Description

铝单板仿铜拉丝工艺
技术领域
本发明涉及铝单板表面处理技术领域，具体涉及一种铝单板仿铜拉丝工艺。
背景技术
铝单板具有优异的加工性能，同时具有自身重量轻、价格低、抗压强度高等优点，可广泛应用于建筑装饰领域。近年来随着市场发展的需求以及行业产品档次的提高，人们不仅要求铝单板具有优良的性能，对铝单板的外观美观性的要求也越来越高。
对铝单板采用仿铜拉丝工艺可以获得仿铜拉丝效果。现有的应用于铝单板的仿铜拉丝工艺一般是在铝单板表面喷涂仿铜拉丝漆后采用百洁布等带有纹路的材质进行拉丝打磨，采用上述工艺形成的仿铜拉丝过于粗糙，美观程度差，而且漆面的稳定性较差，容易脱落或腐蚀。
发明内容
为了克服现有技术的不足，本发明提供了一种稳定性好，耐久性、耐腐蚀性高的铝单板仿铜拉丝工艺。
本发明采用如下技术方案实现：铝单板仿铜拉丝工艺，包括如下步骤：
S1、对铝单板进行前处理，实现除锈、除油，并干燥；
S2、将铝单板置于铬酸盐溶液中，在85-90℃的温度下浸渍2-3min，在铝单板表面生成铬化层；
S3、在步骤S2中所述的铬化层上喷涂第一氟碳漆层，然后在第一氟碳漆层上覆盖网格布、并喷涂第二氟碳漆层，所述第一氟碳漆层的含氟量为70％-75％，所述第二氟碳漆层的含氟量为76％-80％；
S4、在步骤S3中所述的第二氟碳漆层上喷涂铜粉，形成界面层；
S5、在步骤S3中所述的界面层上喷涂仿铜面漆，再使用表面具有拉丝纹路的辊筒滚压产生拉丝效果；
S6、在步骤S5中带有拉丝效果的仿铜面漆上喷涂罩光面漆，烘干，完毕。
所述第一氟碳漆层喷涂完毕后，置于自然条件下，表面凝固后，覆盖网格布，在所述第二氟碳漆层喷涂完毕后，放入烘箱，在200℃的温度下烘烤20min。
步骤S4中所述铜粉粒径为1-1.5μm。
步骤S5中所述辊筒压设在仿铜面漆上，所述辊筒的转动速度为0.5-0.6m/s。
在产生拉丝效果后，使用风机吹除表面杂质，在无尘环境下喷涂罩光漆。
相比现有技术，本发明通过对第一氟碳漆层及第二氟碳漆层内的含氟量的调整，能可靠提高铝单板的耐腐蚀性，通过网格布的连接作用，可靠提高第一氟碳漆层及第二氟碳漆层的牢固性，进而有效提高仿铜面漆的耐久性。
具体实施方式
下面，结合具体实施方式，对本发明做进一步描述，需要说明的是，在不相冲突的前提下，以下描述的各实施例之间或各技术特征之间可以任意组合形成新的实施例。
实施例一
铝单板仿铜拉丝工艺，包括如下步骤：
S1、对铝单板进行前处理，实现除锈、除油，并干燥；
S2、将铝单板置于铬酸盐溶液中，在85-90℃的温度下浸渍2-3min，在铝单板表面生成铬化层；
S3、在步骤S2中所述的铬化层上喷涂第一氟碳漆层，然后在第一氟碳漆层上覆盖网格布、并喷涂第二氟碳漆层，所述第一氟碳漆层的含氟量为70％，所述第二氟碳漆层的含氟量为76％；
S4、在步骤S3中所述的第二氟碳漆层上喷涂铜粉，形成界面层；
S5、在步骤S3中所述的界面层上喷涂仿铜面漆，再使用表面具有拉丝纹路的辊筒滚压产生拉丝效果；
S6、在步骤S5中带有拉丝效果的仿铜面漆上喷涂罩光面漆，烘干，完毕。
实施例二
铝单板仿铜拉丝工艺，包括如下步骤：
S1、对铝单板进行前处理，实现除锈、除油，并干燥；
S2、将铝单板置于铬酸盐溶液中，在85-90℃的温度下浸渍2-3min，在铝单板表面生成铬化层；
S3、在步骤S2中所述的铬化层上喷涂第一氟碳漆层，然后在第一氟碳漆层上覆盖网格布、并喷涂第二氟碳漆层，所述第一氟碳漆层的含氟量为72％，所述第二氟碳漆层的含氟量为78％；
S4、在步骤S3中所述的第二氟碳漆层上喷涂铜粉，形成界面层；
S5、在步骤S3中所述的界面层上喷涂仿铜面漆，再使用表面具有拉丝纹路的辊筒滚压产生拉丝效果；
S6、在步骤S5中带有拉丝效果的仿铜面漆上喷涂罩光面漆，烘干，完毕。
实施例三
铝单板仿铜拉丝工艺，包括如下步骤：
S1、对铝单板进行前处理，实现除锈、除油，并干燥；
S2、将铝单板置于铬酸盐溶液中，在85-90℃的温度下浸渍2-3min，在铝单板表面生成铬化层；
S3、在步骤S2中所述的铬化层上喷涂第一氟碳漆层，然后在第一氟碳漆层上覆盖网格布、并喷涂第二氟碳漆层，所述第一氟碳漆层的含氟量为75％，所述第二氟碳漆层的含氟量为80％；
S4、在步骤S3中所述的第二氟碳漆层上喷涂铜粉，形成界面层；
S5、在步骤S3中所述的界面层上喷涂仿铜面漆，再使用表面具有拉丝纹路的辊筒滚压产生拉丝效果；
S6、在步骤S5中带有拉丝效果的仿铜面漆上喷涂罩光面漆，烘干，完毕。
在上述三个实施例中，所述第一氟碳漆层喷涂完毕后，置于自然条件下，表面凝固后，覆盖网格布，在所述第二氟碳漆层喷涂完毕后，放入烘箱，在200℃的温度下烘烤20min。
步骤S4中所述铜粉粒径为1-1.5μm。
步骤S5中所述辊筒压设在仿铜面漆上，所述辊筒的转动速度为0.5-0.6m/s。转动速度过快，容易造成拉丝的丝线断裂，转动速度过慢，降低生产效率。
在产生拉丝效果后，使用风机吹除表面杂质，在无尘环境下喷涂罩光漆。这样，可以防止灰尘、涂料粉末等杂物粘附在仿铜面漆上，使得喷涂罩光漆后杂质被封盖，影响整体的美观性。
对上述三个实施例制作的带有仿铜拉丝效果的铝单板进行盐酸腐蚀测试、自然条件放置测试及外观评测如下表所示：
测试项目 耐盐酸腐蚀 耐久性 外观
实施例一 无变化 好 拉丝美观
实施例二 无变化 好 拉丝美观
实施例三 无变化 好 拉丝美观
由上表可以看出，通过对第一氟碳漆层及第二氟碳漆层内的含氟量的调整，能可靠提高铝单板的耐腐蚀性，通过网格布的连接作用，可靠提高第一氟碳漆层及第二氟碳漆层的牢固性，进而有效提高仿铜面漆的耐久性。
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。
