Abstract
本发明公开了全寿命车辆齿轮润滑油组合物,按质量百分比由以下组分组成:基础油84%~93.6%,降凝剂0.1%~1.0%,全传动系统车辆齿轮油复合添加剂6.0%~12.0%,黏度增长抑制添加剂0.1%~1.0%,酸性组分捕捉剂0.1%~1.0%,油/泥沉积物抑制剂0.1%~1.0%,以上各原料质量百分比总和为100%;其制备方法是将以上组分称取后加入调合釜中,升温搅拌透明即得到本发明组合物。若倾点满足需求,则不添加降凝剂,基础油所占质量百分比为85%~93.7%,其余组分及制备方法如上述组合物。本发明可满足车辆传动系统终身不换油的润滑需求,具有很好的经济效益和社会效益。
Description
技术领域
本发明属于润滑油技术领域,具体涉及全寿命车辆齿轮润滑油组合物,还涉及该润滑油组合物的制备方法。
背景技术
随着汽车技术的发展,其传动部位的润滑条件较过去更为苛刻,例如:齿轮箱体积更小,致使齿轮温度和负荷提高;整车的空气动力学设计降低了变速箱及后桥周围的空气流速,这样能有效提高燃油效率,但同时也使重负荷卡车变速箱工作温度提高了25-30℃;还有缓速器和同步器的应用,使得在同步耐久性、热氧化安定性、抗点蚀性能、抗擦伤性能方面对油品有了更高的要求。这些汽车技术的发展,推动了OEM对高性能车辆齿轮油的需求。润滑油换油周期的延长可以减少车辆用户维修保养频次,提高车辆的有效运行时间,在车辆使用过程中用户的总成本得到有效降低,因此从事物流运输的商用车用户对延长润滑油换油周期的愿望特别强烈,希望少换油,甚至终身不换油的全寿命车辆齿轮润滑油。对于OEM而言,润滑油长换油期技术其一可以提升其产品竞争力,从而实现销量提升;其二有助于减少废弃润滑油的产生,降低对环境影响的同时降低用于处理废弃润滑油的成本。因此,全寿命车辆齿轮润滑油是今后最重要的发展方向。
由于环保和节能的要求,车辆齿轮油需要具备更低的黏度,更加节能,换油期更长,国外很多车辆制造商甚至要求与车辆达到同寿命。比如德国大众、美国通用等汽车公司对车辆齿轮油提出了“全寿命”的要求,国内东风汽车、北汽福田等大型汽车公司与迫切需求长寿命和全寿命的车辆齿轮油,以提高其产品的市场竞争力。常规的API GL-5规格已经不能满足长寿命车辆齿轮油的使用要求,从90年代开始,在API GL-5规格的基础上,相继颁布了手动变速箱用油规格MT-1(PG-1)、重负荷双曲线后桥用油规格PG-2、美军MIL-PRF-2105E规格以及代表目前车辆齿轮油最高水平的SAE J2360规格,SAE J2360规格对车辆齿轮油的使用寿命提出了具体要求,重型车要求通过32万公里行车试验,轻、中型车要求通过16万公里的行车试验。
目前,中国市场上车辆手动变速箱油一般采用满足API GL-4或API MT-1规格要求的车辆齿轮油,车辆驱动桥油一般采用满足API GL-5规格要求的重负荷车辆齿轮油,该类齿轮油在热氧化安定性能、抗擦伤性能、高温清净性、抗剪切性能等方面不能满足车辆变速箱和驱动桥长换油期的需求。
发明内容
本发明的目的是提供全寿命车辆齿轮润滑油组合物,具有优异的极压抗磨性能、热氧化安定性能、高温清净性能、黏温性能、低温流动性能、抗泡性能以及防腐蚀性能;能够满足车辆传动系统润滑油终身不换油的润滑需求。
本发明另一目的是提供上述全寿命车辆齿轮润滑油组合物的制备方法。
本发明所采用的技术方案是,全寿命车辆齿轮润滑油组合物,按质量百分比由以下组分组成:基础油84%~93.6%,降凝剂0.1%~1.0%,全传动系统车辆齿轮油复合添加剂6.0%~12.0%,黏度增长抑制添加剂0.1%~1.0%,酸性组分捕捉剂0.1%~1.0%,油/泥沉积物抑制剂0.1%~1.0%,以上各原料质量百分比总和为100%。
本发明的特点还在于:基础油为茂金属聚α-烯烃合成油、油溶性聚醚合成油、合成环烷烃基础油、多元醇酯类合成油或双酯合成油中至少一种,优选为茂金属聚α-烯烃合成油或合成环烷烃基础油中一种或两种按任意比例复配;
全传动系统车辆齿轮油复合添加剂满足美军规格MIL-PRF-2105E要求。
降凝剂为聚烯烃或聚甲基丙烯酸酯中一种或两种按任意比例复配。
