摘要
研究了以聚酯多元醇和异氰酸酯为主原料，采用水基发泡新工艺制取软质聚氨酯泡沫的配方。讨论了ＮＣＯ指数、发泡剂用量对泡沫性能的影响。为开发无氟里昂发泡技术提供了实验参数。
A formula has been developed for making the soft polyurethane foamed plastic with polyester polylol and isocyanate as the raw materials by a new water foamed technology. The effects of the NCO index and the quantity of foaming agent on the blowing character were investigated.
