Description
技术领域
本发明涉及一种润滑脂，更确切地说，是一种耐高温长寿命的复合锂基润 滑脂及其制备方法。
背景技术
当前，现代工业的迅猛发展对润滑脂性能要求日益严苛，要求润滑脂具有 质量高、性能好和使用寿命长的特点。当前国内应用最多的是锂基润滑脂和复 合锂基脂，锂基润滑脂一般可以在130℃以下长期使用，复合锂基脂可以在150℃ 以下长期使用，与其他润滑脂比较具有经济性好、适用范围广等特点。
氧化安定性能作为润滑脂质量及使用寿命的重要评价指标，润滑脂氧化安 定性及高温稳定性的主要影响因素是基础油、抗氧剂和皂基类型，基础油一般 选择粘度指数高、高温性能好的石蜡基基础油和合成烃型基础油。此外，抗氧 剂可以很大程度上提高润滑脂的高温稳定性及氧化安定性能，高温润滑脂主要 包括复合锂基润滑脂、复合磺酸钙基润滑脂、聚脲基润滑脂等。目前市场应用 最广，产量最大的是复合锂基脂，但其高温氧化性能较聚脲基润滑脂及复合磺 酸钙基润滑脂差，提高复合锂基润滑脂氧化安定性能具有重要意义。
发明内容
本发明主要是解决现有技术所存在的技术问题，从而提供一种耐高温长寿 命的复合锂基润滑脂及其制备方法。
本发明的上述技术问题主要是通过下述技术方案得以解决的：

脂肪酸，5％-20％；
极压抗磨剂，1％-5％；
抗氧剂，3％-15％；
防腐剂，0.1％-2％；
粘度改善剂，0.1％-2％；
其中，以上各个组分的质量百分比之和为100％。
作为本发明较佳的实施例，
所述的基础油包含光亮油基础油和PAO基础油，
所述的抗氧剂包含芳烃衍生物、辛基/戊基二苯胺和烷基对甲酚，
所述的粘度改善剂为乙丙共聚物。
作为本发明较佳的实施例，所述的芳烃衍生物、辛基/戊基二苯胺、烷基对 甲酚的比例为2-40:1:1。
作为优选，所述的芳烃衍生物为烷基多苄基甲苯衍生物，所述的烷基多苄 基甲苯衍生物为傅克烯。
本发明还公开了一种如前述的耐高温长寿命润滑脂的制备方法，其特征在 于，包含步骤：
步骤1、碱液准备，按照一定的比例加入水和一步碱氢氧化锂，将水加热到 85-95℃；在烧杯内按照一定的比例加入水和二步碱氢氧化锂，将水加热到 85-95℃，使氢氧化锂全部融化；
步骤2、将两种基础油调和均匀，按照质量分数，向反应釜中加入50％的混 合基础油，恒温85℃，加入脂肪酸并搅拌，使脂肪酸充分溶化；
步骤3、待脂肪酸溶解后，在94-98℃将一步单水氢氧化锂溶液加入到搅拌 釜内，皂化60分钟，在95℃左右开始滴加二步碱，当反应釜内稠度变稠后，升 温到100-103℃继续滴加，滴加时间在1.5-2小时，滴加完毕，继续升温排水， 升温到165℃，测游离碱，用氢氧化锂溶液或硬脂酸调整至0.02-0.10％NaoH， 调整完毕后继续升温，釜内温度达到211-213℃，停止加热，恒温3-5分钟，恒 温结束后，用剩下的混合基础油进行急冷操作；
步骤4、加入极压抗磨剂，抗氧剂，防腐剂，粘度改善剂，搅拌均匀后研磨 两次，过滤，脱气得到复合锂基脂。
本发明的耐高温长寿命的复合锂基润滑脂及其制备方法具有以下优点：本 发明的润滑脂在添加抗氧添加剂烷基多苄基甲苯衍生物后，润滑脂的氧化诱导 期时间更长，表明氧化安定性更好，极压性能更优。

2.根据权利要求1所述的耐高温长寿命复合锂基润滑脂，其特征在于，
所述的基础油包含光亮油基础油和PAO基础油，
所述的单水氢氧化锂包含一步碱单水氢氧化锂和二步碱单水氢氧化锂，
所述的抗氧剂包含芳烃衍生物、辛基/戊基二苯胺和烷基对甲酚，
所述的粘度改善剂为乙丙共聚物。
3.根据权利要求2所述的耐高温长寿命复合锂基润滑脂，其特征在于，所述的芳烃衍生物、辛基/戊基二苯胺、烷基对甲酚的比例为2-40:1:1。
4.根据权利要求2所述的耐高温长寿命复合锂基润滑脂，其特征在于，所述的芳烃衍生物为烷基多苄基甲苯衍生物，所述的烷基多苄基甲苯衍生物为傅克烯。
5.一种如权利要求2中所述的耐高温长寿命润滑脂的制备方法，其特征在于，包含步骤：
步骤1、碱液准备，加入水和一步碱氢氧化锂，将水加热到85-95℃；在烧杯内加入水和二步碱氢氧化锂，将水加热到85-95℃，使氢氧化锂全部融化；
步骤2、将两种基础油调和均匀，按照质量分数，向反应釜中加入50％的混合基础油，恒温85℃，加入脂肪酸并搅拌，使脂肪酸充分溶化；
步骤3、待脂肪酸溶解后，在94-98℃将一步单水氢氧化锂溶液加入到搅拌釜内，皂化60分钟，在95℃左右开始滴加二步碱，当反应釜内稠度变稠后，升温到100-103℃继续滴加，滴加时间在1.5-2小时，滴加完毕，继续升温排水，升温到165℃，测游离碱，用氢氧化锂溶液或硬脂酸调整至0.02-0.10％NaoH，调整完毕后继续升温，釜内温度达到211-213℃，停止加热，恒温3-5分钟，恒温结束后，用剩下的混合基础油进行急冷操作；
步骤4、加入极压抗磨剂，抗氧剂，防腐剂，粘度改善剂，搅拌均匀后研磨两次，过滤，脱气得到复合锂基脂。
