Description

Heating tile with built-in carbon fiber heating wire and panel using the same {HEATING TILES USING CARBON FIBER AND PANELS USING THE SAME}

The present invention relates to a tile and a panel using the same, and more particularly, to a heating tile having a carbon fiber heating wire and a panel using the same.

In general, the most used method for floor heating is a hot water heating method in which a pipe is buried in a foundation floor and a mortar of cement is applied thereon. Conventionally, the pipe which is buried in the base floor mainly uses a copper pipe or a plastic-based pipe, but recently, an XL pipe having improved durability is used due to problems such as defects or leaks in the pipe.

However, the method of laying pipes is not only a problem of pipe defects or leaks, but there is a risk of freezing due to water in the pipes when not used for a long time in cold weather such as winter. Due to this, there is a problem in that the temperature of water rises to a certain temperature and the thermal efficiency is low because hot water must be circulated as a whole along the pipe.

In addition, when the pipe is buried, the pipe is buried on the base floor, the cement mortar is covered on the top, and then the flooring is performed. It must be used in parallel, and it takes an additional time to dry the cement mortar before the flooring work, which increases the time required for the overall process.

1 to 4, the heating tile 1 having a built-in carbon fiber heating wire according to the present invention is easy to construct on a slab, and it is possible to prevent the danger of freezing by removing risk factors of freezing. The heating tile 1 with a built-in carbon fiber heating wire may have a shape of a circle, a square, a rectangle, and a polygon, and the size may be selectively formed according to the size of the base 100. The heating tile 1 having a built-in carbon fiber heating wire may include a base 100, a carbon fiber heating wire 200, a heat diffusion plate 300, a horizontal member 400, and a flooring member 500.

The base 100 may be constructed on one side of a slab (base), and may be formed of a material similar or identical to the slab. The base 100 may be adhered with a strong adhesive force without a separate adhesive means during construction by being formed of a material similar or identical to the slab, and accordingly, may be firmly constructed on the slab.

Here, the material of the base 100 is not limited to a material similar or identical to that of the slab, but is made of polyurethane synthetic resin, epoxy resin, crete series (ocher, charcoal, jade, etc.), cement mortar, high strength mortar, super concrete, wood, stone , It can be prepared by mixing any one or at least two or more of clay.

In addition, the base 100 may be made of a non-slip type on one side or both sides, and a carbon fiber heating wire 200 may be laminated on the other side. The carbon fiber heating wire 200 laminated on the other surface of the base 100 may be compressed on the other surface of the base 100 by pressing when the base 100 is in a semi-dry state, and carbon fibers on the other surface of the base 100 After the heating wire 200 is mounted, the base 100 is applied to the other surface of the base 100 by the thickness of the carbon fiber heating wire 200, so that the top end of the carbon fiber heating wire 200 is the same height as the other surface of the base 100. Can be.

In addition, the base 100 may be formed to a predetermined height, it may be formed of any one of a rectangle, a circle and a polygon. The predetermined height of the base 100 may be thicker than the sum of the thicknesses of all the layers stacked on the top of the base 100 or thicker than the thickness of the horizontal member 400 stacked on the top of the heat diffusion plate 300. Accordingly, it may be easy for heat generated from the carbon fiber heating wire 200 to diffuse upward.

The carbon fiber heating wire 200 may be buried on the other surface of the base 100 and generate heat by receiving electric power. The carbon fiber heating wire 200 may be buried on the other surface of the base 100 through a pressing method when the base 100 is in a semi-dry state, and the carbon fiber heating wire 200 is mounted on the other surface of the base 100 After applying the base 100 material to the other surface of the base 100 as much as the thickness of the carbon fiber heating wire 200, the top end of the carbon fiber heating wire 200 is at the same height as the other surface of the base 100, so that the base 100 ) Can be buried on the other side. Accordingly, the carbon fiber heating wire 200 may be securely fixed to the other surface of the base 100, and both ends of the carbon fiber heating wire 200 may extend outside the base 100 and be connected to an external power supply line.

Here, although two methods are disclosed for a method of embedding the carbon fiber heating wire 200, the method is not limited thereto, and any method capable of embedding the carbon fiber heating wire on the other surface of the base 100 may be substituted.

The carbon fiber heating wire 200 may be formed of a carbon fiber heating wire cable, as shown in the drawings, but is not limited thereto, such as a carbon rod, a carbon fiber heating wire plate, a silicon carbon fiber heating wire cable, or the like. It may be formed by mixing any one or at least two or more.

The carbon fiber heating wire 200 may have a structure in which carbon fibers are coated on the outside of the alloy heating wire. The alloy heating wire may generate heat when a current is supplied as a resistor, and increase the thermal conductivity by the carbon fiber, thereby reducing power consumed in heating. In addition, the heat spreading plate 300 formed of a material having a high thermal conductivity is stacked on top of the carbon fiber heating wire 200 to rapidly diffuse heat generated from the carbon fiber heating wire 300 to the top.

In addition, the carbon fiber heating wire 200 may be replaced with a nanoalloy far infrared heating wire.

The nanoalloy far infrared heating wire may have a structure coated on the outside of the alloy heating wire with a far infrared emitting material such as germanium, helium, or tungsten having a high far infrared emission amount. Nano-alloy far-infrared rays are short-lived due to disconnection, which is a disadvantage of conventional heating wires, by reducing the far-infrared emission material coated with nano-alloys, and by reducing the strength and reducing the uniformity of resistance value, improving the semi-permanent lifespan, preventing the decrease in strength, ultra-fast heat generation, and Resistance value uniformity can have the effect of uniformity.

When the nano-alloy far infrared ray heating wire is supplied with current to the nanoalloy heating wire as a resistor, the far-infrared emitting material may be heated by heat generated from the alloy heating wire, and accordingly, the far-infrared emitting material may be heated to emit far infrared rays to the outside. Nano-alloy far-infrared rays emit far-infrared rays, which emit radiant heat at a higher temperature than the carbon fiber heating wires 200 are built in, so that the predetermined space can be uniformly heated and far-infrared rays into the human body through the high penetration power of far-infrared rays. This penetration can stabilize the body, such as fatigue and stress relief.

In addition, the nano-alloy far-infrared heating wire may be protectively coated on the outside of the far-infrared emitting material, whereby the far-infrared emitting material may be protected to further extend the life of the nano-alloy far-infrared heating wire. At this time, the protective coating may be formed of a Teflon material.

The heat spreading plate 300 may be stacked on top of the carbon fiber heating wire 200, and heat generated from the carbon fiber heating wire 200 may be diffused upward. The heat diffusion plate 300 may be formed in the same form as the base 100, and may be formed of a material having a high thermal conductivity such as copper plate and aluminum.

A plurality of holes 310 may be formed in the heat spreading plate 300, and a horizontal member 400 or a flooring material 500 may be introduced into the plurality of holes 310. The horizontal member 400 or the flooring member 500 may be firmly combined with the thermal diffusion plate 300 by introducing the horizontal member 400 or the flooring member 500 into the plurality of holes 310 formed in the thermal diffusion plate 300, , Accordingly, it is possible to prevent the horizontal member 400 or the floor member 500 from being separated from the thermal diffusion plate 300.

The horizontal member 400 may be selectively formed on the top of the heat spreading plate 300 according to the method of laminating the flooring 500, and the upper surface may be horizontally formed to evenly stack the flooring 500 on the top. When the flooring material 500 is directly applied to the top of the heat spreading plate 300, the horizontal material 400 may not be formed, and when the flooring material 500 is stacked on the heat spreading plate 300 in a manufactured state, the flooring material ( To stack 500) horizontally, a horizontal member 400 may be formed between the heat spreading plate 300 and the flooring material 500.

The horizontal material 400 may be applied to the top of the heat diffusion plate 300 as a liquid material, and may be formed by mixing one or more of mortars, concrete, and epoxy resin. In addition, the horizontal member 400 may be formed to a thickness sufficient to cover the carbon fiber heating wire 200, and when the horizontal member 400 is a liquid material, it is closed with the flooring 500 before curing and curing within 24 hours. It is desirable to do. The horizontal member 400 may be formed to have a thickness thinner than that of the base 100 so that heat can be spread smoothly to the upper portion, and may be formed of the same material as the floor material 500.

The flooring material 500 may be applied to the top of the heat spreading plate 300 or may be stacked on top of the horizontal material 400, and discharge heat generated from the carbon fiber heating wire 200 transferred through the heat spreading plate 300 to the surface. can do. Accordingly, the temperature of the flooring 500 rises to perform heating.

Flooring 500 is to be formed by selecting one of a variety of commonly used materials such as reinforced floor, steel floor, plywood, PVC, marble, ceramic, granite, terrazzo, deluxe, asbestos, porcelain, polishing, concrete, polyethylene, etc. It can be made of non-crete PU-MF material. The flooring material 500 may be selectively used in consideration of strength, hardness, heat resistance, cold resistance, flame retardancy, etc., and additionally may consider waterproofness, sterilization, foreign matter penetration, and human body harmlessness.

In addition, the flooring 500 according to the present invention may include 10 to 50 parts by weight of a reinforcing material, 1 to 10 parts by weight of an anti-slip agent, 1 to 10 parts by weight of a water repellent, and 1 to 5 parts by weight of a stabilizer based on 100 parts by weight of a thermoplastic polyurethane. have.

In the present invention, the thermoplastic polyurethane is generally a polyurethane polymer having a urethane structure continuously, and is composed of a soft segment portion and a hard segment portion, and is made of a soft foam, a rigid foam, a paint, and an adhesive. , Sealants, elastomers, fibers, plastics and other applications.

The polyurethane can control a wide range of properties according to the content of each segment, and the soft segment segment mainly uses polyol having a weight average molecular weight of 500 to 5,000 g / mol, and the rigid segment segment has an aromatic ring structure. It has a stiff structure by urethane bonds capable of hydrogen bonding with the diisocyanate possessed, and is affected by stiffness according to the type and molecular weight change of the isocyanate.

In the present invention, the polyol is a material that forms a soft segment of polyurethane, has a low melting point and a secondary transition temperature, and has a relatively high weight average molecular weight of 500 to 5,000, more preferably 1,000 to 3,000 g / mol. It means a molecular weight diol. In the present invention, it is possible to use both polyether-based, polyester-based and polycarbonate-based.

Examples of the polyether system include polytetramethylene ether glycol, polyethylene glycol, polypropylene glycol, polyoxyethylene ether glycol, polyoxypropylene ether glycol, polytetramethylene ether-co-3-methyl-tetramethylene ether glycol and poly Any one or two or more selected from tetramethylene ether-co-2,3-dimethyl-tetramethylene ether glycol can be used.

As the polyester type, for example, polyethylene adipate glycol, polybutylene adipate glycol, polyhexamethylene amipate glycol, polycaprolactone glycol, diol, for example ethylene glycol, 1,3-propane diol, 1,4 -Butane diol, 1,6-hexane diol, 2,2-dimethyl-1,3-propane diol, 3-methyl-1,5-pentane diol and mixtures thereof and dicarboxylic acids such as adipic acid , 1,9-nonanedioxane and 1,12-dodecanedioxane, and the like, or any one or more selected from hydroxy terminated reaction products.

Examples of the polycarbonate system include polybutylene carbonate glycol, polyhexamethylene carbonate glycol, polypentane-1,5-carbonate diol, polyhexane-1,6-carbonate diol, and the like. You can.

In the present invention, it is most preferable to use polytetramethylene ether glycol when considering the physical properties of the flooring material 500 to be produced. In addition, the weight average molecular weight may be 1,000 to 3,000 g / mol, preferably 1,500 to 2,000 g / mol.

More preferably, the polyol may have a hydroxyl value of 30 to 90 mg · KOH / g, more preferably 50 to 60 mg · KOH / g. If it is less than 30 mg · KOH / g, it is difficult to induce urethane bonds by reaction with isocyanate, and thus the molecular weight of polyurethane may be lowered. If it is more than 90 mg · KOH / g, gelation proceeds by rapid reaction to control the reaction. It can be difficult to do.

Also, the polyol may be added with a bio-polyol. The bio-polyol is a polyhydric alcohol produced based on renewable resources such as natural oils without using petroleum-based raw materials, and can be produced based on animal and vegetable oils, and includes polyether polyol, polyester polyol, vegetable oil polyol, and the like. You can.

The animal and vegetable oils may be natural oils, preferably vegetable oils. Examples of animal oils may include fish oil, cow oil, pork oil, sheep oil, and the like, and mixtures thereof. Meanwhile, examples of vegetable oils include sunflower seed oil, canola oil, palm oil, corn oil, cottonseed oil, rapeseed oil, linseed oil, safflower seed oil, oat oil, olive oil, palm oil, peanut oil, rapeseed oil, rice bran oil, flaxseed oil, sesame oil , Soybean oil, castor oil, etc., more typically, may mean soybean oil, castor oil, palm oil, and the like, but may also include mixtures thereof, but the present invention is not limited to the above-listed types.

For example, in the case of pizza horse oil, it is an oil obtained by squeezing a seed of castor bean (Rucinus communis). The oil contains about 45% of the seeds and has a higher oil content percentage than other seeds. The fats and oils have a triester (triglyceride) structure of fatty acids and glycerin as a whole. Castor oil is similarly characterized by about 90% of glycerin's triesters or fatty acids composed of ricinoleic acid. The rest may contain oleic acid, linoleic acid, and the like.

In the present invention, the bio-polyol may be prepared through a hydroxyl group addition (hydroxylate) reaction. For example, in the method for preparing the bio-polyol according to the present invention, ESO (epoxidized soybean oil), methanol, and formic acid are added to the reactor slowly while being sufficiently stirred while paying attention to heat generation in N ₂ purge conditions. The stirred mixture is heated and maintained at 40 to 80 ° C. for 6.5 to 13 hours under a hydroxylate reaction until the target has a target hydroxyl value. When the target hydroxyl value is reached, a reduced pressure reaction and solvent recovery are performed at 60 ° C. Thereafter, the solvent, unreacted raw materials and water may be removed through heating and high vacuum reaction at 120 ° C. for 5 hours to produce biopolyol.

In the present invention, the bio-polyol preferably has a hydroxyl value of 45 to 180 mg · KOH / g, and more preferably 50 to 80 mg · KOH / g. When the hydroxyl value is less than 45 mg · KOH / g, it is difficult to increase the molecular weight of the polyurethane, and when it is more than 180 mg · KOH / g, crosslinking is promoted by a rapid reaction during manufacture, so it is difficult to control the reaction.

In the present invention, when the bio-polyol is used in combination with a general polyol, it is preferable to mix the bio-polyol 5 to 7: 3 in the general polyol 3 to 5 weight ratio. In the above range, mechanical properties such as surface hardness and tensile strength may be secured, and if it is out of the above range, crosslinking is promoted due to a rapid reaction and excessive viscosity may increase, resulting in defects in the flooring 500 coating process.

A diol-based chain extender may be further added to the polyol separately. The diol-based chain extender acts as a chain extender that induces intermolecular bonds when the polyurethane is formed by reaction of a hydroxyl group (-OH) group located at the terminal. In general, when the amount is increased, the hardness of the polyurethane When increasing or decreasing the amount of use, hardness may decrease.

Examples of the diol-based chain extender are diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, butylene glycol, 1,3-butanediol, 1,4-butanediol, 2-methylpentanediol, 1,5 -Pentanediol, 1,6-hexanediol, hexylene glycol, neopentyl glycol, 4-cyclohexanedimethanol, trimethylol propane, pentaerythritol, and mixtures thereof. have.

The amount of the diol-based chain extender is not limited, and can be freely adjusted within a range that does not impair the physical properties of the present invention.

In the present invention, the diisocyanate is a material that forms a hard segment of the polyurethane to be produced, and is combined with a chain extender, which will be described later, to determine the chemical structure of the hard segment.

As the diisocyanate in the present invention, for example, p-phenylenediisocyanate, m-phenylenediisocyanate, 2,4-torylene diisocyanate, 2,6-torylene diisocyanate, 1,5-naphthalene diisocyanate, hexamethylene di Isocyanate, 4,4'-diphenylmethanediisocyanate, 4-methyl-1,3-phenylene diisocyanate, 1-isocyanato-4-[(4-isocyanatophenyl) methyl] benzene, 1 A mixture of -isocyanato-4-[(4-isocyanatophenyl) methyl] benzene and 1-isocyanato-2-[(4-isocyanatophenyl) methyl] benzene, 1,4 -Diisocyanatobenzene, 1,3-diisocyanatoxylylene, 1,4-diisocyanatoxylylene, 2,6-naphthalene diisocyanate, 5-isocyanato-1- (isocyane Itomethyl) -1,3,3-trimethylcyclohexane, 1,1'-methylenebis (4-isocyanatocyclohexane), 2,4-diisocyanato-1-methylcyclohex , 2,6-diisocyanato-1-methylcyclohexane, octahydro-1,5-naphthalene diisocyanate, 1,4-diisocyanatocyclohexane, bis (isocyanatomethyl) cyclohexane Any one or two or more of them may be used, and 4,4'-diphenylmethane diisocyanate is most preferable in view of reactivity with polyol and polymer properties.

The diisocyanate compound is preferably added in a mole ratio of 1.5 to 2.0 moles compared to 1 mole of polyol. If added less than 1.5 mol, the elastic fiber has excellent elongation but the strength may drop, and when added more than 2.0 mol, the strength is excellent but the elongation decreases, and the viscosity stability of the polymer may deteriorate.

In the present invention, the reinforcing material is included to increase the strength, heat resistance and durability of the flooring 500 and reduce manufacturing cost, such as tensile strength, tearing strength, breaking strength, etc. of the coating formed by coating the flooring 500 It can serve to improve mechanical properties.

In the present invention, it is preferable to use cotton fibers, hemp fibers and mother fibers natural fibers or glass fibers, carbon fibers, and the like. In particular, natural fibers have biodegradability and are more environmentally friendly than other reinforcing materials by absorbing greenhouse gases such as carbon dioxide.

In the present invention, the reinforcing material is more preferably mixed with hemp fiber, glass fiber, and carbon fiber, and most preferably hemp fiber with kenaf fiber, glass fiber, and carbon fiber.

In the present invention, the Kenaf ( Hibiscus cannabinus L. ) fiber is also called a hemp (洋 麻), is an herbaceous plant native to West Africa and is one of the world's three largest textile crops and is a plant resource for various bio materials. Is in the limelight. It is a natural fiber that has received the most attention in the field of green composite materials because it has a fast growth rate and absorbs carbon dioxide in the atmosphere relatively more than other natural fibers.

  The kenaf fiber has a cellulose content of about 60 to 70%, a lignin content of 10 to 20%, and a content of 20 to 25%, such as pentosan, to compare fiber content with hemp or jute. Because it is economical due to its short growth period, it has been studied in the United States as a jute substitute fiber since the 1940s.

Kenaf fiber is composed of cellulose and non-cellulose, such as pectin, hemicellulose, and lignin, like ordinary bast fibers. The kenaf fibers are easily dispersed in the mixture when compounding, and not only provide a reinforcing effect to the composition, but also contribute to improving the dimensional stability of the composition.

In the present invention, the glass fiber has a specific gravity, elongation, small diameter, and high tensile strength to impart mechanical properties to the flooring material 500, and has excellent surface properties such as weathering resistance, chemical resistance, and surface electrical resistance. Weatherability can be improved.

In addition, the carbon fiber is a fiber having a carbon content of 90% or more obtained by heating a precursor, which varies depending on the type of the precursor, such as a fan, pitch, rayon, heating conditions, and presence or absence of elongation. Compared to this, it has a higher tensile strength and a tensile elastic modulus, and can increase the heat resistance of the flooring 500 due to characteristics such as low thermal expansion coefficient and high chemical resistance.

The kenaf fibers, glass fibers and carbon fibers are good to limit the fineness and length to strengthen the physical properties of the composition by strengthening the entanglement between the fibers and fibers or between the fibers and the mixture. Specifically, the kenaf fiber, glass fiber, and carbon fiber has a fineness of 30 to 100 dtex, and preferably has a fiber length of 0.1 to 5 cm. When the fineness is less than 30 dtex, fracture may occur due to external force, and thus the tensile strength, tear strength, etc. of the entire composition or coating film may drop, and when it exceeds 100 dtex, the aspect ratio (single fiber length / single fiber diameter) becomes small. Mechanical properties such as tensile modulus may be reduced. In addition, when the fiber length is less than 0.1 cm, the hardness of the coating film may decrease and the abrasion resistance may decrease, and when it exceeds 5 cm, the miscibility with the composition decreases and the fibers located on the surface of the coating film deviate in large quantities when exposed to abrasion loads. can do.

In addition, in the present invention, the kenaf fibers may be used alone, but may be coated with one or more polymers on the surface in order to further increase the miscibility with the mixture and the mechanical properties of the composition.

In the present invention, the polymer may be more preferably polydopamine. The polydopamine is not only capable of self-polymerization at a constant pH range in which the dopamine monomer contains an alkyl group, but also possesses excellent chemical stability, and can be coated to 50 nm or less to provide good processability. In particular, dopamine has an advantage of using an eco-friendly and inexpensive distilled water-based buffer solution in place of an organic solvent that is expensive and harmful to the human body.

In the present invention, the polydopamine is not limited to a manufacturing method, but dopamine may be spontaneously polymerized in a state in which alcohols such as methanol and ethanol are mixed at pH 7 to 12, preferably at pH 8 to 10.

In the present invention, the polydopamine may be formed as a coating layer by impregnating the coating solution with natural fibers such as kenaf fibers for a certain period of time to form a coating solution by acting as a buffer solution. The impregnation method may be a variety of methods, such as a general immersion coating method, a pressure coating method, a spin coating method, a spray method or a roller coating method, and the present invention is not limited thereto.

In the present invention, the reinforcing material is preferably used by mixing hemp fiber, glass fiber and carbon fiber in a weight ratio of 1: 0.1 to 0.5: 0.1 to 0.5, respectively. In addition, the reinforcing material may contain 10 to 50 parts by weight compared to 100 parts by weight of the thermoplastic polyurethane in the total composition may be enhanced mechanical properties such as tensile strength, breaking strength.

In the present invention, the water repellent is to impart hydrophobicity to the composition to block the penetration of moisture and increase moisture resistance, and a silane or siloxane system may be used. Examples of these include isobutyl trimethoxysilane, isobutyl triethoxysilane, isooctyl trimethoxysilane, and isooctyl triethoxysilane, and these may be used in combination of one or two or more.

In the present invention, it is preferable to add 1 to 10 parts by weight based on 100 parts by weight of the thermoplastic polyurethane. When adding less than 1 part by weight, the effect of adding the water repellent agent is insufficient, and when adding more than 10 parts by weight, the chemical properties of the composition may deteriorate due to the miscibility of the composition due to excessive addition of the water repellent agent.

In the present invention, the stabilizer is intended to prevent oxidation or deformation or destruction of the composition from ultraviolet rays, and is a kind of plastic stabilizer.

Antioxidants in the present invention can be used for both primary and secondary antioxidants. Preferably, as a phenol, sulfur-containing phenol, bisphenol, polyphenol, etc., aromatic amine, phosphite, sulfur ester, and the like can be used. More preferably, it is preferable to use dibutyl hydroxy toluene (Butylated Hydroxy Toluene), nonylphenyl phosphite (Tris (nonylphenyl) phosphite), or the like.

In the present invention, the ultraviolet stabilizer may be used as both an ultraviolet absorber and a quencher, preferably benzophenone, benzotriazole, salicylate, cyanoacrylic, oxanilide, hindered amine (HALS) , Metal complex salt system and the like, and more preferably, TiO ₂ , HALS system is preferred.

In the present invention, the stabilizer is preferably added to 1 to 5 parts by weight based on 100 parts by weight of the thermoplastic polyurethane. When adding less than 1 part by weight, the effect of adding a stabilizer is insufficient, and when adding more than 5 parts by weight, the mechanical properties of the composition may be deteriorated.

In addition, the composition may further include any one or a plurality of metal oxides selected from copper, manganese, nickel, platinum, iron, rubidium, vanadium, gold, silver, tin, zinc, and bismuth.

The metal oxide is for more effectively improving the mechanical properties and chemical resistance of the flooring composition, and also acts as a kind of reinforcing material, and can further improve the scratch resistance by being involved in the moisture curing of isocyanate to be described later.

Examples of the metal oxide to the metal include copper, manganese, nickel, platinum, iron, rubidium, vanadium, gold, silver, tin, zinc, and bismuth. These may be used alone or in combination of two or more.

In the present invention, the metal oxide does not specify its manufacturing method and size, but is preferably manufactured by a sol-gel method, and can form a network structure having an average particle size of 20 to 200 nm.

In the present invention, the metal oxide is preferably added in an amount of 0.1 to 1 part by weight based on 100 parts by weight of the thermoplastic polyurethane. When adding less than 0.1 parts by weight, the mechanical properties may be deteriorated, and when adding more than 1 part by weight, the mechanical properties may be reduced by acting as impurities in the composition.

In addition, the flooring composition may further include a self-healing composition to further increase scratch resistance. Specifically, the self-healing composition may include a prepolymer having an isocyanate group.

In the present invention, the prepolymer has an isocyanate group having a fast curing rate in the presence of moisture. Especially when exposed to moisture in the atmosphere, the isocyanate group reacts with water to release carbon dioxide and form an amino group. The amino group thus formed reacts in series with the surrounding isocyanate groups to form a urea bond, and they rapidly cure to remove scratches.

In more detail, when a scratch occurs in the flooring 500, the isocyanate is filled into the depression area where the scratch occurs as it comes into contact with air, and at the same time, the reaction rate with moisture increases through metal oxides nearby. Self-healing properties can be expressed by conversion to a solid polymer.

However, it is important to block the isocyanate from moisture because it can quickly cure when it comes into contact with moisture in the air. Therefore, while maintaining the isocyanate in a liquid state, it is preferable to mix it in a composition in a fine capsule. Through this, when a scratch occurs after the construction of the flooring 500, the microcapsules contained in the flooring 500 are broken so that the liquid isocyanate flows out and reacts naturally.

In the present invention, the isocyanate is preferably a diphenylmethane diisocyanate prepolymer. The diisocyanate prepolymer reacts with moisture in the air to increase the crosslinking density, has excellent adhesion to a spherical flooring material, has good hardness and excellent durability.

The isocyanate does not limit the content of the isocyanate group (-NCO), but if the content of the isocyanate group is increased, flexibility and abrasion resistance of the coating film may be improved, but hardness may be deteriorated, so it is preferable to control the isocyanate. The content of the group is 5 to 20% by weight, preferably 10 to 15% by weight of 100% by weight of the total isocyanate.

In addition, the self-healing composition may further include a reactive single molecule as a chain extender in order to strengthen the bond between the isocyanate molecules. The chain extender is, for example, diols such as ethylene glycol, propylene glycol, 1,4-butanediol, 1,6-hexanediol, diethylene glycol, triols such as glycerin, trimethylolpropane, tetraols such as pentaerythritol, polyoxy Diamines such as propylenediamine, ethylenediamine, propylenediamine, butylenediamine, hexamethylenediamine, 1,4-cyclohexyldiamine, tetramethylpropylenediamine, tetramethylhexamethylenediamine, m-phenylenediamine, toluenediamine, diethanolamine , Any one or two or more selected from amino alcohols such as triethanolamine, and the like.

In the present invention, the self-healing composition is selected from inorganic materials including the isocyanate or the chain extender, such as melamine-formalin resin, urea-formalin resin, polyurethane resin and silica, titania, zirconia, alumina, zinc oxide nanoparticles, etc. It may be accommodated and provided inside a wall material including any one or more materials. In particular, in consideration of heat resistance and ease of encapsulation among the wall materials, melamine-formalin resin and urea-formalin resin are preferable.

The method for preparing the self-healing composition in the present invention is not limited. As an example, it may be manufactured by using a known in situ method, and will be described in detail as follows.

First, an aqueous emulsifier solution is prepared as a first step. Emulsifiers are very useful for improving the viscosity and particle size distribution of capsules. As the emulsifier in the present invention, alkali metal sulfates such as sodium dodecyl sulfate, alkali metal salts of fatty acids such as alkali metal salts of octadecanoic acid, anionic emulsifiers such as sodium dodecyl ether sulfate, anionic emulsifiers such as sodium dodecyl ether sulfate, and higher aliphatic hydrocarbons Cationic emulsifier, polyethylene glycol, polyoxyethylene alkyl ether, polyethylene oxide, polypropylene oxide, polyoxyethylene sorbitan monostearate, to which an amine halide, an alkyl tetraammonium salt, or an alkylpyridinium salt is bonded as a functional group of Non-ionic emulsifiers such as polyoxyethylene sorbitan tristearate and polyoxyethylene glyceryl monostearate may be used alone or in combination of two or more. The aqueous emulsifier solution can be obtained by adding conventional water such as emulsifier and distilled water to an emulsifier (Homomixer) and stirring at a temperature of 20 ° C to 40 ° C, and is usually prepared at a concentration of 1 to 15% by weight. If the amount of the emulsifier is less than 1% by weight, the emulsification is unstable and it is difficult to make emulsification of a desired particle size, and if it exceeds 15% by weight, the viscosity of the capsule slurry produced with economical problems may increase, and thus it may be difficult to use.

As a second step, an appropriate amount of isocyanate or chain extender to be used as an internal material of the capsule is added to the aqueous emulsifier solution prepared in the emulsifier, and the emulsifier rotates at a speed of 4,000 to 10,000 rpm between 20 and 40 ° C. The mixture was stirred at high speed for 60 minutes to prepare a fine-sized emulsion mixture.

In the third step, melamine-formalin or urea-formalin prepolymer is prepared by adding water to a separate reactor, adding melamine and formalin or urea and formalin and reacting at a temperature of 50 ° C to 70 ° C for 20 to 60 minutes.

As a fourth step, the melamine-formalin or urea-formalin prepolymer was added to the emulsifying mixture contained in the emulsifier and stirred for 1 hour to 2 hours at a speed of 200 to 1,000 rpm in the emulsifier rotation speed between 50 ° C and 70 ° C. While further proceeding the polymerization reaction to obtain a fine capsule slurry.

In the fifth step, the obtained fine capsule slurry is dried through a dryer such as a spray dryer to obtain a fine capsule.

In the present invention, the size of the microcapsules is preferably in the range of 0.01 to 100 μm in average particle size, preferably in the range of 0.1 to 10 μm. If the average particle diameter is less than 0.01㎛, the wall thickness of the microcapsules is not proportionally thin, so there is a fear that the self-healing effect will eventually decrease due to the small amount of self-healing material per weight of the fine capsule, and if the average particle diameter exceeds 100㎛ The surface roughness of 500 may be increased, and the microcapsules may deviate from the flooring 500.

In the present invention, the self-healing composition is preferably added to 1 to 10 parts by weight compared to 100 parts by weight of the polyurethane. When adding less than 1 part by weight, it is difficult to secure self-healing properties, and when adding more than 10 parts by weight, mechanical properties of the flooring material 500 may be deteriorated.

The flooring 500 according to the present invention may further include an additive containing at least one selected from the group consisting of lubricants, processing aids, colorants, and combinations thereof. In this case, it is preferable that the additives contain 0.1 to 10 parts by weight compared to 100 parts by weight of the polyurethane, and when two or more are added, it is preferable in terms of the effect and economic aspect of each additive to satisfy the above range.

Specifically, the lubricant may include stearic acid or rosin to increase the fluidity of the composition. In this case, the effect of reducing the processing temperature of the flooring material 500 and reducing the processing time can be achieved, and the workability of the manufacturing process of the flooring material 500 can be improved.

The processing aid is added to improve the processability and formability of the flooring 500, and may specifically include a methyl methacrylate (MMA) -based material, wherein the methyl methacrylate-based material has a weight average molecular weight About 100,000 to 3,000,000. When the single layer includes the processing aid, it is possible to shorten the melting time in the manufacturing process and improve the melt strength. In addition, by using the processing aid, the components of the single layer can be uniformly mixed, and consequently, the mechanical properties of the flooring 500 can be improved.

The colorant is for imparting color to the flooring 500, and preferably, a pigment or a disperse dye is used.

In addition, one or more of an anti-slip agent such as acrylic, rubber, silicone, and styrene may be applied to the surface of the constructed flooring 500, and more preferably, a styrene copolymer is used. This is to create a safe use environment by preventing slipping of workers.

The anti-slip agent used on the surface of the flooring material 500 is not limited to viscosity, and preferably, when the anti-slip agent is treated on the surface, a coefficient of slip resistance bar (CSRB) of 0.7 or more is more preferable. Preferably, CSRB is 0.7 to 2.0 or more.

In addition, the flooring 500 may further include at least two or more types of silica sands having different sizes to improve air permeability. Specifically, by including at least two types of silica sands having different sizes in the flooring 500, voids may be generated between the flooring 500, thereby improving the breathability of the flooring 500 after construction. I can do it.

In addition, the flooring 500 may further include a silver nano pigment for anion emission. Specifically, by containing the silver nano-pigment in the flooring material 500, anion can be released from the floor after construction, whereby air purification, sterilization, increased immunity, stabilization of autonomic nerves, insomnia relief, fatigue Recovery, pain relief, and mental stability.

The present invention includes a construction method of the flooring 500 using the composition for floor coating as described above. Specifically, the construction method of the flooring 500 may vary depending on the construction location, purpose, etc. of the flooring 500, but in general,

a) arranging and drying the construction surface;

b) forming a primer layer by applying a primer composition in which an epoxy primer and a solvent are mixed at a predetermined ratio on the construction surface;

c) applying a flooring composition comprising 10 to 50 parts by weight of a reinforcing material, 1 to 10 parts by weight of a water repellent and 1 to 5 parts by weight of a stabilizer to 100 parts by weight of the thermoplastic polyurethane on the surface of the primer layer; And

d) drying and curing the flooring composition;

It may include.

In the present invention, the construction surface may be typically composed of a concrete or asphalt structure or a mixture thereof.

It is preferable that the construction surface arrange impurities or irregularities before applying the primer layer. Specifically, it is good to spray water on the surface and planarize the surface with a grinder or the like. After the planarization is finished, it is good to dry the surface to remove residual moisture.

The primer layer is located on the top surface of the construction surface to improve adhesion between the flooring 500 and the construction surface, and is formed by curing the primer. Although the primer layer is not limited, acetone 1 to 10 wt%, xyl 25 to 40% by weight of ren, 20 to 35% by weight of toluene, 20 to 50% by weight of polyamide resin or epichlorohydrin-bisphenol A resin, and ethylene glycol monoethyl ether or 2,4,6-tris [(dimethylamino ) Methyl] It is preferable to form by coating a composition in which the epoxy-based primer containing 1 to 10% by weight of phenol and the diluent are mixed in a weight ratio of 1: 0.9 to 1.1.

The diluent may use a thinner for conventional paint, and it may be more preferable to contain 65 to 70% by weight of toluene and 1 to 10% by weight of solvent naphtha (petroleum, heavyarom) in the total composition. Such thinners are commercially available under the trade name of Ecoport 1000 Shinna from Samwha Paint Industry Co., Ltd.

The primer layer does not limit the formation thickness, and it is good to cure it after applying the primer composition to have a thickness of, for example, 1 to 5 mm. At this time, depending on the purpose of use of the flooring 500, it may be applied after arranging reinforcing materials such as glass fiber and wire before forming the primer layer.

Next, the flooring composition may be applied over the primer layer. At this time, the flooring composition includes 10 to 50 parts by weight of a reinforcing material, 1 to 10 parts by weight of an anti-slip agent, 1 to 10 parts by weight of a water repellent, and 1 to 5 parts by weight of a stabilizer, and metal oxide, etc. It may be further added as a filler or reinforcing material.

Since the flooring composition is fast-curing, it is good to mix and use the composition quickly. The process time and temperature are not limited, but the working time in the overall process is preferably performed within -10 ° C to 10 ° C within 1 hour, particularly within 40 minutes.

The flooring material 500 according to the present invention maximizes mechanical properties by including natural fibers as a reinforcing material, and at the same time uses vegetable natural fibers that are renewable resources to suppress the generation of harmful gases and is environmentally friendly. By further including a healing composition, it is possible to improve the scratch resistance and significantly increase the life of the flooring 500.
