Description

Technical Field

[0002] A supercritical midsole is a green polymer microporous material prepared by replacing organic foaming agents with supercritical carbon dioxide or nitrogen. This material has dense and uniform pores, a small specific gravity, and more excellent mechanical properties. It is widely used in fields such as national defense, aerospace, energy, transportation, construction, packaging, and sports equipment. As a lightweight and high-performance material, the functions of the midsole in shoes mainly include providing stability, cushioning, and rebound, absorbing the impact force generated during exercise, protecting the feet, and providing a comfortable foot feeling.

[0003] For this reason, Chinese Patent Application No. CN216165580U discloses an RB rubber foam shoe midsole with an airbag. A cavity is opened at the heel of the midsole body, and an airbag is installed in the cavity. A nylon outer sheath is arranged on the outer surface of the airbag. One end of the airbag is provided with a valve core, and the end of the valve core is located in a groove opened on the outer surface of the midsole body. A buffer groove is arranged on the upper surface of the airbag, and a pulling elastic cord is adhesively fixed on the inner surface of the airbag. Through the airbag installed in the cavity opened at the rear heel of the midsole body, it is convenient to adjust the elastic strength of the midsole after the airbag is inflated through the valve core. At the same time, the nylon outer sheath arranged outside the airbag is convenient for the nylon outer sheath to protect the airbag and prevent the airbag from over-inflating due to excessive inflation, thereby improving the safety of the airbag. At the same time, the buffer groove arranged on the upper surface of the airbag and the pulling elastic cord adhesively fixed on the inner surface of the airbag are convenient for the pulling elastic cord to pull the airbag.
