The invention relates to the technical field of shoe outsole preparation, in particular to an integrally formed shoe outsole and a preparation method thereof, comprising the following steps: (1) preparing a wear-resistant sole: mixing polyurethane wear-resistant sole material evenly, pouring it into a preheated (2) Injection molding: preheat the mold, place the cooled wear-resistant bottom at the bottom of the mold cavity of the mold, and put the polyurethane The midsole material is mixed evenly. After vacuum defoaming, part of it is poured into the mold, then the dried TPU particles are added, and the remaining polyurethane midsole material is poured. Press molding at the gel point to make the polyurethane midsole material hot melt. And it is bonded with the upper surface of the wear-resistant sole to form the midsole of the shoe outsole. The preparation method of the invention replaces the prior art by adopting the integrated molding method of injection molding or hot pressing molding for the midsole and the wear-resistant sole, which shortens the process time, reduces the labor cost, does not need to use glue, and is more environmentally friendly. |
