摘　　要：针对船闸钢结构防腐重涂修复难、影响船闸检修工期等问题,深入分析船闸钢结构腐蚀的机理和需求,全面了解行业前沿的技术、材料和工艺,详细介绍石墨烯锌粉涂料在船闸钢结构防腐中的应用。通过案例运用、比较分析,从多方面对石墨烯锌粉涂料和传统防腐体系进行对比,得出石墨烯锌粉涂料较环氧富锌涂料性能有较大提高;石墨烯锌粉涂料与热喷锌防腐性能相当,但更加便捷、环保。通过典型防腐方案的全寿命经济效益对比得出,石墨烯锌粉涂料环保性好、实施方便、全生命周期成本低,是一种值得推广的船闸钢结构防腐材料。The anti-corrosion recoating and repair of steel structures in ship locks are difficult and influence the maintenance period of the ship locks. In response, this paper deeply analyzes the corrosion mechanism and anti-corrosion demand of steel structures in ship locks and outlines relevant cutting-edge technologies, materials, and processes. In addition, the paper introduces in detail the application of graphene zinc powder coating in the anti-corrosion of steel structures in ship locks. Through case application and comparative analysis, this paper compares the graphene zinc powder coating and a traditional anti-corrosion system in many aspects and concludes that the performance of the graphene zinc powder coating is much better than that of a zinc-rich epoxy coating. Graphene zinc powder coating is comparable to thermal sprayed zinc in anti-corrosion but is more convenient and environmentally friendly. As indicated by the comparison of the life-cycle economic benefits among typical anti-corrosion schemes, the graphene zinc powder coating has good performance in environmental protection, convenient implementation, and low life-cycle cost, becoming an anti-corrosion material worthy of promotion for steel structures of ship locks.
