摘要
介绍了用于聚氨酯泡沫塑料的几种环境友好的发泡剂,包括水、液态CO2、戊烷系列、氢氟碳化合物(HFC)、氟代烯化合物(HCFO)、利用疏水改性聚乙烯亚胺可逆吸收并释放CO2的发泡剂,还介绍了真空/减压发泡技术,简单讨论了它们的优缺点。
Six kinds of environment-friendly polyurethane blowing agents were introduced, including water, liquid carbon dioxide, pentanes, hydrofluorocarbons （HFCs） , hydrofluoroolefins （HCFOs） and CO2 adducts from hydrophobieally modified polyethyleneimines. Vacuum （reduced pressure ） foaming process was also introduced. Their advantages and disadvantages were briefly discussed.
