用核桃壳粉和聚丙烯分别在核桃壳含量为40%、50%和60%（重量）的情况下，用和不含马来酸酐接枝聚丙烯制备注射成型样品。随着填料含量的增加，复合材料的弯曲模量和拉伸模量显著增加，而弯曲强度和拉伸强度显著降低。随着填料含量的增加，复合材料的吸水率和厚度膨胀率增加。MAPP提高了核桃壳粉与聚合物基体的界面附着力。核桃壳粉/聚丙烯/MAPP的40/57/3配方可用于需要高尺寸稳定性的户外应用。(C) 2012韩国工业与工程化学学会。Elsevier B.V.版权所有。
Injection molded specimens were prepared from the walnut shell flour and polypropylene with and without maleic anhydride-grafted polypropylene at 40, 50, and 60% (weight) contents of the walnut shell. The bending and tensile modulus of the composites significantly increased with increasing the filler content while the bending and tensile strengths significantly decreased. Water absorption and thickness swelling of the composites increased with increasing filler content. The MAPP improved the interfacial adhesion between walnut shell flour and polymer matrix. A 40/57/3 formulation of the walnut shell flour/polypropylene/MAPP can be used in outdoor applications requiring a high dimensional stability.
