Abstract

The paper presents the results of experimental studies aimed at improving the operational and repair characteristics of water transport surfaces by developing and implementing new polymer coatings with improved anti-corrosion characteristics. The main purpose of the study is to establish the patterns of the influence of heterogeneously dispersed fillers on the corrosion resistance of epoxy composite coatings. The epoxy oligomer ED-20, polymerized with polyethylenepolyamine (PEPA), was used as a matrix for protective coatings. To modify the polymer structure, a filler system was used, which includes a nanodispersed fullerene-carbon black mixture (30–40 nm) and microdispersed trimethoprim (5–10 μm). Optimization of the composition was carried out using the method of mathematical planning of experiments in the STATGRAPHICS® Centurion XVI software environment. Corrosion resistance was studied using impedance spectroscopy, which determined the electrical resistivity and capacitance of the coatings in three model aggressive media: a 10% sulfuric acid solution, acetone, and seawater (35‰). It was found that the introduction of trimethoprim contributes to additional chemical crosslinking of the polymer matrix, while the nanodispersed filler forms the effect of a “labyrinth structure”, reducing the diffusion permeability of the coating. It was experimentally confirmed that the developed compositions increase resistivity (0.25–0.29 Ω·m²) and decrease capacitance (16–27 pF/m²), indicating the formation of a dense, hydrophobic, and structurally stable polymer network. The maximum values of the studied parameters are characterized by the EС-3 coating, which exceeds the performance of the base matrix by 56% and HEMPEL, HEMPALIN ENAMEL coatings by 24–28%. A generalized model of the mechanism underlying increased corrosion resistance is proposed, based on three key processes: chemical crosslinking, nanomodification, and hydrophobicization of the polymer structure.
