Description

Eco-friendly water-based color bone tile paint composition and manufacturing method thereof {Water-based color bone tile paint composition and manufacturing method thereof}

The present invention relates to an eco-friendly water-based color von tile coating composition and a method for manufacturing the same, and more specifically, it can be used in an environmentally friendly manner, and the pigment particles can be adhered without dripping when painting / spraying on the inner or outer wall of a building Eco-friendly water-based that enables the formation of beautiful three-dimensional patterns and at the same time realizes various colors desired by the user, so that a color coating film can be formed on the inner or outer walls of a building with only one coat without separate oil paint. It relates to a color bontile paint composition and a manufacturing method thereof.

The inner or outer walls of the building are painted as one of the finishing processes. This coating film is applied in the form of spraying, so that a concavo-convex pattern is formed and a three-dimensional effect is applied. There is a method of forming a coating film by coloring oil paints of various colors, etc.

Among these, in the case of tile paint, since it does not basically have color, paint to which a separate pigment is added must be painted once more in order to express the color.

In addition, since the conventional bone tile paint contains bubbles as a water-based material and the pigment is basically a powder component that is insoluble in water, when the pigment is added to the bone tile paint, it is difficult to express color because it is not dispersed due to the physical properties of the paint itself. It was impossible. In addition, since the coating film does not stick to the inner or outer wall of the building where the paint is painted while becoming heavy due to the weight of the pigment and flows down, it is difficult to manufacture the conventional bone tile paint as a colored paint having its own color.

Therefore, conventionally, in order to paint the interior or exterior walls of a building in a color desired by the user, first spray the interior or exterior wall of the building with bone tile paint without pigment, and then paint the color of the user desired on it after the bone tile paint dries A separate painting method was used.

However, in the case of paint to be painted over this tile paint, it is an oil-based product and contains volatile organic compounds due to the nature of the mixing raw material, which is harmful to the human body and has a strong odor, and due to these characteristics, it is not easy to use it inside the building.

In addition, conventional paints have low workability, storability, and adhesion, so that the quality of the paint film does not meet the user's expectations, and the lifespan after painting is not long and maintenance is inconvenient.

1 is a flowchart showing a method for preparing an aqueous color bontile paint composition according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, embodiments of the present invention may be modified in many different forms, and the scope of the present invention is not limited to the embodiments described below.

In addition, 'include' a component throughout the specification means that other components may be further included, rather than excluding other components unless otherwise stated.

An eco-friendly water-based color bontile paint composition of one embodiment, water; Based on 100 parts by weight of water, 0.18 to 0.20 parts by weight of a first modifier; 0.36 to 0.40 parts by weight of a second modifier; 38 to 42 parts by weight of a pigment extender; 360 to 400 parts by weight of a first binder; 28 to 32 parts by weight of a second binder; and 74 to 79 parts by weight of a waterproofing agent; The pigment extender may include an extender pigment and a color pigment, and the extender pigment and color pigment may be included in a ratio of 7:3 (extender pigment:color pigment).

In the water-based color von tile coating composition of this embodiment, a mixing step of preparing a first material by mixing liquid raw materials (S10), a dispersing step of preparing a second material by adding solid raw materials to the first material and mixing them evenly (S20) ), and an adjustment step (S30) to improve the properties of the second material.

Hereinafter, in the description of the blending step (S10), the dispersing step (S20), and the adjusting step (S30), the content of each component is the amount of water used in the blending step (S10) and the water used in the adjusting step (S30). In addition, the total amount is 100 parts by weight, and the relative content thereof is shown.

First of all, the mixing step (S10) will be described. A first material is prepared by mixing a liquid first modifier and a liquid second modifier in water.

The first modifier may preferably be hydroxypropyl methylcellulose (HPMC), which is an eco-friendly material, and a product called NP40US of Hyunam Co., Ltd. may be used.

The first modifier serves as a surfactant and a thickener, and increases the viscosity of the paint composition to prevent the water-based color bontile paint composition of one embodiment from flowing down when sprayed on the wall, flowability and thixotropy during painting can act to improve.

The first modifier may be included in an amount of 0.18 to 0.20 parts by weight. If the content of the first modifier is less than 0.18 parts by weight, workability, such as flowability, and thixotropic degradation may occur, resulting in a decrease in the coloring power of the pigment extender added in the dispersing step described later. there is.

In addition, when the content of the first modifier exceeds 0.20 parts by weight, the viscosity of the paint composition is too high, so that the painted surface becomes too uneven when applied to the wall by spraying, making it impossible to provide a clean appearance or difficult to even the thickness. Problems of deterioration in workability may occur, lifting may occur during spraying, deterioration of color, and layer separation during storage of the aqueous color bontile paint composition. can happen

The second modifier may preferably be polyoxyethylene nonylphenyl ether, and a product called NP1050 may be used. The second modifier may serve as a surfactant, a dispersant, and an emulsifier in the water-based color von tile paint composition of one embodiment.

The second modifier may be included in an amount of 0.36 to 0.40 parts by weight. When the content of the second modifier is 0.36 parts by weight, pigment components of the pigment extender added in the dispersing step described below may precipitate and storage stability may deteriorate.

In addition, when the content of the two modifiers exceeds 0.40 parts by weight, the inherent color of the pigment and the strength of the coating film may be lowered, and the surface tension of the water-based color von tile paint composition may be lowered, causing a lifting phenomenon during painting. can occur

At this time, in the mixing step (S10), the first material may be prepared by further adding a first antifoaming agent, an anti-drying agent, and a first pH adjusting agent.

The first antifoaming agent may preferably be modified silicone, and a product called SN DEFOAMER399 from San Nopco may be used. The first antifoaming agent removes or evenly distributes air bubbles present in the water-based color von tile paint composition to improve the wettability of the pigment added in the dispersing step described later, so that the binder can easily wrap the pigment, and when spraying, the paint film It can serve to improve the workability during spraying while improving the quality and further improving the effect of preventing the paint composition from flowing down.

1.0 to 1.2 parts by weight of the first antifoaming agent may be included. If the content of the first antifoaming agent is less than 1.0 parts by weight, the bubble removal effect may be insignificant, and a problem in that the intrinsic color of the pigment may not be properly expressed during painting may occur, and if the content of the first antifoaming agent exceeds 1.2 parts by weight, It will only result in an increase in production cost without a significant increase in effectiveness.

The anti-drying agent may preferably be monoethylene glycol, and a product called MEG from Honam Petrochemical may be used. The anti-drying agent may serve to prevent the water-based color bontile paint composition from freezing due to a decrease in temperature in winter. In addition, the anti-drying agent may play a role of preventing the surface from drying rapidly when forming a coating film, thereby preventing the occurrence of a floating phenomenon in the coating film.

The anti-drying agent may be included in an amount of 8.5 to 9.0 parts by weight. If the content of the anti-drying agent is less than 8.5 parts by weight, the above effect may not be properly implemented, and if the content of the anti-drying agent exceeds 9.0 parts by weight, only production cost increases without a significant increase in effect.

The first pH adjusting agent may preferably be 2-amino-2-methyl-1-propanol, and a product called AMP95 from ANGUS CHEMICAL COMPANY may be used. The first pH adjusting agent may serve to maintain the pH of the aqueous color bontile paint composition at an appropriate level. At this time, the preferred pH of the aqueous color von tile paint composition may be 6.5 to 9.

The first pH adjusting agent may be included in an amount of 1.8 to 2.2 parts by weight. If the content of the first pH adjusting agent is less than 1.8 parts by weight, the water-based color von tile paint composition may be excessively acidified, resulting in gelation or deterioration of physical properties such as storage stability. Exceeding 2.2 parts by weight only causes an increase in production cost without a significant increase in effect.

Next, in the dispersing step (S20), a first binder composed of a powdery pigment extender and an organic material is added as a solid raw material to the first material and evenly dispersed to prepare a second material.

In the dispersing step (S20), when the inner or outer wall of the building is painted with the water-based color bontile paint composition of one embodiment, the water-based color bontile paint composition is well absorbed and adhered to the surface of the inner or outer wall of the building. Painting This is a process to prevent the membrane from flowing down the wall more effectively.

And, the pigment extender includes an extender pigment and a color pigment.

The extender pigment is an achromatic pigment, serves to improve the spreadability of the pigment particles and dilutes the color pigment, and can be used as a base for maintaining the formulation of the pigment extender, for example, mica, cerasite, Talc, kaolin, silicic anhydride, etc. may be used, and in one embodiment, talc may be preferably used.

The color pigment plays a role in implementing color in the water-based color bontile paint composition of one embodiment, and the water-based pigment is used. For example, titanium oxide (TiO ₂ ), Zinc oxide, lead white, etc. may be used, and in one embodiment, TiO ₂ may be used as a material having small particles, excellent whiteness, high refractive index among inorganic pigments, high hiding rate of a coating film, and excellent coloring power.

In addition, the pigment extender may be included in 38 to 42 parts by weight. If the content of the pigment extender is less than 38 parts by weight, the color of the paint film sprayed with the water-based color bontile paint composition may not be properly implemented, and it may be difficult to create a pattern desired by the user.

In addition, when the content of the pigment extender exceeds 42 parts by weight, the pigment extender is not evenly mixed in the aqueous color bontile paint composition, resulting in reduced workability, reduced adhesion of the pigment particles, and a difference in density to the paint film. A phenomenon in which the curves (pattern patterns) formed on the surface sag over time occurs, and in severe cases, the coating film may collapse.

At this time, the extender pigment and the color pigment may be preferably mixed in a ratio of 7:3 (extender pigment:color pigment) to prepare a pigment extender used in the dispersing step of an embodiment.

The saturation and brightness of the paint film are affected by the amount of color pigment added. For example, when using talc and TiO ₂ , increasing the ratio of talc requires adding more snow white to correct the saturation and brightness of the color. can occur Since color pigments are generally more expensive than extender pigments, the ratio of extender pigments and color pigments was determined through several tests as an optimal ratio to ensure the production cost of the extender and the desired color saturation and brightness. It is set at 7:3 (exterior pigment: color pigment).

In addition, when the paint composition of one embodiment intends to implement a color other than white, at least one of green, black, red, blue and yellow pigments may be used as the color pigment.

At this time, as an example, a product called PANAX GREEN 500D of Woosung Chemical may be used as the green pigment, a product called CARBON BLACK of Woosung Chemical may be used as the black pigment, and ION of Woosung Chemical may be used as the red pigment. You can use a product called OXIDE RED H50.

In addition, as an example, as the blue pigment, a product called PANA X BS 7040 or PANAX BS 770 of Woosung Chemical may be used, and as the yellow pigment, a product called PANAX YELLOW 320 of Uksung Chemical or PANAX Y810 of Benefactory Colors may be used. can be used

The first binder is methyl methacrylate, methacrylic acid, butyl methacrylate, hydroxypropyl methacrylate, ethylene glycol dimethacrylate, butylene glycol tri methacrylate, polyethylene glycol tri methacrylate, pentaacryl Diol trimethacrylate, alkyl methacrylate, cycloalkyl methacrylate, ethyl methacrylate, isobutyl methacrylate, t-butyl methacrylate, triethylpropanetri methacrylate, trimethylolpropanetri methacrylate , 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate, 4-hydroxybutyl acrylate, 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, 4-hydroxybutyl methacrylic acid One or a combination of two or more may be used from a group of copolymers of acrylic monomers such as latex.

At this time, when the glass transition temperature (Tg) of the first binder is low, the hardness, adhesion, contamination, adhesiveness, and abrasion resistance of the coating film are lowered, and the drying time is increased, and when the glass transition temperature (Tg) of the first binder is high, the coating film Since hardness, cracks, flexibility (elasticity), etc. are inferior, it is very advantageous to apply a binder with a glass transition temperature (Tg) of 0 to 30 ° C and excellent weather resistance, stain resistance and water resistance, and the hardness and Excellent durability, adhesiveness, and flexibility (stretchability).

Considering this point, the first binder may be more preferably butyl acrylate-methyl methacrylate, and a product called Aekyung Chemical's ASA1020 may be used.

The first binder is a material with improved weather resistance, quick drying and water resistance compared to the acrylic emulsion binder, and provides adhesive strength so that the powdery pigment extender can be evenly mixed into the liquid first material, and the pigment particles of the pigment extender are painted It can serve to adhere to the surface and prevent falling off, thereby extending the life of the paint film painted with the water-based color bontile paint composition of one embodiment and having excellent physical properties.

360 to 400 parts by weight of the first binder may be included. If the content of the first binder is less than 360 parts by weight, the pigment extender may not be well mixed with the first material, the water resistance of the paint film may deteriorate, and the paint film may flow down without being properly attached to the wall surface. If the content of the binder exceeds 400 parts by weight, workability during spraying may be greatly reduced and a uniform coating film may not be obtained.

At this time, in the dispersing step (S20), an anionic surfactant, a second antifoaming agent, a plasticizer, and a second pH adjusting agent may be further added.

The anionic surfactant may preferably be an aqueous solution of a sodium polymer of polycarboxylic acid, and a product called SN Dispersant 44S from Korea San Novco may be used. The anionic surfactant may serve to maintain the physical properties of the aqueous color bontile paint composition and improve the dispersibility of the inorganic pigment.

The anionic surfactant may be included in an amount of 1.8 to 2.0 parts by weight based on 100 parts by weight of the total composition. If the content of the anionic surfactant is less than 1.8 parts by weight, pigment precipitation and color separation may occur, which may cause a problem in that the paint film does not achieve a uniform color overall after spraying. Exceeding it will only result in increased production costs without a significant increase in effectiveness.

The second antifoaming agent may be additionally used as the same material as in the previous mixing step.

The second antifoaming agent may be included in an amount of 0.36 to 0.40 parts by weight. If the content of the second defoamer is less than 0.36 parts by weight, there may be a problem that the intrinsic color of the pigment is not properly expressed during painting, and if the content of the second defoamer exceeds 0.40 parts by weight, production costs increase without a significant increase in effect. will result in only

The plasticizer may preferably be diisobutyl adipate, and a product called DiBA may be used. Since the plasticizer has a low evaporation rate, it may remain in the paint film formed of the water-based color bontile paint composition for a long time and serve to impart high elasticity and flexibility.

The plasticizer may be included in 3.6 to 4.0 parts by weight. If the content of the plasticizer is less than 3.6 parts by weight, the elastic modulus and flexibility may be lowered, which may cause workability as well as the quality of the painted film after painting to deteriorate. If the content of the plasticizer exceeds 4.0 parts by weight, the strength of the painted film is lowered In addition, the viscosity of the water-based color von tile paint composition is too low, and a problem in that a part of the plasticizer is precipitated into the upper layer of the paint film during curing may occur.

The second pH adjusting agent may be the same material as the first pH adjusting agent in the previous mixing step, but the present invention is not limited thereto.

The second pH adjusting agent may be included in an amount of 1.0 to 1.3 parts by weight. If the content of the second pH adjusting agent is less than 1.0 parts by weight, the water-based color von tile paint composition may be excessively acidified, causing gelation or deterioration of physical properties such as storage stability. Exceeding 1.3 parts by weight only causes an increase in production cost without a significant increase in effect.

Next, a step (S30) of adding and mixing additional water, a second binder, and a waterproofing agent to the second material to adjust the properties of the water-based color von tile paint composition, A color bone tile coating composition can be prepared.

The second binder may preferably be an acrylic ether copolymer, and a product called cp-696 of Cheonho Polymer may be used. In the case of the first binder, there is a shortcoming in terms of price or in terms of expressing the color of the coating film. and can serve to increase viscosity and thixotropy.

28 to 32 parts by weight of the second binder may be included. If the content of the second binder is less than 28 parts by weight, a problem of deterioration in drying properties of the coating film may occur during painting work, and if the content of the second binder exceeds 32 parts by weight, workability is reduced due to high viscosity and the coating film is formed. A problem of shortening the lifespan of the coating film may occur due to moisture absorption over time.

The waterproofing agent may preferably use a silane-based waterproofing agent including a modified (soluble) silicate. The waterproofing agent serves to impart waterproofness to the water-based color von tile paint composition, thereby preventing contamination, salt damage and corrosion of the coating film, thereby extending the life of the painting film.

In general, pores and calcium hydroxide on the surface of concrete promote deterioration of concrete by allowing the surface to easily react with moisture, CO ₂ gas in the air, and acid pollutants.

Soluble silicate, which is designed to penetrate well into the pores of concrete, penetrates into pores and micro-cracks on the surface and chemically reacts with unreacted calcium hydroxide in concrete to generate insoluble calcium silicate hydrate (C-S-H) in the pores of concrete, unified At this time, the surface layer density, strength, and chemical resistance of the treated concrete can be improved.

In addition, in the silica molecule of soluble silicate, the terminal oxygen bonded to Si exists in the state of ≡Si-OH, and the oxygen near the alkali metal ion is ≡Si-O-Na+, ≡Si-O-K+ or ≡ It exists in the Si-O-Li+ state. When water evaporates or the state of the liquid silicate becomes unstable, a condensation polymerization reaction occurs between adjacent ≡Si-OH and ≡Si-OH, and the ≡Si-O-Si≡ bond develops three-dimensionally. When soluble silicate penetrates into the concrete surface, Ca+2 ions in the concrete are replaced with monovalent alkali metal ions to form calcium silicate hydrate in the form of ≡Si-O-Ca-O-Si≡ and participate in silica bonding.

CSH additionally generated in the concrete pores improves the density of the concrete surface layer, so that the strength, abrasion resistance, and water absorption resistance of the concrete surface increase. Since the calcium hydroxide component of the concrete surface has already been chemically stabilized by reacting with silicate, it is chemically stabilized by not reacting even when it comes in contact with moisture, CO ₂ gas in the air, or acid pollutants.

Due to this mechanism, the durability of concrete treated with soluble silicate can be improved and the life span can be extended. In addition, the surface of the concrete treated with the above reaction can improve not only water permeability and water absorption resistance, but also abrasion resistance, chemical resistance, and resistance to repeated freezing and thawing. Accordingly, the water-based color von tile coating composition of one embodiment may preferably have properties suitable for alkali cement or the like.

74 to 79 parts by weight of the waterproofing agent may be included. If the content of the waterproofing agent is less than 74 parts by weight, the waterproofness of the coating film is lowered, and various problems described above may occur.

And, in the adjustment step (S30), preservatives and strength enhancers may be further added.

As the preservative, isothiazolone may be preferably used, and a product called Acticide MVK from Thor Specialties may be used. The preservative may serve to inhibit the occurrence of mold in the water-based color bontile paint composition.

The strength enhancer may preferably use alumina silicate (Alumina Silicate), and a product called ESAI Co.'s Bead 100 may be used. The strength enhancer may serve to increase the strength of a paint film formed of the aqueous color bontile paint composition and extend the life of the paint film by imparting strength to arbitrarily generated curves (patterns). In addition, the strength enhancer may partially prevent paint from splashing during spraying using a nozzle, and may play a role of smoothing the spraying speed of the nozzle during spraying.

54 to 61 parts by weight of the strength enhancing agent may be included. If the content of the strength enhancer is less than 54 parts by weight, the strength of the coating film is weak, and there may be a problem of incontinence or cracks in the coating film. It slows down, and the strength improvement effect does not significantly increase, and only increases the production cost.

In general, in the case of this tile paint composition, if it has no elasticity or is smaller than the standard value, a splashing phenomenon (a phenomenon of dispersion or scattering when spraying the paint with a nozzle) occurs during spray painting, and the coating film is unnaturally finely angled Since it has a curved shape, the resistance to micro-deformation caused by various external factors is weakened, and the life of the coating film may be shortened.

The water-based color bontile coating composition of one embodiment is a one-component, eco-friendly water-soluble coating composition, which has excellent elasticity itself after a coating film is formed by the first and second binders and additives, and therefore, splashing does not occur during spray painting There is little or no aggregation in the coating film. In addition, since it is a water-based product, it can be easily used for exterior walls as well as interior walls of buildings.

In general, in the case of a building made of concrete, cracks may occur in the wall after a certain period of time due to seasonal temperature differences and vibration and shock caused by various external forces. In addition, when foreign matter or rainwater penetrates through these cracks, the building may be corroded or damaged.

However, when the inner or outer wall of a building is painted with the water-based color von tile coating composition of one embodiment, the paint film has excellent strength and increased elasticity, and thus incontinence or cracking in the paint film can be prevented. Therefore, the coating film formed in this way faithfully serves as a waterproof film on the outer wall of the building, effectively blocking the penetration of foreign substances or rainwater into the outer wall of the building without installing a separate waterproof mortar. Since corrosion and damage can be prevented in advance, it can be of great help in extending the life of a building.

In addition, the water-based color bontile paint composition of one embodiment contains a pigment extender and does not flow down the wall during spray painting and has little splashing, so that a high-quality paint film having various colors can be formed even with a single coating. After the painting is completed, not only does the coating film not easily become contaminated, but even if the wall surface is contaminated, it has the advantage of easy maintenance by simply washing it with water or a neutral detergent.

On the other hand, one of the reasons for spraying is to form an arbitrary three-dimensional pattern by giving a curve to the coating film. General paints cannot form curves (arbitrary patterns) because they flow down when curves are applied. In addition, when an attempt is made to form bends by simply increasing the viscosity by adding an excessive amount of additives, the workability is greatly reduced and the painting operation itself is practically impossible. However, the paint film formed from the water-based color von tile coating composition of one embodiment does not have this problem.

Hereinafter, a coating method using the eco-friendly water-based color von tile coating composition prepared as described above is described. First, various foreign substances attached to the surface of the inner or outer wall of the building to be painted are removed using air or water pressure.

Then, after painting the surface of the inner or outer wall of the building, if there is a crack, repair the cracked part on the surface of the inner or outer wall of the building.

Then, using a spray gun, etc., the surface of the inner or outer wall of the building to be painted is painted with the eco-friendly water-based color bontile paint composition prepared according to an embodiment and dried, at this time the intended color It is possible to obtain a coating film with a 3D pattern and a 3D pattern at the same time, so the painting work can be completed without separate color painting.

Next, if necessary, top coat is applied once more with the eco-friendly water-based color bontile paint composition of one embodiment using a gun to be sprayed on the surface of the inner or outer wall of the building, and dried for a certain period of time. Accordingly, it is possible to change the size of a desired three-dimensional pattern, thereby forming a three-dimensional pattern with a more distinct color.

The present invention is not limited by the above-described embodiment and the accompanying drawings, but is intended to be limited by the appended claims.

Therefore, various forms of substitution, modification, and change will be possible by those skilled in the art within the scope of the technical spirit of the present invention described in the claims, which also falls within the scope of the present invention. something to do.
