Description

合成高温链条油
技术领域
本发明涉及一种润滑油的改进，具体涉及一种高温性能好，且几乎没有积炭和结焦倾向，高温下油品的粘度仍然合理，对设备链条的保护明显更好，同时氧化稳定性好，挥发性低、清洁性好，防生锈性能好、抗磨性能好，润滑性能佳的合成高温链条油。
背景技术
对于链传动，即使链条和链轮设计的非常符合使用条件和环境，但是如果润滑不良，那么想要充分发挥设计的性能和保证使用寿命是不可能达到的。链条在使用中有良好的润滑和润滑不良，其磨损量可相差200-300倍，一旦润滑不充分，则销轴和套筒将发生磨损，并由此引起链条与链轮啮合失调，噪音增大，链节伸长。甚至造成断链事故。滚子与套筒之间润滑不良将造成这些零件早期严重摩损而无法继续使用。
高温行业使用的链条的工作温度基本都在200℃以上，有些行业在250～260℃，甚至会短时间达到280℃，在这样的高温下，一方面，链条油应该极少产生烟雾，更不能产生有害气体，这样会影响整个生产车间的正常生产；另一方面，链条油的粘度就会变得很低，粘附在链条的油膜的很薄，很容易造成油膜破裂导致润滑不良。因此在高温下链条油在链条表面必须有足够的油膜强度来提供润滑，极低的蒸发损失，确保设备的正常使用。
高温热氧化安定性也是高温链条油的重要性能指标之一。链条工作时本身温度高达200℃以上，而且与空气接触，加上使用环境中的水分、杂质等作用，使其很容易被氧化，产生氧化物或油泥，可能促使链条油的粘度增加，而粘度增加会使链条油很难渗透到轴和轴套的内部，这样就不能润滑轴和轴套。另外，氧化后生产的焦质和积炭在链条上，不仅会使能耗增加，增加设备维护是的清理问题和停工时间，更为严重的是会使得链条的润滑完全失效，导致设备故障。因此，要求高温链条油具有极好的热安定性和氧化安定性，极低的积炭和结焦倾向。
发明内容
本发明的目的是提供一种高温性能好，且几乎没有积炭和结焦倾向，高温下油品的粘度仍然合理，对设备链条的保护明显更好，同时氧化稳定性好，挥发性低、清洁性好，防生锈性能好、抗磨性能好，润滑性能佳的合成高温链条油。
