高密度填充型形状记忆聚氨酯泡沫的研制

Preparation of high density filling shape memory polyurethane foam

采用4,4′-二苯基甲烷二异氰酸酯(MDI)、聚己内酯二醇(PCL2000)、1,4-丁二醇(BDO)、辛酸亚锡(T-9)、食用盐等原料,通过填充法制得高密度形状记忆聚氨酯泡沫材料,表征并测试了其形貌特征、热性能、力学性能及形状记忆性能。研究结果表明:采用填充法制备高密度形状记忆聚氨酯泡沫加工工艺简单、易操作,泡沫具有高密度(0.65g/cm^3)、高压缩强度(0.37MPa)和优异的形状记忆性能。

The preparation of shape memory polyurethane foam was carried by MDI, PCL2000, BDO,T-9 and salt through the filling way. What＇s more, the morphology, thermal properties, mechanical properties and shape memory properties were tested. Research showed that the processing technology was easy, the foam had high density （0.65g/cm^3 ）, compression strength（0.37MPa） and excellent shape memory performance.
