manufacture and economical efficiency, finely pulverized particles are used. It is effective.

The functional finishing agent of the present invention configured as described above is first dissolved in a solvent and then added at least one conductive material selected from the group consisting of a conductive polymer, conductive carbon, graphite, etc. Next, anion generating stones, antimicrobial agents and deodorants are added and again dispersed at high speed by 200 rpm or more, and then the product is prepared by filtering only the filtrate with a 400 mesh sieve.

In this case, the reason why the conductive material and other functional materials are added separately is that they are not easily dispersed due to the difference in specific gravity, and it is effective to separate and add each functional material to make the most homogeneous product. .

In addition, it is preferable to add a dispersant to facilitate the dispersion and to prevent precipitation during preparation into the finished product, and the remaining components may be mixed after mixing each functional substance with water. In this case, the dispersant may be easily inferred by those skilled in the art to which the present invention pertains, or may be used by screening through repeated experiments.
