发泡剂3份；
偶联剂0.4份；
锌氧粉1份；
硬脂酸0.5份。
本发明所述的轻质EVA鞋底材料的制备方法包括以下步骤：
①密炼：将各组分按重量份配好送入密炼机密炼，密炼机温度控制在90~100℃，气压在0.7~0.8kg，密炼时间5~9分钟；
②开炼：将步骤①处理后的材料送入开炼机开炼，开炼温度在75~85℃，15mm2次，1mm2次；
③造粒：将上述处理后得到的材料造粒，造粒温度75~80℃；
④冷却：造粒完成后冷却6小时；
⑤发泡：冷却完成后将材料发泡，发泡机温度在165~170℃，压力160~180kg，发泡时间5-9分钟。
有益效果：本发明所述鞋底材料既具备了EVA发泡材料制成的鞋底本身的舒适性和弹性，同时在EVA底料中加入轻质料、轻粉等添加剂发泡，可以有效的减轻材料自身重量，使穿着时更加的轻便。
