Embodiment Construction
[0029] refer to figure 1 , the preparation method of the composite sole of preferred embodiment of the present invention comprises the following steps:
[0030] First, in step 101 to step 107, prepare a shoe outsole 1 coated with hot melt adhesive on the surface, referred to as a rubberized shoe outsole 1, such as image 3 shown. refer to figure 2 According to the cross-sectional view of the structure, the preparation method of the rubberized shoe outsole includes: in step 101, a raw rubber 10 is provided, that is, rubber that has not been vulcanized. Next, in step 102 , a layer of hot melt adhesive 11 is coated on the raw rubber 10 . Since the raw rubber 10 itself has a rough surface, the adhesive force between it and the hot melt adhesive 11 can be increased. In step 103 , a release film 12 is covered on the rubber surface of the raw rubber 10 coated with the hot melt adhesive 11 . Next, in step 104, the aforementioned raw rubber 10 coated with hot melt adhesive and t...

The invention relates to a preparation method for a compound type sole. The preparation method comprises the following steps: firstly, providing a foamed shoe insole primary blank and raw rubber; coating the raw rubber with a layer of hot melt adhesive; covering the surface of the raw rubber coated with the hot melt adhesive with a layer of release film and putting into a mould cavity; carrying out hot-pressing vulcanization to cure the raw rubber; after the raw rubber is cured, de-molding and tearing off the release film to obtain a shoe outsole coated with the hot melt adhesive; and finally, putting the shoe insole primary blank and the shoe outsole coated with the hot melt adhesive into a molding mould and carrying out mould pressing and sizing for the second time to obtain a sole finished product, wherein the shoe insole primary blank is compressed into a shoe insole with a small size and fixedly combined with the shoe outsole. The preparation method for the compound type sole is simple in preparation process; the processing cost of downstream shoe manufacturers can be reduced greatly; the bonding strength between the shoe outsole of the shoe insole of the sole finished product can be improved.
Description
technical field [0001] The invention relates to a method for making a shoe sole, in particular to a method for making a composite shoe sole combined with a rubber outsole and a foam shoe midsole. Background technique [0002] At present, the shoemaking industry divides the sole into two parts, the midsole of the shoe on the upper floor and the outsole of the shoe on the lower floor. Among them, the midsole of the shoe is generally made of EVA foam material to provide high cushioning performance, and the material of the outsole of the shoe is mostly rubber to provide wear resistance and anti-slip performance. However, at present, the shoe midsole and the shoe outsole are produced separately by the upstream shoe material company, and then handed over to the downstream shoe factory to assemble into a finished shoe sole by chemical gluing. [0003] In detail, as Figure 7 As shown, the traditional shoe sole manufacturing method is that the shoe factory first obtains a mature sh...
