| Abstract: |
| 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. |
