Abstract

PURPOSE: A urethane foam composition having excellent heat-insulating property, obtained by employing, as a polyol component, a polyether prepared by addition- polymerizing xylenediamine (derivative) with an alkylene oxide.
CONSTITUTION: A foam is produced by addition-polymerizing xylenediamine (derivative) with an alkylene oxide such as propylene oxide thereby to yield a polyether, OH value 350W600mg KOH/g, and foaming the polyether, after mixing therewith a polyisocyanate, a blowing agent, a catalyst and a foam stabilizer. As the polyol component, a mixture of at least 60pts.wt. of said polyether and at most 40pts.wt. of a general-purpose polyether such as a sucrose type or a sorbitol tape may also be used.
EFFECT: A rigid polyurethane having a thermal conductivity of 0.015W0.016Kcal/m h°C can be obtained.
