研究了炭黑N330和白炭黑与NR/BR的相互作用及其对补强的影响。炭黑N330与NR/BR相互作用的化学交联密度占40%,对拉伸强度的贡献率为82.8%;白炭黑/偶联剂KH-846与NR/BR相互作用的化学交联密度占66.7%,对拉伸强度的贡献率为80.7%;炭黑/白炭黑/偶联剂KH-846与NR/BR相互作用的化学交联密度约占70%,对拉伸强度的贡献率约占94%。3种补强体系对拉伸强度的贡献都是化学作用占优势,贡献率超过80% |
英文摘要: |
The interactions between filler and rubber and their effect on reinforcement were investiga-ted.The results showed that the chemical crosslinkage accounted for 40% in the interactions between N330 black and NR/BR and its contributive rate to tensile strength was 82.8%;the chemical crosslinkage accounted for 66.7% in the interactions between silica/coupling agent KH-846 and NR/BR and its contributive rate to tensile strength was 80.7%;and the chemical crosslinkage accounted for 70% in the interactions between black/silica/coupling agent KH-846 and NR/BR and its contributive rate to tensile strength was about 94%.The chemical crosslinkage gave prevailing contribution to the tensile strength for all 3 reinforcing systems with over 80% of contributive rate. |
