{Manufacturing method of water soluble coating composition having complex functionality}

The present invention relates to a method for manufacturing a water-soluble coating composition with complex functionality. The present invention relates to a method for producing a water-soluble coating composition with complex functionality. It improves the physicochemical and biological resistance of the composition that forms a coating film on the road surface and functions as a visual indicator, thereby improving functional properties such as adhesion, impact, corrosion, and abrasion.

Lanes are marked on the road surface for the purpose of distinguishing between driving directions and lanes. Paint compositions for lane markings can be classified into heating type, room temperature type, water-soluble type, fusion type, two-component type, etc.

In recent years, as environmental regulations on the emission of volatile organic compounds (VOC) have been strengthened, the paint industry, which uses a lot of organic solvents, has faced great difficulties. Accordingly, it became an opportunity to urgently replace solvent-based paints with environmentally friendly paints.

Specifically, the paint for road markings that has been used so far has the advantage of shortening the time required for complete drying after painting, thus shortening the traffic restrictions on the road during painting work. However, these road marking paints had a problem in that they lacked thermal stability over time, causing the paint to break or crack.

In particular, the water-soluble paint is a paint in which pigments and extenders are added to the synthetic resin, which is the main element of the paint film, and the desiccant, which is the minor element. The paint film is formed by physical adhesion, and is applied to the road surface at room temperature or in a heated state, and has night reflective performance and It has great advantages in terms of speed of construction, but it has disadvantages such as environmental pollution and low applicability to each type of labeling.

Hereinafter, the specific production method of the present invention will be described while its effects and actions will be explained, and the detailed description of the composition after step-by-step production will be described again through examples.

The present invention includes a basic material generation step (S100) of generating a basic material by mixing a reinforcing pigment that reinforces optical and mechanical properties with an acrylic resin whose skeleton is formed by a curing agent; A color mixture generation step (S200) of mixing colored pigments with the basic materials of the basic material generation step (S100) to create a color mixture; A coating composition creation step (S300) of forming a coating composition by mixing oxide-based ceramics with a hexagonal close-packed structure and coarse rock minerals prepared in the absence of water at high temperature to prevent sedimentation of the pigment; A composite composition forming step (S400) of mixing the color mixture and the coating composition to form a composite composition in which the color mixture and the coating composition are combined; It consists of a paint composition forming step (S500) of mixing a solution containing silver with the composite composition of the composite composition forming step (S400) to form a paint composition that prevents internal contamination and minimizes environmental pollution over time. It is characterized by the formation of an environmentally friendly paint composition that is resistant to wear and internal contamination due to environmental factors.

In the present invention, an antistatic agent, an antifreeze agent, a water-soluble wax, a plasticizer, a dispersant, and an antifoaming agent are additionally mixed to ensure the stability of the final resulting paint composition.

In more detail, the basic material generation step (S100) includes a basic resin generation step (S110) of generating a basic resin by inducing crosslinking of the acrylic monomer resin by mixing an acrylic monomer and an aziridine curing agent; Further comprising a reinforcing pigment addition step (S120) of mixing a water-soluble antistatic agent, anti-freeze agent, water-soluble wax, plasticizer, dispersant, and anti-foaming agent with the basic resin of the basic resin generation step (S110) to create a basic material. There is a characteristic.

In the basic resin creation step (S110), an aziridine curing agent, a crosslinking agent, can be used to promote the crosslinking reaction by reacting with the acrylic acid component of the resin. For this purpose, it is preferable to mix 70 to 80% by weight of acrylic monomer and 20 to 30% by weight of aziridine curing agent. If it is less than 20% by weight, reactivity may decrease due to the effect of the hardener, and if it exceeds 30% by weight, the excessive content of the hardener may increase the cost and affect strength, durability, water resistance, and weather resistance.

The reinforcing pigment addition step (S120) includes 70-75% by weight of base resin, 15-20% by weight of water-soluble antistatic agent using quaternary ammonium, 1-2% by weight of anti-freezing agent, and 1-2% by weight of water-soluble wax. , 1-2% of plasticizer, 1-2% of dispersant, and 1-2% of anti-foaming agent are mixed to create the basic material.

Due to the characteristics of the paint applied to the road and the characteristics of the resin itself, the addition of an antistatic agent can prevent the adsorption of dust even after the coating film is formed. This ultimately has the effect of preventing the labeling function from decreasing over time. In addition, anti-freeze agents prevent freezing depending on the moisture content of water-based paints, and water-soluble waxes are used to prevent poor drying and decreased durability when oxygen in the air reacts with the acrylic monomer used in acrylic resin.

In addition, the plasticizer prevents cracking of the paint film during the winter, the dispersant improves the visual effect, hiding power, and storage stability after the paint film is formed by improving the dispersion of pigments, etc. within the composition, and the antifoam agent is used during the mixing and stirring process or during paint application. Bubbles can occur and reduce physical properties, so removing these bubbles ultimately improves the appearance of the coating film.

The anti-freezing agent, water-soluble wax, plasticizer, dispersant, and anti-foaming agent are added from the basic material using at least 1% by weight to ensure that each pigment is uniformly mixed when mixed with agitation several times in the future process, and all pigments added to the final paint composition. Stability can be maximized by stirring.

The color mixture generation step (S200) is a step of mixing a colored pigment with a basic material. The colored pigment is a colored powder that is insoluble in water, oil, and solvents, and provides coloring and hiding power while embodying the color of the paint.

The present invention is characterized by producing a color mixture by mixing 25 to 50 wt% of colored pigment with 50 to 75 wt% of the basic material.

If the total amount of these colored pigments is less than 25% by weight, the coloring and hiding power of the paint may be reduced, and if it exceeds 50% by weight, wettability and adhesion become low and viscosity increases, causing problems that greatly reduce productivity and workability. can do.

In the coating composition creation step (S300), alumina and silica are prepared and later stirred with the color mixture to control the strength and durability of the coating film of the coating composition.

Alumina has a high melting point, thermal stability, and hardness next to diamond, silicon carbide, and boron carbide, and has excellent electrical insulation and stability against acids and alkalis. Silica has acid resistance, alkali resistance, and heat resistance. It has very high hardness and can be safely mixed with all powder raw materials without chemical reaction. As a functional pigment with high chemical stability, it has excellent warning properties and is used in various paints.

Specifically, alumina and silica are materials with different particle sizes and need to be formed uniformly for the thickness stability and appearance of the coating film.

Accordingly, the present invention includes an alumina preparation step (S310) of preparing alumina in a micrometer size; Silica preparation step of preparing micrometer size (S320); It is characterized in that it further includes a uniform mixing step (S330) of uniformly mixing alumina and fumed silica to form a coating composition.

Furthermore, in order to obtain better physical properties for the paint composition, aluminum oxide is prepared in a micrometer size in the alumina preparation step (S310), and silicon dioxide is prepared in the silica preparation step (S320). It includes preparing it in a micrometer size and mixing it uniformly in the coating composition mixing step (S330).

The composite composition forming step (S400) is a step of mixing the color mixture and the coating composition to form a composite composition in which the color mixture and the coating composition are stirred,

Reinforced by further including a composite composition high-speed mixing step (S410) in which 70% by weight of the color mixture and 30% by weight of a coating composition in which aluminum oxide and silicon dioxide are uniformly mixed are mixed at high speed to form a composite composition. It is possible to create a composite composition with excellent physical properties, that is, resistance to wear and excellent cutting strength and tensile strength.

At this time, uniform mixing of aluminum oxide and silicon dioxide refers to mixing them in a 1:1 ratio.

The paint composition forming step (S500) is a step of adding and stirring a nano-sized silver (Ag) solution with excellent antibacterial activity to form an eco-friendly coating film to respond to environmental regulations that are currently emerging,

Silver (Ag) has excellent antibacterial properties, so it has the effect of preventing the collapse of the paint film due to the action of microorganisms. It also enables storage stability, that is, long-term preservation of the paint, and unlike preservatives, silver (Ag) has little environmental pollution. It is possible to produce an eco-friendly paint composition.

Accordingly, the present invention further includes a silver nano high-speed mixing step (S510) in which 1% by weight of nano-sized silver solution is mixed with 99% by weight of the composite composition at high speed to form a paint composition, and the silver nano solution is coated on the surface of the composite composition. It is characterized by creating a composition and allowing this paint composition to have its own resistance to contamination.

The composite composition high-speed mixing step (S410) and the silver nano high-speed mixing step (S510) are preferably mixed using a high-speed mixing machine of 1700 rpm or more. If it is lower than this, the mixing between each pigment is not sufficient, which may cause a decrease in the physical properties of the resulting paint composition later. You can. Of course, if the manufacturing time increases during the manufacturing process, the manufacturing cost per time will drop.

Hereinafter, the advantages and features of the present invention will be explained in more detail through examples of physical property tests of the coating composition of the present invention.

A coating composition produced by stirring 1% by weight of silver nano solution with 99% by weight of a composite composition produced by high-speed mixing of 30% by weight of a coating composition in which aluminum oxide and silicon dioxide are uniformly mixed was applied to a polyethylene plate. A coating film was made with a thickness of approximately 1 mm and the physical properties (electrical resistance, contamination resistance, abrasion resistance, hardness, adhesion, and antibacterial power) were tested.

70% by weight of acrylic monomer, 75% by weight of base resin mixed with 30% by weight of aziridine hardener, 20% by weight of water-soluble antistatic agent using quaternary ammonium, 1% by weight of anti-freeze agent, 1% by weight of water-soluble wax, 1% by weight of plasticizer. After mixing the basic materials by mixing 1% by weight of dispersant and 1% by weight of defoaming agent, 50% by weight of the basic material is mixed with 50% by weight of colored pigment to create a color mixture, and then 70% by weight of the color mixture and aluminum oxide (aluminum oxide) are mixed. A coating composition produced by stirring 99 wt% of a composite composition produced by high-speed mixing of 30 wt% of a coating composition obtained by uniformly mixing oxide and silicon dioxide and 1 wt% of a silver nano solution was spread on a polyethylene plate with a thickness of about 1 mm. A coating film was made of different thicknesses and the physical properties (electrical resistance, contamination resistance, abrasion resistance, hardness, adhesion, and antibacterial power) were tested.

70% by weight of acrylic monomer, 75% by weight of base resin mixed with 30% by weight of aziridine hardener, 20% by weight of water-soluble antistatic agent using quaternary ammonium, 1% by weight of anti-freeze agent, 1% by weight of water-soluble wax, 1% by weight of plasticizer. After mixing the basic materials by mixing 1% by weight of dispersant and 1% by weight of defoaming agent, 50% by weight of the basic material is mixed with 50% by weight of colored pigment to create a color mixture, and then 70% by weight of the color mixture and aluminum oxide (aluminum oxide) are mixed. oxide) and 60 wt% of silicon dioxide. The coating composition produced by mixing 98 wt% of the composite composition produced by high-speed mixing of 30 wt% of the coating composition mixed with 40 wt% of silicon dioxide and 2 wt% of the silver nano solution was mixed with polyethylene. A coating film with a thickness of approximately 1 mm was made on the plate and the physical properties (electrical resistance, contamination resistance, abrasion resistance, hardness, adhesion, and antibacterial activity) were tested.

The manufacturing method of Example 3 was followed, but only the antistatic agent was changed to 15% by weight of an antistatic agent for acrylic to prepare a base material. The coating composition was applied to a polyethylene plate to form a film with a thickness of about 1 mm and the physical properties (electrical resistance, contamination resistance, resistance to contamination) were prepared. Abrasion, hardness, adhesion, antibacterial power) were tested.

The manufacturing method of Example 1 was followed, but 98% by weight of the composite composition produced by high-speed mixing 30% by weight of a coating composition of uniformly mixed aluminum hydroxide (Al(OH) ₃ (aluminum hydroxide) 3 (aluminum hydroxide) and silicon dioxide instead of aluminum oxide) and a silver nano solution were added. The paint composition produced by stirring 2% by weight was applied to a polyethylene plate to form a film with a thickness of approximately 1 mm, and the physical properties (electrical resistance, contamination resistance, abrasion resistance, hardness, adhesion, and antibacterial power) were tested.

The method for evaluating the physical properties of the examples prepared as above is explained as follows.

Electrical resistance was measured using an electric resistor in an environment of 35% to 45% humidity. Pollution resistance was measured by generating static electricity on the surface using tobacco ash with a low particle density, and then determining the presence or absence of cigarette ash remaining on the surface layer as Fail/Pass. Evaluated and marked.

The abrasion resistance measurement method was to reciprocate the steel wool 20 times with a load of 1 kg and evaluate it as grade 1 to 3 through visual observation. If it did not meet the grade 3 standard, it was marked as unsatisfactory. Specifically, if there were no scratches or blemishes on the surface layer, it was marked as grade 1, if there were small grooves, it was grade 2, if multiple grooves were formed and the surface was not beautiful due to excessive scratches, it was graded as grade 3, and if it was below the grade 3 standard, it was marked as unsatisfactory.

The adhesion measurement method was evaluated and marked as Fail/Pass depending on the presence or absence of peeling between the polyethylene plate and the coating film created with the paint composition.

The antibacterial properties were evaluated in accordance with JIS Z 2801 using Staphylococcus aureus and Escherichia coli, which were cultured for 24 hours at 35 ± ℃ and RH 905 ± ℃, followed by measuring the number of bacteria.

division Example 1 Example 2 Example 3 Example 4 Example 5 electrical resistance 7.1x10 ¹⁰ 7.1x10 ¹⁰ 7.1x10 ¹⁰ 4.4x10 ⁹ 4.1x10 ¹⁰ Staining resistance P P P F F wear resistance 1st grade 1st grade level 3 level 3 Below grade Adhesion P P P P F Antibacterial power
(decrease rate%) 99.9 98 98 98 98

As shown in Table 1 above, when changing from a water-soluble antistatic agent using quaternary ammonium to an acrylic antistatic agent, the electrical resistance was very low and the contamination resistance did not meet the standard, resulting in a Fail grade.

In addition, when more silicon dioxide was mixed with 40% by weight of aluminum oxide and 60% by weight of silicon dioxide, the wear resistance was lowered. In particular, when the paint composition was formed by changing aluminum oxide to aluminum hydroxide (Al(OH) ₃ ), peeling phenomenon was observed, and both contamination resistance and wear resistance were judged below the grade standards.

In addition, since the antibacterial effect of the silver nano solution does not lead to significant results as the amount of the solution increases, it is preferable to add 1% by weight according to the present invention.

As described above, the present invention improves the physicochemical and biological resistance of the composition that forms a coating film on the road surface and functions as a visual marker, thereby complementing the complex functionality of adhesion, impact, corrosion, and abrasion, etc. to be used on the road. Due to the characteristics of the paint composition, its resistance to wear, corrosion, and contamination is greatly increased, which can reduce social costs by increasing the time required for repair work.

In order to explain the above operation, effect, configuration, and operation, reference is made to an embodiment shown in the drawings, but this is merely illustrative, and those skilled in the art will be able to make various modifications and other equivalent embodiments from this. It should be made clear that it is possible.
