石墨烯防腐构件性能试验研究

Experimental Study on the Performance of Graphene Anti-Corrosion Components

针对常用镀锌公路护栏抗腐蚀性能一般、易变色且其镀锌工艺易影响防腐效果等问题,提出将石墨烯纳米复合防腐涂料用于公路护栏防腐。通过对传统镀锌、镀锌喷塑防腐涂层和石墨烯纳米复合防腐涂层做对比试验,并分别进行抗腐蚀、耐紫外线和机械性能试验。结果表明石墨烯纳米复合防腐试件抗腐蚀性能和机械性能均明显优于镀锌试件和镀锌喷塑试件,三者抗紫外老化性能几乎一致。由此得出石墨烯纳米复合防腐涂料满足工程使用要求并优于镀锌及镀锌喷塑防腐。

In response to the problems of general corrosion resistance,easy color change,and the impact of galvanizing process on the anti-corrosion effect of commonly used galvanized highway guardrails,it is proposed to use graphene nanocomposite anti-corrosion coatings for highway guardrail anti-corrosion.By comparing traditional galvanizing,galvanizing spray coating,and graphene nanocomposite anti-corrosion coating,tests of corrosion resistance,UV resistance,and mechanical performance are conducted respectively.The results show that the corrosion resistance and mechanical properties of graphene nanocomposite anti-corrosion specimens are obviously better than those of galvanized specimens and galvanized spray coated specimens,and the UV aging resistance of the three specimens is almost the same.Thus it can be seen that the graphene nanocomposite anti-corrosion coating meets the requirements of engineering use and is superior to galvanized and galvanized spray coating anti-corrosion.
