The sole is bonded by the midsole of the shoe and the outsole of the shoe, and comprises the steps of bottoming, surface modification, spraying glue, bottom bonding, etc., firstly cleaning or baking the shoe midsole and the sole of the shoe or polishing the surface. Then, the modifier is applied, and the surface is modified after baking; then the adsorbent and the sprayed powder glue are coated on the adhesive surface of the sole of the shoe, and the two-in-one treatment agent is sprayed on the adhesive surface under the sole of the shoe, and then baked. After drying, the midsole of the shoe is attached to the outsole of the shoe, that is, the combination of the sole is completed. The shoe is formed by the bonding of the sole and the upper, and includes the steps of cleaning or polishing, modifying, coating the adsorbent and spraying the powder on the midsole; the upper part is firstly treated and then painted. Two-in-one treatment agent, adhesive synthesis and other steps, can complete the production of shoes.

The purpose of the invention is to simplify the step of sizing the sole of the shoe, the outsole of the shoe and the upper of the shoe, so the invention is applied to the sizing agent and the sprayed powder glue when the midsole of the shoe is bonded, and the glue is glued on the upper. The two-in-one treatment agent, which is mixed with the glue and the glue, only needs to be glued on one side, reducing the manual gluing step and the process, not only increasing the production efficiency, but also avoiding the adhesive stain on the upper, which is quite advanced and has Reduce costs.

A further object of the present invention is to reform the traditional application of the adhesive, and to focus on the powder glue, and the powder glue is an uncharged powder. When the joint is coated with the adsorbent, the powder is machined. The glue spraying does not need to be electrostatically adsorbed as the traditional powder, and the two-in-one treatment agent is sprayed under the outsole and the midsole of the shoe, and can be combined into a sole by using a single surface glue. The combination of the sole and the upper is also sprayed with powder glue on the sole, and a two-in-one treatment agent is sprayed on the underside of the upper to replace the sizing, and the single-sided glue can be used to complete the fit of the shoe body.
