Problems solved by technology

Disadvantages: heavy weight, easy to spit frost (a quality problem), not easy to corrode (environmental protection problem)
Disadvantages: strong water absorption, easy to turn yellow, easy to break, poor elongation, not resistant to water, easy to rot at the bottom
Disadvantages: easy to absorb water, not easy to corrode, not conducive to environmental protection, easy to get dirty
Disadvantages: not easy to corrode, not conducive to environmental protection, easy to wrinkle and shrink at high temperature
Disadvantages: heavy material, poor wear (not wear-resistant), poor softness, poor bendability (not resistant to folding), poor shock absorption
The length of commonly used chopped aramid fibers is generally 3-5mm, the fibers are intertwined, the dispersion effect is not good when granulating, and the particles with relatively small diameters, the contact area between particles is small, and the cohesion between particles is small , the bond between the friction particles is easy to be destroyed, the particles fall off and the wear rate increases, which affects the friction performance

Embodiment 1

[0033] A sports shoe sole with high abrasion resistance is processed from the following components by weight:

[0034] 20 parts of PPSU, 5 parts of EVA, 5 parts of PETG, 3 parts of polyester polyol elastomer, 2 parts of polycarbonate, 6% of modified aramid fiber with a length of 20-30 μm, modified aramid microfiber with a length of 20-30 μm It is obtained by modifying poly-p-phenylene terephthalamide fiber. The processing steps are as follows: poly(p-phenylene terephthalamide) is dissolved with concentrated sulfuric acid and degassed; the processed hot material enters the grinding equipment together with a certain proportion of nano-scale additives, and is dispersed to the micron level after grinding; The final micron-scale hot material enters the coagulation bath to form, and then forms the finished product of modified aramid fiber through water washing, alkali washing, water washing and heat treatment. The grinding equipment adopts a ball mill, and the total mass of the mixt...

Abstract

The invention relates to a sports shoe sole and a preparation process thereof, in particular to a sports shoe sole with high wear resistance and a preparation process thereof. The sports shoe sole isprepared by processing the following components in parts by weight: 20-65 parts of PPSU, 5-15 parts of EVA, 5-18 parts of PETG, 3-5 parts of polyester polyol elastomer, 2-8 parts of polycarbonate and6-10% of modified aramid fiber with the length of 20-30 microns.. The sports shoe sole has the beneficial effects that the material of the sports shoe sole is prepared by compounding the commonly usedsole material with the pretreated aramid fiber, thus overcoming the defects of the aramid fiber and fully utilizing the wear resistance and the mechanical properties of the aramid fiber.

Description

technical field [0001] The invention relates to a sports shoe sole and a preparation process thereof, in particular to a sports shoe sole with high wear resistance and a preparation process thereof. Background technique [0002] Sports shoe substrates are classified into the following categories: [0003] (1) Rubber: used for outsoles of various sports shoes; advantages: good wear resistance, non-slip, elastic, not easy to break, good softness, good extensibility, stable shrinkage, good hardness, and good bendability. Disadvantages: heavy weight, easy to spit frost (a quality problem), not easy to corrode (environmental protection problem) [0004] (2) PU: High molecular polyurethane synthetic material, often used in the midsole of basketball and tennis shoes, and can also be directly used in the outsole of casual shoes. Advantages: high density, high hardness, wear resistance, good elasticity, good oxidation resistance, easy to corrode, good for environmental protection, ...
