Board manufacturing method for reducing noise between floors and board using same

The present invention relates to manufacturing a board for reducing inter-floor noise， and more particularly， a buffer capable of absorbing and reducing shock noise or vibration that causes inter-floor noise in commercial facilities such as shopping centers， apartments， and apartment houses such as villas. A method of manufacturing a board for interlayer noise reduction that can increase product satisfaction by effectively absorbing and reducing the impact sound or vibration that causes interlayer noise through a simple structural change with additional cork boards And as to a board using the same， the specific means of the present invention， "The first plywood 30 formed by adhering 3 to 7 veneers (V) cut to a predetermined size with an adhesive 10 and the bottom surface of the first plywood 30 by applying an adhesive 10 to After bonding the cork board 40 and 3 to 7 veneers cut to a predetermined size with an adhesive 10， the second plywood 50 bonded to the adhesive 10 applied to the bottom of the cork board 40 Sequential bonding and cold pressure 9 ± 1 kg/cm 2 Seasoning time 30~50 minutes After cold press， 9~13kg/cm for 20~60 seconds with a hot press with a hot plate temperature of 100~1502Including a state of hot pressure at a pressure of， and the veneer (V) is a steam dryer with a steam pressure of 13 kg/cm2， Including drying at a temperature of 170°C， A method of manufacturing a board for reducing interlayer noise comprising alternately laminating and bonding the first plywood 30， the cork board 40， and the second plywood 40， and predetermined A first plywood 30 formed by adhering 3 to 7 veneers (V) cut to the size of with an adhesive 10 and a cork board adhered by applying an adhesive 10 to the bottom of the first plywood 30 After bonding 40 and 3 to 7 veneers cut to a predetermined size with an adhesive 10， the second plywood 50 adhered to the adhesive 10 applied to the bottom of the cork board 40 is sequentially Glued and cold pressure 9 ± 1 kg/cm2 Seasoning time 30~50 minutes After cold press， 9~13kg/cm for 20~60 seconds with a hot press with a hot plate temperature of 100~1502Including a state of hot pressure at a pressure of， and the veneer (V) is a steam dryer with a steam pressure of 13 kg/cm2， Including drying at a temperature of 170° C.， the first plywood 30， the cork board 40， and the second plywood 40 are alternately laminated and bonded to each other. As a feature， the present invention made of the above configuration can be used as a wall material as well as a flooring material， so that the impact sound and friction sound of the wall material， and the impact sound and friction sound of the floor material， etc. can be reduced to 20 to 30 decibels (dB). The air gap provided in the cork board distributes the load that cushions and elasticity is transmitted to the body when walking， reduces fatigue when walking， and has excellent insulation/heat insulation， saving heating costs， and harmful components (radon， chromium) from molten (concrete). Etc.)， and it has strong durability against moisture， which reduces deformation， and enables maintenance of temperature and humidity to prevent warpage， and also promotes economic efficiency by saving raw materials and abrasion resistance， impact resistance， and fading resistance. Resistance， cold resistance， durability， It is excellent in heat resistance， and by applying heat during ondol， it can exhibit the effect of solving the problem of cracking due to contraction and expansion.
