one or more polyether polyols,
A one-component urethane resin consisting of a urethane prepolymer containing terminal isocyanate groups obtained by reacting with a polyisocyanate such as TDI,
Alternatively, a urethane resin obtained by a reaction between the urethane prepolymer and a crosslinking agent is preferable.
上記架橋剤はエチレンキサイド（EO）、プロピ
レンオキサイド（PO）からなるEO−PO−EOタ
イプ（EO40％程度 OHV30−40）の共重合体が
適当である。 The crosslinking agent is suitably an EO-PO-EO type copolymer (EO40% OHV30-40) consisting of ethylene oxide (EO) and propylene oxide (PO).
さらに本考案の止水構造ではパイプ３の外周に
水膨潤性樹脂製リング状パツキン４を装着するの
が特に好ましい。 Furthermore, in the water stop structure of the present invention, it is particularly preferable to attach a ring-shaped packing 4 made of water-swellable resin to the outer periphery of the pipe 3.
