摘要：
The nanometer calcium carbonate filled Polyformaldehyde/ethylene-vinyl acetate copolymer/high-density polyethylene (HDPE) composites were prepared using a twin-screw extruder. The effects of load and temperature on the melt volume flow rate (MVR) and melt density (rho(m)) of the composites were investigated by using a melt flow rate instrument under experimental conditions with temperatures range from 170 to 220 degrees C and loads varying from 1.2 to 12.5 kg. The results showed that the MVR of the composites increased with an increase of temperature and load, while reduced with an increase of the weight fraction (phi) of the HDPE, and the relationship between the MVR and phi was almost consistent with a linear law function. The melt density of the composites increased nonlinearly with an increase of load, while decreased with a rise of temperature. Moreover, the rho(m) of the composites decreased with increases in phi.
