Description

一种用于鞋底的防水减震材料的制备方法
技术领域
本发明涉及复合材料技术领域，具体涉及一种用于鞋底的防水减震材料的制备方法。
背景技术
随着材料技术的不断发展，鞋底材料也不断在迭代，人们对鞋底材料的要求也越来越高，要求鞋底材料具备耐磨、耐水，耐油、耐热、重量轻、耐冲击、弹性好、定型后不易变型、保温、易吸收湿气等特征，但在现实的鞋底材料研发过程中，往往很难兼顾所有的特征，在解决了耐磨、耐热、耐油耐冲击和保温等问题时，往往防水、弹性好、重量轻等特征会被弱化。因此在鞋子领域的各大企业或公司，通常采用对鞋底进行额外的结构设计来均衡各个性能，比如设计空气垫、具有减震功能的蜂巢结构、中空橡胶球结构、拱形结构等。
被誉为“第五大塑料”的聚氨酯高分子材料，被广泛的用于高档皮鞋、运动鞋、旅游鞋等，由聚氨酯高分子材料制成的鞋底具有密度低，质地柔软、耐磨抗氧化、良好的保温性能和弹性性能，具有良好的减震作用。但是，该鞋底材料吸水性较强、鞋底易腐烂、易断裂透气性差等缺点。
在实现鞋底的耐磨性、耐热性、保温、不易变形的基本特征时，如果不依托鞋底的结构设计来实现鞋底良好的减震性能的同时，还要使聚氨酯鞋底具备良好的防水减震性能，那么就必须从鞋底材料本身进行改进。
发明内容
本发明提供一种用于鞋底的防水减震材料，以解决聚氨酯鞋底具有良好的减震性能而防水性能差的技术问题，改进后的聚氨酯鞋底材料具有良好的防水减震性能。
为解决上述问题，本发明采用的技术方案如下：

本发明对上述技术方案所述溴化丁基橡胶、氧化锌粉末、低密度聚乙烯、高密度聚乙烯、乙烯-醋酸乙烯共聚物、纳米碳酸钙、氢化苯乙烯弹性体、硬脂酸、硬脂酸锌、交联剂、发泡剂、阻燃剂、软化增塑剂、硅烷偶联剂、增韧剂、石墨、氧化镁、硅酸钙、偶氮二甲酰胺、聚乙烯改性材料的来源没有任何特殊要求，采用本领域技术人员所熟知上述技术方案所述原料的市售产品即可。
本发明所述的防水减震材料，它的制备方法包含如下步骤：
一级混炼：将20～40份乙烯-醋酸乙烯共聚物、2～5份纳米碳酸钙、5～10份氢化苯乙烯弹性体、0.3～0.5份硬脂酸、5～10份溴化丁基橡胶、0.4～0.8份氧化锌粉末、0.5～1份硬脂酸锌的混合物进行第一次混炼，得到一级混炼物料颗粒。

全混混炼：将所述发泡材料和40～50份聚乙烯改性材料进行全混混炼，在温度为160-180℃、压力为40-50MPa下密炼成型，得到防水减震材料。
所述聚乙烯改性材料由30-50份聚乙烯、10-40份锌氧粉、8-25份氧化镁、10-15份玻璃纤维、过氧化二0.8-1.5份异苯丙交联剂、1-2份硬脂酸活性润滑剂混炼制得。
由于采用了上述技术方案，本发明的有益效果是：采用上述原料和混炼方法获得的高分子聚合材料，具有耐磨性、耐热性、保温、不易变形的基本特征的同时，还具有优异的防水和减震特征，该材料应用于鞋底材料时，在没有附加减震结构设计时，仍然具有良好的防水减震性能。
