The invention relates to the field of foamed rubber, and discloses a foamed rubber composition, vulcanized rubber, and a preparation method and application thereof. The composition comprises a rubber matrix, a filler, a vulcanizing agent, a vulcanization accelerator, a vulcanization activator, a foaming agent and an auxiliary foaming agent, and is characterized in that the rubber matrix contains nitrile rubber, polyvinyl chloride and halogenated butyl rubber, and the addition amount of the halogenated butyl rubber is 25-45 parts by weight relative to 100 parts by weight of the nitrile rubber and the polyvinyl chloride. The foamed rubber material prepared from the raw materials has high aperture ratio, and has good low-temperature resistance and damping and sound-insulating effects. |
