Description
技术领域
本发明涉及耐低温耐磨润滑油的技术领域，具体是一种耐低温耐磨润滑油。
背景技术
在发动机设备运行过程中，润滑油起到润滑、冷却、密封、防锈、减震、卸荷等关键作用，性能优异的润滑油是发动机稳定高效运转的重要保障。性能优异的润滑油可以减少配件磨损、提高设备工作效率、节约燃料和能源，同时也是减少设备运行成本的重要方法。有关研究表明，润滑条件的好坏决定了设备的使用寿命，75%以上的配件损耗都是由于异常磨损造成的，55%以上的设备故障也与润滑条件相关。发动机作为燃油车辆的核心设备,其稳定高效运行性是影响车量使用寿命的关键条件。因润滑性能较弱而导致发动机的零件磨损严重、整车动力性能降低、使用寿命缩短的状况屡见不鲜。另外，在中国三北地区，冬季室外温度可降至-40℃以下，当汽车停驶以后，时间稍长，发动机润滑油便冷却到环境温度。如果润滑油低温性能差，使汽车启动困难、造成磨损加剧。因此，低温性能是评价润滑油性能的一项重要指标。除了通过技术研发提高发动机的性能外,改善润滑性能也是解决发动机磨损失效的重要手段。燃油车辆发动机使用的润滑油除了具备一般润滑性能外，还要求具有抗磨损、冷却、清洁、防锈、抗腐蚀、耐低温、抗氧化、等特性。

通过采用上述技术方案，不仅使油品具备了良好的低温分散性，而且还极大的提升油品的热稳定性与高温清净性。
本发明的进一步设置为：所述聚异丁烯丁二酸酯、所述聚异丁烯丁二酰亚胺的复配比例为1:2.4。
本发明的进一步设置为：所述降凝剂包括聚甲基丙烯酸酯、季戊四醇硬脂酸脂-十八胺-乙酸乙烯酯共聚物。
通过采用上述技术方案，可以有效的降低油品的冷凝点，且对油品的其他性能影响较小。
本发明的进一步设置为：所述聚甲基丙烯酸酯、所述季戊四醇硬脂酸脂-十八胺-乙酸乙烯酯共聚物的复配比例为3:4。
本发明的进一步设置为：所述摩擦改进剂为二烷基二硫代氨基甲酸钼。
本发明的进一步设置为：所述金属清净剂为低碱值的磺酸钙。
本发明的进一步设置为：所述磺酸钙的碱值为150mgKOH/g。
本发明的有益技术效果为：
在此配方下，具有抗磨损、冷却、清洁、防锈、抗腐蚀、耐低温、抗氧化的特性。

根据表1所示四球摩擦磨损试验机的实验结果可知，3种实施例平均摩擦因数均要小于2种对比例，表现出良好的减摩性能；3种实施例的平均磨斑直径在2种对比例的1/2左右，说明实施例的抗磨性能要好于对比例；3种实施例的极压值要高于对比例400N左右，说明实施例的油膜强度要优于对比例；综上所述，该润滑油配方所述方案的润滑油与市面常见发动机润滑油相比，表现出较好的耐磨性能。
润滑油耐低温动力粘度采用GB/T6538-2010发动机油表观粘度的测定冷启动模拟机法进行，分别测定了-10℃、-20℃、-30℃、-35℃、-40℃温度条件下润滑油样品的表观粘度，并对油品性能进行了分析。
表2 不同温度下润滑油样品运动粘度实验结果
根据表2实施例与对比例比较可知，实施例即使在较低温度下也具有较低的表观粘度，表明本配方润滑油低温条件下流动性能更好，具有较好的耐低温性。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件，尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
术语“包括”或者任何其它类似用语旨在涵盖非排他性的包含，从而使得包括一系列要素的过程、物品或者设备/装置不仅包括那些要素，而且还包括没有明确列出的其它要素，或者还包括这些过程、物品或者设备/装置所固有的要素。
至此，优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
