内容摘要

  近年来,水性防腐涂料研究及开发已经成为涂料行业的热点。但是,水性防腐涂料产品的性能还赶不上溶剂型工业涂料,这是由目前水性涂料的自身配方决定的。为了解决这一难题,我们制备了一系列石墨烯增强的水性聚氨酯、水性环氧复合涂层。利用石墨烯的高径厚比特性,通过表面化学状态调控,改善了石墨烯与涂层基质的相容性,提高了石墨烯和涂层的界面相互作用,充分发挥了石墨烯的阻隔屏障性能。首先,在水性聚氨酯分散体中,我们加入了聚碳化二亚胺改性的石墨烯,该功能化的石墨烯在涂料中表现出非常好的抗沉降性能。在中性盐雾(NSS)测试中,延长出现相同腐蚀面积的时间60-70%。在电化学阻抗谱(EIS)的测试中,相比于纯涂层,加了改性石墨烯的复合涂层损坏时间提升至17倍以上。然后,在水性环氧涂层体系中,我们引入了磺化石墨烯,从扫描电子显微镜(SEM)/透射电子显微镜(TEM)表征结果来看,磺化石墨烯在涂层中有着良好的分散性,随着含量提高,石墨烯在涂层中出现了有序排列。从32天的NSS测试结果看,纯环氧涂层表面出现了明显的腐蚀,而含1%石墨烯的复合涂层几乎无变化。同时发现,大尺寸的石墨烯对涂层的耐腐蚀性能有更大提高。另外,我们还研究了在环氧涂料里具有帮助固化的聚醚胺改性石墨烯。EIS结果来看,0.2%添加量对涂层的耐蚀增强作用最明显,NSS测试也呈现相同的规律,可能跟石墨烯的分散状态有关。耐候性测试结果表明,加入石墨烯含量最高(0.5%)的涂层抵御紫外线(UV)的效果最好,经历60d的UV曝晒后涂层的形貌和硬度都几乎没有变化。
