Study of Conversion Paint Applicable to Water- and Rust-Containing Working Condition

A conversion paint applicable to water-and rust-containing working condition was successfully developed for the repairing of rusted iron and steel wares. Thus the titled paint was prepared using modified epoxy resin, asphalt, rust-converting agent, complexing agent, anti-rust agent, and solvent as the raw materials. The optimized formulation of the paint was determined. The effects of the major ingredients on the rust-converting capacity and quality of the paint were investigated, and the performance of the paint was examined as well. As the results, the optimal formulation was suggested to be composed of 18% (mass fraction) epoxy resin (E-44), 6% asphalt, 10% solvent (composed of butanol and dimethylbenzene at a volume ratio of 1:1), 35% rust-converting agent, 2% citric acid, 1% sodium di-hydrogen phosphate, 1% sodium molybdate, 1%OP-10, 2% carbon black, 24% ethanol, and 0.5% glycol. The developed paint had high rust-conversion capacity and good performance and could be readily used for the corrosion protection of the facilities made of iron and steel in the presence of water and rust.
