COMPOSITION FOR MANUFACTURING FLAME-RETARDANT HARD URETHANE FOAM, AND METHOD FOR MANUFACTURING FLAME-RETARDANT HARD URETHANE FOAM USING SAID COMPOSITION

摘要

Provided is a composition for manufacturing a flame-retardant hard urethane foam that uses a small amount of flame retardant, and a method for manufacturing a flame-retardant hard urethane foam with an oxygen index of 32% or higher in which the composition is used. The present invention contains a polyol (A), a catalyst (B), a foaming agent (C), a foam stabilizer (D), and a flame retardant (E). The catalyst (B) is an aqueous solution containing more than 50% by weight of a quaternary ammonium salt expressed by general formula (1); and the flame retardant (E) content is 120 parts by weight or less per 100 parts by weight of the polyol (A) (R¹ to R⁴ represent a C_1-12 aliphatic hydrocarbon group or a C_6-14 aromatic hydrocarbon group; X^b- represents an acidic group; a represents 1 to 3; and b represents 1 to 3).
