Description

Artificial stone composition and its manufacturing method {ARTIFICIAL STONE COMPOSITION AND METHOD OF MAKING THESAME}

The present invention relates to an artificial stone composition and a method for producing the same, and relates to an artificial stone composition and a method for producing the same that can improve the environment by sterilization, disinfection, purification, neutralization and alkalinization.

Looking at the known technology known to the prior art artificial stone composition, it can be divided into three methods, the first method using a mixture of organic binders, such as natural or artificial aggregates and thermosetting resins, and the second aggregate and It is a method of manufacturing by mixing and curing cement-based hydraulic binders and the third method of manufacturing artificial stone by melting the rock or slag at a high temperature to solidify in a certain form.

Among the three methods, the first method is Japanese Unexamined Patent Publication No. 2000-128603 "Manufacturing method of artificial stone", Japanese Patent Laid-Open No. 1999-322392 "Antibacterial artificial stone and its manufacturing method", Republic of Korea Patent Publication No. 2001-054388 "Method of manufacturing artificial pillars", No. 2001-040345, "Non-slip artificial stone", and No. 2000-075211, "Method of manufacturing artificial stone using jade powder".

In these materials, natural or artificial aggregates and powders are mixed with thermosetting resin binders, which are difficult to handle and tend to be cured or uncured during use. Therefore, products cannot be manufactured consistently. It is difficult to manufacture large artificial stones.

The second method is Japanese Unexamined Patent Publication No. 1998-167794, "Manufacturing method of cement composition and artificial stone for artificial stone", Japanese Patent No. 195-010659, "Concrete having expressed plastic seat on the surface of concrete product", Republic of Korea Patent Publication No. 2001-109439 "Artificial stone with phosphorescent body and its manufacturing method", No. 1999-087761 "Method for manufacturing high-durability artificial stone modified by polymer material", No. 2001-026447 "Artificial stone and its Manufacturing method, use of charcoal powder, cement and ink ". In these materials, natural or artificial aggregates and powders are mixed with 10 to 20% by weight of a thermosetting resin binder. This method is difficult to handle resin binders as in the first method. There is a tendency to not manufacture products consistently and the production cost is high, making it difficult to manufacture large artificial stones.

Third, as for molten artificial stone, the molten molded product obtained by melting and solidifying an incinerator residue in a melting furnace and solidifying the surface is ground and polished as in Japanese Patent Application Laid-Open No. 2001-163643. Patent No. 1996-151242, "Method for producing calorie tides," describes a method for producing color artificial stones by adding a reducing agent such as tin oxide, mainly based on blast furnace slag, and in Korean Unexamined Patent Publication No. 1996-151240, "Method of Manufacturing" describes a method of adding feldspar, quicklime, and the like to the blast furnace slag to melt it. These manufacturing methods must be installed in the manufacturing facilities such as melting furnaces in common because it is difficult to expect industrialization because of the increase in manufacturing cost and consumption of a large amount of energy.

In addition, in the case of the existing artificial stone composition, it was difficult to obtain effects such as antibacterial, deodorization and far-infrared emission.

The present invention is based on Portland to improve the above-mentioned disadvantages Adding a high-strength admixture, sand, and GNC environmental improver to cement, an artificial stone composition capable of releasing antibacterial, deodorant and far infrared rays as well as disinfecting, disinfecting, purifying, neutralizing and alkalizing the surrounding environment, It aims at providing the manufacturing method of this.

Before the wash drying step, further comprising cutting the initial artificial stone composition, and after the washing drying step, water repelling the initial artificial stone composition and drying at 50 to 70 degrees effective.

Artificial stone composition of the present invention has a high strength and fast curing properties by adding a GNC environmental improver, as well as excellent antibacterial and deodorizing power, as well as sterilization, disinfection, purification, neutralization and alkalizing of the surrounding environment. And a large amount of far infrared rays can be emitted.

In order to achieve the above object, the artificial stone composition according to the first embodiment of the present invention is 20 to 76wt% Portland cement, 1 to 5wt% high strength admixture, 20 to 50wt% sand and 3 to 25wt% GNC environmental improver It is produced by mixing in a known method at a temperature of 0 to 40 degrees. The artificial stone composition thus produced is used for artificial stone composition. That is, the artificial stone composition can produce a variety of artificial stone according to the type or use of artificial stone, for example, artificial tiles, non-slip artificial stone, fireproof doors, heads, pillars, seats, moldings, decorative stones, brackets, Balusters, pyeongseok and flats can be manufactured. In addition, it is also possible to manufacture a large number of objects of the same shape and size, such as brick using the artificial stone composition. Such artificial stone composition according to the present invention has an excellent effect of purifying, disinfecting and disinfecting the contaminated surrounding environment, and may have a beneficial effect on health due to antibacterial and deodorization as well as far-infrared emission.

As the main component cement, ordinary portland cement is used.

In another embodiment, the Portland cement is dicalcium silicate (2CaO.SiO ₂ ), tricalcium silicate (3CaOSiO ₂ ), calcium alumina silicate (CaOAl ₂ O ₃ .2SiO ₂ ) and gypsum (CaSO ₄ ). Portland-based cement can be used. In addition, the Portland cement is effective to use within the range of 20 to 76wt% based on the total artificial stone composition. Preferably portland cement can be used in the range of 32 to 68wt%. Of course, the present invention is not limited thereto, and the content of cement may be variously changed depending on the content of other elements to be added. And, the content of cement can be added or subtracted within the range of 10% in the above range as needed.

Here, when the content of the portland cement is smaller than the lower limit (20 wt%) of the above range, it is difficult to exhibit a certain physical strength. In addition, when the upper limit (76wt%) is larger than the other components are difficult to mix, there is a disadvantage that the tensile strength and the compressive strength is not constant.

1 to 5 wt% is added as the high-strength admixture. At this time, it is possible to increase the strength of the artificial stone produced by the artificial stone composition by using a high strength admixture. Moreover, the present invention can increase the strength of the composition, which can be weakened by the addition of a GNC environmental improver. At this time, the high strength admixture is preferably added 2 to 5wt%. And, the content of the high strength admixture may be added or subtracted within the range of 10% in the above range as necessary. At this time, if the content of the high strength admixture is smaller than the lower limit of the above range has a disadvantage that the strength of the composition is weakened. And when larger than an upper limit, there exists a problem that tensile strength becomes weak.

And sand adds 20-50 wt%. Preferably it is possible to add 25 to 45 wt%. The content of sand may be added or subtracted within the range of 10% in the above range if necessary. By mixing sand in this range it is possible to increase the strength of the composition and the bonding force between the elements. Here, when the content range of the sand is smaller than the lower limit, there is a disadvantage in that the bonding force between the elements is lowered, and in the case where the content of the sand is more than the upper limit of the content range, the bonding force is further reduced and thus easily broken.

Next, the GNC environmental improver adds 3 to 25 wt%. Preferably 5-20 wt% is added. Through this, as mentioned above, it is possible to create a pleasant environment due to antibacterial, deodorant and far-infrared emission as well as environmental cleanup. The content of the GNC environmental improver can be added or subtracted within the range of 10% in the above range as necessary.

Here, GNC (Green Natural Clean) is non-toxic strong alkali (pH 11.56 ~ 15.07), the specific gravity is 1.53. GNC Environmental Enhancer is an inorganic mineral made by ion and synthesis at high temperature, with 99.99% strong antibacterial and strong deodorizing power.

That is, the GNC environmental improver is excellent in antimicrobial activity and capable of removing heavy metals such as arsenic, cyanide, mercury, phenol, and hexavalent chromium, which can cause 99.9% of Shigella, E. coli, and E. coli. GNC environmental modifiers are environmental and biocompatible materials. In addition, the GNC environmental improver has a good deodorizing effect. Therefore, it is possible to remove various industrial odors, such as sewage terminal treatment plant, food waste, manure treatment plant, incinerator, waste landfill, barn odor contaminant treatment plant, and leather factory.

And, the GNC environmental modifier emits far infrared (91.4%) and emits a phenomenal anion of 612 ^ION / cc.

In addition, the addition of the GNC environmental improver increases the removal efficiency of TVOC (total volatile organic compounds) and formaldehyde, thereby suppressing TVOC and formaldehyde generation in the artificial composition.

These GNC environmental modifiers can restore the destroyed environment and nature.

Such a GNC environmental improvement material can be produced by various methods.

Examples GNC the work environment improvement agent is silver nitrate (AgNo ₃₎ 3~5wt%, yeomhwageum (Aucl ₃₎ 3~5wt%, borax _{(Na 2 B 4 O 7)} 10~20wt%, sodium carbonate (NaCo ₃₎ 30~40wt% , Sodium peroxide (Na ₂ O ₂ ) 20 ~ 30wt%, and salt is an improving agent obtained by melting and cooling at 840 ℃ or more after cooling.

In the above silver nitrate is ionized in water to precipitate the silver has a sterilization, disinfection effect. It is neutral in itself and can neutralize and purify the surrounding environment.

Gold chloride is also ionized in water to precipitate gold, which also disinfects and disinfects. The reason for using gold chloride here is that the use of gold chloride rather than nitrate alone can have a synergistic effect of disinfection and disinfection. The amount of addition does not need to use a large amount of expensive substances because the effect of sterilization and disinfection is less than the above addition range, and the same or similar effect is obtained above.

Borax itself is alkaline, weakening or neutralizing the environment. Below the added amount, the action is weak and above, it may be a strong alkaline of the surrounding environment, rather, may cause harm to plant growth.

Sodium carbonate has a good effect of purification and washing. It softens, purifies and purifies the surrounding environment. In addition, the softening and refining action is less than the above added amount, and becomes strong alkaline above.

Sodium peroxide is hydrolyzed in water to produce caustic soda, which weakens or neutralizes the polluted environment.

In addition, GNC environmental improvers include 3-5 wt% silver nitrate, 3-5 wt% gold chloride, 10-20 wt% borax, 30-40 wt% potassium carbonate (K ₂ CO ₃ ), potassium citrate (C ₆ H ₅ K ₃ O ₇ ) 15-20 wt% and 25-35 wt% sodium metasilicate (Na ₂ SiO ₃ ).

In addition, GNC environmental improvers include 15-60 wt% of sodium metasilicate, 20-70 wt% of potassium carbonate, 1-4 wt% of potassium citrate, 1-3 wt% of borax, 0.03-0.04 wt% of nitric acid, and 0.03-0.04 wt of gold chloride. Contains% Here, 10 to 60 wt% per white may be further included.

Sodium meta silicate (Na ₂ SiO ₃ ) is an alkali builder that increases hardness and alkalinity so that the required amount of calcium carbonate can be dissolved sufficiently. It neutralizes fat and keeps it odorless. It promotes interfacial activity and increases the penetration and sterilization effect of microorganisms. At this time, the use of sodium metasilicate below the above range reduces the effect of the role, and if exceeding the above range can cause irritation to the skin, mucous membranes or eyes of the human body or animal, it is recommended to use within the above range desirable.

Potassium carbonate (K ₂ CO ₃ ) is an inexpensive alkaline disinfectant in the form of white powder, and serves to disinfect and remove viruses and bacteria that cause odor or transmit diseases. If the disinfecting effect is reduced and it exceeds the above range, it may irritate the skin, mucous membranes, eyes, etc. of the human body or animal, and therefore, it is preferable to use within the above-mentioned range.

Potassium citrate (C ₆ H ₅ K ₃ O ₇ ), together with potassium carbonate, increases the hardness as potassium is ionized, increases its disinfection effect by its sterilization action, prevents corrosion of building substrates, The use of potassium and sodium metasilicate acts as a pH adjuster that inhibits excessive alkalinization of the composition. At this time, the use of the above-mentioned range is insignificant, the above-described effect is insignificant, and when used in excess of the above range, the effect is insignificant compared to the amount of excess used, rather it does not sufficiently dissolve, so that the problem may occur that the composition becomes cloudy. It is preferable to use within the range.

Borax (Borex; Na ₂ B ₄ O ₇ ) plays a role in sterilization and antiseptic, disinfecting microorganisms that decompose organic wastes or preserving organic wastes to prevent decay. It serves to prevent the odor due to the use of less than the above range can not achieve the above-described effect, if used over the above range because it is not sufficiently dissolved and precipitates, the composition may be turbid, within the above-mentioned range Preference is given to using at.

Silver nitrate (AgNO ₃ ) and gold chloride (AuCl) are the components themselves are ionized in water to precipitate silver and gold to decompose and sterilize sterilization and odor, which aids in disinfection and deodorization. In particular, it is desirable to use the two components in combination to obtain synergistic effects of disinfection and deodorization. In this case, when each of these is less than the above-mentioned range, the above-mentioned effect is insignificant, and when it is used beyond the above-mentioned range, the effect is insignificant compared to the usage amount of the additive, and the manufacturing cost does not need to be increased by using a large amount of expensive materials. .

In addition, sugar is a nitrogen compound or sulfur-containing compound that causes odors by promoting the activity of microorganisms that ferment organic matters in odor-producing places such as barns, landfills, sanitary treatment plants, sewage treatment plants, agricultural and fisheries markets, and food factories. It inhibits the production of and serves to remove its odor. At this time, the use of less than the above range is because the effect is reduced, if used in excess of the range rather than promoting the decay bacteria may cause a problem that causes more odor.

According to the test results of the Korea Building Materials Testing Institute, all of these GNC environmental improvement materials were found to emit 0.918 at 5-20 ㎛ and radiation energy (W / ㎡) of 3.70 × 10 ² . Sterilize, disinfect, cleanse and purify the surrounding environment. As described above, it is possible to purify the contaminated surrounding environment by synergism by the respective actions of the respective substances.

The GNC environmental modifiers of the above-described composition are very similar in their properties and effects, and the anion release amount, bacterial reduction rate and deodorization rate are the same within the error range (± 5%).

Such a method for manufacturing various artificial stones based on the artificial stone composition of the present invention can be variously manufactured according to the type and use of artificial stone, for example, artificial tiles, bricks, non-slip artificial stone and interior and exterior materials of various buildings (fire doors) , Heads, columns, seats, moldings, decorative stones, brackets, balusters, flat plates, etc.).

Hereinafter, an embodiment of a method of manufacturing various artificial stones of the present invention will be described in detail. However, the scope of the present invention is not limited thereto. Reference examples are examples of artificial stone using the artificial stone composition of the present invention.

In one embodiment, Portland cement, high strength admixture, sand and GNC environmental modifier in the above-described content ranges are mixed at a temperature of 20 degrees. At this time, the mixing ratio of the water / cement is changed from 0.1 to 0.55 in the kneading machine and injected into the mold for natural curing.

Of course, the present invention is not limited thereto, and the artificial stone may be manufactured using the artificial stone composition through various manufacturing methods. For example, a curing process can be performed.

In addition, the following describes a manufacturing method according to a modification of such an artificial stone composition.

First, the Portland cement, the high strength admixture, sand and the GNC environmental improver in the above-described content range are mixed.

The mixture thus mixed is mixed with water and then mold-filled. At this time, it is effective to mix 10 to 20 wt% of water to 80 to 90 wt% of the mixture. Here, the shape of the mold is not limited, and various shapes are possible. This is because artificial stone of various shapes can be manufactured according to the manufacture of the mold. Of course, it is effective to manufacture in the form of a square plate for convenience of production. The curing is then cured through curing and drying. This produces an initial artificial stone composition. Then, a demolding process of separating the dried mixture (ie, the initial artificial stone composition) from the mold is performed. Then, the surface of the initial artificial stone composition prepared in the mold shape is polished. For example, the front and back surfaces of the initial artificial stone composition produced in the shape of a square plate are polished. This improves surface roughness. The initial artificial stone composition is then cut to the desired size. Through such a cutting process, it is possible to produce an artificial stone composition of the desired size.

Then, the cut artificial stone composition is washed and dried. Next, a water repellent treatment is performed using a water repellent body. This prevents foreign matter from adhering to the surface. Then, it is dried at a temperature of about 50 to 70 degrees to complete the artificial stone composition of the present embodiment. The drying may be carried out at this temperature to completely remove the water remaining in the composition.

In addition, another modification is possible with the manufacturing method of the artificial stone composition of a present Example.

Another modification is described as follows.

First, a mixture of the Portland cement, the high-strength admixture, the sand, and the GNC environmental improver mixture in the above-described content range is performed. The mixture is then filled into a mold. The mixture is then cured and dried to cure the mixture. This produces an initial artificial stone composition. Then, a demolding process of separating the dried mixture (ie, the initial artificial stone composition) from the mold is performed. Subsequently, the initial artificial stone composition surface prepared in the mold shape is shortened. At this time, it is effective that the size of the short ball is 0.5 to 1.5mm. Through such a shorting treatment, surface properties can be improved. Subsequently, debris is removed through a brush. The initial artificial stone composition is then cut to the desired size. Through such a cutting process, it is possible to produce an artificial stone composition of the desired size.

Then, the cut artificial stone composition is washed and dried. Next, a water repellent treatment is performed using a water repellent body. This prevents foreign matter from adhering to the surface. Then, it is dried at a temperature of about 50 to 70 degrees to complete the artificial stone composition of the present embodiment.

As described above, the method of preparing the artificial stone composition of the present embodiment may be variously limited.
