硫化温度对丁腈橡胶力学及摩擦学性能的影响
|
摘要
研究低温硫化(100~150℃)对丁腈橡胶物理性能及摩擦磨损行为的影响,运用扫描电镜对丁腈橡胶磨损表面形貌进行分析,探讨不同硫化温度丁腈橡胶的磨损机制。结果表明:随着硫化温度的升高,硫化胶的物理性能(交联密度、拉伸强度、硬度)呈现先升高后下降的趋势,在硫化温度为120℃时,胶料具有较好的综合性能;随着硫化温度的升高,硫化胶的磨损量先减小后增大,在硫化温度为120℃时胶料的磨损量最低,摩擦因数也最低且最稳定;120℃硫化胶的磨损机制主要为磨料磨损,而其他温度硫化胶为更严重的黏着磨损,因此,120℃硫化胶具有优异的抵御黏着磨损的能力。
The physical performances and wear behaviors of nitrile-butadiene rubber( NBR) under the conditions of low curing temperature between 100 ℃ and 150 ℃ were studied. The morphology of worn surface of NBR was measured using scanning electron microscopy( SEM),and the wear mechanism of NBR under different curing temperature was discussed.The results indicate that as the curing temperature increased,the physical performances of NBR,such as crosslinking density,tensile strength and hardness are firstly increased and then decreased,and the outstanding integrated properties is achieved for NBR under the curing temperature of 120 ℃.As the curing temperature increased,the wear loss of NBR is firstly decreased and then increased,and the NBR sample under the curing temperature of 120 ℃ has the lowest wear loss,the lowest and most stable friction coefficient.Abrasive wear is dominating for NBR sample under the curing temperature of 120℃,while the wear mechanism changes from single abrasive wear into worse adhesion wear for the NBR sample under other curing temperature.NBR sample under curing temperature of 120 ℃ exhibits outstanding adhesion wear resistance.
