Description

一种防锈紫外固化涂料
技术领域
本发明涉及涂料领域，尤其是一种防锈紫外固化涂料。
背景技术
UV固化型涂料具有防止污染及节能效果，涂饰的化学性、物理性优秀、有快速固化的特性，正在多个领域被广泛地采纳使用。广泛用于生产塑胶、真空电镀、PVC地板、荫罩板、汽车头灯、木地板、橱柜面板等。UV作为一种新的加工技术在澳大利亚获得商业化已经有25年以上的时间了,而且现在行情继续看好。该项技术正以每年接近10%的速度稳步发展,尤其是在表面涂料和相关工业方面。UV光固化涂料具有不含挥发性有机化合物(VOC)，对环境污染小，固化速度快，节省能源、固化产物性能好、适合于高速自动化生产等优点。而传统涂料易挥发、固化速度慢，不利于环境保护。因此，UV涂料是传统涂料的主要替代品。
钢结构表面防止腐蚀生锈，最简单的方法便是采用涂料保护。油性涂料由于含有大量的有机溶剂，对环境造成极其严重的污染，因此水性防锈漆是各国图了解研究的方向。自从水性防锈漆问世以来，我国水性防锈漆的需求量逐年递增，目前的水性防锈漆在防锈性能、附着力、耐久性、抗裂纹、耐擦洗等方面存在各种不足。
发明内容
针对上诉问题本发明提出一种防锈紫外固化涂料，有着良好的防锈功能及耐久性等。
为了达到上诉目的，本发明采取的技术方案如下。
一种防锈紫外固化涂料其原料按重量份计包括：阴离子丙烯酸树脂55～65份、石墨烯10～15份、肌醇六磷酸酯10～15份、锌粉5～10份、光引发剂3～5份、活性稀释剂7～12份、流平剂0.3～0.6份、防沉剂0.2～0.5份、消泡剂1～1.5份。
所述的涂料原料还含有抗结皮剂、稳定剂、增韧剂等其他助剂。
所述的流平剂为烷基改性有机硅氧烷流平剂、丙烯酸酯流平剂或聚醚改性聚二甲基硅氧烷流平剂。
所述的光引发剂为1-羟基环己基苯基甲酮、2-羟基-2-甲基-1-苯基-1-丙酮、二苯基-(2,4,6-三甲基苯甲酰)氧磷、二苯甲酮、2,4,6-三甲基苯甲酰基苯基膦酸乙酯中的一种或几种。
所述的防沉剂为气相二氧化硅防沉剂或改性聚脲的N一甲基吡咯烷酮防沉剂。
使用本发明具有以下有益效果：
1.采用肌醇六磷酸酯为原料，能在表面与金属迅速螯合，形成一层致密的单分子络合物保护膜，可有效抑制金属的腐蚀，达到良好防锈效果；
2.加入锌粉，具有比金属更低的电极电位，有效的防止电化学腐蚀对金属造成的损失；
3.采用阴离子丙烯酸树脂能与锈层中的活泼有害成分反应，生产稳定的抑制化合物，可以使锈层成为涂料中有效的保护填料；
4.加入石墨使烯涂料的附着力更加牢固，更具有超耐久性，使得涂料耐擦洗，抗裂纹。
