Description
技术领域
本申请涉及润滑油领域，更具体地说，它涉及一种耐磨抗氧化润滑油及其制备方法和应用。
背景技术
近年来，化工设备日益朝着大型化、高载荷、高温度、高压力(重负荷)的操作方向发展，对空气压缩机的安全可靠性也提出了更高的要求，而要保证压缩机安全可靠工作，其重要环节之一就是选择正确合适的空气压缩机润滑油。
一方面，由于空气压缩机润滑油处在高温高压环境下，与空气长期接触，极易被氧化变质，因此高温氧化安定性是空气压缩机油的主要质量指标，也是本领域技术人员重点关注和研究的性能；另一方面，要在高载荷、高温度、高压力的工况环境中安全运行，空压油仅提升高温氧化安定性是不够的，还需具有极好的抗磨润滑性，以有效保护螺杆、轴承、齿轮等设备，保证压缩机运行寿命，降低能耗等。
但是目前润滑油的抗磨性能和氧化性能的改善是存在矛盾的，抗磨性能的改善，需要加入较多的含S、P元素的极压抗磨剂，如申请公布号为CN 103897790 A的中国专利中添加了0.6％的硫代磷酸含氮衍生物抗磨剂，油品磨斑直径也仅到0.53mm，抗磨性能一般，且过多S、P存在会加速油品氧化，影响油品氧化安定性。申请公布号为CN 111088095 A的中国专利选择纳米金属氧化物替代硫磷抗磨剂作为极压抗磨剂，但抗磨性能没有改善，磨斑直径0.57mm左右，并且纳米颗粒在润滑油中分散性差，不利于长久储存。
因此如何实现氧化和抗磨平衡，尽可能使油品最大限度的发挥出氧化安定性和极压抗磨性能，成为本领域科研人员持续努力的方向。
发明内容
为了同时具有良好的氧化安定性和极压抗磨性能，本申请提供一种耐磨抗氧化润滑油及其制备方法和应用。
第一方面，本申请提供一种耐磨抗氧化润滑油，采用如下的技术方案：
一种耐磨抗氧化润滑油，包括以下重量百分比原料：
含磷抗磨剂：0.01-0.5％，余量为基础油和其它助剂；
其中，所述含磷抗磨剂由以下方法制得：
将二烷基亚磷酸酯和水混合，在30-70℃下搅拌0.5h-72h；
然后升温至80-110℃，搅拌去除游离水，待均一透明时停止搅拌，得到二烷基亚磷酸酯和水反应的含磷抗磨剂；
所述二烷基亚磷酸酯具有以下结构：
其中，R1与R2均为烷基，R1和R2的碳原子数为C1-C20。
通过采用上述技术方案，本申请中选用具有特定结构的二烷基亚磷酸酯，利用其化学性能不稳定的特性，通过与水转化反应方法，制备出的含磷抗磨剂的极压抗磨性能大大增强，而且相较于常用直接将二烷基亚磷酸酯作为抗磨剂使用，常规二烷基亚磷酸酯抗磨剂需要一定的外界条件反应生成亚磷酸铁保护膜发挥抗磨作用，而且在一定载荷等外界条件下也只有一部分发生反应；
而本申请中经过与水反应后的含磷抗磨剂在不同程度的负荷作用下，可以缩短与金属表面反应时间，而且与金属表面接触后参与有效物质更多，提升与金属表面反应的磷利用率，从而可以生成更多的有机亚磷酸铁膜和/或无机亚磷酸铁保护膜，从而更好保护金属表面，极大提升含磷抗磨剂的极压抗磨性能，本申请含磷抗磨剂较常规的硫、磷极压抗磨剂，极压抗磨性能更加突出，而且其在较小添加量下就起到优异的极压抗磨性能，添加量≤0.5wt％，远低于常规1wt％的添加量，降低由于抗磨剂添加导致的氧化安定性损失，从而可以实现低添加量高抗磨性能，减少磷元素与油品高温氧化性能的催化干扰等负面影响，得到氧化安定性和极压抗磨性能均优异的润滑油。
而且，本申请制得的含磷抗氧剂虽然酸值增加，但是不含S、Cl等活性元素，所以对金属部件如铜等不会产生腐蚀，而且本申请最终制得的润滑油不仅抗磨耐磨性能优异，抗氧化性能突出，而且还具有良好的金属腐蚀性、防锈性能、分散清净性，综合性能优异。
可选的，所述耐磨抗氧化润滑油包括以下重量百分比原料：
含磷抗磨剂：0.01-0.5％，更加优选为0.05-0.3％；

通过采用上述技术方案，选用相同烷基的二烷基亚磷酸酯与水反应后得到的含磷抗磨剂的抗磨性能更加优异。
可选的，所述含磷抗磨剂制备时水的添加量为二烷基亚磷酸酯重量的0.1-20％，更加优选为1-15％，所述含磷抗磨剂的酸值在50-600mg KOH/g之间，更加优选在100-300mgKOH/g之间。
通过采用上述技术方案，通过对于水添加量的控制，配合搅拌时间和搅拌温度的控制，制得含磷抗磨剂的酸值在50-600mg KOH/g之间，更加优选在100-300mg KOH/g之间，含磷抗磨剂的酸值代表了二烷基亚磷酸酯和水的反应程度，两者发生转化程度，使得通过本申请方法制得含磷抗磨剂应用的润滑油在酸值满足条件情况下的极压抗磨性能更优，润滑油的综合性能优异。
可选的，所述防锈剂为磺酸盐类抗磨剂。
可选的，所述防锈剂选用二壬基萘磺酸钙、二壬基萘磺酸钡、二壬基萘磺酸钙/碳酸钙复合物中的一种或多种。
通过采用上述技术方案，选用磺酸盐类防锈剂与二烷基亚磷酸酯的转化产物具有较好的配伍性，一方面相对于其他如烯基丁二酸及其衍生物类防锈剂，选用磺酸盐类防锈剂与含磷抗磨剂复配后可以增强含磷抗磨剂在润滑油中的溶解性，制备出外观均一稳定的润滑油；另一方面也有利于降低润滑油的酸值。
可选的，所述抗氧剂选用胺类抗氧剂和酚类抗氧剂中的一种或多种；

性能检测
对本申请实施例和制备例中制得的耐磨抗氧化润滑油进行下表中的性能检测，检测结果如下表1所示：
表1：
续表1：
结合上表1中实施例1与对比例1和对比例2的检测结果，可以看到本申请制备的耐磨抗氧化润滑油中添加低含量特定方法制得的含磷抗磨剂，也具备突出的极压抗磨性能，其中PB值达114kg，磨斑直径在0.45mm，旋转氧弹时间也达到了1900min，具有优异的极压抗磨性能的同时还具有优异的抗氧化安定性能。而且制得的耐磨抗氧化润滑油的铜片腐蚀、防锈蚀等性能表现良好，综合性能优异。
对比例1使用对比制备例1制备的含磷抗磨剂，其用磷酸三甲苯酚酯代替二烷基亚磷酸酯进行了同样的转化反应，但所制备的润滑油PB和磨斑直径都很差，说明其他结构的磷酸酯抗磨剂极压抗磨性能在本发明所述的转化反应中并没有得到明显改善和提升；对比例2使用对比制备例2制备的含磷抗磨剂，其在转化反应中未添加水，所得到的耐磨抗氧化润滑油PB值也远差于实施例1得到的润滑油，说明水是提升二烷基亚磷酸酯极压抗磨性能的一个关键因素。
再结合实施例1与实施例6和实施例7的检测结果，可以看到实施例7中未添加磺酸盐防锈剂时，耐磨性能和抗氧化安定性与实施例1相差不多，原料中起到优异耐磨性能和抗氧化安定性的还主要是通过本申请方法处理后制得的含磷抗磨剂；此外，可以看到实施例7中未添加磺酸盐防锈剂时外观异常呈乳白，不符合润滑油常规外观要求，且酸值偏高，而实施例6中将本申请中二壬基萘磺酸钙防锈剂等量替换为十二烯基丁二酸半酯，十二烯基丁二酸半酯是一款常用的，与本申请中抗氧剂、金属钝化剂等配伍性良好的防锈剂，但是申请人发现实施例6中使用十二烯基丁二酸半酯防锈剂后，制备得到的润滑油外观浑浊，与本申请制备的含磷抗磨剂配伍性差，因此本申请中制备的含磷抗磨剂与本申请中的磺酸盐防锈剂复配才能配制出外观均一的稳定体系。
再参照实施例2与对比例3和对比例4的检测结果，可以看到，对比例3中直接添加二烷基亚磷酸酯，未添加水，也未进行转化反应，其PB值和磨斑直径均远差于实施例2中制得的润滑油，而对比例4中将0.1wt％的二正辛基亚磷酸酯替换为1％添加量的硫代磷酸三甲苯酯，添加量大幅度提升，也是行业内常用于提升油品极压抗磨性能的方法，但是对比例4中制备的润滑油的PB值和磨斑直径虽然相较于对比例3中有所改善，但是提升幅度有限，而且由于含硫磷元素过多，对比例3中的旋转氧弹大幅度下降至1000min以内，抗氧化安定性大幅度降低。
综上，本申请中通过特定方法制得的含磷抗磨剂具备优异的极压抗磨性能、高温氧化安定性，还具有优异的金属腐蚀性和防锈性能。最终本申请中的耐磨抗氧化润滑油可以作为空气压缩机油应用于空气压缩机如无油式空气压缩机、离心式空气压缩机中，也可以应用于其它设备或工况下如移动机等一些对油品抗磨和抗氧化安定性要求较高的压缩机设备润滑。
本具体实施例仅仅是对本申请的解释，其并不是对本申请的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本申请的权利要求范围内都受到专利法的保护。
