Description
技术领域
本发明属于精细化工领域,涉及一种高效环保水基清洗剂,特别涉及一种飞机表面低红外发射涂层用水基清洗剂。
背景技术
飞机在高空飞行和地面停放期间,其外表面蒙皮易沉积盐、灰尘、油污等污染物,这不仅会影响飞机的整体外观,使其表面不美观光洁度降低,摩擦阻力增大,更为严重的是这些地方往往成为腐蚀的诱发因素,引发或者加速腐蚀。
对于飞机表面的低红外发射涂层,其表面的污染物会严重影响其性能。随着红外探测技术的飞速发展,对飞机红外隐身技术的研究己得到世界各国的高度重视,其中低发射率红外隐身涂料是当今红外隐身技术中较为活跃的研究领域。低红外发射涂层顾名思义,其最大的性能就是发射率低,在低红外发射涂层表面粘上污垢后,会大大影响其低红外发射的性能,发射率变大。由于涂层的特殊性,不能使用有机溶剂类的清洗剂,因为有机溶剂会使涂料脱落,影响其低发射性能。
在常温下,水的表面张力为72.3mN/m,对油污的润湿性很差,只有在水中加入表面活性剂后,才能有较好的润湿性。当表面活性剂水溶液表面张力低于物体及油污的润湿临界张力后才能在其表面铺展开。当洗涤液比油更易润湿物体时,才会使原来铺展的油膜逐渐卷缩成油珠,再在机械外力的作用下就很容易离开物体。使用市场上广泛使用的安利系列的水基清洗剂清洗飞机表面的低红外发射涂层上的油污,其清洗效果不佳,对于涂层的低发射性能有所影响,发射率会增加,没有达到理想的效果。鉴于目前市面上还没有飞机表面低红外发射涂层专用的清洗剂,所以就需要研发出一种高效的水基清洗剂,既 不影响其低红外发射的性质又能将其表面清洗干净。
发明内容
针对上述存在问题或不足,本发明提供了一种飞机表面低红外发射涂层用水基清洗剂及其制备方法,在不影响涂层低红外发射的性质下又能将其表面高效的清洗干净。
该飞机表面低红外发射涂层用水基清洗剂按重量百分数配比如下:表面活性剂5%-6%脂肪醇聚氧乙烯醚AEO-9,6%-8%脂肪酸甲酯乙氧基化物磺酸钠FMES,2.5%-3%直链烷基苯磺酸钠LAS,和4.5%-5%辛烷基苯酚-10OP-10;复合缓蚀剂5%-6%,其他助剂1.5%-2%,70%-75.5%去离子水溶剂。
所述复合缓蚀剂为4.5%-5.5%硅酸钠和0.3%-0.5%苯并三氮唑。
所述其他助剂为0.2%-0.5%焦磷酸钠和1%-1.5%硅油消泡剂。
其配置过程如下:
步骤1、按重量百分数称取表面活性剂:5%-6%脂肪醇聚氧乙烯醚AEO-9,6%-8%脂肪酸甲酯乙氧基化物磺酸钠FMES,2.5%-3%直链烷基苯磺酸钠LAS,和4.5%-5%辛烷基苯酚-10OP-10;复合缓蚀剂:4.5%-5.5%硅酸钠和0.3%-0.5%苯并三氮唑;其他助剂:0.2%-0.5%焦磷酸钠和1%-1.5%硅油消泡剂,70%-75.5%去离子水溶剂;
步骤2、将步骤1中称取的四种表面活性剂加入到烧杯中,搅拌混合均匀;
步骤3、将步骤1中称取的复合缓蚀剂和其它助剂加入到上述步骤2所得溶液中,然后边搅拌边加入步骤1中称取的去离子水至所有成分全部溶解,搅拌均匀,即配制成飞机表面低红外发射涂层用水基清洗剂。
上述清洗剂的使用方法:按清洗剂:去离子水1:2-1:15稀释,然后均匀喷洒或涂刷在低发射红外涂层的待洗部位,保持30s-60s,来回擦拭5-10次,再用去 离子水清洗干净。
本发明的有益效果是:在不影响涂层低红外发射的性质下又能将其表面高效的清洗干净,其清洗效果优于市面上的水基清洗剂,稳定性高使用简单。
具体实施方式
按照重量配比依次称取表面活性剂,复合缓蚀剂,其他助剂;
制备方法如下:
步骤1、称量:按照质量分数称取表面活性剂脂肪醇聚氧乙烯醚AEO-9 6g,占清洗剂质量的6%,脂肪酸甲酯乙氧基化物磺酸钠FMES 8g,占清洗剂质量的8%,直链烷基苯磺酸钠LAS 3g,占清洗剂质量的3%,和辛烷基苯酚-10OP-10 5g,占清洗剂质量的5%;复合缓蚀剂6g,占清洗剂质量的6%,其他助剂2g,占清洗剂质量的2%,溶剂去离子水70g,占清洗剂质量的70%。所述复合缓蚀剂为硅酸钠5.5g,占清洗剂质量的5.5%和苯并三氮唑0.5g,占清洗剂质量的0.5%,所述其他助剂为焦磷酸钠0.5g,占清洗剂质量的0.5%和硅油消泡剂1.5g,占清洗剂质量的1.5%。
步骤2、将步骤1中称取的四种表面活性剂加入到一洁净的烧杯中,搅拌混合均匀。
步骤3、将步骤1中称取的复合缓蚀剂和其它助剂加入到上述步骤2所得溶液中,然后边搅拌边加入步骤1中称取的去离子水至所有成分全部溶解,搅拌均匀,即配制成100g飞机表面低红外发射涂层用水基清洗剂。
在0℃~60℃进行升温降温5次重复试验,清洗剂溶液无沉淀,分层等现象出现,均能保持清洗剂的稳定。
将配制的清洗剂按清洗剂:去离子水1:15稀释,然后均匀喷洒或涂刷在低发 射红外涂层的待洗部位,保持40s,用海绵刷来回擦拭5次,再用去离子水清洗干净,清洗效果明显,在稀释比例为1:15,清洗效率还能达到93%。在该稀释浓度范围下对低红外发射涂层发射率的影响如下表1:
在该稀释浓度范围下对低红外发射涂层Lab值的影响如下表2:
