STUDY OF INFLUENCE OF SMALL ADDITIVES OF SURFACTANTS AND ORGANOSILICON COMPOUNDS ON CURING PROCESSES OF EPOXYAMINE BINDERS

Abstract

Specificity of processing of epoxy oligomers is a combination of curing and manufacturing processes. Therefore, it is extremely important to know the kinetics of the oligomer-polymer transition to create optimal technological curing regimes and to produce polymer epoxy with the specific properties. For this purpose a computer simulation of the interaction of modifying additives with a hardener has been conducted. The obtained data indicate that the speed of the process of structuring epoxy compositions at the initial stage depends on the chemical structure, the level of their intermolecular interaction with ED-20 and amine hardeners. It has been found that, depending on the acid-base properties of the surfactant, they are capable of accelerating or slowing down the flow of the curing reaction.
