Abstract

PURPOSE: To obtain the titled soft to semihard open-cell sealing material with excellent waterproofness, by the reaction of a polyol with a polyisocyanate using a prim. or sec. amino acid-contg. organosilicon compd. as a foam stabilizer.
CONSTITUTION: In the reaction of a polyol (A) with a polyisocyanate (B) in the presence of a foam stabilizer (C) and a foaming agent (D), a soft to semihard open-cell polyurethane foam sealing material of permeability ≤ about 100cc/ cm2sec, 10mm in thickness, is obtd. by use of an organosilicon compd. having a prim. and/or sec. amino group as the agent C. It is pref. to use as the material A 20wt% or more polydiene polyol, dimer acid polyol and castor oil-derived polyol separately or in a mixture and to mix the material with a plasticizer or an animal or vegitable oil such as a hydrocarbon or dicarboxylate ester of atmospheric b.p. ≥200°C and m.p. or softening pt. ≤150°C. The sealing material can prevent water from leaking, while keeping gas permeability.
