Description

一种环保型轴承润滑脂组合物
技术领域
本发明涉及润滑脂技术领域，具体涉及一种环保型轴承润滑脂组合物。
背景技术
润滑脂是指半固态的润滑剂，包括以矿物油、植物油和/或其它流体润滑剂乳化的增稠剂，典型地是皂类。润滑脂具有很高的初始粘度，主要满足低转速、高负荷、长周期润滑保护环境。
润滑脂也通过润滑抗磨作用防止表面腐蚀和机械磨损从而保护机械润滑机构，润滑脂帮助分散热量、隔绝固体和液体污染物，并且减少噪音。因此润滑脂除了具有润滑效果外，一般都具有防锈、冷却、清洁、密封和减振等功能。充足的润滑允许设备平稳持续运行，仅有轻微的磨损并且在例如轴承等部件处没有过多的应力或咬粘。当润滑失效时，部件会破坏性地彼此摩擦，造成损坏、发热以及故障。润滑失效是由于润滑剂量不足或粘度不够、持久使用而没有补给产生的退化、过高的温度、带杂质污染物的引入、对于特定应用使用不正确的润滑脂、和/或过度润滑所造成的。
为了确保机构正确地润滑，所用润滑脂对于特定应用必须精确地选择并且施用正确量，以正确的频率施用到润滑机构的正确位置。比如对于轴承来说，影响润滑脂选择的因素例如包括轴承旋转速度、工作温度范围、运行噪音条件、再次润滑间隔、密封、初始扭矩、载荷、运行条件以及环境影响等。
然而现有技术中的润滑脂，其摩擦系数仍然偏大，动润滑运行一定时间后，两相互运动构件之间的润滑效果降低，会出现磨损伤痕，需要定期更换和维修，比较耗时费力，增加了维护成本，而且现有润滑脂基本上不具备自动修复磨损伤痕的能力。
