The invention discloses a preparation method of a magnesium oxide loaded MXene/halogenated butyl rubber composite material, and belongs to the field of nano composite materials. According to the preparation method, firstly, nano particles of magnesium oxide are deposited on the surface of MXene, so that aggregation of MXene sheet layers can be effectively avoided; mXene loaded with magnesium oxide is compounded with halogenated butyl rubber, halogen ions in halogenated butyl rubber and magnesium ions are subjected to metal ion interaction in the high-temperature vulcanization process, and the molecular chain interface effect of MXene and halogenated butyl rubber is enhanced; meanwhile, due to existence of magnesium oxide metal ions, dispersion of MXene in the halogenated butyl rubber is also effectively promoted. In the dynamic use process, the internal friction and damping performance of a rubber system can be effectively improved through mutual friction between MXene lamellas and friction between a large la
