Tribological modification data of Hydrogenated nitrile rubber Nanocomposites for water-lubricated bearing of ship stern shaft

Uniformly dispersed nano-fillers can significantly improve the various properties of rubber materials, but nano-fillers are prone to agglomerate in the process of operation, which affects the modification effect. In this paper, a solution blending masterbatch method was used to prepare Hydrogenated nitrile rubber (HNBR) nanocomposites and the modification effects of ultra-high molecular weight polyethylene (UHMWPE), Nano Graphite (NG) powder, Nano molybdenum disulfide (Nano-MoS2) and Graphite fluoride (GF) on HNBR basic formulation were studied.

The results show that solution blending masterbatch method enables the fillers to be evenly dispersed in the HNBR matrix, and UHMWPE can significantly improve the heavy-duty water lubrication friction properties of the composites. GF has the best modification effect on high-speed water lubrication friction performance, hysteresis heat generation, tensile property and wear resistance. Nano-MoS2 can significantly improve the vulcanization performance.
