Problems solved by technology

The shock absorption performance of shoes mainly depends on the material and structure of the sole. At present, the structural shock absorption technology of sports shoes is relatively mature, such as Nike's "Zoom Air", "Max Air", Adidas' "ADIPRENE", "ADIPRENE+", " New structure shoes such as "torque bar" and Li Ning bow have come out one after another, while the material shock absorption research reports of sports shoes mainly focus on the foam midsole and insole of sports shoes, and there are few research reports on the shock absorption of the outsole.
[0003] In the 201010248174.1 patent, different ratios of butadiene rubber / bromobutyl rubber were used as the main components to prepare high shock absorption and wear-resistant rubber outsole materials, but the addition of a large amount of butadiene rubber reduced the loss of materials Factor, and the damping temperature range is narrow, so the shock absorption performance of the sole material is limited

Abstract

The invention relates to a wide-temperature domain high-shock absorbance sports footwear sole rubber material and its preparation method. The material is suitable for sports footwear soles with wide temperature domain requirement and high shock absorbance performance requirement. The wide-temperature domain high-shock absorbance sports footwear sole rubber material is composed of brominated butyl rubber, BR, a strengthening agent, a vulcanizing agent and a sulfuration promoter, and petroleum resin. The maximum loss factor value of the wide-temperature domain high-shock absorbance sports footwear sole rubber material is 0.34-0.45, the damping temperature domain (tan delta is greater than or equal to 0.2) is -44-53 DEG C, DIN abrasion is less than or equal to 100mm<3>. The material has the advantage for keeping good shock absorbance performance in wide temperature domain.

Description

(1) Technical field [0001] The invention relates to a rubber material for soles of sports shoes with wide temperature range and high shock absorption and a preparation method thereof. The material is suitable for middle and high-grade sports shoe soles with wide temperature range requirements and high shock absorption performance requirements. (2) Background technology [0002] With the continuous advancement of science and technology, the technological content of today's sports shoes is also increasing, and the development and application of shock absorption technology has attracted more attention. Good shock absorption performance can improve the wearing comfort of sports shoes, buffer the shock caused by the impact force on the body during exercise, and protect human bones and joints from damage. The shock absorption performance of shoes mainly depends on the material and structure of the sole. At present, the structural shock absorption technology of sports shoes is rela...
