Description

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，在高阻隔薄膜的两侧分别采用粘结剂复合一层玻璃纤维布，形成二层玻璃纤维布复合膜。
所述的粘结剂为溶剂型或水性胶；所述的高阻隔薄膜为铝箔、镀铝膜、PET薄膜、尼龙薄膜、PVC薄膜、PE薄膜、EVOH薄膜或PP薄膜。
所述的二层玻璃纤维布复合膜的复合方法是：用胶辊将粘结剂涂抹在高阻隔薄膜的一侧，通过电加热或热风干燥的形式，将粘结剂中多余的溶剂或水份排掉后，用加热挤压的方式将上述薄膜与玻璃纤维布复合在一起，成为铝箔玻璃纤维布、镀铝玻璃纤维布、PET玻璃纤维布、尼龙玻璃纤维布、PVC玻璃纤维布、PE玻璃纤维布、EVOH玻璃纤维布或PP玻璃纤维布；通过与上述同样的方法在高阻隔薄膜的另一侧复合一层玻璃纤维布，制得含有双层玻璃纤维布的铝箔玻璃纤维布、镀铝玻璃纤维布、PET玻璃纤维布、尼龙玻璃纤维布、PVC玻璃纤维布、PE玻璃纤维布、EVOH玻璃纤维布或PP玻璃纤维布，统称为二层玻璃纤维布复合膜。
所述的二层玻璃纤维布复合膜与一种阻隔复合膜，通过粘合剂复合，且阻隔复合膜在内侧。
所述的阻隔复合膜由铝箔、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。
在所述的阻隔复合膜的最内层设有PE膜，且该阻隔复合膜中各层膜的复合工艺与所述的高二层玻璃纤维布复合膜的复合方法相同。
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，在高阻隔薄膜的两侧用粘结剂复合二层玻璃纤维布复合膜。
所述的粘结剂为溶剂型或水性胶（如北京高盟公司的3166溶剂型胶, 上海拜尔的7132水性胶）；所述的高阻隔薄膜为铝箔、镀铝膜、PET薄膜、尼龙薄膜、PVC薄膜、PE薄膜、EVOH薄膜或PP薄膜。
二层玻璃纤维布复合膜具体的复合方法是：用胶辊将粘结剂涂抹在铝箔、镀铝膜、PET薄膜、尼龙薄膜、PVC薄膜、PE薄膜、EVOH薄膜或PP薄膜的一侧，通过电加热或热风干燥的形式，将粘结剂中多余的溶剂或水份排掉后，用加热挤压的方式将上述薄膜与玻璃纤维布复合在一起，成为铝箔玻璃纤维布、镀铝玻璃纤维布、PET玻璃纤维布、尼龙玻璃纤维布、PVC玻璃纤维布、PE玻璃纤维布、EVOH玻璃纤维布或PP玻璃纤维布，通过与上述同样的方法在铝箔、镀铝膜、PET薄膜、尼龙薄膜、PVC薄膜、PE薄膜、EVOH薄膜或PP薄膜的另一侧复合一层玻璃纤维布，制得含有双层玻璃纤维布的铝箔玻璃纤维布、镀铝玻璃纤维布、PET玻璃纤维布、尼龙玻璃纤维布、PVC玻璃纤维布、PE玻璃纤维布、EVOH玻璃纤维布或PP玻璃纤维布，统称为二层玻璃纤维布复合膜。
所制得的二层玻璃纤维布复合膜在用作抽真空绝热板封皮料时需与阻隔复合膜通过粘合剂进行复合，且阻隔复合膜在内侧。复合工艺与所述的高阻隔薄膜与玻璃纤维布的复合方法相同。
所述的阻隔复合膜为铝箔、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通过粘合剂进行复合，在复合膜的最内侧设有PE膜。复合工艺与所述的高阻隔薄膜与玻璃纤维布的复合方法相同。
所述的玻璃纤维布的规格为50-500g/m2。
