Description

金刚砂HDPE自粘胶膜双层交叉反粘结防水卷材
技术领域
本发明涉及防水卷材技术领域，具体的说是一种金刚砂HDPE自粘胶膜双层交叉反粘结防水卷材。
背景技术
防水卷材是建筑施工中常用的一种可卷曲成卷状的柔性建筑材料，在道路、桥梁、隧道、屋顶或其它需要防水、防渗的建筑物的施工中，均需要预先铺制防水卷材，从而起到起到抵御外界雨水、地下水渗漏的目的，防水卷材作为工程基础与建筑物之间无渗漏连接，是整个工程防水的第一道屏障，对整个工程起着至关重要的作用。随着建筑行业的快速发展与防水行业的蓬勃发展，建筑工程中用到的防水材料需求量也越来越大，从而产生层出不穷的HDPE防水卷材，然而这些HDPE防水材料卷材仍旧存在着如下缺陷：
1、适应基层变形能力差，断裂延伸率差；
2、施工受天气等外界因素影响大，施工自由度低，工期过长；
3、耐盐碱腐蚀性能和抗氯离子渗透性差，在长时间处于高盐碱环境中时防水性能明显下降，从而失去保护作用，不能很好地保护建筑结构不受腐蚀，影响了建筑物的使用寿命；
4、在低温地区特别是冬季无法施工，产品无法开卷、展平，由于天气、温度等原因无法粘结到一起。
综上所述，针对现有技术的缺陷，我们提出一种金刚砂HDPE自粘胶膜双层交叉反粘结防水卷材，从而解决以上提到的问题。
发明内容
