The invention relates to a rubber nano short fiber composite material for an automobile tire and a preparation method thereof. By modifying needle-like silicate through a CO2 supercritical method, the needle-like silicate is dissociated into nano short fiber in the process of mixing with a rubber matrix, and soft carbon black is added. The prepared composite material is used as an automobile tire apex, and has the characteristics of high hardness, high modulus, low heat generation, and excellent processability.
