METHOD FOR MANUFACTURING RUBBER COMPOSITION, RUBBER COMPOSITION, VULCANIZED RUBBER, AND TIRE |
摘要 |
Provided are a method for manufacturing a rubber composition, which method can give a rubber composition provided with excellent reinforcement properties by improving the dispersibility of fibers in a rubber component when the fibers are added to the rubber, a rubber composition obtained using this method, a vulcanized rubber, and a tire. The method is a method for manufacturing a rubber composition comprising short fibers, comprising a dispersion preparation step for preparing a short fiber dispersion by adding the short fibers into a liquid, a mixed dispersion preparation step for preparing a mixed dispersion by adding at least one dispersant selected from the group consisting of carbon black and inorganic compounds into the short fiber dispersion, a mixing step for mixing the mixed dispersion and rubber latex to prepare a rubber-short fiber mixed solution, and a drying step for drying the rubber-short fiber mixed solution to give a rubber composition. |
