Method for manufacturing shoe outsole with TPU high-low-temperature film

Abstract

The invention provides a method for manufacturing a shoe outsole with a TPU high-low-temperature film. A TPU high-low-temperature film sheet is manufactured by adopting tape-casting moulding technology; after the TPU high-low-temperature film sheet is subjected to three-dimensional moulding machining, a three-dimensional film shell structure is formed in the TPU high-low-temperature film sheet; then a TPU film sheet outsole is formed through mould cutting; the TPU film sheet outsole and a insole material can enter a mould jointly for processing, so that an integrated shoe sole composite can beformed through one-step in-mould heating, direct adhesion and joint moulding; a manufacturing process technical problem of traditional manufacturing of rubber outsoles is effectively solved; the shoesole manufacturing method which has the advantages of being simple in manufacturing technique, capable of fully recycling burr waste materials, high in production speed and the like is provided; beneficial effects of shortening a shoe sole production manufacturing process, reducing energy consumption, lowering labor cost, meeting intelligent production and the like are realized; and meanwhile, byutilizing features of a TPU material, a shoe sole manufactured with the TPU high-low-temperature film shoe outsole manufacturing method has more excellent sole wear-resistance, skidding-resistance and soft comfort compared with a traditional rubber shoe sole.

Description

technical field [0001] The invention relates to the technical field of footwear, in particular to a method for preparing shoe outsoles from TPU high and low temperature films. Background technique [0002] The shoe body structure mainly includes the sole and the upper. The sole is divided into a midsole and an outsole. The midsole generally refers to the layer structure that is in contact with the sole of the foot. The layer structure in which the bottom layer is in contact with the road surface. Because the outsole is located at the bottom of the shoe body, it needs to play a good role in anti-slip, wear-resistant, and corrosion-resistant, while the rubber is soft, elastic, resistant to bending, and anti-slip. And wear-resistant and other material properties, so the technology of using rubber as the main material of functional soles has a history of nearly a hundred years, from early natural rubber to artificial rubber including: SBR, NBR, EPDM, BR, IIR, CR, FKM, etc. Wide...

Problems solved by technology

[0005] In recent years, with the development of TPU research technology, TPU products suitable for many fields have been successfully developed, and TPU products have also been used in shoe body manufacturing. However, during the processing of TPU materials, under small temperature changes , the viscosity of TPU melt can change in a large range, which makes its processing only in a small specific temperature range, and its production cost is high, which limits the application of TPU on the shoe body. application
