Description
技术领域
本发明属于润滑油技术领域，尤其属于加氢型润滑组合物类，具体涉及一种性能满足API SN+标准要求的发动机润滑油组合物。
背景技术
随着我国国民经济的飞速发展，日益严重的环境问题越来越受到业界重视，现阶段实施的国Ⅴ排放及2020年7月实施的国Ⅵ都深刻反映出国家对环境保护治理的决心和方向。随着排放法规要求的苛刻，主机厂在发动机设计上也进行了一系列变革，当前国内外主流的涡轮增压直喷发动机技术在带来高效率的同时也增大了出现低速早燃的几率。
SN+是美国API组织根据发动机设计的变化，为解决出现的低速早燃情况于2018年正式颁布的最新汽油机油规格，该规格的油品相对于SN级别只是增加了抗低速早燃的性能保护，特别适用于目前装配了直喷汽油机的发动机润滑。现阶段能满足API SN+标准要求的润滑油组合物已成为研究热门。
发明内容
本发明的目的在于提供一种润滑油组合物，该润滑油组合物属于加氢型润滑油组合物，其性能满足API SN+标准要求，该组合物在API标准程序Ⅸ抗早燃台架中表现出了优异的抗早燃特性，同时在NEDC节能试验中表现出了优异的节能性，具有优异的抗早燃性能和节能效果。该组合物除可用于有SN+质量级别要求的发动机润滑，还特别适用于对燃油经济性要求比较苛刻，需要有节能效果的润滑机件。
为达上述目的，本发明通过对添加剂机理和配伍性研究，对润滑油组合物中的各类型金属清净剂、无灰分散剂、抗氧抗磨剂进行了重新组合，打破了传统润滑油的清净体系，并配合抗氧、减摩剂的相互作用，在控制油品灰分的同时，保障了清净性、抗氧抗磨性，赋予了润滑油组合物优异的抗早燃特性和节能性，满足直喷汽油机的用油需求。
本发明提供一种润滑油组合物，该润滑油组合物包括以下组分及含量：
组分A：至少两种金属清净剂，1.5-3.0wt％；
组分B：至少一种无灰分散剂，3.0-5.0wt％；
组分C：至少三种抗氧抗磨剂，1.5-3.0wt％；

本发明润滑油组合物的制备方法包括以下步骤：先将按比例所需量的基础油组分H加入带搅拌器的不锈钢调合釜中，升温至60～80℃下搅拌2小时后，将按比例所需量的抗泡剂G加入到调合釜中继续搅拌2小时，再将按比例所需量的降凝剂F、黏度指数改进剂E依次加入到调合釜中继续搅拌2小时，再依次加入按比例所需量的无灰分散剂B、抗氧抗腐抗磨剂C、金属清净剂A、减摩剂D，在60～80℃下继续搅拌4小时，至混合物均匀。
为使本发明的润滑油组合物具备优异的抗早燃特性，同时不会因提高抗早燃性而损失油品的清净性、节能性，本发明对各种添加剂进行了系统全面的考察，发现通过优化清净剂种类及比例，复配特殊的抗氧、分散剂，可在降低油品灰分的情况下，不会造成清净性能的下降。同时通过合理复配抗磨减摩剂，有效避免了清净剂种类变更造成的节能性能下降。在研究过程中，添加剂种类的选择和比例的确定，直接决定了成品油的最终性能表现。例如，金属清净剂的钙盐和镁盐在抗早燃特性表现中呈现了两个相反的结果，钙盐会促进早燃情况的发生，而镁盐会降低早燃的发生。不同清净剂间的组合搭配，呈现出的高温清净性也各不相同。本发明中为使产品具有较好的抗早燃特性，有意降低了产品的硫酸盐灰分，致使配方产品中清净剂含量要低于普通发动机油，清净性能的下降通过和分散剂、抗氧剂的协同作用来弥补。本发明通过多种模拟试验手段，对不同类型添加剂间及同种类型不同组成的添加剂间进行了系统繁杂的筛选和优化复配，通过NEDC、1.5TGDI机械损失、2.0T+/1.5TGDI早燃测试、程序Ⅸ标准台架确定了最终润滑油组合物成分。
本发明调配的润滑油组合物，产品的硫含量为0.20～0.25％(质量)，磷含量为0.06～0.07％(质量)，碱值为7.0～8.0mgKOH/g，硫酸盐灰分为0.65～0.8％(质量)，具有优异的抗早燃特性和燃油经济性，本发明的润滑油组合物能通过SN+标准要求中程序Ⅸ发动机台架试验，在NEDC、1.5TGDI机械损失、2.0T+/1.5TGDI早燃测试中本发明润滑油组合物也表现出了优异的节能性、抗早燃性、清净性。
