THE INFLUENCE OF SHUNGITE ON THE HARDNESS OF A COMPOSITE MATERIAL BASED ON HIGH-PRESSURE POLYETHYLENE

Experimental samples of composite material based on high-pressure polyethylene 16803-070 filled with dispersed shungite, a natural environmentally friendly filler, have been obtained. High-pressure polyethylene and shungite were combined in a single-screw laboratory extruder. The effect of shungite on the mechanical properties of the presented composite material has been established. An analysis of the obtained experimental data has been conducted, which has shown that dispersion of shungite in the binder volume in an amount from 20 to 35 mass. % allows increasing the hardness of high-pressure polyethylene. The studied samples have been subjected to secondary processing. In the process of analyzing its results, the possibility of recycling the obtained material with a deterioration in its mechanical characteristics by no more than 4 % has been revealed
