Such building materials are utilized as finishing materials such as interior materials, floor materials, etc., in the construction of buildings, and in particular, may be constructed in the form of board, paint, mortar, and the like.

By such a configuration, the building material according to the present invention exhibits a thermal conductivity of more than 0.58 Kcal / mhr ℃, the sound insulation rate of 15dB at 250Hz, 20dB at 1000Hz.

At this time, it is preferable that the finishing materials such as interior materials, flooring materials, etc. are usually constructed in the same manner as that of the construction, and only the difference is that their materials consist of the composition of the composition according to the present invention.

In addition, the building material of the present invention is applied to the outer surface of the building material composed of the above composition by applying a glaze such as cinnabar oil, blue oil, cheonmok oil, transparent oil, black oil, Ti-Co, Ti-Cu, Ti-Fe, etc. It is configured to give an interior effect by giving a back in various forms according to user's taste.

At this time, the functional natural minerals added may be germanium, natural materials such as ajacharcoal, rosin, etc. The addition amount is preferably 1 to 5% of the total weight of the building material.

Then, the reason for numerical limitation on the composition of the components of the building material of the present invention will be described.

(ocher)

Loess is a sediment consisting mainly of particles with a silt size of 0.002 to 0.005 mm in diameter and has a composition of components such as SiO ₂ , Al ₂ O ₃ , Fe ₂ O ₃ , MgO, CaCO ₃ , and solar energy. It is a substance called so-called living organisms by emitting a large amount of far-infrared rays necessary for the growth of animals and plants.

In particular, the publications published in the past (Cho Baek-hyun, 'Soilology'-Hakhaksa, 1980; Kim Gye-deok,' Analytical Chemistry Handbook '-Sehwahwa, 1993) or articles ("Soil Main Components (Si, Fe, Al, Mg, Ca)") Separation and Quantification-Kyu-Jin Chung, Mi-Kyung Kim, Tae-Ki Hong-Korean Journal of Environmental Analysis, Vol. 6 (No. 2) 153 ~ 155, 2003; "General Characteristics of Loess and Iron Oxide Contents-In-Kyu Kim, Sung-Hoon Suh, Jin-Yang Kang- KFDA, Kyung Hee University, As can be seen from Samyuk University Co., 2005.5.15), when ocher ingredient is absorbed by human body, it promotes metabolism, prevents aging, and activates the physiology of cells by radiating far-infrared rays. It also restores dying seas due to red tide.

In addition, it releases anions as much as vitamins in the air, converts the acidified constitution into alkaline, and promotes blood circulation, thereby boosting metabolism.

In addition, the loess contains an active yeast called caratase, which reduces and breaks down free radicals and peroxide lipids, which are the causes of aging, and decomposes harmful substances in the body. To summarize the efficacy: temperature control ability to prevent the heat of the outside and radiate warmth when cold; Ability to absorb food, tobacco, or other harmful odors quickly; Antibacterial activity that prevents the growth of fungi and various fungi harmful to the human body; Health care such as anti-aging, promoting blood circulation, relieving stress, skin care, nerve pain recovery, low back pain recovery and chronic fatigue recovery with high rate of far infrared radiation; It can be referred to as the electromagnetic wave shielding ability to block harmful electromagnetic waves by a large amount of far-infrared radiation.

In the present invention, in order to make the best use of the effects of the loess, it is preferable to contain 20 to 70% by weight, which is difficult to exhibit the efficacy of the loess when the ocher is added to 20% by weight or less, and is added to 70% by weight or more. Since the viscosity is too high in raw material blending and there is difficulty in mixing, it is preferable to limit the additive to the above range in consideration of the relationship with other component compositions.

(clay)

Clay is a fine soil particle with a diameter of 0.004mm or less. When the rock is weathered and decomposed, it mainly combines silicon, aluminum, and water to form a clay mineral. The clay mineral has a mica-like structure. There are also two-layer or three-layer structures.

These clays are kaolins, montmorillonite, illite, and the like. Water, potassium, iron, magnesium and the like enter into various clay minerals between layers, and all the coarse minerals other than quartz SiO ₂ are decomposed to become clay minerals.

In addition, since clay has a much larger surface area per unit weight than sand or silt, soil is the most active part along with corrosion and has a strong retention of moisture and nutrients, and has a high clay content. do.

In the present invention, it is intended to use a strong fire-resistant property to protect the internal material from fire because it enhances the bonding force of the clay properties, there is no emission of toxic gas due to combustion, and forms a carbon layer on the burned surface, Even in the particle size It is preferable to use a particle having a particle size of 0.001 ~ 0.004mm, which is less than 0.001mm, it is difficult to secure the surface pores in the intermediate products and final products such as boards, tiles, flooring, etc., if it is more than 0.004mm The particle size is preferable because of the disadvantage that the bonding force is sharply lowered.

In addition, in the present invention, it is preferable to add 17 to 23% by weight of clay having a size in the above range, which causes problems in fire protection such as toxic gas release due to flame combustion when the clay is added to 17% by weight or less. When added in more than 23% by weight it is preferable to add in the above range because the viscosity of the raw material kneading is difficult to process manufacturing process.

(Activated carbon)

Active carbon is a highly adsorptive material, and most of its constituents are carbonaceous materials. Mostly, wood, lignite, and peat are treated with chemicals such as zinc chloride or phosphoric acid, which are activated, and dried. Activate charcoal with water vapor.

Generally, activated carbon is manufactured in a powder state or a particle state, and powdered powder may be used in a particle state. Its use is mainly used to absorb gas or moisture as an adsorbent, and it is also used for various purposes such as solvent recovery and gas purification or bleaching.

Originally, activation means that atoms, molecules, or ions become high energy due to absorption of radiation or impact of high-speed particle beams, and thus change into a state that is likely to cause chemical reactions or crystal lattice. In addition, since the catalytic action means that the function of the surface is changed or the addition of other substances becomes much higher, and activated carbon also means that the carbonaceous function is improved by adding such an activator.

In the present invention, the activated carbon is used to further activate complex functions such as far-infrared emission, humidity control, filtration, anion release, deodorization, antibacterial, detoxification, the size is preferably 0.1-2 cm, which is the final It may vary depending on the intended use of the molding material of the product.

For example, when the final product is used as a flooring material, it is necessary to have a high-intensity, double-noise noise and vibration shielding effect. At this time, it is preferable to grind it to a size of about 2 cm. It is preferable to increase the bonding affinity between materials during material mixing by pulverizing to a size of.

In addition, the amount of activated carbon added in the present invention is preferably 5 to 10% by weight.

The reason for adding in such a range is that the purpose of adding activated carbon described above becomes meaningless if it is 5 wt% or less, and it is particularly preferable to add it in the above range because hardness of the product is lowered if it is 10 wt% or more.

(Oyster shell)

Oyster shell is composed of 94% by weight of calcium carbonate, 6% by weight of gypsum, etc., which is composed of most beneficial calcium components, exhibits noise shielding effect, and is used as a building material in terms of utilizing existing waste materials. Since it is a good material to be used, it is preferable to use it within the range which does not have a problem with the function as a building material and a hardness (hardness, strength, etc.).

In the present invention, the oyster shell is preferably crushed to a size of 0.1 ~ 1cm and then added in a range of 1 to 5% by weight.

As described above, 0.1cm or less, which limits the size of the oyster shell, increases the manufacturing cost due to high manufacturing cost, and more than 1cm causes problems in the bonding strength between the raw materials, and when the addition amount is 1% by weight or less, the noise shielding effect is insufficient. If it is 5% by weight or more, it is preferable to add oyster shell having the same size as above in the above range because it is inferior in hardness and strength as a building interior material.

In addition, when the oyster shell is used, it is preferable that the surface of the oyster shell is washed and the salt is adhered to the surface to be completely removed.

(amethyst)

Amethyst is a crystal with several shades of purple, a hexagonal granite belonging to a silicate mineral.

This amethyst is purple because it contains iron dioxide, the more iron oxide content, the darker the color.

It is known that the amethyst is twice as effective as white crystal. The nature is warm, the taste is sweet and very, and it is not poisonous. In particular, it acts on the meridians of the heart and the meridians attached to the liver to see the lack of heart, to treat the edema, to stabilize the mind, to lower the energy, to warm the uterus, to make the face shiny.

In particular, the amethyst has a hexagonal structure, regular vibration corresponding to 32786 Khz per second, and far infrared ray emission amount of 94%. However, the amethyst is excellent in maintaining body temperature, strengthening heart, analgesic and inflammation.

In the present invention, it is preferable to add 2 to 12% by weight of the powder of 100-300 mesh.

At this time, the amethyst powder of 300 mesh or more is difficult to use because the production cost is high, and the particle size of the above range is preferable because the amethyst powder of 100 mesh or less is difficult to uniformly mix.

In addition, the reason for limiting the amount of the amethyst added as described above is that when the weight is less than 2% by weight, the effect and effect cannot be expected. Do.

Tourmaline

Tourmaline is a mineral belonging to the hexagonal system, and its chemical composition is a complex borosilicate of aluminum, iron, magnesium, alkali metal, and the like.

It is usually hexagonal or nine-angled, sometimes triangular, and sometimes different in crystalline form. They also have flat rhombohedrons, needles, and hairs, and sometimes form granules or blocks. The cleavage is not clear, and the monocytes are not flat or shell-shaped. Hardness 7.0-7.5 and specific gravity 2.98-3.20. In addition, electricity is generated by friction, and this name is given because both ends are charged positively and negatively when heated. Many iron is called iron tourmaline, and it is black and many things are opaque to the naked eye.

This tourmaline is the negative ions generated by the human body improves the weak alkaline constitution, it will increase the anti-oxidation or immunity that causes aging. In addition, it is a useful mineral because it contains Mg good for cell activation, Fe good for the heart, B good for promoting the growth of the skin and mucous membranes, and Si good for the kidneys, liver, and stomach.

In the present invention, it is preferable to add tourmaline at a size of 150 to 250 mesh, and 5 to 10% by weight, which is less than 150 mesh. The production cost is high, it is difficult to use, even in the case of the added amount of less than 5% by weight of the tourmaline efficacy is hard to be expressed, and the manufacturing cost is high at 10% by weight or more is preferably added as the amount of the addition within the range of the particle size.

In addition, in the present invention, the phytoncide may be coated on the surface of the building material of the present invention in order not only to prevent cracking or chipping of the loess but also properly express various effects of the phytoncide which will be described later.

At this time, the amount of phytoncide used in the coating is preferably 1 to 5% by weight of the building material of the present invention.

Here, phytoncide (phytoncide) is a natural oil extracted from pine, fir, cypress, a substance consisting of phenolic compounds including terpenes, alkaloids, glycosides and the like.

These phytoncide can be absorbed through the forest bath, thereby relieving stress, strengthening the intestines and cardiopulmonary function, and sterilizing effect.

That is, the phytoncide is known to have a stress relief, sedation, comfort effect, allergy prevention, antibacterial action, deodorant effect.

Building material using the loess of the present invention having such a composition is to be manufactured through the following process, as shown in FIG.

That is, as shown in Figure 1, the building material of the present invention is prepared through the crushing step (S100) after preparing the above-described components and then subjected to the mixing step (S110) to be mixed in the above-described composition ratio.

At this time, the grinding step (S100) is to grind each of the components required to be crushed to have a predetermined particle size through a separate grinding process, the mixing step (S110) is an aqueous binder, preferably kneading using water Is made of.

In addition, the aqueous binder is not limited to water, and solutions such as chloroprene, polyvinyl acetate, polyacrylic acid ester, polyvinyl alcohol, carboxymethyl cellulose to facilitate and promote the mixing and adhesion of ocher, activated carbon and clay. Emulsion type synthetic binder aqueous binder can also be used.

Here, the aqueous binder is preferably used mixed in the range of 40 to 60% of the total weight of the mixture, which is used when less than 40% by weight is not uniform dispersion of activated carbon, such as light after the mixed layer is formed There is a risk that the activated carbon is easily damaged even when the impact and cracks are generated, and when used in more than 60% by weight, it is preferable to use within the above range because the function expressed from ocher, activated carbon, clay, etc. is relatively reduced.

 When such a mixing process (S110) is completed, the molding process (S120) is then performed.

The molding process (S120) is a process of extrusion molding the mixture kneaded and cut to a size suitable for molding, and then placed in a molding machine and compression molding.

The molding machine according to the present invention, as shown in FIG. 2, the sheath heater 140 on a part of the opposite surface of the lower mold 110 on which the mixture 100 is seated, and the press 130 operated by the operation cylinder 120. It is made of a built-in structure, the molding process is formed by applying the force of the press 130 approximately 100 ~ 400 Ton / ㎡ If the applied force exceeds 400 Ton / ㎡ pore of the compression molded molding (pore) ) Is too dense to match the degree of maneuverability to which the ocher can breathe, and it is necessary to be careful because the glaze cannot penetrate to the inside of the molded article in the glazing process (S140) described later.

At this time, the press 130 or the lower mold 110 may be molded into a variety of patterns or shapes suitable for the interior by putting a pattern of negative, embossed.

In addition, the sheath heater 140 during molding is preferably zoomed to preheat to a temperature of approximately 100 ~ 200 ℃ to shorten the drying time in the first drying step (S130) to be described later.

When the molded product is completed through the above process, a primary drying process (S130) for drying it is performed.

The first drying step (S130) is preferably using a drying facility that can be continuously processed in the form illustrated in Figure 3 in consideration of the production cost and productivity.

For example, as shown in FIG. 3, the conveyor belt 220 is installed through the inside of the hermetically sealed chamber 200 where hot air is constantly supplied by the hot air supply fan 210, and the conveyor belt 220 is installed. In the upper portion of the molding 100 'is passed in the seated state, the ceiling of the chamber 200 and the lower portion of the conveyor belt 220 in the heat source 230 is installed in the structure to increase the production efficiency inline (in -line).

At this time, the conveyor belt 220 is preferably a metal chain belt that can withstand heat sufficiently, the heat source 230 may be a siege heater, a halogen lamp, a ceramic heater, the heat generated by these heat sources 230 It is preferred that approximately 500 ~ 700 ℃, and the drive speed of the conveyor belt 220 is 10 ~ 100cm per minute so that the time the molded article 100 'stays in the chamber 200 is approximately 20 minutes Bar, the driving speed of less than 10cm per minute causes a sharp decrease in the production yield, and having a driving speed of more than 100cm per minute has the disadvantage that it does not dry, so it is most reasonable to control the speed range.

As such, the molded product 100 'molded and dried in the state of being completed up to the first process may be coated with a phytoncide solution and immediately commercialized to be used as interior materials.

In addition, after the first drying step (S130), glazing step (S140), secondary drying step (S150), polishing step (S160) is further performed for use as a more advanced interior material, flooring (S170) May be applied.

Here, the glazing process (S140) allows the outer surface of the molding 100 'to be designed in a desired color and pattern using any one selected from the above-described types of glazes.

In this case, as described above, the electromagnetic shielding function may be provided.

Then, when the glazing process (S140) is completed, the secondary drying step (S150) is performed to dry it, the secondary drying step (S150) is the drying equipment of the same structure used in the above-described primary drying step (S130) Using to increase the drying temperature to 1000 ~ 1300 ℃ to further increase the strength of the molding (100 ').

Further, the drying temperature may vary depending on the type of glaze and the coating thickness of the glaze, but is made within the above range.

In this state, of course, the final product can be made of interior materials, such as ocher boards, flooring material.

In addition, the polishing process S160 may be finally performed to provide a more advanced product.

In particular, the polishing step S160 is intended to further increase the leveling and glossiness required by the flooring material.

At this time, the polishing process (S160) may be performed by grinding and planarization work with diamond paper, loofah, sand paper, etc. In some cases, may be polished immediately after the first drying rather than the second drying.

By doing so, it is possible to construct a flooring material or interior material exhibiting characteristics of thermal conductivity of 0.58 Kcal / mhr ° C. or higher, 15 dB at a sound insulation rate of 250 Hz, and 20 dB at 1000 Hz.

In addition, a process of coating the phytoncide solution on the outer surface of the building material to a thickness of 5 to 20 μm after the first drying or the second drying may be performed.

This is the same as the reason described above.

EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described.
