With the self-made multifunctional all-electronic rheometer for polymer composites, the effects of data collecting and processing method, calcium carbonate filling content and processing parameters (shear rate, vibration amplitude and vibration frequency) on rheological properties of calcium carbonate filled propylene blends were investigated. And the different effects of data collecting and processing methods as well as vibration parameters on rheological properties of the blends were also discussed in details. The experimental results proves that: different methods to collect and process data will result in distinct apparent viscosity deviation at steady shearing state, and is reduced when being subject to vibration force field. Within lower shear rate zone, the apparent viscosity of the blends goes up dramatically with increasing mass ratio of filled calcium carbonate. However, the effect weakens within relatively higher shear rate zone. Besides, the apparent viscosity declines rapidly with vibration amplitude, and exhibits a sinusoidal trend as vibration frequency increases.
