利用特种环氧自催化反应和迈克尔加成放热反应,制得可低温固化的环氧防腐涂料。对比测试低温固化环氧和普通环氧固化涂料在不同温度下的T_(g),对比计算出低温固化环氧在不同温度下的固化程度都高于普通常温固化环氧。通过测试低温固化环氧在各个温度下的干燥速度和防腐性能,得出此低温固化涂料不仅低温固化速度快,而且防腐性能好。最后分析了不同颜基比、溶剂、固化促进剂以及不同硅烷偶联剂的使用对涂料施工性能、干燥性能和防腐性能的影响。

Low temperature curable epoxy anticorrosive coatings were prepared by special epoxy autocatalytic reaction and Michael addition exothermic reaction.The T_(g)of low temperature curing epoxy and ordinary epoxy curing coatings at different temperatures were contrast tested.,through the comparative calculations,The curing degree of low temperature curing epoxy at different temperatures is higher than that of ordinary room temperature curing epoxy.After testing the dry speed and anti-corrosive property of low temperature curing epoxy coating,get the result that this products not only has property of fast dry speed in low temperature but also has good anti-corrosive property.Finally,the effects of different PVC solvents,curing accelerators and different silane coupling agents on the application performance,drying performance and anti-corrosion performance of the coating were analyzed.
