液态MDI制备与应用

Preparation and Application of Liquid MDI

本文介绍以纯MDI为基础原料,使用低分子量二元醇进行氨酯改性和使用有机磷化氧为催化剂进行碳化二亚胺/二氮环丁酮亚胺改性,制备液态MDI。使用碳二亚胺改性产物进行冷固化工艺发泡实验,制备高回弹泡沫塑料。

In the present paper we were primarily concerned with preparation and appli- cation of carbodiimide/uretonimine—containing adducts as new liquid diphenylmethane diisccyanate,and the use of its adducts for prepartion of high resilience"Cold—Cured"polyurethane foam。
