The invention discloses a butyl rubber hot melt adhesive with good high temperature resistance, a preparation method and an automobile hole plugging patch applying the butyl rubber hot melt adhesive. The butyl rubber hot melt adhesive is prepared from the following components in parts by weight: 10 to 18 parts of butyl rubber, 1 to 3 parts of ethylene propylene diene monomer, 2 to 4 parts of natural rubber, 11 to 17 parts of polyisobutene, 10 to 15 parts of plasticizer, 32 to 50 parts of filler, 6 to 9 parts of terpene resin, 10 to 15 parts of bromotriazine, 4 to 7 parts of antimony trioxide, 1 to 3 parts of polyamide wax and 0.5 to 1.5 parts of antioxidant. According to the butyl rubber hot melt adhesive disclosed by the invention, the thermodynamic stability, the high temperature resistance, the flame retardance and the anti-sagging performance at high temperature of the butyl rubber hot melt adhesive are greatly improved; the preparation method is simple in operation steps and high in implementation feasibility, other equipment does not need to be additionally arranged in the production process, and direct implementation of production in an existing high-temperature-resistant flame-retardant hole-plugging patch production line is facilitated.
