Lightweight high-strength rubber material as well as preparation method and application thereof

The invention belongs to the technical field of light rubber, and particularly relates to a light high-strength rubber material as well as a preparation method and application thereof. The lightweight high-strength rubber material is mainly prepared from the following raw materials in parts by weight: 30-45 parts of natural rubber, 30-70 parts of isoprene rubber, 5-15 parts of high styrene rubber, 5-20 parts of a lightweight high-strength material, 6-12 parts of fumed silica, 10-20 parts of hollow glass beads and 1-5 parts of a vulcanization crosslinking agent. Wherein the light high-strength material comprises at least one of EVA, LDPE and HDPE; the vulcanization cross-linking agent comprises sulfur and dicumyl peroxide. Therefore, the light high-strength material and the hollow glass beads are matched with each other, so that the specific gravity can be reduced; after the rubber and the light-weight and high-strength material are blended, the performance of the light-weight and high-strength rubber material
