| 摘 要： | 以聚对苯二甲酸乙二醇酯（PEA）、甲苯二异氰酸酯（TDI-80）、扩链剂（MOCA）、分子筛为原料，采用预聚体法制备了聚氨酯／分子筛复合材料．考察了分子筛的种类及加入量对聚氨酯／分子筛复合材料的耐溶剂性能、力学性能及热分解温度的影响．结果表明：在相同加入量的前提下，采用4A和13X分子筛制备的复合材料，前者的耐溶剂性能及力学性能要优于后者，当加入量为5％时，性能达到最佳．两者的加入均能提高复合材料的热分解温度，但影响相差不大． |

| Abstract: | The polyurethane/zeolite composites was prepared by pre-polymerization method,with the polyethylene glycol adipate(PEA),toluene ditscoyanate(TDI-80),extender(MOCA)and zeolite.It was investigated that the effect of the kinds of zeolite on the mechanical properties and solvent resistance of PU/zeolite composites.The results showed that the mechanical properties and solvent resistance of PU/4A zeolite composites was better than PU/13X zeolite composites under the same addition of zeolite.And the properties of PU/zeolite composites was best when the loading of zeolite was 5%.Compared with pure PU,the thermal stability of PU/zeolite composites was improved. |
