用于真空绝热板的高阻隔复合膜及其制造方法
技术领域
本发明涉及一种用于抽真空的保温板的封皮料，具体是一种高阻隔复合膜及其制造方法。
背景技术
现有抽真空绝热板高阻隔薄膜主要由铝箔、PET薄膜、尼龙薄膜  、PE薄膜或PP薄膜制成，其缺点是存在怕划伤，怕刺穿，与水泥砂浆粘结不牢，不抗老化、不耐碱等问题。在施工中一旦被刺穿，则不仅大大降低隔热性能，并使整个保温层的结构受到破坏。
发明内容
本发明旨在提供一种用于真空绝热板的高阻隔复合膜及其制造方法，以解决现有真空绝热板用于建筑的粘结、老化、划伤、刺穿等一系列问题。
本发明的技术方案是：一种用于真空绝热板的高阻隔复合膜，其特征在于，在高阻隔薄膜的最外侧通过流延的方式复合二层玻璃纤维布。
所述的高阻隔薄膜为PET薄膜、尼龙薄膜、PVC薄膜、EVOH薄膜、PE薄膜或PP薄膜；所述的二层玻璃纤维布之间用PET薄膜、尼龙薄膜、PVC薄膜、EVOH薄膜、PE薄膜或PP薄膜，通过流延的方式相互复合形成双层玻璃纤维布流延复合膜”。
所述的双层玻璃纤维布流延复合膜的复合方法是：通过薄膜流延机，以单层流延或多层共挤流延形式制成单层流延膜或多层共挤流延膜，且制膜的同时将其流延在二层玻璃纤维布之间，形成双层PET流延玻璃纤维布、双层尼龙流延玻璃纤维布、双层PVC流延玻璃纤维布、双层EVOH流延玻璃纤维布、双层PE流延玻璃纤维布或双层PP流延玻璃纤维布，统称为双层玻璃纤维布流延复合膜。
所述的双层玻璃纤维布流延复合膜与一种阻隔复合膜复合形成高阻隔复合膜，复合工艺为常规干法或湿法复合，形成的层结构是：从外向内依次是双层玻璃纤维布流延复合膜、阻隔复合膜。
所述的常规阻隔复合膜由铝箔、镀铝膜、PET薄膜、尼龙薄膜、PVC薄膜、EVOH薄膜或PP薄膜中的一种或一种以上的任意组合进行复合。
在所述的常规阻隔复合膜的最内层设有PE膜，且常规阻隔复合膜中各层膜的复合工艺为常规干法复合工艺。
所述的玻璃纤维布的规格为50-500g/m2。
本发明的优点是：在真空绝热板的原有高阻隔薄膜的最外侧复合二层玻璃纤维布，利用玻璃纤维布与水泥的优良亲和性和抗划伤性能，可以有效解决常规真空绝热板高阻隔薄膜存在的怕划伤、怕刺穿、与水泥砂浆粘结不牢、不抗老化的问题，解决了现有真空绝热板用于建筑上的老大难问题。
具体实施方式
 本发明是一种用于真空绝热板的高阻隔复合膜及其制造方法，在现有真空绝热板封皮料外侧用流延的方式复合有双层玻璃纤维布流延复合膜。
