本文介绍了一种以环氧丙烯酯为主体,添加引发剂、还原剂、促进剂和稳定剂组成的单组分液态厌氧固化型防护材料.它可室温贮存一年以上,将其涂于钢,铜和铝合金之间,可点焊并迅速固化,固化物能经受碱洗(或酸洗)、阳极化和500小时潮热试验.它对焊缝材料基体有良好的保护作用. In this paper, we introduce a one-component liquid anaerobic curing material consisting of propylene oxide as the main component, adding initiator, reducer, accelerator and stabilizer, which can be stored at room temperature for more than one year, Steel, copper and aluminum alloy, spot welding and rapid curing, cured material can withstand alkali washing (or pickling), anodizing and 500 hours hot flashes heat test. It has good protective effect on the weld material matrix.
