摘　　要：研究了不同类型自粘防水卷材与单组分聚氨酯防水涂料干膜、湿膜的粘结剥离情况,结果表明:短时间内,干膜粘结效果优于湿膜粘结,改性沥青自粘防水卷材与单组分聚氨酯防水涂料的粘结效果优于高分子自粘卷材;由于单组分聚氨酯防水涂料中存在的游离成分会渗入自粘防水卷材,影响两者的相容性,实际工程应用中不建议采用单组分聚氨酯防水涂料和自粘防水卷材的搭配做法。The bonding and peeling properties between different types of self-adhesive waterproofing membrane and the dry and wet films of single component polyurethane waterproofing coating are studied.The results show that in a short period of time,the adhesion effect of dry film is better than that of wet film,and the adhesion effect of modified bitumen self-adhesive waterproofing membrane and single component polyurethane waterproofing coating is better than that of polymer self-adhesive membrane;since the free components in single component polyurethane waterproofing coatings can penetrate into self-adhesive waterproofing membrane and will affect their compatibility,it is not recommended to use a combination of single component polyurethane waterproofing coating and self-adhesive waterproofing membrane in practical engineering applications.
