Abstract

The aim of the study is to design wear-resistant and extrudable polymeric composites based on mixture of UHMWPE+PP with increased tribotechnical characteristics for the wide application in friction units of machine parts and mechanisms as well as using the polymeric resin developed for production of nanocomposites. Adding the block copolymer PP- b -LLDPE into UHMWPE is motivated by the necessity to increase the adhesion between the incompatible polymeric components of the mixture. It is shown that wear intensity of the polymer-polymeric composites UHMWPE+n wt.% PP-b-LLDPE is reduced in contrast with neat UHMWPE. Wherein, an important technological characteristic of UHMWPE - specific extrusion pressure (proportional to the melt flow index) is improved (is lowered). Nanocomposites on the basis of the given matrix have shown wear resistance of 3-4 times higher as contrasted to pure UHMWPE. Permolecular structure and wear track surfaces of nanocomposites on the basis of the polymer-polymeric matrix (UHMWPE+10 wt.% PP-b-LLDPE) were studied. The mechanism of the wear of nanocomposites is discussed.
