The article describes the effects of surface treatment of concrete protective coatings filled of polimetylfynilsyloksan based on its corrosion resistance. The influence of the coating on the adhesive strength, hydrophobicity and water absorption of concrete. The possibility of using the developed formulations of protective coatings to improve durability of concrete is showed, which is operated under conditions of external aggressive factors.
The thesis is devoted to the development of theoretical bases of the corrosion resistance of concrete by protective coatings on the base of polymethylphenylsiloxane filled with aluminum and zinc oxides. The technological properties of protective coatings compositions were investigated by methods of physical and chemical analysis, methods of the concrete surface coating and form conditions were shown. Determined that the forming matric-oxide structure covering in the process of hardening passpasses behind counting polymerization polymethylphenylsiloxane.
Carboxy derivative of dioxydiphenylpropane diglycidyl ether monomethacrylate (CDE) containing the fragment of dianic epoxy resin, as well as free carboxy and methacrylic groups has been studied as a component of epoxy-oligoesteric and bitumen-polymeric mixtures. The epoxy-oligoesteric mixtures were investigated using ED-20 dianic epoxy resin, the crosslinking of which was carried out in the presence of polyethylene polyamine. Physico-mechanical properties and chemical stability of the coatings based on epoxy-oligoesteric mixtures with CDE were determined.
