Description

一种抗菌铝单板的表面处理方法
技术领域
本发明涉及铝单板表面处理技术领域，尤其涉及一种抗菌铝单板的表面处理方法。
背景技术
铝单板是指经过铬化等处理后，再采用氟碳喷涂技术，加工形成的建筑装饰材料。氟碳涂料主要是指聚偏氟乙烯树脂，分抗菌粉末层、抗腐蚀层、清漆三种，喷涂过程一般分为二涂、三涂或四涂。氟碳涂层具有卓越的抗腐蚀性和耐候性，能抗酸雨、盐雾和各种空气污染物。
目前，现有的铝单板的表面处理方法仍存在一些不足之处，其一，现有的铝单板的表面处理方法中铝单板的钝化程度较差，且表面容易有异物附着，使得铝单板平整度较差；其二，现有的涂层中的漆料粘度较差，且耐冷热性能较差，使得漆面在长期温差变化中容易出现断裂甚至脱落；其三，现有的漆料多采用单一的氟碳材料，抗紫外线能力较差，铝单板在经长时间紫外线照射下，容易出现自然褪色，进而出现明显的色差，影响铝单板的使用效果。
但是，氟碳漆喷涂并不满足环保要求，因此急需一种可以免除氟碳漆喷涂的抗菌铝单板的表面处理方法。
发明内容
本发明的目的是为了解决上述问题，而提出的一种抗菌铝单板的表面处理方法。
为了实现上述目的，本发明采用了如下技术方案：
一种抗菌铝单板的表面处理方法，其特征在于，包括以下步骤：
步骤一：将铝单板放入浸泡槽中，加入质量分数为25％的混合液，恒温加热至40摄氏度，进行超声波清洗；
步骤二：取出铝单板，经无纺布擦拭后，放入钝化液中浸泡1-2分钟；
步骤三：将聚氨酯酰胺热熔颗粒投放至在乙醇中，40摄氏度加热2-3分钟，生成10-40wt％的稀释液后，投放纳米水滑石，充分搅拌制成胶黏剂；
步骤四：将二苯甲酮与苯并三氮唑按照1:1质量比进行混合，经搅拌后生成紫外线吸收剂；
步骤五：将胶黏剂、紫外线吸收剂与抗菌涂料按照1：1:3的质量比进行混合，得到新型复合抗菌组合物；
步骤六：将步骤二中的铝单板取出，经清水冲洗3-5分钟之后取出烘干，在通过高压静电喷枪将步骤五中的新型复合抗菌组合物分两次均匀覆盖在铝单板外表壁，进而在铝单板外表壁生成复合抗菌粉末层、抗腐蚀层，待固化后，即可完成抗菌铝单板的表面处理。
作为上述技术方案的进一步描述：
所述混合液由丙酮与盐酸按照2：1质量比组成。
作为上述技术方案的进一步描述：
所述钝化液由氢氟酸2份、硫酸铝钾2份、高锰酸钾3份、叔丁醇2份与钛酸钾1份组成。
作为上述技术方案的进一步描述：
所述步骤四中还添加有淬灭剂。
作为上述技术方案的进一步描述：
所述步骤五中的抗菌涂料为Ag2SO4、Ag2O2按照重量比1:3配比的复合抗菌涂料。
作为上述技术方案的进一步描述：
所述步骤六中的复合抗菌粉末层喷洒厚度为5-10微米，抗腐蚀层喷洒厚度为23-30微米。
综上所述，由于采用了上述技术方案，本发明的有益效果是：
1、本发明中，丙酮在盐酸的催化下会生成双丙酮醇，双丙酮醇会降低异物的粘性，配合上超声波震动，使得铝单板外表壁附着的异物快速脱离，而有多种溶液组成的钝化液能够与清洗过后的铝单板表面反应，进而生成强度较大的致密氧化膜，从而提高了铝单板的钝化程度的同时保证了其表面的平整度。
2、本发明中，聚酯酰胺热熔胶与纳米水滑石在碱性的环境下生成的胶黏剂，按比例混合进抗菌涂料之后，使得抗菌涂料具有较高的粘结性，进而在温差变化中具有抗剥离强度与柔韧性，使得铝单板在长时间暴露在外部环境时，其抗菌涂料不易发生软化或断裂，热稳定性良好。
3、本发明中，由二苯甲酮与苯并三氮唑混合制成的紫外线吸收剂，混合到抗菌涂料中后，协同淬灭剂进行紫外线的吸收，进而提高铝单板外表壁抗菌涂料的抗紫外线性能，降低了铝单板在使用过程中抗菌涂料出现褪色的速率，从而提高了铝单板的使用效果。
