To provide a catalyst composition which is a catalyst composition not impairing the physical properties of a polyurethane resin and the storage stability of the starting material blend liquid and which is capable of producing a polyurethane resin excellent in curability and also excellent in moldability by suppressing the initial reactivity, with good productivity.
A catalyst composition for production of a polyurethane resin, which comprises (A) triethylenediamine, and (B) a polyisocyanurating catalyst and/or (C) a highly temperature sensitive catalyst, wherein the polyisocyanurating catalyst (B) is one or more compounds selected from the group consisting of an alkali metal salt of a carboxylic acid, a quaternary ammonium salt compound of the following formula (1):
wherein each of R1 to R3 is a C1-12 linear or branched, saturated or unsaturated hydrocarbon group, provided that any two among R1 to R3 may form a hetero ring via an oxygen atom or a nitrogen atom, R4 is a C1-18 alkyl group or an aromatic hydrocarbon group, and X is an organic acid group having an acid dissociation constant (pKa) of at most 4.8, N,N,N'-trimethylaminoethylethanolamine and 2,4,6-tris(dimethylaminomethyl)phenol; the highly temperature sensitive catalyst (C) is one or more compounds selected from the group consisting of a triazole salt of 1,8-diazabicyclo[5.4.0]undecene-7, a benzotriazole salt of 1,8-diazabicyclo[5.4.0]undecene-7, a triazole salt of 1,5-diazabicyclo[4.3.0]nonene-5, a benzotriazole salt of 1,5-diazabicyclo[4.3.0]nonene-5, a triazole salt of 1,8-diazabicyclo[5.3.0]decene-7 and a benzotriazole salt of 1,8-diazabicyclo[5.3.0]decene-7; and the blend ratio of the polyisocyanurating catalyst (B) and/or the highly temperature sensitive catalyst (C) to the triethylenediamine (A) is from 2 wt% to 60 wt%.
