Description

Lacquering method and lacquer composition {Lacquering method and lacquer composition}

The present invention relates to a lacquer method and a lacquer composition, and more particularly, to a novel lacquer method and lacquer composition capable of exhibiting a three-dimensional texture.

Lacquer is the sap collected from the lacquer tree. For a long time, it has been widely used mainly in East Asia as a paint that forms a pollution-free coating film that is harmless to the human body for metal or woodwork painting, and for decoration or preservation of living utensils. The act of applying lacquer sap is also called lacquer.

When lacquer is applied to everyday items such as furniture, tableware, stationery, weapons, and buildings, it not only forms a solid and hard film on the surface, but also gives a subtle luster and does not change even after long use. Lacquer is recognized as a natural paint with excellent durability.

Compared to paints and enamels, lacquer has depth in gloss and color, enabling heavy artistic expression and excellent tactile feel. Because it has an elegant and beautiful color, it is also used for finishing arts and crafts and works of art.

Lacquer is a W/O emulsion, which is composed of 60-70% catechol structured fat molecules (eg urushiol), glycoproteins, polysaccharides, and 1-2% laccase enzyme.

Laccase enzyme and polysaccharide exist in the micro droplets trapped inside the lacquer liquid, and copper ions present in the laccase enzyme react with oxygen in the air to cause polymerization of fat molecules having a catechol structure to form a very dense network structure. It is known. Lacquer is a natural coating that does not require chemical additives.

In general, it is known that lacquer is uniformly applied to a substrate and polished to achieve a smooth finish. In this way, lacquer has been limited in terms of the color and texture expression method of lacquer by prioritizing the smooth surface treatment texture as a paint. Therefore, despite the many advantages of lacquer, its use range is being reduced in favor of paint or enamel synthetic paint. It is necessary to develop a lacquer method that can enhance aesthetics and diversity while maintaining the excellent properties of lacquer.

An object of the present invention is to provide a method of lacquer that can express a three-dimensional texture. In addition, an object of the present invention is to provide a lacquer composition capable of expressing a three-dimensional texture, and to provide an article manufactured by the lacquer method according to the present invention.

The problem to be solved by the present invention is not limited to the problem mentioned here, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

In order to solve the above problems, the present invention comprises the steps of i) trimming an object to be lacquered; ii) mixing lacquer and mammalian milk to control the coating; iii) applying the paint prepared in step ii) to the object trimmed in step i); and drying the article coated with the paint in step iii).

In addition, the present invention provides a lacquer method in which lacquer and mammalian milk are mixed in a ratio of 3: 7 to 7: 3, preferably 6: 4 in step ii), and the mammal in step ii) It provides a lacquering method in which milk is selected from the group consisting of milk, horse milk, sheep milk, and goat milk. The step (iv) may be dried at a humidity of 95% or more, a temperature of 18 to 28 ° C, preferably a humidity of 95% or more and a temperature of 25 to 27 ° C.

In addition, the present invention provides a lacquer composition in which lacquer and mammalian milk are blended, and provides an article coated with such a lacquer composition.

The lacquer method provided by the present invention is a paint in which both components are entangled with each other by mixing lacquer and mammalian milk, and drying in an over-humidity environment of 95% or more makes the surface of the article coated with the paint stand out and form a three-dimensional texture and various designs and patterns can be expressed, enabling the production of products with more individuality and improved aesthetics.

The new lacquering method of the present invention gives the effect of implementing a new paradigm of lacquer culture by enabling a modern design with a unique and new aesthetic effect by diversifying the design and surface texture of lacquered articles.

In addition, compared to existing lacquer products where there was a lot of concern about scratches where the surface is smooth and has a subtle gloss, the lacquer product according to the present invention is not easily scratched due to its three-dimensional texture, and even if it is fine, it is visible to the naked eye. It has a practical advantage for use in daily life because it is not marked.

Furthermore, the lacquered article by the lacquer method according to the present invention maintains the excellent properties of lacquer such as moisture proof, insect repellent, electromagnetic wave absorption, far-infrared radiation, etc., while improving the aesthetics and diversity according to the practice of the present invention as described above. It is possible to manufacture advanced items.

The effects of the present invention are not limited to these literal descriptions, but also include everything that a person skilled in the art can infer through the present invention.

Figure 4 is a photograph comparing the surface state before and after the drying process when producing a lacquered article by applying the lacquer method according to an embodiment of the present invention.

Hereinafter, the lacquering method according to the present invention, the lacquer composition, and the article produced by the method will be described in detail. Throughout this specification, unless otherwise specified, "include" or "include" refers to the inclusion of a certain component, and cannot be construed as excluding the addition of other components.

The inventor of the present invention recognized the need for diversification of the surface treatment method that can be expressed as lacquer and continued research on the physical properties of lacquer material. , the present invention was completed by revealing that a unique three-dimensional texture can be expressed by applying it to objects such as wood, metal, leather, canvas panel, etc. and drying it in an excessively humid environment.

Unlike general paints, such as paint, which dry when left at room temperature after painting, lacquer is dried only when appropriate drying conditions (temperature of about 24~28℃, humidity of about 70~75%) are met. Therefore, lacquer dryers designed to control the proper temperature and humidity after applying lacquer are used.

Lacquer drying is particularly sensitive to humidity. It is known that when a lacquer coating film is exposed to a humidity environment, water settles on the film to promote the reactivity of laccase, which is active in water, and to induce polymerization of fat molecules (eg urushiol) having a catechol structure. .

This polymerization reaction of lacquer may proceed for a long time from one day to several months depending on the components of the lacquer liquid and the reaction conditions. The lacquer coating film formed through the polymerization reaction exhibits excellent adhesion to various substrates such as wood, paper, and metal.

However, if the humidity is too high, the lacquer may be burned or crumpled and wrinkled, causing weeping or bleaching. Normally, 'good' lacquer should be the same before and after drying the lacquer, but the inventor of the present invention reversely applies this to dry lacquer in a fairly excessive humidity condition, not in an environment suitable for drying lacquer, It was found that new textures and aesthetic elements could be created on the surface.

This will be described in more detail through the drawings as follows.

1 shows a lacquer method according to the present invention, which includes: (i) trimming an object to be lacquered; (ii) mixing lacquer and mammalian milk to control the coating; (iii) applying the paint prepared in step (ii) to the object trimmed in step (i); and (iv) drying the article coated with the paint in step (iii) in an excessively humid environment.

The object to be lacquered in step (i) may be a wooden object, a canvas panel, metal, or leather.

In one embodiment according to the present invention, a method of trimming when the object is wood is as follows.

1) First, apply thin lacquer (raw lacquer) to the object and dry it. Through this, it is possible to kill insects remaining in the wood and give it hardness. When the epidermis of the lacquer tree is scratched, a grayish-white milky resin comes out, and impurities removed from it are called raw lacquer. Raw lacquer can be mixed with turpentine in an appropriate ratio, for example 1:1.

2) After polishing, attach the fabric with foil (a combination of lacquer and paste in an appropriate ratio, for example, a 1:1 ratio) and dry. It is desirable to spread the foil thinly, and the fabric may be hemp cloth or any cotton fabric.

3) After polishing, fill in the eyes with clay (a combination of lacquer + ocher + water, for example, 1 lacquer: 1 ocher + 1 water) and dry.

4) After polishing, evenly trim the surface with earthenware and dry it.

5) You can repeat 3) and 4) until the entire surface is even.

6) After polishing, you can apply raw lacquer and dry it to harden the previous ash work.

7) After diluting the black lacquer with terrapin oil to a level that is not too thick, paint it, dry it, and you can proceed about twice.

The lacquer used in the step of mixing the lacquer of step (ii) with the milk of a mammal to control the thickness of the paint can be any lacquer to be expressed, such as black lacquer or coloring. Mammal milk, horse milk, sheep milk, goat milk, etc. are possible, and cow's milk is preferable. Lacquer and mammalian milk may be mixed in a ratio of, for example, 3:7 to 7:3, preferably 6:4, depending on the desired ratio.

In the step of applying the paint prepared in step (ii) to the object trimmed in step (i) in step (iii), various tools such as brushes, brushes, spatulas, cotton, and hands can be used, and the desired texture, pattern and Any tool can be used as long as it can express a pattern.

The step (iv) of drying the article coated with the paint in step (iii) in an overhumid environment is, for example, a humidity of 95% or more, a temperature of 24 to 28 ° C, preferably 25 to 27 ° C, more preferably can be dried at about 27 ° C.

The present invention also provides an lacquer composition in which lacquer and mammalian milk are blended in one embodiment. The lacquer included in the lacquer composition may be any lacquer to be expressed, such as black lacquer, coloring, and the like. Mammal milk, horse milk, sheep milk, goat milk, etc. may be used, and cow's milk is preferred. Lacquer and mammalian milk may be mixed in a ratio of, for example, 3:7 to 7:3, preferably 6:4, depending on the desired ratio.

Lacquer can be produced in the following ways, for example. First, raw lacquer is collected from the lacquer tree. The lacquer liquid used is collected from the lacquer tree 5 to 6 years after planting from the beginning of June to the end of September.

Since the raw lacquer collected from the lacquer tree contains foreign substances such as branches, leaves, bark, and insects, a filtering process can be performed using a predetermined filter or press. The raw lacquer from which foreign substances are removed is put in a wooden or metal container and stirred at a temperature of 30 to 45 ° C. to uniformly disperse the components of the sap while evaporating moisture contained in the sap.

For example, the natural lacquer may be stirred for about 2 to 24 hours depending on the moisture content while maintaining the temperature at 30 to 45 ° C using an electric heater or an infrared heater to evaporate the moisture present in the natural lacquer solution. It is preferable to make the water content after evaporation of moisture to be 2 to 3%. Animal and vegetable drying oils, pigments, natural or synthetic extenders and the like may be added depending on the intended use.

Tablet lacquer may be prepared by the stirring and heating process as described above. By mixing drying oil such as perilla oil, flax oil, and paulownia oil with the refined lacquer, the gloss and workability of the lacquer paint can be improved.

The present invention also provides an article coated with a paint by the lacquer method. The article may be any article suitable for the purpose, such as daily necessities such as furniture, tableware, stationery, weapons, and buildings.

Those skilled in the art will understand that the above-described lacquer method, lacquer composition, and lacquered article are merely examples, and various changes and modifications are possible without departing from the technical spirit of the present invention.
