Provided is a catalyst composition which improves the storage stability of a liquid
polyol blend for the production of a
polyurethane foam, said blend containing a hydrohaloolefin as a
foaming agent,and which starts a quick foaming reaction with a small addition amount. Also provided is a method for producing a
polyurethane foam with use of a liquid
polyol blend which contains this catalyst composition. The present invention uses a catalyst composition which contains: one or more alcohols selected from the group consisting of alcohols represented by general formula (1) (hereinafter referred to as the alcohols represented by general formula (1)) and alcohols represented by general formula (2) (hereinafter referred to as the alcohols represented by general formula (2)); and one or more
tertiary amine compounds selected from the group consisting of hexamethyl triethylene
tetramine, N, N, N'-trimethyl aminoethyl
ethanolamine, N, N-dimethylamino ethoxy
ethanol, N, N-dimethyl-N', N'-di(2- hydroxypropyl)propylene
diamine, N, N, N'-trimethyl-N'-(2- hydroxyethyl)bis(2-aminoethyl)
ether and N, N-dimethylamino ethyl-N'-methylamino ethyl-N"-methylamino isopropanol. (In general formula (1), R1represents an
unsaturated hydrocarbon group containing at least one
double bond and having 5-20 carbon atoms, a linear
alkyl group having 6, 8, 10 or 12 carbon atoms or a branched
alkyl group having12-24 carbon atoms.) (In general formula (2), m represents a number of 1-4.)
