Abstract

The invention relates to a lightweight anti-fatigue PEBA sole, the main components are PEBA material particles, modified PEBA particles, talcum powder, zinc stearate and an anti-wear agent, and the modified PEBA particles are formed by extruding and foaming the following components in parts by weight: 80-100 parts of PEBA, 5-10 parts of SF-GNRs, 3-5 parts of modified glass fiber, 3-8 parts of supercritical fluid and a proper amount of graphene dispersion liquid. A plurality of PEBA primary particles are wrapped in each modified PEBA particle, graphene sheets are wrapped outside the modified PEBA particles, modified glass fibers and SF-GNRs are uniformly dispersed in each PEBA primary particle, the graphene sheets are clamped among the PEBA primary particles, the modified PEBA particles are dispersed in a PEBA material rice continuous phase during injection molding, and the graphene sheets are stored on interfaces of the modified PEBA particles. Therefore, the prepared PEBA sole has low density, high rigidity and excellent anti-fatigue and anti-impact strength while the thickness of the sole is reduced.

Description

technical field [0001] The invention belongs to the technical field of shoe materials, and in particular relates to a lightweight anti-fatigue PEBA shoe sole and a molding process thereof. Background technique [0002] Acceleration has a decisive influence on an athlete's performance in many competitions. In sprinting, for example, victory or defeat depends not only on the ultimate attainable speed, but also on how quickly this speed is achieved. Even more important is acceleration during movements with frequent changes of direction. Especially for football, but also for other field games, there is always an acceleration process when a change of direction of running or a sudden jump is required. [0003] According to the laws of physics, the achievable acceleration directly depends on the mass of the object to be moved. Therefore, an important aim in the design of sports shoes, in particular football boots, is to reduce the overall mass as much as possible in order to inc...
