Description

一种高抗滑移预铺防水卷材及其制备方法 技术领域
本发明属于防水建筑材料技术领域，具体涉及一种高抗滑移预铺防水卷材及其制备方法。
背景技术
目前已知的高分子预铺防水卷材通常以高分子片材为载体，热熔压敏胶作为胶层，表面附上沙砾作为防粘层。该类产品相互搭接从而形成可靠的防水效果，采用预铺反粘的形式进行施工，广泛应用于地下室、地下管廊、地铁或隧道等工程领域。
然而目前高分子预铺防水卷材的片材载体通常以改性高密度聚乙烯为主，施工时直接接触水泥地面，由于高分子聚乙烯的结晶度高，摩擦系数低，导致其防水卷材的抗滑移性能差，给施工带来困难。同时使用过程中因地震等地质灾害引起的地壳运动对建筑结构的滑移破坏，无可避免地造成防水卷材的滑移错位，增加了防水卷材的应力破损和窜水的可能性。
现有技术中揭示了一些手段以提高预铺防水卷材的抗滑移性能，如在预铺防水卷材的底面设置一些凸点以提高预铺防水卷材与地面之间的防滑性能。这种方式虽能一定程度的提高抗滑移性能，但抗滑移性还是较差。
发明内容

注：表中“搭接边粘接力”指的是预铺防水卷材搭接时，具有抗滑移的下层与胶粘层之间的粘接力。
由上述表中可见，将预铺防水卷材的基材层设置为上层和下层二层结构，且下层采用具有粘滞效应的聚烯烃弹性体为主要原料制备，使得预铺防水卷材相比现有的单层结构基材层的预铺防水卷材，断裂伸长率有所提高，特别是还具有高的静摩擦系数，为预铺防水卷材提供优异地抗滑移效果，施工便捷，并且具有优异的力学性能及具有较大的与搭接边的粘接力。再者基材层的上层和下层共挤制备，预铺防水卷材加工工 艺简单。
