Figure 2 is a cross-
3 is a photograph showing a state in which water is dropped on the upper surface of a floor board according to the first embodiment of the present invention

Hereinafter, the present invention will be described in more detail.

1 and 2 are a perspective view and a cross-sectional view of a preferred embodiment of the present invention. As shown in the drawings, the present invention provides a wood-based foamed substrate 100, a dimensionally stabilized layer 200 formed on the upper surface of the woody foam substrate 100, a printed pattern layer (not shown) formed on the upper surface of the dimensionally stabilized layer 200 A waterproof layer 400 formed on the upper surface of the printed pattern layer 300 and a topcoat layer 500 formed on the upper surface of the waterproof layer 400.

The woody foam substrate 100 is extrusion foam-molded at a high temperature and a high pressure with a molding mixture containing wood or wood fibers, a resin and a foaming agent. The molded mixture for molding the woody foam substrate 100 is a wood-plastic compound (WPC), preferably 35 to 55 parts by weight of wood or wood fibers, 35 to 65 parts by weight of a polyolefin resin, 0.5 to 2.0 parts by weight of a foaming agent.

If wood fibers or wood fibers are contained in an amount of less than 35 parts by weight, the woody foam substrate 100 has no feeling as a wood, while if it exceeds 55 parts by weight, the flexibility and bending strength of the woody foam substrate 100 are significantly reduced .

When the polyolefin-based resin is contained in an amount of less than 35 parts by weight, the bending strength of the wood-based foamed substrate 100 is lowered. When the amount of the polyolefin-based resin is more than 65 parts by weight, elasticity and restoring force of natural wood are lost.

Azodicarbonamide, which is a self-extinguishing and non-toxic stable substance, is used as the foaming agent. If the foaming agent is contained in an amount of less than 0.5 parts by weight, the woody foam substrate 100 is not foamed properly, and if it exceeds 2.0 parts by weight, the foam is excessively foamed, resulting in a problem of lowering the strength of the woody foam substrate 100.

It is a matter of course that conventional additives such as dispersants, lubricants, softeners, extenders and the like may be further included in the molding mixture.

The woody foam substrate 100 is formed by extrusion foaming a molding mixture having such a composition. The woody foam substrate 100 is formed in various sizes to have a thickness of about 6 to 8 mm.

Since the woody foam substrate 100 is formed by foam molding, the woody foam substrate 100 is lighter in weight, so that not only the handleability is improved, but also the heat insulating property is improved and also the sound absorbing property against the interlayer noise is obtained.

Preferably, as shown in the figure, the joining groove 102 and the coupling protrusion 104 are formed on both sides of the woody foam substrate 100 so that the floor board material can be easily and easily fitted. Therefore, the present invention is interconnected and assembled by a click system by the coupling groove 102 and the coupling projection 104. [

More specifically, the coupling groove 102 is formed to be recessed inward from one side of the woody foam substrate 100, and a downwardly concave locking groove 110 is formed in the bottom surface of the coupling groove 102.

The engaging projection 104 is formed on the other side of the woody foam substrate 100 and is inserted into the engaging groove 102 of the adjacent floor plate material. The engaging protrusion 120 to be inserted is protruded downward.

When the engaging protrusion 104 is inserted into the engaging groove 102, the engaging protrusion 104 is inserted into the engaging groove 102, and the engaging protrusion 104 is inserted into the engaging groove 102 of the adjacent floor plate. 110, the assembled state of the floor plate material is maintained, and the floorboard material does not fall off in the process of constructing the floor plate material.

2, the floor plate is tilted so that the end portion where the coupling groove 102 is formed faces upward, so that the coupling protrusion 120 is engaged with the coupling groove 102 of the adjacent floor plate, Lt; / RTI > In this way, the engaging protrusion 120 is easily engaged with the engaging groove 102 without being caught by the bottom surface of the engaging groove 102. Since the bottom surface of the coupling protrusion 104 does not protrude downward even when the bottom plate of the coupling protrusion 104 is inclined at the bottom surface of the coupling protrusion 104, Easily inserted.

On the other hand, the dimension stabilizing layer 200 stabilizes the numerical value of the woody foam substrate 100 to prevent the woody foam substrate 100 from being deformed in shape and size, such as being contracted or twisted by the external environment

The dimensionally stabilizing layer 200 is formed to a thickness of about 5 to 300 탆 by coating a stabilizing coating agent including a polyolefin resin and a stabilizer on the upper surface of the woody foam substrate 100.

The stabilizing agent acts to acetylate and esterify the hydroxyl groups present in the wood. The hydroxyl groups present in the acetylated and esterified woods by the stabilizing agent block the bonding with water molecules, thereby minimizing heat and moisture deformation .

As the stabilizer, an acid anhydride is used. Specifically, one type is selected from acetic anhydride, maleic anhydride, phthalic anhydride, and succinic anhydride.

In addition, the stabilizing coating agent further includes additives such as fillers, flame retardants and the like in addition to the solvent. As the solvent, a conventional organic solvent is used, and the filler is selected from among calcium carbonate, talc, titanium oxide, silica, glass powder and silicon dioxide, and the flame retardant is selected from phosphoric acid ester, halogen hydrocarbon, antimony oxide, aluminum hydroxide, .

Preferably, the stabilizing coating agent comprises 65 to 90 parts by weight of a polyolefin resin, 5 to 15 parts by weight of a stabilizer, 10 to 30 parts by weight of a solvent, 5 to 20 parts by weight of a filler and 5 to 15 parts by weight of a flame retardant, do.

The printed pattern layer 300 is formed by attaching a decor sheet. The decor sheet is a typical decor sheet on which a wooden pattern is transferred. Preferably, a decor sheet having a pattern transferred thereon is used for a TPU film having excellent durability.

The waterproof layer 400 is for imparting water resistance to the present invention, and is formed by adhering a waterproof film.

Preferably, the waterproof film comprises 20 to 80 parts by weight of an emulsion polymer of acrylic acid, dimethylaminoethyl acrylate, and acrylonitrile, 30 to 60 parts by weight of an aqueous dispersion of an epoxy resin, 100 parts by weight of acrylonitrile-butadiene 10 to 30 parts by weight of a copolymer and 16 to 30 parts by weight of tetraalkoxysilane.

The emulsion polymer is prepared by stirring 5 to 50% by weight of acrylic acid, 5 to 50% by weight of dimethylaminoethyl acrylate and 10 to 90% by weight of acrylonitrile with distilled water in a stirrer, emulsifying and adding a reaction initiator and an emulsifier .

The waterproof composition is prepared by first hydrolyzing tetraalkoxysilane in ethanol and dehydrating and condensing it to prepare a siloxane bond (-Si-O-Si-), and then adding the emulsion polymer and an aqueous dispersion of an epoxy resin, acrylonitrile- Butadiene copolymer, and the waterproofing composition is calendered to produce a waterproof film.

The waterproof film thus produced has a basic waterproof property by the aqueous dispersion of the emulsion polymer and the epoxy resin, and further has a high water resistance because the structure is densified by the siloxane bond of the tetraalkoxysilane.

Meanwhile, the top coating layer 500 is formed to improve the wear resistance of the floor board according to the present invention and to prevent aging of the product, and to have a thickness of about 5 to 300 μm by coating a finish coating agent.

Preferably, the finish coating agent comprises a UV-curable functional group-containing resin, a fluorine-based compound, an inorganic nanoparticle, a photoinitiator and a solvent.

The type of the UV-curable functional group-containing resin is not particularly limited as long as it is UV-curable, and a polyfunctional or monofunctional monomer or oligomer such as acrylates, methacrylates, and vinyls can be used.

The UV-curable functional group-containing resin is preferably contained in an amount of 70 to 85 parts by weight based on 100 parts by weight of the entire coating composition. When the UV-curable functional group-containing resin is contained in an amount of less than 70 parts by weight, the cross linking density of the resin is lowered and the hardness of the top coating layer 500 rapidly decreases. The abrasion resistance is improved, but the hardness is excessively increased, and the top coating layer 500 may be broken.

The fluorine-based compound increases the contact angle of the top coat layer 500 to prevent contamination, increases the hardness, gives scratch resistance, and increases the gloss. Also, water repellency and oil repellency are imparted to the top coating layer 500 by the fluorine compound.

Some examples of fluorine-based compounds include acrylates, methacrylates, vinyls and the like containing perfluoro groups. Such a fluorine-based compound is preferably contained in an amount of 0.5 to 15 parts by weight based on 100 parts by weight of the entire coating composition. If the content of the fluorine compound is less than 0.5 parts by weight, the resistance to stain resistance and scratch resistance of the answer coating layer 500 is insufficient, and if it exceeds 15 parts by weight, the transparency of the top coat layer 500 is lowered.

The type of the photoinitiator is not particularly limited as long as it is a commonly used UV curable initiator. Some examples of photoinitiators are 1-hydroxycyclohexyl phenyl ketone, benzoin, benzoin methyl ether, benzoin ethyl ether, benzoin isopropyl ether, benzoin butyl ether, or mixtures thereof.

The photoinitiator is preferably included in an amount of 0.1 to 10 parts by weight based on 100 parts by weight of the total amount of the finish coating agent. When the content is less than 0.1 part by weight, curing may not occur. When the amount is more than 10 parts by weight, surface curing / through curing becomes worse, and the physical properties of the surface of the top coating layer 500 are lowered .

In addition, the inorganic nanoparticles form fine irregularities on the surface of the top coating layer 500 to impart high water repellency to the top coating layer 500. As the inorganic nanoparticles, silica, alumina, titania or the like having an average particle diameter of 5 to 20 nm is preferably used, and a surface treated with a small amount of water is preferably used.

Mineral treatment of inorganic nanoparticles is achieved by coating the surface of the inorganic nanoparticles with the following surface treatment solution. The surface treatment solution is prepared by dissolving alkoxysilane in an organic solvent, adding an acidic or basic catalyst and water thereto, hydrolyzing and polycondensing the alkoxysilane, and then diluting the alkoxysilane with an organic solvent. When the inorganic nanoparticles are coated on the thus prepared surface treatment liquid and dried, the surfaces of the inorganic nanoparticles are treated with a small amount of water.

Such inorganic nanoparticles are included in an amount of 5 to 15 parts by weight based on 100 parts by weight of the total of the finish coating agent. If the amount of the inorganic nanoparticles is less than 5 parts by weight, the effect of improving the water repellency by the inorganic nanoparticles can not be expected. If the inorganic nanoparticles are contained in an amount exceeding 15 parts by weight, the other properties of the top coating layer 500 are lowered.

Examples of the solvent include acetone, ethanol, N-methyl pyrrolidone, N-vinyl pyrrolidone, N-acetyl pyrrolidone, Dimethyl sulfoxide, xylene, ethyl acetate, butyl acetate, methanol, ethylene glycol and the like are used.

The amount of such a solvent to be used is adjusted so as to have a viscosity suitable for coating the finish coating agent, preferably 5 to 30 parts by weight based on 100 parts by weight of the total of the finish coating agent.

Such a finishing coating agent is coated by a conventional coating method, preferably by a gravure printing method, and is cured by irradiating ultraviolet rays.

The top coating layer 500 formed by the finishing coating agent having such a composition not only has excellent scratch resistance and gloss resistance, but also has an excellent stain resistance and water repellency.

The present invention having the above-described constitution is produced by the following method.

First, as described above, the woody foam substrate 100 is molded by extrusion foaming at a high temperature and a high pressure, a molding mixture containing wood fibers or wood fibers, a resin and a foaming agent.

Then, the stabilized coating agent is coated on the upper surface of the molded woody foam substrate 100 and dried to form the dimensionally stabilized layer 200. Next, the decor layer and the waterproof film are sequentially laminated on the dimension stabilizing layer 200 to form the print pattern layer 300 and the waterproof layer 400. The decor sheet and the waterproof film are laminated by a separate adhesive.

Finally, the waterproof layer 400 is coated with a finish coating agent and cured with ultraviolet rays to form a top coat layer 500.

According to the present invention having the above-described structure, the wood-based foamed base material constituting the base is foam-molded to be lightweight, has heat insulation and sound-absorbing properties, and is prevented from being deformed in size and shape by moisture or heat by the dimension- And is excellent in water resistance and water repellency by the waterproof layer 400 and the top coating layer 500.

Example 1

The floor board was manufactured as described above and the properties of the floor board were tested.

The woody foam substrate was molded into a size of 60 mm x 360 mm x 6 mm with a molding mixture containing 55 parts by weight of wood fibers, 55 parts by weight of a polyolefin resin and 2.0 parts by weight of a foaming agent.

The dimensionally stabilizing layer was formed by coating a stabilizing coating agent containing 80 parts by weight of a polyolefin resin, 15 parts by weight of a stabilizer, 15 parts by weight of a solvent, 20 parts by weight of a filler and 15 parts by weight of a flame retardant, based on 100 parts by weight of the whole.

 80 parts by weight of an emulsion polymer of acrylic acid, dimethylaminoethyl acrylate and acrylonitrile, 40 parts by weight of an aqueous dispersion of an epoxy resin, 10 parts by weight of an acrylonitrile-butadiene copolymer, 10 parts by weight of tetraalkoxysilane 25 By weight based on the total weight of the film.

The top coat layer was formed by coating 80 parts by weight of a UV-curable functional group-containing resin, 15 parts by weight of a fluorine-based compound, 10 parts by weight of an inorganic nano-particle, 5 parts by weight of a photoinitiator and 15 parts by weight of a solvent.

(1) Water contact angle test

 Water was dropped on the upper surface of the manufactured floor board and the water contact angle was measured using a contact angle measuring instrument. The result was a contact angle of 118 °.

Generally, the contact angle of water to water is evaluated as having a water-repellency when the contact angle is 90 to 120 °, and when the contact angle to water is 120 ° or more, it is evaluated as having super-water repellency. .

Fig. 3 is a photograph showing a state in which water is dropped on the upper surface of the floor board material, and it can be seen that water does not spread on the floor board but is gathered in a droplet state. It can also be seen that the floorboard according to the present invention has excellent water repellency.

(2) Scratch resistance test

The scratch resistance was tested with pencil hardness. The pencil hardness was measured according to JIS K5600-5-4KS. (Pencil hardness is tested for hardness in the following order, and the order is from 9B to 9H.) The hardness becomes weaker toward 9B and stronger toward 9H.

As a result of the experiment, 5 repetition tests were performed at 8H. No traces were observed at 3 times, and no trace was observed at 2 times. If the pencil hardness is 8H or more, it can be judged that scratch resistance is remarkably excellent as scratch resistance on the level that scratches do not occur on the coated film even if scratched with a coin.

(3) Stain resistance test

At the room temperature of 20 占 폚, the top surface of the prepared floor board was exposed with oily ink and allowed to stand for one hour, and then rubbed five times with a commercially available tissue paper. As a result of observation with naked eyes, no oily ink was observed.
