The study of the impact of 4,4'-methylenbis (2-methoxyaniline) on adhesive properties of the epoxy matrix for protective coatings of transport means
Keywords:
adhesive properties, base, epoxy composite, matrix, modifier, residual stresses, strength.Abstract
It is shown that one of the main means of regulating the structure and properties of polymer composites is their physical
modification. It has been proven that the introduction of plasticizers and fillers into the binder makes it possible to improve the
properties of materials.
The effect of the 4,4'-methylenebis (2-methoxyaniline) modifier on the adhesion properties of the epoxy matrix has been
investigated. The optimal concentration of the modifier has been established, ensuring maximum indicators of the adhesive
strength of the matrix when separated from the steel St. 3 base.
The method of IR-spectroscopy established the chemical structure of the modifier, confirming its activity to interact with
the epoxy oligomer in the course of polymerization with a binder. This provides obtaining material not only with improved
adhesion strength, but also with negligible residual stresses.
