摘要
在国民经济建设中,由钢筋腐蚀引起的资源、能源消耗巨大,相悖于可持续发展的战略目标,因此海洋工程的发展需着重攻克钢筋腐蚀这一难关。随着海洋经济不断发展以及海洋产业结构的调整升级,海洋涂料行业的技术水平不断提高,环氧树脂作为经济效益双收的防腐涂料之一值得深入研究。目前,针对环氧钢筋耐蚀和抑制锈蚀的研究层出不穷,预测环氧钢筋涂层服役性能的理论计算和数值模拟也成为研究热点,但有关可高度适应海洋环境多因素耦合作用下的防护体系仍需深入、系统地开展相关研究。基于此,本文归纳了目前海工钢筋环氧涂层防护性能的评估体系,并从环氧树脂的基体分子结构、改性功能助剂等方面,围绕“阻”“隔”“愈”“缓”四个角度,综述了海工钢筋环氧涂层的多尺度结构设计与防护性能调控研究进展,总结了目前海工钢筋环氧涂层存在的问题,并对其发展前景进行了展望,对未来海工钢筋环氧涂层的超长寿命防护研究具有指导意义。
In the national economic construction,rebar corrosion has caused huge consumption of resources and energy,which is contrary to the strategy of sustainable development.Therefore,the development of marine engineering needs to focus on conquering reinforcement corrosion,which is a very difficult task.With the continuous development of marine economy as well as the adjustment and upgrading of marine industrial structure,the technical level of marine coating industry continues to be improved.Epoxy resin,as one of the anti-corrosion coatings with double economic benefits,is worthy of in-depth study.At present,scientific research on the corrosion resistance and inhibition of epoxy rebar emerge in an endless stream,and it is also hot to predict the service performance of epoxy rebar coating by theoretical calculation and numerical simulation.However,the corrosion-resistant coating still needs to be further developed and explored to adapt to the influence of multiple factors in the marine environment.Based on this,this paper introduces the current evaluation system of the anti-corrosion performance of epoxy reinforcement coating,and summarizes the design and research progress of marine epoxy rebar coating according to the multi-scale structure designs of epoxy resin and the compound coating with multiple protective effects from the perspective of‘resistance’‘isolation’‘healing’and‘inhibiting’.It also puts forward the advantages and disadvantages of various systems,and finally concludes and prospects,which could pose new ideas for the development of marine epoxy reinforcement coating.
