Abstract
一种设计用于结合至非PVC材料以及PVC材料的PVC基覆盖条带包括涂覆有有效防止增塑剂从PVC层迁移的隔离的PVC层。隔离层依次涂覆有底涂料并且随后涂覆有压敏粘合剂。隔离层通常是极性聚合物,例如耐邻苯二甲酸酯增塑剂迁移的丙烯腈橡胶。压敏粘合剂层是适用于屋顶应用的压敏粘合剂。
Description
背景技术
在屋顶产业中,覆盖条带通常用于将两种材料结合在一起,例如边缘条带和屋顶膜。通常,这些是涂覆有压敏粘合剂层的6至9英寸宽的膜条带。传统的PVC屋顶膜含有液体邻苯二甲酸酯增塑剂,该液体邻苯二甲酸酯增塑剂将会侵蚀屋顶市场中的许多传统压敏(PS)粘合剂。目前,没有制造商为PVC屋顶提供PS覆盖条带产品。这对于处理边缘金属是有问题的。目前,与PVC膜屋顶一起使用的所有边缘金属都必须进行PVC涂覆,以允许非PS PVC防水板焊接到金属以及PVC屋顶膜。这限制了金属可用的颜色。最后,目前还没有简单的方法将PVC屋顶膜搭接至EPDM或TPO膜而在两个膜间没有缘饰。
发明内容
本发明提供了一种底涂料和PS粘合剂的系统,其允许生产待粘附到包括PVC和KEEPVC膜、金属饰边、EPDM和TPO屋顶膜的各种基材的PS PVC覆盖条带。所提出的PS PVC覆盖条带的构造使用了一系列底涂料,这些底涂料允许普通屋顶PS粘合剂与PVC膜一起使用。第一底涂料提供了高增塑剂抗性层。这防止来自PVC膜的增塑剂侵蚀PS粘合剂。第二底涂料为PS粘合剂的粘合准备PVC表面。PS粘合剂必须充分构建为允许适应突降、长期性能、耐积水以及与其他常见的单层屋顶材料兼容。
附图说明
图1是根据本发明的覆盖条带的横截面图;
图2是用于与边缘终端一起使用的本发明的覆盖条带的横截面图;以及
图3是示出了覆盖条带在PVC膜和非PVC膜上的应用的部分分解横截面图。
具体实施方式
如图1所示,本发明是一种覆盖条带10,其包含通常用于屋顶应用类型的通常约60密耳厚的上PVC层12。PVC层12的底表面涂覆有隔离层14,该隔离层14防止增塑剂从PVC层12迁移。隔离层14又涂覆有底涂料层16,该底涂料层16又涂覆有压敏(PS)粘合剂层18。最后,PS层覆盖有硅橡胶涂覆分离片22。覆盖条带将是6-12英寸宽,通常为6-9英寸宽。
隔离层14是防止通常用于PVC膜中的邻苯二甲酸酯型增塑剂迁移的层。通常,隔离层将是极性聚合物。一种适用于本发明的极性聚合物是丙烯腈橡胶或NBR,其直接应用到表面和PVC并被允许凝固。通常这将是0.167密耳至2.5密耳厚。
底涂料的组成将由压敏粘合剂的组成决定。通常,底涂料将为0.2密耳至0.6密耳厚。压敏粘合剂可以是通常用于屋顶应用中的任何压敏粘合剂,例如溴化丁基橡胶、压敏粘合剂等。其他合适的压敏粘合剂可以是基于丁基、聚异丁烯、卤丁基或其他合适的聚合物。底涂料通常具有类似的组成,但固体含量低。底涂料被简单地应用到隔离层14并允许凝固。然后,将压敏粘合剂层18和分离片22层压至底涂料层18。
图2示出了本发明的将刚性边缘构件30应用至覆盖有PVC膜34的屋顶表面32的使用。在该应用中,将PVC膜34如通常在屋顶应用期间所做的那样应用至屋顶32。连接条带33钉固至屋顶32的角落。边缘终端条带30在一个边缘处接合至连接条带33并钉固至屋顶32,从而将PVC膜挤陷于屋顶表面和边缘处理部30之间。本应用中的边缘处理部30没有涂覆PVC涂层,反而可以是涂绘金属表面等。基本上,在此应用中,可以使用任何非PVC涂覆边缘处理部。
将覆盖条带10应用在边缘处理部30上和PVC膜34上。通常与隔离涂层14相同的条带隔离涂层36和底涂料涂层38(也与图1中的底涂料涂层16相同)应用至PVC膜34。将分离片22从覆盖条带10移除并且将覆盖条带10应用至PVC 34的隔离和底涂料涂覆部分上并直接应用到边缘处理部30的上表面40上。密封剂42可以应用在覆盖条带10的任一边缘处以提供另外的防水隔离,但不是必需的。压敏粘合剂层18将使用底涂料层38直接结合到边缘处理部的表面40并且进一步结合到涂覆有单独的隔离层36和单独的底涂料层38的PVC 34。
图3示出了本发明的另一种使用,其中覆盖条带10用于将PVC膜50结合至非PVC膜52,例如TPO,EPDM等。PVC膜50的边缘54首先涂覆有隔离层56的条带并且随后涂覆有底涂料层58。由于非PVC膜52不包含增塑剂,所以非PVC膜52不需要隔离层。但是将底涂料58的条带应用至膜52的边缘62以改善对PSA的粘合。将覆盖条带10简单地直接应用至两个膜的边缘部分。压敏粘合剂18将结附至PVC层上的底涂料层58并直接结合至非PVC膜52的表面。此外,保护覆盖条带上的压敏粘合剂免受PVC中存在的增塑剂。此外,不需要焊接来形成任何结合。
已经连同实施本发明的优选方法对本发明进行了描述。然而,本发明本身应该仅由所附权利要求限定。
