NBR based water-lubricated bearings have attracted tremendous attention with the dramatic oil leakage pollution of oil-lubricated bearings even the implementation of environmentally friendly and ecologically sustainable development strategies. In this paper, MoS₂ and CF are used to reinforce NBR based IPNs composites. Results reveal that the damping factor of fillers/IPNs composites reaches to 0.75 and their effective damping temperature range accomplishes to 50.3 ℃. The minimum friction coefficient and wear rate are 0.033 and 3.09 × 10⁻⁵ mm³/Nm respectively, which is decreased by 51 % and 68 % compared with original IPNs. This indicates that MoS₂ and CF have a brilliant synergistic effect on improving damping and tribological properties of IPNs, which is attributed to the prominent dispersion of CF and its synergistic effect with MoS₂. The knowledge obtained in this work will be promising for preparing water-lubricated bearings materials with excellent damping and tribological performances.

NBR基水润滑轴承由于油润滑轴承严重的漏油污染甚至实施环保和生态可持续发展战略而引起了极大的关注。在本文中，MoS ₂和CF 用于增强基于NBR 的IPNs 复合材料。结果表明，填料/IPNs复合材料的阻尼系数达到0.75，有效阻尼温度范围达到50.3 ℃。最小摩擦系数和磨损率分别为0.033和3.09×10 ^-5 mm ³ /Nm，与原始IPN相比降低了51%和68%。这表明 MoS ₂CF 和 CF 在改善 IPNs 的阻尼和摩擦学性能方面具有显着的协同作用，这归因于 CF 的显着分散及其与 MoS _{2 的}协同作用。在这项工作中获得的知识将有望用于制备具有优异阻尼和摩擦学性能的水润滑轴承材料。
