Abstract
本发明属于液力传动油技术领域，特别涉及一种环保节能的液力传动油组合物，包括以下重量百分比的组成：加氢异构基础油40~60%，合成油10~35%，多元醇酯5~30%，液力传动油复合剂8~16.1%，粘度指数改进剂3~10%，抗氧剂0~2%，降凝剂0.2~2%，抗泡剂0.1~1%；相对于现有技术，本发明在组合物中添加了多元醇酯，提高了液力传动油的抗氧化性能和润滑性能，减少了设备的磨损和延长油的使用期限，从而减少对能源的浪费。另外，多元醇酯的加入，还可提高使用过的液力传动油的生物降解性，使之容易被分解，减少了对环境的污染。
Description
技术领域
本发明属于液力传动油技术领域，特别涉及一种环保节能的液力传动油组合物。
背景技术
液力传动油又称自动变速器油(ATF)或自动传动油，用于由液力变矩器、液力偶合器和机械变速器构成的车辆自动变速器中作为工作介质，借助液体的动能起传递能量的作用。
随着汽车制造业的不断发展，汽车变速器不断升级更新，对液力传动油也不断提出更高的要求。而目前液力传动油多为矿物质油，耐用性和环境友好性一般。
在世界不断发展，资源、能源不断消耗的今天，如何高效地利用有限资源，成为一个共同研究的主题。目前，节约能源的简单方法是减少对能源的使用量和延长事物的使用期限。而在变速器技术领域中，想要节约能源最直接的方法就是延长液力传动油的使用周期。
发明内容
本发明的目的在于：针对现有技术的不足，而提供一种环保节能的液力传动油组合物，以提高液力传动油耐用性和环境友好性，做到节约能源和保护环境。
为了实现上述目的，本发明采用以下技术方案：
一种环保节能的液力传动油组合物，包括以下重量百分比的组成：
其中，其中，加氢异构基础油包括150N的Ⅲ类基础油、100N的Ⅲ类基础油和75N的Ⅲ类基础油，加氢异构基础油在性能上远远超过I类基础油，尤其是具有高黏度指数和很低的挥发性。所述合成油为PAO 4#、6#、8#，所述多元醇酯为三羟甲基丙烷酯或季戊四醇酯。多元醇酯具有氧化安定性与热稳定性能和良好的润滑性，而且容易生物降解、环保友好。在液力传动油调配时，作为添加剂加入调配，可以提高液力传动油的抗氧化性能和润滑性能，减少设备的磨损和延长油的使用期限，从而减少对能源的浪费。少剂量的加入，也可提高使用过的传动油的生物降解性，更容易被分解。
所述的环保节能的液力传动油组合物，还包括按重量百分比计0-2％的金属钝化剂，所述金属钝化剂为N,N'-二亚水杨基-1,2-丙基二胺和二乙基二硫代盐酸中的至少一种。金属钝化剂主要用来抑制活性金属离子(铜、铁、镍、锰等)对油品氧化的催化作用的物质。金属钝化剂和抗氧剂复合使用可提高油品的安定性，延长储存期和使用期。
所述的环保节能的液力传动油组合物，所述液力传动油复合剂为HITEC 3418M复合剂，使用该液力传动油复合剂调出的油品能长期保持性能的优质性。
所述粘度指数改进剂为三嵌段偶合氢化苯乙烯-丁二烯共聚物、聚异丁烯、乙烯-α-烯烃共聚物的至少一种。粘度指数改进剂主要是改善润滑油的黏温性能，提高其黏度指数。其与本发明的其他组分具有良好的相容性，比例选择合适不仅能提高油品的黏温性能，同时还可以使组合物具有优异的抗剪切性能，保证油品在高温、高剪切环境下仍具有适宜的粘度。
所述抗氧剂为双辛基二硫代磷酸锌、二烷基二硫代磷酸锌、2,6-二叔丁基对甲酚、烷基化二苯胺和N-苯基-α-萘胺中的至少一种。抗氧剂通过吸收自由基和分解过氧化物的形式，阻断混合物氧化衰变进程，提高润滑油在高温时候的抗氧化性能，从而起到提高润滑油使用寿命的作用。
所述降凝剂为聚α-烯烃、聚甲基丙烯酸酯和烷基萘中的至少一种。降凝剂的作用机理是与石蜡形成共结晶，改变石蜡晶体的大小和外形，使之不易形成网状结构，起到降低凝固点的作用。
所述抗泡剂为聚甲基硅油和氟代烷基醚中的至少一种。带有气泡的润滑油被压缩时，气泡一旦在高压下破裂，产生的能量会对金属表面产生冲击，使金属表面产生穴蚀，添加抗泡剂可以增快油中泡沫的消除。分散的抗泡剂粒子吸附在泡膜上，然后侵入泡膜成为泡膜的一部分，继而在薄膜上扩张，随着抗泡剂的继续扩张，膜变得越来越薄，最后膜破裂达到破膜目的。
优选的，所述的环保节能的液力传动油组合物，包括以下重量百分比的组成：
更为优选的，所述的环保节能的液力传动油组合物，包括以下重量百分比的组成：
所述的环保节能液力传动油组合物，其制备方法包括以下步骤：
步骤(1)：将加氢异构基础油加入反应釜，预热至50～60℃；
步骤(2)：在步骤(1)反应釜中按上述质量百分比加入多元醇酯、粘度指数改进剂、抗氧剂、降凝剂、抗泡剂、金属钝化剂和液力传动油复合剂，继续加热到60～80℃，并在该温度下持续搅拌1～2小时，使之混合均匀；
步骤(3)：在步骤(2)反应釜中加入合成油，在60-80℃条件下恒温搅拌1～2小时，制得成品。
本发明的有益效果在于：本发明提供一种环保节能的液力传动油组合物，包括以下重量百分比的组成：加氢异构基础油40～60％，合成油10～35％，多元醇酯5～30％，液力传动油复合剂8～14％，粘度指数改进剂3～10％，抗氧剂0～2％，降凝剂0.2～2％，抗泡剂0.1～1％；相对于现有技术，本发明在组合物中添加了三羟甲基丙烷酯这种多元醇酯，提高液力传动油的抗氧化性能和润滑性能，减少设备的磨损和延长油的使用期限，从而减少对能源的浪费。另外，三羟甲基丙烷酯的加入，还可提高使用过的液力传动油的生物降解性，使之容易被分解，减少了对环境的污染。
具体实施方式
