BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a functional indoor building finishing composition having hygroscopicity and moisture-proof property according to preferred embodiments of the present invention and a method of manufacturing the same will be described in detail with reference to the accompanying drawings.

The present invention provides a functional indoor building finish material having hygroscopicity and moisture-proof property (also referred to as 'elastic coat' in the case where it is applied to a wall or a ceiling or used for wallpaper). The functional interior finish composition comprises from 10 to 20 parts by weight of water, from 10 to 30 parts by weight of a binder, from 20 to 40 parts by weight of a first inorganic pigment and from 10 to 25 parts by weight of a second inorganic pigment. Hereinafter, each component will be described in detail.

First, the functional interior finish composition according to one embodiment of the present invention comprises 10 to 20 parts by weight of water.

And 10 to 30 parts by weight of an organic or inorganic binder. As the binder, a polymer synthesis emulsion selected from the group consisting of an acrylic polymer, a silicone polymer, a urethane polymer, and an acrylic-silicone copolymer polymer may be used. When the binder is used in an amount less than 10 parts by weight, when the composition of the present invention is used as a wall-wicking material, the adhesive strength, water resistance and durability are lowered. When the binder is used in an amount exceeding 30 parts by weight, The functions of the pigment and the second inorganic pigment deteriorate and the dew condensation preventing performance is deteriorated.

The functional interior finish composition according to one embodiment of the present invention includes 20 to 40 parts by weight of the first inorganic pigment. Wherein the first inorganic pigment comprises 15 to 25 parts by weight of a porous particulate material, 20 to 30 parts by weight of soda feldspar, 20 to 30 parts by weight of refractory clay, 15 to 25 parts by weight of tourmaline, 5 to 15 parts by weight of tourmaline, To 15 parts by weight.

First, the first inorganic pigment may be at least one selected from the group consisting of diatomaceous earth, clay, loess, tea clay, alopen, peat, silicon dioxide, calcium oxide, calcium hydroxide, calcium carbonate, char, activated carbon, bentonite, vermiculite, sepiolite, zeolite, And 15 to 25 parts by weight of a porous particulate material selected from the group consisting of cement.

The porous particles are prepared by processing the above components into fine particles to increase the surface area of the porous particles.

The diatomaceous earth is a main constituent of natural mineral clay, and is composed of porous fine particles, and has excellent function of reducing formaldehyde which is a cause of sick house syndrome. Especially, in Japan, it has been certified as a building material that reduces pollution caused by Volatile Organic Compounds (VOCs) in indoor air.

The clay, loess, and tea clay are porous fine particles, which are natural minerals having excellent humidity control. The above-mentioned sepiolite and zeolite have been found to be superior to simple diatomaceous earth walls and other products as a result of the research institute's experiments.

 Allopen is a major component of natural mineral clay of volcanic ash, and it is known that it has the advantage of being excellent in the function of reducing formaldehyde, which is a cause of sick house syndrome, composed of porous fine particles.

And allopen is porous fine particles, which is made of volcanic ash, which has excellent humidity control function, and is known to have absorption and desorptive ability of 4 to 5 times of diatomaceous earth and 15 times of humidity wall paper. Alopen also absorbs moisture when the humidity is high in the room and lowers the humidity when the humidity is low. Therefore, it is possible to maintain the optimum humidity (50% to 60%) of the living space, to prevent the allergy and the atopic disease by suppressing the propagation of the germs. On the other hand, the results of experiments conducted by Korean research institutes have shown that they have an effect on alkaline odors such as ammonia and trimethylamine, which are major components of odor, and acid odor components such as hydrogen sulfide and methylmercaptan. Odor removal and mitigation effects have been demonstrated to be superior to diatomite walls and other products.

Calcium carbonate, calcium carbonate, charcoal, activated carbon, bentonite, vermiculite, pozzolan, and the like can be mixed with an organic binder or an inorganic binder.

Due to its hydration, microcement constitutes hard strength by mixing with water and can be formed into various shapes by hydration. Micro cement is a particulate cement which is developed to be suitable for inorganic ground fillers and various repair or reinforcement materials. It is widely used as ground filler and repair reinforcing material, which require uniform grain size as well as roughness, high strength and high durability, .

Since the microcement is a fine powder, the microcement is rapidly activated and its early strength is excellent. Since a compact matrix is formed, the microcement has an excellent strength development rate, a good particle size and a small maximum particle size, And has excellent durability.

When the porous particles are used in an amount less than 15 parts by weight, the specific functional content per unit area of the coating film is lowered, and the water resistance and weather resistance, which are the physical properties of the first inorganic pigment, are lowered. On the other hand, if the amount of the component is more than 25 parts by weight, the durability of the indoor building finish material tends to be low, and the function of preventing condensation may be deteriorated.

And the first inorganic pigment comprises 20 to 30 parts by weight of soda feldspar. If it is used in an amount less than 20 parts by weight of the total weight of the soda feldspar, the stain resistance and the adhesion strength are lowered. When the amount is more than 30 parts by weight, the interior finish of the building may not be stained.

The first inorganic pigment includes 20 to 30 parts by weight of refractory clay. This is a clay having a refractory component for improving the flame retardant performance unlike the above-mentioned car clay. When the refractory clay is used in an amount less than 20 parts by weight, the fire resistance is deteriorated. When the refractory clay is used in an amount exceeding 30 parts by weight, stain resistance of the indoor building finishing material is deteriorated.

Also, the first inorganic pigment has 15 to 25 parts by weight of stearic acid. The stover serves to form a constant thickness even when the composition is used as a wall trimmer or the like for a small number of firing operations. If the amount of the stones used is less than 15 parts by weight, the optimum coating thickness of the indoor building finishing material can not be exhibited. If the amount of the stones is more than 25 parts by weight, durability and water resistance of the indoor building finishing material deteriorate.

The first inorganic pigment comprises 5 to 15 parts by weight of tourmaline and 5 to 15 parts by weight of talc. When the amounts of tourmaline and black talc used are less than 5 parts by weight, the dew condensation preventing performance among the physical characteristics of the indoor building finishing material is lowered. If the amount is more than 15 parts by weight, there arises a problem that the stain resistance of the indoor building finish material deteriorates.

Also, the functional interior finish composition according to one embodiment of the present invention includes 10 to 25 parts by weight of the second inorganic pigment. The second inorganic pigment includes a porous particulate and refractory clay.

Specifically, the porous particles may be selected from the group consisting of diatomaceous earth, clay, loess, tea clay, alopen, peat, silicon dioxide, calcium oxide, calcium hydroxide, calcium carbonate, char, activated carbon, bentonite, vermiculite, sepiolite, zeolite, And macrocement, and 70 to 80 parts by weight are used.

If the amount of the porous polymeric material used is less than 70 parts by weight, the performance characteristics of the moisture-proof and moisture-proofing performance of the present invention are deteriorated. If the amount is more than 80 parts by weight, the shrinkage force of the indoor building finishing material is increased, .

And the second inorganic pigment of the present invention comprises 20 to 30 parts by weight of refractory clay. If the amount of the refractory clay is less than 20 parts by weight, the fire resistance is deteriorated. If the amount is more than 30 parts by weight, the stain resistance of the indoor building finish material is deteriorated.

In the present invention, the two kinds of inorganic pigments are used separately.

The first inorganic pigment is a composition in which the composition ratio of the porous particulate material is small and the mixing ratio of other minerals is high. The basic physical properties (stain resistance, adhesion, water resistance, weather resistance, And functionality (moisture and moisture).

On the other hand, the second inorganic pigment is intended to maximize functionality, which is a characteristic of moisture absorption and moisture-proofing and performance of the present technology, by increasing the blending ratio of the porous particulate material.

In order to increase the viscosity of the above-mentioned functional indoor building finish composition, 0.1 to 0.8 parts by weight of a thickener used in general wax and the like and 2 to 3.0 parts by weight of an additive may be further used.

The thickener is preferably an alkaline thickener containing a cellulose derivative and a polyacrylic acid polymer, and has a chisel index value of 1 or less.

Examples of the additives include a dispersing agent, a cryoprotectant, a defoaming agent, a pH adjusting agent, and the like. Specifically, as the dispersing agent, at least one material selected from the group consisting of a naphthalenesulfonate-formalin condensate, a melamine sulfonate-formalin condensate, a polycarboxylic acid compound, a polycarboxylic acid ether, an aromatic aminosulfonic acid polymer and a metal salt of ligninsulfonic acid may be used Propylene glycol and ethylene glycol may be used as the anti-freezing agent. The antifoaming agent may be mineral oil type, silicone type or other antifoaming agent. The pH adjusting agent may be 2-amino-2-methyl-1-propanol.

The present invention also provides a method for producing a functional indoor building finishing composition having hygroscopicity and moisture resistance. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flowchart illustrating a method for manufacturing a functional interior finish material composition having hygroscopicity and moisture resistance according to an embodiment of the present invention. FIG.

Referring to FIG. 1, a method for preparing a functional interior finish material composition according to the present invention comprises the steps of preparing a first inorganic pigment (S100), preparing a second inorganic pigment (S200) 10 to 30 parts by weight of the binder, 20 to 40 parts by weight of the first inorganic pigment, and 10 to 25 parts by weight of the second inorganic pigment (S300).

Here, the first inorganic pigment is prepared by the following method. 2 is a flowchart illustrating a method of manufacturing a first inorganic pigment used in a functional interior finish material composition having hygroscopicity and moisture resistance according to an embodiment of the present invention.

First, one of the group consisting of diatomaceous earth, clay, loess, tea clay, alopen, peat, silicon dioxide, calcium oxide, calcium hydroxide, calcium carbonate, charcoal, activated carbon, bentonite, vermiculite, sepiolite, zeolite, pozzolan and macrocement 15 to 25 parts by weight of tourmaline, 20 to 30 parts by weight of feldspar, 20 to 30 parts by weight of refractory clay, 15 to 25 parts by weight of tourmaline, 5 to 15 parts by weight of tourmaline, And 5 to 15 parts by weight of talc are mixed to obtain a mixture (S110).

 Subsequently, water is added to the mixture and kneaded to obtain a kneaded product (S120).

Thereafter, the kneaded product is subjected to wet grinding to obtain a wet grinding product (S130). Specifically, the mixture is pulverized for 12 to 15 hours with a conventional ball mill composed of alumina balls and wet-milled to a diameter of 75 to 95 mu m.

When the grinding time of the ball mill is less than 12 hours, the grinding time of the ball mill is larger than the target average particle size (75 to 95 mu m), and the surface area of the porous fine particles becomes small, which causes the hygroscopic and moisture-proof function to deteriorate. On the other hand, when crushing in excess of 15 hours, the particle size of the target (95 탆) is crushed into minerals having a smaller particle size, and the porous characteristics of the fine particles are lowered, which causes the moisture absorption and moisture- As the finishing material is produced, heat is generated due to an increase in mixing and dispersion time, which causes a change in physical properties.

Subsequently, the wet pulverized product is dried to obtain a dry powder (S140).

Specifically, the powder is transferred to a high-pressure spray dryer and spray-dried to produce a dry powder such that the moisture content of the powder is about 4.5 to 5.5 wt%. If the moisture content of the powder is less than 4.5% by weight, the harmless microorganisms in the material may be deteriorated in activity and absorb moisture outside of the solid content of the binder during the production of the indoor building finish composition, thereby causing fine cracks on the surface. If the content exceeds 5.5% by weight, the porous property of the fine particles of the material is lowered, thereby deteriorating the humidity control function.

In this step, the dry powder is aged (S150). For example, the dried powder can be transferred to a silo and aged in a silo for about 24 hours.

Finally, the aged powder is molded to produce a pigment (S160). In this step, the aged dry powder is put into a dry press to produce the first inorganic pigment.

The second inorganic pigment is prepared in the following manner. The method for producing the second inorganic pigment is similar to the method for producing the first inorganic pigment except for the raw materials to be used and some process conditions. 3 is a flowchart illustrating a method for manufacturing a third inorganic pigment used in a functional interior finish material composition having hygroscopicity and moisture resistance according to an embodiment of the present invention.

Referring to FIG. 3, at first, the diatomaceous earth, clay, loess, tea clay, alopen, peat, silicon dioxide, calcium oxide, calcium hydroxide, calcium carbonate, char, activated carbon, bentonite, vermiculite, sepiolite, zeolite, 70 to 80 parts by weight of a porous particulate material selected from the group consisting of cement, and 20 to 30 parts by weight of refractory clay are mixed to obtain a mixture (S210).

 Subsequently, water is added to the mixture and kneaded to obtain a kneaded product (S220).

Then, the kneaded product is subjected to wet pulverization to obtain a wet pulverized product (S230). Specifically, the mixture is pulverized for 12 to 15 hours with a conventional ball mill composed of alumina balls and wet-milled to a diameter of 75 to 95 mu m.

When the grinding time of the ball mill is less than 12 hours, the grinding time of the ball mill is larger than the target average particle size (75 to 95 mu m), and the surface area of the porous fine particles becomes small, which causes the hygroscopic and moisture-proof function to deteriorate. On the other hand, when crushing in excess of 15 hours, the particle size of the target (95 탆) is crushed into minerals having a smaller particle size, and the porous characteristics of the fine particles are lowered, which causes the moisture absorption and moisture- As the finishing material is produced, heat is generated due to an increase in mixing and dispersion time, which causes a change in physical properties.

Subsequently, the wet pulverized product is dried to obtain a dry powder (S240).

Specifically, the powder is transferred to a high-pressure spray dryer and spray-dried to produce a dry powder such that the moisture of the powder is about 5.5 to 6.5 wt%. If the moisture content of the powder is less than 5.5% by weight, harmless microorganisms in the material may be deteriorated in activity and absorb moisture outside the solid content of the binder during the production of the indoor building finish composition, thereby causing fine cracks on the surface. If the content exceeds 6.5% by weight, the porous property of the fine particles of the material is lowered, thereby deteriorating the humidity control function.

In the dipping step, the drying powder is aged (S250). For example, the dried powder can be transferred to a silo and aged in a silo for about 24 hours.

Finally, the aged powder is molded to produce a pigment (S260). In this step, the aged dry powder is put into a dry press to produce the first inorganic pigment.

Hereinafter, the present invention will be described more specifically with reference to specific examples. However, the following examples and experiments are illustrative and not to be construed as limiting the scope of the present invention.
