Foaming rubber composition for sole and application thereof

Abstract

The invention discloses a foaming rubber composition for a sole and application thereof. The foaming rubber composition for the sole comprises the following components in parts by weight: 40 to 60 parts of butadiene rubber, 10 to 35 parts of butadiene styrene rubber, 10 to 35 parts of artificial natural rubber, 10 to 40 parts of HS-860 rubber, 10 to 35 parts of EVA7350, 20 to 30 parts of white carbon black, 0.5 to 1 part of stearic acid, 5 to 8 parts of A-grade zinc oxide, 3.0 to 4.5 parts of PEG4000, 0.5 to 2 parts of an S683 anti-ageing agent, 0.5 to 2 parts of an S6064 anti-ageing agent, 1.5 to 2.5 parts of an A-08 protective agent, 1 to 2 parts of an SI-669 coupling agent, 1 to 2 parts of a DM accelerant, 4 to 5 parts of an ACP-H2 foaming agent, 1.5 to 2.5 parts of sulfur S-8 and a proper amount of a coloring agent. The traditional wear-resistant agent is not added into the sole which is prepared by the foaming rubber composition for the sole, so high cushioning performance and wear resistance still can be achieved while the lightweight effect that the specific gravity is only 1.18+/-0.02, and the resilience property is high.

Description

technical field [0001] The invention belongs to the technical field of materials for sports shoe soles, and in particular relates to a foam rubber composition for shoe soles and an application thereof. Background technique [0002] With the rapid development of the sports shoes market, people have higher and higher requirements for the wearing experience and appearance of the sole and other parts. For the sole material of sports shoes, not only must it have excellent support to meet the design requirements of special structures such as hollowing out, It also needs to have high cushioning, high elasticity, wear resistance and other functions. [0003] As the sole material of sports shoes, the traditional EVA foam material can meet common wear-resistant requirements by adding a certain amount of wear-resistant agent, such as CN105585769A discloses a high-wear-resistant elastic foamed rubber material and a preparation method thereof. The foam rubber material is composed of rub...

AI Technical Summary

Problems solved by technology

However, this kind of sole material generally has high hardness, poor cushioning, rebound performance, and poor fatigue resistance. After wearing for a period of time, there will be problems such as poor recovery such as collapse, and the sole will quickly lose elasticity. , the cushioning performance becomes poor, and for some special structures such as hollowing out, the sports sole of this material will also collapse and deform, seriously affecting the wearing experience and appearance structure of the shoes
