摘　　要：研究了不同胺类催化剂对聚氨酯软泡发泡前后醛含量的影响,以及长期储存时催化剂本身醛含量的变化和泡沫气味问题。结果表明,由于催化剂RZETA特殊的环状结构以及伯羟基作为反应基团,减少了胺类与醛类化合物的散发,有效地解决催化剂所引起的泡沫异味问题。The content of aldehydes before and after the foaming of flexible polyurethane foam with different amine catalysts were investigated.The change in the aldehyde content of the catalyst itself during long⁃term storage,and the odors of the foams were also studied.The results showed that,due to the special ring structure and primary hydroxyl group of the catalyst RZETA,the emission of amine and aldehyde compounds was reduced,and the problem of foam odor was effectively solved.

关 键 词：反应型胺类催化剂 RZETA 泡沫气味 挥发性有机物(VOC) 醛
