The invention discloses a preparation method for a bactericidal and breathable insole, belonging to the technical field of polymeric materials. The preparation method comprises the following steps: inparts by weight, successively weighing 80 to 100 parts of styrene-butadiene rubber, 20 to 30 parts of a styrene-butadiene-styrene block copolymer, 15 to 22 parts of a modified gel additive, 15 to 25parts of an additive, 5 to 10 parts of essential oil, 8 to 12 parts of dibutyl phthalate, 10 to 18 parts of sulfur and 5 to 12 parts of stearic acid, mixing the styrene-butadiene rubber and the styrene-butadiene-styrene block copolymer, carrying out mastication so as to obtain a pretreated blank material, successively adding the modified gel additive, the additive, the essential oil, the dibutyl phthalate and the stearic acid into the pretreated blank material, and carrying out mixing so as to obtain a blank material, cooling the blank material, mixing the cooled blank material and the sulfur,carrying out vulcanizing a
