Description

一种表面沉积BN薄膜的氟碳铝单板
技术领域
本发明涉及铝单板技术领域，具体涉及一种表面沉积BN薄膜的氟碳铝单板。
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，分底漆、面漆、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，耐冷热性能极好，能抵御强烈紫外线的照射，能长期保持不褪色、不粉化，使用寿命长。
氟碳铝单板质量轻，刚性好，强度高，耐候性和耐蚀性好，而且工艺性好，涂层均匀、色彩多样，防火性强，使用寿命长。这使得氟碳铝单板在建筑领域倍受青睐，但是铝单板表面的氟碳涂料层表现出强烈的憎水性，表面受到的有机污染物很难被雨水冲洗掉，对于大型桥梁和高楼等建筑的维护十分困难和危险，这不仅耗费大量的人力物力，而且对维护人员来说也是一种潜在的危险。同时现有的氟碳铝单板作为建筑材料时，其防辐射性能依然欠佳，因此研究开发出一种不易受到污染且具有优异防辐射性能的氟碳铝单板意义重大。
发明内容
本发明的目的在于提供一种表面沉积BN薄膜的氟碳铝单板，具有优异的防辐射性能，且BN薄膜抗氧化性能优异、硬度高，有效延长了氟碳铝单板的使用寿命，且BN薄膜表面不易积灰，有机污染物后，易于被水冲刷干净，各层之间结合力强。
为实现以上目的，本发明通过以下技术方案予以实现：
一种表面沉积BN薄膜的氟碳铝单板，包括氟碳铝单板基底、Ni-P化学镀中间层、BN薄膜，所述氟碳铝单板基底表面化学镀Ni-P合金，制得Ni-P化学镀中间层，再采用射频磁控溅射法在Ni-P化学镀中间层表面沉积一层BN薄膜。
优选地，所述化学镀Ni-P合金中所用的Ni-P化学镀液的配方为：硫酸镍25-30g/L、次亚磷酸钠13-18g/L、碳酸钠1-5g/L、环己六醇六磷酸脂10-15g/L、柠檬酸三钠10-14g/L、表面活性剂3-6g/L。
优选地，所述化学镀Ni-P合金中所用的Ni-P化学镀液的配方为：硫酸镍27g/L、次亚磷酸钠17g/L、碳酸钠3g/L、环己六醇六磷酸脂11g/L、柠檬酸三钠13g/L、表面活性剂4g/L。
优选地，所述表面活性剂为十二烷基苯磺酸钠。
优选地，所述氟碳铝单板基底表面化学镀Ni-P合金的工艺包括如下步骤：将氟碳铝单板基底进行脱脂、水洗；将Ni-P化学镀液的pH调整为4-5.5，加热至70-80℃，在该温度下向镀液中加入氟碳铝单板基底，搅拌2-3h；取出氟碳铝单板基底，干燥，在150-170℃下进行热处理7-10h；最后进行水洗、烘干。
优选地，所述BN薄膜厚3-6μm。
本发明的有益效果是：
本发明在氟碳铝单板基底上从内至外依次设置Ni-P化学镀中间层、BN薄膜，其中BN薄膜具有高硬度，因此可对氟碳铝单板基底坚硬的保护膜，从对氟碳铝单板形成很好的保护，同时BN薄膜具有较好的防辐射性能，因此使氟碳铝单板具有优异的防辐射性能，使其在建筑领域得到更广泛的应用，且BN薄膜抗氧化性能优异，因此可明显增强氟碳铝单板的使用寿命。而BN薄膜表面不易积灰，同时在沾染有机污染物后，易于被水/冲刷干净，适用于各种大型桥梁和高楼等建筑中。
在氟碳铝单板基底与BN薄膜之间设置Ni-P化学镀中间层，其中Ni-P化学镀中间层与氟碳铝单板基底之间具有很好的结合力，而Ni-P化学镀中间层与BN薄膜的晶格结构相似，因此两者之间具有很好的结合力，从而使各层之间的结合力大大加强，使制得的氟碳铝单板性能更加稳定。
本发明在化学镀Ni-P合金的过程中，合理配置Ni-P化学镀液的配方，镀钛时呈非晶态的镀层在经过7-10h的150-170℃下低温热处理后，晶相缓慢的不断析出，直至析出完全，同时在缓慢的低热处理过程中，使Ni-P化学镀中间层与氟碳铝单板基底的结合力进一步增强。
