Description

矿物油系可生物降解液压作动油
技术领域
本发明涉及IPC分类中C10M105/00以非高分子有机化合物基料为特征的润滑组合物,尤其是矿物油系可生物降解液压作动油。
背景技术
液压油就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、抗磨、系统润滑、防腐、防锈、冷却等作用。对于液压油来说,首先应满足液压装置在工作温度下与启动温度下对液体粘度的要求,由于润滑油的粘度变化直接与液压动作、传递效率和传递精度有关,还要求油的粘温性能和剪切安定性应满足不同用途所提出的各种需求。液压油的种类繁多,分类方法各异,长期以来,习惯以用途进行分类,也有根据油品类型、化学组分或可燃性分类的。
随着人们绿色环保意识逐渐加强和环保法规日益严格,液压油对环境的污染破坏引起各个国家的重视,国际标准化组织(ISO)出台了环境可接受液压油(液)产品规格标准—ISO15380-2011,该规格是世界各国公认的可生物降解液压油的质量标准之一。
环境友好型可生物降解液压油指油品必须满足液压系统使用性能要求,同时,其自身及耗损产物又具有生态效应,包括:无毒性或低毒性、可生物降解性、可再生等。
生物降解液压油是为了适应环保要求,控制环境污染而开发的。生物降解液压油是性能卓越的抗磨损液压油,主要有植物基础油和合成醋,植物油由于具有天然的生物降解性能、优秀润滑性能和粘温性能,而且资源丰富,价格相对低廉,是环保润滑油的主要发展方向,如美国瑞安勃等,由植物油基础油配方而成,可以最终降解。这方面的探索包括:
中国专利申请98809361.8埃克森化学专利公司公开的合成的生物降解的润滑剂和功能液,其含有45—94重%的作为基础润滑油的C5-C10羧酸的酯、5—18重%的作为润滑性能添加剂的C12-C18羧酸的多元醇酯和1—35重%的用于润滑剂和功能液的添加剂整套配方。
中国专利申请201410392026.5中国石油化工股份有限公司公开一种生物降解的植物油基液压油组合物,其包括如下重量百分含量的组分:液压油复合剂2~6%,抗氧剂0.1~0.3%,抗泡剂0.005~0.015%,天然植物油余量。
这一类型的改进技术选择天然植物油为基础油,同时优化配伍抗氧剂、抗泡剂以及液压油复合剂多种功能添加剂,可适用于有环保要求或可生物降解要求的各类设备液压系统的润滑与密封。
另外,中国专利申请201410791829.8公开了一种可降解性液压油及其制备方法,此配方中,不含矿物油,只采用了脂肪酸和醇类物质,成本较为昂贵。
虽然,矿物油系液压作动油中矿物油含量较高,一般在90-99%,基础油较难处理,且处理成本较高,对环境影响恶劣,而且,矿物油基液压油的生物毒性高,一旦泄露会对人体和环境造成危害。但是,由于矿物油系液压作动油成本低适宜普及,而现有技术中少有可生物降解的矿物油系液压作动油。
发明内容
本发明的目的是提供一种矿物油系可生物降解液压作动油,在保证正常加工性能,基本不增加成本的情况下,很大程度的提高对矿物油的生物降解性能。
本发明的目的将通过以下技术措施来实现:配方为:
矿物油:90-96%;
抗磨添加剂:2-7%;
脂肪酸酰胺磷酸酯:1-3%;
粘度指数改进剂:0.1-0.5%
其中,精制矿物油中石蜡基占比50-60%。
尤其是,配方为:精制矿物油:97.2%;
脂肪酸酰胺磷酸酯:1.75%;
抗磨添加剂:0.75%;
粘度指数改进剂:0.3%;
具体制备方法为:
在容器中加入矿物油97.2%、脂肪酸酰胺磷酸酯1.75%、抗磨添加剂0.75%,粘度指数改进剂0.3%,在常压下,加热搅拌30±5min,温度控制在55±5℃,确认透明,制得成品。
本发明的优点和效果:具有优越的抗磨性能、抗氧化性能和抗泡沫性能的同时,不对设备产生腐蚀、锈蚀,并对密封橡胶具有良好的适应性。生物降解性达到90%以上,可满足装置精密液压系统的高液压、高输出泵的严格要求,也能应付液压系统其他组件,如低间隙伺服阀门及高精度数控机床等的严格要求。能延长设备的使用寿命,并最有效地保护设备,从而减低保养费和产品处理开支,适用于有环保要求或可生物降解要求的各类设备液压系统的润滑与密封。
具体实施方式
本发明原理在于,尽量做到控制成本最低化。选用具有绿色环保功能且可再生的生物质原料,采用优秀的添加剂来保护液压设备,并添加特殊的脂肪酸酰胺磷酸酯类物质来增加润滑性和矿物油的生物降解性。
下面结合实施例对本发明作进一步说明。
实施例1:优选地,配方为:精制矿物油:97.2%;
脂肪酸酰胺磷酸酯:1.75%;
抗磨添加剂:0.75%;
粘度指数改进剂:0.3%;
具体制备方法为:
在容器中加入矿物油97.2%、脂肪酸酰胺磷酸酯1.75%、抗磨添加剂0.75%,粘度指数改进剂0.3%,在常压下,加热搅拌30±5min,温度控制在55±5℃,确认透明,制得成品。
前述中,矿物油作为选用的基础油为精制直链矿物油,此种矿物油具有优秀的氧化稳定性和润滑性,能够增加油品的使用寿命;抗磨添加剂中,其中一种为二硫代磷酸锌与防锈剂的复合剂,兼具了抗氧化性,抗磨润滑性及防锈性;脂肪酸酰胺磷酸酯类物质,进一步提高了油品的抗磨润滑性,并提对油品的生物降解性有明显的提升生物降解实验以此油品与纯植物油酸做对比,纯植物油酸为完全生物降解型油酸,测量相同条件下此油品的生物降解生成的CO2量与基准物油酸降解生成的CO2量的比值,比值越大,生物降解性越好;实验发现添加了特殊的脂肪酸酰胺磷酸酯的油品,比值可以达到90%以上,具有优秀的生物降解性;粘度指数改进剂为聚甲基丙烯酸酯类物质,极好的提高了粘度指数,确保了油品无论是在高温或者低温下,都能保持良好的使用状态。
虽然,上文中已经用一般性说明及具体实施方案对本发明作了详尽的描述,但在本发明基础上,可以对之作一些修改或改进,这对本领域技术人员而言是显而易见的。因此,在不偏离本发明精神的基础上所做的这些修改或改进,均属于本发明要求保护的范围。
