Hard high-damping foamed rubber sole and preparation method thereof

Abstract

The present invention discloses a hard high-damping foamed rubber sole and a preparation method thereof. The hard high-damping foamed rubber sole is prepared from the following raw materials in partsby weight: 60-90 parts of natural rubber, 10-40 parts of chloroprene rubber, 3-7 parts of active zinc oxide, 1-3 parts of magnesium oxide, 1-3 parts of stearic acid, 0.5-1 part of anti-aging agent I,1-2 parts of anti-aging agent II, 5-8 parts of terpene resin, 6-15 parts of black factice, 15-25 parts of naphthenic oil, 20-40 parts of carbon black, 1-3 parts of urea, 1-3 parts of foaming agent I,1-3 parts of foaming agent II, 3-5 parts of physical foaming agent, 1-2 parts of accelerant I, 0.1-0.5 part of accelerant II, and 1-3 parts of sulfur. Compared with the prior art, the hard high-damping foamed rubber sole is characterized in that two closed-pore foaming agents, namely a foaming agent AC and a foaming agent OBSH, are synergized with the physical foaming agent, allowing the foamed rubber sole to have the advantages of light weight, low density, high comfort degree, and obvious damping effect; and meanwhile, the advantages of corrosion resistance and good anti-aging performance ofthe rubber are also maintained.

Description

technical field [0001] The invention belongs to the technical field of foamed rubber sole materials, and in particular relates to a hard and highly shock-absorbing foamed rubber sole and a preparation method thereof. Background technique [0002] With the continuous development of society, today's shoe material technology is also constantly developing and improving. The functionality of the sole directly restricts the quality of shoes and boots. The sole material of light weight, comfort, high elasticity and obvious shock absorption effect has become the current shoe The main direction of material development. [0003] In the past manufacturing of shoe materials, foam material soles are usually used. Although the soles made of this material are soft and comfortable, they have poor elasticity, weak shock absorption effect, and serious deformation, which cannot effectively support the weight of the human body for a long time, resulting in long service life. very short.

Problems solved by technology

[0003] In the past manufacturing of shoe materials, foam material soles are usually used. Although the soles made of this material are soft and comfortable, they have poor elasticity, weak shock absorption effect, and serious deformation, which cannot effectively support the weight of the human body for a long time, resulting in long service life. very short

However, although the commonly used rubber outsole material has good wear resistance, it has poor elasticity and weak shock absorption effect. The pressure point exerted by the human body on the sole will quickly transfer to the entire sole of the foot, and the impact force on the sole of the foot will be several times its own weight
