Abstract

The invention discloses a wear-resistant shoe sole material for a sneaker. The shoe sole material is mainly prepared from main materials, adhesives and plasticizer. The main materials are prepared from lithopone, argil, carbon black, activated zinc oxide, sulfur, stearic acid, nitrile rubber, collagenous fiber, activated zinc oxide, paroline, polyethylene glycol, light calcium carbonate and titanium powder. The hardness of the shoe sole material ranges from 65-70, the grinding crack length ranges from 4.5 mm to 5.0 mm, the DIN abrasion ranges from 50 mm<3> to 100 mm<3>, the elongation at break of the shoe sole material ranges from 660% to 700%, the tensile strength ranges from 15 MPa to 20 MPa, the right-angle tear strength ranges from 55 N / mm to 60 N / mm, the thickness of the shoe sole material ranges from 1.5 cm to 2 cm, and the density ranges from 1.25 g / cm<3> to 1.50 g / cm<3>. The shoe sole material has super wear resistant performance, has a good tensile property, and is durable in use, high in comfort degree, low in density and convenient to use.

Description

Technical field [0001] The invention belongs to the field of sports shoe material manufacturing, and specifically relates to a wear-resistant sole material of sports shoes. Background technique [0002] China's footwear industry has sprung up. In just over a decade, it has become the world's largest footwear producer and exporter. Especially after China's accession to the WTO, China's footwear industry has shown a strong development trend, and the output of the footwear industry has accounted for the world. The total amount is nearly 40%~50%. In the global footwear trade, my country's footwear exports have also accounted for 25%, and both of them rank first in the world. At present, my country's shoe consumption accounts for 22% of the world's total consumption, and it is one of the most important leather shoe consumers in the world. In the new century, with the continuous development of high technology, the demand for wear resistance of shoe materials is also increasing. [0003]...
