Description
技术领域
本发明涉及油品技术领域,尤其涉及一种降低CTL基础油空气释放值的方法。
背景技术
CTL基础油,是通过费托合成技术,将煤经合成气转化为混合烃的非石油路线合成的基础油(Coal to liquid,CTL)。针对此类基础油的应用经验尚且不足。
液压系统,曲轴箱系统、汽轮机系统、以及用发动机油控制液压阀、燃料喷嘴等的润滑油产品,由于空气的介入,需要考虑油品的空气释放性,其中基础油的空气释放性,是影响成品润滑油的关键,空气释放性差,会造成大量直径小于1mm的无沫空气夹带于润滑油中,带来众多不利后果,如效率降低,液压部件工作精准度下降、操作噪音大、油温升高、油品老化加速等。
通常情况下,面对空气所带来的问题,会考虑加入抗泡剂来解决,但研究表明抗泡剂无法改善空气释放值。
因此,目前亟需提供了一种降低CTL基础油空气释放值的方法。
发明内容
本发明实施例提供了一种降低CTL基础油空气释放值的方法,通过采用本发明实施例提供的方法,降低了CTL基础油的空气释放值。
本发明实施例提供一种降低CTL基础油空气释放值的方法,包括向CTL基础油中配伍酯类油的步骤。
本发明中,采用CTL基础油配伍酯类油的方法能够有效减少1mm无沫空气夹带于CTL基础油中,降低CTL基础油空气释放值。
根据本发明优选实施例提供的一种降低CTL基础油空气释放值的方法,所述CTL基础油为通过费托合成将煤经CO和/或H2转化为混合烃的CTL基础油;所述CTL基础油的100℃运动黏度为2~20cSt。
根据本发明优选实施例提供的一种降低CTL基础油空气释放值的方法,所述酯类油包括单酯、双酯、或多元醇酯,或其混合物。
根据本发明优选实施例提供的一种降低CTL基础油空气释放值的方法,所述酯类油的配伍质量百分比为0.5%~50%。
本发明中,采用上述方法CTL基础油中配伍酯类油能够降低CTL基础油空气释放值,尤其是100℃运动黏度为2~20cSt的CTL基础油通过与酯类油进行配伍。酯类油包括单酯、双酯、或多元醇酯,或其混合物,在质量百分比为0.5%~50%加入比例下,能够与CTL基础油混合,使得混合后的CTL基础油空气释放值进一步降低,更好的降低空气释放值,能够更好的解决以CTL调配液压油、ATF、涡轮机油等产品时,对CTL基础油空气释放值的要求。
根据本发明优选实施例提供的一种降低CTL基础油空气释放值的方法,所述单酯是由一元酸与一元醇反应制得;优选的,所述单酯中,所述一元酸为油酸或硬脂酸,所述一元醇为C8~C13醇。
根据本发明优选实施例提供的一种降低CTL基础油空气释放值的方法,所述双酯是由线性二元酸与支链一元醇反应制得。
根据本发明优选实施例提供的一种降低CTL基础油空气释放值的方法,所述多元醇酯是由多元醇与一元酸反应制得;优选的,所述多元醇酯中,所述一元酸为C7~C18一元酸。本发明采用上述多元醇酯与体系中其它成分协同配合对CTL基础油空气释放值的降低能够起到更好效果。
根据本发明优选实施例提供的一种降低CTL基础油空气释放值的方法,所述酯类油在100℃下的运动黏度为至少1.5cSt。
根据本发明优选实施例提供的一种降低CTL基础油空气释放值的方法,所述CTL基础油的100℃运动黏度为3~4cSt,所述酯类油为多元醇酯,所述酯类油的配伍质量百分比为50%。
本发明实施例还提供一种所述的降低CTL基础油空气释放值的方法得到的低空气释放值CTL基础油。
本发明至少具有以下优点:本发明通过配伍酯类油,降低了CTL基础油的空气释放值,取得了很好的技术效果。
具体实施方式
以下实施例用于说明本发明,但不用来限制本发明的范围。实施例中未注明具体技术或条件者,按照本领域内的文献所描述的技术或条件,或者按照产品说明书进行。
本发明实施例中,所用仪器等未注明生产厂商者,均为可通过正规渠道商购买得到的常规产品。本发明实施例中所用的原料均为国内润滑油基础油产品市场可买到的常规产品。本发明实施例中,所用多元醇酯是由多元醇与C7~C18一元酸反应制得,双酯是由线性二元酸与支链一元醇反应制得;单酯是由油酸与C8~C13醇反应制得;单酯、双酯、多元醇酯在100℃下的运动黏度≥1.5cSt。
本发明关于基础油空气释放值的评定方法按SH/T 0308进行,即将试样加热到50℃,通过对试样吹入过量的压缩空气,使试样剧烈搅动,空气在试样中形成小泡,即雾沫空气。停气后记录试样中雾沫空气体积减到0.2%的时间,该时间即为空气释放值。
