摘　　要：硬脂酸改性纳米碳酸钙分散于DOP中形成的分散体系,具有宾汉流体的流变性能,考察了不同比表面积的改性纳米碳酸钙以及改性剂硬脂酸的不同用量对CaCO3/DOP体系的流变性能的影响,结果表面更高比表面积的纳米钙以及合适的硬脂酸用量分散于DOP中具有更高的屈服值。The CaCO3/DOP system which nano-calcium carbonate was modified by stearic acid shows a rheological property of Bingham fluid. The effect of rheological properly on different specific surface area and different yield of stearic acid was studied. The result shows that： High specific surface area and an appropriate yield of stcaric acid made a high yield point value in the CaCO3/DOP system.
