Abstract

PURPOSE: To obtain a rigid urethane foam which is excellent in water resistance, moisture resistance, and heat insulation and is useful as building material, by using a polyol to which a specific amount of styrene oxide is added.
CONSTITUTION: A rigid polyurethane foam is manufactured from a polyol (A), e.g., a polyol to which 1W10mol of an alkylene oxide containing 50mol% or more of styrene oxide per one hydroxyl group of a polyhydroxyl compound is added, or a polyol containing 50wt% or more, based on total polyol, of a polyol obtained by adding 1W10mol of styrene oxide per one hydroxyl group of a polyhydroxyl compound, a polyisocyanate (B), a foaming agent (C), a catalyst (D), and a surfactant (E).
