Title: RUBBER COMPOSITION AND METHOD FOR PRODUCING SAME
Abstract:
The purpose of the present invention is to provide: a rubber composition which contains a rubber component and cellulose fibers, and which is able to have a good strength under a high strain; and a method for producing this rubber composition. Specifically, the present invention provides a rubber composition which contains modified cellulose nanofibers (component (A)), a rubber component (component (B)) and a surfactant (component (C)); a method for producing a rubber composition, which comprises a step [I] for obtaining a mixture by mixing the component (A) and the component (B), namely the rubber component, and a step [II] for obtaining a rubber composition by adding the component (C) to the thus-obtained mixture and kneading the resulting mixture; and a method for producing a rubber composition, which comprises a step [i] for obtaining a mixture by mixing the components (A), (B) and (C), and a step [ii] for obtaining a rubber composition by kneading the thus-obtained mixture.
