摘要

通过二乙醇胺（DEA）和二氧化碳反应制得一种氨基甲酸铵化合物（DEAC）。DEAC初始分解温度约为54℃，二氧化碳含量14.6%。将不同份数的DEAC作为反应型发泡剂添加到硬质聚氨酯发泡体系中制备泡沫材料，得到密度为90~150 kg·m-3，压缩强度为0.02~1.65 MPa性能良好的泡沫材料。DEA在火力发电厂作为二氧化碳吸收剂以减少二氧化碳排放。因此，DEAC可以来源于火力发电厂的副产物，成本低廉。本研究为硬质聚氨酯泡沫的制备提供了一种新型的绿色、环保、经济的方法。

Abstract

Diethanol ammonium carbamate (DEAC) was prepared by reaction of diethanolamine (DEA) with carbon dioxide. DEAC has onset decomposition temperature round 54℃. Addition of DEAC as reactive blowing agent into common rigid polyurethane foaming formulation gave foams with densities in the range of 90 to 150 kg·m-3 and compressive strengths in the range of 0.02 to 1.65 MPa. DEA can be used as CO2 absorbents in coal-burn power generation plant to reduce greenhouse gas emission. DEAC can be obtained as byproduct from coal-burn power station with low cost. This novel approach is environmentally friendly

cost effective and promising to open up a new platform for green foaming of polyurethanes.
