Description

交叉层压膜预铺防水卷材
技术领域
本发明涉及交叉层压膜预铺防水卷材。
背景技术
防水卷材主要是用于建筑墙体、屋面、以及隧道、公路、垃圾填埋场等处，起到抵御外界雨水、地下水渗漏的一种可卷曲成卷状的柔性建材产品，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。
现有防水卷材有如下缺陷：
1、胶层粘接性能差，经短时间外露曝晒，粘接性能丧失，沥青基卷材问题尤为突出。
2、材料铺贴不平服，会有空铺起鼓的问题。
3、立面固定不灵活，现有的预铺类材料，在立面固定需采用大量辅材和射钉。
发明内容
为了解决现有技术中的缺陷，本发明提供一种交叉层压膜预铺防水卷材，包括由上至下依次层叠的：
砂粒层，
第一改性沥青胶粘层，
高分子强力交叉压膜层，
第二改性沥青胶粘层，
以及PE隔离膜层；
防水卷材的一侧还设有搭接边，搭接边处砂粒层空缺。
优选的，所述砂粒层采用经过碳化和钙化处理的人工合成砂。
优选的，所述高分子强力交叉压膜层，其由4层高强度PE膜交叉叠压复合而成。
优选的，所述第一改性沥青胶粘层和第二自改性沥青胶粘层，按重量份计由以下组分组成：
55份70#沥青，
8份软化油，
12份SBR，
9份SBS，
9份增粘树脂，
7份填充料。
优选的，所述软化油为减二线油。
优选的，所述增粘树脂为C5石油树脂。
优选的，所述填充料为200目的石粉。
本发明交叉层压膜预铺防水卷材，其每层结构的具体作用如下：
砂粒层：1）防粘，防止后续工序施工时粘脚；2）抵抗紫外线影响第一改性沥青胶粘层、第二改性沥青胶粘层的粘结性能。
第一改性沥青胶粘层、1）作为粘结层，与后浇混凝土粘结；2）作为防水层，利用沥青良好的防水性能。
高分子强力交叉压膜层：提供防水卷材优异的物理性能，如拉伸强度、延伸率、尺寸稳定性等。
第二改性沥青胶粘层：作为防水层，利用沥青良好的防水性能。
PE隔离膜层：隔离第二改性沥青胶粘层，避免污染。
砂粒层采用人工合成砂，经过碳化、钙化、表面糙化处理及筛分之后，具有高强度、级配合理的特性，有效抵抗紫外线，保证第一改性沥青胶粘层、第二改性沥青胶粘层的粘结强度。
第一改性沥青胶粘层、第二改性沥青胶粘层通过配方调整，可抵抗太阳光紫外线对粘结性能的影响，确保粘结强度。
本发明交叉层压膜预铺防水卷材，极其适用于预铺部位防水，及外防内贴侧墙防水，如地下工程底板、垂直开挖的地下工程侧墙；同时也可用于其他后铺部位防水，如地下室顶板、屋面。
本发明交叉层压膜预铺防水卷材，预铺反粘工艺施工，可与后浇混凝土紧密粘合，消除防水层与混凝土结构之间的窜水层，可有效抵抗紫外线、泥沙污染对粘结性能的影响，施工完成后不会因昼夜温差变化而导致卷材起鼓起皱，铺贴平服，搭接边不易脱开，相较于传统做法，本发明材料用于预铺部位防水施工时可节约工程造价、节省工期、提升防水质量。
本发明交叉层压膜预铺防水卷材相较于现有防水卷材的优势如下：
1、现有防水卷材的胶层粘接性能差，经短时间外露曝晒，粘接性能丧失，沥青基卷材问题尤为突出。本发明交叉层压膜预铺防水卷材，采用人工合成砂，砂颗粒采用最合理的级配，表面糙化处理，有效降低紫外线对自粘橡胶沥青的影响。
2、现有防水卷材铺贴不平服，会有空铺起鼓的问题。本发明交叉层压膜预铺防水卷材，用于预铺部位一般采用空铺施工，相较于其他预铺类材料，本发明材料柔软度好，尺寸稳定性优异，解决了空铺起鼓的问题。
3、现有防水卷材的立面固定不灵活，现有的预铺类材料，在立面固定需采用大量辅材和射钉。本发明交叉层压膜预铺防水卷材，双面均有自粘橡胶沥青，在立面需要固定时揭除隔离膜可直接粘贴于基层上。
