一种密封润滑脂组合物及其制备方法
摘要：
本发明提供了一种密封润滑脂组合物及其制备方法，所述密封润滑脂组合物由包括以下组分的原料制备而成：基础油10重量份～90重量份；稠化剂1重量份～20重量份；填料10重量份～40重量份；所述填料为海泡石。与现有技术相比，本发明提供的密封润滑脂组合物引入特定含量组分的填料，并与其它特定含量组分实现较好的相互作用，得到的密封润滑脂组合物同时具有优异高温性能、耐酸性气体介质性能和密封性能，能够满足油气田管线和阀门的润滑与密封。实验结果表明，本发明提供的密封润滑脂组合物高温性好，与H2S相容性好。
摘要（英）：

The invention provides a packing grease composition and a preparation method thereof. The packing grease composition is prepared from the following raw materials in parts by weight: 10 to 90 parts ofbase oil, 1 to 20 parts of thickening agent and 10 to 40 parts of fillers, wherein the fillers are sepiolite. Compared with the prior art, the packing grease composition which is obtained by introducing the fillers with the specific component content and realizing good interaction with other components with specific content has excellent high-temperature property, acidic gas medium resistance andsealing property, and can meet lubricating and sealing of an oil-gas field pipeline and a valve. The experiment result indicates that the packing grease composition provided by the invention has highhigh-temperature property and high compatibility with H2S.
