The invention relates to the technical field of silica gel belts, in particular to a flame-retardant fireproof silica gel belt and a preparation method thereof.Biomass charcoal in modified biomass charcoal powder can serve as a filler of silica gel and can also serve as a carrier of an inorganic flame retardant, so that part of magnesium hydroxide enters a porous structure of the biomass charcoal, and the flame retardance of the silica gel belt is improved; the modified biomass charcoal powder is added into the silica gel, so that the influence of direct addition of the inorganic flame retardant into the silica gel on the mechanical property of the material can be greatly reduced, the compatibility of the modified biomass charcoal powder and the silica gel system is improved by adding gamma-aminopropyltriethoxysilane, the agglomeration phenomenon of magnesium hydroxide and expanded graphene in the silica gel system is reduced, and the mechanical property of the silica gel is further enhanced. The flame-retard
