以硬脂酸、SAE 30润滑油和异丙醇铝为原料 ,采用一步法 ,并添加甲基硅油制备含硅铝基润滑脂凝胶 .通过电镜观察表明该凝胶的结构特征为由铝皂微粒构成空间网络骨架 ,并在其空隙中填充分散介质形成凝胶 ,且硅油的进入未改变空间网络的基本骨架 ,但却使其结构更加致密 .应用粘度计对其流变性的研究表明该凝胶属涨塑性流体 ,并在温度较高时接近Newton流体 ,当硅油质量分数在 2 .5 %时 ,润滑脂表观粘度最小 ,且在 30℃以上时呈现较好的粘温性能
Using stearic acid, SAE 30 lubricating oil and aluminum isopropoxide as raw materials, using a one-step method and adding methyl silicone oil to prepare silicon-containing aluminum-based grease gel.Electron microscopy showed that the structural features of the gel is aluminum soap Particles form the space network skeleton, and the interspace filled with dispersion medium to form a gel, and the entry of silicone oil does not change the basic skeleton of the space network, but to make it more compact structure.Application of viscometer rheological studies have shown that the condensate The plastic is up plastic fluid, and close to the Newton fluid at high temperature, when the silicone oil content of 2.5%, the apparent viscosity of the grease minimum, and more than 30 ℃ when the viscosity-temperature performance
