Description
Technical Field
The invention belongs to the field of shoe materials, and particularly relates to a light high-elastic compression-resistant shoe foam material.
Background
In order to reduce physical energy consumption and improve wearing comfort, lightweight high-elasticity foam materials have become a main direction for developing sports shoe materials. With the improvement of living standard, sports fitness becomes a common consensus, and therefore, the requirements on the light weight, the elasticity and the comfort of the sole material of the shoes, especially the sports shoes, are higher and higher. Light weight and high elasticity are the main characteristics of sports shoe materials, and especially professional sports such as basketball and running have high requirements on the weight and the rebound resilience of soles.
In recent years, a supercritical foaming process is adopted, and high-performance thermoplastic elastomers such as Polyamide Elastomers (PEBA), polyurethane elastomers (TPU), polyether ester elastomers (TPEE) and the like are used for preparing light high-elastic high-performance sports shoe midsoles, which occupy the main share of high-end sports shoes.
The thermoplastic elastomer contains hard segments and soft segments with different molecular structures in a polymer chain structure, and at room temperature, as the material is between the glass transition temperatures of the soft segments and the soft segments, the hard segment micro-regions are in a glass state and serve as physical cross-linking points, the thermoplastic elastomer is endowed with certain strength, and the soft segment micro-regions are in a high-elasticity state, so that the material is endowed with good ductility and elasticity. Because the hard segment part is similar to the characteristics of thermoplastic plastics, the physical crosslinking effect of the hard segment part is melted and crystallized along with the change of temperature and is reversibly changed.
After the thermoplastic elastomer material is foamed, a porous material with lighter weight and better elasticity is obtained, and the porous material can obtain excellent service performance when being used in the shoe insole. For example, a midsole made of expanded thermoplastic polyurethane elastomer beads developed by Adidas and Pasteur has a thickness of 0.22 to 0.26g/cm3The density of the shoe sole is more than 65 percent, and the shoe sole becomes a novel shoe material with revolutionary significance.
In recent years, Atoma corporation has been used for Nake and Lining sports at home and abroad
The polyamide elastomer is used for preparing a novel high-performance midsole by adopting a supercritical foaming technology, and the density of a finished sole product is as low as 0.10-0.18g/cm3The resilience performance of the marker post can reach over 75 percent, and the marker post becomes a new marker post in the field of shoe materials. However, the above materials need to be formed by supercritical foaming process, which is relatively complex and difficult to operate.
For the light high-elastic mid-sole prepared by the common chemical foaming process, the light high-elastic mid-sole is generally obtained by taking ethylene-vinyl acetate resin (EVA) as a matrix and mixing with one or more copolymers, but the density is generally 0.20-0.26g/cm3The resilience is less than 65 percent, the durability is poor, a plurality of folds appear on the side wall of the sole after the shoe is worn for a period of time, the foot feeling is obviously reduced, and the hardness is obviously improved.
Therefore, the development of insole materials with relatively simple process and the characteristics of light weight, high elasticity, low compression set rate and the like becomes a direction for breaking through sports shoe materials.
