The present disclosure provides a method for reducing the aldehyde content in an amine catalyst by treating the amine catalyst with a treating agent selected from a cyclic urea substituted with at least one isocyanate reactive group, a free radical scavenger and a mixture thereof. The treated amine catalyst may then be used in the production of polyurethane materials which exhibit reduced aldehyde emissions.
本公开提供了一种降低胺催化剂中醛含量的方法,即用一种处理剂处理胺催化剂,该处理剂选自至少一个
异氰酸酯活性基团取代的环状
脲、自由基清除剂及其混合物。处理后的胺催化剂可用于生产醛排放量减少的聚
氨酯材料。
