Abstract
The influence of the duration of the rubber preliminary vulcanization on the physicomechanical properties, wear resistance and hardness of nitrile butadiene rubber with a thin protective coating from ultra-high molecular weight polyethylene are studied. The optimal duration of the preliminary vulcanization of the rubber providing high adhesive interaction between the rubber and the coating was established. High adhesive interaction leads to an increase in abrasion resistance while maintaining the physical and mechanical properties of the original rubber. Structural rearrangements under uniaxial tension of ultra-high molecular weight polyethylene coated on a rubber surface were visualized using atomic force microscopy. The formation of ordered fibrils on the surface of ultra-high molecular weight polyethylene after 30% elongation is shown.
