Abstract
A rubber composition manufacturing method in accordance with the present invention comprises an operation in which at least rubber, silica, and silane coupling agent are kneaded in an internal kneader while kneading temperature is controlled so as to suppress occurrence of a coupling reaction between the silica and the silane coupling agent, wherein for at least a portion of time during which the operation is being carried out, at least the rubber, the silica, and the silane coupling agent are kneaded while a ram of the internal kneader is in a nonpressing state.
Claims15
A rubber composition manufacturing method comprising an operation in which at least rubber, silica, and silane coupling agent are kneaded in an internal kneader while kneading temperature is controlled so as to suppress occurrence of a coupling reaction between the silica and the silane coupling agent, wherein
- the internal kneader is equipped with a kneading chamber, a neck portion which is located above the kneading chamber, and a ram which is capable of moving vertically through a space within the neck portion;
- and
- for at least a portion of time during which the operation is being carried out, at least the rubber, the silica, and the silane coupling agent are kneaded while the ram is in a nonpressing state.
