In order to provide the honeycomb panel with corrosion resistance and antimicrobial properties and to pursue the nonflammability, a coating composition containing a basic binder according to the following formula 1 may be prepared and coated on the outer surface of the honeycomb panel.

In the present invention, the term " nonflammable " means resistance to fire in addition to corrosion resistance, and means a property having enhanced resistance to fire rather than flame retardancy in a general sense.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flow chart showing a procedure of a method for producing a nonflammable coating composition for a honeycomb panel of the present invention.

The method for preparing and applying the non-combustible coating composition for a honeycomb panel of the present invention may include a coating composition preparing step (S100) and a coating composition applying step (S200).

First, the coating composition preparation step (SlOO) may comprise, relative to the weight of the total coating composition, 60 to 80% by weight of the basic binder according to formula 1, 1 to 10% by weight of polyurethane, 1 to 10% by weight of colloidal silica, 10 to 10 wt%, water 5 to 15 wt%, and isopropyl alcohol 5 to 15 wt% are mixed to prepare a coating composition.

Thereby imparting nonflammable properties to the inventive nonflammable coating composition. The manufacturing process of the basic binder is well known in the above-mentioned Patent Document 1 (Korean Patent No. 10-1884308), so a detailed description thereof will be omitted. In addition, polyurethane has a urethane bond in the molecule and is a nonflammable material, which provides the function of maximizing the nonflammability of the coating composition. In addition, colloidal silica is a binder having high heat resistance and abrasion resistance because amorphous silica (SiO ₂ ) fine particles having a negative (-) charge of 1 to 100 nm in size are colloidal in water, (Cardanol) imparts antibacterial properties to coating compositions with natural alkylphenol compounds, and water and isopropyl alcohol serve as solvents in the coating composition preparation step (S100).

[Chemical Formula 1]

Next, the coating composition applying step (S200) is a step of applying the coating composition prepared through the coating composition preparation step (S100) to the prepared honeycomb panel, wherein the coating method is a spraying method using a commercially available spray Or the coating composition can be applied by using a brush, and there is no limitation in the method.

By applying the coating composition thus prepared to a honeycomb panel, the honeycomb panel is nonflammable and stable at high temperature and fire, and has antibacterial and abrasion resistance.

Further, after the above-described coating composition preparation step (S100), a composite coating composition is prepared by mixing 5 to 15% by weight of an additional binder according to the following formula (2) with 85 to 95% by weight of the coating composition prepared by the above- The composition preparation step can be carried out, wherein the composite coating composition can have improved adhesion strength, abrasion resistance and solidification ability over the coating composition due to the addition of additional binders.

FIG. 2 is a flow chart showing a method for producing an additional binder according to the present invention, and the process for preparing an additional binder according to the following formula 2 may include a polymer preparation step (S110) and an additional binder completion step (S111) .

First, in the polymer preparation step (S110), 60 to 90% by weight of dicyclopentadiene and 10 to 40% by weight of an olefin monomer are mixed with respect to the total weight of the polymer, followed by heating at 250 to 350 ° C to prepare a polymer , For 1 to 3 hours. Here, when the polymer is produced at a temperature lower than the above temperature range (S110), activation of polymerization initiation of the polymer is difficult and the yield may be low. When the polymer is prepared at a temperature higher than the above temperature range (S110) The decomposition of dienes and olefinic monomers may occur. Therefore, it is preferable to proceed to the polymer preparation step (S110) without deviating from the above temperature range.

At this time, dicyclopentadiene, which is one kind of petroleum resin, has high reactivity due to the presence of a double bond in the structure as an active ingredient in the process of producing an additional binder, so that the polymerization reaction with the olefinic monomer can proceed easily . In addition, as the olefin monomer, propylene, ethylene, 1-hexene and the like can be used, and the unit structure is to be a weight.

Finally, the additional binder finishing step (S111) is a step of mixing 85 to 99% by weight of the polymer and 1 to 15% by weight of the hydrogenation catalyst with respect to the total weight of the additional binder, and then heating the mixture at 200 to 300 DEG C to complete an additional binder , Preferably under a pressure of 75 to 85 bar for 80 to 100 minutes. At this time, when the additional binder finishing step (S111) is performed at a temperature lower than the temperature range, the reaction does not sufficiently produce an additional binder. When the additional binder finishing step (S111) is performed at a temperature higher than the above temperature range, Can be destroyed. Therefore, it is preferable to proceed to the additional binder completion step (S111) without deviating from the temperature range. In addition, Pd (OAc) 2 / n-Bu4NBr, which is a palladium-based hydrogenation catalyst, can be used as the hydrogenation catalyst at this stage. By adding hydrogen to the weight, a double structure is made into a single structure to complete an additional binder There is no limit to the type of hydrogen that can be made into a single structure by adding hydrogen to the weight.

By adding 5 to 15% by weight of the additional binder prepared in the above process to the coating composition to produce a composite coating composition, the adhesive strength, heat resistance and chemical resistance of the coating composition are improved, and thus, even under external environmental conditions such as light, heat and ultraviolet rays It can be stable.

Since the honeycomb panel is usually used as an interior and exterior coating agent, it is required to prevent the spread of fire when a fire occurs. After the coating composition preparation step (S100), 5 to 15% by weight of the coating composition and magnesium oxide The addition of the step of preparing a flame retardant coating composition for preparing a flame retardant coating composition by mixing 5 to 15% by weight of the flame retardant agent further improves the resistance to high temperature and can more effectively prevent the spread of fire.

3 is a flow chart showing a process for producing the flame retardant and the flame-retardant auxiliary of the present invention.

The method for producing such a flame retardant may include a first solution preparing step (S120), a second solution preparing step (S121), and a flame retardant finishing step (S122).

First, the first solution preparation step (S120) is a process of preparing a first solution by mixing 50 to 80% by weight of water and 20 to 50% by weight of magnesium oxide with respect to the total weight of the first solution.

Here, magnesium oxide is a substance having flame retardancy, and magnesium oxide reacts with water to form magnesium hydroxide. (MgO + H ₂ O → Mg (OH) ₂ ) The magnesium hydroxide contained in the flame retardant material generates heat when the hydroxyl group (-OH) of the magnesium hydroxide reacts with water to generate a flame retardant effect .

Next, the second solution preparation step (S121) comprises 60 to 90% by weight of the first solution, 1 to 20% by weight of urea, 1 to 20% by weight of cyanuric acid and 0.1 to 5% by weight of hydrogen peroxide, And mixing the solution to prepare a second solution.

At this time, Urea and cyanuric acid act as a flame retardant auxiliary agent. Particularly, when urea is combined with magnesium oxide, the magnesium hydroxide complex is precipitated as a magnesium hydroxide composite, and the magnesium hydroxide complex becomes an effective ingredient of the flame retardant substance. In addition, cyanuric acid helps urea to react with magnesium hydroxide to form magnesium hydroxide complex, and hydrogen peroxide accelerates hydration reaction (MgO + H ₂ O → Mg (OH) ₂ ) of magnesium oxide described above.

Finally, the step of completing the flame retardant (S122) is a process of filtering the second solution, washing and drying the residue, and then obtaining a flame retardant to complete the flame retardant.

During this process, the second solution may be stirred at 80-120 占 폚 before filtration of the second solution, in order to promote the reaction that produces flame retardant material from the magnesium oxide. In addition, if it is cooled slowly after stirring, magnesium oxide coagulates to deteriorate the flame retardant function, so it is preferable to perform rapid cooling after the stirring process.

By preparing the flame retardant coating composition by incorporating the flame retardant thus prepared in the coating composition, the flame retardancy of the flame retardant can be synergized with the incombustibility of the existing coating composition, and the resistance to high temperature can be improved.

The honeycomb panel is used as interior and exterior paneling of buildings, cargo panels such as small ships and high-speed railways, and it is required to have a thermal insulation effect that can keep internal temperature by shutting off heat flow without being greatly affected by changes in climate and outside temperature. In order to realize such adiabatic effect, the insulating coating composition may be prepared by mixing 5 to 15% by weight of an insulating material containing silica and ceramic fibers with 85 to 95% by weight of a coating composition so as to realize a honeycomb panel .

4 is a flowchart showing a process for producing the heat insulating and functional additive of the present invention.

The method for producing such an adiabatic agent may include a step of preparing an adiabatic agent (S140 (a), an adiabatic agent (S140), an adiabatic agent ). In this case, ceramic fibers can be used as feldspar and muscovite, and as a main material of the insulating material, silica serves to block the heat transmitted from the outside to the ceramic fiber, and titania (TiO ₂ ) Silica and titania are coated on the ceramic fiber to produce an adiabatic material.

At this time, silica which is an effective component of the heat insulating material can be manufactured including the first mixed solution preparing step, the second mixed solution preparing step, and the silica finishing step.

First, the first mixed solution is prepared by mixing 1 to 15% by weight of mercaptopropyltrimethoxysilane and 85 to 99% by weight of water with respect to the weight of the entire first mixed solution. Here, since mercaptopropyl-triethoxysilane is a main material of silica, the larger the amount thereof is, the larger the silica particle size to be produced tends to be. Therefore, in order to be mixed in a homogeneous size in the coating composition afterwards, Propyltrimethoxysilane should be added within the range of the mixed amount.

Next, the second mixed solution is prepared by mixing 95 to 99% by weight of the first mixed solution and 1 to 5% by weight of the ammonia water with respect to the total weight of the second mixed solution. At this time, the ammonia water serves as a hydrogenation catalyst and accelerates the reaction rate of the silica production process, thereby helping to make the silica particles uniform in size.

Finally, in the silica finishing step, the second mixed solution is washed and then dried to complete the silica. Preferably, ethanol is used for washing and drying is performed at 60 to 90 ° C. The silica thus produced becomes an effective component of the above-described step S140 of producing an adiabatic agent.

Honeycomb panels require corrosion resistance that does not oxidize and corrode even when exposed to external air pollutants and acid rain, as well as adiabatic effects. Therefore, after the step of preparing the above-mentioned heat-insulating coating composition, a step of preparing a functional coating composition comprising mixing 90 to 99% by weight of the heat-insulating coating composition with 1 to 10% by weight of a functional additive comprising the modified zeolite and the epoxy resin as an active ingredient, By applying to the comb panel, oxidation and corrosion of the honeycomb panel can be prevented.

The method for producing such a functional additive may include an intermediate preparation step (S150) and a functional addition preparation step (S151).

First, the intermediate material preparation step (S150) is a process for preparing an intermediate material by mixing 30 to 50% by weight of modified zeolite, 25 to 45% by weight of an epoxy resin and 15 to 35% by weight of a diluent, To 100 minutes with stirring. The epoxy resin may be 1,4-butanediol diglycidyl ether, 1,6-hexanediol diglycidyl ether, or the like. May be used. It is a chemical substance having two or more epoxy functional groups in the molecule, which imparts adhesiveness and provides chemical resistance and flexibility. If the base material of the functional additive agent is not limited, the diluent is not limited to epoxy resin It acts to improve the heat resistance and adhesion while at the same time making the viscosity low. Glycerol diglycidyl ether can be used. In addition, the modified zeolite provides the function of oxidation and corrosion prevention, and the manufacturing method will be explained through the modified zeolite manufacturing method which will be described later.

Next, the functional addition preparation step (S151) is performed by mixing 65 to 85% by weight of the intermediate material, 5 to 25% by weight of the curing agent, 1 to 10% by weight of the accelerator, and 5 to 20% by weight of the filler, This is the process of completing the functional additive. Here, the filler plays a role of preventing corrosion, and mica and talc can be used as fillers, and the curing agent can be used as a curing agent because the modified aliphatic amines can be used as a curing agent and cured at a low temperature. In addition, the accelerator (Dimethylbenzylamine) can be used and serves to accelerate the hardening of the functional additive.

By adding the functional additive prepared by the above method after the step of preparing the heat insulating coating composition, the oxidation and corrosion prevention effect of the honeycomb panel can be obtained, and the chemical resistance and high flowability can be improved. Here, the modified zeolite, which is an effective component of the functional additive, can be prepared including a mixed 1 solution preparing step, a mixed 2 solution preparing step, and a modified zeolite finishing step.

Preferably, the mixing 1 solution is prepared by mixing 1-20 wt% of zeolite and 80-99 wt% of water with respect to the total weight of the mixed solution 1, and stirring the solution for 10 to 60 minutes .

Since the zeolite has excellent ion exchange ability, zinc phosphate, which will be described later, can be synthesized well on the surface of the zeolite, and thus the modified zeolite can exhibit the performance performance by chemical action.

Next, in the step of preparing the mixed 2 solution, a mixture 2 solution is prepared by mixing 70 to 90 wt% of the mixed 1 solution, 1 to 15 wt% of zinc nitrate, and 1 to 15 wt% of the phosphoric acid solution, Phosphoric acid solution.

This process is a preparation process for modifying the surface of the zeolite. As a result of the mixing of the reactants, the zinc salt of zinc nitrate and the phosphate of the phosphoric acid solution are coated on the surface of the zeolite, wherein the coating thickness of the zinc salt and phosphate is 10 to 30 nm.

Finally, the step of completing the modified zeolite is a process of completing the surface modification of the zeolite by drying the mixed solution 2 at 400 to 600 ° C and then pulverizing the solution to complete the modified zeolite. At this time, it is preferable to carry out the high-temperature drying process for 10 to 60 minutes and proceed to completely dry the moisture of the reactants used for preparing the modified zeolite. In addition, the size of the modified zeolite is in the range of 100 to 200 탆, so that the addition of the functional coating composition does not impair the performance and quality of the coating.

Through the above process, modified zeolite improved in corrosion resistance and anti-rusting ability than conventional zeolite can be obtained. The modified zeolite thus prepared is used in a functional additive manufacturing process to improve the corrosion resistance and anticorrosiveness of the functional coating composition.

FIG. 5 is a table showing the results of an experiment for a nonflammable coating composition for a honeycomb panel of the present invention.

The coating composition prepared through the above process is coated on the surface of the honeycomb panel to form a coating film. The coating film is excellent in resistance to high temperature and fire, and can block the heat flow even when the outside temperature changes .
