| Title of the article | The Influence of Modifier Dispersion on Tribological and Adhesive Properties of Epoxy Polymers |
| Abstract. | Problem Statement. To extend the service life of concrete and reinforced concrete structures, the application of protective polymer-based coatings is crucial and necessary. The primary requirements for this class of materials include high wear resistance and good adhesion to the substrate. In modern practice, epoxy polymers modified with metal oxides are widely used. The properties of the resulting material mainly depend on the type and concentration of the filler, its degree of dispersion, and surface characteristics. The aim of the work is to study the effect of micro- and nano-sized zinc oxide particles on the tribological and adhesive properties of epoxy polymer. The objectives of the study are to substantiate the choice of modifiers and evaluate their impact on the tribological and adhesive properties of epoxy polymers. Results. The paper presents the results of determining the tribological and adhesive parameters of epoxy polymers modified with zinc oxides of various dispersity. The best performance characteristics were demonstrated by epoxy polymers with nano-zinc oxide, in particular, it was possible to increase the shear and peel strength by 14% and 18%, respectively, as well as hardness and abrasion resistance by 10%. The roughness changes more significantly in coatings with micron-sized zinc oxide, demonstrating the greatest profile irregularity height. Conclusions. The significance of the obtained results for the construction industry lies in the possibility of increasing the durability of concrete and reinforced concrete structures through the application of wear-resistant epoxy polymers. |
