Abstract

The invention discloses a preparation method of a hollowed-out high-performance composite sole. The preparation method comprises the following steps: preparing a high-elasticity EVA midsole primary blank, a to-be-vulcanized surface rubber sheet and a to-be-vulcanized high-wear-resistance rubber sheet; preparing a high-wear-resistance rubber outsole, and putting the to-be-vulcanized high-wear-resistance rubber sheet into a rubber vulcanization mold with a hollow pattern design; adhering the surface rubber sheet to be vulcanized to the to-be-vulcanized high-wear-resistance rubber sheet; pastinga non-woven fabric cut into a sole shape on the to-be-vulcanized surface rubber sheet; closing the mold, carrying out mold pressing at 160 DEG C for 120 seconds, opening the mold after rubber vulcanization is finished, slowly taking down the non-woven fabric on the to-be-vulcanized surface rubber sheet to obtain a primary outsole, cooling, and trimming to obtain a high-wear-resistance rubber outsole; and further preparing the high-performance composite shoe sole. The preparation method of the high-performance composite shoe sole with the hollowed-out design has the advantages of light weight,comfort, low cost and the like, and the shoe sole without burrs at the hollowed-out part is designed.

Description

technical field [0001] The invention relates to the technical field of organic polymer compounds, in particular to a method for preparing a high-performance composite shoe sole with a hollow design. Background technique [0002] The hollow design of the bottom pattern of the outsole in the sole not only enhances the fashion sense of the design and creates a sense of jumping, but also reduces the amount of material used in the outsole and realizes the lightweight of the sole, which is very popular among consumers. [0003] figure 1 It is a hollowed-out sole in the prior art. The sole is composed of a midsole 2 and an outsole 1, wherein the outsole 1 is provided with a hollow structure 11. When assembling the sole, the midsole 2 and the outsole 1 need to be pasted on the At the same time, the existing preparation method is usually to apply glue on the side of the midsole 2 that needs to be bonded, and cover the outsole 1 on the side of the midsole 2 that is brushed with glue ...
