摘要
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.
