Abstract
A method for producing a rubber composition include a mixing step, a drying step, and a dispersion step. In the mixing step, an aqueous solution that includes at least one of oxycellulose fibers and cellulose nanofibers is mixed with rubber latex to obtain a first mixture. In the drying step, the first mixture is dried to obtain a second mixture. In the dispersion step, the second mixture is tight-milled using an open roll to obtain a rubber composition. The rubber composition does not include an aggregate that includes at least one of the oxycellulose fibers and the cellulose nanofibers, and has a diameter of 0.1 mm or more.
Claims3
A rubber composition, comprising:
- at least one of oxycellulose fibers and cellulose nanofibers that are dispersed in the rubber composition in an untangled state,
- the rubber composition obtained by a method comprising:
- a mixing step that mixes an aqueous solution that includes the at least one of oxycellulose fibers and cellulose nanofibers with rubber latex to obtain a first mixture;
- a drying step that dries the first mixture to obtain a second mixture;
- and
- a dispersion step that tight-mills the second mixture using an open roll to obtain the rubber composition.
A rubber composition comprising rubber, and at least one of oxycellulose fibers and cellulose nanofibers that are dispersed in the rubber in an untangled state, the rubber composition not including an aggregate that includes at least one of the oxycellulose fibers and the cellulose nanofibers, and has a diameter of 0.1 mm or more.
