Zusammenfassung:A crosslinking additive composition for a polyurethane foam, and a method for preparing a polyurethane foam by using the composition as a crosslinking additive are provided to improve the deterioration resistance of a polyurethane foam in case of wet aging by enhancing the stability of a polyurethane foam. A crosslinking additive composition for a polyurethane foam comprises a nonvolatile tertiary amine urethane catalyst; and at least one polyamine compound represented by (R)N(R')-[(CH2)m-NR']N-R', wherein R is a C1-C18 alkyl group, a substituted alkyl group, a substituted alkenyl group, an aryl group, a substituted aryl group or an alkylaryl group; R' is independently H or R; m is 2 or 3; and n is an integer of 1-10. Also the crosslinking additive composition comprises a nonvolatile tertiary amine urethane catalyst; at least one polyol; and at least one polyamine compound represented by (R)N(R')-[(CH2)m-NR']N-R'.
