中文摘要:
      采用偶联剂Si69包覆改性的淀粉部分替代炭黑,制备改性淀粉/炭黑/天然橡胶(NR)复合材料,并对其性能进行研究。结果表明:与未改性淀粉/炭黑/NR复合材料相比,偶联剂Si69改性淀粉/炭黑/NR复合材料的加工性能改善,滚动阻力降低,物理性能、压缩疲劳性能和耐热空气老化性能提高,耐磨性能下降;改性淀粉在NR基体中的分散性改善。
英文摘要:
      The starch was surface-modified by coating coupling agent Si69, and the modified starch/carbon black/NR composite was prepared.The properties of composite were investigated and compared with the unmodified starch/carbon black/NR composite.The results showed that, the processability of the composite with modified starch was improved,the rolling resistance was decreased,the physical properties,compression fatigue property and thermal aging property were improved,and the abrasion resistance was decreased.In addition,the dispersion of starch in NR matrix was improved after modification.
