Abstract
PURPOSE: To obtain the titled foam useful as an insulating material having low thermal conductivity, by combining an amine type polyol as a main ingredient with an aromatic polyester polyol as an auxiliary.
CONSTITUTION: A polyol obtained by combining at least two components of (A) 60W98wt% amine type polyol (e.g., a polyol having a hydroxyl number of 445 prepared by adding ethylene oxide and propylene oxide to metatolylenediamine, etc.) having a hydroxyl number of 350W600 obtained by adding an alkylene oxide to an amine type compound and (B) 20W40wt% aromatic polyester polyol (e.g., a polyol having a hydroxyl number of 400 prepared by reacting phthalic anhydride with ethylene glycol) having a hydroxyl number of 200W600 is reacted with a polyisocyanate (e.g., tolylene diisocyante, etc.) to give the desired compound. 2W40wt% based on (the component A + the component B) of a low- molecular polyol having a molecular weight of ≤350 and a hydroxyl number of 2W4 may be used as the polyol component.
