The application provides a HIFU phantom gel material and a preparation method and application thereof, relates to the technical field of medical functional materials, and the raw material of the HIFU phantom gel material comprises butadiene rubber and dicumyl peroxide (DCP); the amount of dicumyl peroxide is 1%-3% of the mass of butadiene rubber. The HIFU phantom gel material is prepared by using butadiene rubber and a specific amount of dicumyl peroxide crosslinking agent, does not need additional additives, is non-toxic and harmless, has good biocompatibility, and is precisely matched with human soft tissue in mechanical properties and ultrasonic characteristics (sound velocity, acoustic impedance and ultrasonic absorption coefficient), so that the HIFU ablation process and effect can be precisely simulated, and there is no dehydration, shrinkage or mildew phenomenon in long-term use, and the technical problems of the existing HIFU phantom gel material, such as complex components, many additives, complicated process, mismatched ultrasonic characteristics and mechanical properties and poor ablation simulation effect, are solved.
