The invention discloses a solvent-free polyurethane environment-friendly material for a basketball. The solvent-free polyurethane environment-friendly material for the basketball sequentially comprises a base material layer consisting of a superfine fiber cloth base, a compact layer, a solvent-free cellular layer formed by solvent-free slurry and a slip-proof surface layer, wherein the compact layer is formed by coating the surface layer of the superfine fiber cloth base with finishing slurry by adopting a reverse roll process. The finishing slurry coats the surface layer of the superfine fiber cloth base with the finishing slurry through the reverse roll process to form the compact layer, the bonding property of the cloth base is improved, then in cooperation with the solvent-free foamingprocess, a cellular layer on the compact layer is formed, and the prepared basketball made of the synthetic material is good in resilience, quite strong in impact resistance and long in service life.
