摘　　要：以异佛尔酮二异氰酸酯(IPDI)、聚醚(N-220)等为主要原料,通过在后扩链中加入不同比例的小分子氨基硅油而合成一系列稳定的氨基硅油改性水性聚氨酯乳液。经测试研究表明,氨基硅油的加入可以显著提高水性聚氨酯的耐水性能,对于力学性能没有太大影响。PDI and N-220 are used as materials and different ratio of small molecule amino silicone oil is used in after chain extension to give a series of small molecule amino silicone oil modified water-borne PU latexes. Test results show that the modification can significantly improve the water-resistance of water-borne PU and has no influence on the mechanical property.
