PRODUCTION METHOD OF SHOE SOLE

摘要

PURPOSE: Provided is a production method of shoe sole which not only produces the shoe sole without causing a peeling between an air bag and a formed polyurethane foam but also easily removes burr formed on the periphery of a window part of the air bag after the molding. CONSTITUTION: The production method of the shoe sole made of a polyurethane foam filled with the air bag includes adhering a urethane reaction accelerator or powders to the window part of the air bag, followed by mounting the air bag in a mold and then, forming the polyurethane foam in the mold. The urethane reaction accelerator is an urethanization catalyst or an oligomer compound having at least 2 active hydrogens in the molecule. The powders have a mean particle diameter of smaller than 50 micrometers.
