Description
技术领域
本发明属于工程保温隔热领域，尤其涉及一种铝箔玻纤布及其制备方法。
背景技术
在国家“节能减排”国策推动下，各个领域对保温隔热、节能的要求越来越高。铝箔玻纤布拥有很好的反射性能，可以有效的解决热量传递过程中占主导的热辐射损失，节能效果显著。
目前一些常规的同类产品耐温性较低，一般是用聚乙烯热压复合，然后用作保温材料的贴面。在一些高温场合，例如高温蒸汽管道，对铝箔玻纤布的耐温性有很高的要求，常规的产品无法实现，同时常规产品的结构单一，成卷包装，不便于现场施工，尤其是保温管道的施工，现场保温工作量大，材料浪费多，包裹形式复杂而不牢固、在现场受潮易腐蚀、不透气导致保温材料中的湿气无法散出，保温质量得不到保证。
发明内容
本发明的目的在于提供一种铝箔玻纤布及其制备方法，旨在解决现有铝箔玻纤布耐温性差、防腐蚀性差、透气性差、不便于现场施工的问题。
本发明是这样实现的，一种铝箔玻纤布包括铝箔和玻纤布，该铝箔和玻纤布通过阻燃胶黏剂复合而成，铝箔表面镀有SiO2涂层，铝箔玻纤布中设有贯通铝箔、玻纤布、SiO2涂层的透气孔，铝箔玻纤布两端用玻璃纤维线缝制卡扣。
进一步，铝箔为压延单面光铝箔，该压延单面光铝箔的厚度为6.5～20um，玻纤布采用中碱玻纤布。
进一步，阻燃胶黏剂为水溶性胶，其质量组分为：苯乙烯10%～30%、交联剂0.3%～0.6%、丙烯酸酯35%～50%、乳化剂0.1%～1.5%、乙酸乙烯酯12%～20%、蒸馏水2%～5%，阻燃胶黏剂的用量为8 g/m2～30g/m2。
进一步，SiO2涂层的厚度为0.05 um～0.08um。
进一步，透气孔为方形阵列布置，孔径6mm，相邻透气孔的中心距为100mm。
进一步，两端设有两对卡扣，用玻璃纤维线缝制在铝箔玻纤布上，卡扣宽度为50mm。
进一步，铝箔玻纤布成品的宽度为0.5m，长度为管道保温外表面圆周长C的0.95倍再加50mm后取整。
进一步，根据原料配比的不同，铝箔玻纤布可分为普通型、耐中温型、耐高温型和耐超高温型。
普通型：铝箔8%～10%、玻纤布82%～86%、阻燃胶黏剂6%～8%、SiO2涂层0.3%～0.5%。
耐中温型：铝箔12%～15%、玻纤布78%～83%、阻燃胶黏剂8%～10%、SiO2涂层0.4%～0.6%。
耐高温型：铝箔13%～16%、玻纤布76%～80%、阻燃胶黏剂9%～11%、SiO2涂层0.5%～0.7%。
耐超高温型：铝箔15%～18%、玻纤布74%～78%、阻燃胶黏剂10%～12%、SiO2涂层0.6%～0.8%。
本发明的另一目的在于提供一种铝箔玻纤布的制备方法，具体包括：
步骤一、采用洗涤法将玻纤布表面的残留物去除；
步骤二、采用热复合机将铝箔与玻纤布通过阻燃胶黏剂进行热复合，复合温度为180℃，复合速度控制在5～30m/min；
步骤三、在铝箔反射面高压电镀一层SiO2涂层；
步骤四、在铝箔玻纤布上进行打孔；
步骤五、按要求将铝箔玻纤布分切成指定的规格，用缝纫机将分切后的铝箔玻纤布两端通过玻璃纤维线缝制卡扣。
本发明的铝箔玻纤布，在提升了其本身特性的同时，将其定位成一种定制产品，长度、宽度根据不同项目的实际情况而定，独特的结构形式使得现场保温施工极其方便，节省了材料的使用量，也使得保温表面平整均匀，保温质量得到了保证，也提高了整体节能效果，社会经济效益显著。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
下面结合附图对本发明的结构作详细的描述。
图1为本发明所述铝箔玻纤布的长度方向侧视图。
如图1所示：铝箔1的非光面与玻纤布2通过阻燃胶黏剂3复合，铝箔1光面镀有SiO2涂层4，铝箔玻纤布上阵列布置了直径6mm的透气孔5，铝箔1长度方向两端用玻璃纤维线7缝制了卡扣6。铝箔玻纤布的长度为管道保温外表面圆周长C的0.95倍再加50mm后取整。
图2为本发明所述铝箔玻纤布的宽度方向侧视图。
铝箔玻纤布的宽度为500mm，卡扣6宽度为50mm，卡扣6中心距铝箔玻纤布边缘的距离为100mm，卡扣6之间的中心距为300mm。
图3为本发明所述铝箔玻纤布在管道保温结构中使用示意图。
如图3所示：管道8规格为Φ530×10mm，管道输送蒸汽，介质温度为350℃，保温层9共4层，每层厚度为50mm，每一层管道保温层外包裹一层铝箔玻纤布，最外层包裹彩钢板14。
耐超高温型铝箔玻纤布10的长度L1：
3.142×(530+50×2)×0.95+50=1930.487mm
L1的取值为1930mm。
耐超高温型铝箔玻纤布11的长度L2：
3.142×(530+50×2+50×2)×0.95+50=2228.977mm
L2的取值为2230mm。
耐超高温型铝箔玻纤布12的长度L3：
3.142×(530+50×2+50×2+50×2)×0.95+50=2527.467mm
L3的取值为2530mm。
耐超高温型铝箔玻纤布13的长度L4：
3.142×(530+50×2+50×2+50×2+50×2)×0.95+50=2825.957mm
L4的取值为2830mm。
因管道输送介质温度较高，管道运行时会发生热膨胀，铝箔玻纤布在包裹后，环向纵向预留搭接缝。卡扣6卡住后，铝箔玻纤布包裹在管道8上的纵缝搭接长度为50mm；相邻两块铝箔玻纤布之间的环缝搭接长度也为50mm。
管道长度较长、保温层数多、彩钢板施工不能立即跟上，为防止雨水进入保温层，卡扣6设置在圆周竖直方向45度范围内。
常规的同类反射产品，在包裹管道时一般采用的是成卷缠绕包裹，每个一定距离用铁丝捆扎，施工不方便、材料浪费大、铁丝捆紧后会造成其表面不平整、甚至出现缝隙，影响保温隔热效果。
具体实施案例：以20km长的DN500蒸汽管道为例，常规缠绕法的铝箔玻纤布施工周期大概要3个月左右，本发明的铝箔玻纤布施工周期仅需40天左右；常规铝箔玻纤布的用量约28万平米，本发明的铝箔玻纤布用量仅需21万平米，节省材料约25%；本发明的铝箔玻纤布在实际使用过程中，可将常规铝箔玻纤布保温结构的散热损失再减少5～10%。
本发明的铝箔玻纤布，在提升了其本身特性的同时，将其定位成一种定制产品，长度、宽度根据不同项目的实际情况而定，独特的结构形式使得现场保温施工极其方便，节省了材料的使用量，也使得保温表面平整均匀，保温质量得到了保证，也提高了整体节能效果，社会经济效益显著。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
