摘　　要：以异佛尔酮二异氰酸酯(IPDI)、聚醚三元醇(330N)为原料,异丙醇为溶剂,亚硫酸氢钠(NaHSO3)为封端剂,通过预聚、封端及自乳化等阶段合成了一种封端型水性聚氨酯交联剂。将该交联剂用于棉织物涂料印花,测试结果表明,印花织物的干、湿摩擦牢度及耐皂洗牢度均得到了有效提升。The cross-linker of blocked waterborne polyurethane was prepared by polymerization,end-capping and self-emulsification using isophorone diisocyanate（IPDI）and polyether triol（330N）as raw materials,isopropyl alcohol as solvent and sodium bisulfite（NaHSO3）as capping agent.The test results showed that it could effectively improve the rubbing fastness and washing fastness of pigment printing.
