Review article

The paper presents the results of study of the properties of protective polymer composites based on Ed-20 epoxy resin with the addition of 2d-graphene carbon nanomodifier and triethylenetetramine hardener. Characteristics of protective polymer composites were studied, namely, the effect of the 2d graphene modifier on the viscosity of the epoxy oligomer and on the impact strength of the cured coating. There was investigated the effect of coatings on the performance of 2 compositions of heavy concrete differing in density. The positive effect of epoxy protective coatings on water absorption, frost resistance and compressive strength of heavy cement concretes is shown. 2d-graphene 2d graphene modified epoxy composites have been shown to be more effective than unmodified ones for reducing water absorption.
