する場合と、合板等の基板に塗布、硬化せしめたものを
床材として使用する場合とがあるが、通常は機械的強度
等を考慮して後者の場合が広く採用されている。[Prior art and problems to be solved by the invention] Compositions consisting of polyether polyol compounds, polyisocyanate compounds, and asphalt have been known, and it has also been known to use these compositions as flooring materials. (Japanese Patent Publication No. 53-44343). Such a composition may be used as a flooring material in its cured form, or it may be applied and cured on a substrate such as plywood, but usually it has mechanical strength etc. Considering this, the latter case is widely adopted.
しかしながら、このような従来の床材は、防音性には比
較的すぐれているものの、湿気に対する耐性に劣り、床
下からの湿気により劣化しやすいという大きな欠点があ
った。However, although such conventional flooring materials have relatively good soundproofing properties, they have a major drawback in that they are inferior in resistance to moisture and are easily deteriorated by moisture coming from under the floor.
そこで、本発明者らは上記従来の床材の欠点を解消し、
防音性とともに湿気に対する耐性のすぐれた新たな床材
を開発すべく鋭意研究を重ねた。Therefore, the present inventors solved the drawbacks of the above conventional flooring materials,
We conducted extensive research to develop a new flooring material that is both soundproof and moisture resistant.
