装备维保用自润滑聚氨酯摩擦材料研究OA

Friction-lubricated rubber components serve as a critical focus in the maintenance and support of marine equipment,thus demanding targeted research into their composition and performance.In this study,traditional polyurethane materials employed in rubber components are selected as the research subject.An experiment is designed to introduce WS2 and MWNTs as self-lubricating fillers into the material,with the objective of investigating the influence of their synergistic effect on the tribological properties of the polyurethane.Testing results demonstrate that when the addition ratio of WS2 to MWNTs is set at 3∶1,the polyurethane-based composite material exhibits outstanding mechanical and tribological properties.This offers a technical reference for the application of dual-component self-lubricating fillers in the maintenance of marine friction-lubricated rubber components.
