Abstract
本发明涉及一种使膨胀纸质蜂巢状芯层材料防潮或防水的方法,以及应用本方法获得的蜂巢状芯层材料。根据本发明,对膨胀后的蜂巢状芯层材料进行涂敷,涂层优选以一种聚合物塑料的粉末施涂。
Description
本发明涉及一种使膨胀的纸质蜂巢状芯层材料防潮或防水的方法，以及使用这种方法获得的蜂巢状芯层材料。
纸质蜂巢状芯层材料常常用作一种韧性的轻型建筑材料。在许多应用中，纸质蜂巢状芯层材料必须是防潮或防水的，例如外部使用的建筑镶板，运输或楼板使用的建筑板材等。在这些情况当中，蜂巢状芯层材料通常以防潮和防水的条件交货，然后用户自己在蜂巢状芯层材料的一侧或两侧加上一层例如是塑料或金属的外壳。
纸质蜂巢状芯层材料是通过在特定位置将一些纸束相互胶结，待胶水干燥之后，横向拉伸外侧纸束，使整个纸体膨胀，从而获得六角形蜂窝状结构。当膨胀的形状稳定之后，蜂巢状芯层材料被切成所需厚度的薄片，进一步作为例如蜂巢状板材的蜂巢状芯层。
已知可以通过浸渍膨胀后的纸体制造防潮和防水的纸质蜂巢状芯层材料。浸渍是通过将膨胀的蜂巢状芯层材料浸入甲醛水溶液中完成的。在这种已知的过程中浸渍通常进行许多次，以便涂敷上所需量的树脂。浸渍之后，浸渍的蜂巢状芯层材料必须借助干燥装置干燥，以除去蜂巢状芯层材料中的多余水份。
这种使纸质蜂巢状芯层材料防潮和防水的方法有一些缺点。甲醛是一种有毒物质，回收与排放困难。由于浸渍必须进行多次的事实，处理既费时又费力，导致很高的加工费用。在本工艺结束时的干燥是一个额外步骤，其中含甲醛蒸汽的溶剂必须以一种安全的方式除去。
本发明的目的是提供一种克服上述缺点的，使得膨胀的纸质蜂巢状芯层材料防潮防水的方法。
根据本发明，其目的是通过蜂巢状芯层材料膨胀后施加涂层来实现的。
由此产生具有防潮和防水作用的密封层的纸质蜂巢状芯层材料。这种涂层可以采用一层，由此避免了重复浸渍。甲醛也就不再必须使用了。通过施加这种涂层，获得一种涂层—纸—涂层的夹层结构，它产生一种比浸渍纸更轻更结实的结构。这种方法比那种在相互粘结和膨胀之前就已将纸束涂覆的方法便宜，因为所需涂料较少，粘结区域无涂料，且可以使用普通粘结剂。此外，由于还未对生产期间产生的蜂巢状芯层材料废品施加使***格上涨的涂料，所以费用得到了节省。
涂料最好使用粉状聚合物材料，因为用这种方法，可以在短时间内在整个蜂巢状组织长度上涂覆基本均匀厚度的涂层。
在这种方法的有利的实施方案中，粉末是以向纸质蜂巢状芯层材料和粉末施加相反电荷来施涂的。通过蜂巢芯层材料对粉末的电性吸引，粉末可以按预定的量简单的快速地涂敷到蜂巢芯层材料上。
在此情况下，在施涂粉末之前，将纸质蜂巢状芯层材料用水润湿是有益的，因为这可以使得向纸质蜂巢状芯层材料施加合适电荷更加容易。
润湿优选采用水喷雾法进行，水的用量优选是使获得的湿度等于蜂巢状纸重的15-30％。通过喷雾，使纸迅速且容易地获得一种均匀的、适当的湿度。现已确定所述的湿度在实践中达到了良好效果。
对于聚合物粉末而言，优选热固性聚酯或环氧化合物。因为由热固性聚酯或环氧化合物或者两者的混合物可以制成一种强防潮和防水涂层。
当热固性粉末被施涂之后，用一种有利的方法加热蜂巢状芯层材料，以便使粉末变成一层坚硬的厚涂层，并使涂覆后的蜂巢状芯层材料稳定在膨胀状态，其中优选采用热空气或红外辐射的方法加热，以获得快速而均匀的加热效果。
本发明还涉及使用上述方法获得的纸质蜂巢状芯层材料。
