The invention discloses a clay/rubber nano composite material prepared from compound modified clay. A preparation method comprises the following steps: adding a cationic modifying agent into inorganic clay, adding an anionic modifying agent after a period of time to prepare compound modified organic clay, and then mixing the compound modified organic clay with rubber and a compounding agent to obtain a rubber and clay nano composite material, wherein the cationic modifying agent is dodecyltrimethylammonium bromide, octadecy trimethyl ammonium bromide or cetyl trimethyl ammonium bromide; the anionic modifying agent is sodium dodecyl sulfonate or sodium dodecyl benzene sulfonate; and 10 parts by mass of organic clay is added into 100 parts by mass of the rubber. Results show that compared with a nano composite material which is prepared from the clay modified by a single cationic modifying agent, the clay/rubber nano composite material prepared from the compound modified clay, disclosed by the invention, has a better micro phase structure and comprehensive mechanical performance.
