| Title of the article | Problems of adhesion when bonding high energy substrates |
| Abstract. | In this article theoretical aspects of a problem of durability of adhesive communication are considered at pasting of high-energy substrates. In a problem of adhesion there are two most important questions: formation of structure of polymeric adhesive, and also the nature and estimation of durability of adhesive communication on border «adhesive-substrate». The important role of making structure of polymeric adhesive-structure of interfaces has marked. From a position of the structural organization of cross-linked polymer effective methods of chemical updating of traditional epoxy adhesives «cold» (without heat supply) and «moderated» curing are considered. These methods allow in addition to a grid of chemical bonds in polymer structure to enter polar groups: NH -, -OCO-, -OH and others which cause possibility of increase of adhesive durability and prevent formation of weak interfaces and reduce level of residual strength by updating of hydroxyurethane and compound ether fragments. Data on dependence of molecular mobility, relax processes of cross-lined epoxyhydrourethane and epoxyallyl polymers from the cumulative contribution of chemical and physical grids is cited. These researches have allowed to solve one of the basic problems of adhesive durability – braking of reactions of curing and formations of «fragile» polymers and it is essential to raise cohesive and adhesive durability of epoxypolymer adhesives. |
