Studying the adhesive interaction between polymer composites and textile material surface

Abstract

The experimental studies on the adhesive interaction of polymer composites are presented in the paper. The objects of the studies are four polymer composites on the basis of acrylic and urethane polymers, crosslinked by the triglycidyl ether of polyoxypropylene triol were formed on the surface of the textile materials of different raw materials composition. When determining the strength of the adhesive bond, the contribution of the physical or chemical factors was considered, since in the adhesive interaction physical and chemical bonds were implemented between the adhesive and the substrate. Based on the mechanical theory of adhesion, the adhesive strength of polymer composites bonding was studied. Polymer coatings, which are formed on the textile material surface, must have high strength properties. Using the method of pulling small strips, it was found that a polymer coating made of a polymer composite number 4 formed on the surface of the cotton textile material (Mitkal art. 125) was characterized by the highest adhesion value. To confirm the formation of the chemical bonds between the adhesive and the substrate, the spectra of reflecting the films of polymer composites on the cotton textile surface were analyzed. It was found that high strength of fixing the film from the polymer composite number 4 on the textile material surface was due to the formation of the chemical bonds between the glycidyl groups of the triglycidyl ether of polyoxypropylene triol and the hydroxyl groups of the fiber cellulose.
