Abstract: | Studies show that the mixing process is one of the most critical steps in the rubber processing, which directly affects the performance and service life of rubber products. However, unjustifiable complexity, high processing time, and low mixing quality of the conventional mixing technologies restrict the development of the rubber industry. Aiming at the deficiency of rubber mixing technology at present, the wet mixing technology and continuous mixing technology are complementary to each other, and the continuous wet mixing technology is developed. Then experiments are carried out to evaluate the performance of the proposed method. The obtained experimental results show that the wet mixing and continuous mixing technologies have synergetic effects, thereby simplifying the mixing process and improving the quality and continuity of the mixing process. It is found that the continuous wet mixing technology significantly improves the properties of the rubber compound compared with the conventional dry mixing method. The proposed method not only has reasonable processing properties but also significantly improves the physical, compressive fatigue, degree of dispersion and dynamic mechanical properties of the compound compared with those from the conventional dry mixing process. |
