In the preparation of a high resiliency polyurethane foam by reacting a polyisocyanate with a polyurea dispersion-containing polyol based masterbatch composition also containing a tertiary amine catalyst for the polyurethane reaction, the improvement for eliminating cure draft of such stored polyol compositions which comprises employing a catalyst composition consisting essentially of
5 to 15 wt% triethylenediamine,
20 to 35 wt% 4-(2-dimethylaminoethyl) morpholine,
20 to 35 wt% N,N,Nʹ,Nʹ-tetramethyl-1,2-diamino-2-methylpropane,
10 to 25 wt% bis(dimethylaminoethyl)ether, and
5 to 40 wt% of an N-hydroxyalkyl quaternary ammonium acid salt.
在通过使多异氰酸酯与含有聚脲分散体的多元醇基母料组合物反应制备高回弹性聚氨酯泡沫塑料的过程中,该母料组合物还含有用于聚氨酯反应的叔胺催化剂,用于消除此类储存多元醇组合物的固化气流的改进包括采用一种催化剂组合物,该催化剂组合物主要由5至15 wt%的三乙二胺、20至35 wt%的4-(2-二甲基氨基乙基)吗啉、20至35 wt%的N,N,Nʹ,Nʹ-四甲基-1,2-二氨基-2-甲基丙烷、10至25 wt%的双(二甲基氨基乙基)醚和5至40 wt%的N-羟基烷基季铵酸盐组成。
