Wood is an essential material for construction and is a widely used material for construction of buildings, furniture and appliances. However, due to the nature of the material, there is a disadvantage that the damage by humidity, microorganisms or various insects are very vulnerable.

Antimicrobial, deodorant, and insect repellent treatments for wood processing include arsenic (As), varnishing, water-soluble inorganic salts such as phosphates such as ammonium phosphate and sodium phosphate or sulfates such as ammonium sulfate and sodium sulfate, and borax or boric acid. Has been used. These water-soluble inorganic salts have excellent effects, but when applied to these general woods, the calcium carbonate of the powder contained in cerebral green, etc. reacts for a long time to turn into calcium sulfate or calcium phosphate, causing whitening phenomenon. It not only impaired the effect but also resulted in lowering the effect.

Until now, synthetic resin-based materials have been widely used as a building material for the wood part of building interior materials. Such synthetic resin-based materials have a beautiful surface appearance as a patterned overlaid surface treatment, but the internal materials have become a problem due to harmfulness, and defects occur in the adhesive part over time, and there are various problems such as fading.

In particular, molding, one of the representative building interiors, uses MDF building E-2 grade, which is called as replacement wood. This MDF is manufactured by bonding to pulp or finely crushed wood powder, which causes severe sick house syndrome and building syndrome after form construction, which poses a health hazard such as formaldehyde, VOC and benzene.

In addition, most molding manufacturing methods use PVC lapping precision bonding on plywood to materials such as MDF building materials, PVC, PP, PS, styrofoam, etc. A high molecular compound obtained by a hybrid polymerization containing 50% or more of the compound, which is used for hard pipes, plates, molded articles, and synthetic fibers.

These building materials cause not only harmful substances such as VOCs, but also environmental hormones called Endocrine Disruptors. This substance is a chemical produced and released from objects in residential living spaces. When absorbed into living organisms, endocrine disruptors or endocrine disruptors are detected that interfere with or disrupt the normal functioning of the endocrine system. Dioxins can cause environmental disturbances.

Meanwhile, Korean buildings have been used as soil and wood as materials. This wood is suitable as a building material because of its excellent strength, flex resistance, and durability.However, the wood is strong and the surface of the material is rough and cracks occur during drying. Has come.

White clay, red soil, and yellow soil, which have been transmitted since ancient times, are known to be beneficial to the human body due to the generation of far-infrared rays and the self-cleaning effect of the soil. I prefer a lot. However, in buildings such as general homes, even if the soil is used on the wall, there are problems of cracking and environment-friendly treatment, which are difficult to select.

In addition, the well-being of the building materials using bamboo sap, phytoncide, etc. used in oriental medicine is known to be beneficial in many ways to the human body. However, like red soil and loess, it is difficult to use these materials as building interior materials, and it is difficult to put them into practical use because there are many difficulties in adding hazardous materials to the treated surface even if used as building interior materials. There was a problem.

The colored layer includes one selected from the group consisting of shell, elvan, chalcedony, red clay, loess, white clay, green tea leaf, coffee powder, spinach powder, paprika oil, mugwort powder, graphite, charcoal, and mixtures thereof. The colored layer is colored on the surface of the wood board, including natural materials, which are naturally friendly, to maintain the naturalness and beauty of the wood grain, it is possible to produce a product suitable for the consumer's taste by using the composition alone or mixed.

Representatively, the shell is the salt is removed to improve the antibacterial, anti-fungal, bactericidal and deodorant, beautifully by giving a unique color to the surface of the building interior materials. These shells may be divided into upper, upper, and nacre layers of the outer skin of the shell, and the inner layer of the pericardial layer, such as fine powder, plate or amorphous.

The elvan has an average particle diameter of 325 mesh, which is better for maintaining smoothness of the coating surface when the coating material and the interior of the mixed building are coated.

Also, ocher emits bio far infrared and anion, which is beneficial to human body, which is good for health and at the same time, it is excellent in warmth and breathability, can properly control temperature and humidity in the building, absorbs odors and detoxifies. This strong, intense stress buildup has the effect of releasing and calming the liver's crying and burning. In addition, the clay and loess has a sufficient strength to act to improve the strength of the building.

The colored layer can express various colors according to its composition. For example, using ocher, yellow, white clay, white, green tea leaf or spinach powder green, coffee powder brown, charcoal black. Various colors can be realized by using them properly.

The coating layer is formed on the coloring layer, and includes one selected from the group consisting of rare earth anionic agents, zeolites, phytoncide, titanium dioxide, hinokithiol, sulfisomidine, polyphenols, terpenes, and mixtures thereof.

Hinokithiol, which is one of the components contained in the coating layer, is obtained from natural materials, and has an advantage of very excellent antimicrobial properties. Also sulfisomidine is one of the aggressive antimicrobial agents, polyphenols and terpenes are vegetable essential oils, which are also known to be antimicrobial and antifungal.

The materials are also an eco-friendly natural material is released anion far infrared rays can not only use the texture of the wood as it is, but can also obtain the far infrared effect emitted from the natural materials. In addition, by using the composition to withstand the fungus, and to maintain the antimicrobial properties, there is an effect of preventing the decay, insect formation using antibacterial materials without applying formalin to natural wood as in the prior art.

Furthermore, when the surface is coated with natural materials such as bamboo sap and phytoncide to form a small film and dried, the natural color and pattern of the wood remain intact, and the pure functional antibacterial action (Methanol Staphylococcus aureus, Gil) Antibacterial action against the first bacterium, and the disintegration of fish periic acid to sterilize against Staphylococcus aureus) well-being building material.

The coating layer is formed thereon a nano-coating layer comprising one selected from the group consisting of silver nano and flavor capsules, and mixtures thereof.

These specific compositions and contents are not limited in the present invention, and can be appropriately adjusted by those skilled in the art, and are not specifically mentioned herein.

For example, in the case of using ocher to form the colored layer, the adhesion is excellent even when using only water without a separate binder due to the viscosity of the ocher itself. Used as a binder. As the binder, 15% of the natural mulberry sap and the mulberry were marinated in lukewarm for 48 hours, and then the adhesive sap was taken to mix the two substances.

According to a preferred embodiment of the present invention, the colored layer is 10 to 50% by weight of the shell having an average particle diameter of 300 mesh or more in the entire color layer composition, 15 to 40% by weight of clay having an average particle diameter of 300 mesh or more, elvan powder 5-20 Wt%, the coating layer comprises 2-3% by weight of the earth-based anionic agent in the total coating layer composition, 1-5% by weight of zeolite, 1-5% by weight of titanium dioxide, 0.6-1.0% by weight of hinokithiol, sulfisomidine 2.0 to 3.0 wt%, polyphenol 2.0 to 3.0 wt%, terpene 0.5 to 1.0 wt%, and silicate-based liquid binder 30 to 40 wt%, wherein the nano coating layer comprises 0.5 to 2.0 wt% of silver nano in the total nano coating layer composition and Flavor capsules from 0.5 to 2.0% by weight.

In this case, the balance may be water or various additives.

Hereinafter, a manufacturing method of a building material according to the present invention will be described with reference to the drawings.

First, the surface of the prepared solid wood plate of Figure 1 is subjected to sanding or sanding process, as shown in Figure 2 to give the surface of the solid wood plate as irregularities with a depth of 0.5 ~ 2 mm.

When the sanding or sanding process is finished with a brush bound with a thin wire of 1 mm in diameter, the thin and soft parts are trimmed and the strong and hard parts are not cut or only slightly cut, leaving only the hard part of the wood. At this time, if too strong sandpaper treatment, the appearance of a large digging phenomenon and a long drying time should be less than 2 mm due to poor workability. On the contrary, if the thickness is less than 1 mm, the coagulation force is weak during the sanding process, so the product defects are many and the sandpaper treatment standard must be selected.

For example, when a tree grows, it grows with the intersection of hard and soft parts depending on the season. That is, the ring formed in the winter is hard, and the ring formed in the summer is wide and soft, so the sandpaper treatment standard is selected in consideration of this.

In this way, the wood plate sandpaper treated is left with a strong part of the ring, the weak part is removed by sandpaper treatment (see Fig. 3). As a result, the sandpaper-treated wood plate is formed with a fine protrusion like a downy, and when viewed from the side of the plate side, the protruding parts are arranged like many geese side by side with the wings, and the small tree hairs are jagged. It does not undergo any deformation even after application or coating of various compositions in subsequent processes, and does not drop over time, so that the components contained in the coating composition, for example, functional components such as anions, are continuously maintained and discharged, and after construction or time elapsed. Later there will be no defects.

Next, to form a colored layer by coating the composition for the colored layer on the surface of the solid wood plate formed with the irregularities.

The composition for the colored layer comprises one selected from the group consisting of shells, elvan, chalcedony, red clay, ocher, white clay, green tea leaves, coffee powder, spinach powder, paprika oil, mugwort powder, graphite, charcoal, and mixtures thereof. It is used by dispersing in various solvents so as to have an appropriate viscosity.

The colored layer composition is coated on the surface of the solid wood plate using a pressure sprayer and then dried at 40 to 60 ° C. for 24 to 72 hours. At this time, the coating is performed several times to adjust the thickness of the colored layer.

The coating is carried out by a conventional wet coating method, it is preferable that the coating is strongly applied using an air gun for application and a compressor. At this time, the colored layer is formed in the thickness of 0.1 ~ 2 mm on the surface of the solid wood plate for color expression.

Figure 4 shows a solid wood plate colored in clay, Figure 5 is ocher, Figure 6 shows a solid wood plate painted green tea leaves and red soil.

Next, coating the composition for the coating layer on the colored layer to form a coating layer.

It is generally colorless or white translucent, and includes the following types: palestone, fisheye, cabbage, soda-stone, hydrandite, steel bite, lomontite, and incinite. Since the zeolite has a loose crystal structure and bonds with each atom at high heat, the zeolite can be used to adsorb other particulate matter since the skeleton remains the same.

Titanium Dioxide is a colorless or white powder with no odor and taste and exhibits a photocatalytic effect.

Hinokitiol is a tropolone substituent and is known to have a seven-membered ring that is aromatic in its molecule. It is present in essential oils such as juniper. The hinokithiol is also referred to as β-tuyaplicin and 4-isopropyltropolone, and is present in essential oils such as cypresses and juniper, such as Taiwan cypress and Nahanbaek.

Sulfisomidine is widely used for the treatment of bacterial diseases due to its high antibacterial properties, fast absorption and excretion.

In addition, polyphenol is a representative polyphenol compound of catechins in green tea, and the antioxidant function of this substance is well known, and thus it is applied to food or medical care. In particular, catechins in green tea, chlorogenic acids in coffee, strawberries and eggplants, grapes, black beans, red and purple anthocyanin-based pigments are all polyphenolic compounds. In addition, polyphenol compounds are included in various kinds of vegetables, fruits, cacao and red wine. Such polyphenols have an action of preventing oxidation, that is, an antioxidant function. The reason why polyphenols are attracting attention recently is that this function helps to maintain health by acting as an antioxidant in vivo.

Terpene is a generic term for derivatives such as alcohols, aldehydes, ketones, etc. The common feature of terpenes is that they are widely distributed in the plant system, and among them, monoterpenes, sesquiterpenes and diterpenes are easily distilled by steam distillation. Outflow (溜 出), and constitutes the main component of essential oils (精油). Among them, the monoterpenes are aromatic and the sesquiterpenes are generally odorless. Since ancient times, it has been used as a raw material for medicines and medicines, but it is also important as a raw material for chemical industry such as α-pinene and camphor.

The coating containing such a composition is also performed by a general wet coating method, and the surface coating is performed to a thickness of 0.1 to 10 mm by using a coercive spraying machine as a vegetable essential oil of the herbal component, to maintain antibacterial and deodorizing power.
