Abstract

The invention discloses a damping cushion block. The damping cushion block comprises a shell and an inner core. The shell is provided with a cavity and wraps the inner core through the cavity. The density of the shell is 1.0-1.3 g / cm<3>, and the density of the inner core is 0.3-0.4 g / cm<3>. The shell with the density is high in hardness and strength, and the inner core with the density is high in elasticity and softness. The damping cushion block makes contact with the outside through the shell and absorbs pressure generated when a user moves and performs buffering through the inner core, so that a damping effect is achieved. The strength of the shell is high, so that the damping cushion block can resist damage of most hard substances and is quite limited in damage to shoes even if being pierced by sharp substances such as nails, and as the shell and the inner core are both solid, the use and damping function of the shoes cannot be affected.

Description

technical field [0001] The invention relates to the field of shoe sole design, in particular to a shock-absorbing pad and a preparation method thereof. Background technique [0002] The shoes with shock-absorbing function on the market today are usually equipped with air cushions on the soles of the shoes. The air cushions can absorb part of the pressure generated by the user's actions and play a cushioning effect, thereby achieving the purpose of shock absorption. But the strength of the air cushion of this shock-absorbing shoes is not high, and once the air cushion encounters a harder or sharp object, such as a nail, it is easily pierced, and once the air cushion is pierced, the gas in it will be discharged, thereby If the damage is difficult to repair, not only the shoes will lose the shock absorption function, but also their appearance and normal use will be greatly affected, and the reliability and practicability will be low. Contents of the invention [0003] The ob...
