Abstract

An object of the present invention is to provide a catalyst for producing a rigid polyurethane foam and an isocyanurate-modified rigid polyurethane foam excellent in storage stability in the case that water is contained as a blowing agent, and a raw material-blended composition using the same. In the present invention, a catalyst composition comprising the following amine compounds of (A) and (B) and / or (C) is used and further, a raw material-blended composition further containing a polyol component and water is used. (A) A quaternary ammonium salt represented by the following general formula (1): wherein each of R1 to R3 represents a hydrocarbon group having 1 to 12 carbon atoms, R4 represents an alkyl group or an aromatic hydrocarbon group having 1 to 18 carbon atoms, and X represents an organic acid group having an acid dissociation constant (pKa) of 4.8 or less; (B) A hydrophobic amine compound; (C) A heterocyclic tertiary amine compound.

Description

TECHNICAL FIELD

[0001] The present invention relates to a catalyst composition used in producing a rigid polyurethane foam and / or an isocyanurate-modified rigid polyurethane foam, a raw material-blended composition containing the catalyst composition, a polyol component and water, and a process for producing a rigid polyurethane foam and / or an isocyanurate-modified rigid polyurethane foam by reacting the raw material-blended composition with a polyisocyanate. BACKGROUND ART

[0002] Since rigid polyurethane foams and isocyanurate-modified rigid polyurethane foams are excellent in heat insulation and self-adhesiveness, they are widely used as heat-insulating materials for electric refrigerator, building materials, and the like. The rigid polyurethane foams and isocyanurate-modified rigid polyurethane foams to be used for these applications are generally obtained by a method of mixing, with a polyisocyanate, a raw material-blended composition having mixed therewith a polyol component, a...
