The invention relates to a high-performance natural rubber vulcanized rubber of a carbon-containing nano-tube, which is prepared by a method comprising the steps of: plasticating the carbon-containing nano-tube with a modified surface and natural rubber together to prepare master batch; adding crude rubber, carbon black, zinc oxide, vulcanized agent and accelerating agent into the master batch, processing the obtained mixture by an open mill or an internal mixer, and obtaining natural rubber mixer modified by the carbon-containing nano-tube; and carrying out vulcanizing processing, and obtaining the modified natural rubber vulcanized rubber. By adding the modified carbon-containing nano-tube into the natural rubber material, the invention leads the comprehensive performances such as wear-resisting property, mechanism strength, anti-aging performance, heat-conducting property, anti-fatigue performance and the like of the natural rubber to be remarkably improved, thus improving the using performance of the natural rubber vulcanized rubber, reducing the using quantity of carbon black, and expanding the application scope of the natural rubber vulcanized rubber.
