摘要

采用熔融共混和模压成型工艺制备超细硫酸钡（BaSO₄）和轻质碳酸钙（CaCO₃）协同增韧聚乳酸（PLA）混杂材料。在保持CaCO₃质量分数恒定的情况下，着重考察了BaSO₄的含量对混杂体系的微观结构、力学性能、熔体流动速率和热稳定性的影响。结果表明：适量BaSO₄的引入在基体中分散均匀且界面结合良好，显著提高了材料的韧性。当BaSO₄的质量分数为15%时，PLA混杂材料的冲击韧度和断裂伸长率较PLA/CaCO₃体系分别提高了60.38%和151.90%。随着BaSO₄含量的增加，拉伸强度逐渐下降，而弹性模量却持续上升。总体上，BaSO₄的引入降低了PLA混杂材料的熔体流动速率，但对PLA的热分解行为影响甚微。

Abstract：

The poly (lactic acid) (PLA) hybrid composites consisted of ultra-fine barium sulfate (BaSO₄) and light calcium carbonate (CaCO₃) inorganic particles were fabricated via molten blending and compression molding. The effect of BaSO₄ mass fraction on the morphologies, mechanical properties, and melt flow rate (MFR) as well as thermal stability of hybrid composites were investigated, under the condition of fixed content of CaCO₃. Results show that adequate BaSO₄ is dispersed homogenously in the matrix and the inorganic particle-PLA interfacial adhesion is well. PLA is synergistically toughened significantly by BaSO₄. With 15% content of BaSO₄, the impact toughness and breaking elongation of the PLA hybrid composites are increased by 60.38% and 151.90%, respectively, compared to PLA/CaCO₃ sample. As BaSO₄ increases, the tensile strength decreases monotonically, while the elastic modulus of samples increases. On the whole, the melt flow rate of the composites is decreased with the presence of BaSO₄. However, little effect of BaSO₄ on the thermal behavior of PLA is observed.
