Description

高弹性EVA材料及其生产方法
技术领域
本发明涉及一种高弹性EVA材料的生产方法。
背景技术
现有的鞋底材料存在弹性不佳的缺陷，需要进行改进。
发明内容
本发明的目的在于提供一种弹性好的高弹性EVA材料的生产方法。
本发明的技术解决方案是：
一种高弹性EVA材料，其特征是：由下列重量份的原料组成：
EVA8003         30份
EVA7350         50份
CaCO3           20份
发泡剂ACH         2~4份
架桥剂DCP         0.2~0.4份
氧化锌             1~2.5份。
一种高弹性EVA材料的生产方法，其特征是：包括下列步骤：
（1）利拿：将EVA8003、EVA7350、CaCO3、氧化锌混炼360″，然后加入发泡剂ACH、架桥剂DCP混炼60″后出料，冷却至120℃；
（2）薄通：将经步骤（1）处理的材料翻厚二次至7~8mm厚，然后打薄2~3次至0.7~1.0mm厚，再翻厚二次至7~8mm厚；
（3）出片：出片厚度1.3~1.5mm，出片温度为40℃；
（4）发泡架桥：在165±3℃、压力为150kg/cm2下处理1-2min；
（5）剖片：将经步骤（4）处理的材料剖切呈规定厚度的片材；
（6）裁断：分尺码进行裁断。
本发明工艺简单、易操作，产品弹性优异，反弹性55%↑。
下面结合实施例对本发明作进一步说明。
