非沥青基防水卷材的防水原理是怎样的?

   2024-09-24 1110

非沥青基防水卷材的胶料为非沥青基强力自粘密封胶不含沥青成分,克服了沥青类胶料在环境改变的条件下易老化、脆裂、粘结不牢等不利条件具有超强的粘结力、抗老化、双向抗撕裂等物理特性。

非沥青基防水卷材表面高分子片材由高分子原料反应而成具有随形的蠕变和渗透功能,能与液态混凝土浆料反应固结形成防水层与混凝土结构无间隙结合,有效地提高防水的可靠性,符合现代节能环保的建筑理念。

因为非沥青基防水卷材优异的物理性能和与混凝土固结反应的化学性能卷材施工基面要求低,且基面不需干燥,雨季基面湿润亦可施工,卷材施工完成可直接在其表面绑扎钢筋不需设置混凝土保护层,所以采用这种防水卷材能有效地缩短地下室底板防水施工工期,同时可提高防水质量。
