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...
