摘要：

Polyformaldehyde (POM)/ethylene-vinyl acetate copolymer (EVA)/high-density polyethylene (HDPE) composites filled with nanometer calcium carbonate (nano-CaCO3) were prepared using a twin-screw extruder. The effects of load and temperature on the melt extrudate swell behavior of the composites were investigated, by using a melt flow rate instrument under experimental conditions, with temperatures ranging from 170 degrees C to 220 degrees C and loads varying from 1.2 kg to 12.5 kg. The results showed that the melt die-swell ratio (B) of the composites decreased linearly with a rise of temperature as the load was fixed, while it increased nonlinearly with increase in the melt volume flow rate (MVR) and load, when the test temperature was constant; they also showed that B is a quadratic function of shear rate or shear stress. The value of B increased nonlinearly with an increase of the HDPE weight fraction (phi) as the temperature was constant, and the temperature sensitivity of B to phi was insignificant, while the effect of load was significant. The correlation between B and phi obeyed a quadratic equation.
