Abstract Faced with severe corrosion of casing in oil wells, the epoxy coating was applied to prevent corrosion. Based on the mechanism that the filler eliminated the internal stress during the curing process of the coating and prevented the penetration of corrosive medium into the coating, a new filler was successfully prepared by the hydrothermal method. When the molar ratio of the precursor of ZrO2 to MoS2 was 1.2:1, MoS2 was uniformly modified with ZrO2 through mussel inspired chemistry of dopamine. Introducing fillers into epoxy coatings, specifically, a proper content of 0.8 wt.% filler can greatly improve the mechanical properties and corrosion resistance of the coatings. The coating maintained the excellent corrosion resistance for 16 h under high temperature (108 °C) and high pressure (pressurized with CO2 gas of 35 MPa), which would provide us a reliable anticorrosive coating for oil wells metal casing.

MoS2通过多巴胺的贻贝启发化学修饰用ZrO2纳米粒子增强环氧涂层的防腐

摘要 面对油井套管的严重腐蚀，采用环氧涂层进行防腐。基于填料在涂层固化过程中消除内应力、防止腐蚀介质渗入涂层的机理，采用水热法成功制备了一种新型填料。当 ZrO2 的前体与 MoS2 的摩尔比为 1.2:1 时，MoS2 被 ZrO2 通过贻贝激发的多巴胺化学均匀修饰。在环氧涂料中加入填料，特别是0.8wt.%的填料含量可以大大提高涂料的力学性能和耐腐蚀性能。该涂层在高温（108℃）和高压（用35MPa的CO2气体加压）下保持16小时的优异耐腐蚀性能，
