[0003] However, the negative effect of the good adhesion between the airbag and the polyurethane foam is that the burr of the polyurethane foam produced on the edge of the air hole portion of the airbag that is installed from the outside is firmly bonded to the airbag. , In order to improve the aesthetics of the appearance, it takes a long time to remove the so-called burrs. When the burrs are dissolved and removed with an organic solvent, the airbag and the sole itself are also eroded by the organic solvent, causing the quality of the sole to decline.

Abstract
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.
Description
technical field [0001] The invention relates to a method of manufacturing shoe soles. More specifically, it relates to a method of manufacturing a shoe sole capable of easily removing burrs formed at air hole portions of an air bag after the shoe sole is manufactured. Background technique [0002] In recent years, light and strong polyurethane foam has been widely used for shoe soles. Among them, in order to reduce the impact on the feet, soles with air cells that can improve the cushioning performance of the soles have been developed. In order to improve the adhesion to polyurethane foam, thermosetting polyurethane is generally used for the airbag. [0003] However, the negative effect of the good adhesion between the airbag and the polyurethane foam is that the burr of the polyurethane foam produced on the edge of the air hole portion of the airbag that is installed from the outside is firmly bonded to the airbag. , In order to improve the aesthetics of the appearance, ...
