Description

Loess interior materials using japanning and process according to lacquer

The present invention relates to an ocher interior and exterior materials using lacquer, and more specifically, to an interior and exterior materials (brick, tile, pottery, etc.) using a natural adhesive mixture using ocher or ocher and grains, by lacquer which is an environmentally friendly paint, which is a natural material The present invention relates to a method for manufacturing ocher interior and exterior materials using lacquer, which can effectively improve the problems of cracking, surface abrasion, and contamination caused by chemical polishes, while maintaining the function and efficacy of the loess.

In general, ocher covers about 10% of the earth's surface, so the material is infinite, and it contains a large amount of calcium carbonate (CaCO ₃ ), which has a viscous power that is not easily broken.

In addition, loess is composed of various enzymes called living organisms. There are about 200 to 250 million microorganisms and about 1,300 different enzymes in a spoonful of yellow soil, and the enzymes perform toxin removal, degradability, fertilizer element, and purification.

In addition, the ocher is composed of a honeycomb structure with a wide surface to form a multi-layer structure consisting of a number of spaces, in the micropores of the loess is absorbed / stored a large amount of far infrared rays necessary for the growth of plants and animals. These far infrared rays are radiated when heated to stimulate molecular activity of other objects.

However, despite these advantages, ocher-based products have various problems in production / manufacturing.

For example, when the raw soil is manufactured as a product, there is a problem that the finished product is cracked or broken when the climate is dry due to low durability and impact resistance. In addition, in a high humidity environment, the surface of the product may recede, which causes the surface ocher to be buried outside and contaminate the surroundings.

In order to solve the problems of the durability and impact resistance of such ocher products, the ocher products were produced in ceramics, stone materials, and magnetic materials through a firing process, and then chemical paints such as glazes and pigments were added and mixed on the surfaces thereof.

However, in the case of the manufactured ocher products, when heat is applied in daily life, substances harmful to the human body are generated through chemical reactions, which contaminates the product so that it is difficult to expect the original eco-friendly function and efficacy of the ocher. It lowers the commercial value of the product.

Meanwhile, lacquer is an eco-friendly paint that is harmless to the human body extracted from lacquer trees, and is used for medicinal and edible foods. It is a high-quality coating material used in various fields such as furniture, furniture, and lacquerware as well as arts and crafts.

The lacquer is a traditional paint technique that has been produced a lot in some parts of East Asia, such as Korea, China, Japan, Taiwan, the touch of the film is good, has a calm luster and excellent transparency.

In addition, the lacquer has excellent antiseptic effect and bactericidal power and does not easily form mold even after a long time, and also has excellent properties of acid resistance, flame resistance, heat resistance, water resistance, nonflammability, and insulation.

As an example of a novel product to which the properties of lacquer are applied, Patent No. 744789 proposed by the inventors of the present application and the like, "a method of manufacturing lacquered wooden board material capable of expressing natural patterns and colors" are mentioned.

The present invention has been made to solve the above problems, by improving the existing ocher products modernly and lacquer on one side, while maintaining the function and efficacy of the natural loess as it is, the impact resistance is weak and easy to wear The main object of the present invention is to provide a method for manufacturing ocher interior and exterior materials using lacquer, which has been reinforced with exposed surfaces of molded ocher products.

Another object of the present invention is to prevent the contamination of the ocher molded body by the existing chemical paints, and to use all of the advantages of lacquer adhesiveness, gloss and touch, etc. It is to provide a method for manufacturing ocher interior and exterior materials.

Still another object of the present invention is to provide a method for manufacturing ocher interior and exterior materials using lacquer, which can be used as interior and exterior materials for high-grade construction by improving the aesthetics of the ocher product surface.

In order to effectively achieve the above object, the present invention, in the brick, tile, pottery interior and exterior materials made of loess, the interior and exterior materials are molded using a loess and a loess mixture kneaded natural adhesive using grains; The surface of the molded ocher mixture molded body is characterized in that the lacquer to form a lacquer film.

According to another aspect, the ocher mixture is characterized in that composed of 55 to 85% by weight ocher and 15 to 45% by weight of the natural adhesive using grains.

According to another aspect, the lacquer, the first coating is composed of 30 to 70% by weight of at least one of ocher and stone powder, and 70 to 30% by weight of lacquer; A second film composed of 65 to 95% by weight of lacquer and 35 to 5% by weight of a natural adhesive using grains; Characterized in that the coatings are repeatedly coated alternatively or in overlap.

In addition, the ocher mixture is characterized in that the fiber extracted from the natural plant is mixed therein as a durability enhancer.

According to another aspect, the fiber is characterized in that at least one of hemp, cotton, straw, reeds, sesame root.

According to another aspect, the ocher mixture molded body is characterized in that at least one of the fibrous pulverized particles extracted from the nonwoven fabric, Hanji, decorative sheet or natural plant is selectively compressed on the surface.

According to the present invention, by applying a natural paint lacquer to the natural material ocher, while maintaining the function and efficacy of ocher pollution, anion generation, far-infrared radiation, detoxification, deodorant, antibacterial, etc., the impact resistance is weak and wear The surface of the easy ocher molded body has the advantage that the durability and impact resistance of the ocher molded body is improved by strengthening the coating film of the lacquer to form a solid polymer coating film having a three-dimensional structure by the enzymatic reaction.

In addition, the ocher mixture molded body is mixed with fibers extracted from natural plants to improve the durability of the ocher together with lacquer.

In addition, the ocher molded body can be obtained by pressing the hanji or fiber crushed particles selectively on the surface of the lacquered molded body with the gloss and feel of the lacquer through the fiber crushed particles extracted from the hanji or natural plants.

Therefore, the ocher interior and exterior materials using the lacquer of the present invention is visually beautiful, and also excellent in chemical resistance, water resistance, heat resistance, chemical resistance, stain resistance, and rust resistance against acids, alkalis, salts, alcohols, etc., to maintain excellent durability. It can be produced in various forms such as eco-friendly high-grade buildings, interior and exterior and crafts, so that it is possible to obtain the effect of improving the value and commerciality of ocher products.

Hereinafter, preferred embodiments of the present invention will be described in detail.

The loess interior and exterior materials according to the present invention are products such as bricks, tiles, and pottery made of loess, which are first made of natural loess, or natural harmless to the human body made from grains such as wheat and glutinous rice to enhance the binding force of loess and loess. Prepare the ocher mixture by kneading the adhesive together.

Then, the prepared ocher or ocher mixture is subjected to a molding process to produce products such as bricks, tiles, and pottery having different specifications and shapes through high-pressure extrusion or conventional manual work.

That is, the natural ocher may be manufactured only, but in this case, the tensile strength and the compressive strength of the ocher are weak, so that the product may be easily cracked or broken after molding.

At this time, the effective mixing ratio of the loess and the adhesive of the ocher mixture is 55 to 85% by weight of loess, in which the binding force of the loess is optimized in consideration of the particle size of the ocher or the type of the adhesive, and 45 to 15% by weight of the natural adhesive using grains. It is preferable to configure by mixing%.

After that, in the case of bricks, the oxidized salt is fired at a temperature of 700 to 1100 ° C., but in the present invention, the molded ocher mixture molded body has a magnetic quality of 1200-1350 ° C., 1100, depending on the intended use (in consideration of color, weight, and thickness) Baking is performed by dividing it into stone material of -1300 ℃ and ceramic material around 1200 ℃.

Thereafter, the moisture contained in the fired product is removed and dried without cracks or deformations. Then, natural colored pigments are added to the purified lacquer or purified lacquer made by refining raw lacquer and purified lacquer on the surface of the dried ocher mixture. Lacquer is applied using a lacquer made of mixed color lacquer to coat the lacquer film.

The lacquer coating used for the lacquer coating is generally divided into a first coating used for forming a rough coating and a second coating used for the purpose of maintaining a smooth surface, and these are selectively used in consideration of properties of a desired product.

In the case of forming a lacquer coating on the ocher mixture molded body using the first paint and the second paint, the order of use and the number of repetition of the coating of the first paint and the second paint may be adjusted according to the quality of the product. .

In other words, the first paint first and then the second paint, or the second paint and then the first paint on it, and then look at the quality of the product and repeat the above process, or both You can select only one of them and paint them over and over again.

Such a first coating is produced by mixing the relative ratio of loess, stone powder or a mixture thereof and lacquer at a ratio of usually 1: 1.

The ocher is a material having an average particle size of 0.02 mm to 0.05 mm having fine pores, and the content of lacquer used according to the particle size is different from the smoothness of the surface after coating. In other words, when a large amount of loess is used, the amount of lacquer filled with the voids is also relatively increased.

Therefore, it is good to mix the finely ground stone powder to maintain the proper amount of lacquer. At this time, the stone powder is preferably to maintain the particle size, such as ocher. This increases the durability and lowers the rate of loess, which is beneficial for controlling the impregnation of lacquer.

In other words, if the mixture of ocher and stone powder is properly adjusted, the amount of lacquer can be reduced to a minimum, and the cost can be reduced, and the roughness of the surface according to the type of products produced on the surface of ocher products can be reduced. It is possible to form a controlled lacquer film.

At this time, the appropriate mixing ratio of the above-mentioned ocher, stone powder or a mixture thereof, and lacquer is considered to be the type of ocher and lacquer, the surface state of the product, etc. It is preferable to comprise 70-30 weight%.

And, the second coating, unlike the first coating is to maintain the shape of a smooth coating that does not have particles protruding to the surface.

This is provided to provide durability, impact resistance and fouling resistance of the surface of the ocher interior and exterior materials, and to control not only basic colors but also colors that are difficult to be expressed only by ocher according to the moisture content of lacquer added to the second coating. It is used for the purpose of such as, it will be used by mixing the adhesive using natural grains such as wheat or glutinous rice.

At this time, the mixing ratio of the lacquer 65 to 95% by weight relative to 35 to 5% by weight of the adhesive using natural grains is preferred.

On the other hand, the surface of the ocher mixture molded body can be pressed and pasted with a decorative layer such as Hanji, nonwoven fabric or decorative sheet to improve the aesthetics, and in particular, Hanji adds its own texture and beautiful pattern to the surface of the ocher molding to be used as a new interior material. To make it possible.

At this time, the decorative layer such as Hanji is stably bonded to the surface of the ocher mixture by the first paint or the second paint applied on the ocher mixture. To this end, it is required to attach a decorative layer such as Hanji before the first or second paint is dried, which is bidirectionally adsorbed into the decorative layer such as the ocher mixture molded body and the Hanji, and as a binder. This is to enable the function.

However, if the decorative layer such as the hanji exceeds a certain thickness, the suction amount is insignificant, so that a stable bond cannot be maintained, so that a first paint or a second paint is selectively added to the surface of the decorative layer such as the hanji. It is preferable to apply a to a stable bond without impairing the decorativeness of the surface.

In addition, the decorative layer functions as an auxiliary binding material of the loess and serves to enhance the durability and impact resistance of the loess.

In other words, if the lacquer is re-coated on the surface of the ocher mixture compact in which the hanji or the nonwoven fabric is compressed, the hanji or nonwoven fabric can be more firmly attached to the surface of the ocher molded body without being detached while exhibiting its texture. Will be.

As such, the ocher molded body as an interior and exterior material using lacquer is bonded to the human body such as hemp, cotton, straw, reed, root root roots to bind cracked loess and strengthen durability to prevent cracking or external cracking after production. Fibers extracted from harmless natural plants are further mixed into the loess mixture.

On the other hand, the fiber extracted from the natural plant may be made of crushed particles and pressed to the surface of the ocher molded body using a paste or paste. In this case, it has the effect of maintaining the surface texture as in the case of the previous hanji, non-woven fabric or decorative sheet.

In addition, all of the above processes can be appropriately sanded according to the state of the material of the ocher molded body and the state of the painted lacquer in order to improve the quality of the surface after the work is completed.

The present invention has been described in the case of applying to the interior and exterior materials as a specific embodiment, but is not necessarily limited thereto, the same effect can be expected even when applied to household ceramics such as tableware or ceramics, and the technical spirit of the present invention Of course, modifications and variations can be made within the scope.
