FIELD: chemistry.
SUBSTANCE: catalyst is a product of reacting compounds (a) and (b). Compound (a) is a mixture of (i) a compound which contains at least one opxy group with (ii) a compound which contains an alcohol, amino-, thio- or carboxyl group and an aldehyde or ketone group. Compound (b) contains at least one primary amino group and at least one tertiary amino group.
EFFECT: use of the proposed non-volatile catalyst to produce polyurethane foam reduces the need for traditional volatile amine catalysts, speeds up bonding of organic polyisocyanates to polyhydroxyl or polyamino compounds and the reaction between isocyanate and foaming substance, and reduces the time for holding polyurethane foam material in the die mould and improves characteristics of the foam.
