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.
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.
