Description

一种低温抗磨液压油
技术领域
本发明涉及一种抗磨液压油，具体地说是一种低温抗磨液压油。
背景技术
液压油是利用液体压力能的液压系统使用的液压介质，在液压系统中起着能量传递、系统润滑、防腐、防锈、冷却等作用，由于叶片泵、柱塞泵的操作压力不断上升以及对摩擦副的磨损，对于液压油提出了各种需求，尤其是在铝箔或铜带轧制中对轧机的液压系统用油有更高要求，如：对轧制油无污染，能延长轧制油的使用周期；能够降低因工件染色而引起的产品报废率；具有较好的抗磨损性能；具有优异的抗氧、抗腐性能，不腐蚀金属；粘度适中，能克服泵和液压系统的泄漏，同时较高的黏度指数使油品在高温时不会过度稀释。抗磨液压油可以分为有灰型和无锌型。有灰型抗磨液压油具有很好的抗磨性，能满足叶片泵的使用要求。无锌抗磨液压油在水解安定性、破乳化性，过滤性、热稳定性和氧化安定性方面优于含锌抗磨液压油。
随着液压机械的发展和大范围的使用，以及人类对环境恶劣地区的开发，液压系统将面临更多的来自工作环境的考验，尤其是在极低温环境下的考验，随着温度的降低，油样的粘度逐渐增加，进而影响液压油的各项性能，因此液压系统对抗磨液压油的要求越来越高，现用液压油并不能完全满足现在液压机械的需求。

所述基础油为MVI类基础油和癸二酸二辛酯按照3:1的重量比制成；
所述极压抗磨剂为改性纳米氧化锌、二烷基二硫代氨基甲酸盐、偏硼酸钠按照0.2:1:3的重量比制成。
所述粘度调节剂为乙丙共聚物。
所述抗氧化剂为改性纳米氧化锌和2，6-二叔丁基对甲酚按照1:10的重量比制成。
所述防锈剂为十二烯基丁二酸和苯并三氮唑按照1:2的重量比制成。
