| Popis: | The paper presents the technology of manufacturing of a double-layered material based on ultrahigh molecular weight polyethylene on one side and an elastomer on the other, which has high adhesive strength between materials. The results of the study of the adhesive interaction of ultrahigh molecular weight polyethylene with elastomers based on various rubbers are presented. The dependence of the strength of adhesive interaction between materials on the diphenylguanidine curing agents content in the rubber compound is shown in the article. It was found that with the addition of diphenylguanidine, the strength of the adhesive bond between the materials exceeds the cohesive strength of the elastomer and the process of delamination at fracture occurs along rubber. The study of the interphase boundary on a scanning electron microscope showed that the addition of diphenylguanidine into the rubber mixture leads to a change in the structure of ultrahigh molecular weight polyethylene to fine-spherulite. Using the method of IR-spectroscopy it was detected the peaks of stretching vibrations, corresponding to C-S bonds, and peaks corresponding to stretching vibrations of R-SO-OR and RO-SO-OR groups with the addition of diphenylguanidine into the rubber mixture in the ultrahigh molecular weight polyethylene structure near the interphase boundary |
