| 中文摘要: |
| 采用湿法制备白炭黑/天然橡胶（NR）母胶，并分别采用NR标准配方和带束层粘合配方制备硫化胶，对硫化胶的性能进行研究，并与干法制备硫化胶性能进行对比。结果表明：湿法白炭黑/NR母胶中白炭黑均匀分散；当采用NR标准配方时，随着白炭黑用量的增大，胶料的门尼粘度和拉伸强度增大，填充10份高分散白炭黑硫化胶的定伸应力、拉伸强度和撕裂强度均明显高于易分散白炭黑硫化胶；当采用带束层粘合配方时，含湿法母胶胶料的加工性能较好，白炭黑用量为10份时，含湿法母胶硫化胶老化后钢丝帘线的粘合力保持率较大，粘合性能较好。 |
| 英文摘要: |
| The silica/NR masterbatch was prepared by wet process method，the vulcanizates were prepared using standard NR formula and belt compound formula，respectively，and the properties of the vulcanizates were investigated.The results showed that，silica was uniformly dispersed in the masterbatch.When the standard NR formula was used，as the addition level of silica increased，the Mooney viscosity of the compound and tensile strength of the vulcanizates increased.The modulus，tensile strength and tear strength of the vulcanizates filled with 10 phr highly dispersible silica were higher than those of the vulcanizates filled with 10 phr easily dispersible silica，respectively.When the belt compound formula was used，the processability of compound with the masterbatch from wet process was better.After aging，the retention rate of adhesion strength between the vulcanizates and steel cord was higher，and the adhesion property was better for the vulcanizates with the masterbatch from wet process. |
