The invention discloses an IPU material and a synthesis technology thereof. The IPU material is prepared from components in parts by weight as follows: 40-63 parts of EVA (ethylene vinyl acetate copolymer), 5-20 parts of EPDM (ethylene-propylene-diene monomer) rubber, 1-7 parts of brominated butyl rubber, 0.4 parts of stearic acid, 0.65 parts of zinc stearate, 0.8-1 part of zinc oxide, 0.4-1.1 parts of a crosslinking agent, 0.1-0.6 parts of a high-temperature foaming agent and 0.1-5 parts of toner. Compared with rubber, the IPU material has lighter mass and better wear resistance and slip resistance, is not prone to cracking and frosting, has excellent performance and wearing comfort, the production process is simple, the overall characteristic of the IPU material tends to that the a PU (polyurethane) material, an ejection process is adopted, the production efficiency is effectively improved, the labor force is reduced, modeling is facilitated, and a produced product has clear appearance patterns and is three
