余地がある。[Problems to be Solved by the Invention] However, since the damping sheet and the particle board are different core materials for the vibration-damping floor base material, they have been manufactured separately and then integrated. Therefore, there is room for improvement in terms of manufacturability.
【0005】本発明は、以上の点に鑑み、心材を、制振

The required amount of each chip was kneaded and heated and pressurized to form an integrated product.

60 to 220 parts by weight as 0 mm, 60 to 90 parts by weight of butyl rubber as the heat-fusible rubber, 10 to 40 parts by weight of the polyethylene, and 240 to 6 parts of the wood chips.
The amount is preferably 40 parts by weight. At this time, it is preferable to mix equal amounts of vulcanized granular rubber with different average particle sizes, and it is also possible to use recycled butyl rubber in part for the butyl rubber. It is preferable to use 100 parts by weight.
