| 摘 要： | 以聚已二酸乙二醇酯（PEA）、甲苯二异氰酸酯（TDI-100）、扩链剂（MoCA）、两种不同粒度分布的4A分子筛为原料，采用预聚法制备了聚氨酯／4A分子筛复合材料。考察了不同粒度的4A分子筛对Pu／4A分子筛复合材料力学性能、耐溶剂性能的影响。结果表明，Pu／4A复合材料的力学性能与分子筛的粒度密切相关，小粒度分子筛的效果优于大粒度的，且当其质量分数为7％时，所制备的PU／4A复合材料的综合力学性能最好。与纯聚氨酯相比，复合材料的耐溶剂性能大幅度提高，溶胀度减小幅度达55％～60％。

| Abstract: | The polyurethane/4A zeolite composites was prepared by pre-polymerization method,with the polyethylene glycol adipate(PEA),toluene 2,4-ditsocyanate(TDI-100),extender(MOCA) and two kinds of particles size of 4A zeolite.It was investigated that the effect of different particles size of zeolite 4A on the mechanical properties and solvent resistance of PU/4A composites.The results showed that the mechanical properties of PU/4A zeolite composites was closely related to particles size of zeolite;the smaller particles of zeolite 4A,the better the properties.And the multiple mechanical properties of PU/4A composites was best when the loading of zeolite 4A was 7%.Compared with pure PU,the solvent resistance of PU/4A composites was improved obviously. |
