BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention and the manner of achieving them will become apparent by reference to an embodiment which will be described in detail below with reference to the accompanying drawings.

Hereinafter, the functional building finishing material manufacturing method will be described in detail with reference to the drawings.

<Manufacturing Method of Multifunctional Building Finishing Material>

1 is a flowchart showing a flow of a method for manufacturing a functional building finishing material according to the present invention.

First, in the first step S10, diatomaceous earth or zeolite is fired to decompose harmful substances of the diatomite or zeolite. Specifically, the diatomite or zeolite is preferably calcined at 600 to 800 ° C for 8 to 12 hours.

If the calcination temperature is less than 600 ° C, harmful substances or impurities existing in the diatomite or zeolite can not be sufficiently decomposed and removed. If the calcination temperature is more than 800 ° C, it may affect the binding of the fine porous crystal structure of diatomite or zeolite It is preferable to perform firing under the above conditions.

If the calcination time is less than 8 hours, harmful substances or impurities existing in the diatomite or zeolite can not be sufficiently decomposed and removed. If the calcination time exceeds 12 hours, harmful substances or impurities to be removed are already decomposed There is a problem that the unit cost of the building finishing material is increased because heat is consumed.

Therefore, it is preferable to calcine the diatomite or zeolite at 600 to 800 ° C. for 8 to 12 hours.

In addition, the diatomaceous earth is a single-celled phytoplankton, diatom, which has died and has been deposited on the bottom of the lake or lake and transformed into soil after tens of millions of years. Some of the diatoms become crude oil (petroleum) and the remainder become diatomaceous earth. Because diatomaceous earth is strong against fire, it is used as raw material of stove stove and refractory insulation brick. Characteristics of diatomaceous earth are very strong to fire, light material with super porous and ultra fine structure of 5,000 to 6,000 times larger than char, and excellent in moisture absorption and moisture absorption.

The zeolite also has natural zeolite and synthetic zeolite, and the synthetic zeolite is made by slowly crystallizing a silica alumina gel composed of a mixture of alkali, water and organic substrate. Synthetic zeolites are used as ionic filters in water softeners and water purification systems and can remove unwanted fission products from the industrial emissions of certain molecules and the nuclear fuel industry. In addition, zeolites serve as traps for large molecules and are used to speed up chemical processes such as alkylation of petrochemical engineering.

Next, in the second step S20, the first mineral is pulverized to a size of 1 to 45 mu m. Specifically, it is preferable that the first mineral is pulverized with a ball mill for 48 to 50 hours by mixing boron, barite and rhizome, and pulverized to a size of 1 to 45 탆. 9 to 11 parts by weight, and sericite of 90 to 110 parts by weight.

The first mineral surrounds a limited area around the radiation source in a nuclear facility or a radiation workplace in the functional building finishing material of the present invention to shield the radiation leaking to the outside.

The radiation shielding design should take into consideration, for example, α, β, γ, X-rays and neutron beams having various energies. Since the? -Ray is shielded by a sheet of paper with weak penetration power and the? -Ray can also be shielded by an aluminum plate of several mm in thickness, if the? -Ray, the X-ray and the high-speed neutron beam having large permeability are effectively blocked, The shielding is automatically cut off and the shielding of these radiation is the basis for the actual shielding facility. The gamma -ray and fast neutron beams should be below the maximum allowable amount prescribed by law outside the shield. The shielding material for the high-speed neutron beam contains hydrogen and has a high specific gravity, and concrete is often used in view of economical efficiency and flexibility in construction. However, concrete is not effective for strong radiation sources such as reactors because it does not contain large atomic elements. Therefore, it is preferable to use a substance having a high molecular weight for the? -Ray or to mix calcium, silicon and oxygen with some iron oxide.

Accordingly, the present invention intends to effectively shield radiation by using chemical components contained in boron, barite, and sericite, which are the first minerals.

The amount of boron present as an essential nutrient of plants is about 0.001%, which is a relatively uncommon element and is harder next to diamond. Boron is used in various applications such as ceramic glaze, heat-resistant glass manufacturing, insecticide, flux, detergent additive, and a small amount of additives for semiconductors. In the nuclear reactor, thermal neutron modifier and radiation shielding, tempered glass fiber, Boron compounds are used. In particular, neutron beams can be shielded by mixing boron oxide, which has a large absorption cross section of slow neutrons, into concrete.

The barite is a mineral belonging to orthorhombic system. The chemical component is barium sulphate (BaSO ₄ ) and forms celestite and complete solid solution by substitution of Ba and Sr. Barium (Ba) is one of the highly reactive alkaline earth metal elements, and is present in natural barium sulfate ores mainly in the form of barite. Barite is used as an auxiliary material when drilling to find oil fields or natural gas and is used to extract barium (Ba). Barium (Ba) is used as a raw material in the production of paints, carpets, and fabrics. It is used as a filler for paper by reprecipitating barium (Ba), as a raw material for cosmetics, as a coloring agent for paints, Is used. Barium (Ba) has high X-ray absorbing power and low solubility and is harmless, so it is used as an X-ray contrast agent for the examination of internal organs, especially digestive tract.

Therefore, in order to use barium Ba as a material capable of absorbing and blocking X-rays in the functional building finishing material, it is essential to purify quartz, iron, zinc and lead which are impurities contained in the barite.

The sericite is a generic term of sericite, which is a dense or fine scaly muscovite. The sericite has various uses due to its excellent far infrared effect and deodorizing effect. It is a clay mineral with high plasticity, but it contains potassium oxide (K ₂ O) and is a very useful mineral that plays a role both as a plasticizer and a flux. It is used for raw materials for ceramics or electrodes. In addition, since the particles are fine and scaly and easily covered with an object, they are also used in the textile industry, fillers and abrasives in addition to the raw materials such as paints and pigments, medicines and cosmetics.

It can be expected that it is possible to shield the radiation around the radiation source which could not be normally shielded by the concrete by the first mineral according to the present invention. The first mineral boron, barite, and wormwood may be ground to a size of 1 to 45 탆 by pulverizing the balloon for 48 to 50 hours. The ground first mineral can extract a heavy element, which is a main component of the first mineral, through the following steps, so that it is mixed with the diatomite or zeolite to obtain the effect of shielding radiation when used as a building finishing material.

If the crushing time is less than 48 hours, the crushing of the first minerals can not be performed effectively. If the crushing time exceeds 50 hours, the first minerals are already crushed to a size of 1 mu m which is a suitable size for the material of the present invention, It is preferable that the above condition is 48 to 50 hours.

Further, the smaller the particle size of the first mineral is, the more effective it is, and the most effective particle size is 10 탆.

If the particle size of the first mineral is less than 1 mu m, a further process is required, resulting in an increase in manufacturing cost. When the particle size of the first mineral exceeds 45 mu m, the surface area of the crushed first mineral is small, There is a problem that the radiation shielding effect is remarkably lowered.

The mixing ratio of the first mineral is preferably 9 to 11 parts by weight, and 90 to 110 parts by weight, per 1 part by weight of boron.

When the amount of barite is less than 9 parts by weight with respect to 1 part by weight of the boron, the relative mixing ratio of barium (Ba) in the barite is too low, so that the X-ray shielding function may be insufficient. When the amount is more than 11 parts by weight, There arises a problem that the neutron beam shielding function is lowered.

If the amount of the sericite is less than 90 parts by weight based on 1 part by weight of the boron, the relative mixing ratio of potassium oxide (K ₂ O) of the sericite may be small and the function of shielding the radiation may be insufficient. There is a problem that the unit price increases.

Therefore, it is preferable to prepare the first mineral by mixing under the above conditions.

Next, in the third step (S30), the calcined diatomite or 2 to 4 parts by weight of zeolite is mixed with 1 part by weight of calcite to prepare a second mineral.

Calcite is a calcium carbonate (CaCO ₃ ), a kind of carbonate anhydrous minerals that shows a beautiful crystal form and colorless and transparent. When heated, it releases carbon dioxide and reacts violently with dilute acid to release gas. Calcite is used as a material for all industries such as cement industry, plastic industry, glass industry, and ceramics industry.

The second mineral is preferably mixed with 2 to 4 parts by weight of diatomaceous earth or zeolite with respect to 1 part by weight of calcite.

When mixed with less than 2 parts by weight of diatomaceous earth or zeolite relative to 1 part by weight of the calcite, the mixing ratio of the calcite is relatively high, thereby blocking the micropores of the diatomaceous earth or zeolite to deteriorate the heat insulating effect and humidity control ability. The weight of the functional building finish material of the present invention is lowered and the function thereof is insignificant.

Next, in the fourth step (S40), natural pulp and water are mixed and stirred to produce a natural pulp decomposition product. Specifically, 2 to 10 parts by weight of water is mixed with 1 part by weight of the natural pulp, and the mixture is stirred at 60 to 80 DEG C at 3000 to 4000 rpm. The natural pulp is preferably a short fiber.

The natural pulp is produced mainly from coniferous trees such as spruce, fir, secretory tree, and bole. The natural pulp used in the present invention is short fiber, which is usually short fiber having a length of 2.5 to 3.8 cm. When the short fibers are used, it is preferable to use short fibers because they can prevent aggregation or entanglement with the mixture in the stirring process performed in the following step.

In addition, when 1 part by weight of the natural pulp is mixed with less than 2 parts by weight of water, the natural pulp is not sufficiently decomposed in the water, so that the mixing process is not properly performed. The proportion of water is high, so that the effect of the functional building finish material according to the present invention is insignificant.

If the agitation temperature is less than 60 ° C, the temperature may be too low to mix well in this step. If the agitation temperature exceeds 80 ° C, evaporation of the water may occur and stirring of this step may become difficult.

If the agitation speed is less than 3000 rpm, the natural pulp is not sufficiently decomposed in the water, so that the mixing process performed in the following step is not properly performed. When the agitation speed is more than 4000 rpm, the natural pulp tends to aggregate or tangle .

As shown in FIG. 2, the diatomite or zeolite secures pores through the natural pulp and performs cross-linkage between the diatomite or zeolite particles to move moisture or organic matter between the particles, thereby allowing a comfortable space . In addition, the natural pulp serves as a straw for allowing water to be absorbed into the diatomite or zeolite, thereby preventing condensation of the finishing material. Accordingly, the functional building finish material produced by the manufacturing method of the present invention plays a role of effectively maintaining the heat insulation, humidity control, and deodorizing function by maintaining pores.

Next, in a fifth step S50, a predetermined plant extract is added to the decomposed natural pulp produced in the fourth step (S40), dispersed, and then the mixture is pressurized at 3 to 5 atmospheres, And adsorbs predetermined plant extracts. Specifically, it is preferable that the plant extract is one selected from perennial extract and ginkgo leaf extract, and 0.1 to 0.3 part by weight of the selected plant extract is preferable to 1 part by weight of the natural pulp in the fourth step (S40) .

The peritoneal extract is an extract of a plant belonging to the overgrowth or the upper branch which contains a red coloring pigment called betaine in the fruit and has excellent antimicrobial and antiviral activity.

The Ginkgo biloba extract is a dried leaf of Ginkgo biloba extract, which is approved and marketed as a medicinal product in Korea. Kaempferol contained in Ginkgo leaf is a yellow flavonoid and has a strong antioxidant effect against the oxidation of fat and DNA. It has a strong antimicrobial activity against antimicrobial activity against Mycobacterium tuberculosis, Staphylococcus aureus, Streptococcus, Diphtheriae bacteria, It works.

When 1 part by weight of the natural pulp decomposed in the fourth step (S40) is mixed with less than 0.1 part by weight of the plant extract selected from the perennial extracts and the ginkgo biloba extracts, the ratio of the plant extracts is too low, so that the antibacterial and antifungal effects are insignificant If the amount of the plant extract is more than 0.3 parts by weight, the toxicity contained in the plant extract may cause adverse effects.

If the pressure is less than 3 atm, the plant extract may not be sufficiently adsorbed to the natural pulp. If the pressure exceeds 5 atm, the plant extract or the natural pulp may be deformed. Therefore, .

The plant extract is adsorbed on the natural pulp to provide excellent antimicrobial and antifungal functions.

Next, in a sixth step (S60), the natural pulp decomposition product produced in the fifth step (S50), the first mineral and the second mineral are mixed with a predetermined functional mixture to prepare a paste. Specifically, the paste is prepared by stirring at 65 to 75 캜 for 2 to 3 hours at 250 to 350 rpm. Also, the functional mixture is mixed with 1 to 4 parts by weight of rutile, 8 to 12 parts by weight of starch and 10 to 40 parts by weight of ethylene-vinyl acetate (EVA) per 1 part by weight of elvan.

The elvan is a rock belonging to the granite type, and its main components are anhydrous silicic acid and aluminum oxide and contains a small amount of 2 iron oxides. The application is used as an anti-inflammatory agent to treat pills or skin diseases. The elvan is composed of 3 to 150 thousand holes per cm 3, and has a strong adsorption property. It acts as a harmful metal removing agent because it acts to exchange ions with heavy metals. It is known that it releases far-infrared rays when heat is applied.

The rutile is also referred to as rutile as titanium oxide (TiO ₂ ) as the main component, and is efficient as a semiconducting material and used as a raw material for ceramics.

The starch is used as a finishing agent to control viscosity or as an adhesive.

The ethylene vinyl acetate (EVA) is used to prevent sliding on the surface of building materials and to bond the joints for cracking and repairing.

If the mixing temperature is lower than 65 ° C., there is a problem that the first mineral and the second mineral are not sufficiently mixed with the functional mixture. If the mixing temperature is higher than 75 ° C., the mineral and natural pulp to be mixed in this step may be deformed .

If the stirring speed is less than 250 rpm, there is a problem in that the first mineral and the second mineral are not sufficiently mixed with the functional mixture, and when the stirring speed is more than 350 rpm, the stirring speed is too fast to cause the deformation of the functional mixture .

If the mixing time is less than 2 hours, the paste can not form a homogeneous mixture. If the mixing time is more than 3 hours, the paste is too long to be mixed because the paste has a high viscosity. It is preferable to mix them at the above times.

Next, mortar, paint and board or tile are manufactured using the paste prepared in the sixth step.

First, the mortar is manufactured using the paste of the sixth step. Specifically, 30 to 50 parts by weight of water and 0.01 to 0.5 parts by weight of starch are added to 1 part by weight of the paste to prepare a mortar.

When the water is added in an amount of less than 30 parts by weight based on 1 part by weight of the paste, the strength of the prepared mortar is increased but cracks are generated. When the water is added in an amount exceeding 50 parts by weight, workability is improved, It is preferable to mix them under the above conditions.

In addition, the starch may be mixed with the weight of the starch by adjusting the mixing ratio according to the convenience of the manufacturer, thereby effectively providing adhesion to the prepared mortar to produce a mortar of a desired shape.

Also, the paint is manufactured using the paste of the sixth step. Specifically, 100 to 150 parts by weight of water, 30 to 50 parts by weight of EVA and 0.01 to 0.5 parts by weight of starch are added to 1 part by weight of the paste and mixed.

The EVA (EVA) is a polymer obtained by copolymerizing ethylene and a vinyl acetate monomer. The EVA having a low content of EVA is processed like a low-density polyethylene and has excellent impact resistance and cracking resistance at low temperatures, and thus a heavy-weight material and a laminate film are used in adhesives. 10 to 20% of EVA is used for soft PVC such as foamed molded products such as sandals and sole, agricultural films, and commercial stretch films. The high concentration of EVA is used as a raw material for the adhesive.

When 1 part by weight of the paste is mixed with water in an amount of less than 100 parts by weight, there is a problem that the prepared paint has a thickened concentration and the spreadability is lowered. When the water is mixed in an amount exceeding 150 parts by weight, The efficiency of the work is deteriorated.

When the EVA is mixed with less than 30 parts by weight of the paste, the adhesiveness of the prepared paint is lowered. When the EVA is mixed with the EVA in an amount exceeding 50 parts by weight, The efficiency of the work is deteriorated.

Also, the starch is preferably mixed at the weight ratio by adjusting the mixing ratio according to the manufacturer's convenience.

Also, the board or tile is manufactured using the paste of the sixth step. Specifically, the paste is put in a mold and pressure is applied. The paste is dried in a dryer at 130 to 170 ° C for 3 to 5 hours, and then dried naturally for 3 to 6 hours to prepare a board or a tile.

If the drying temperature is less than 130 ° C, the inside of the manufactured board or tile may not be sufficiently dried. If the drying temperature is more than 170 ° C, cracks may occur due to an abrupt temperature increase. desirable.

If the drying time is less than 3 hours, the drying is not sufficiently performed. If the drying time is more than 5 hours, the board or tile may be uniformly formed.

Also, when the natural drying is less than 3 hours, there is a problem that warpage or breakage can not be prevented due to rapid temperature change when the manufactured board or tile is used as a finishing material, and if it exceeds 6 hours, It is preferable to naturally dry under the above conditions.

Further, a molded article is manufactured using the paste of the sixth step. Specifically, the paste is put in a mold and pressure is applied. The paste is dried in a dryer at 100 to 150 ° C for 4 to 6 hours and dried naturally for 3 to 6 hours to prepare a board or a tile.

If the drying temperature is less than 100 ° C., the inside of the molded product may not be sufficiently dried. If the drying temperature is more than 150 ° C., cracks may occur due to an abrupt temperature increase.

Further, when the drying time is less than 4 hours, a problem of not drying sufficiently occurs. When the drying time exceeds 6 hours, there is a problem that the board or tile is uniformly formed.

The molded article is manufactured by molding a product that can be used in a place where it is desired to solve the problem of bacteria and fungus by enhancing the heat insulating effect, the humidity controlling ability, the deodorizing and sound insulating effect, and the molded article is an egg So that the odor can be removed and the antibacterial effect of the refrigerator can be enhanced.
