Epoxyaminic binders and composites based on them for construction purposes with improved technological, adhesion, physical and mechanical properties, resistant to climatic factors and aggressive environment were developed in the thesis. To achieve these properties, a complex modification of epoxyamine binders with small additives of surfactants and reactive oligomers is proposed and proved. The influence of the nature of surfactants and organosilicon compounds on the technological, structural, physico-mechanical, adhesive-strength properties of epoxyamine compositions was studied. Based on the calculations and computer simulation, the energy of intermolecular interaction of surfactants with the ED-20 oligomer are determined using semiempirical methods, and some regularities in the variation of rheological properties, wetting capacity, and hardening of epoxyamine compositions from the chemical nature of surfactants are established. The influence of surfactants and organosilicon compounds on surface energy and the work of adhesion of solidified epoxyamine binders and the relationship of these values to the adhesion strength of polymers to glass and steel have been studied. It has been established that the addition 0.5 % of surfactants and organosilicon compounds makes it possible to significantly reduce the viscosity of epoxy oligomers, improve the damping ability, and improve the structural and protective properties of epoxy polymers, but has little effect on their adhesion strength and physico-mechanical properties. It is shown that with the addition of reactive oligomers, especially Laprolat-803 significantly improves wear resistance, bending strength and toughness of the polymer, adhesion strength to various surfaces, but reduce viscosity and slightly improve the wetting power not much effectively, impairs the resistance of the polymer to the liquid. The regularities of the effect of the ratio of the reactive oligomers and surfactants on the adhesion of epoxy-amine compositions to glass and steel are determined. For this, a full factorial experiment was used and the response surfaces were constructed. The acid-base properties of the surface of the fillers used and their effect on the kinetics of hardening of epoxyamine binders were also studied. Based on selected compositions, coatings for protecting wood, metal and concrete surfaces, resistant to operating conditions and to aggressive media, have been developed; A composition for use as an adhesive for three-layer particleboard and expanded polystyrene has been developed, and a composition has been developed for using it as a binder for fiberglass plastics. Studies were carried out on the effect of atmospheric and climatic conditions of operation on the durability of the resulting polymer composite materials.
