Description of the Related Art A conventional vibration damping plywood has a sound insulation layer provided on the back surface of a surface material with a vibration insulation layer interposed therebetween to achieve vibration and sound insulation on a floor surface (Japanese Patent Laid-Open No. 60-2269).
34) A plate-like restraining member made of a plate-like material such as plywood is used as a core material on the back surface of the floor material main body, and a vibration-damping material made of a sheet-like material such as rubber is formed on one surface and foam-synthesized on the other surface.

Using the material mixed with 80 degree granules, apply and fill the above adhesive not only on the surface of the plywood veneer stretched by 10 to 50% with a tender, but also in the crack part, and adhere it. Things.

る。[0007] The adhesive includes a solvent type, a latex type and an emulsion type. In order to increase the solid content of these adhesives, a filler used in the conventional adhesive for plywood is added within a range that does not hinder the filling of the adhesive into the cracks generated in the veneer. be able to. Still preferably, the particle size is 0.1 to 0.5 mm,
By mixing an appropriate amount of granular material having a hardness of 5 to 80 degrees into the adhesive, the veneer veneer does not directly contact but is bonded through the granular material, so that a high vibration damping effect can be obtained.

る。Examples of the granular material include various rubbers, EVA, polyethylene, and other synthetic resins having a hardness within the above range, wood sawdust, cork, and other crushed products of foamed synthetic resins. In particular, crushed waste tires are preferable because they are inexpensive and absorb vibrations well. If the hardness of the adhesive after drying is less than 5 degrees, the adhesive strength is small and a plywood that can withstand use cannot be obtained, and if it exceeds 80 degrees, the vibration damping effect becomes poor.

If less than m, the effect of preventing direct contact of the plywood veneer cannot be obtained due to the interposition of the granular material, and if it exceeds 0.5 mm, it becomes difficult to uniformly adhere the adhesive to the plywood veneer. Not preferred. If the hardness of the granular material is out of the range of 5 to 80 degrees, the vibration damping effect becomes poor.

得られない。Generally, a tender is a machine for making a crack in a direction parallel to a fiber direction of a veneer, and is used to eliminate a curl of a veneer and to make a veneer of a flat plate. According to the present invention, the crack caused by the tender is further increased and the crack is filled with a soft adhesive, so that sound propagation is prevented and a high damping effect is obtained. If the tender elongation is less than 10%, no effect is observed. On the other hand, if it is longer than 50%, the veneer is too elongated and it is difficult to apply the adhesive, and the adhesive strength cannot be obtained.

安価に生産することができる。The plywood of the present invention has a hardness of 5 after drying.
Since the plywood veneer is bonded by using an adhesive of 〜80 degrees or a mixture of the adhesive and a granular material having a hardness of 5 to 80 degrees, it can be produced at low cost. In addition, since the soft adhesive is filled into the cracks of the veneer veneer by the tender, the propagation of sound can be greatly reduced, and the manufacturing process is not different from the conventional veneer.
It can be produced at low cost.

ている。As is clear from the above Examples and Comparative Examples, the energy generated in the Comparative Example using a urea resin having high hardness even after drying was as large as 96 dB or 97 dB, whereas the energy generated in the Examples was as large as 96 dB or 97 dB. The largest value of-is reduced to 85 dB, and the smallest value is reduced to 81 dB.

場合は音の強さは半分になったことを示すものである。Further, a decrease of 3 dB has been observed by applying a tender. The calculation of the generated energy is performed by the following equation. L = 10 log (P / P.) Accordingly, when the sound is absorbed by the damping plywood and the sound is reduced by 3 dB, it indicates that the sound intensity has been halved.

ものである。As described above, the vibration damping plywood of the present invention greatly reduces the rate of noise coming out of the vibration damping plywood because the object absorbs the impact sound generated when the object hits the vibration damping plywood. In addition, even when a heavy object is placed on the damping plywood, no dents are generated partially and the stability is good.
