Abstract

PURPOSE: To produce a rigid polyurethane foam having excellent flame retardancy and controlled deflagration, by adding to a polyurethane-forming material a phosphorus and halogen-containing flame retardant and a specified foam stabilizer, and reacting the resulting mixture.
CONSTITUTION: To a polyurethane-forming material comprising (A) a polyhydroxyl compound, (B) an organic polyisocyanate, NCO/OH eq. ratio 0.8W1.3, (C) up to 65wt%, based on component A, aliphatic polyamine/alkylene oxide adduct, (D) a urethane production catalyst such as triethylamine and (E) a blowing agent such as pentane are added (F) a phosphorus and halogen-containing flame retardant such as tris(2-chloroethyl) phosphate, in an amount to provide a phosphorus content of 0.2W5.0wt% and a halogen content of 0.6W10wt%, based on the total (X) of components A and B and (G) a foam stabilizer having a chain represented by the formula, wherein R1 and R2 are each an alkyl and (n) is a positive integer, in an amount to provide an Si content of 0.03W0.3wt% based on X.
