| 目的 研究重防腐涂料环氧玻璃鳞片耐蚀耐磨性能。 方法 对环氧玻璃鳞片与其它 3 种环氧类涂层进行磨耗实验,通过紫外线老化、低温暴露和盐雾等系列力学和耐腐蚀性能检测,研究环氧玻璃鳞片的耐腐蚀性能。 结果 各涂层都符合磨损性能指标(1000 转的磨耗量小于 1. 8 g),环氧玻璃鳞片的耐磨性比环氧树脂涂层较差,但是比另外两种环氧类涂层耐磨性都好;耐蚀循环 2400 h 后,4 种不同环氧类涂层表面均出现粉化、锈点,变色明显;环氧玻璃鳞片的结合力好于其他 3 种达到 6. 7 MPa,并且划线处的起泡数目最少,单边扩蚀只有 2. 5 mm,失光率最小。 结论 环氧玻璃鳞片涂层中由于鳞片的层状分布,延缓了腐蚀介质的渗透,具有良好的耐磨耐蚀性能,可以作为一种高效的重防腐涂料,应用于海洋、船舶等环境中。 |

| Objective To study the corrosion and wear resistance of epoxy glass flakes. Methods Epoxy glass flakes and the other three kinds of epoxy coatings were analyzed by abrasion experiment, ultraviolet aging test, low temperature exposure test and salt spray test and a series of mechanical and corrosion resistance tests to explore the corrosion resistance property of the epoxy glass flakes. Results All the coatings accorded with wear performance index (quality changes after abrasion 1000 r less than 1. 8 g), the abrasion resistance of epoxy glass flakes was inferior compared to epoxy resin coating, but higher than the other two kinds of epoxy coatings. After the cycle test of corrosion for 2400 h later, pulverization, rust and obvious color changes appeared on the surface of all coatings. The adhesion strength of the epoxy glass flake still reached 6. 7 MPa which was better than the other three, and the epoxy glass had the least number of foaming lines with the unilateral corrosion of only 2. 5 mm and the minimal light loss rate. Conclusion Due to the layer distribution of flakes, the epoxy glass flake coating delays the penetration of corrosive medium and has good wear-resisting corrosion resistance, which can be used as an efficient heavy-duty coating for application in the marine and navigating environment. |
