Description

一种加筋复合防水卷材
技术领域
本发明涉及防水卷材生产技术领域，具体涉及一种加筋复合防水卷材。
背景技术
防水卷材是应用于铁路、公路、水利工程等领域的一种地基加固材料，防水卷材主要用于建筑墙体、屋面、以及隧道、公路、垃圾填埋场等处，起到抵御外界雨水、地下水渗漏的作用，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。现有的防水卷材在使用过程中由于强度较低，经常出现被石渣戳破，最终导致不能有效防水的问题。
发明内容
本发明提供了一种加筋复合防水卷材，以解决现有技术存在的耐戳破性能差导致不能防水的问题。
本发明解决其技术问题所采用的技术方案是：一种加筋复合防水卷材，为层状结构，包括氯化聚乙烯膜、HDPE土工膜和玻璃纤维湿法薄毡，氯化聚乙烯膜设置在HDPE土工膜顶部，玻璃纤维湿法薄毡粘结在HDPE土工膜底部，HDPE土工膜内部间隔均匀分布若干加筋绳，若干斜插钢丝设置在氯化聚乙烯膜和HDPE土工膜之间。
本发明具有以下的有益效果：
结构简单，HDPE土工膜内部间隔均匀分布若干加筋绳同时氯化聚乙烯膜和HDPE土工膜之间设置斜插钢丝，大大提高了卷材结构强度，玻璃纤维湿法薄毡具有优异的隔声、防火、防水、防霉、抗冲击、防橘皮、防开裂、耐水洗及优异的透气功效。本发明防水卷材强度高、抗拉伸能力大、抗顶破撕裂性能好、耐戳破性能好、不易被石渣戳破，能有效的防水可广泛应用于铁路、公路和水利工程中。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的一种加筋复合防水卷材结构示意图。

具体实施方式
如在说明书及权利要求当中使用了某些词汇来指称特定组件。本领域技术人员应可理解，硬件制造商可能会用不同名词来称呼同一个组件。本说明书及权利要求并不以名称的差异来作为区分组件的方式，而是以组件在功能上的差异来作为区分的准则。如在通篇说明书及权利要求当中所提及的“包含”为一开放式用语，故应解释成“包含但不限定于”。“大致”是指在可接收的误差范围内，本领域技术人员能够在一定误差范围内解决所述技术问题，基本达到所述技术效果。说明书后续描述为实施本申请的较佳实施方式，然所述描述乃以说明本申请的一般原则为目的，并非用以限定本申请的范围。本申请的保护范围当视所附权利要求所界定者为准。
如图1所示，一种加筋复合防水卷材，为层状结构，包括氯化聚乙烯膜2、HDPE土工膜1和玻璃纤维湿法薄毡3，氯化聚乙烯膜2设置在HDPE土工膜1顶部，玻璃纤维湿法薄毡3粘结在HDPE土工膜1底部，HDPE土工膜1内部间隔均匀分布若干加筋绳4，若干斜插钢丝5设置在氯化聚乙烯膜2和HDPE土工膜1之间。
作为具体的实施例，所述斜插钢丝的直径不小于2.3mm。
作为具体的实施例，所述斜插钢丝的斜插角度为与竖直方向呈25至30度。能够使得卷材抗拉伸能力大、抗顶破撕裂性能好、耐戳破性能好、不易被石渣戳破。
作为具体的实施例，沿卷材中部向左右两端的方向，相邻两个所述斜插钢丝之间的间距逐渐缩小。能够使得抗拉伸能力大、抗顶破撕裂性能好、耐戳破性能好、不易被石渣戳破。
作为具体的实施例，斜插钢丝5设置在氯化聚乙烯膜2中的插入深度小于等于在HDPE土工膜1中的插入深度。能够使得抗拉伸能力大、抗顶破撕裂性能好、耐戳破性能好、不易被石渣戳破。
作为具体的实施例，HDPE土工膜1的厚度为2.2-2.8mm，卷材结构强度更好。
作为具体的实施例，所述加筋绳为不锈钢纤维纤维制成，进一步提高卷材的结构强度。
本发明具有以下的有益效果：
结构简单，HDPE土工膜内部间隔均匀分布若干加筋绳同时氯化聚乙烯膜和HDPE土工膜之间设置斜插钢丝，大大提高了卷材结构强度，玻璃纤维湿法薄毡具有优异的隔声、防火、防水、防霉、抗冲击、防橘皮、防开裂、耐水洗及优异的透气功效。本发明防水卷材强度高、抗拉伸能力大、抗顶破撕裂性能好、耐戳破性能好、不易被石渣戳破，能有效的防水可广泛应用于铁路、公路和水利工程中。
上述说明示出并描述了本申请的若干优选实施例，但如前所述，应当理解本申请并非局限于本文所披露的形式，不应看作是对其他实施例的排除，而可用于各种其他组合、修改和环境，并能够在本文所述申请构想范围内，通过上述教导或相关领域的技术或知识进行改动。而本领域人员所进行的改动和变化不脱离本申请的精神和范围，则都应在本申请所附权利要求的保护范围内。
