Description
技术领域
本发明涉及一种发动机油技术领域,具体地,涉及一种发动机油组合物。
背景技术
发动机油在发动机运转过程中平均工作温度为80℃~90℃,最高时可达150℃。当发动机停止运转由于发动机油工作温度迅速降低,冷凝水的生成并混入发动机有种在所难免,特别是在高寒地带温度降低更加迅速上述现象更加常见。此外,醇燃料相对于汽柴油挥发度较高且燃烧生成水量大,发动机油中更易混入乙醇/甲醇和水中,一般非水上用发动机设备或醇燃料中乙醇/甲醇含量小于15%,混入发动机油中的水和醇不超过10%,在该比例条件下很难采用油水分离器或油底壳排水的方法去除水或乙醇/甲醇。发动机油与水分离状态在低温条件下,水层结冰后,一方面增大发动机磨损,另一方面严重影响发动机低温启动性能。发动机油中含有少量水和醇无法从发动机油中分里时,发动机油与水/醇生成乳浊液对发动机是一种润滑保护,因此发动机油具有一定乳化保持性能力显得尤为重要。
业内常用的方法是添加一定量的乳化剂以提高发动机油的乳化保持能力,而乳化剂作为一种表面活性剂与配方中其他表面活性成分如清净剂、分散剂、抗泡剂等存在竞争的关系,影响各自有效组分作用的发挥。
因此,亟需提供一种可以避免添加乳化剂破坏配方平衡且具有一定乳化保持能力的发动机油。
发明内容
本公开的目的是提供一种发动机油组合物,该发动机油组合物可以在保证低温流动性能的同时达到良好的保持能力,从而满足API SN及以上级别规格要求。
为了实现上述目的,本公开提供了一种发动机油组合物,以发动机油组合物的总重量为基准,所述发动机油组合物中包括:0.1-0.4重量%的降凝剂、1.5-8.0重量%的黏度指数改进剂、1.79-3.93重量%的清净剂、0.64-3.07重量%的分散剂、1.04-3.67重量%的抗氧剂、0.01-5重量%的减摩剂、0.3-1.5重量%的二烷基二硫代磷酸锌和余量的中性基础油;所述降凝剂包括醋酸乙烯-富马酸酯类降凝剂,所述醋酸乙烯-富马酸酯类降凝剂中包括:0.4-0.6重量份的富马酸八醇酯、0.8-1.2重量份的富马酸十二醇酯、0.8-1.2重量份的富马酸十四醇酯、0.8-1.2重量份的富马酸十六醇酯和0.8-1.2重量份的富马酸十八醇酯。
通过上述技术方案,本公开提供的发动机油组合物能够满足发动机润滑油的使用要求,特别是在保持一定乳化稳定性及低温性能方面效果良好。
本发明的其他特征和优点将在随后的具体实施方式部分予以详细说明。
