Description

Multifunctional paint and manufacturing method thereof {Multi-Functional Paint}

The present invention is a paint which adds glycol to water and acrylic emulsion, and further adds titanium dioxide, ganbanite, monazite, silica, and flame retardant, and is a multifunctional paint that does not emit any harmful substances causing sick house syndrome and the like. It relates to a manufacturing method.

In general, various houses, apartments, office buildings, etc. are structurally stable concrete for long-term use, and synthetic resin paints, such as water-based or oil-based paints, are used as finishing materials to improve the protection and aesthetics of building structures. I use it.

The concrete structure as described above is aging gradually over a long time, the exterior finish material exposed to sunlight fades the color of the exterior material, and the concrete walls are severely corroded by soot, sulfur compounds such as vehicle exhaust gas or acid rain, Corrosion even exposes rebar, further accelerating aging. In addition, various environmental factors are harmful to the human body such as bad smell or mold on concrete floor or wall.

In order to solve this problem, faded or severely corroded exterior finishes are replaced with new boards such as stone panels and tiles, and the interior walls are repainted with synthetic resin emulsion paints.

 Measures to prevent deterioration of buildings are only temporary measures. In particular, most of the commercial paints on the market consists of organic compounds, so that the smell of the solvent, that is, environmental pollution caused by VOCs (Volatile Organic Compounds) is not only serious, but also 5 to 7 years have passed. After that, the decomposition of the organic compounds contained in the paint began to be re-coated.

On the other hand, as research on environmentally friendly buildings has been actively conducted, many research data have been published on the effect of concrete structures on the human body.

Until recently, it has been known to some extent that the toxicity of cement and internal finishing paints generated from building concrete are harmful to the human body. However, there have been no cases where such cements or paints have a great effect on the human body. .

In particular, in recent years, a new coin has been created a new house syndrome, which refers to damage to the human body due to harmful substances emitted from various paints and building materials. In other words, the skin is itchy, headache, and mental and physical instability due to the toxicity of cement released from the concrete floor and walls forming the main skeleton of the new house. In addition to chemicals such as building paints and wallpaper used as interior finishing materials, benzene, toluene, xylene and formaldehyde, which are continuously emitted from chemicals such as wooden furniture, decorative products, and curtains and carpets, are used. VOCs and heavy metals contain fatal hazards to the human body that can cause general paralysis, respiratory disease, headaches, and allergies. It implies

In order to overcome the environmental pollution problem as described above, a lot of environmentally friendly building paints have been proposed. In particular, water-based paints replaced with water rather than volatile organic compounds, ie, inorganic water-based paints mixed with simple fillers such as hard coal (CaCO3), are commercially available, and organic materials used as binders (for example, water-soluble acrylic) If this time elapses, there is a disadvantage in that it is decomposed, and in some cases, ammonia is included because of stability. In addition, inorganic ceramic paints made of sodium silicate (water glass) have a disadvantage in that they are vulnerable to water resistance.

In addition, a method of reducing solvent usage (high-solidification, high-solidification) by increasing the solid component ratio in the paint, and powder coating without using a solvent have been developed. However, the method such as aqueous or high-solidification can reduce the environmental pollutants, but it is not a fundamental solution because it has to be repainted from time to time, and in the case of powder coating requires a separate heat treatment process actually It is not applicable to concrete structures in the field.

The present invention has been made to solve the above problems, by optimizing the selection and content of environmentally friendly ingredients can not only block harmful substances and achieve the maintenance and strengthening effect of the facility, human body such as far infrared rays or negative ions It is an object of the present invention to provide a multifunctional paint capable of supplying beneficial ingredients and a method of manufacturing the same.

The paint of the present invention, in order to achieve the object as described above,

25% by weight of water, 15% by weight of acrylic emulsion, 2% by weight of glycol compound, 17% by weight of titanium dioxide, 15% by weight of ganbanite, 5% by weight of monazite, 6% by weight of silica sand, 10% by weight of silicate-based binder, 2% by weight of dispersant To provide a multifunctional paint and a method for producing the composition, which is composed of 1% by weight of a thickener, and 2% by weight of an antifoam, is a problem solving means to be achieved by the present invention.

Multifunctional paints of the present invention, the silicic acid-based Binder component penetrates into the pores of the cement to neutralize the toxicity, prevent the alkali projecting whitening of the cement, inhibit the dust generation by strengthening the surface coating to block or remove the source of harmful substances, odor Since it suppresses the occurrence, it has the advantage of keeping the room comfortable, and the far-infrared radiation intensity is strong and the amount of far-infrared radiation is emitted at room temperature, which helps in blood circulation, metabolism and cell tissue generation, and prevents skin aging. Can exert,

 By releasing large amount of negative ions, blood purification, increase resistance to infection, autonomic nervous system regulation, air purification, dust removal and sterilization, etc., the construction surface of the coating of the present invention is not burned natural It is composed of inorganic material and has the advantage of blocking harmful gas at the source.

In order to achieve the above object, the present invention is 25% by weight of water, 15% by weight of acrylic emulsion, 2% by weight of glycol-based compound, 17% by weight of titanium dioxide, 15% by weight of barbanite, 5% by weight of monazite, 6% by weight of silica sand And a multifunctional paint composed of 10% by weight of a silicic acid-based binder, 2% by weight of a dispersant, 1% by weight of a thickener, and 2% by weight of an antifoaming agent and a method of manufacturing the same.

When explaining the role and content of each component constituting the multifunctional paint of the present invention.

First, water serves as a continuous medium of the components constituting the paint of the present invention, the components are evenly mixed to realize a uniform physical properties. The content of the water is composed of 15 to 30% by weight relative to the total weight of the composition, if less than 15% by weight is too high viscosity has a disadvantage of difficult operation, if more than 30% by weight as well as the hiding power, when flowing to the wall Development or staining may occur, preferably 25% by weight.

The acrylic emulsion that serves as the binder of the present invention is used commercially mixed with an acrylic compound (2- Ethyl Hexyl Acrylate Monoma and Acryl acid), water, emulsifier (hydrophilic emulsifier),

The amount of the acrylic emulsion is used 15% by weight of the acrylic emulsion relative to the total weight of the composition, if less than 14% by weight has a problem that the water resistance is sharply reduced, on the contrary, if more than 20% by weight, the hiding power is lowered and the drying is not smooth There are disadvantages.

As the glycol compound used in the present invention, ethylene glycol, propylene glycol, polyethylene glycol, polypropylene glycol, and the like may be used, and the content thereof is 2% by weight based on the total weight of the composition. The possibility becomes high, and when it exceeds 2 weight%, drying time becomes too long.

In addition, the titanium dioxide of the present invention imparts hiding power and whiteness, and in particular, the crystal structure is more preferably rutile. Titanium dioxide uses 17% by weight based on the total weight of the composition. If it is less than 17% by weight, hiding power and whiteness are lowered. If it is more than 17% by weight, the adhesive strength of the paint is lowered, and cracks may occur.

 Elvan rock of the present invention uses 15% by weight relative to the total composition weight. If less than 15% by weight, the amount of far-infrared emission is insignificant, and the energy saving efficiency described above is inferior. And, if the content exceeds 15% by weight, not only the concealment and adhesive strength is lowered, but also cracks are easily generated, the color of the paint is dark overall, the preference is severely lowered.

 Monazite is a phosphate of cerium, lanthanum, and thorium, which emits energy at all times by these rare earth metals, while phosphates release hydroxyl radicals and superoxide ions in contact with water to perform antibacterial, sterilizing and deodorizing functions. It is a substance. In particular, the rare earth metal, fluorine, and the like, which are partially contained, have an additional feature of removing the surrounding phosphorus. Monazite is less than 5% by weight of the total composition of the negative ion release amount and accordingly has a disadvantage in reducing the sterilization effect, more than 5% by weight is not economical compared to the increase in the amount used.

The silica sand of the present invention uses 6% by weight of silica sand relative to the total weight of the composition, and below the content range, the effect of improving economics is halved, and if it exceeds the range, hiding power and adhesive strength are lowered.

Silicate based binder of the present invention uses any one compound selected from sodium silicate, potassium silicate, lithium silicate, calcium silicate, using 10% by weight relative to the total composition weight, can impart flame retardancy to the paint of the present invention It is difficult to control humidity as well as a problem that easily burns when a fire occurs under the above range. If the above range is exceeded, water resistance is lowered, and penetration into concrete or cement products prevents aging.

The dispersing agent of the present invention uses 2% by weight of the total composition, less than 2% by weight is not easy to disperse because the particles are agglomerated, difficult to work, more than 2% by weight is poor adhesion and weather resistance. The dispersant used in the present invention is particularly preferably used by mixing sodium hexametaphosphate and potassium hydroxide in a weight ratio of 5: 4 to 6.

 The thickener of the present invention mainly uses HEC (Hydroxy Ethyl Cellulose), and uses 1% by weight based on the total weight, less than the above range can be precipitated, solidified components of the high specific gravity of the paint component of the present invention. And, if the above range is exceeded, there is a problem that the gel becomes poor workability, water resistance is lowered.

In the paint of the present invention, the antifoaming agent uses paraffinic mineral oil to suppress the generation of foam, and uses 2% by weight relative to the total weight, and it is difficult to suppress the generation of foam below the above range, and it is not economical if it exceeds the above range. There are disadvantages.
