不同催化剂在常温下对聚氨酯泡沫的催化活性研究

Study on the Catalytic Activity of Different Catalysts on Polyurethane Foam at Room Temperature

汽车座椅软泡在工艺生产中一般都是在低温模具内(60℃左右)进行泡沫的发泡工艺,但是在常温状态下不能生产熟化良好的泡沫。本文研究了在常温状态下市面上几种常用的催化剂对泡沫熟化的催化效率,以期找到一个能在常温下表现良好的催化剂,进行泡沫的生产。

In the process of production of car seat soft foam, the foaming process is generally carried out in a low-temperature mold (about 60˚C), but it cannot produce well-matured foam at room temperature. This paper studies the catalytic efficiency of several commonly used catalysts on the market for foam maturation at room temperature, in order to find a catalyst that can perform well at room temperature for foam production.
