Abstract
In this research work, the optimal conditions of a new type of organic anti-corrosion coating based on methyl methacrylate, monoethanolamine and phosphoric acid and ED-20 epoxy resin were studied. At first, a new compound was synthesized based on methyl methacrylate, monoethanolamine and phosphoric acid, and its structure was studied by YAMR and PMR. The resulting mixture was mixed with ED-20 epoxy resin at different mass percentages of 10, 15, 20, 25 and 35%. The resulting mixture was mixed at a speed of 600 rpm and a temperature of 90 °C for 1,5 hours until a uniform mass was formed in the entire volume. The durability of the resulting coating was tested on a HUATECH scratch tester to assess hardness and scratch resistance. According to the obtained results, the coating thickness is one of the factors affecting the corrosion resistance. It was found that when the thickness of the coating is in the range of 120 μm, the level of stability is better than that of coatings of other thicknesses.
