FIELD: polymers. ^ SUBSTANCE: invention proposes composition polymeric material of tribotechnical designation based on polytetrafluoroethylene, coke and activated magnesium spinel and can be used in machine and mechanisms heavy-loaded friction units. The composition polymeric material comprises the following components, wt.-%: coke, 13.0-14.5; magnesium spinel activated in planetary mill AGO-2 for 2 min, 0.5-2, and polytetrafluoroethylene, the balance. Using the invention allows enhancing longevity and working ability of friction units based on high abrasion resistance, low friction coefficient that are determined by the composition structure. ^ EFFECT: improved and valuable properties of material. ^ 1 tbl |
