▎ 摘  要

NOVELTY - The method involves preparing a leather shoe upper surface for leather shoes. Natural leather filling powder and adhesive are taken to prepare a vamp filling material. An inner concave surface is filled with the vamp filling material. An outer upper surface and an inner upper surface of the leather shoe are polished to make the leather shoe upper surface to be smooth. The leather shoe upper surface is bonded with a sole by the adhesive. The prefabricated leather shoe is dried. A heel and an insole are assembled to form a leather product. The adhesive comprises following components such as 45-65 wt.pts of polyether polyol, 1-3 wt.pts of isophorone diisocyanate, 0.4-0.8 wt.pts of phenylpropyl dimethyl siliconalkoxy silicate ester, 10-20 wt.pts of graphene oxide, 8-10 wt.pts of dopamine and 4.4-5.6 wt.pts of thickening agent. USE - Method for manufacturing a persistent solid maintaining natural leather women shoes. ADVANTAGE - The method enables manufacturing a persistent solid maintaining natural leather women shoes with three dimensions in an effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for manufacturing a persistent solid maintaining natural leather women shoes. (Drawing includes non-English language text).
