摘　　要：综述了三种防水涂料的改性方法。重点介绍了丙烯酸酯类乳液防水涂料,水性聚氨酯和聚脲的反应机理及改性后材料的性能变化,用环氧树脂和有机硅等对其改性后,提高了防水涂料的拉伸强度,断裂伸长率和附着力,降低了吸水率。探讨了聚脲防水涂料的发展方向。Three kinds of modification methods for waterproof coatings are introduced. The reaction mechanism and performance change of acry- late waterproof coating, water-borne polyurethane and polyurea after modification are described in detail. After modification by using epoxy resin and organic silicon, the tensile strength, elongation at break and adhesion are improved obviously, but the water absorption decreased. The development trend of polyurea waterproof coating is also discussed.
