淀粉/炭黑/SBR/BR复合材料的性能研究

采用改性淀粉部分替代炭黑制备淀粉/炭黑/SBR/BR复合材料，研究间苯二酚-甲醛(RF)树脂或偶联剂KH-550改性淀粉对复合材料性能的影响。结果表明：偶联剂KH-550的改性效果优于RF树脂；RF树脂或偶联剂KH-550能够对淀粉和橡胶基体的界面起到增强作用；与加入RF树脂改性淀粉的复合材料相比，加入偶联剂KH-550改性淀粉的复合材料耐磨性能较差，但抗湿滑性能较好。;The starch was modified by resorcinol-formaldehyde (RF) resin or coupling agent KH-550, and the modified starch/carbon black/SBR/BR composites were prepared. The influence of modified starch on the properties of composites was investigated.The results showed that，the modification effect of coupling agent KH-550 was better than that of RF resin,and the interfacial adhesion of starch and rubber matrix could be strengthened by RF resin or coupling agent KH-550.Compared with the RF resin modification，the coupling agent KH-550 modified starch filled composites possessed worse wear resistance and better wet skid resistance
