技术领域
本发明涉及润滑油的技术领域，具体是一种汽车用润滑油。
背景技术
摩擦会引起高温、高压、噪音、磨损等表观现象，其中危害最大是磨损，磨损直接影响机械设备运转情况和使用寿命。为减缓机械摩擦现象，相继发展了润滑油技术、磁悬浮技术等。
润滑油能够有效减缓摩擦现象，同时兼具冷却降温、密闭隔离等作用。而随着汽车工业的发展和更为严格环保法规的出台，通过添加清洁、高效的车用润滑油成为提高汽车性能、减少环境污染的重要手段。
汽车零部件具有精密复杂且数量众多的特点。结合其严苛的工作环境对车用润滑油的性能提出了更高要求。
为满足车用润滑油在抗氧化性、黏温性、低温流动性、极压耐磨性等性能要求，众多添加剂被广泛添加到基础油中。
然而，合理调配添加剂以全面均衡的满足汽车用润滑油在抗氧化性、黏温性、低温流动性、极压耐磨性等性能上的要求仍存在技术挑战。由于汽车用润滑油工作时长期暴露在空气中，且承受磨损压力，因此具备更为优异的抗氧化性和极压耐磨性成为发展方向。
发明内容
本发明提出了一种汽车用润滑油，其包括如下质量百分含量的组分：抗泡剂：0.1%-3%；有机钼：1%-5%；复合抗氧剂：0.1%-5%；聚异丁烯丁二酰亚胺：2%-4%；清净剂：1%-5%；粘度指数改进剂：1%-5%；硼酸盐：0.1%-2%；基础油：余量。
本发明的进一步设置为：所述复合抗氧剂为任基二苯胺、酚酯型抗氧剂、酚类无灰抗氧剂复配而成。
本发明的进一步设置为：所述任基二苯胺、所述酚酯型抗氧剂以及所述酚类无灰抗氧剂的复配比例为：按质量百分比3：1：1。
本发明的进一步设置为：所述清净剂为烷基水杨酸镁、烷基水杨酸钙、硫化烷基水杨酸镁中的一种或多种。
本发明的进一步设置为：所述有机钼为硫化二烷基二硫代氨基甲酸氧钼。
本发明的进一步设置为：所述抗泡剂为甲基丙烯酸酯。
本发明的进一步设置为：所述粘度指数改进剂为聚α烯烃。
本发明的有益技术效果为：
本发明的汽车用润滑油具有优异抗氧化性和耐磨性能、较好的耐高温性能和黏温性能。同时，有机钼的加入可有效取代部分含磷添加剂，具有环保优点。
具体实施方式
下面描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。
本发明提出了一种汽车用润滑油，其包括如下质量百分含量的组分：抗泡剂：0.1%-3%；有机钼：1%-5%；复合抗氧剂：0.1%-5%；聚异丁烯丁二酰亚胺：2%-4%；清净剂：1%-5%；粘度指数改进剂：1%-5%；硼酸盐：0.1%-2%；基础油：余量。
复合抗氧剂为任基二苯胺、酚酯型抗氧剂、酚类无灰抗氧剂复配而成。复合抗氧剂具有如下效果：
（1）任基二苯胺：高温抗氧性能优良，对抑制油品后期氧化效果显著，配伍性好，与酯酚型抗氧剂复合使用效果提升显著；
（2）酯酚型抗氧剂：配伍性强的辅助抗氧剂，能抑制油品高温氧化和油泥形成，能改善其他清净剂、分散剂和抗氧剂间的相容性、配伍性，增强协同效应；
（3）酚类无灰抗氧剂：高温抗氧化性能优异，兼具控制油泥形成，与其他ZDDP、胺类抗氧剂等助剂复合使用，有协调效应。
任基二苯胺、酚酯型抗氧剂以及酚类无灰抗氧剂的复配比例为：按质量百分比3：1：1。
清净剂为烷基水杨酸镁、烷基水杨酸钙、硫化烷基水杨酸镁中的一种或多种。
有机钼为硫化二烷基二硫代氨基甲酸氧钼。
抗泡剂为甲基丙烯酸酯。
