Abstract

We modified epoxy resin-based polymer solutions to increase durability in aggressive environments and to reduce costs. We achieved the objective via filling them with the multifractional mineral frame and modification with zeolite and furfural. We varied a content of furfural, a total content of the mineral frame and a proportion of individual components in the frame. The investigated compositions should work under conditions of influence of mixtures of water with oil products and other agents (in elements of structures for the transport service). We determined properties of compositions after exposure separately in air, in water and in two types of oil.

We applied an iterative procedure of random scanning of fields of material properties in five coordinates of varying factors in search for optimal compositions. We studied property fields using experimental statistical models obtained in field experiments. ES models serve to implement calculation experiments using the Monte Carlo method.

We confirmed the possibility for determining the optimal (by the set of criteria) multicomponent polymer compositions for different operating conditions using an iterative procedure of random scanning of property fields.

We obtained compositions for repair and protection of structures, which are in contact with water: paste (reduced viscosity composition without sand) and solution (with reduced epoxy resin consumption). We used compositions that ensure the preservation of the required properties of a protective solution after prolonged exposure to mixtures of water with oil products in the complete overhaul of railway crossing flooring
