Low-odor and low-heat-generation outer protective rubber composition, mixing method and tire

The invention relates to the technical field of new tire materials, in particular to a low-odor and low-heat-generation outer protective rubber composition, a mixing method and a tire. According to the low-odor and low-heat-generation outer protective rubber composition, natural rubber is completely replaced or partially replaced by a natural rubber composite material, the natural rubber composite material comprises a bacteriostatic agent, and the bacteriostatic agent acts on microorganisms before non-rubber components are decomposed by the microorganisms, so that the non-rubber components are decomposed by the microorganisms, and the non-rubber components are decomposed by the microorganisms. The method does not adsorb or remove the generated malodorous gas after the microorganisms decompose the non-rubber components, so that the phenomena of deterioration, mildewing and stinking of the natural rubber are eradicated fundamentally, and the malodorous gas generated by the tire made of the natural rubber is avo
