Embodiment 1

[0034] In the present embodiment, described light jogging shoe sole comprises the following steps:

[0035] In order to achieve the above object, the present invention adopts following technical scheme, comprises the steps:

[0036] Step 1: Prepare and recycle EVA film, crush the scraps, defective products, waste products, and scraps produced in the process of producing EVA soles through a crusher; then crush 75 parts by weight of crushed material, 2 parts of mineral oil, and 4 parts of EVA 7870S , banbury in the internal mixer, then open the kneading, and finally calender into a recycled EVA film with a thickness of 0.02mm;

[0037] Step 2: prepare the rice for the sole of the light jogging shoes, the rice for the sole of the light jogging shoes is prepared from the following components in the following parts by weight:

[0038]

[0039] Among them, the preparation method of the silicon-boron elastomer: 140g of hydroxyl silicone oil with a viscosity range of 1500cs and a ...

Embodiment 2

[0044] In the present embodiment, the preparation method of the sole of the light jogging shoes is basically the same as that in Example 1, except that:

[0045] In step 2: the composition of raw materials is different (see Table 1 for details).

[0046]In step 3: mold temperature 180°C, time 140 seconds.

[0047] The light jogging shoe sole that above-mentioned preparation obtains, density 0.22g / cm 3 , hardness 63C, tear strength 7.4N / mm, rebound rate 56%, dimensional shrinkage 1.0%.

Embodiment 3

[0049] In the present embodiment, the preparation method of the sole of the light jogging shoes is basically the same as that in Example 1, except that:

[0050] In step 2: the composition of raw materials is different (see Table 1 for details).

[0051] The light jogging shoe sole prepared above has a density of 0.21g / cm 3 , hardness 61C, tear strength 7.8N / mm, rebound rate 52%, dimensional shrinkage 0.9%.

Abstract

The invention discloses a light jogging shoe sole preparation method, wherein the light jogging shoe sole is prepared from the following raw materials by weight: 58-65 parts of a recovery EVA film, 20-25 parts of EVA, 7-9 parts of graphene oxide, 5-8 parts of maleic anhydride polybutadiene, 1.7-1.9 parts of a foaming agent AC, 0.8-0.9 part of a cross-linking agent BIBP, 1.0-1.3 parts of zinc stearate and 1.0-1.2 parts of stearic acid. The preparation method comprises: internal mixing, open mixing, granulation, and one-time injection molding. According to the invention, the prepared light jogging shoe sole has advantages of light weight, comfort, low cost and the like, and the high-value resource recycling of EVA shoe sole remnant, inferior-quality products, waste products and leftover materials is achieved.

Description

technical field [0001] The invention relates to the technical field of organic polymer compounds, in particular to a method for making soles of light jogging shoes. Background technique [0002] In life, EVA plays an important role in the shoe material industry because of its light weight, high elasticity and low cost. Foaming agents and peroxide crosslinking agents such as dicumyl peroxide (DCP) are added to the EVA foam shoe material formula, and the heating molding process is the chemical crosslinking process between EVA materials. EVA soles are difficult to break and decompose because of their high molecular polymerization degree and strong intermolecular force, resulting in that the shoes made of EVA foamed shoe materials in the prior art are difficult to degrade after being discarded, and long-term accumulation brings environmental problems. Serious pollution, the pollution problems brought about seriously affect the living environment of human beings. [0003] Exist...
