The invention discloses a fluorochlorine elastomer material with multiple excellent properties and a preparation method thereof. The material is characterized in that pyridine derivatives and fluorine-chlorine atoms on a fluorochlorine elastomer molecular chain are subjected to nucleophilic substitution reaction to form a high-strength ion cross-linked network, and the elastomer material is endowed with high mechanical properties; at the reprocessing molding pressure and temperature or the self-repairing temperature, the ionic groups are dissociated, so that the fluorochlorine elastomer material can be remolded and self-repaired. The preparation adopts a mechanical blending method, and the pyridine derivatives, the fluorochlorine elastomer and other assistants are added into an internal mixer or an open mill, uniformly mixed, and subjected to high-temperature compression molding forming. According to the fluorochlorine elastomer material having multiple excellent properties and provided by the invention, the fluorochlorine elastomer material is endowed with high mechanical properties by the high-strength ion aggregate, the material can be reprocessed and self-repaired by high-temperature dissociation and rearrangement of the ion aggregate, and the definite elongation strength and elasticity modulus can be improved by adding the filler, so that the fluorochlorine elastomer material can meet some special requirements.
