摘　　要：针对目前厚浆型环氧树脂与厚浆环氧(HS)固化剂搭配使用的涂层室温实干时间过长(>6 h),不满足高固含压载舱涂料的室温实干时间(≤4 h)问题,采用了苯酚、多聚甲醛、硫脲、三乙烯四胺作为原料合成制备出一种酚醛胺加成固化剂,研究了其与HS固化剂按照质量比1∶0.5、1∶1、1∶2、1∶3、1∶4复配的涂层性能。结果表明,与HS固化剂1∶4质量比复配的涂层性能最佳,不仅可以缩短涂层室温实干时间至3.5 h,而且涂层还具有优异的力学性能和耐候性能,满足目前高固含压载舱涂料的性能需求。Aiming at the problem that the room temperature drying time of the coating used with thick slurry epoxy resin and matching the thick-paste epoxy(HS)curing agent was too long(>6 h),which does not meet the room temperature drying time of the high solid content ballast tank coating(≤4 h),phenol,paraformaldehyde,thiourea and triethylene tetramine were used as raw materials to synthesize and prepare a phenolic amine addition curing agent.The properties of the composite coating with phenolic amine addition curing agent and HS curing agent at the mass ratios of 1∶0.5,1∶1,1∶2,1∶3 and 1∶4 were studied.The results showed that the composite coating with phenolic amine addition curing agent and HS curing agent at a mass ratio of 1∶4 had the best performance.It could not only shorten the drying time of the coating to 3.5 h at room temperature,but also had excellent mechanical properties and weather resistance,which could meet the performance requirements of the current high solid content ballast tank coating.
