Embodiment Construction

[0015] In order to illustrate the features and effects of the present invention, the following three examples are given for detailed description.

[0016] The method provided by the first embodiment of the present invention is:

[0017] First take a blank to be shaped, such as a rubber blank, coat the blank with hot melt adhesive, then cut the blank into a predetermined shape, such as the shape of a shoe sole, and place the cut blank in the In a mold cavity, then cover the mold and heat and pressurize, so that the rubber in the mold is at 100-180kg / cm 2 , aged at 140-160°C for 3-8 minutes. The pressure, temperature and aging time used in this process can be changed and adjusted according to the composition of the rubber. The best state is 130-150kg / cm 2 , matured for 4-7 minutes at 145-155°C. After the completion, the hot melt adhesive and the rubber outsole can be combined together to form a shoe outsole with a hot melt adhesive layer, and then the hot melt adhesive film c...

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.

Description

technical field [0001] The invention relates to the manufacture of shoes, in particular to a method for manufacturing a shoe composition. Background technique [0002] In addition to one-piece products, the current overall structure of the sole, no matter how many layers of materials it is composed of, is now mostly made of adhering methods, such as rubber or PU (Polyurethane polyurethane) outsole footwear . The most traditional and common way is to prepare a rubber or PU outsole and a midsole respectively, the midsole can be PU (Polyurethane polyurethane) or EVA (Ethylene Vinyl Acetate ethylene vinyl acetate) material, and then the outsole And the bonding surface of the midsole is first polished to make the surface of the bonding surface rough, and then the bonding surface of the outsole and the midsole is glued, dried after the glue is applied, and then the outsole and the midsole are glued together. Put the bottom into the mold cavity and make the two sticking surfaces ...
