Abstract
In the paper, the results of research into the development of polymer composition materials with improved strength and antifriction properties based on high-density polyethylene (HDPE), as well as low- density polyethylene (LDPE) and modifying additives – Azerbaijani clays and synthetic lubricating oil are presented. It was established that the introduction of 5-25% nano-sized clays and 1-3% of the above- mentioned oil into the composition makes it possible to obtain thermoplastic materials with sufficiently high antifriction and other properties. In addition, in the paper the influence of the temperature regime and the pressure of melt extrusion in a material cylinder on the physical-mechanical properties of composites on the basis of propylene were examined. The optimal conditions of processing of multicomponent composites were shown.
