Abstract:
      The research progress of intrinsic self-healing rubber materials was introduced.The damage of intrinsic self-healing rubber materials could be repaired by using theirself reversible cross-linking reaction，and they could be repaired several times without adding any repair agents.The self-healing methods based on reversible non-covalent bonds included using the formation of cross-linking network arising from hydrogen bond，ionic bond and coordination bond to realize self-healing of rubber materials，the self-healing methods based on reversible covalent bonds included using the Diels-Alder reaction and disulfide bond reversible reaction to realize self-healing of rubber materials，and the epoxidation of rubber material could realize self-healing of rubber materials too.The intrinsic self-healing rubber materials could be repaired and recycled for many times，and the repair proportion of self-healing rubber materials prepared by different methods was different，and it was hoped that the rubber materials with good physical properties and self-healing properties could be prepared by suitable technology.
