Abstract

A vibrationproof underfloor heating floor and a manufacturing method thereof are provided to absorb impact sound effectively by utilizing a cork laminated board with sound absorbance, vibrationproof, and high elasticity. A vibrationproof underfloor heating floor comprises a cork laminated board layer(20), an adhesive layer(A), a plywood layer(10), an adhesive layer, a cork laminated board layer, an adhesive layer, a surface layer(30), and a UV coating layer(40), which are laminated sequentially from the bottom. A cork laminated board of the cork laminated board layer is made by burning 0.1 to 5 mm cork particles. The thickness of the cork laminated board ranges from 0.8mm to 6mm. The density of the cork laminated board ranges from 380kg/m3 to 550kg/m3.

The present invention relates to a dustproof ondol floor and a method of manufacturing the same, and more particularly, to a method for manufacturing ondol floor that can be used comfortably and quietly in indoor use by utilizing the advantages of a sound absorbing, dustproof, and high elasticity cork plate. will be.

Cork is a porous cell formed in the epidermis, cortex, primary part and secondary part of the bark of oyster oak bark, and has about 42 million honeycomb-shaped porous cells per cubic centimeter. Almost none, most are natural substances containing fatty acids and small amounts of lignin, ash, resins and carbohydrates.

Cork cells made of porous cells are impermeable, elastic and flexible compartments, and the aggregates do not pass through the liquid so that they do not penetrate even 10% diluted boiling hydrochloric acid.

Chemically inert, it is not damaged by weak acid weak bases or most organic solvents.

Formed of porous honeycomb cells, wrapped in a resin membrane, packed in half of the volume and filled with air, it is very light and has a characteristic of returning to its original state even after strong pressure. / Gaskets for automobiles / High speed railroads have been used for industrial applications such as dustproof pads.

Conventional ondol flooring is a product made by bonding a surface material layer (veneer or solid wood veneer, HPM, LPM, decorative board, etc.) and a base material layer (plywood or mixed wood veneer), and the material itself is hard wood, but it improves durability and wear resistance in the production process It is hardened by special treatment such as surface coating for the floor, so that in the apartment sharing the ceiling and floor, when the small impact caused by human walking, falling objects, children jumping or running, or moving furniture is applied to the floor In addition, the floor slab was bent and vibrated in the air, causing large residential noises to cause disputes between neighbors. The floor was so hard that the elderly, women, and children were not comfortable walking.

It is an object of the present invention to provide a method for providing a dustproof ondol floor having easy walking and significantly reducing the residential noise of a multi-family house in consideration of the above deficiency, and having antibacterial, anti-fungal, deodorizing and far-infrared radiation ability.

Features of the present invention for achieving the object of the present invention as described above are as follows. The method of manufacturing the dust-proof ondol floor is formed by corrugated sheet (coke particles Ø 0.1 to 5 mm thermoplastic molded on both sides or one side of the plywood material (plywood, HDF, magnesium board, various plastic hardening plates) to be used as the base material of the ondol floor. First, the thickness of 0.8mm ~ 6mm Density 380 ~ 550kg / ㎥ is laminated to the adhesive material (optional among urea, melanin, panol, vinyl acetate, acrylic, urethane, epoxy, polyester resin) and surface material (0.5mm of natural veneer) , 2mm ~ 4mm of solid wood veneer, LPM, HPM, makeup plate, etc.) to secondary lamination on one side of corrugated board or on one side of plywood, and UV coating and UV curing of surface material layer for durability and wear resistance The cutting process is carried out as the configuration.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The adhesive is applied to both sides or one side of the laminate using a spreader, and when the cork aggregate is laminated with a thermosetting adhesive, it is laminated by thermal compression at a temperature of 10 ± 5KGf / ㎠ at a temperature of 60 ° to 80 ° C. for 3 to 10 minutes. When laminating with room temperature curing adhesive, press the same pressure for 3 to 6 hours to laminate first, and then apply adhesive on one side of cork aggregate plate or one side of plywood using spreader and deposit the desired surface material layer as above. After pressing by hot or cold pressure having a proper temperature and pressure, the secondary laminates are aged at room temperature for 8 hours or more.

For abrasion resistance, durability, veneer, wood veneer, and surface coating layer, after removing foreign substances with primary surface sanding, urethane acrylate paint is applied on top of it by using roll coater, curing / medium, curing, sanding / coating, curing, etc. The coating is cured by passing through an ultraviolet lamp.

Surface materials, such as LPM, HPM, makeup plate, and the like after UV primer coating after UV brushing and UV-curing.

After aging at low temperature for more than 12 hours, it is cut and processed to a certain form. Finally, the top layer is applied using a direct roll coater, and then cured by passing through an ultraviolet lamp.

1, 2, and 3 are shown in large divisions.

The dustproof ondol floor manufactured according to the present invention possesses a beautiful and natural texture of natural veneer or wood veneer as a surface material by applying at least one layer of cork aggregate plates having a function of high elasticity, dustproof, sound absorption, etc. in the construction of ondol floor. While walking, there is a cushioning feeling, so that the ankle, knee, waist, etc. are comfortable, and the fatigue of housework is less felt for a long time. Anti-vibration, deodorant, far-infrared radiation dustproof ondol flooring.

Claims (2)

In the method of manufacturing the anti-vibration ondol floor, the cork aggregate board is first laminated on both sides or one side of the laminate to be used as the base material of the ondol floor, and the surface material is secondly firmly laminated on one surface of the cork aggregate plate or one surface of the laminate with an adhesive Method of manufacturing ondol floor which cuts UV coating of layer to urethane acrylate paint by repeated polishing coating curing through roll coat and UV lamp In the construction of the dust-proof ondol floor, the cork collecting plate layer, the adhesive layer, the laminate layer, the adhesive layer, the cork collecting plate layer, the adhesive layer, the surface material layer, and the UV coating layer are included from below.
