1、单组分聚氨酯防水涂料的施工工艺周维红江苏省南通市达欣工程股份有限公司由于单组分聚氨酯防水涂膜的整体密封性好、防水层无接缝，使用简便，所以特别适用于有地下桩基础底板的防水工程；加之我国对环境保护的日益重视，单组分环保型聚氨酯防水涂料的应用推广在我国势在必行。本文通过单组分聚氨酯防水涂料特点的论述，指出了其施工工艺的要点及主要操作过程。近年来，单组分水固化聚氨酯防水涂料的研究逐渐活跃，该涂料与传统的其它聚氨酯涂料相比，具有以水为固化剂，施工方便且无毒无污染，更环保；水较其它固化剂而言，成本更低；能在较宽的温度范围内固化的优点。1、单组分聚氨酯防水涂料的特点单组分聚氨酯防水涂料在施工固化前为无定形液

2、体，对于任何形状复杂、管道纵横和变截面的基层均易于施工，形成一层柔韧、无接缝的整体涂膜防水层。固化后的单组分聚氨酯防水涂膜具有优异的物理力学性能，具有很好的弹性、拉伸性能和超乎寻常的耐低温性能，可在-59下弯曲保持不裂；与混凝土、木质、金属等基层粘结力强，其固有弹性可弥合因结构变形引起的基层裂缝。对细部节点有特殊的密封处理措施，保证了单组分聚氨酯防水涂膜防水层的整体密封。在使用时不需要现场配料，无需加入任何溶剂、不需搅拌、开盖即用，省时省工。单组分聚氨酯防水涂料根据粘度的不同分为两种类型，分别适用于垂直基层和水平基层。单组分聚氨酯防水涂料不含焦油、沥青和苯、甲苯等有害物质，是纯聚氨酯型，不污染

3、环境；而且在使用过程中不掺兑溶剂，免除了有毒溶剂对环境的污染和对人身的伤害。单组分聚氨酯涂料，分为 H 型和 V 型两种类型。水平基层表面选用H型（水平型），可自流平；垂直基层表面选用V型（垂直型），不下垂、不流淌。2、单组分聚氨酯防水涂料的施工工艺基层处理基层质量对防水工程非常关键。砂浆或混凝土找平层应抹平压光；除去基层表面浮灰和其它突出的杂物，修补抹平蜂窝、孔洞等缺陷；使基层表面达到坚实平整和充分干燥的要求，无凹凸、松动、起皮、裂缝、麻面等现象；对于基层上较为明显的裂缝，则应做附加防水处理。找平层与突出平面基层交接处的阴阳角均应做成半径为25mm 的圆弧形。基层应无油脂、灰尘杂物等影响涂膜

4、粘结的物质；干燥程度达到要求，含水率不大于9%（含水率简易测试方法：可在基层表面上干铺一块1m2 防水卷材，静置3-4h 后掀开检查，覆盖卷材部位无明显水印，文档编码:CZ9R8M7X9X4 HI6J4X1D10T5 ZJ10J6M4N5A8文档编码:CZ9R8M7X9X4 HI6J4X1D10T5 ZJ10J6M4N5A8文档编码:CZ9R8M7X9X4 HI6J4X1D10T5 ZJ10J6M4N5A8文档编码:CZ9R8M7X9X4 HI6J4X1D10T5 ZJ10J6M4N5A8文档编码:CZ9R8M7X9X4 HI6J4X1D10T5 ZJ10J6M4N5A8文档编码:CZ9R8M
