The present invention relates to a method for manufacturing a building finishing material using a mineral material, and more particularly, to enhance the thermal insulation and humidity control ability and deodorization, sound insulation effect, to provide antibacterial and anti-mold effect, and to include a functional radiation-resistant shielding material. It relates to a method of manufacturing the finish.

Specific matters including the problem to be solved, the solution to the problem, and the effects of the present invention as described above are included in the embodiments and drawings to be described below. Advantages and features of the present invention, and methods for achieving them will be apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings.

Hereinafter will be described in detail with reference to the functional building finish manufacturing method drawings presented above.

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

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

If the firing temperature is less than 600 ℃, the harmful substances or impurities present in the diatomaceous earth or zeolite cannot be sufficiently decomposed and removed, and if it exceeds 800 ℃ may affect the bonding of the microporous crystal structure of the diatomaceous earth or zeolite It is preferable to bake on the said conditions.

In addition, when the firing time is less than 8 hours, the harmful substances or impurities present in the diatomaceous earth or zeolite may not be sufficiently decomposed and removed. If the firing time exceeds 12 hours, the harmful substances or impurities to be removed are already decomposed and additionally removed. Since heat is consumed, a problem arises in that the unit cost of building finishing materials increases.

Therefore, it is preferable to fire the diatomaceous earth or zeolite at 600 to 800 ° C. for 8 to 12 hours.

In addition, the diatomaceous earth is a single-cell phytoplankton diatoms die, deposited on the seabed or lake bottom and turned into soil after tens of millions of years, a part of the diatoms becomes crude oil (oil) and the rest is diatomaceous earth. Diatomaceous earth is fire resistant, so it is used as raw material for stove, fireproof brick. As a characteristic of diatomaceous earth, it is very resistant to fire, and it is a light substance having super porosity and ultrafine structure of 5,000 to 6,000 times than charcoal, and has excellent moisture absorption and moisture resistance.

In addition, the zeolite is a natural zeolite and a synthetic zeolite is present, the synthetic zeolite is made by the slow crystallization of silica alumina gel composed of a mixture of alkali, water and organic substrate. Synthetic zeolites are used as ion filters in soft water and water purification systems and can remove unwanted fission products from certain molecular and nuclear fuel industries from industrial emissions. Zeolites also serve as traps for large molecules and are used to speed up chemical processes such as alkylation in petrochemical engineering.

Next, in the second step (S20), the first mineral is ground to a size of 1 to 45㎛. Specifically, the first mineral is mixed with boron, barite, hard wool, pulverized with a ball mill for 48 to 50 hours, preferably pulverized to a size of 1 to 45㎛, the first mineral is barite with respect to 1 part by weight of boron It is preferable to mix 9-11 weight part and 90-110 weight part of mica.

The first mineral material serves to block the radiation leaking out of the nuclear building or the radiation workshop in the functional building finishing material of the present invention surrounding the limited area around the radiation source.

The radiation shielding design should consider α, β, γ, X-rays and neutron beams having various energies. Since the α-rays have a weak penetrating power, they can be shielded by a sheet of paper, and the β-rays can also be shielded by an aluminum plate of several mm. It is automatically shut off and the shielding is the basis for the actual shielding facility. The γ-rays and the high-speed neutron beams should be below the maximum allowed by law outside the shield. The shielding material for the high-speed neutron beams contain hydrogen and have a large specific gravity, so that concrete is often used in consideration of economy and flexibility in construction. However, concrete does not contain elements with large atomic numbers, so it is not effective for strong radiation sources such as nuclear reactors. Therefore, for the gamma ray, it is preferable to use a substance having a high molecular weight or to mix calcium, silicon, oxygen, and some iron oxide.

Therefore, the present invention is to effectively shield the radiation by using the chemical components contained in the first minerals boron, barite, biotite.

Boron is an essential nutrient for plants, with a ratio of about 0.001%, which is a relatively uncommon element, followed by diamond. Boron is used in various applications such as ceramic glazes, heat-resistant glass manufacturing, insecticides, fluxes, detergent additives, and trace additives in semiconductors, and in the manufacture of thermal neutron regulators, radiation shields, reinforced glass fibers, and lightweight structures in the aerospace industry. Boron compounds are also used. In particular, it is possible to shield the neutron beam by mixing boron oxide with a large absorption cross-sectional area of the slow neutron in the concrete.

The barite is a mineral belonging to a tetragonal system and its chemical component is barium sulfate (BaSO ₄ ), and forms a solid solid with celesite by substitution of Ba and Sr. Barium (Ba) is one of the highly reactive alkaline earth metal elements, and exists in nature mainly as barium sulfate ore of barite. Barite is used as an aid in drilling for oil and natural gas and is used to extract barium (Ba). Barium (Ba) is used as a raw material in the manufacture of paints, carpets, and fabrics, and it is used as a filler for paper by re-precipitating Ba (Ba), as a raw material for cosmetics, as a pigment for paints, as a contrast agent for radiography, etc. Used. Barium (Ba) is an X-ray contrast agent, because it has a high X-ray absorption and low solubility, so it is used to inspect the intestines, especially the digestive tract.

Therefore, in order to use barium (Ba) of barite as a material capable of absorbing and blocking X-rays from radiation in the functional building finishing material, a process of purifying quartz, iron, zinc, and lead, which are impurities included in barite, is essential.

The mica is a generic term for dense or fine scaly mica. It is also called sericite. Cicadas vary in their use due to their excellent far-infrared and deodorant effects. Although it is a highly plastic clay mineral, it contains potassium oxide (K ₂ O), which is a very useful mineral that acts as a plasticizer and flux. It is used in ceramics or welding rods. In addition, since the particles are fine and flaky to easily cover objects, they are used in textiles, fillers, and abrasives in addition to blending materials such as paints, pigments, pharmaceuticals, and cosmetics.

It can be expected that the first mineral material according to the present invention can shield radiation around a radiation source that could not normally be shielded with concrete. If the first mineral is boron, barite, hard wool pulverized with a ball mill for 48 to 50 hours can be ground to a size of 1 to 45㎛. The pulverized first mineral can extract a heavy element which is a main component of the first mineral through the following steps to obtain the effect of shielding radiation when used as a building finishing material mixed with the diatomaceous earth or zeolite.

When the grinding time is less than 48 hours, the grinding of the first mineral is not effectively performed. When the grinding time exceeds 50 hours, the first mineral is already ground to a size of 1 μm, which is a size suitable for the material of the present invention. Since the case is 48 to 50 hours is preferable.

In addition, the smaller the particle size after the grinding of the first mineral is effective, 10㎛ is the most effective particle size.

If the particle size of the first mineral material is less than 1㎛ requires an additional process, the manufacturing cost increases, and if it exceeds 45㎛ the surface area of the pulverized first mineral is small used as the building finishing material of the present invention When the radiation shielding effect is significantly lowered.

In addition, the mixing conditions of the first mineral is preferably 9 to 11 parts by weight of barite, 90 to 110 parts by weight of mica based on 1 part by weight of boron.

When the barite is less than 9 parts by weight of the barite, the relative mixing ratio of barium (Ba) of barite may be too low, so that the X-ray shielding function may be insignificant, and when the amount exceeds 11 parts by weight, the mixing ratio of boron is too low. The problem that the neutron shielding function is lowered.

In addition, when the amount of boron is less than 90 parts by weight with respect to 1 part by weight of boron, the relative mixing ratio of potassium oxide (K ₂ O) of the mica is small, the function of oxidizing and shielding the radioactive material may be insignificant, if the amount exceeds 110 parts by weight There is a problem that the unit price rises.

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

Next, in the third step (S30) to produce a second mineral by mixing 2 to 4 parts by weight of the calcined diatomaceous earth or zeolite with respect to 1 part by weight of calcite.

The calcite is a chemical component of calcium carbonate (CaCO ₃ ) as a kind of anhydrous carbonate mineral, showing a beautiful crystal form and is colorless and transparent. When heated, it releases carbon dioxide and reacts violently with dilute acids to release gases. The calcite is used as a material in 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 based on 1 part by weight of calcite.

When mixed with less than 2 parts by weight of diatomaceous earth or zeolite with respect to 1 part by weight of calcite, the mixing ratio of calcite is relatively high, thereby preventing micropores of diatomaceous earth or zeolite, resulting in poor thermal insulation and humidity control, and exceeding 4 parts by weight. The weight of the functional building finishing material of the present invention is lowered, the problem occurs that the function is insignificant.

Next, in the fourth step (S40) by mixing and stirring the natural pulp and water to produce a natural pulp decomposition product. Specifically, 2 to 10 parts by weight of water is mixed with respect to 1 part by weight of the natural pulp and stirred at 3000 to 4000 rpm at 60 to 80 ° C. In addition, the natural pulp is preferably short fibers.

The natural pulp is made of coniferous trees such as spruce, fir, secretion, and staple as main raw materials. Natural pulp used in the present invention is a short fiber is a short fiber usually having a length of 2.5 to 3.8cm. In the case of using the short fiber, it is preferable to use the short fiber because it can prevent agglomeration or entanglement with the mixture in the stirring process performed in the following step.

In addition, when mixing less than 2 parts by weight of water with respect to 1 part by weight of the natural pulp, the natural pulp is not sufficiently decomposed in the water does not occur properly in the mixing step carried out in the following steps, relative to 10 parts by weight As the ratio of the water is high, there is a problem that the effect of the functional building finishing material according to the present invention is insignificant.

In addition, when the stirring temperature is less than 60 ℃ temperature is too low may not be appropriately mixed in this step, and if it exceeds 80 ℃ evaporation of the water occurs it may be difficult to proceed the stirring process of this step.

In addition, when the stirring speed is less than 3000rpm, the natural pulp is not sufficiently decomposed in the water, so that the mixing process performed in the following step does not occur properly. When the stirring rate exceeds 4000rpm, the natural pulp may be agglomerated or entangled. There is this.

As shown in FIG. 2, the pores of the diatomaceous earth or zeolite are secured through the natural pulp and crosslinking between the diatomaceous earth or the zeolite particles enables the movement of moisture or organic materials between particles, thereby providing a comfortable space inside the building finish material. To be possible. In addition, the natural pulp serves as a straw to absorb moisture inside the diatomaceous earth or zeolite to prevent condensation of the finish. Therefore, the functional building finishing material produced by the manufacturing method of the present invention serves to effectively perform the insulation, humidity control, deodorizing function by maintaining the pores.

Next, in the fifth step (S50) is added after the predetermined plant extract to the natural pulp decomposed product produced in the fourth step (S40) and dispersed, pressurized to 3 to 5 atm to the natural pulp decomposed tissue Adsorb predetermined plant extracts. Specifically, the plant extract is preferably any one selected from the pore hole extract to ginkgo leaf extract, it is preferable that the selected plant extract is 0.1 to 0.3 parts by weight based on 1 part by weight of the natural pulp decomposed in the fourth step (S40). .

The pore pore extract is extracted from plants belonging to the pore or upstream family containing red branched pigment called betain in the fruit, has excellent antibacterial and antiviral activity.

The ginkgo biloba extract is extracted from dried leaves of ginkgo biloba, and is approved and sold in Korea. Camphorol (Kaempferol) contained in the ginkgo biloba has a strong antioxidant action to prevent oxidation of fat and DNA as a yellow flavonoid, strong antibacterial action against the tuberculosis, staphylococcus, streptococci, diphtheria bacteria, anthrax bacteria, E. coli and antifungal There is action.

When the amount of the plant extract is less than 0.1 parts by weight of the selected plant extract from ginseng extract to ginkgo leaf extract based on 1 part by weight of the natural pulp decomposed in the fourth step (S40), the ratio of the plant extract is so low that the antibacterial and antifungal effects may be insignificant. If the plant extract exceeds 0.3 parts by weight, the toxicity contained in the plant extract may cause side effects.

In addition, when the pressure is less than 3 atm, there may be a problem that the plant extract is not sufficiently adsorbed to the natural pulp, and if the pressure exceeds 5 atm because the deformation of the plant extract or natural pulp may occur. It is preferable.

By adsorbing the plant extract on the natural pulp provides an excellent antibacterial and antifungal effect.

Next, in the sixth step (S60), a paste is prepared by mixing the natural pulp decomposed product produced in the fifth step (S50), the first mineral and the second mineral and a predetermined functional mixture. Specifically, the paste is prepared by stirring at 65 to 75 ° C. for 2 to 3 hours at 250 to 350 rpm. In addition, 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) based on 1 part by weight of elvan.

The elvan is a rock belonging to granites. The main components are silicic anhydride and aluminum oxide, and a small amount of ferric oxide is contained. Use is used as a filter for tablets or as an anti-inflammatory for treating skin diseases. The elvan is composed of 3 to 150,000 holes per cubic centimeter, and thus has strong adsorption properties and is used as a toxic metal remover because it functions to exchange ions with heavy metals, and is known to emit far infrared rays when heated.

The rutile is titanium dioxide (TiO ₂ ) as the main component is also called rutile, is efficient as a semiconducting material and is used as a porcelain raw material.

The starch can be used in finishing materials to control viscosity or as an adhesive.

The yttylene vinyl acetate (EVA) is used to prevent slipping on the surface of the building material and to bond the joints for cracking and repair.

If the mixing temperature is less than 65 ℃ there is a problem that the sufficient mixing of the first mineral and the second mineral and the functional mixture does not occur, if the temperature exceeds 75 ℃ may be a deformation of the mineral and natural pulp mixed in this step. .

In addition, when the stirring speed is less than 250rpm there is a problem that the sufficient mixing of the first mineral and the second mineral and the functional mixture does not occur, and if the stirring speed exceeds 350rpm the problem occurs that the deformation of the functional mixture occurs too fast .

In addition, when the mixing time is less than 2 hours, there is a problem in that the prepared paste does not form a uniform mixture, and when the mixing time is more than 3 hours, the mixing time is too long, so that the viscosity of the prepared paste is high, making it difficult to mix. It is preferable to mix in said time.

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

First, mortar is manufactured using the paste of the sixth step. Specifically, mortar is prepared by further adding 30 to 50 parts by weight of water and 0.01 to 0.5 parts by weight of starch based on 1 part by weight of the paste.

When the water is added less than 30 parts by weight with respect to 1 part by weight of the paste, the strength of the prepared mortar is increased and cracks are generated. When the water is added by more than 50 parts by weight, the workability is improved but the strength is increased. It is preferable to mix under the above conditions because a problem occurs that becomes low.

In addition, the starch is adjusted to the mixing ratio according to the convenience of the manufacturer, but mixing in the weight portion to give an effective adhesion to the prepared mortar can be prepared in the desired form mortar.

In addition, the paint is prepared 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 and mixed with 1 part by weight of the paste.

The EVA is a polymer obtained by copolymerizing ethylene and vinyl acetate monomer, and low content EVA is processed like polyethylene with low density to have excellent impact resistance and stress cracking resistance at low temperature, and thus a heavy packaging material and a laminate film are used for the adhesive. 10 ~ 20% of EVA is used in the same concentration as soft vinyl chloride such as foam molded products such as sandals and soles, agricultural film, and stretch film for business. High concentrations of EVA are used as raw materials for adhesives.

When the water is mixed at less than 100 parts by weight of the paste 1 part by weight, the concentration of the produced paint is dark, so that the applicability is lowered. When the water is mixed by more than 150 parts by weight, the concentration of the prepared pate is The problem arises that the work efficiency is lowered.

In addition, when the EVA is mixed in an amount of less than 30 parts by weight with respect to 1 part by weight of the paste, the adhesiveness of the manufactured paint is inferior, and when the EVA is mixed in an amount exceeding 50 parts by weight, the applicability is good. There is a problem that the efficiency of the work is deteriorated.

In addition, the starch is adjusted to the mixing ratio according to the convenience of the manufacturer, it is preferable to mix in the weight ratio.

In addition, a board or a tile is manufactured using the paste of the sixth step. Specifically, the paste is placed in a mold, pressurized, dried in a dryer at 130 to 170 ° C. for 3 to 5 hours, and naturally dried for 3 to 6 hours to prepare a board to tile.

If the drying temperature is less than 130 ℃ problem occurs that does not dry enough to the inside of the manufactured board or tile, and if it exceeds 170 ℃ there is a problem that a crack occurs due to a sudden rise in temperature it is to dry at the temperature desirable.

In addition, when the drying time is less than 3 hours, there is a problem that does not dry enough, and when more than 5 hours there is a problem that the uniformity of the board to the tile is preferable to dry in the above conditions.

In addition, when the natural drying is less than 3 hours, when the manufactured board or tile is used as a finishing material, there is a problem in that it does not prevent the bending or cracking due to a sudden temperature change. It is preferable to dry naturally under the above conditions because an increase in problems occurs.

In addition, a molded article is manufactured using the paste of the sixth step. Specifically, the paste is placed in a mold, pressurized, dried in a dryer at 100 to 150 ° C. for 4 to 6 hours, and naturally dried for 3 to 6 hours to prepare a board to tile.

When the drying temperature is less than 100 ° C there is a problem that does not dry enough to the inside of the manufactured molded article, and if it exceeds 150 ° C it is preferable to dry at the temperature because there is a problem that a crack occurs due to a rapid rise in temperature.

In addition, when the drying time is less than 4 hours, there is a problem that does not dry enough, and if more than 6 hours there is a problem that the uniformity of the board to the tile is preferable to dry in the above conditions.

The molded article is manufactured by molding a product that can be used to enhance the insulation effect, humidity control and deodorization, sound insulation effect, and to solve the bacteria and mold problems, in a preferred embodiment the molded article is an egg that can be used in a general refrigerator Manufactured as a frame, it is prepared to enhance the removal of odor and antibacterial effect in the refrigerator.
