    摘要: A method for producing a rubber composition, the method including: preparing a modified natural rubber by releasing protein from rubber particles in a natural rubber latex by adding at least one organic compound selected from formaldehyde, paraformaldehyde, formalin, and glyoxal to the above mentioned natural rubber latex and then drying so as to include the released protein therein; and mixing at least one selected from carbon black and silica in this modified natural rubber. Such method reduces viscosity and improves molding processibility of the rubber composition, as well as reducing hysteresis loss.
