PRODUCTION OF POLYURETHANE FOAM THERMAL INSULATION MATERIAL

Title:

PRODUCTION OF POLYURETHANE FOAM THERMAL INSULATION MATERIAL

Document Type and Number:

Japanese Patent JP3242090

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a method for producing the subject thermal insulation material, favorable in foam fluidity during molding process, excellent in demoldability after the molding process, and capable of giving the polyurethane foam with high compressive strength and thermal conductivity retention.
SOLUTION: This method for producing the objective polyurethane foam as thermal insulation material comprises reaction between a polyol component and an isocyanate component in the presence of (A) a catalyst comprising a quaternary ammonium salt and at least one compound selected from N,N,N',N'- tetramethyl-1,6-hexanediamine, N,N-dimethylcyclohexylamine and N-(2- dimethylaminoethyl)-N'-methylpiperazine, (B) a foaming agent composed of water and cyclopentane and (C) a foam stabilizer.
