In the process of oil exploitation, an oil-water well oil pipe, a casing and an underground tool are of great importance as a bridge for connecting oil exploitation, the consumption of the bridge is large, the requirement on safety and stability is high, and the bridge is used for a long time when going down a well once and is a key part for stabilizing and producing high yield of an oil field for a long time. The actual situation on site shows that after the oil-water well is put into operation, the corrosion environment suffered by the pipeline is gradually worsened, the pipeline damage is gradually serious, and the pipeline becomes a great problem which restricts the great development of oil fields and improves the development benefit. In the middle and later period of development of oil fields, with the rising of water content of oil wells and the increase of directional wells of inclined wells, the problems of eccentric wear and abrasion of oil pipes become more and more serious.
With the development of nanotechnology, the inherent corrosion resistance of titanium alloy is fully utilized, and the titanium alloy has excellent corrosion resistance particularly under the conditions of chloride, seawater, oxidizing medium and partial reductive acidic condition. However, the cost of the titanium alloy nanometer is extremely high, and for salt spray corrosion, the titanium alloy has higher equipotential due to titanium metal itself, and the larger the addition amount is, the more easily large cathodes and small anodes are formed at the scratch positions, so that the salt spray performance is poorer. On the other hand, the nano titanium dioxide has the characteristics of high density, strong refractive index and low price, and can be used for replacing titanium alloy nano products.
At present, the field of nano titanium dioxide paint preparation is not perfect, the problems of crosslinking and dispersion are easy to occur, and the dispersion rate and the crosslinking degree of a nano material can greatly influence the coating performance of a paint product. Therefore, how to prepare the nano anticorrosive coating based on the nano slurry, improve the quality of the anticorrosive coatings on the inner and outer walls of the pipeline and provide a product with high cost performance is a problem to be solved urgently.

The silicon hydroxyl of the epoxy silane coupling agent on the nano rare earth and the nano titanium dioxide and the phenolic hydroxyl of the epoxy modified phenolic resin are crosslinked to form high-activity dangling bonds in rare earth modified nano titanium dioxide particles, which is beneficial to crosslinking with organic polymer resin.
