Description

一种高温链条油组合物及其制备方法
技术领域
本发明涉及高温链条油技术领域，具体涉及一种高温链条油组合物及其制备方法。
背景技术
链条在使用中有良好的润滑磨损性，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。
高温链条油一般需要满足高温环境下链条运动过程中润滑的需要。它要求油品在使用过程中耐高温，基本无油烟，链条上无油泥和高温氧化的积炭、漆膜，同时保护链条减少链条磨损。由于上述条件的限制，现有技术中的高温链条油一般都是以合成油为基础油进行调配生产和使用。但合成油具有资源紧张、制作成本高等不足，且用它做高温链条油不可再回收利用，造成了大量资源和能源的浪费。
发明内容
本发明的目的在于克服上述现有技术的不足，提供一种高温链条油组合物及其制备方法，该链条油组合物具有良好的耐温性，高温工况下的渗透润滑性、抗磨性、耐锈蚀、防腐性能优异，挥发质损失较低，结焦少且焦质会溶解到新油中，不会带来污染，适合大规模工业化生产。

优选地，所述高温抗氧化剂为烷基二苯胺、苯基α-萘胺、硫氮杂蒽、烷基苯基α-萘胺中的一种或多种的混合物。
