Description

Multi-functional artificial marble composition, method of producing the same, and multi-functional artificial marble using the same

The present invention relates to a multifunctional artificial marble composition, a method for producing the same, and a multifunctional artificial marble using the same,

It is an object of the present invention to provide a multifunctional artificial marble composition,

A method for producing a multi-functional artificial marble composition,

Artificial marble for interior finishing of buildings, artificial marble of natural stone texture, artificial marble of sound-absorbing function, artificial marble of insulating warm-keeping condensation-preventing function, humidity control deodorization Far infrared ray irradiation Performance multi-functional artificial marble.

The present invention aims to reproduce the texture, function and characteristics of natural marble or natural stone. Another object of the present invention is to provide a multifunctional artificial marble composition having a function of sound absorption performance, ventilation, fire safety, humidity control, deodorization, far-infrared radiation, heat insulation, heat insulation and dew condensation prevention, Respectively.

More particularly, the present invention relates to an artificial marble composition comprising chaff flakes, Expanded Vermiculite, and mica flakes as main materials, wherein the shape, layer structure, color, reflection light and texture of natural materials are used, A composition for applying functional properties to a composition is provided.

In particular, the artificial marble texture of a natural texture is realized by forming a laminated flaky cross-sectional structure using a rice husk as a flake shape, and a breathable artificial marble composition is provided by using a lamellar structure and a fibrous structure of a flake, Structure, a fibrous structure and a bubble cell structure to form a breathable crosslinked framework in the composition to provide a multifunctional performance.

The use of artificial marble or artificial stone is continuously increasing in the field of interior materials for architectural materials, interior decorations, decorative decorations, and remodeling.

The use of artificial marble artificial stone continues to increase due to the social environment that prevents the natural environment from beating due to mining of stone and the lack of supply due to the demand of natural stone natural marble. In addition, the use of artificial marble is continuously increasing because the homogeneous physical properties, durability, uniform color, uniform pattern, and processability in a certain form related to the quality of marble are limited.

In addition, it is more difficult to combine patterns and colors by mining the same marble if the corners are damaged and some of the lost parts are not conservative.

Another problem is the excessive weight of natural marble, which may provide secondary damage due to increased construction costs of the building, increased transportation installation costs, natural disasters such as earthquakes, and falling marble weights in the event of a fire.

Another disadvantage of natural marble is that it breaks easily and breaks the broken surface.

Therefore, in the present invention, the above-mentioned disadvantages of natural marble or stone are improved and means for reproducing the texture color function of natural marble or stone are also provided. Accordingly, it is desired to provide a multifunctional artificial marble composition in which various functions are added to artificial marble.

The superiority of natural marble to stone is in the beautiful color texture functionality of natural materials. The color and texture are the natural beauty of various kinds of rocks depending on the constitution conditions of the rocks. Most rocks emit far-infrared rays that are beneficial to the human body.

Accordingly, the artificial marble composition of the present invention is also provided with a structure in which beneficial far-infrared rays are radiated, and also to provide a multifunctional artificial marble composition or multifunctional artificial marble useful for a building space. In order to increase the far infrared ray emission rate, materials with high far infrared ray emission rate were selected as the main material, and chaff flakes, expanded vermiculite and mica flakes were suitable as mixing materials. The far infrared emissivity of vermiculite was 0.91 ~ 0.93, the rice husk was 0.85 ~ 0.90, and the mica flake was 0.92 ~ 0.94.

Far infrared rays have been shown to be able to provide biological activation effects as revealed by various theories and various experiments.

Therefore, in the present invention, as a material for reproducing the texture and functional characteristics of natural marble or natural stone, it is widely distributed in nature and is lightweight material. It is collected as open-air mineral and has a low cost "vermiculite" The "mica flakes", which have a texture closer to that of the mineral, are widely distributed in sedimentary minerals as well as "mica flakes" with excellent gloss and durability.

In the present invention, a multifunctional artificial marble composition using a flour flake, expanded vermiculite, and mica flakes and a technique relating to a multifunction artificial marble using the same are shown.

Such an artificial marble composition exhibits the texture of natural marble to provide a multifunctional artificial marble interior material capable of replacing expensive natural marble. Other functions include sound absorption performance, ventilation, fire safety, humidity control, deodorization, far-infrared radiation, and prevention of adiabatic thermal insulation condensation.

It is the natural stone and natural marble that has been used for the longest time in the history of mankind and the most important building material in modern architecture. Natural marble is priced according to the rare value of color and pattern, and it shows various color pattern texture depending on the kind of rock.

Natural minerals are often lost in order to mine expensive natural marbles, and mining and processing processes result in energy loss and price increases.

Despite the availability of many synthetic materials due to the development of science and technology, the demand for natural materials is increasing. This is a limitation of the material industry, which can not provide a suitable synthetic material to replace the texture, functionality and beauty of natural materials.

As seen in the history of architecture, interior and exterior finishes and decorative materials of important buildings are made of expensive natural materials. Natural marble, Onyx, jade, and rare metal minerals made of various rocks are also used as decorative materials.

The value of natural materials in the building decorative materials sector will increase further in line with the economic logic of demand and supply, which will lead to higher prices.

In Korea, imports of natural marble continue to increase, and imports of artificial marble of various textures are also increasing.

Therefore, in the present invention, vermiculite minerals which are relatively widely distributed in mineral resources and are easily collected from open-pit mines and are supplied at low cost and in various colors, rice husk flakes processed as agricultural by-products, rice hull flakes processed with mica, The present invention also provides a synthetic marble composition of natural marble texture and artificial marble of sound absorption function.

However, expanded vermiculite has a very weak layered structure and has disadvantages that it breaks and peels off even in contact or weak impact.

This is because the expanded vermiculite is composed of clay minerals with low hardness and is vulnerable to moisture, and the earthworm-like expansion process, which is laminated with lamellae, is structured such that the layered laminate is easily broken, and when pressed by hand, it breaks weakly and is separated into flakes and fine powders Very weak structure material.

We also provide a means for improving these disadvantages.

As a means for solving the disadvantages, the present invention has been able to achieve a constitution of improving the vulnerable layered structure of the expanded vermiculite and adding the multifunctionality to the expanded vermiculite of the fragile flaky structure by using the flour flake and the mica flake as the main mixed material .

Thus, a solid structure or a laminated structure having a sound layered structure and breathable sound absorbing performance was formed.

The rice husk flakes are plants having a very high mineral content.

The mineral content of most plants is about 1-2%. The mineral content of rice is about 11 ~ 25%, and 75 ~ 95% of rice minerals is silica. The content of silica in the rice husk is 11%, and the content of silica in the husk is 15 ~ 23%.

In the above, the artificial marble composition of the present invention has the object of providing a configuration in which beneficial far-infrared rays are radiated. Therefore, we chose one of the most suitable organic fibrous materials (0.85-0.90) that has the highest far infrared ray emission rate as one of the main materials. Using the shape of rice husk flakes, the use of organic fibers constituting rice hulls, Of artificial marble.

It is also suitable as vegetable fiber which increases sound absorption performance in artificial marble composition. The amount of flame retardant used in the rice husk flakes could be reduced because of the silica and minerals, which are incombustible materials contained in the rice hulls.

These properties of rice hulls are not suitable for composting process and are difficult to compost. However, such characteristics are excellent in durability and have a stable chemical structure and are used as characteristics more suitable for the present invention.

Therefore, the present invention is characterized by the use of this characteristic of the rice husk flakes and the following experiments are conducted using these characteristics to provide desirable results.

The structure of the rice is brown with rice husk, Palea and Lemma, and has a concave pear shape. The outer rice is broader than the inner rice and the inner rice is narrow.

The rice husk is a by-product which accounts for 18 ~ 22% of the rice weight, and the domestic annual production of the rice husk is approximately 1.5 million tons, reaching about 50 million tons worldwide and stable supply during the cultivation period, Friendly business that is economically inexpensive.

Further, the artificial marble composition of the present invention uses mica flakes as an additive main material. Within the artificial marble composition, the mica flakes add mica flakes for the purpose of improving the functionality of the composition, improving durability and decorating. It is a layered silicate mineral similar to the vermiculite used as the main material.

Therefore, the present invention attempts to form a solid layered structure and a breathable laminate structure using mica flakes as an additive material.

The artificial marble composition provided with this structure can be applied to the wall and ceiling of the building, and it is possible to apply it to the wall and ceiling of the building. According to the structure of the building, the field construction and molding can be performed according to the curved surface (wave shape surface) And this configuration can provide a seamlessly connected face.

In addition, functional artificial marbles of various sizes can be supplied in factories equipped with production facilities.

The method of field construction and manufacturing method of artificial marble plate in the factory can be carried out by methods such as laying, spraying, putty, plastering, filling, etc. Especially, when the artificial marble plate is manufactured in the factory, a mold is manufactured according to the product standard, , A process of filling the artificial marble composition, a drying and curing process, a cutting process, and a surface sanding process.

The thickness of the functional artificial marble and the functional artificial marble composition are approximately 5 mm to 50 mm depending on the purpose of use.

Korean Patent No. 10-1016424 discloses "a method for producing artificial marble containing amethyst and vermiculite ". This is an artificial marble composition in which pores in a composition are sprayed by adding a defoaming agent to a composition for forming a primary base layer and a secondary base layer. Such a composition is formed into a structure in which the open pores are closed, and the use of the composition as a sound absorbing material is unsuitable.

≪

Korean Patent No. 10-1133931 discloses an incombustible sound absorber and a method for manufacturing the incombustible sound absorber. The incombustible sound absorber includes a pretreatment step of coating expended vermiculite with sodium silicate once, drying and coating twice, but this method is not suitable for field work .

This method is also a vermiculite plate produced by a limited production method which is produced under the condition of factory production facility. In addition, the method of coating expanding vermiculite with sodium silicate is a method in which a siliceous soda coating (water glass coating) So that the open pores are reduced, so that the sound absorbing performance is deteriorated.

≪ Prior Art 3 &

Korean Patent No. 10-0710618 discloses a "composite material using a rice husk and a manufacturing method thereof ". This is an example of a rice hull board manufactured by immersing rice hulls in sodium hydroxide and silane, drying and mixing biodegradable synthetic resin to produce high heat at 200 ° C. and a pressure of 3 tons. This is also a method of manufacturing a rice hull plate produced by a limited production method which is produced under the condition of factory production facilities and is produced by mixing biodegradable synthetic resin and compressing at high temperature and high pressure so that the opened sound absorbing pores are closed. Also, such a blend composition is not suitable for expressing the texture of natural marble or stone.

Another domestic patent publication No. 10-2012-0019822 discloses an artificial marble of a granite pattern by kneading a compound having different colors, but the composition of the artificial marble is limited to the use of ordinary marble because no open sound- .

As another example, Japanese Patent No. 1019970772865 discloses "a method for producing an artificial stone composition and artificial stone ". This is an artificial stone in which 15% or less of a resin component is mixed with an inorganic fine particle component and compression molding is performed at a high temperature and a high pressure to complete the surface polishing process. This is an artificial marble composition having a compressive strength of 1400 Kgf / cm 2, a specific gravity of 2.29 and a water absorption rate of 0.13, and is an artificial marble composition in which sound absorbing pores are not formed due to properties similar to water-

In addition to the above-mentioned prior arts, structures that complement the weak physical properties of expanded vermiculite have been introduced in the industry. Another example is a mixture of expanded vermiculite and expanding pearlite, which is coated with water-binding adhesive and compression-molded at high temperature and high pressure. However, when the cross-sectional structure of the material is observed, And a problem of blocking the air-permeable layered structure has arisen. Therefore, these vermiculite plates were not suitable as sound absorbing materials.

In addition, when the expanded vermiculite is added as lightweight aggregate in the refractory coating industry, there is a problem that the layered structure pores of the expanded expanded vermiculite are partially broken during the wet mixing process and the operation of the spraying equipment. It is a disadvantage that expanded vermiculite is composed of clay minerals with low hardness, and is particularly susceptible to moisture, which breaks easily during the wet mixing process and operation of the spraying equipment.

The most disadvantage of expanded vermiculite is the inorganic material produced by plastic expansion process at high temperature, but it is weakly broken when pressed by hand, separated from bedded vermiculite flakes, and it is used only for limited purposes because it is powdered with fine powder.

Therefore, the present invention improves these disadvantages of the expanded vermiculite and provides a configuration for forming open pores, and also adds a multifunctional performance.

In order to explain the invention in detail, the present invention has been explained by dividing expanded vermiculite, rice flour and mica flakes into main components of artificial marble composition,

The unit packing method may be divided into the artificial marble composition according to the intended use and the intended use, and the artificial marble composition may be provided, which is classified according to the mixing ratio of the main material and the sub ingredient constituting the artificial marble composition and the particle size and color of the compound material.

The liquid composition may be supplied in a sealed package, and the composition of the dry package may be supplied in a moisture-proof package.

The dry packed composition is a dry mixed composition comprising powder mixtures and flake mixtures. The dry packaged composition is prepared by dry blending according to the blending ratio of the artificial marble composition, and is supplied in a moisture-proof package and used at a place where the blended water is added in an amount of 180 to 220 parts by weight And an artificial marble composition used by mixing with a mixer may be provided.

Since the composition supplied in a liquid sealed package is an aqueous liquid phase, it may be unsuitable in the winter season, and the method of supplying the moisture-proof package of dry blending can reduce the packaging cost and the distribution cost.

In the method of producing the artificial marble composition supplied as the liquid-phase sealed package, the mixing water and the foaming agent are supplied to the mixing and dispersing wet mixer tank to measure the "foaming agent dispersion ", and the rotation speed of the stirring blades in the mixer tank is 50 to 500 RPM At a high speed of 1000 to 5000 RPM at a low speed of 1 to 5 rpm to prepare "Foaming Water"

The raw material mixture mixture in powder form is supplied to a mixing and dispersing wet mixer tank provided with the above-mentioned "bubble liquid ", and the rotation speed of the stirring blades is mixed at 50 to 3000 RPM to produce air cells of" A third step of forming a slurry of sub-particles dispersed three-dimensionally and having an increased volume;

And then adding an adhesive binder to the slurry of the main material to complete mixing and dispersion.

As another method for producing an artificial marble composition to be fed in a dry blended state,

A powder mixture is prepared by supplying an inorganic filler, a flame retardant, a thickening adhesive, an anti-settling agent, an antibacterial preservative, a functional plant particle and a powdery foaming agent and an adhesive binder of a powder as a material to a dry powder mixer, (a) a step (a) of feeding the mixture to a center mixer;

A method of manufacturing an artificial marble composition in which an artificial marble composition produced in the state of powder in the state of Step 2a is divided into dry blending conditions by dividing and expressing the artificial marble composition according to the blending ratio for each use and the particle size and color of the blending material Can be provided.

The moisture-proof packaging composition to be supplied in the dry blended state is a dry blend composition comprising powder mixtures and flake mixtures. The blended water is added in a mixing ratio of 180 to 220 parts by weight in accordance with the blending ratio, The artificial marble composition used can be provided.

The artificial marble composition of the present invention may be provided on the surface of a building or may be provided with an artificial marble plate material in a plant having a production facility.

The thickness of the artificial marble composition is varied depending on the purpose of use, but is about 5 to 50 mm.

The mixing water is clean water having relatively low salinity (ppm) and hardness (water hardness), a suitable salt ion concentration is 150 ppm or less, and soft water is suitable.

Hard water or water with a high salt concentration is not suitable. Such water inhibits the formation of bubbles in the composition and deteriorates the sustainability and stability of the foam foam. Therefore, the volume of the artificial marble composition is decreased and the sound absorption porosity is decreased. Element.

The usable amount of the artificial marble composition "mixing water" supplied as the liquid-phase sealed package is 180 to 220 parts by weight, and when the amount is less than 180 parts by weight, the viscosity of the composition is excessively high and workability is inadequate, do. When the amount is more than 220 parts by weight, the viscosity is too low, resulting in inadequate workability, delay of drying time, and further increase of shrinkage of drying. Suitably 190 to 210 parts by weight.

As used herein, "blended water" is clean water that meets the above conditions.

In the above-mentioned blending composition, the usable blending amount of the foaming agent is 0.15 to 1.5 parts by weight. When the amount of the foaming agent is less than 0.15 part by weight, when the artificial marble is used as a sound absorbing material, the formation of the open pores is insufficient, so that it is not sufficient as a functional artificial marble for sound absorption purposes. If the addition amount of the foaming agent is more than 1.5 parts by weight, the open pores become excessive, which is unsuitable for bass sound absorption, and the structural bonding force and adhesion force are reduced. The preferable amount is 0.6 to 0.9 part by weight, and may vary depending on the type of foaming agent.

For the sake of brevity, the term "foaming water" is used herein for the sake of brevity for the sake of brevity. This is done by adding a foaming agent to a clean blended water to prepare a foaming dispersion, feeding the prepared foaming dispersion to a stirring mixer tank, And the liquid phase in which the volume of the dispersion is increased by 20 to 80% by collecting and dispersing the air in the foaming agent dispersion is referred to as "foaming liquid ".

Therefore, the prepared liquid phase is referred to as a "foaming agent dispersion" by supplying 0.15 to 1.5 parts by weight of a foaming agent to 180 to 220 parts by weight of clean water for mixing, then air is supplied to the foaming agent dispersion or air is collected, % Of the liquid phase is referred to as "foaming liquid".

Various methods can be used to form the "foaming water"

Alternatively, the above-mentioned "foaming agent dispersion liquid" may be prepared by controlling a foaming foaming nozzle of general foam at a low pressure to a high pressure and passing through a bubble generating insulator pipe together with high-pressure air. Alternatively, a method may be employed in which the above bubble dispersion is supplied to a high-pressure injector and sprayed with air. As another method, an air injection nozzle is provided on the bottom surface of the mixer tank for stirring, and a prepared "foam dispersion liquid" is supplied to the mixer tank for stirring. A method of increasing the volume of the dispersion by rotating the mixer shaft at a high speed and adjusting the amount of air supplied through the nozzle and stirring the mixture is also possible.

In a technical construction for increasing the volume of the foaming agent dispersion,

The increase in the volume of the "foaming dispersion" is an increase in the amount of air in the dispersion, and also the increase in the volume of the composition in the composition preparation step is an increase in the air content in the liquid composition.

When the volume of the "foaming water" is increased to less than 20%, the air-permeable pores are insufficient, the mixing dispersion efficiency of the compounding materials is also decreased, and the shape of the compounding materials may be broken. When the volume of the "bubble liquid" is more than 80%, the air permeability increases and the sound absorption performance is further increased. However, the increase in the volume increases the cost of the sealed package and the cost of the logistics.

Accordingly, the volume increase of the foaming liquid is suitable from 40 to 60%, and the volume increase of the finished artificial marble composition is 30 to 50%, preferably 20 to 40% to be.

The volume change of the "bubble liquid" may vary depending on the blended quantity of the material and the main material, and the type of the blended material, and may vary depending on the mixed dispersion RPM, the mixer time, and the supply of air. Also, the increase in the volume of the "Foaming Water" may vary depending on the type and amount of foaming agent.

The composition in which the foaming agent is added here is a technical constitution that can provide various functionalities of the present invention.

By adding foaming agent in the composition to form foaming water, it is possible to make a foaming water composition in which the volume of the foaming liquid is increased by 20 to 80%, which increases the mixed surface area of the material and the main material, Thereby shortening the uniform dispersion and mixing processing time. The ball bearing action of the bubble balls dispersed in the composition is also provided with the function of minimizing the damage of the characteristic shape and the shape of the mixed materials.

Also, the bubble balls dispersed in the composition are distributed in a three-dimensional three-dimensional position between the mixed materials and form spaces composed of bubble balls. These air cells are evaporated by the evaporation of water during the drying and curing process of the applied composition, and the bumped cells are shrunk by the drying curing of the composition and a part of the space is reduced, Cells.

Such open-celled cells are uniformly distributed in the composition to form continuous open pores on the inner surface and the surface of the artificial marble, so that the sound-absorbing performance of the breathable structure is provided.

Therefore, the technical structure for diversifying the function of the artificial marble composition is,

In the process for producing an artificial marble composition,

The composition of the foaming liquid in which the volume of the foaming agent dispersion is increased by 20 to 80% and the constitution of the constituted "bubbling liquid" are the same as those of the continuum of air cells made of foaming balls The air cells are dispersed and distributed in a three-dimensional three-dimensional position among the mixed materials in the composition manufacturing process step, inducing the ball bearing action, being foamed by evaporation of water in the drying curing process of the installed composition, And forming open air gaps in the inner surface and the surface of the artificial marble by forming void cells (Cells) of a breathable structure continuous to the positions of the artificial marbles.

Therefore, a technical structure capable of forming fine air cells (cells) of such a breathable structure, which is provided in the composition,

"Foaming agent dispersion" is supplied or collected with air to form foaming balls to form a "foaming water" composed of air cells, and the above- And the air cells are dispersed and the volume of the air slurry is increased, and the main material and the adhesive binder are supplied to and mixed with the slurry of the formed slurry to prepare a synthetic marble composition in which the air cells are dispersed and the volume is increased by 30 to 50% .

The volume increase volume of the artificial marble composition in which the air cells are dispersed and the volume is increased by 30 to 50% is calculated as the volume of the total amount of materials to be mixed; Based on the increased volume.

The description of the technical structure for forming the above-mentioned void cells (Cells) is described as an example of a method for producing an artificial marble composition supplied as a liquid-tight closed package.

As the foaming agent usable in the present invention,

(Surfactant), vegetable surfactant, ester surfactant, sugar surfactant, natural surfactant (vegetable surfactant, soap), vegetable surfactant, vegetable surfactant, (Polyacrylate type polymeric polymer), mineral base foaming agent (compound of dodecyl benzene system, aluminum powder), animal base foaming agent (foaming agent of animal blood, casein, gelatin etc.) , Baking powder, synthetic saponin, saponin extracted from plants (non-saponin, quillaja quillaja saponin, soybean saponin, saponin saponin, etc.), sodium hydrogen carbonate, etc. These may be used singly or in combination .

The artificial marble composition supplied in the moisture-proof packaging state of the dry blend includes a powder foaming agent and the usable powder foaming agent is a foaming agent in which the foaming agent is powdered. Examples of powder foaming agents suitable for environmentally friendly conditions include Kiraya powder (quillaja tree bark powder or saponin extract powder), mushroom peel powder or peel extract powder (Sapindus mukorossi, saponin extract of peel powder of peel of soapberry tree) Saponin powder, and baking powder. Among these groups, a powder foaming agent which can be used alone or as a mixture of two or more kinds of powders can be used.

Particularly, Kira powder or mulberry peel powder can utilize antibacterial and germicidal effect and it is more suitable as natural eco-friendly material.

A suitable blending amount of the powder foaming agent for dry blending is 0.15 to 0.75 parts by weight.

The foaming agent composition increases the fluidity of the composition and improves the workability.

This principle is a function of the foam foam dispersed in the composition, since spherical bubble balls formed in the composition cause ball bearing action, thereby increasing the fluidity of the composition.

Also, it is possible to obtain thicker workability by reducing water volume.

The purpose of using the inorganic filler in the above materials is to use a filler, an auxiliary flame retardant function which is an advantage of an inorganic material, a porous lightweight structure, and a deodorizing and humidifying function formed of a functional cell structure.

Accordingly, the inorganic filler that can be used in the present invention is a light inorganic material formed from an open cell structure or an independent cell structure. Examples of the filler include diatomaceous earth powder, diatomaceous earth particles, natural zeolite powder, Natural zeolite particles, synthetic zeolite, ilite powder, ilite particles, bentonite, activated carbon, charcoal, chaff charcoal, aerogels, silica bubbles, glass bubbles, ceramic bubbles, shiras bubbles, calcined expanded perlite, Alumino silicate, hollow ceramic bubble, and the like.

Since the multifunctional artificial marble composition of the present invention is configured to provide various functions, selection of an inorganic filler is an important constitution.

Natural zeolite, diatomaceous earth, ilite, activated charcoal and charcoal are more suitable as the inorganic filler suitable for this purpose. They are excellent in the adsorption and deodorization performance of harmful substances and have more than 90% of adsorption and deodorization effect of ammonia formaldehyde. Further, since the antimicrobial activity, the far-infrared radiation, the anion release and the humidity control performance are excellent, various functions can be added to the artificial marble composition of the present invention.

In terms of shape, physical properties and surface area capable of estimating the adsorption / deodorization performance of harmful substances, the surface area of ilite is 80-150 m 2 / g, which is larger than the surface area of muscovite 60-100 m 2 / g. Also, Illight is a clay mineral, formed by weathering of mica and feldspar. The main material (expanded vermiculite, mica flake) of the present invention is also a clay mineral, and thus is one of the inorganic fillers suitable for the present invention because of similar color property texture.

The specific surface area may vary depending on the kind, but the natural zeolite is about 200-500 m 2 / g, the synthetic zeolite is about 800-900 m 2 / g, the activated carbon is about 800-1000 m 2 / g, the char is about 250-300 m 2 / g, Lt; 2 > / g.

Diatomite is a biogenic silica with over 2,000 gypsum skeletons and a perforated skeleton of microstructures with a gypsum size of 0.75 to 1,000 μm. These structures act as adsorptive decomposition of harmful substances. Diatomaceous earth also sucks moisture from pests and can be used for insecticidal purposes.

As another function, the colors of natural zeolite, diatomaceous earth and ilite particles (0.5 to 3 mm / # 7 to 35 mesh) are natural color particles such as ivory color, soft ivory color, beige color, Since it is supplied, it is suitable for composing natural texture to artificial marble. It has excellent workability due to softness of strength during surface sanding and natural after sanding.

Suitable particle sizes are 0.5 to 3 mm, more suitably 0.5 to 1.5 mm.

The powder may be used in the form of a powder or a powder. However, since the fine particles can act as a microstructure slurry for blocking air-permeable pores in the composition, when used in the form of a powder, the blending amount is set to 5 wt% or less, Or less.

The amount of the inorganic filler to be used is 1 to 5 parts by weight. When the amount is less than 1 part by weight, the filler and the functional purpose are insufficient. When the amount is 5 parts by weight or more, the amount of the thickener and binder is excessively increased, The shape and color of the flake pieces, the expanded vermiculite, and the mica flakes, which are the main ingredients of the flake, are unnecessarily concealed. Suitably 2 to 4 parts by weight

The object of the use of the flame retardant agent in the above-mentioned materials is to provide an artificial marble composition satisfying the conditions suitable for the fire safety standard inside the building.

Examples of the inorganic flame retardant which can be used include boric acid, zinc bicarbonate, borax, ammonium sulfate, thermally expansive graphite, magnesium hydroxide, aluminum hydroxide, silicate and the like.

These flame retardants may be used singly or in combination of two or more.

The use of a flame retardant is determined in consideration of durability and the effect of flame retardancy between the characteristic flame retardants of the material. The use of the flame retardant is compensated for by using two or more kinds of the flame retardant alone.

Therefore, flame retardant synergistic effect and durability of flame retardant are improved and improved by mixing certain amounts of phosphorus and inorganic flame retardants.

The phosphorus-based or inorganic-based flame retardant is characterized by a particle size of 50 to 700 mu m, and a comparatively safe flame retardant that does not generate a halogen-containing gas is suitable for the present invention.

When the phosphorus-containing flame retardant is contained in an amount of more than 8 parts by weight, the delay of the drying time and the flame-retarding cost are excessively increased. When the phosphorus-containing flame retardant is contained in an amount of less than 2 parts by weight, More preferable.

When the inorganic flame retardant is contained in an amount of 6 wt% or more, the sound absorbing performance is insufficient. When the inorganic flame retardant is used in an amount of 2 wt% or less, the flame retardant performance is insufficient. Therefore, the inorganic flame retardant is preferably used in an amount of 2 to 6 wt%, more preferably 3 to 5 wt%.

Therefore, it is preferable to use a phosphorus flame retardant and an inorganic flame retardant in combination, and thus the usable flame retardant is used in an amount of 2 to 10 parts by weight.

Boric acid, zinc borate, and borax are excellent in antimicrobial preservative preservation function and are more suitable for the present invention. In order to utilize the flame retardant properties and the additive functions of the materials according to the flame retardant materials and to use the complementary flame retardant effect, when using two or more kinds of blends, the flame retardant properties and the additional functions of the materials are used, And add-ons. Therefore, it is appropriate to use a mixture of two or more of these flame retardants.

In the present invention, the thickener and the pressure-sensitive adhesive are described in one category. For convenience, the pressure-sensitive adhesive is referred to as a pressure-sensitive adhesive.

The amount of the pressure-sensitive adhesive to be used is 1 to 5 parts by weight, and when the amount is 1 part by weight or less, the thick-tack adhesive property is insufficient. When the amount is 5 parts by weight or more, the drying time is excessively long and the sound- In addition, the amount of the pressure-sensitive adhesive which can be used varies depending on the material, and the amount of the pressure-sensitive adhesive to be used is 1 to 5 parts by weight.

Materials that can be used as pressure-sensitive adhesives include sodium alginate, agar, pectin, cellulosederivatives (CMC / carboxymethlcellulose, HPMC / hydroxy propyl methyl cellulose, natural cellulose fibers (Arbocel et al. Water gums, water glass, alginic acid propylene glycol, polyvinyl alcohol, bentonite, montmorillonite, loess, gluten, glucomannan, guar gum arabic gum, Carrageenan may be used singly or in combination of two or more. Suitably, carboxymethylcellulose (CMC), hydroxypropylmethylcellulose (HPMC) were more suitable as the cellulose derivative.

The purpose of using the precipitation inhibitor in the above-mentioned material is added for the purpose of improving the sedimentation of the artificial marble composition which is produced in a liquid phase and supplied in a sealed package, and for the purpose of improving workability.

The amount of the inorganic precipitation inhibitor which can be used in the precipitation inhibitor is 1 to 3 wt%. Less than 1 weight is insufficient in the effect of preventing precipitation, more than 3 weight is excessive, suitably 1.5 to 2.5 weight parts.

The amount of the organic precipitation inhibitor which can be used in the precipitation inhibitor is 0.1 to 0.3 parts by weight. Less than 0.1 weight is insufficient in the effect of preventing precipitation, 0.3 weight or more is excessive, suitably 0.12 to 0.2 weight part. In addition, since the sedimentation preventive performance differs depending on the material, the usable amount of the precipitation preventing agent is 0.1 to 3 parts by weight.

The purpose of use of the antimicrobial beads in the above-mentioned materials is added for the purpose of preventing fungi against moisture and preservation to prevent fungi and microorganism-induced deterioration.

Examples of the antibacterial agent that can be used in the present invention include antibacterial agents such as benzoic acid, sorbic acid, sodium nitrate, propionic acid, potassium hypophosphate, sodium hypochlorite, boric acid, borax, zinc borate, inorganic metal antimicrobial agent, phytoncide extract, charcoal, , Plant-derived flavonoids, plant-derived saponins, synthetic saponins, monoglycerides, cathechins, rosin powders, vinegar extracts, grapefruit extracts, Or more. The usable blending amount of the antibacterial agent is 0.05 to 2 parts by weight since the performance varies depending on the material.

Phytoncide extracts with antibacterial preservation and aromatherapy functions are more suitable. In the case of the phytoncide extract, the extract is extracted from the extract of the active ingredient to extract the active ingredient. Therefore, the phytoncide extract is more suitable because it exhibits an effective performance even with a small amount of the extract and has an aromatherapy function. However, in order to maintain the antibacterial preservation performance, it is more preferable to mix the inorganic antibacterial material. A suitable mixing amount of the phytoncide extract is 0.05 to 0.1 part by weight, and a suitable mixing amount of the inorganic antibacterial agent is 1 to 2 parts by weight.

Latex resin, rosin resin, starch, cellak, gelatin and casein are suitable as eco-friendly adhesive binders. The acryl-styrene copolymer resin and the water-soluble polyurethane resin have excellent water resistance and can be used in combination of two or more in order to further improve durability and water resistance.

The amount of the adhesive binder that can be used is 15 to 45 wt%. When the weight is less than 15 wt%, the adhesive strength is insufficient. When the weight is more than 45 wt%, the flame retardant performance is insufficient. And may vary depending on the solid content and type of adhesive. Durability Water resistance It depends on the purpose of use and therefore the usage amount is not limited, but a suitable amount of the liquid binder binder is suitably 30 to 40 weight, and a suitable amount of the powder adhesive binder is 15 to 25 weight.

Also, if durability and water resistance are to be increased, the performance of the adhesive binder increases proportionally. However, the flame retardant performance and sanding workability must be satisfied.

In the process for producing artificial marble composition, which is supplied in dry form in the present invention, an adhesive binder in the form of powder or powder is used because a liquid binder binder can not be used.

As the powdery adhesive binder usable for this purpose, a material supplied in the form of powder or powder from the above-mentioned adhesive binder can be used. The usable quantity of the powdery adhesive binder can be based on the solids content (solids weight) of the liquid binder, and the solids content of the liquid binder is approximately 40 to 60 wt. Therefore, the combined amounts of the liquid binders and the powder binders of the same kind are approximately 100 wt. 50 weight of powder.

The main materials of the artificial marble composition are chaff flakes made of flaked lumber by processing rice hulls, expanded vermiculite formed by firing vermiculite as a functional mica clay mineral, and mica flakes composed of a layered silicate mica mineral And is characterized by containing main ingredients.

In the artificial marble composition, the compounding amount of the main ingredients is characterized by an artificial marble composition composed of 10 to 40 parts by weight of a rice husk flake, 20 to 60 parts by weight of expanded vermiculite, and 2 to 20 parts by weight of a mica flake.

The disadvantage of the weak structural and physical properties of expanded vermiculite, which is one of the main ingredients,

As a clay mineral, it is a material that is supplied through a plastic expansion process. However, it is a weak material that is easily reduced to clay powder when rubbed by hand, and this characteristic is more vulnerable in liquid or aqueous liquid phase.

Therefore, the technical composition of the present invention is to improve the weak structural properties of expanded vermiculite.

The present invention uses a piece of rice flour as a solution to this.

In a configuration in which the rice husk flakes can increase the structural strength of the bond in the composition,

Since the expanded vermiculite is weak in layer structure and physical properties, the layered structure gradually peels and breaks and part becomes powdered according to the progress of mixing time and composition viscosity in mixing, mixing and dispersing process of wet. This is weighted as the mixing pressure and the thickening resistance increase in the mixing and slurry composition process.

In addition, the separated flaky or particle powders were a weak clay component and served to lower the structural strength.

The present invention is based on this weak structure of expanded vermiculite flakes or particles,

A three-dimensional cross-linking structure of a bridge structure that improves the bonding strength of expanded vermiculite by uniformly dispersing the horseshoe flakes formed with strong water-resistant durability and strong cell structure in a three-dimensional three-dimensional position between the expanded vermiculite flakes or particles A multi-functional artificial marble composition and a multi-functional artificial marble.

In the rice husk flakes used as the main material of the artificial marble composition,

The usable mixing quantity of the rice husk flakes is 10-40 wt%. Less than 10 parts by weight is insufficient in crosslinking strength, compressive strength and tensile strength, and more than 40 parts by weight is insufficient in natural marble texture. Suitably it is 15 to 35 weight.

In the construction in which the rice husks are processed into a flake-like flake to be used as a layered structure material or a crosslinked structural material,

In the present invention, a constitution using a silicic acid component contained in rice is also provided.

Rice is a silicate plant containing a large amount of silicic acid (SiOH ₄ ). The silicate is integrated into the epidermal and epidermal cell membranes of the rice tissue to increase the resistance to the control of water vaporization, resistance to insect pests, and increase the firmness and water resistance of the cell wall. Silica is one of the materials having a high far infrared ray emission rate (a large amount of far-infrared ray emitting material; zirconium Zr, titanium Ti, manganese Mn, iron Fe, silicic Si).

The silica content of the rice husk is approximately 11%, and the silica content of the husk is approximately 15 to 23%.

The far-infrared emissivity of the rice husk is about 0.85 to 0.90.

Rice husk is a fuel source that is unsuitable due to excessive silica content as described above, and is a material having a high ignition point. In the flammability test of the present invention, 20 to 50mesh of rice husk flakes; 20 ~ 50mesh of wood flour was tested for flammability under the same conditions. The flame retardancy of flour pieces was 50 ~ 70% lower than that of wood flour, and the burning delay time was 50 ~ 70% better than that of wood flour. It is also very suitable as an artificial marble mixed material expressing natural marble texture.

The rice flour flakes were able to reduce the amount of flame retardant used because of silica and minerals, which are incombustible materials contained in rice hulls. Therefore, the present invention is also characterized in that the silicate component contained in rice is used as a flame retardant auxiliary agent.

The present invention also features a structure in which a cross-linked pore-like cross-linked pore, which is laminated with a fibrous structure of a rice husk flake and a layered structure or a three-dimensional structure, is uniformly formed in the artificial marble composition to increase sound absorption performance.

The high mineral content of the rice husk is inadequate for the composting process and makes composting difficult. However, these characteristics are excellent in durability and have a stable chemical structure, and are used as characteristics more suitable for the present invention.

Rice husk is a fibrous bark that surrounds the surface of brown rice. Its size varies depending on the variety of rice, but its length is about 6 ~ 12mm and width is about 3mm. The present invention relates to a process for producing rice husk flakes (rice husk flake particle) prepared by screening fibrous membranes (rice hull, Palea, and outdoor Lemma) And is used as a breathable cross-linking material.

The rice hull is a complex lignocellulosic material, and its organic constitution is known as lignin 15.38%, cellulose 35.62% and hemicellulose 11.96% (Biotechnol Prog 2005. Saha BC )

When the rice husk is used as a raw material and subjected to a digestion process, rice husk fibers and natural silica can be obtained. In addition, lignin and hemicellulose remain in the digestion solution in which silica is separated.

The surface of the rice husk is a biomass which is coated with a silicon material and is composed of a lignocellulose composite structure and is resistant to corrosion.

Lignin is a natural compound made of a hydrophobic polymer, a hard natural compound that is difficult to decompose and forms a covalent bond with hemicellulose.

Therefore, the rice husk is a solid compound made of a lignocellulose composite material, and is an excellent biomass having water resistance and durability, and has also worked well for improving the water resistance and durability of the composition of the present invention.

Cellulose, hemicellulose, and lignin were more suitable as they constitute the plant cell tissue of the rice hull and more solidly constitute the crosslinking structure in the present sound absorbing composition. In particular, rice is a "silicate plant" composed of plant cells with excellent water resistance, and the rice husk flakes acted as flakes with excellent tensile strength, compressive strength, bending strength and water resistance.

Accordingly, when 10 to 40 weight of the flake slurry was mixed and dispersed in the composition of the present invention, the water resistance, durability, tensile strength, compressive strength and flexural strength were remarkably increased to provide a robust artificial marble composition.

Therefore, the present invention is characterized by exploiting this characteristic properties of the rice husk flakes, and experiments using these characteristics are given below to provide desirable results.

In the experimental results, the shape of the rice husk flakes was not affected by the wet mixing process of the artificial marble composition and the formation of the artificial marble, and the shape of the rice husk flakes was mostly not damaged, and was uniformly distributed between the crushed or peeled expanded vermiculite particles and the expanded vermiculite flakes, Structure, and found favorable results to improve the durability (bond strength, tensile strength, compressive strength, flexural strength) and water resistance of the expanded vermiculite.

This advantage is more advantageous when the rice husks are processed into 10 to 30 mesh flakes, and the lamellar structure of the thin flakes forms a three-dimensional bond structure between the flakes and powder of expanded vermiculite and forms a water resistant bridge An improved durability is provided.

Therefore, the rice husk flake is a lignocellulose composite material which is difficult to decompose, and is a natural plastic excellent in water resistance durability tensile strength compression strength bending strength. In the present application, the natural flaky flake is a structure in which the flaky flake is used as a layered structural member or a crosslinked structural member.

In addition, there are useful antioxidant components and various useful components in rice hulls, which are suitable as eco-friendly materials. Recently, methods for extracting these components have been disclosed.

In the structure of rice,

Rice is brown rice, which is a rice paddy in the form of rice hulls (Palea) and outer lemma (Lemma). It is in the form of a pear shaped outcrop, and the outer side is broader than the inner side and the inner side is narrow.

The concave pear shape has the same shape as brown rice and the inner and outer sides are composed of thin fibrous film which forms concave curved space.

In recent years, an apparatus (manufacturing facility) for processing rice husks into thin flakes and removing unevenness has been introduced and is supplied according to a mesh to be ordered. It has been attempted as a wood-added material or a synthetic wood-added material, but the amount thereof is not improved.

In an example of a method of processing rice hulls, which are the husks of brown rice, into thin flakes,

Rice husk is a fibrous film (wool) having a thickness of about 0.05 mm to 0.25 mm and excellent in elastic strength, tensile strength and water resistance. However, due to these characteristics, it is a material which is difficult to crush and grind.

Therefore, recently, a process for producing a rice husk flake by a method of cutting or crushing at a high temperature after drying has been carried out.

In the drying and high-temperature heating process, chaff flakes are produced and supplied in the industry by controlling the temperature so as not to be carbonized, sterilizing and removing foreign substances, and controlling the firing temperature so as to maintain the natural color or brownness of the rice husks.

With this process, a rice husk flake suitable for the present invention can be obtained, wherein the rice husk flake aspect is a non-carbonized flake, and the color of the flake is in the natural color of the rice husk or in brown.

The brown rice husks (rice husk) flakes produced in the above process have a thickness of about 0.05 mm to 0.15 mm, and the width (plane size of flake grain) is sieved according to a standard of 8 to 180 mesh, .

The size of the rice husk flakes usable in the present invention is 8 to 180 mesh, suitably 20 to 100 mesh, more suitably 20 to 50 mesh. The suitable size for forming the inner layer of artificial marble is 20 to 100 mesh, and the standard suitable for forming the surface layer of artificial marble is 20 to 50 mesh.

Also, depending on the purpose of use of the flour flake, various surface textures can be provided on the surface and the cross-section of the artificial marble by selecting the finely divided meshes. The flour flakes of 8 to 20mesh, the flour flakes of 20 to 30mesh, And the shape and characteristics of the flake are used. The flaky flake is preferably divided into a flake, a 50-60 mesh long rice flake, and a 80-100 mesh long rice flake.

Therefore, the rice husk flakes usable in the artificial marble composition of the present invention have a thickness of about 0.05 mm to 0.25 mm, a width (plane size of flake grain) of 8 to 180 mesh, Characterized in that it is subdivided into 8-20 meshes of rice husk flakes, 20-30 meshes of rice husk flakes, 30-40 meshes of rice husk flakes, 50-60 meshes of rice husk flakes and 80-100mesh of rice husk flakes, Lt; / RTI >

The edge shape of the periphery of the front rear face of the rice husk flakes produced by this method is similar to that of the expanded flour and mica flakes because the fibrous bodies of the organic fibers are not visible when observed with naked eyes It worked very well for composition of natural marble texture composition.

Therefore, the rice husk flakes used in the present invention are produced by cutting and crushing the shape of a rice hull consisting of concave pear-shaped palea and lemma at a high temperature to produce flake particles, passing the flake particles It is characterized by a piece of rice flour ready for selection by size.

In the process of manufacturing the flakes, the inner and outer edges of the rice husks are cut and crushed at high temperature to form flat flakes, and the long fibrous bodies of needles or unnecessary foreign substances are removed and sorted in the processing, will be.

Therefore, the embodiment of the rice husk flakes used in the present invention does not show the shape of the organic fiber body on the composition mixed with the flakes of expanded zeolite, mica, and the appearance of the mineral flake, Thereby providing a composition that provides a marble composition.

Such a configuration is possible because the processed hanger flakes have a thickness, a horizontal and vertical shape, a width, a color, and a specific gravity similar to the flaky and mica flakes of expanded vermiculite, As a main ingredient of the present invention.

As another function of the rice flour flake, the organic fiber structure strengthened the cross-linking structure in the present artificial marble composition and increased open pores, resulting in improved air permeability and sound absorption performance

Therefore, the composition of the artificial marble composition of the present invention is,

By using the phosphorus flake thin film-containing silicate component, the far-infrared radiation performance, the organic fiber structure, the crosslinking structure formation in the composition, the formation of sound absorption structure of continuous open pores, the shape of lamellae, the compressive strength, the elastic strength, the tensile strength, Characterized in that the improvement of durability of the marble and the multifunctional characteristics are provided.

The heat insulation performance of rice hulls is approximately 0.045 to 0.06 kcal / mh ° C.

There are more than 40,000 kinds of rice varieties in the world, some of which are cultivated. It can be classified into long grains, medium grains, and short grains depending on the length and width of the grains.

In general, rice grown in Korea is medium-sized, and its outer size is about 6-7mm in length and 3mm in width.

When the rice husk (rice husk) is observed under a microscope, a fibrous hull-like epidermis is observed. These shells (rice hulls) are elliptical thin films of up to 20% of the weight of rice. Thickness of the thin films is about 0.05mm to 0.25mm and may vary depending on the rice cultivars and growth conditions. In the present invention, the thin film is processed and chaff flakes selected by size are used as a main material.

The thickness of the rice husk flakes produced by processing the rice husks (thin film) is about 0.05 mm to 0.25 mm, and the width and width are selectively produced according to the mesh scale. The shape of the rice husk flakes is a polygonal thin film, and the mesh size that can be produced is 8 to 300 mesh, and the standard that can be used in the present invention is 8 to 180 mesh.

The processed rice husk flakes were similar in shape and color to expanded expanded vermiculite, so they were suitable for use as the main material together with expanded vermiculite.

In addition, processed lumber and lignin and hemicellulose components were intact, which contributed to improvement of durability and bonding strength of artificial marble composition.

Throughout the specification, the term "rice flour flake"

Since rice husk has been processed into flaky material, the term "rice husk flake" has been used for convenience and the "rice husk flake" suitable for the present invention has been described throughout the specification.

In the expanded vermiculite used as a main material of the artificial marble composition,

The usable mixing quantity of expanded vermiculite is 20 to 60 wt. Less than 20 wt.% Of natural marble texture is insufficient, and 60 wt.% Is insufficient in adhesive strength and compressive strength. Suitably it is 30 to 50 weight.

However, the specific gravity of expanded vermiculite is heavier when the particle size is smaller, the specific gravity is lighter when the particle size is larger, and the proper mixing amount may be different because of the plastic expansion characteristics of the raw material and the vermiculate area.

Vermiculite is a clay minerals containing three kinds of water, water absorption, interlayer number and crystal number. When it is heated by a sudden high heat, water in the layer of vermiculite is vaporized by steam, pressure is generated, pressure is released, and it expands and becomes expanded vermiculite. The vermiculite is a stratified structure mineral formed of flakes showing gold, reddish brown, brown, light brown, gray, and silver reflected light as alteration function minerals of gold mica or biotite.

The present invention is characterized by the use of the natural color of the expanded vermiculite, the reflected light of the thin flakes, the layered structure, and the flake shape.

In particular, vermiculite, which is produced by the transformation of gold mica, muscovite and biotite, exhibits a beautiful color of pearl luster, so that it is intended to be used for decorative design expression of the artificial marble composition of the present invention.

During the sintering (1100 ℃), expanded vermiculite is a sterile clean material. It expands to 6 ~ 20 times and forms small layered spaces with open structure, so it has characteristics such as sound absorption, insulation, insulation, ventilation and buffering.

These structural characteristics exhibit performance such as formation of air-permeable pores, adsorption and deodorization performance, shock absorbing and buffering action, endothermic extinguishing agent (material for fire evacuation), insulation, and humidity control function. In addition, the physical properties of far infrared rays, formaldehyde adsorption, sick house syndrome improvement effect.

The vermiculite is a layered clay mineral produced by weathering or hydrothermal alteration of mica. The modified mica contained in the expanded vermiculite is in the form of a layered pore structure and a continuous flake shape of various colors of gloss and the flakes exhibit pearly luster or mica luster.

Therefore, the artificial marble composition of the present invention provides a structure that uses a layered pore structure formed in expanded vermiculite as sound absorption, heat insulation, thermal insulation, ventilation structure, and uses pearl luster, mica shine and flake shape of expanded vermiculous stone flakes as artificial marble design material / RTI >

Expanded vermiculite has a very weak layered structure and has a disadvantage that it breaks and peels off even when it comes in touch or weak impact.

This is because the expanded vermiculite is composed of clay minerals with low hardness and is susceptible to moisture. In the process of forming an earthworm-like expansion which is superimposed by flakes in the process of vermiculite firing, the number of absorption, So that the layered laminate is easily broken, and when pressed by hand, it is broken down and pulverized into fine powder.

These disadvantages are that the open layer in the layer easily breaks in the wet mixing manufacturing process, the viscosity control process, the high pressure conveying process, the mixer process before the field work, and the spraying and pouring process, and a part thereof becomes a fine slurry, And the compressive strength and tensile strength were lowered.

As a means for solving this drawback,

As a constitution having rigid flakes between the expanded vermiculite pieces, the expanded vermiculite particles and the expanded vermiculite particles constituting the expanded vermiculite structure, the fragile layered structure of the expanded vermiculite could be improved by adding the horny flake pieces and the mica flak pieces.

Therefore, the present invention is characterized in that a hard layered structure and a breathable laminated structure are formed by using the flour pieces and the mica flakes together with the expanded vermiculite as a main material.

One of the important constituents of the present invention is a configuration for mimicking or reproducing the shape of the natural stone or natural marble.

Therefore, mica, which is a part of natural stone or natural marble, is used as a main material as means for accomplishing this purpose.

Mica exists in various forms in rocks and soils on Earth, and it exists in igneous rocks, sedimentary rocks, metamorphic rocks, clay minerals and soils.

In the case of sedimentary rock, the artificial marble is formed by depositing various inorganic and organic materials, and the artificial marble of the present invention is also composed of inorganic minerals and organic materials.

The presence of mica is present as Biotite, Muscovite, Sericite and mixed mica. Therefore, the mica flakes used in the present invention can be used as a main material, It is possible to imitate the shape texture color of the marble or to reproduce the shape.

In the mica flakes used as the main material of the artificial marble composition,

The usable mixing amount of the mica flakes is 2 to 20 wt. Less than 2 wt.% Of natural marble texture is insufficient, and 20 wt.% Or more leads to an excessive increase in material cost.

Suitable mixing amounts of mica flakes are varied depending on the purpose of use. For example, the mixing amount of mica flakes suitable as the "artificial marble composition for surface finishing" of the present invention is 10 to 20 parts by weight. When various colors, shapes, reflected light, glass gloss and pearl luster of mica are used, The quantity may vary.

Also, if the use of mica is to mimic or reproduce the shape texture color of natural stone or natural marble as described above, it should be blended in a quantity similar to mica contained in natural stone or marble. It may not be limited.

For other purposes, the mica flakes can be provided with an excellent durability property and a design characteristic, and can also provide a composition for increasing or decreasing the mixing amount depending on the intended use of the composition of the present invention.

Therefore, the mixing amount of the mica flakes suitable as the "artificial marble composition for surface finishing " shown below may be 10 to 20 parts by weight.

In the present invention, a layered silicate mineral with mica flakes having the most similar composition and shape to vermiculite was selected. This is a natural expression of the natural texture of expanded vermiculite and natural marble composition of artificial marble composition was also suitable for expression.

Mica is also known as mica and is a layered silicate mineral. The hardness is about 2.5 to 4, and the specific gravity is 2.7 to 3.2. There are muscovite, soda mica, biotite, gold mica, and Hongyunmo depending on the composition and properties. It usually forms a hexagonal crystal form. The most cleavage (flaky cleavage structure) of the mineral is complete, and the flake fragments are excellent in water resistance, fire resistance and elasticity.

Muscovite and sericite are a group of hydrated aluminum silicate minerals and have a white-yellow-gray light brown pale green and glass pearl luster and excellent fire resistance. In particular, the scale shine of the mica was suitable for the pearl luster design of the artificial marble composition. The functional properties of the mica are also used to improve the functionality of the composition, and its properties include far-infrared radiation, deodorization, antibacterial and anion release.

Therefore, the present invention can form a solid layered laminate structure using mica flakes as an additive main material.

Mica is a mica-type mineral and is different from vermiculite in that there is no interstory water. It is layered and has a perfect cleavage and thinly peeled.

The shape of Mica Flakes (Mica Scraps) is similar to that of modified mica flakes contained in expanded vermiculite, so it is suitable for mixed composition with expanded vermiculite and has natural harmony.

Pearl luster mica flakes are also available. Particularly, the various colors and shapes of the various reflective shines are well suited for the purpose of enhancing the decorative design value of the artificial marble composition.

The tensile strength, compressive strength, bending strength and water resistance of the mica flakes were also suitable for improving the durability and water resistance of the expanded vermiculite.

Accordingly, the present invention features a multifunctional artificial marble composition comprising mica flakes as a main material to improve the tensile strength, compressive strength and flexural strength of the composition, and to provide various colors and various reflective luster.

The artificial marble composition of the present invention may be provided with a "artificial marble composition dedicated to surface finishing" which forms a finish layer of the marble surface.

This is a finishing exclusive composition for finishing laminate or finishing laminate constituting the surface layer and the exposed surface of artificial marble.

The "artificial marble composition for surface finishing only" is a composition comprising the same process as the process for producing the artificial marble composition of the present invention. The composition is merely divided into the color, shape, An artificial marble composition is provided which is packaged and supplied as an artificial marble composition for screen finishing only.

In a purpose and construction having "artificial marble composition for surface finishing only"

The artificial marble composition for surface finishing is further provided with the object of maximizing the excellent physical properties and shape characteristics of the mica flakes and further increasing the durability and the refractory performance of the surface layer. Characterized in that the shape of the natural marble is reproduced in a color reflecting light and the distribution density of the mica flakes is further increased on the surface layer of the artificial marble to thereby provide the compressive strength, durability, water resistance, fire resistance and lamellar flake structure of the surface layer. Artificial marble composition "

In the construction of the artificial marble surface layer using "artificial marble composition exclusive for surface finishing " in the field production of artificial marble or a manufacturing process using a mold,

The thickness of the surface layer is 2 to 12 mm, preferably 3 to 9 mm.

The feature of this configuration is to provide a structure maximizing the excellent physical properties and design characteristics of the mica flake material,

"Artificial marble composition for surface finishing only" increases the mixing amount of mica flakes in the composition manufacturing process to further increase the dispersion and distribution density of mica flakes in the composition, thereby further increasing the compressive strength and durability of the surface layer, Which is characterized by using various colors and reflected light of flakes appearing in various colors depending on the material to be used, thin layered flake structure of scaly shape and fire resistance of fire-retardant performance more effectively.

Therefore, the mixing amount of the mica flakes suitable as the "artificial marble composition dedicated for surface finishing " in the mixing composition of the multifunctional artificial marble composition may be 10 to 20 parts by weight.

For convenience, the term "artificial marble composition for surface finishing"

Another object of the present invention is to provide artificial marble compositions which are divided into "artificial marble composition" and "artificial marble composition for surface finishing only "

The artificial marble composition constituting the backing layer has to be comparatively more excellent because it should be able to be applied with a thickness of 10 to 50 mm for the purpose of manufacturing the factory of multifunctional artificial marble or for the purpose of sound insulation of the low- Quot; artificial marble composition exclusively for surface finishing "constituting the surface layer is a composition more suitable for reproducing the reflected light of the shape and color of natural stone or natural marble, There is provided a surface layer which confinement further increases the distribution density of the mica flakes and constitutes a lamellar flake structure reinforcing durability and fire resistance.

Therefore, the surface layer of the artificial marble is provided with a high-density surface layer, and the back layer has a relatively lightweight inner layer with a relatively low density.

The object of such a construction is to provide a lightweight artificial marble for the purpose of increasing the use efficiency of the blended material and reducing the manufacturing cost.

Another object of the present invention is to provide a sound absorbing structure similar to that of a porous sound absorbing material, so that the structure of a lightweight, low density inner layer forming a continuous open structure cross-linking structure has a structure suitable for bending of a medium frequency sound, And a resonance sound absorption structure useful for bass sound absorption is provided by regulating a part of the air permeable pores and increasing the frictional resistance to the acoustic frequency of entering or exiting.

Such an acoustic structure is to provide a plate vibration absorbing structure according to the density difference of the double structure layer, and to provide a plate vibration absorbing structure with an inner layer having a low density and elasticity on the back surface of a dense surface layer.

The differentiated surface layer has a density higher than that of the back layer and is provided with a surface layer partially reducing the air permeable pores with respect to the back layer so that plate vibration energy of middle low frequency sound transferred from the surface layer is absorbed and dissipated in the elastic back layer. It can feature multi-functional artificial marble of sound-absorbing construction.

In the sound absorption principle, the structure using the plate vibration absorption is used as the sound absorption method in the middle and low range, and since the sound pressure is larger as the wavelength is long, the plate vibration absorption efficiency becomes higher. Therefore, the present invention also includes a sound-absorbing condition in which the wavelength is long and low.

The means for controlling the partial reduction of the air-permeable pores in the surface layer is possible by a method of reducing the mixing amount of the foaming agent in the composition manufacturing process. The means for further increasing the density on the surface layer can be a method of increasing the distribution density of the mica flakes in the composition manufacturing process, a method of using a highly dense compounded material, or a method of pressing the surface layer.

Wherein the adhesive layer comprises a natural latex binder, a synthetic latex, a synthetic latex, and a synthetic latex, wherein the backing layer has a property of absorbing and dissipating plate vibration energy of middle to low frequency sound, A binder, and a urethane binder.

The multifunctional artificial marble of the present invention has a structure similar to the sanding or wax-polished surface of natural marble and is characterized in that the surface of the artificial marble is subjected to a sanding process or a wax polishing process in the manufacturing process or the field- .

In a purpose and a method for performing a sanding process on the surface of a multi-functional artificial marble,

The artificial marble of the present invention should be used as a surface finishing material for a building, and should exhibit similar appearance to the surface of natural marble or natural stone, so that the surface sanding or surface designing process is selectively performed.

The color texture of the rock surface varies depending on the type of rock, including igneous rocks, sedimentary rocks, and metamorphic rocks.

The methods of surface treatment of stone include flame treatment, roughing, fine cutting, roughing, chiseling, carving, water grinding, sheet cutting, natural facings, cutting, and composite processing.

The natural marble finishes of the buildings are generally supplied with marble finishes of various designs by surface processes such as water-grinding sanding finishes, wax-gloss finishes, glazed surface finishes and burner finishes.

Therefore, in the artificial marble manufacturing process or field installation process of the present invention, some surface designs that can be expressed by the composition are possible, and similar surface designs include a sanding finish design, a wax glossy finish design, a rough finish surface finish, Natural surface design was possible.

As a method of performing a sanding process or a wax polishing process on the surface of artificial marble,

The surface on which the artificial marble composition is laid is subjected to a horizontal pressing process to form a uniform horizontal surface, firstly sanding the dried cured surface with 60 to 120 mash, then secondly sanding with 220 to 400 mesh, , A final sanding finish of 500-1500 mesh, followed by a coating of a wax polish and activating a polishing tool to form a polished surface.

This process enabled the surface design similar to the surface of natural marble or natural stone, especially the shape, color and texture of the surface became similar to the surface of rock or the surface of building stone.

In addition, the purpose of performing a sanding process on the surface is to increase the breathable pores of the surface, thereby increasing the sound absorption performance.

The reason why the artificial marble composition of the present invention can similarly show the shape, color, and texture of the stone surface is that the natural mineral material includes mica flakes and expanded vermiculite and chaff flakes similar in shape to mineral flakes And various surface processing methods.

The applied composition is limited to the surface and subjected to a horizontal pressing process to form a uniform horizontal surface, and the horizontal pressing process forms a laminate composed of flakes on the surface layer and forms a breathable layer structure, The shape color texture of the materials is characterized by a laminate shape of the rock layer or a shape similar to the surface of a building stone.

In the surface pressing step of the composition laid out above,

The method of applying the composition to the surface of the building or the surface of the building can be a plastering method and a spraying method. Especially, the surface to be sprayed is sprayed by using a trowel, a putty putting tool, a horizontal tool pressing plate, And a pressing process can be performed to form a uniform horizontal plane.

In the surface composition of a multifunctional artificial marble using a horizontal tool or a pressing horizontal tool, the horizontal traveling direction of the horizontal tool or the pressing horizontal tool is adhered or pressed onto the surface of the applied composition, and the end line of the traveling direction (3 ° ~ 30 ° apart from the surface) is 3 ° ~ 30 ° apart from the surface and proceeds horizontally in one direction. The horizontal process in which the irregularly laminated flakes form a uniform horizontal plane on the surface, To 5 times to form a horizontal laminate composed of flakes on the surface layer.

Other horizontal tools may be used and are not limited to the above example.

In the surface finishing method of a multi-functional artificial marble, as another method,

We can supply marble of various surface design such as artificial marble of surface spray finish, artificial marble of surface finishing finish, artificial marble of surface pattern finish, artificial marble of surface putty finish.

For example, the process of forming artificial marble with surface spraying finishing may be followed by a horizontal process following the installation of the composition, taking into account the color and particle size of the composition, and providing artificial marble with surface spraying finishes using a plaster spraying apparatus and a spray nozzle can do.

Artificial marbles with surface finishing finish can also provide artificial marbles with surface finishes using various plastering tools (interior plastering tools, resin plastering tools, shaping tools, etc.).

Artificial marble of surface finish can be provided with artificial marble with surface pattern finish by performing a horizontal process followed by a patterning process using a patterned tool (pattern roller, pattern plate, etc.).

The artificial marble of surface putty finish can be subjected to a horizontal process following the application of the composition and can be provided with a putty finish and a putty finish using a putty tool and a horizontal tool (plaster horizontal tool, putty horizontal tool) have.

The above-described surface finishing sanding process is also carried out by means of increasing the air-permeable pores of the artificial marble surface.

In the case where the materials to be mixed in the mixing process of the composition are fine powder, the mixed amount of fine powder is large, and the mixed amount of the inorganic curing agent (cement, gypsum, water glass) During the drying and curing process, the slurry of the fine powder is eluted to the surface together with the capillary action of moisture and forms a partially blocked dry film on the exposed surface, and a part of the barrier film is formed It is.

This film formation may cause a problem of decreasing the breathable pores of the artificial marble.

In the present invention, as a means for solving such a problem, a horizontal sanding process for removing the coating film of the surface layer can also be provided.

A method of performing a horizontal sanding process for removing a coating on a surface layer,

Alternatively, these pins may be attached to the rotating cylinder of the roller.

The method of using the perforated plate provided with a plurality of fins may be such that the perforation hole can be formed by repeatedly pressing and detaching the surface layer or the inner surface layer by hand,

In the artificial marble manufacturing process using a mold, a perforation hole can be formed by a method of pressing and desorption using a press, and a release liquid can be sprayed or applied to the perforation fin portion to facilitate desorption. Adjustment of the puncture rate can be achieved by adjusting the diameter of the pins.

The method of using the perforation roller provided with the fins is such that the fins are inserted and detached by forming a perforation hole by being pressed in contact with the surface layer or the inner surface layer of the artificial marble and proceeding in one plane direction, The rate can be adjusted.

This sound absorption configuration and the sound absorption control of the acoustic frequency are based on the Helmholtz resonance sound absorption technology and the porous sound absorption theory. When the perforation hole is enlarged and the perforation rate is increased, the sound absorption performance of the middle sound is increased, the perforation hole is made smaller, The sound absorption performance of the bass sound increases. In addition, when the thickness of artificial marble is increased, both the sound absorption performance of the middle and high sound quality and the sound absorption performance of the bass sound increase, so the sound absorption performance is approximately proportional to the thickness.

The use of 2 to 20% of the perforation holes is configured to increase or decrease depending on the intended use of the artificial marble and the degree of the air-permeable pores of the artificial marble.

In the present invention, the thickness of the multi-functional artificial marble suitable for sound absorption purposes can be approximately 10 to 50 mm.

The multifunctional artificial marble composition is characterized by a multifunctional artificial marble having a breathable structure formed by laying the above artificial marble composition on the surface or mold of the building at a thickness of 3 mm to 100 mm and forming a horizontal plane and drying and curing process.

A suitable installation thickness for laying on the building surface is 3 mm to 50 mm, more suitably 5 mm to 25 mm. If the thickness is made thin, the drying curing period can be shortened and the material cost can be lowered, but the installation thickness is adjusted according to purposes such as sound absorption performance or insulation performance.

The multi-functional artificial marble of the present invention may be provided with one to three layers of reinforcing mesh layers on the surface layer or the inner surface, and the weaving interval (mesh interval) of the usable reinforcing mesh is 4 to 12 mm.

If the weaving interval of the reinforcement mesh is less than 4 mm, the effect of reinforcement may be reduced, and if it is more than 12 mm, the reinforcement effect is insufficient. Since the size of the flaky particles is about 0.5 mm to 5 mm, the reinforcing mesh layer may function as a material separation layer when the mesh weaving interval is less than 4 mm, and therefore, a suitable mesh weaving interval is 5 mm to 8 mm.

The material of the reinforcement mesh is not limited, but a glass fiber weave mesh and a carbon fiber weave mesh which are safe to fire are more suitable.

Examples will be described below in detail.

Observations and surface observations of chaff flakes, expanded vermiculite, and cloud lumps in the examples were performed by visual observation (observation; observation of the shape color texture of the exposed surface, And a visual impression involving contact touching). However, for the detailed explanation, the observation was conducted in various ways (observation method: visual observation, magnifying glass, 10 times Scale Loupe, 30 times microscope, 100 times microscope observation)

As a result of observing the shapes of the expanded vermiculite dispersed in the composition during the preparation and execution of the composition, some of the expanded vermiculite forms were broken and pulverized in the process of manufacturing the sound absorbing composition and the field construction. The process of crushed and pulverized expanded vermiculite increased with increasing viscosity of the composition and increased with increasing mixing time.

These fine powders are formed as a coating film blocked on the surface of the remaining expanded persimmon in the composition. When the composition is laid, the coated film is formed by forming a coating film floating on the surface and mixed with the adhesive component, Breathable structure.

Therefore, the present invention improves such a problem and improves the incorporation of the chaff flake into the main material as a material having a shape similar to a mineral material.

The rice husk flakes are characterized in that the flake pieces are not broken in the composition and are uniformly dispersed in the composition and are distributed evenly around the expanded vermiculite and the damaged and detached expanded vermiculite particles to form a three-dimensional crosslinked structure and a breathable layered structure Thereby forming a layer structure.

The formation of such an open pore structure in the composition is accomplished by the action of bubble cell pores dispersed in the composition to form a three-dimensional bridged structure or layered structure by uniformly dispersing the pieces of rice husk flakes in the composition without breaking.

The formation of the open pore structure is accomplished by forming a three-dimensional layered structure around the expanded vermiculite, the expanded vermiculite slab, and the expanded vermiculite powder in the cross-linking process in which the foam film of the pore voids are dried and dried in the drying process after the composition is laid And crosslinked.

Such air-permeable pores form a breathable cross-linked structure composed of chaff flakes, expanded vermiculite, mica flakes and mixed compositions in the space where the moisture of the foam balls is evaporated to form a desirable sound-absorbing structure.
