【Abstract】 By using stearine, lubricating oil in SAE 30 and isopropanol aluminum as feed, aluminum-base grease gels were prepared with one stage method. Through transmission electron microscope investigation, it was showed that the structure character of the gels is a three-dimension meshwork of framework composed from micelles of aluminum-soap, in the interspace of which the dispersing medium is filled. By using a viscometer for investigation of the rheological property of the grease gels, the results were showed that the gels belong to dilatant fluid, and they are as near as Newton fluid when at higher temperature. As the composition of aluminum soap is about 11.2%, the apparent viscosity of the gel gets maximum, and at a temperature higher than 40℃, it is showed preferable viscosity-temperature characteristic.更多还原
