Influence of 2,4-diaminotoluene modifier on the physical and mechanical properties of epoxy composite coatings
Journal Title: Вісник Тернопільського національного технічного університету - Year 2018, Vol 91, Issue 3
Abstract
In the work for the formation of composite material with advanced physical and mechanical properties an epoxy dyanoic oligomer ED-20, a polyethylene polyamine (PEPA) and a modifier of 2,4 – diaminotoluenes were used. The dependence of the content of 2,4 – diaminotoluene on the physical and mechanical properties of epoxy composites is studied. For forming a protective coating with advanced cohesive properties, the optimum content of the modifier is q = 1,0 parts, by which the ability to withstand static, dynamic, and stress shock is increased. The method of the IR-spectral analysis revealed the adsorption and catalytic activity of the modifier, which provides interaction with the side groups of the chain of the epoxy oligomer, which increases the cohesive strength of the materials.
