Description
技术领域
本发明涉及一种耐超高温复合多皂基自修复轴承润滑脂及其制备方法，特别涉及用于石油地质勘探钻井地热、深井、高温领域牙轮钻头使用的复合多皂基自修复轴承润滑脂及其制备方法。
背景技术
随着页岩气、地热深井高温油气勘探的不断发展，行业内对勘探钻探工具的耐高温性能要求也相应不断提高，与之配套的勘探钻井所使用的牙轮钻头，其轴承的耐温性能的要求也更为苛刻。
石油地质勘探钻井使用的油用牙轮钻头，在勘探过程中钻头轴承面临着极高的摩擦生热，钻头轴承的超高压、高冲击负荷，接触面因摩擦产生的高温对钻头轴承润滑脂提出了更高的耐温性要求。钻井高温也会造成润滑脂内部的化学物质之间发生反应，这种润滑脂内部的反应往往会造成润滑脂性能的变化，最终可能导致钻头轴承过早失效，从而危及牙轮钻头使用寿命。
在目前公开的文献资料中，针对环境温度对牙轮钻头轴承润滑脂性能的影响已有相当多的介绍。如美国休斯公司在其钻头轴承测试试验中发现，高温会造成钻头轴承过早失效；斯密斯公司也进行过相似的测试试验，试验结果表明：钻头轴承润滑脂在温度达到150℃后，其本身的极压抗磨性能会急剧下降。
本发明是专利ZL 200510120518.X和ZL 201210033794.2的继续与延伸，主要目的是大幅度提高润滑脂的耐温性能。本申请人针对专利ZL200510120518.X和ZL201210033794.2研制的轴承润滑脂进行了相似的高温极压性能测试。参照润滑脂极压耐磨性能评价方法——润滑脂极压性能测定法，SH/T 0202(四球法)和SH/T 0203(梯姆肯试验机法)，ZL 200510120518.X和ZL 201210033794.2的两款专利产品在150℃高温条件下的烧结负荷均为400KG、Timken试验仅为40 1bf，而重载耐磨试验620kg-900rpm-300s无法完成，证明150℃的高温对润滑脂的性能造成了明显影响，使产品的极压抗磨性能明显下降。如何在保证牙轮钻头轴承润滑脂本身性能不下降的同时让牙轮钻头轴承润滑脂拥有更高的耐温性能就成为目前润滑材料领域的技术难题。
本发明充分考虑到专利ZL 200510120518.X和ZL 201210033794.2中采用的基础液、稠化剂和添加剂本身的耐高温性能，同时充分考虑到不同组分或原料间的相互反应作用，在此基础上，本申请对原专利中的基础液、稠化剂、添加剂配方均进行了优化，通过采用高温稳定性更好的原材料并考虑原材料间相互配伍作用，使本申请所提供的润滑脂在基本性能不下降的前提下，较大幅度提升润滑脂的耐高温性能。

本申请为提高润滑脂的耐高温性能，对原专利中的基础液、稠化剂、添加剂配方均进行了优化，在维持牙轮钻头轴承润滑脂优异的极压、耐磨性能的同时，大幅度提高润滑脂的耐高温性能。本专利所属产品在综合性能上更加优异，耐高温性能更加突出，极压性能维持较高水平。
本发明具有的技术特点：一是在ZL 201210033794.2专利基础上，通过对原专利中的基础液、稠化剂、添加剂配方进行优化，在维持牙轮钻头轴承润滑脂优异的极压、耐磨性能的前提下，提高润滑脂的耐高温性能；二是采用的复合合成基础液，由几种高温性能优良同时性能各有补充的合成基础油组成一种复合合成基础液，其中新引入了合成多元醇酯和合成偏苯酯基础油原料，使润滑脂产品的高温稳定性和高温润滑性得到明显改善；三是采用的复合型稠化剂，与ZL 201210033794.2专利一样，将复合钙基稠化剂作为基本稠化剂，更为不同的是，为了加强稠化剂本身的耐高温性能，本专利所属复合型稠化剂引入了部分有机膨润土稠化剂与复合钙基稠化剂复合成复合型稠化剂，由于膨润土稠化剂的高温稳定性极佳，在高温环境下其本身皂纤维结构十分稳定，且可将其他组分物质分散在其皂纤维结构中防止高温下发生反应，因此，对提高润滑脂性能的高温稳定性起到积极作用；四是采用的惰性极压抗磨添加剂与ZL 201210033794.2专利一样仍然采用了二硫化钨、极化石墨等，更为不同的是，为提高润滑脂高温极压抗磨性能，采用了氮化硼、纳米碳酸钙作为极压抗磨添加剂，并对不同的极压抗磨添加剂进行了合理配比。
本发明的有益效果在于：
1.本发明采用了高温稳定性更好的复合合成基础液、复合型稠化剂、惰性极压抗磨添加剂等原材料，使润滑脂具有优异的极压、耐磨性能的同时提高润滑脂耐温性能。随着我国未来油气勘探的发展，对勘探技术的要求也相应提高。针对地热井、深地层油气勘探，普通牙轮钻头轴承润滑脂产品在高温环境下，其产品性能会急剧下降，最终可能导致钻头轴承过早失效，从而危及牙轮钻头使用寿命。因此，提高牙轮钻头轴承润滑脂自身的耐高温性能，是保证牙轮钻头轴承在高温环境下正常运转的必要条件。本发明通过提高原材料自身的耐高温性能，如本专利采用的复合合成基础油高温蒸发损失更低、复合型稠化剂的高温稳定性更好、惰性极压抗磨添加剂的高温极压抗磨性能更好。同时对不同原料之间的协同作用进行了合理配伍，如采用的复合合成基础液能同时适合复合钙基润滑脂和膨润土基润滑脂；而惰性极压抗磨添加剂的搭配也使其对产品极压抗磨性能的改善效果达到最佳，高温和常温条件下的烧结负荷均能达到800kg。因此本发明专利润滑脂产品在维持牙轮钻头轴承润滑脂优异的性能和满足环保要求的前提下，提高润滑脂的耐高温性能。
2.本发明采用多种高温性能优良的合成基础油调配成复合合成基础液，利用不同类别合成基础油的特性，按不同比例进行调和，使最终的复合合成基础液具有极高的粘度指数，极高的闪点，优异的高低温稳定性能同时，能更好的与稠化剂、添加剂进行协调作用。其中新引入的合成多元醇酯和合成偏苯酯基础油原料，使润滑脂产品的高温稳定性和高温润滑性得到明显改善。
3.本发明采用复合型稠化剂，一种以复合钙基稠化剂与有机膨润土稠化剂复合的复合型稠化剂，该复合型稠化剂在保持复合钙皂极压高承载、抗水的特性外，通过有机膨润土稠化剂的引入，有效的提高了润滑脂高温结构稳定性，从而提高润滑脂的耐高温性能。
4.本发明采用多种惰性极压抗磨添加剂配伍使用。其采用的惰性极压添加剂为微米级，325目筛网通过率90％，有效含量99％；采用的极化石墨耐磨添加剂为微米级，平均粒径5～15um，有效含量99％；采用的氮化硼为微米级，平均粒径10～30um，有效含量99％。采用的碳酸钙为纳米级，平均粒径20～30nm，有效含量60～70％。；
5.本发明采用的胺型、酚型或酚胺型抗氧抗腐蚀添加剂与苯三唑衍生物、噻二唑衍生物或杂环化合物添加剂组成金属钝化剂有很好的协同效应，能有效克服现代钻头轴承技术中采用的有色金属合金如焊铜合金而面临的抗腐蚀问题。
6.本发明采用自修复复合型添加剂，按重量计包含纳米金属粉末类物质如银、铜、锌填充剂0～8份，还包含羟基硅酸镁聚合物0～5份或氟碳聚合物或聚四氟乙烯0～5份，还包括铋、锆的氧化物或乙烯基化合物0～10份。以上极压添加剂、耐磨添加剂、自修复添加剂协同作用后形成的复合型极压耐磨添加剂能够完成使润滑脂摩擦磨损性能达到极其优异程度，按照润滑脂极压耐磨性能评价四球烧结负荷高于800KG，Timken试验超过100 1bf，重载耐磨试验620kg‐900rpm‐300s低于1.45mm。
7.本发明润滑脂在维持牙轮钻头轴承润滑脂优异的极压、耐磨性能的前提下，有效提高润滑脂的耐高温性能。产品工作锥入度不高于340mm 1/10，6万次工作锥入度不高于370mm1/10，滴点不低于330℃，极压烧结负荷高于800kg，综合磨损指数大于160，抗擦伤能力大于100 1bf，200℃条件下的极压烧结负荷不低于800，200℃的高温蒸发损失不高于5％。
总之，本发明是ZL 200510120518.X专利和ZL 201210033794.2专利延伸与发展，主要是采用了高温稳定性更好的原材料，如复合合成基础液、氮化硼和轻质碳酸钙等惰性极压添加剂等，使润滑脂具有优异的耐高温温性能，从而有效满足钻头轴承的耐高温适用范围，尤其适于在石油地质钻探领域中地热井、深地层的牙轮钻头轴承中使用，对于提高牙轮钻头轴承使用温度范围具有十分重要意义。
