一种润滑脂组合物及其制备方法
摘要：
本发明提供了一种润滑脂组合物包括：硅酸镁稠化剂10份～60份；基础油136份～196份；所述硅酸镁稠化剂的分子式为Si12Mg8O30(H2O)4·8H2O；所述基础油选自烃类油、酯类油、聚醚油、硅油中的一种或几种。本发明使用的硅酸镁稠化剂的分子是由两层四面体二氧化硅单元通过一个中心氧原子和一层不连续的镁原子八面体连接组成的，硅酸镁稠化剂是极性稠化剂，将硅酸镁稠化剂分散在基础油中不需要添加极性分散剂。含有所述硅酸镁稠化剂的润滑脂具有耐高温、良好的机械稳定性和胶体稳定性。本发明还提供了一种润滑脂组合物的制备方法。
摘要（英）：

The invention provides a lubricating grease composite comprising the following components in parts by weight: 10 to 60 parts of magnesium silicate thickening agent and136 to 196 parts of base oil, wherein the molecular formula of the magnesium silicate thickening agent is Si12Mg8O30(H2O)4.8H2O; the base oil is one or more than one selected from hydrocarbon oil, ester oil, polyether oil and silicone oil; the molecule of the magnesium silicate thickening agent used by the invention is formed by connecting two layers of tetrahedron silicon dioxide units through a central oxygen atom and a layer of discontinuous magnesium atom octahedron; the magnesium silicate thickening agent is a polarity thickening agent; the magnesium silicate thickening agent is dispersed in the base oil without adding the polarity thickening agent; and lubricating grease containing the magnesium silicate thickening agent has the advantages of high temperature resistance, and good mechanical stability and colloid stability. The invention also provides a preparation method of the lubricating grease composite.
