EVA damping element and shoe sole with the same

Abstract

The invention discloses an EVA damping element capable of effectively integrating EVA waste heads, effectively and completely developing performance characteristics of the EVA waste heads and realizing the effective secondary recovery of the EVA waste heads, and a shoe sole with the damping element. The EVA damping element comprises an element body with a filling groove, gel medium is fully filled in the filling groove, and EVA waste head particles are distributed in the gel medium; the EVA waste head particles are obtained through cutting up the EVA waste heads, and the maximum radial dimension of the EVA waste head particles is smaller than the groove depth of the filling groove; a sealing plate covers the notch of the filling groove of the element body, and the sealing plate enables the filling groove to form a closed space.

Description

technical field [0001] The invention relates to an EVA damping element and a shoe sole with the damping element. Background technique [0002] Shoes are indispensable daily necessities in people's daily life, and sole is an important part of shoes. The sole in the prior art generally comprises big bottom and midsole, and the big bottom of shoes generally adopts the better rubber material of abrasion resistance, and in order to increase the elasticity and comfort of shoes, the midsole of shoes generally adopts comparatively soft EVA material, In the process of using EVA to make the midsole, it is necessary to remove the burrs on the midsole. In this process, a large number of EVA waste heads will be generated. These EVA waste heads are basically strip structures with a diameter of 1-2cm, which are very small and scattered and cannot be used. The EVA waste heads are reprocessed into other products, and these EVA waste heads have also been vulcanized and cross-linked. The EVA ...

Problems solved by technology

The sole in the prior art generally comprises big bottom and midsole, and the big bottom of shoes generally adopts the better rubber material of abrasion resistance, and in order to increase the elasticity and comfort of shoes, the midsole of shoes generally adopts comparatively soft EVA material, In the process of using EVA to make the midsole, it is necessary to remove the burrs on the midsole. In this process, a large number of EVA waste heads will be generated. These EVA waste heads are basically strip structures with a diameter of 1-2cm, which are very small and scattered and cannot be used. The EVA waste heads are reprocessed into other products, and these EVA waste heads have also been vulcanized and cross-linked. The EVA waste heads can no longer be integrated and processed, and cannot be recycled. A large number of EVA waste heads that cannot be recycled will cause Serious environmental pollution and waste of resources

At present, in order to solve the environmental pollution and resource waste problems caused by EVA waste heads, the existing EVA waste heads are collected and recycled, and the EVA waste heads are ground into powder, which is used as a filler and added to the production of some EVA products. The powdered EVA waste head has lost its original elastic properties and other characteristics, and it is used as a filler only to reduce costs and to prepare some products with low price and low performance requirements. The EVA waste head has not really been fundamentally obtained. Effective utilization has not realized the effective utilization of resources in the true sense. Therefore, how to fully and effectively utilize the performance characteristics of the EVA waste head to achieve effective resource recycling and realize the real secondary recycling of the EVA waste head is the current issue. important issues to be addressed
