The invention belongs to the technical field of organic high-molecular compounds, and in particular relates to a high-elasticity light-weight rubber-plastic foam material with good wear resistance and a preparation method of the foam material. The high-elasticity light-weight rubber-plastic foam material is prepared from the following raw materials in parts by weight: 60-70 parts of EVA (ethylene vinyl-acetate copolymer), 10-20 parts of NR (natural rubber), 10-20 parts of EPDM (ethylene-propylene-diene monomer), 5-7 parts of an abrasion-resistant agent, 2-4 parts of an active agent, 2-4 parts of a lubricating agent, 0.8-1.2 parts of a bridging agent, 1.5-2 parts of a foaming agent, 1-2 parts of ST flocculant and 3-5 parts of CaCO3. The high-elasticity light-weight rubber-plastic foam material has good wear resistance and elasticity and small specific gravity, and is particularly suitable for being applied to soles and the like, so that comfort property is good and service life is long.
