Description
技术领域
本发明涉及防水建材技术领域，特别是一种荧光制冷TPO防水卷材及其制备方法。
背景技术
根据相关统计，我国90％以上的建筑墙体都存在漏水现象。目前，在屋面防水设计选择上，往往使用防水卷材进行防水处理，且防水卷材是整个防水工程的第一道屏障，对整个防水工程起着至关重要的作用。
随着能源紧缺现象的产生、环保压力的日益加大，节能减排已迫在眉睫，冷屋面系统即属于建筑节能的重要措施之一。根据美国环境保护署估计，每年用于商业建筑的制冷费用约为400亿美元，而一个好的冷屋面系统每年可以节约空调费约达10％-40％。
现阶段建筑墙体在使用过程中存在的主要问题是：第一，都或多或少的存在漏水现象。第二，性能优越的防水材料较少。第三，在屋面防水设计选择上，通常只能选择防水卷材进行防水处理。第四，随着能源紧缺现象的产生、环保压力的日益加大，节能减排已迫在眉睫，冷屋面系统即属于建筑节能的重要措施之一。第五，现有的环保制冷费用昂贵。

步骤4，增强型荧光制冷TPO防水卷材制备：将步骤2中获得的粒料加入单螺杆片材挤出生产线中挤出成片，制备荧光制冷TPO片材，之后与网格布在三辊轧光机上进行热压复合，随后经冷却、纠偏、裁边、收卷包装。
进一步，三辊轧光机热压复合温度为180-220℃。
进一步，荧光制冷TPO防水卷材厚度为1-3mm。
本发明的有益效果体现在：
1，本发明提供的一种荧光制冷TPO防水卷材及其制备方法，在TPO防水卷材中引入制冷体，利用荧光制冷和辐射制冷原理，赋予防水卷材制冷功能，具有良好的降温效果，尤其在烈日炎炎的夏天，可大幅降低室内温度，有利于减少空调使用，节能环保。

将步骤1中的得到的混合料加入双螺杆挤出机中进行熔融共混，挤出造粒并在60℃下烘干6-12h；其中塑化温度为180-220℃；
步骤3，均质荧光制冷TPO防水卷材制备：将步骤2中获得的粒料加入单螺杆片材挤出生产线中挤出成片，并经三辊轧光机轧光，复合温度为180-220℃；随后经冷却、纠偏、裁边、收卷包装成均质荧光制冷TPO防水卷材；其中，塑化挤出温度为180-220℃；
步骤4，增强型荧光制冷TPO防水卷材制备：将步骤2中获得的粒料加入单螺杆片材挤出生产线中挤出成片，制备荧光制冷TPO片材，之后与网格布在三辊轧光机上进行热压复合，随后经冷却、纠偏、裁边、收卷包装。荧光制冷TPO防水卷材厚度为1-3mm。
实施例2
一种荧光制冷TPO防水卷材及其制备方法，同实施例1，不同之处在于：所述防水卷材包括两层均质荧光制冷TPO防水卷材，以及设置在两层均质荧光制冷TPO防水卷材之间的网格布增强层。参见图3所示。
在制备上的不同在于：将上述荧光制冷TPO片材、网格布及荧光制冷TPO片材在三辊轧光机上进行热压复合，形成上层为均质荧光制冷TPO防水卷材、中层为网格布增强层、下层为均质荧光制冷TPO防水卷材。
对实施例2得到的防水卷材进行性能表征测试，具体可以参见图2墙体温度变化曲线。由图2可以得到：
第一，观察待测墙体温度变化周期为7天；
第二，未铺设防水卷材的墙体温度在一天的同时间段内始终高于铺设普通TPO防水卷材的墙体温度；
第三，铺设了实施例1中的防水卷材的墙体温度相对稳定，维持在23-26℃之间。
由此可以知道，如图2所示，TPO防水卷材与普通TPO防水卷材相比较，本实施例2提供的TPO防水卷材具有很好的制冷效果。TPO防水卷材中引入荧光制冷体和辐射制冷体。其中，荧光制冷体基于反斯托克斯原理制备实现制冷；辐射制冷体将太阳光能以8-13μm电磁波的形式通过“大气窗口”排放到温度接近绝对零度的外部太空，实现制冷。
实施例3
一种荧光制冷TPO防水卷材及其制备方法，同实施例2，不同之处在于：防水卷材由上至下依次为上层均质荧光制冷TPO防水卷材、中层为网格布增强层、下层为普通均质TPO防水卷材。
表1实施例1-3各组分明细
本发明提供的一种荧光制冷TPO防水卷材及其制备方法，在TPO防水卷材中引入制冷体，利用荧光制冷和辐射制冷原理，赋予防水卷材制冷功能，具有良好的降温效果，尤其在烈日炎炎的夏天，可大幅降低室内温度，有利于减少空调使用，节能环保。铺设防水卷材的墙体温度相对稳定，维持在23-26℃之间。
以上所述仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内所想到的变化或替换，都应涵盖在本发明的保护范围之内。
