| 英文摘要 | Calcium stearate modified nano-CaCO3 (CaSt-nano-CaCO3) was prepared, and iPP/calcium stearate modified nano-CaCO3 (iPP/CaSt-nano-CaCO3) was prepared by melt blending iPP with CaSt-nano-CaCO3 particles. Compared with pure iPP, the addition of CaSt-nano-CaCO3 and nano-CaCO3 particles both increased flexural strength and flexural modulus of iPP, and impact strength was also improved in these two series composites. In comparison with iPP/nano-CaCO3 the impact toughness of iPP/CaSt-nano-CaCO3 composites was improved slightly, while the flexural modulus of iPP/CaSt-nano-CaCO3 was obviously increased. Differential scanning calorimetry (DSC) and polarized optical microscopy (POM) tests showed that with increasing CaSt-nano-CaCO3 content, the crystallization temperature and the nucleating ability of the composites were all increased. The crystallization temperature of iPP/CaSt-nano-CaCO3 is lower than that of iPP/nano-CaCO3 with the same filler content, indicating that the nucleating ability of CaSt-nano-CaCO3 is weaker than that of nano-CaCO3 in iPP matrix. Wide-angle X-ray diffraction (WAXD) results showed the composites did not exhibit beta crystal form after addition of nano-CaCO3 and CaSt-nano-CaCO3 particles. Compared with iPP/nano-CaCO3 the presence of calcium stearate increases the melt flow rate (MFR) of iPP composite with the same filler content, implying that the processability of the composites will be improved with the modification of nano-CaCO3 with calcium stearate. |
