Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for manufacturing a metal panel using natural lacquer coating,

The present invention relates to a method for producing a natural enzyme-purified metal panel through lacquer coating. More specifically, the primer is applied as a pretreatment, UV printing is applied, and then the rust lacquer is applied as a post-treatment to enhance the expression of the pattern printing layer, improve the adhesion of the panel and pattern print layer, To prevent peeling of the pattern printing layer and to remove the color of the lacquer coating and make it transparent so that the color is not changed even after the lapse of time after the formation of the lacquer coating layer, , A natural enzyme-refined metal panel with lacquer coating that can realize ceiling materials with environmentally friendly and nonflammable functions by combining the lacquer with the lacquer having the atopy treatment effect, antiseptic, antibacterial, deodorant, preservative effect, insecticide, And a method for producing the same.

Currently, Korea imports most indoor decorations such as tiles and ceilings in USA and Italy. The domestic tile market is about 100 million square meters, but domestic producers occupy about 38 million square meters. The share of imported tiles increased to about 59% in 2008.

In Korea, ceiling materials that focus on functionality such as sound absorption, sound insulation, and sound insulation, which can be used in homes, offices, libraries, etc., are on the market. These ceiling materials are mostly used to produce harsh effects by perforating the product, but they are used only as a simple ceiling finishing material, except for functionality, which focuses on functionality only.

As such simple ceiling finishes, there is a lack of special technical and design features such as products that express color by coloring, products designed by expressing pattern, and products that absorb sound by perforation. Giving.

Gypsum - based ceiling materials in the existing ceiling materials market have no design elements as well as the risk of asbestos, they are easy to break down and are vulnerable to moisture, which limits their use.

As compared to wallpaper and tile, gypsum - based ceiling materials occupy the majority of market. However, the risk of asbestos has risen and the use of asbestos ceiling materials is gradually decreasing. Since the use of asbestos products has been fully regulated since 2009, most existing ceilings containing asbestos must be replaced, necessitating ceiling materials to replace asbestos ceilings.

Recently, as the well-being and quality of life have been raised, consumers are paying more attention to the interior, and even though the price is rather expensive, focusing on using luxurious materials, There is a need to develop a design ceiling material that adopts an environmentally friendly method.

A related art is disclosed in Korean Utility Model Registration No. 0414347 (Apr. 20, 2006), which discloses a technique of forming a stone sprue layer on the top surface of a flame retardant nonwoven fabric layer to give a three-dimensional feeling and a high strength and a flame retarding effect. The prior art relates to a flame retardant nonwoven fabric layer formed at the lower end of the flame retardant nonwoven fabric layer and a built-in built-in panel formed of a stone foam material layer forming a layer at the upper end of the flame retardant nonwoven fabric layer, There is a limitation that it is difficult to form an appearance that is likely to be durable and poor in design.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the preferred embodiments of the present invention will be described below, but it is needless to say that the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.

FIG. 1 is a process diagram of a method for manufacturing a natural enzyme purified metal panel through lacquer coating according to a preferred embodiment of the present invention, and FIG. 2 is a view illustrating a method of preparing a natural enzyme purified metal panel by lacquer coating according to a preferred embodiment of the present invention Fig. As the metal panel, a variety of panels including a ceiling panel can be applied. Hereinafter, a ceiling panel will be described as an example.

2, a ceiling panel 10, a primer coating layer 20, a UV printing layer 30, and a lacquer coating layer 40 (see FIG. 2) ).

First, a ceiling panel 10 is prepared, and a primer coating layer 20 is formed by applying a primer to the ceiling panel 10 to increase the adhesion of the UV print.

As the primer, an urethane-based monomer in an organic solvent and an additive synthesized can be used. Examples of additives include plasticizers, flame retardants, antioxidants, stabilizers, wetting agents, dispersants and the like, and the kind of additives is not limited thereto.

The primer coating layer 20 serves to improve adhesion between the ceiling panel 10, which is a thermosetting resin, and the UV print.

Next, UV printing is performed on the primer application layer 20, and UV curing and thermal drying are performed to form the UV printing layer 30. For example, it is possible to produce a photographic image and gradation through UV printing. When the UV printing layer 30 is formed on the primer coating layer 20, the printing quality is improved and the peeling of the printed product is prevented. Unlike the screen printing method, unlike the screen printing method, the present invention uses a printing method using environmentally friendly UV inks. The UV printing method is free from environmental pollution in a printing process and can combine desired color quality with a small amount of ink. Excellent spreadability.

Next, the lacquer coating is applied on the UV printing layer 30 and dried to form the lacquer coating layer 40.

The lacquer has been used for tableware, raising and the like since ancient times, and the lacquer ware using lacquer refined in tombs was discovered during the Tripitaka Koreana and the first and second centuries BC. Lacquer is collected in Korea, China, Japan, Myanmar and Vietnam. However, it is known that the quality of lacquer is the most excellent in Korea.

As the lacquer coating, a transparent lacquer coating in which the color is removed is preferable. Conventional lacquer paints are transparent in their initial color but tend to discolor to dark brown color with time.

In the present invention, the color of the lacquer coating is removed and made transparent so that the color is not changed even after the lacquer coating layer 40 is formed.

Lacquer coatings can be prepared by purifying urushiol. The mixture of natural lacquer and acetone is well mixed and filtered with a filter. The precipitate filtered through the filter is washed with acetone, and the filtrate is concentrated by evaporation in a rotary evaporator under reduced pressure to purify urushiol.

Examples of compositions for urushiol coatings are as follows.

1 to 20 g of urushiol condensate, 1 to 30 g of urethane acrylate oligomer and 1 to 50 g of toluene were completely dissolved by stirring for 10 minutes, 0 to 20 g of photoinitiator was added, and the mixture was stirred at 30 to 80 ° C. for 1 to 5 hours to obtain acryl A lacquer coating solution is prepared.

Examples of the photoinitiator include acetophenone compounds, benzophenone compounds, halogen compounds, carbonyl compounds, dicarbonyl compounds, benzoin ether compounds, aminocarbonyl compounds, organic peroxides, diphenyl halonium salts, aromatic ketones, tertiary amines, Based compounds, thiol compounds, halogenated compounds, northern cyclic compounds, polycyclic compounds, bisamidazole compounds, N-arylglycidyl compounds, acridine compounds, peroxiketanes, azo compounds, iron- Or a titanocene compound may be used, and the kind of the photoinitiator is not limited thereto.

It was confirmed that the color of the UV printing layer 20 printed on the ceiling panel 10 was maintained even after a lapse of a considerable period of time after the formation of the lacquer coating layer 40 with the thus prepared lacquer coating .

In addition, it is easily discolored by applying the existing paint to acidic vinegar. However, the product painted with lacquer is not discolored even after 5 days, does not corrode strong alkali and salt, It has been confirmed that it is excellent in salt resistance, insolubility, insulation effect and excellent chemical preservation effect.

Due to the recent consumption of petroleum energy resources and the seriousness of environmental pollution due to the production of chemical paints, there is a growing interest in natural lacquer, especially unlike chemical paints, Respectively.

Among commonly used paints, varnishes have a melting point of 100 degrees, oil-based paints have a degree of 150 degrees, water-based paints have a degree of 190 degrees, cashews have a degree of 250 degrees, but lacquer paints have a thermal change at 400 degrees Which is excellent in heat resistance.

Since the lacquer paint has high moisture retention and low thermal conductivity, it is not easily heated and is suitable as a nonflammable paint.

In addition, applying lacquer has various effects such as atopy treatment effect, preservation, antibacterial, far infrared ray 90% or more release, deodorization and preservative effect. The present invention realizes a ceiling material having an eco-friendliness and a nonflammable function by combining the lacquer having the anticorrosion property, the antibacterial property, the insecticide property, the insulation property and the incombustibility with the ceiling material.

On the other hand, lacquer varnish does not rot after a long period of time because it acts as a preservative, and the original color of the tree is yellow, and the color of the tree does not change even after time passes. The lacquer tree protects human cells to prevent aging, acts as an insecticide, and is suitable for deodorization. It can be applied to ceiling panels used in the interior to extend the service life of the products and improve the residential environment.

In addition, there is no environmental hormones and chemical hormones, and it prevents decay. Lacquer has antibacterial effect of 100% against Staphylococcus aureus, Escherichia coli, Salmonella, etc., so that waterproof property and moisture resistance after lacquer is improved.

When a paint is applied to a conventional panel by a screen printing method or when a method such as the attachment of a film is applied, the design pattern drawn on the surface is not clear, which causes problems such as aesthetic feeling and visibility, There arises a problem from the viewpoint of durability that the design pattern of the surface produced by the attachment is lost.

In the present invention, primer, UV printing, and lacquer paint coating were performed so that the design pattern of the surface can be durably maintained on the panel body despite external stimulation or time lapse.

By using ultraviolet curable UV ink for design pattern printing, solvent ink which is a volatile organic solvent can prevent environmental harm, and it is excellent in durability compared to conventional ceiling materials such as a tex and gypsum board, This will reduce industrial waste. In the case of UV printing technology, since the curing is completed instantaneously during the printing process, the manufacturing process time is shortened to about 50%, and electric energy of about 30% can be saved.

As a result of trying the UV printing process on the panel which is used in the market without applying the primer and the lacquer coating, the appearance of the product appeared, but it was confirmed that the level of technology was considerably lowered in terms of durability and perfection. Specifically, the surface is exposed to scratches or impacts from the outside, so that the printed pattern layer is not protected against minor physical impacts.

In the present invention, by applying a primer by pretreatment and applying a lacquer coating by post-treatment, it increases the expression power of the pattern printing layer, improves the adhesion of the panel and the pattern printing layer, improves the durability by reducing the work defect rate, Peeling could be prevented.

It will be apparent to those skilled in the art that various modifications, substitutions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. will be. Therefore, the embodiments disclosed in the present invention and the accompanying drawings are intended to illustrate and not to limit the technical spirit of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments and the accompanying drawings .
