Looking at the reaction process for the organic-inorganic nano-hybrid binder, 40.00 wt% of nano silica sol (HS-30) was added to the reactor, and while stirring at medium speed, an alkyl silane coupling additive (γ-methacroxypropylmethoxy silane) was added in a separate mixing tank. ), 10.00 wt% of Silane (A-187) and 0.20 wt% of Acetic Acid (60%) were added to the reactor by dropping for 30 minutes.

More specifically, the pH of the mixture may be changed by adding Acetic Acid as an acidic substance, and thus the dispersibility of the organic-inorganic nano-hybrid binder including hydrophobic silica may be improved.

On the other hand, the hydrolysis and condensation reaction proceeds for 3 to 4 hours including 30 minutes of performing the dropping addition at a preset temperature (30 to 60°C) by adding Silane (A-187) to the nano silica sol. So that a siloxane bond (-Si-O-Si-) can be formed.

Thereafter, 30.00 wt% of a precursor binder and 9.80 wt% of H ₂ O (water) are slowly added to the reactor.

Thereafter, after reaction at 60° C. for 6 hours, 5.00% by weight of ethanol and 5.00% by weight of H ₂ O (water) were added to the reactor, followed by dilution.

According to the completion of the reaction (Fire out), by obtaining an organic/inorganic nano-hybrid binder corresponding to a particle size of 10-20 nm, a solid content of 36±1%, and a viscosity of 100 cps (25°C), the general water-soluble emulsion-type particle size of 100 It can provide about 10 times the radon blocking effect compared to ~1,000nm (0.1 ~ 1.0㎛).

On the other hand, the blending components of the precursor binder constituting the organic-inorganic nano-hybrid binder may be as shown in Table 2 below. That is, the precursor binder (Precursor) used in the present invention may have a low molecular weight as an unreactive material prior to the manufacture of a polymer material.

division ingredient Weight (% by weight) a H ₂ O (water) 40.90 b Triton X-405 2.00 c SM 2.00 d MMA 20.00 e 2HEMA 3.00 f 2HEA 20.00 g MAA 0.60 h APS/H ₂ O 1.0/5.0 i SBS/H ₂ O 0.5/5.0

Looking at the reaction process for the precursor binder, 40.90% by weight of H ₂ O (water) and Triton X-405 (Octylphenol ethoxylate Nonion surfactant, emulsifier) were added to the reactor, and the SM (mixed in the mixing tank) was heated to 70°C. Styrene Monomer, chemical resistant hard monomer) 2.00 wt%, MMA{Methyl Methacrylate Monomer, no yellowing hard monomer} 20.00 wt%, 2HEMA{2-Hydroxy ethyl methacrylate Monomer, functional monomer} 3.00 wt%, 2HEA(2-HydroxyEthylAcrylate) APS {Ammonium persulfate (ammonium persulfate), oxidation initiator}/H ₂ O 6 wt% (APS 1.0 wt%, H), which is a mixture solution of 20.00 wt%, MAA (methacrylic acid) 0.60 wt. ₂ O 5.0 wt%) and SBS {sodium bisulfite (sodium hydrogen sulfite), a reduction initiator}/H ₂ O 5.5 wt% (SBS 0.5 wt%, H ₂ O 5.0 wt%) was added dropping for about 3.5 hours, but APS/ H ₂ O is added and the first SBS / H ₂ O is preferably added after 30 minutes.

Here, when the ultra-fine porous zeolite composite powder is less than 5 parts by weight, the moisture vapor adsorption power is significantly decreased, and when the amount is more than 10 parts by weight, the coating film cracks may occur, and thus paint workability may be significantly deteriorated.

Ultra-fine porous zeolite composite powder is a synthetic zeolite capable of passing only molecules having a preset size with Zeolite Molecular sieves, and is used for separation of gas mixtures, and the zeolite used for this is used for pore size: 4Å (angstrom ), surface area: 800㎡/g, chemical composition: Me+x[ALO2-]x[SiO2]x]yH2O, particle size: 6~9㎛, zeolite-white carbon according to the method described later It can be used by forming a composite.

In the present invention, the term "zeolite" includes a material containing a silicon (Si) atom and an aluminum (Al) atom in its crystal lattice structure, as well as a material containing a substitution element for silicon and aluminum.

In general, when only the above-described zeolite is used as a vapor adsorption function, there is a problem that the water vapor adsorption function is deteriorated when the atmospheric pressure is increased.Therefore, a zeolite-white coal complex is formed and used by inserting white coal, which has little effect on the atmospheric pressure, into the pores of the zeolite. It is desirable to do.

To this end, activated carbon is powdered and can be used to form a zeolite-white carbon composite by forming a thin film by plasma vapor deposition on zeolite at a heat treatment temperature, mainly forming a film on the pore area, and ultra-fine porous zeolite composite powder. It is preferable to form a film of 20 to 30 parts by weight of white coal powder based on 100 parts by weight of the zeolite.

Accordingly, by forming a film of white coal powder in the pores of the zeolite, it is possible to provide an effect of preventing penetration of the organic-inorganic nano-hybrid binder into the pores and adding the function of moisture adsorption of white coal to the original function of the zeolite.

3) The ZSM-5 zeolite composite can provide excellent water vapor and radon adsorption power by adding a third weight ratio (5 to 10 parts by weight) on the "environmentally friendly inorganic coating composition having moisture absorption and desorption".

More specifically, the ZSM-5 zeolite used in the ZSM-5 zeolite composite of the present invention includes 3A, 4A, 5A, L-type, X-type, Y-type, T-type, and It is a ZSM-5 type, and the form is at least one zeolite selected from the group consisting of powder, pellet, bead, and custom form.

The ZSM-5 zeolite composite of the present invention is used to prepare a clay-based ceramic-ZSM-5 zeolite composite, and for this purpose, the clay-based ceramic is pulverized into 450 to 570 mesh, washed several times with distilled water, and then at 100°C for 24 hours. During drying, it goes through a pretreatment process to completely remove moisture.

More specifically, the ZSM-5 zeolite composite is a clay-based ceramic-ZSM-5 zeolite composite pretreated with a clay-based ceramic and ZSM-5 zeolite in a weight ratio of 1: 10 to 15 by stirring and reacting for 24 to 27 hours, ZSM- 5 By being manufactured in a way that allows the clay-based ceramic to be absorbed through the pores of the zeolite, the clay-based ceramic powder absorbed inside the pores of the ZSM-5 zeolite can serve as an inhibitor to temporarily trap water vapor.

4) Diatomite is porous silica sand (SiO ₂ ) by adding a fourth weight ratio (5 to 10 parts by weight) on the "environmentally friendly inorganic coating composition having moisture absorption and desorption", thereby providing excellent humidity control ability. Here, if it is less than 5 parts by weight, the humidity control ability is remarkably insufficient, and if it exceeds 10 parts by weight, the paint workability is remarkably insufficient.

I can. Here, if it is less than 5 parts by weight, the humidity control ability is remarkably insufficient, and if it exceeds 10 parts by weight, the paint workability is remarkably insufficient.

The volcanic stone used for the volcanic stone particles of the present invention is an ore formed by cooling magma after a volcanic eruption, and has not only moisture absorption and moisture-proof functions due to porosity, but also deodorization and catalytic functions, and a particle size of 120.5 to 180 μm And has a far-infrared emissivity of 92 to 95% at room temperature (20 to 30°C), and a radiation energy of 3.85×10 ² W/m ² .

In the present invention, the volcanic stone particles may be volcanic stone particles encoded with cellulose nanofibers as another example.

More specifically, in order to produce volcanic stone particles coated with cellulose nanofibers, cellulose nanofibers are used to convert commercial wood pulp (hardwood or softwood) into TEMPO((2,2,6,6-tetramethylpiperidin-1-yl)oxy. ), and then prepared by a simple mechanical treatment (yield 90% or more) can be used, the carboxy group content is 2.2 to 2.7 mmol / cellulose g, the fiber width is 40 to 60 nm, the fiber length is 20 to 40 By using μm, not only provides insulation performance due to the low thermal conductivity (0.0029W/mK) of cellulose nanofibers, but also provides strength when the paint is dried, and the porous volcanic stone particles are coated in a mesh type. It can provide excellent moisture absorption and desorption effect primarily from the outside.

In other words, it can be generated by coating the surface of volcanic stone particles in a mesh type using PLA (PolyLactic Acid) resin for cellulose nanofibers. For this purpose, "Eco-friendly inorganic coating composition with moisture absorption and desorption function" It is recommended to use volcanic stone particles coated with cellulose nanofibers consisting of 13 to 28 parts by weight of cellulose nanofibers and 3.2 to 4.5 parts by weight of PLA resin based on 100 parts by weight of volcanic stone particles in the corresponding fifth weight ratio (5 to 10 parts by weight). desirable.

Here, when the cellulose nanofiber is less than 3.2 parts by weight, cracks occur after the application of the moisture-proof eco-friendly inorganic coating composition, and when the cellulose nanofiber exceeds 4.5 parts by weight, the adhesion problem when applying the eco-friendly inorganic coating composition with moisture-proof function Can occur.

In addition, when the PLA resin is less than 3.2 parts by weight, the mesh structure can be easily decomposed through cracks between the volcanic stone particles of the eco-friendly inorganic coating composition having moisture-proof function and the cellulose nanofibers, and when the PLA resin exceeds 4.5 parts by weight, the moisture-proof function is provided. Absorption and moisture-proof function may be impaired after application of the eco-friendly inorganic coating composition having.

The volcanic stone particles coated with these cellulose nanofibers were coated with a honeycomb-structured mesh type to perform surface treatment (E1), compared to those using only volcanic stone particles (E2), the moisture of those using only volcanic stone particles. The volcanic stone particles coated with cellulose nanofibers, as shown in FIG. 2, not only improve water absorption by more than 20%, but also the tensile strength of the volcanic stone particles, which are easily decomposed due to the porosity, as shown in FIGS. And it was found that both the breaking strength and the rupture strength were improved.

At this time, for tensile strength, Hounsfield's tensile strength meter is used according to TAPPI T 404 om-87, and MIT type according to TAPPI T 511 om-83 is used for the tensile strength. When measuring the breaking strength, the tensile load was set to 0.4 kg, the stiffness of the Clark type was used according to TAPPI T 451 cm-84, and the rupture strength of the Mullen low pressure tester was used according to TAPPI T 403 om-85.

In addition, the volcanic stone particles coated with cellulose nanofibers have high specific surface area, specific strength, and low density of cellulose nanofibers, so they not only exhibit excellent physical properties corresponding to the reinforcing function to paints, but also have excellent thermal and mechanical properties even in a very small amount. A composite can be obtained, and environmentally friendly and lightweight properties can be provided.

On the other hand, PLA is a natural plant-based raw material made mainly of corn starch, and does not contain synthetic resins (PC, ABS, etc.) and is 100% decomposed under natural conditions. In addition, it can prevent the generation of harmful substances such as dioxin and other environmental pollution.
