Abstract

The invention discloses a sneaker sole material with high wear resistance and low hardness and a preparation method thereof, particularly a method for preparing a sneaker sole material which is suitable for middle and high-grade sneaker soles with higher requirements on wear resistance and comfort. The sneaker sole material comprises the following components: butadiene rubber (BR), natural rubber (NR), styrene butadiene rubber (SBR), softening oil, a reinforcing agent, an activating agent, a coupling agent, a vulcanizer, a vulcanization accelerator, a tackifier and an anti-aging agent. A series of sole material with high wear resistance (DIN abrasion is less than or equal to 40mm<3>, and the length of grinding marks is 3.0 to 4.0mm) and low hardness (ShoreA 60-66) is prepared by screening the proportion of rubber composition, the coupling agent, the accelerator, and the activating agent and reasonably controlling a process on the basis of the rubber, the softening oil and the reinforcing agent. The material has the advantages that: (1) the total weight of a sneaker sole is expected to be reduced, namely the thickness of a rubber outer sole of a sneaker can be reduced under the condition that the material has the wearing life which is the same as that of the conventional sneaker sole, so that the total weight of the sole is reduced; (2) the humidity and slip resistance is improved, namely the hardness of the sole is lower and the sole is easy to distort under the condition of stress, so that the contact area of the sole and the ground is increased, and the aim of improving the humidity and slip resistance of the sole is fulfilled; and (3) the comfort is improved.

Description

(1) Technical field [0001] The invention relates to a rubber sole material and a manufacturing method thereof, in particular to a sports shoe sole material with high wear resistance and low hardness and a manufacturing method thereof. This material is suitable for the soles of mid-to-high-end sports shoes with high requirements for wear resistance and comfort. (2) Background technology [0002] With the development of science and technology and the progress of society, people's living standards continue to improve. Improving the quality and performance of all kinds of shoes and making the wearer safer and more comfortable is the ultimate goal and direction of the development of the entire shoe industry. According to reports in the literature, for every 100 grams of shoe weight, the wearer's physical consumption will increase by 1%. In order to reduce physical energy consumption and improve wearing comfort, lightweight, high-performance shoe materials have become the main directi...
