Description

Colored transparent coating solution, preparation method and coated substrate TECHNICAL FIELD

The present invention relates to producing a transparent coating liquid with a color by realizing color through a pigment dispersion and mixing it with an organic resin and various additives. In addition, the present invention relates to a substrate to which such a coating liquid can be applied, and a coating pattern that is effective in terms of coating upon the substrate.

Recently, colored transparent glass, which gives color to the luxurious image of glass, has been widely used as interior and exterior building materials. For example, color glass which coated the coating material to glass, laminated glass which put resin or a film between two pieces of glass, and the color glass which put the metal additive at the time of glass manufacture, etc. are manufactured.

However, in the case of the color glass coated with the paint, due to the size of the pigment contained in the paint attached to the glass has a concealability that all light does not transmit. In the case of laminated glass, it is possible to maintain transparency by putting colored transparent resin or film between two pieces of glass to have a color.However, by using a dye that is weak in ultraviolet light to express such a color, compared to a pigment used as time passes. Discoloration proceeds rapidly.

Therefore, in recent years, colored glass prepared by adding a metal additive can express all colors while having transparency, and is also used for interior and exterior building materials because it is strong in ultraviolet rays.

However, colored glass manufactured with metal additives currently used for interior and exterior building materials uses heavy metals in the manufacturing process, causing environmental pollution, and due to limited production in consideration of profitability, the color is colored by each manufacturer such as Green, Blue, and Bronze. Due to the limited production / sale, it is unable to adequately respond to the color and quantity preferred by the customer.

In addition, such a coating solution is a conventional case that is conventionally applied to the glass and it was difficult to apply to other materials. In addition, if color is applied to the coating solution and transparency is secured, the effect of the stereoscopic effect and aesthetic value of the pattern may be increased according to the visual pattern type using the same.

As a result, research has been conducted on a coating composition that can be coated on glass and exhibit various colors while maintaining transparency, and the substrate to which such a coating liquid can be applied has also been applied to various materials away from typical glass.

According to one aspect of the present invention it is possible to implement a coating liquid having a transparency at the same time the color is applied, it is possible to apply the coating liquid to a variety of substrates can bring a variety to the coating industry, through the pattern using the coating liquid and the three-dimensional effect and By maximizing the aesthetic effect, it is possible to preoccupy an advantageous position in the industry where coating liquid is used for exterior of buildings and the like today.

Figure 1 is an embodiment of a method for increasing the steric effect or aesthetic effect by applying a coating solution according to one aspect of the present invention to a substrate and patterned it.

The coating liquid according to one aspect of the present invention is a coating liquid having a very transparent shape compared to the coating liquid for screen printing which is conventionally used. In addition, the printability according to materials such as glass, metals and plastics is kept constant, and exhibits very flat surface leveling. In addition, the process stability is also high because no harmful substances such as hydrofluoric acid (HF) used in the conventional glass etching process are used.

The coating solution according to an aspect of the present invention may include an organic resin having an acryl group, a viscosity control solvent, an antifoam additive, a surface fluid additive, an adhesion improving additive, and a pigment dispersion.

The organic resin having an acryl group is used to maintain the transparency of the coating solution and may be composed of an organic copolymerizable copolymer. As one example, at least one copolymerized with methyl methacrylate, ethyl methacrylate and butyl methacrylate may be used. In addition, at least one selected from the group containing methyl methacrylate, ethyl methacrylate and butyl methacrylate, styrene and vinyltoluene At least one copolymerized with at least one selected from the group consisting of) may be used.

The viscosity adjusting solvent may be used to maintain or control the viscosity of the coating liquid in printing the coating liquid on the substrate. Such a viscosity control solvent may be composed of a material having a high boiling point and good solubility in polar resins and fats. One example is diethylene glycol monobutyl ether acetate or diethylene glycol monoethyl, which has a high boiling point, is soluble, and has a fruity flavor and is widely used as an adhesive or a solvent. ether acetate).

The antifoam additive may use a material that is not compatible with the coating solution to increase the incompatibility of the resin and to quickly remove the bubble film. In order for the antifoaming agent to penetrate the interface between foam and paint, the surface tension must be lower than that of the resin and the interface tension with the resin should be appropriate. In addition, since the bubble is not completely mixed with the resin and the bubble has a difference in density between the resin and the surface tension of the antifoaming agent, the surface floats quickly on the surface of the paint, or the air bubbles formed on the surface of the coating film cause partial surface tension decrease due to the adsorbed antifoaming agent. Additives on the principle of breaking the membrane can be used. One example may be composed of dimethyl siloxy-polyfluoro methyl siloxypoly methyl siloxy-copolymer, which is a polysiloxane copolymer.

The surface fluid additive is for the wettability of the printing material, the leveling of the flatness of the surface, and the reduction of the surface tension. The surface-flow additive may be a silicon compound because the silicon and the organic polymer interact with each other to form an organic-silicon composite having an alkoxy functional group and form a film having a very high crosslinking density by coupling or condensation. . One example may be a silicone acrylate (silicone Acrylate) having a polysiloxane copolymer (polysiloxane copolymer).

The adhesion improving additive may be a material that improves the adhesion through strong bonding with the resin or inorganic material. In particular, a very chemically stable bond is formed through hydrogen bonding with the resin, and the inorganic material is adsorbed through hydrogen bonding, and when dried and treated, a strong chemical is obtained through the dehydration condensation reaction in which water generated through chemical bonding is released. The bond is made. Therefore, it is possible to obtain an effect of increasing adhesion to various substrates as well as glass by connecting organic materials and inorganic materials, which are usually difficult to bind significantly. One example may include a silane coupling polymer compound having an amino and an epoxy reactor, or a methoxy and an ethoxy reactor simultaneously.

In addition, the polymer compound is a compound capable of forming a hydrogen bond, for example, 3-glycidoxypropyltriethoxysilane, 3-aminopropyltrimethoxysilane, or 3 -Aminopropyltriethoxysilane (3-aminopropyltriethoxysilane).

The pigment dispersion is composed of an organic pigment, a dispersant and a solvent, the solvent may be the main component. Specifically, the organic pigment may include 1 to 30 wt%, dispersant 1 to 30 wt%, and solvent 40 to 98 wt%.

The organic pigment refers to a pigment of an organic compound which is mainly insoluble in water, and may be used alone or in combination to exhibit a desired color. The amount of the organic pigment may be used in an amount of 1% to 30% by weight based on 100% by weight of the pigment dispersion, and the dispersion stability of the organic pigment may be deteriorated when the amount of the organic pigment exceeds 30% by weight. In one embodiment, a compound capable of realizing a stable color is used. For example, azo, phthalocyanine, quinacridone, dioxazine, and perylene )-, Quinophthalone-based, quinophtalone-based, isoindolinone-based, isoindonine-based or di-pyrrolo-pyrrole-based may be used. It is also possible to use organic pigments having a primary particle size of 10 to 200 nanometers.

The dispersant may serve to wet the solid particles in the dispersion medium, assist in grinding, and prevent reaggregation of the particles. For this purpose, a nonionic polymer dispersant having an amine value of 10 mgKOH / g or less may be used. Two or more kinds can be mixed and used. One embodiment may include a polyester-based, polyacrylate-based, polyurethane (polyurethane) or polyether (polyether).

The solvent is used to dissolve the resin or to dilute the paint. Since most of the organic pigments are non-polar, they are generally insoluble in polar solvents such as water, but the actual pigment contains a small amount of impurities. In many cases, the polarity of the solvent needs to be suppressed so that such impurities do not melt.

In addition, by adjusting the polarity of the solvent, it is possible to improve the dispersion of the pigment without causing agglomeration of the pigment in the paint and to improve the solubility of the resin and the solubility of the dispersant at the same time. Paint can be obtained.

Such solvents may be used in an amount of 40% to 98% by weight based on 100% by weight of the pigment dispersion, for example, diethylene glycol monoethylether acetate, propylene glycol monomethyl ether monomethylether, propylene glycol monomethylether acetate, propylene glycol monoethylether, propylene glycol monoethylether acetate, methyl cellosolve, ethyl cello Ethyl cellosolve, epoxy propionic acid, xylene, toluene, ethyl acetate, methyl acetate, butyl acetate, methyl ethyl ketone ( methyl ethyl ketone, cyclohexanone, butanol , Ethanol, methanol or isopropanol may be used alone or in combination of two or more thereof.

Hereinafter, the method for producing the coating liquid will be described in detail.

First, the organic resin having an acryl group and the viscosity control solvent may be stirred together. At this time, the stirring may be continued for 10 to 20 minutes at 200 to 600rpm.

The resin solution obtained through the above process may be subjected to agitation by adding an antifoam additive, a surface fluid additive, and an adhesion enhancing additive. At this time, the stirring may last 10 to 50 minutes at 400 to 600 rpm, and as a result, a transparent color composition may be prepared.

Adding a pigment dispersion to the transparent color composition may be added. Through this, the coating liquid according to one side of the present invention is prepared.

The coating liquid prepared by one aspect of the present invention has a high applicability to a substrate. Therefore, the present invention can be applied not only to glass but also to a substrate based on a metal or a polymer compound.

The glass may include all of a variety of glass generally used in industry, and may include, for example, general glass, tempered glass, or low iron glass.

The metal may include all the metals used in the field requiring application of the coating liquid, and may include, for example, stainless steel or aluminum (Al).

The polymer compound may also include all polymer compounds used in fields requiring application of a coating solution, and may include, for example, acryl or polycarbonate.

In addition, the coating liquid according to one aspect of the present invention may include a color coating liquid and a transparent coating liquid, the color coating liquid is an organic resin having an acrylic group (acryl group), viscosity control solvent, antifoam additives, surface fluid additives, adhesion strength improvement Including an additive or pigment dispersion, the transparent coating liquid may include an organic resin having an acryl group, a viscosity control solvent, an antifoam additive, a surface fluid additive or an adhesion enhancing additive. That is, the color coating liquid and the transparent coating liquid may be distinguished according to the presence of the pigment dispersion.

Since the transparent color coating liquid according to one aspect of the present invention implements color and also has transparency, the stereoscopic effect and the aesthetic effect of the pattern can be maximized by the pattern of the transparent coating liquid having various colors. Referring to Figure 1, for example, by arranging a transparent coating liquid having a variety of colors on a substrate and surrounding the coating liquid and coating a transparent coating liquid may exhibit a three-dimensional and aesthetic effect that the shape having a color in the interior, and various colors Eggplants can be arranged on the substrate, and the coating liquid surrounds the coating liquid and coats the transparent coating liquid having various colors again to derive the stereoscopic and aesthetic effect of overlapping colors. In addition, by coating a transparent coating liquid on a substrate and then coating the coating liquid having a certain form with a coating liquid having various colors, the shape having a color from the substrate may have a three-dimensional effect and realize an aesthetic effect.

After the aesthetic coating, a coating layer may be further added, which serves as a protective role, and a general protective coating liquid that performs functions such as durability, scratch resistance, or UV blocking may be used.

In order to increase durability, a protective coating including a polymer resin composite or a metal compound composite may be used. For example, a protective hard coating agent including a composite of acrylic, urethane, epoxy, styrene, or polyester may be used.

In addition, it is possible to use a coating agent comprising an acrylic polymer resin that maintains adhesion to a material and a print coating and a sol-gel organic-inorganic composite structure of an inorganic ceramic exhibiting a strong hardness against external impacts and scratches, which shows a very strong surface hardness. .

In addition, a self-healing coating agent containing urethane acrylate may be used for the scratch-resistant function, which has a self-healing function to impart elasticity even under a thin film condition and is pressed against an external impact. have.

In addition, a coating agent including zinc oxide (ZnO), titanium oxide (TiO ₂ ) or cerium oxide (CeO ₂ ), an organic material, a light stabilizer (quencher), and an UV observer may be used for the UV blocking function.

The most influential factors in the present invention are resin compositions and additives, and surface additives and adhesion force additives are additives for flatness, printability and adhesion properties of additional coatings. Comparative Example 4 is a result of printing another type of acrylic resin. Compared with Comparative Examples 1 and 2, the boiling water test is not satisfactory and the hardness and coating performance are relatively poor. In addition, it is not transparent and after curing, a milky white film is formed.

Color application design through the composition in the present invention is as shown in Figure 1 (a) is shown as forming a color coating composition after forming the design in a transparent pattern on the substrate. The transparent pattern coating layer is certainly protected. (b) forms a design by color full-printing on top coat after forming a color pattern on the substrate. In the overlapping part of the color printing, color and transparent color appear. Color separation allows for near-realistic printing. (c) was a transparent pattern coating after the color coating on the substrate. Because of this, the surface three-dimensional effect by the transparent pattern is maximized. Example 3 and Comparative Example 2 is a top protective coating on the color front coating, Comparative Example 2 is a top protective coating and the three examples were applied a top protective coating of the G, H, I composition. Printable materials are shown in Table 2 below.

Referring to Table 3, it is possible to confirm the increase in the surface properties of the topcoat coating in Example 1 by applying the topcoat coating. G1 coating is composed of an acrylic polymer resin that maintains adhesion to the material and print film, and a sol-gel organic-inorganic composite structure of inorganic ceramics that exhibits hardness resistant to external impact and scratches. Because of this, it shows very strong surface hardness. In Example 2 it can be seen that the scratch-resistant function of the G2 coating having a self-recovery function. Topcoat protective coatings give elasticity even under thin film conditions and have an effect of spreading slowly over time. As in Comparative Example 3, the UV blocking effect of the G3 coating agent can be confirmed. By adding zinc oxide (ZnO) and titanium oxide (TiO ₂ ) to block or absorb light in the UV region, UV blocking performance of more than 90% is realized. G3 coating agent with UV-blocking ability effectively prevents discoloration and discoloration of undercoat.

The top coat coating agent is configured as follows.

1. Optically clear coating composition for top coat protection, which is a composite of acrylic, urethane, styrene, epoxy and ester

2. Hard coating solution of sol-gel organic-inorganic composite resin which is a compound of acrylic polymer resin and inorganic ceramic

3. Self-healing coating agent of urethane acrylate with self-healing function

4. UV blocking protective coating agent having UV blocking function by adding zinc oxide (ZnO) and titanium oxide (TiO ₂ ) to the above
