    • Method for the production of an initial rubber composition, in the course of which the following steps are carried out in succession: A—a rubber matrix, reinforcing fillers, and other components if required, with the exception of the cross-linking system, are introduced into a mixing means of the internal mixer type, comprising a mixing chamber in which there are mounted rotors which are driven in rotation and have radial projections forming a gap (e) between themselves and the vessel, B—said components are mixed in the chamber until a uniform mixture is obtained, care being taken to ensure that the temperature of the mixture remains at or below 170° C., after which C—the rotation speed of the rotors is adjusted so as to bring the rubber composition to a dropping temperature in the range from 180° C. to 240° C., in a time of less than 600 seconds, and preferably less than 400 seconds, and D—when the dropping temperature has been reached, the initial rubber composition is removed from the internal mixer and the temperature of said composition is brought below 140° C. in less than 5 minutes.
    • 生产初始橡胶组合物的方法,其中连续进行以下步骤:除了交联体系之外,如果需要,A-橡胶基质,增强填料和其它组分是 引入内部混合器类型的混合装置,包括混合室,其中安装有旋转驱动的转子,并且具有在它们与容器之间形成间隙(e)的径向突起,B-组分混合在 室,直到获得均匀的混合物,注意确保混合物的温度保持在或低于170℃,然后调节C - 转子的旋转速度以使橡胶组合物滴下 温度在180℃至240℃的范围内,在小于600秒,优选小于400秒的时间内,D - 当达到下降温度时,初始橡胶组合物为rem 从内部混合器中取出,并将所述组合物的温度在不到5分钟的时间内低于140℃。
