METHOD FOR PRODUCING POLYURETHANE FOAM

摘要

PROBLEM TO BE SOLVED: To provide a method for producing polyurethane foam in which the amount of VOC (volatile organic compounds) generated from polyurethane foam on the basis of an amine-based catalyst is reduced even in a high-temperature state and fogging hardly occurs and which has excellent heat resistance, excellent hardness properties and small residual compressive strain. SOLUTION: The method for producing a polyurethane foam comprises reacting a polyol component with an isocyanate component in the presence of a catalyst containing a compound represented by formula (I): (CH3)2N(CH2)pOH (1) (p is an integer of 4-9) and a compound represented by formula (II) (R1is a 2 or 3C straight-chain or branched-chain aminoalkyl group or hydroxyalkyl group; R2is a hydrogen atom or a 1-4C straight-chain or branched-chain alkyl group) and a blowing agent. The polyurethane foam is obtained by the production method. COPYRIGHT: (C)2005,JPO&NCIPI
