Functional Polymer Nanocomposites with Increased Anticorrosion Properties and Wear Resistance for Water Transport

Corrosive destruction and hydroabrasive wear is a serious problem in the operation of machine parts water transport mechanisms. It promising to develop new composite materials with improved properties increase reliability vehicles. In this regard, use polymer-based materials, which are characterized by anticorrosion resistance, promising. work, therefore, for formation multifunctional protective coatings, epoxy dian oligomer brand ED-20, polyethylene polyamine (PEPA) hardener, mixture nanodispersed compounds dispersion 30–90 nm, fillers Agocel S-2000 Waltrop 8–12 μm, particles iron slag 60–63 μm used coatings. Using method mathematically planning experiment, content additives different physico-chemical natures binder optimized obtain fireproof coatings operational characteristics. A mathematical model developed optimizing components wear-resistant means as result complex effect compounds, scale, Waltrop. Based on regularities increasing corrosion resistance resources established through four tested aggressive environments (technical water—CAS No. 7732-18-5, gasoline—CAS 64742-82-1, acetone—CAS 67-64-1, I-20A lubricant—CAS 64742-62-7, sodium solutions—CAS 1310-73-2, sulfuric acid—CAS 7664-93-9) resistances. study change permeability index additionally carried out, taking into account rational ratio dispersive binder, made it possible create an effective barrier penetration molecules base. decrease 2.0–3.3 times relative matrix achieved. addition, under action hydroabrasion investigated. The CM was found testing gas-abrasive centrifugal accelerator. This enables one real process mechanism action. shown that coefficient 1.3 higher than polymer matrix, indicates composites influence environment. As result, modified conditions developed. coating filled (30–90 nm), scale (60–63 μm), (8–12 μm) has lowest indicators. natural such during time t = 300 days χ 0.5%, 3.6 less similar indicators matrix. substantiated highest resistance.
