Abstract
In the present invention, a breakthrough invention deviated from the conventional technology that had to use a film adhesion method or a liquid paint when coating the color of the glass surface, specifically, by generating static electricity to adhere the powder coating to the surface of the glass The present invention proposes a color coating method for producing colored glass.
Description
The present invention relates to a method of coating a glass surface, and more particularly, to generate a static electricity on the surface of the glass to coat the powder coating to provide excellent durability even in high temperature and high humidity environment as well as to prevent environmental pollution. A method of coating color on a surface.
In general, color glass is expressed in various colors or patterns and is mainly used to create an aesthetic sense such as architectural lightweight interior materials or interior / exterior finishing materials. Such colored glass has been manufactured by attaching a film with a colored pattern printed on the surface of the transparent glass or by transferring it in a sheeting manner, or by producing a silkscreen printing method.
However, the manufacturing method of the color glass as described above has a number of problems, the method of attaching the film with the color pattern printed on the surface of the glass can be attached to the film only by applying heat at a high temperature of 700 ℃ or more. . Thus, when high temperature of 700 ℃ or higher is applied to the surface of the glass in order to attach the film, the plate glass is changed to tempered glass, and the glass changed into tempered glass becomes impossible to be cut and cut color glass at each construction site. There was a problem in that color glass cannot be used as a building interior material or decoration because it cannot.
In addition, since the ink used in the film attaching method must use an expensive ceramic-based paint or ink that can withstand high temperatures, it has been pointed out that the manufacturing cost of color glass is expensive and the color looks simple and cloudy.
In the case of the silkscreen printing method, when the same design is repeatedly printed, the same design cannot be printed in the same color, and thus, the same color pattern printed color glass cannot be produced in large quantities.
On the other hand, in addition to the above-mentioned techniques of coating the color on the surface of the glass is a method of coating a variety of colors by spraying a liquid paint, such as paint on the surface of the glass is used, specifically, to clean the surface of the glass Next, there is a method for manufacturing colored glass by spraying a liquid paint directly on the surface of the glass using a spray gun.
However, in the conventional color coating method as described above, the operator sprays the liquid paint directly on the surface of the glass by hand using a spray gun, which not only makes the working environment very poor but also causes the liquid paint to be scattered in all directions to contaminate the surrounding environment. There was a problem that the periphery of the workplace is dirty.
In addition, since the operator performs manual coating, the liquid paint sprayed on the surface of the glass is not evenly sprayed, which increases the defect rate of the product (color glass) and wastes the liquid paint and glass unnecessarily. There was a disadvantage that the quality of the glass was significantly lowered. In addition, by spraying a liquid paint on the surface of the glass to coat a variety of colors on the surface of the glass there was a problem causing environmental problems such as poisoning by the solvent or air pollution and fire.
An object of the present invention is to provide a method of coating a color on the glass surface to generate a static electricity on the surface of the glass to improve the clarity of the color by coating the powder coating and to improve the durability even in high temperature and high humidity conditions. .
In addition, an object of the present invention is to provide a method capable of uniformly coating various colors on the surface of the glass.
It is also an object of the present invention to provide a method of coating a color on a glass surface to prevent environmental pollution and to be able to work in a clean environment.
The present invention provides a method of coating various colors on the surface of a glass, the method comprising: washing the surface of the glass with isopropylene alcohol and air, and then applying a primer composed of an acryl sol, a hydrocarbon, and a curing agent thereon; A second step of applying color from outside to generate static electricity, applying static electricity to the surface of the glass which has passed the first step, and then spraying powder coating on the surface of the glass to coat the color; When the glass that has passed through the second step enters the drying furnace, the glass is cured by hot air at a holding temperature of 180 to 200 ° C. for about 10 to 15 minutes, and then reaches a stripping jig through the drying furnace to inject cooling air with an aerosol valve to slow cooling. It is characterized by the third step of forming colored glass.
In addition, the present invention is characterized in that the powder coating is uniformly coated on the surface of the glass and to apply static electricity generated by applying a voltage of 70 ~ 90KV to the surface of the glass in order to increase the adhesion.
In addition, the present invention is characterized by using a mixture of 2 to 7% by weight of glue powder and 93 to 98% by weight of powder coating in order to increase the strong adhesion and ductility of the powder coating.
The present invention, by coating a variety of colors on the surface of the glass using a powder coating to prevent environmental pollution, which is a problem caused by the use of liquid paint containing harmful substances, can always maintain a clean working environment, and also in a hot and humid climate Not only can maintain the original color as it is, there is an advantage that can form a coating layer of a uniform thickness.
In addition, the present invention can be free from the risk of addictive and fire by coating color on the surface of the glass using a powder coating rather than a liquid paint, environmentally friendly by solving the air and water pollution or pollution problems, and the quality of the color glass Excellent effect.
In addition, the present invention can obtain a high degree of corrosion resistance, chemical resistance, strong adhesion as well as to achieve a variety of color glass products of environmentally friendly materials by coating a powder surface of 100% solids without any solvent added to the glass surface There is an advantage.
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the following description will be presented a representative embodiment in the present invention to achieve the above technical problem. And other embodiments that can be presented with the present invention are replaced by the description in the configuration of the present invention.
In the present invention is a breakthrough invention deviated from the conventional technology that had to use a film adhesion method or a liquid paint when coating a color on the surface of the glass, specifically, by using a static electricity to adhere the powder coating to the surface of the glass To implement a color coating method that can produce colored glass of color.
To this end, a method of adhering the powder coating to the surface of the glass should be specifically disclosed. That is, since the powder coating is powdered powder, when sprayed onto the glass surface due to the characteristics of the product, the powder coating does not adhere to the glass surface, but flows naturally. A specific method of preventing and solving such a problem should be disclosed. And each pretreatment process and drying process required after coating the color on the surface of the glass should be specifically disclosed.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 is a view sequentially showing a method of coating a color on the surface of the glass according to an embodiment of the present invention. In the color coating method of the present invention, the surface of the glass is washed, and a pretreatment step of coating a primer → generating static electricity on the surface of the glass → coating a powder coating on the surface of the glass to which static electricity is applied → coated glass Drying step. Hereinafter, each step will be described in detail.
1. Pretreatment Step
Isopropylene alcohol is sprayed together on the surface of the glass while blowing air at a pressure of 7 kg / cm 2 (compressor: 50 hp) to remove foreign substances, and then the surface of the glass is coated with a primer. At this time, the primer is a mixture of 25 to 30 weight of the acryl sol 35 to 40 weight of the hydrocarbon and the remaining weight% of the curing agent.
2. Powder Coating Coating Step
The glass, which has undergone the pretreatment step, is subjected to a color coating step, in which static electricity is generated on the surface of the glass and then coated using powder coating. That is, when a voltage of 70 ~ 90KV is applied to the electrode plate provided on the back of the glass, static electricity is generated, and the static electricity is applied to the surface of the glass. In this case, when the powder coating is sprayed on the surface of the glass, the powder coating is adhered to the glass surface without being scattered by static electricity and coated in a uniform state.
Specifically, the static electricity generated in the electrode plate is applied to the surface of the glass, and when the powder coating is sprayed on it, the powder coating is adhered to the surface of the glass without being dispersed in the work space due to the static electricity generated throughout the glass Then, since the powder coating is no longer stuck to the glass surface due to the repulsive force of the static electricity, the powder coating is coated on the surface of the glass with a uniform and uniform thickness.
At this time, glue powder is added to the powder coating used in the present invention, so that the powder coating is well adhered to the glass surface to have a strong adhesion and ductility to the powder coating. Herein, the blending ratio of the powder coating and the glue is preferably 2 to 7% by weight of the powder coating and 93 to 98% by weight of the powder coating.
3. Drying Step
As described above, the powder coated glass is subjected to a drying process. Preferably, the glass coated with color is dried by hot air at a temperature of 180 to 200 ° C. for about 10 minutes, and then, through a drying furnace, to a stripping jig. Upon arrival, the colored glass of the present invention is completed by injecting cold air with an aerosol valve to slow cooling.
1 is a view showing a step of manufacturing a color glass by coating a powder coating on the surface of the glass according to an embodiment of the present invention.
