FIELD: polymers. ^ SUBSTANCE: invention relates to the development of new machine engineering materials working in self-lubrication regimes in slipping friction and can be used as an antifriction material in machine friction units. The composition comprises the following components, wt.-%: polypropylene, 70.7-74.6; stearic acid, 3-9; iron powder, 8-9.5, and cenospheres, 10.9-13.8. The proposed composition provides reducing friction coefficient and enhancing abrasion to wear. ^ EFFECT: valuable properties of composition. ^ 3 ex |
