preparation example Construction

[0039] Some embodiments of the present invention provide a method for preparing a shock-absorbing and rebounding shoe sole as described above, comprising the following steps:

[0040] Melting and kneading the thermoplastic elastomer resin, and then blowing and inflating to prepare a plurality of inflatable elastic pellets;

[0041] The plurality of inflatable elastic balls are stacked and placed in the cavity of the midsole mold, and the bottom of the cavity of the midsole mold is placed with a large bottom. After the mold is closed, microwave or radio frequency is used for heating and bonding, and the mold is opened to obtain a shock-absorbing return. Bouncy soles.

[0042] In the embodiment of the present invention, it is preferable to dry and mix the thermoplastic elastomer resin and processing aids, then put them into the barrel of the twin-screw extruder for melt mixing, and then quickly introduce them into the mold for blow molding and inflate after extrusion to obtain m...

Embodiment 1

[0050] figure 2 It is a schematic diagram of the sole structure provided by Embodiment 1 of the present invention, wherein 10 is the midsole, 20 is the outsole, 30 is the inflatable elastic ball, 11 is the heel area, and 12 is the forefoot area.

[0051] Such as figure 1 with figure 2 As shown, a transparent high shock-absorbing and rebounding sole includes: a shoe midsole 10 with a TPU hollow elastic ball 30 and a wear-resistant and non-slip TPU outsole 20; wherein, the shoe midsole 10 includes a forefoot region 12 and heel area 11. In this embodiment, the forefoot area 12 includes a hollow elastic ball 30 with a diameter of 3 mm and a thickness of 12 mm; the heel area 11 includes a hollow elastic ball 30 with a diameter of 6 mm and a thickness of 24 mm.

[0052] In an embodiment, thermoplastic polyurethane resin (BASF Elastollan 1185A10, hardness 85A, melt index<20g / 10min, 190°C, 21.6kg), and processing aid (0.2 part of antioxidant AT10, nucleating agent silica 1 part,...

Embodiment 2

[0056] Such as figure 1 As shown, a transparent high-shock-absorbing rebound sole includes: a shoe midsole 10 with a TPU hollow elastic ball 30 and a wear-resistant and non-slip TPU outsole 20 . Wherein, the midsole 10 includes a forefoot area and a heel area. In this embodiment, the forefoot area includes a hollow elastic ball 30 with a diameter of 3 mm and a thickness of 12 mm; the heel area includes a hollow elastic ball 30 with a diameter of 3 mm and a thickness of 24 mm.

[0057] In this embodiment, thermoplastic polyurethane resin (BASF Elastollan 1185A10, hardness 85A, melt index<20g / 10min, 190°C, 21.6kg), and processing aids (0.2 parts of antioxidant AT10, nucleating agent silica 1 part, 0.5 part of lubricant zinc stearate), after drying and stirring and mixing, add to the twin-screw extruder barrel and carry out melt mixing, and then quickly introduce it into the mold for blow molding after extrusion to obtain a hollow ball. Among them, the wall thickness of the pe...

Abstract

The invention provides an elastic shoe sole with the shock absorption effect and a preparation method and application thereof. The shoe sole includes a middle sole body and a large sole body, the middle sole body is formed by bonding and stacking a plurality of inflatable elastic small balls, and bonding is achieved by microwave or radio frequency. According to the shape of the foot sole, the middle sole body includes a forefoot area and a heel area, the diameters of the inflatable elastic small balls in the forefoot area are same, and the diameters of the inflatable elastic small balls in theheel area are same. The middle sole body is formed by stacking the plurality of inflatable elastic hollow small balls, the balls are filled with gas, and the small balls forming the middle sole bodyare bonded through the microwave or radio frequency technology. The shoe sole has the advantages of high elasticity, high shock absorption, low compression, low deformation and the like, and the comfort level is improved. Moreover, the preparation process of the shoe sole is simple, the energy consumption is low, and the sole is more environmentally friendly and suitable for industrial popularization.

Description

technical field [0001] The invention relates to the technical field of footwear products, in particular to a shock-absorbing and rebounding shoe sole, a preparation method and application thereof. Background technique [0002] Sports shoe soles usually consist of outsoles and midsoles. The outsole refers to the layer structure that is in direct contact with the ground. It is usually made of natural rubber or artificial rubber and has the functions of anti-slip, wear-resistant and bending-resistant. The midsole generally refers to the structure between the insole and the outsole, which mainly plays the role of shock absorption or rebound. At present, the midsole is mainly made of thermoplastic elastomer materials such as ethylene vinyl acetate copolymer (EVA), styrene-based thermoplastic elastomer (SBS), ethylene octene block copolymer (OBC), and thermoplastic polyurethane (TPU). foam structure. [0003] The shock-absorbing performance of the sole means that when the foot i...
