摘要
近几十年来,中国石油产业飞速发展,生产生活的各个领域对于石油的需求量也呈现出逐年上升的趋势.在石油采集、输送、贮存以及工业化加工的一系列过程中,石油油罐始终都作为其中必不可少的媒介.然而,石油储罐的防腐问题始终存在,既要保障石油在输送过程中的质量,又要提高储油罐的防腐性能以及使用寿命,这成为当前所有相关研究人员应关注的重点.基于此,在造成石油储罐腐蚀的因素基础上对防腐涂层进行优化设计,将石墨烯添加到双组份水性环氧树脂中,制备石墨烯-环氧树脂复合涂层,研究复合涂层在模拟海水溶液中的隔水和防腐性能.在环氧树脂中加入0.5％(质量分数)的石墨烯后,其低频阻抗模值相比于未添加石墨烯的纯环氧涂层提升了两个数量级,自腐蚀电流密度也降低了一个数量级,涂层的耐蚀性能增强.
Abstract
In recent decades,China's oil industry has developed rapidly,and the demand for oil in various fields of production and life has also shown an increasing trend year by year.In a series of processes of oil collection,trans-portation,storage and industrial processing,oil tanks have always been an indispensable medium.However,the problem of anti-corrosion of oil storage tanks always exists,which should not only ensure the quality of oil in the transportation process,but also improve the anti-corrosion performance and service life of oil storage tanks,which has become the focus of all relevant researchers.Based on this,in this paper,the anti-corrosion coating was opti-mized on the basis of the factors causing the corrosion of oil storage tanks,and graphene was added to the two-com-ponent waterborne epoxy resin with graphene as the filler to prepare the graphene-waterborne epoxy composite coat-ing,and the water insulation and anti-corrosion properties of the composite coating in the simulated seawater solu-tion were studied.After adding 0.5％graphene to the epoxy resin,the low-frequency impedance modulus is in-creased by two orders of magnitude compared with the pure epoxy coating without graphene,and the self-corrosion current density is also reduced by an order of magnitude,and the corrosion resistance of the coating is enhanced.
