The invention relates to the technical field of rubber preparation, in particular to a rubber sound insulation material and a preparation method and application thereof, and the rubber sound insulation material is prepared from the following raw materials in parts by weight: 100 parts of polyurethane prepolymer; 15-30 parts of nitrile rubber; 20 to 25 parts of ethylene propylene diene monomer; 10 to 15 parts of polyvinyl chloride; 25 to 50 parts of an ethylene-vinyl acetate copolymer; 4-8 parts of a cross-linking agent; 5-6 parts of stearic acid; 8-10 parts of zinc oxide; the polyurethane prepolymer is prepared from diisocyanate and polyhydric alcohol. The coating further comprises the following raw materials in parts by weight: 2-4 parts of a VOC screening agent, 5-6 parts of white oil and 20-30 parts of carbon black. The rubber sound insulation material with elasticity and high unit dense surface density is prepared from the polyurethane prepolymer, the nitrile rubber, the ethylene propylene diene monomer, the polyvinyl chloride, the ethylene-vinyl acetate copolymer and the cross-linking agent.
