Abstract

The invention discloses a rubber material for soles. The rubber material is prepared from the following components in parts by weight: 30 to 70 parts of butadiene rubber, 10 to 30 parts of isoprene rubber, 10 to 30 parts of brominated butyl rubber, 15 to 40 parts of NBR (Nitrile Butadiene Rubber), 2.0 to 5.0 parts of polyethylene glycol, 0.5 to 2 parts of stearic acid, 2.0 to 5.0 parts of activated zinc oxide, 2.0 to 6.0 parts of homogenizing agent, 0.5 to 2 parts of active agent, 1.0 to 3.0 parts of anti-aging agent, 1.5 to 2.0 parts of vulcanizing agent, 1.6 to 2.1 parts of accelerator, 30 to 70 parts of white carbon black, 3 to 6.5 parts of plasticizer, 2.0 to 5.0 parts of softening oil, 0.5 to 1.0 part of paraffin, 2.0 to 5.0 parts of tackifier and 2.0 to 5.0 parts of abrasion-resistant agent. The invention discloses a preparation method of the rubber material. The rubber material for the soles, disclosed by the invention, has the advantages that excellent performance can be maintained under a low temperature, and non-slip performance that cannot be matched by common rubber soles is obtained.

Description

technical field [0001] The invention relates to a material for shoe soles, in particular to a rubber material for shoe soles and a preparation method thereof. Background technique [0002] Due to its special purpose, sports shoes require its sole rubber to have anti-slip performance and good cold resistance. However, the rubber used in the current sports shoe soles is mainly formulated with isobutylene-isoprene containing active bromine. Mainly copolymer elastomer, this kind of rubber sole is very unstable in the production process. Although the sole rubber has good performance in anti-slip performance, it has certain deficiencies in elasticity and anti-slip performance under cold conditions; The soles of sports shoes are easy to slip during bouncing and running under cold conditions, and the soles wear out quickly and lose their elasticity. Contents of the invention [0003] Aiming at the disadvantages, the present invention proposes a rubber material for shoe soles, whi...
