Description

FIELD OF THE INVENTION [0001] The present invention relates to a coating composition for infrared rays and ultraviolet rays,

The present invention relates to an infrared ray and ultraviolet ray shielding coating composition and a coating method thereof, and more particularly, to an infrared ray and ultraviolet ray shielding coating composition for shielding infrared rays and ultraviolet rays from sunlight by coating on a window glass or the like, And a coating method thereof.

In buildings with glass windows, heat and insulation directly relate to efficient use of energy, heating and cooling performance, and CO2 emissions. Ultraviolet rays having a wavelength range of about 10 to 400 nm and ultraviolet rays having a wavelength range of 700 nm or more among the sunlight spectrum generate heat and cause temperature rise. More than 60% of household energy consumption is used for heating and cooling, and the energy that passes through windowpanes is about 20 ~ 30%. Accordingly, in order to efficiently manage the room temperature, various methods of increasing the heat and insulation performance of the window glass have been applied. Accordingly, in order to efficiently manage the room temperature, various methods of increasing the heat and insulation performance of the window glass have been applied. Especially, it required glass or related compensators that can adjust transparency and transmittance so that infrared rays having heat energy of about 50% or more of solar energy can be seasonally heated or insulated and appropriately utilized.

For example, a method of controlling the transmittance of infrared rays by inserting a low-E (low-emissivity) glass into a window glass is known. In this method, Roy glass is placed between ordinary glass, and a metal such as silver having a high reflectance of infrared rays or metal oxide is coated by thinly coating or coating by a coating method such as sputtering or CVD method to improve the heat insulating performance. Window glass containing Roy glasses is known to have low emissivity and low emissivity. When installed in a building, the effect of insulation is large, which helps to save energy. Roy's glass is often processed in multiple layers rather than as a single piece due to its nature. Make sure that the coated side is on the outside of the inner pane glass. The metal film is an energy-saving glass that transmits the visible light to increase the light-emitting property of the room, and reflects the infrared rays to minimize the movement of indoor and outdoor heat, thereby reducing the temperature change of the room. In particular, Roy's double-layered glass has the advantage of being a high-insulation double-layered glass and displaying various colors because it is coated with a metal film having excellent heat insulation effect on the plate glass.

The types of Roy glasses are classified into a hard low-E film by a pyrolytic process and a soft low-E film by a sputtering process according to a coating preparation method. The hardrooy coating is produced by spraying a metal solution or powder onto the surface of a glass plate during the process of manufacturing a glass plate and by thermal coating. The coating material is a single metal oxide (SnO2) material. The advantage of the present invention is that it is possible to perform heat treatment such as strengthening by strong coating hardness and durability due to thermal coating. In contrast, in the method of manufacturing a soft roux coating, silver (Ag), titanium (Ti) It is produced by multilayer thin film coating of metals such as stainless steel. Advantages are high transparency, various colors can be realized by using various metals, and optical performance and thermal performance are known to be excellent. However, coating hardness and durability are poor compared with hard coating, and edge stripping treatment facility .

However, since the infrared ray blocking effect of the low-grade glass is small and the long-wave radiant heat of the room is prevented from flowing out due to the long-wave reflection effect of the heat ray, the indoor temperature rises and the problem of the cooling load increase occurs. Has an increasing problem. In addition, since expensive equipment is used for coating using sputtering or CVD, the cost is increased and the process proceeds under a precise atmosphere, which leads to a problem of poor mass productivity. Roy glass can be applied to building construction, but its use is limited because it can not be applied to buildings already completed or existing buildings.

Another method is a method of forming an infrared shielding film by applying a wet coating agent prepared by evaporating a phthalocyanine-based infrared absorbing dye to a film or by directly solubilizing it in an organic solvent to form a liquid coating material. Such a dye having an infrared absorption characteristic has a disadvantage in that transparency is lowered because a desired infrared ray shielding performance is realized by applying a large amount of dye, and there is a problem such as discoloration and discoloration upon exposure to direct sunlight. Korean Patent Application No. 10-2010-0055686 discloses an ultraviolet and infrared absorption blocking film using an inorganic oxide and a manufacturing method thereof.

Another method is physico-chemical deposition using a conductive oxide such as ATO (antimony tin oxide), ITO (indium tin oxide) or the like, or a wet coating agent obtained by dispersing the coating material into a coating material. This method, which occupies most of the infrared ray shielding film, has an excellent IR blocking property but has a problem of low transparency. In particular, in the case of ITO (indium tin oxide), it is necessary to switch to a substitute material due to depletion of indium to be.

Korean Patent Laid-Open Publication No. 10-2014-0033857 discloses that 10 to 50% by weight of a substance having properties of being cured by ultraviolet irradiation, 0.5 to 5% by weight of a compound capable of absorbing ultraviolet rays to form radicals, Discloses an ultraviolet curable coating liquid composition having a phase transition property comprising 20 wt% to 20 wt%, a dispersing agent 0.1 to 5 wt%, a leveling agent 0.1 to 5 wt%, and a solvent 15 to 88.3 wt% According to the phase transition characteristics, reversible switching is possible that blocks infrared rays at high temperatures in summer and transmits infrared rays at low temperatures in winter.

There are various proposals for coating the window glass with infrared rays and ultraviolet ray shielding coating agent, a glass coated with a coating agent, and a coating film attached to a glass to control the sunlight flowing into the room. However, There was no proposal to functionally satisfy. The inventor of the present application has found that it is possible to easily and rapidly apply a coating layer by applying an infrared ray and ultraviolet ray shielding coating agent on a glass surface that has been applied to a building or a structure, Coating compositions that can be used as heat and insulation, and new coating methods have been developed.

Hereinafter, embodiments of the present invention will be described as first to third embodiments, and will be described with reference to FIGS. 1 to 3. FIG.

1st Example

As shown in FIG. 1 (a) and FIG. 1 (b), the coating composition is formed by forming a coated cured coating on the inner or outer surface of the glass 100 to form a coating layer 200, And blocks or partially transmits infrared rays and ultraviolet rays contained in the light ray a. Then, the heat radiated from the infrared ray of the sunlight a is guided to the heat absorbing ⓔ through the thick section of the glass (100), and is radiated to the outdoor side and the indoor side c. Part of the absorption heat absorbed in the glass 100 is reflected directly by the coating layer 200. [

Second Example

The infrared and ultraviolet barrier coating composition according to the second embodiment of the present invention comprises 0.01 to 5% by weight of cesium tungsten oxide, based on the total weight of the composition; 23 to 35% by weight of an acrylic resin; 0.1 to 7% by weight of 2- (2H-benzotriazol-2-yl) -p-cresol; 23 to 35% by weight of butyl acetate; 1 to 19% by weight of 1-methoxy-2-propyl acetate; And 10 to 20 wt% of Ethylene Glycol Monobutyl Ether Acetate.

As shown in FIG. 1 (a) and FIG. 1 (b), the coating composition is formed by forming a coated cured coating on the inner or outer surface of the glass 100 to form a coating layer 200, It blocks or partially transmits the infrared rays and ultraviolet rays contained in the light beam a.

The infrared and ultraviolet barrier coating composition according to the first and second embodiments of the present invention may be formed by forming a coating film on the surface of the glass 100 with the coating layer 200 to shield a part of the infrared rays and ultraviolet rays of the sunlight, And the remaining part is transmitted to the room side or part of the absorption heat is emitted.

The amount of heat that is transmitted through the glass 100 or absorbed by the glass surface varies depending on the glass thickness and the cross-sectional area, the thickness of the coating layer 200, and the composition ratio. The adjustment of the desired amount of heat absorption can be freely adjusted by setting the standard.

In this case, the ratio of heat consumed to the outdoor side is ⓑ + ⓒ, and the amount of heat flowing into the indoor side is ⓓ + ⓔ. Such adjustment is possible by previously calculating the glass thickness, light transmittance and transmission area, and by designing the composition ratio of the coating composition and the thickness of the coating layer.

The coating method of the infrared and ultraviolet barrier coating agent according to the embodiment of the present invention can be carried out by the first method to the third method. This will be described with reference to the coating method explanatory diagram of FIG.

First Method

The coating method of the infrared ray and ultraviolet barrier coating agent according to the first method is a method of obtaining the coating layer 200 by coating the surface of the glass 100 with an infrared ray and ultraviolet barrier coating agent. Here, the coating agent to be used may be selected from the group consisting of 0.01 to 5% by weight of cesium tungsten oxide, 23 to 35% by weight of acrylic resin, 0.1 to 7% by weight of 2- (2H-benzotriazol- 23 to 35% by weight of butyl, 1 to 19% by weight of 1-methoxy-2-propanolacetic acid and 10 to 20% by weight of epilen glycol monobutyl ether acetic acid.

First, the application amount of the coating agent is metered quantitatively in the range of 20 to 30 g per 1 m < 2 > of the surface of the glass (100). The weighed coating is then soaked in the application roller. The coated layer 200 is obtained by coating the surface of the glass 100 with an infrared ray and ultraviolet ray shielding coating agent in the order of drying and curing in air.

Second Method

The second method is a method of coating the infrared ray and ultraviolet barrier coating agent by coating the surface of the glass 100 with an infrared ray and ultraviolet barrier coating agent to obtain the coating layer 200. Here, the coating agent to be used may be selected from the group consisting of 0.01 to 5% by weight of cesium tungsten oxide, 23 to 35% by weight of acrylic resin, 0.1 to 7% by weight of 2- (2H-benzotriazol- 23 to 35% by weight of butyl, 1 to 19% by weight of 1-methoxy-2-propanolacetic acid and 10 to 20% by weight of epilen glycol monobutyl ether acetic acid.

First, the surface of the glass 100 to be coated with the coating agent is selected and a releasing agent (not shown) is bonded. Then, the application amount of the coating agent is quantitatively measured in a range of 20 to 30 g per 1 m 2 of the glass surface, and the metered coating agent is wetted on the application roller. Then, the coating layer is formed by rubbing the surface of the releasing agent adhered to the glass surface with the application roller, and the infrared ray and ultraviolet ray blocking coating agent are coated on the surface of the glass 100 through the air drying and curing steps, .

Third Method

The third method is a method of coating the infrared ray and ultraviolet barrier coating agent by coating the surface of the glass 100 with an infrared ray and ultraviolet barrier coating agent to obtain the coating layer 200. Here, the coating agent to be used may be selected from the group consisting of 0.01 to 5% by weight of cesium tungsten oxide, 23 to 35% by weight of acrylic resin, 0.1 to 7% by weight of 2- (2H-benzotriazol- 23 to 35% by weight of butyl, 1 to 19% by weight of 1-methoxy-2-propanolacetic acid and 10 to 20% by weight of epilen glycol monobutyl ether acetic acid.

First, the coating agent is metered quantitatively in the range of 20 to 30 g per 1 m < 2 > of the surface of the glass (100). The weighed coating is then soaked in the application roller. Then, a coating agent is applied to the surface of the glass to form a coating surface, and a releasing agent (not shown) is deposited on the surface of the coated surface. The infrared ray and ultraviolet barrier coating agent are coated on the glass 100 To form a coating layer (200).

According to the coating method, a coating film is formed on the surface of the glass 100 to coat the infrared ray and the ultraviolet rays of the sunlight, or to reflect or radiate a part of the sun ray, 0.01 to 5 wt% of cesium tungsten oxide, 23 to 35 wt% of acrylic resin, 0.1 to 7 wt% of 2- (2H-benzotriazol-2-yl) -picresol, By using a coating composition composed of 35 to 35% by weight of 1-methoxy-2-propanolacetic acid and 1 to 19% by weight of epilene glycol monobutyl ether acetic acid and 10 to 20% The amount of heat absorbed can be adjusted or designed to have a desired performance according to the conditions of use depending on the thickness and the cross-sectional area of the glass, the thickness of the coating layer 200, and the composition ratio.

In addition, according to the coating method according to the embodiment of the present invention, as shown in FIG. 3, it is possible to easily and simply apply the coating agent uniformly on the glass surface with uniform thickness, smoothness, Specifically, as shown in FIG. 3A, a coating agent quantitatively measured according to the area of the surface of the glass 100 is wetted so as to flow along the surface of the glass 100, Or the oblique direction, the coating layer can be formed without a boundary surface of the coating surface as shown in FIG. 3 (b).

In addition, since the coating agent can be uniformly applied on the glass by wetting the coating agent on the roller and pressing the roller on the glass by rubbing the coating agent on the glass during the coating operation or construction, the thickness of the coating layer 200 can be adjusted, . In comparison with these coating methods, there are sponge coating methods, can spraying methods, and shedding methods. However, these methods are not capable of controlling the thickness of the coating material during the coating operation and are not uniform and quantifiable according to the thickness. impossible. On the other hand, in the coating method of the present invention in which a releasing agent is applied, a coating agent is coated on the coated surface or the surface of the coated surface by a stripper made of a visible light transmitting film having a thickness of 0.01 to 0.1 mm, (200) can be easily separated and peeled, thereby preventing glass damage by the coating layer.

As described above, the infrared and ultraviolet coating composition prepared according to the embodiment of the present invention can easily and quickly be applied to the glass surface of a wide or narrow area as a liquid, Can be formed.

 Hereinafter, components constituting the infrared ray and ultraviolet barrier coating composition shown in the examples of the present invention will be described as follows.

Cesium tungsten oxide

The infrared ray contained in the sunlight is reflected to the outdoor side or absorbed to the indoor side, and is 0.1 to 5% by weight based on the total coating composition. The cesium tungsten oxide can block the infrared rays in a very small amount or allow a part of the infrared heat to be absorbed through the glass. When the content is less than 0.1% by weight, the visible ray transmittance is increased but the infrared ray shielding performance may be weakened. When the content is more than 5% by weight, enhanced infrared ray shielding performance may be obtained, but visible light transmittance may be deteriorated .

Binder resin

The binder resin maintains the curing of the coating composition and the shape and adhesion of the coating layer. The binder resin accounts for 20 to 35% by weight of the total coating composition. The binder resin may further include any one or a mixture of two or more selected from the group consisting of an acrylic resin, an alkyd resin, an epoxy resin, a polyester resin, a vinyl resin, a rosin and a chlorinated rubber resin, Further, it is also possible to use at least one of dipentaerythritol hexaacrylate, pentaerythritol triacrylate, 1,6-hexanediol diacrylate, tripropylene glycol diacrylate, trimethylolpropane triacrylate, polyethylene glycol diacrylate, One or more materials selected from the group consisting of urethane acrylate, urethane acrylate, polyester acrylate, epoxy acrylate, melamine acrylate, N-vinyl pyrrolidone and silicone acrylate. When the content of the binder resin is less than 20% by weight, the adhesiveness is deteriorated and the visible light transmittance is improved. When the content of the binder resin is more than 35% by weight, the adhesive property is improved, but the visible light transmittance is lowered and the viscosity is increased, so that a uniform coating surface can not be obtained in the coating agent coating application and the binder resin can be peeled off after curing, It is preferable to control the content.

UV-rays Treatment agent

The ultraviolet rays contained in the sunlight are reflected to the outdoor side or partially absorbed to the indoor side, and it is 1 to 10% by weight based on the total coating composition. As the ultraviolet ray treatment agent, one or at least one of oxybenzone, benzophenone, and cinnamate may be used, or a hydroxyphenylbenzotriazole system may be used. Also, 2- (2H-benzotriazol-2-yl) -p-cresol) 2- (2H-benzotriazol-2-yl) -picresol as an ultraviolet ray treatment agent; 3- (3-tertiary-butyl-4-hydroxy-5- (5-chloro-2-tert-benzotriazol- -4-hydroxy-5- (5-chloro-2H-benzotriazol-2-yl) phenyl) propionate; And 2- (2-hydroxy-3-tert-butyl-5-methylphenyl) -5-chlorobenzotriazole. Or one or more selected from among them. When the content of the ultraviolet ray treatment agent is less than 1% by weight, the ultraviolet ray shielding performance is deteriorated. When the content of the ultraviolet ray treatment agent is more than 10% by weight, the ultraviolet ray shielding performance is improved, the visible ray transmittance is lowered, And then peeled off.

Ester solvent

The ester-based solvent is selected as a low-pollution incompatible solvent in consideration of the fact that the purpose of use of the coating composition is a glass coating, and is 20 to 35% by weight based on the total coating composition. As the ester-based solvent, it is preferable to use butyl acetate having a boiling point of 120 ° C. Butyl acetate having a boiling point of 120 ° C was selected as a non-pollution-imparting dispersing solvent because it was not deformed or altered by infrared ray penetration of high temperature. When the content of the ester-based solvent is less than 20% by weight, the incomparability is deteriorated and the adhesive property becomes too hard to be hardened. When the content is more than 35% by weight, the visible light transmittance is lowered and the adhesiveness is deteriorated. It can be peeled off and exhibits an incredibly strong fragrance dissipation property. Therefore, it is preferable to adjust the content of the ester solvent to be in the range of 20 to 35% by weight based on the total coating composition.

Organic solvent

The organic solvent is contained in an amount of 10 to 50% by weight based on the total coating composition. Preferred examples of the organic solvent are selected from 1-Methoxy-2-propyl acetate and ethylene glycol monobutyl ether acetate at a boiling point of about 100 ° C., And may further comprise any one or a mixture of two or more selected from the group consisting of carbonates, aromatic hydrocarbons, ketones, acetates, ethers, and alcohols. Typical examples thereof include IPA, xylene, and diethylene glycol monobutyl ether, diethyl ketone, methyl butyl ketone, dipropyl ketone, cyclohexanone, n-pentanol, Propylene glycol monomethyl ether, propylene glycol monoethyl ether, n-butyl acetate, amyl acetate, ethyl lactate, n-butyl lactate, n-butyl lactate, Methylcellosolve acetate, methylcellosolve acetate, ethylcellosolve acetate, propylene glycol monomethyl ether acetate, and ethyl-3-ethoxypropionate. If the content of the organic solvent is less than 10% by weight, the coating agent may become excessively hardened to lower the adhesiveness and the visible light transmittance is deteriorated. If it exceeds 50% by weight, the visible light transmittance is lowered, the adhesiveness is deteriorated, and it may be peeled off after curing.

Hereinafter, embodiments according to the present invention will be specifically described. The present invention is not limited to the embodiments.

The coating amount of the coating agent was quantitatively measured in the range of 20 to 30 g per 1 m 2 of the glass surface. Then, the metered coating agent was wetted on the application roller. Then, a coated surface was formed by rubbing the glass surface with the application roller, followed by drying and curing in the air to form a coating layer comprising an infrared ray and an ultraviolet barrier coating on the glass surface.

≪ Comparative Example 1 &

A general organic solvent was used without using the ester-based solvent used in Example 1. The coating composition was sprayed onto the glass surface by a can spray method to form a coating layer.

≪ Comparative Example 2 &

A general organic solvent was used instead of the butyl acetate used in Example 2. The coating composition was sprayed onto the glass surface by a can spray method to form a coating layer.

≪ Evaluation result >

The coating compositions prepared in Examples 1 to 3 were used as glass coatings to form coating layers. The coating layer formed in this manner did not show the toxicity of the odor after the application, and the coated surface was coated by a rubbing operation through the roller to form a coating layer having a uniform thickness and uniform distribution. However, in Comparative Examples 1 to 2 , It was evaluated that it was unsuitable as an indoor coating agent because of its strong odor and toxicity. Also, it was observed that the coating layer had a difference in thickness due to application of the can spray method and that the coated surface was not smooth.

The characteristics and physical properties of the coating layer formed by the coating agent prepared according to Examples 1 to 3 of the present invention and the coating method using the coating agent were evaluated in comparison with the clear type heat shielding coating film, Respectively.

Evaluation items Infrared / UV protection film (existing) Infrared / ultraviolet barrier coating layer (present invention) Durability 5-7 years 10 to 15 years or more Thermogenesis Wrinkles due to film deterioration No deformation at 80 ℃ or lower Optical distortion Distortion, distortion, eye fatigue No visible distortion Indoor reflections Indoor light reflection at night There is no room light reflection at night. Coated surface Joint occurrence There is no een hawk. Hardness L ~ 2H to L ~ 2H High hardness over 4H Construction Template glass construction impossible Template glass construction possible price The average construction cost of 1㎡ is 150,000 (KW) 1㎡ Construction price 100,000 (KW) Non-acidic There is no scattering. There is scattering. Evaluation results The coating layer of the present invention was relatively superior to the clear type film in each evaluation item except for the non-acidic property, and the coating layer formed by the present invention had a discolorable property and had no rejection due to odor after coating.

As can be seen from the above Table 1, the coating layer and the coating method using the coating composition prepared according to Examples 1 to 3 of the present invention are more important than the conventional coating films in terms of durability, heat distortion, economical efficiency, The use of ester based solvents and a limited amount of cesium tungsten oxide as cesium tungsten oxide as a small amount of infrared reflection and absorption processing agent are limited to use as an indoor glass coating agent, And it was evaluated that the coating method of the coating agent can be easily and easily applied because the uniform coating film can be completed by the rubbing operation through the roller. In addition, the infrared and ultraviolet ray shielding performance was excluded from the evaluation because it depends on the material used, the thickness of the coating layer, the thickness and the area of the glass, and can be compared in terms of general performance.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and substitutions, changes and modifications may be made by those skilled in the art in the technical field of the present invention.
