Abstract
The invention relates to a method for manufacturing a shoe composition. The method comprises the following steps: selecting a rubber blank to be formed; coating hot melt adhesives on the blank; cutting the coated blank into a preset shape; putting the cut blank into a mold cavity; closing a mold, heating and pressurizing the mold so as to ripen rubber in the mold; combining the hot melt adhesivesand rubber outsoles after rubber ripening is completed so as to form a footwear outsole with a hot melt adhesive layer by one-step forming; and then, after the temperature of a hot melt adhesive filmis increased by ultraviolet ray or radiofrequency, directly processing the attachment to midsole or a vamp. The method can improve the bonding strength of the hot melt adhesive and the outsole or themidsole, enables the subsequent processing step to be simpler, quicker and easier, and avoids the risk or environmental pollution caused by coating combustible addition agents with volatility.
