Abstract
The present invention relates to a method for preparing a foamed thermoplastic polyurethane elastomer product, comprising the steps of: 1) coating a binder: coating the binder on the surfaces of expandable thermoplastic polyurethane elastomer particles; 2) curing and molding: adding the product obtained from step 1) to a mold and then placing it in a vulcanizing machine for curing and molding; and 3) cooling and setting: cooling the mold after the molding in step 2) to obtain the product of the present invention. By means of pre-coating the binder on the surfaces of expanded thermoplastic polyurethane elastomer particles according to the present invention, the weight of the binder can be reduced, and the properties of the expanded thermoplastic polyurethane elastomer particles can be utilized to the maximum extent.
