摘　　要：通过调整催化剂三乙烯二胺溶液和二月桂酸二丁基锡的用量进行浇注试验。结果表明,室温浇注泡沫塑料的性能(密度、压缩强度、闭孔率、拉伸强度、热导率、等效热导率、线胀系数)与低温浇注泡沫塑料的性能相当,实现了聚氨酯泡沫塑料的室温浇注。Pouring experiments were conducted by adjusting the dosage of TEDA solution and DBTL in the rigid polyurethane plastic foam pouring formulation.The properties of two kinds of plastic foams manufactured at the material temperature of room temperature and 5℃ were compared.The mechanical properties,closed cell proportion,liner expansion coefficient and thermal conductivity have the equal values at room temperature and 5℃.So the pouring process at the material temperature of RT is feasible.
