摘 要:开发了一种深水装备用无溶剂酚醛环氧涂料,探讨了不同官能度的酚醛环氧树脂用量、
固化剂类型、偶联剂用量、云 氧化铁用量等因素对涂层硬度、耐磨性、干/湿附着力、耐高压性、耐海
水浸泡性能、耐阴极剥离性和抗氯离子渗透性等性能的影响。结果表明:以官能度2. 8的酚醛环氧树
脂 DEN431与官能度 2. 35的酚醛环氧树脂 EPALLOY8240按照质量比 3∶1复配作为主体树脂,添加占
A组分树脂质量 1%的偶联剂 GX-560和 A组分质量 20%的云 氧化铁,改性脂环胺 B为固化剂,开发
的无溶剂酚醛环氧涂料性能满足 NORSOK M-501:2022 对应用于浸没环境涂层的技术要求,通过南
海12个月1 000 m深水原位试验,表明其具备优异的深水环境长效防腐性能。

Abstract:This research developed a solvent-free phenolic epoxy coating for deepwater
equipment. The effects of the content and proportion of three kinds of phenolic epoxy resin
t
with different functionalities,he type of curing agent,he content of coupling agent,and the
t
content of mica iron oxide on the film hardness,abrasion resistance,dry/wet adhesion,high
pressure resistance,seawater immersion resistance,cathodic disbondment resistance,and
chloride ion penetration resistance were investigated. The results showed that the solvent-free
phenolic epoxy coating developed with m(DEN431)∶m(EPALLOY8240)=3∶1 as the main
resin,1% coupling agent GX-560 by the mass of component A resin,20% mica iron oxide by
mass of component A,nd modified cyclic amine B as the curing agent. The performance of the
a
developed solvent-free phenolic epoxy coating was satisfied with the technical requirements of
NORSOK M-501:2022 for coatings applied in immersion environments. The results of 12-
