摘　　要：针对炭黑与橡胶混炼难度大以及传统干法混炼工艺繁琐、产生粉尘污染等问题,研究全配方(补强填料包括炭黑和白炭黑)湿法连续混炼工艺。结果表明:全配方湿法连续混炼工艺分为4个阶段,分别为补强填料和小料水分散体的制备、炭黑母胶的制备、白炭黑母胶的制备、连续混炼;全配方湿法连续混炼工艺从初期补强填料和小料水分散体的研磨到后期的连续混炼均促进了炭黑在橡胶基体中的分散,使硫化胶的物理性能和动态力学性能比传统干法混炼工艺硫化胶明显提高,同时避免了干法混炼工艺的粉尘飞扬的问题,可实现胶料的清洁化、连续化生产。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.
