A method of preparing polyester elastomer meltblown nonwoven fabric membrane with porous and high bonding strength includes the following steps of: (a) Adding a reaction solvent to a reaction solvent to thermoplastic polyester elastomer (TPEE) powder or granules to prepare a solvent mixture. (b) Adding a modifier to the solvent mixture, and mixing uniformly to prepare a first mixture, the modifier includes at least one of o-xylylenediamine, m-xylylenediamine, alpha, alpha′-diamino-p-xylene, 2,3,5,6-Tetrachloro-p-xylene-alpha,alpha′-diamine, and 1,3,5,7-Tetraazatricyclodecane. (c) Adding an initiator to the first mixture, and mixing uniformly to prepare a second mixture. (d) Drying the second mixture to form a masterbatch, and (e) preparing the polyester elastomer meltblown nonwoven fabric membrane by passing the masterbatch through a meltblown process.
