[0079] In the above-mentioned embodiment, the formula of scheme 1 is produced according to the following process:
[0080] Step 1: Pour EVA, polyethylene oxide, filler, natural particles, zinc oxide, stearic acid, degradation agent into the blender, stir and heat, first heat to 90-91°C to melt the material, and then increase the temperature to 119°C-120°C, then add bridging agent and foaming agent, then raise the temperature to 133°C-134°C, and pour the materials into the internal mixer;
[0081] Step 2: Banbury the materials in a banbury mixer, the banbury time is 12 minutes, and the temperature is 120-121°C;
[0082] Step 3: Pour the mixed material into the open mixer, lower the temperature to 75...
