| Abstract: |
| In this work，a full formula（fillers included carbon black and silica） wet continuous mixing process was researched，which could overcome the difficulty of mixing carbon black and rubber using the traditional dry mixing process，simplify the processing flow and reduce the dust pollution.The full formula continuous wet mixing process was divided into four stages，which were the preparation of aqueous dispersion of reinforcing fillers and additives，the preparation of carbon black masterbatch，the preparation of silica masterbatch，and the continuous mixing.The results showed that the dispersion of carbon black in the rubber matrix was improved by the grinding process of the aqueous dispersion of reinforcing fillers and additives in the early stage and the continuous mixing in the later stage，so that the physical and dynamic mechanical properties of the vulcanizates were significantly improved than that of the vulcanizates produced by the traditional dry mixing process.At the same time，the problem of dust flying in the dry mixing process was avoided，and thus clean and continuous production of the compound was achieved. |
