摘要
以天然橡胶(NR)为基体、澳洲坚果壳粉(MNS)为填料,通过双辊开炼制备了澳洲坚果壳粉/天然橡胶(NR/MNS)复合材料,采用红外光谱、热重分析仪、扫描电镜、差热分析仪,万能试验机等表征了MNS及其与NR复合材料的结构和性能,讨论了不同表面改性对MNS/NR复合材料结构与性能的影响。结果表明,硅烷改性改善了MNS与NR之间的相互作用,NR/MNS复合材料的定伸应力、撕裂强度增加;表面改性对NR/MNS复合材料热性能影响不大。
Herein,natural rubber(NR)bio-composites with macadamia nutshell(MNS)have been fabricated via two-roll mixing,and influences of surface modification on the morphology and properties of resulted composites are systematically investigated by Fourier transform infrared spectroscopy,thermogravimetric analysis,scanning electron microscope,differential scanning calorimetry,etc.It has been found that silane enhances the interfacial interaction between MNS and NR,affording the resulted MNS/NR composites with improved modulus and tear strength.In addition,surface modification of MNS show slight influences on the thermal property of NR/MNS composites.
