WATER-HOLDING CAPACITY IMPARTING AGENT, AND WATER HOLDING METHOD FOR POROUS MATERIAL
To solve the problem in which: when a composition that contains a polymer having a crosslinkable functional portion and a crosslinker is applied as a water-holding agent to a porous material such as porous pavement, it is difficult to adjust the time for its gelation, and if its density is adjusted for a required absorbency, the gelation takes too much time, so that the water-holding capacity cannot be sufficiently exhibited.SOLUTION: A water-holding capacity imparting agent contains: a compound comprising 5 mol or more of alkylene oxide added to 1 mol of a polyhydric alcohol having a valence of three or more, in which a terminal structure of polyalkylene oxide has hydrogen or a hydrocarbon group; and cyclodextrin.SELECTED DRAWING: None
【課題】 多孔質舗装体等の多孔質材料に、架橋性官能部分を有するポリマーと架橋剤を含む組成物を保水剤とした場合、ゲル化までの時間を調整することが困難であり、必要な吸水性で濃度を調整するとゲル化に時間がかかりすぎ、結果として保水性能が十分に発揮されないという問題がある。【解決手段】 ３価以上の多価アルコール１モルにアルキレンオキシドが５モル以上付加された構造する化合物であって、ポリアルキレンオキシドの末端構造が水素または炭化水素基を有する化合物とシクロデキストリンを含有する保水性付与剤。【選択図】なし
