Description

一种淀粉乙烯-醋酸乙烯酯复合发泡剂耐磨鞋底材料
技术领域
本发明涉及鞋底材料技术领域，尤其涉及一种淀粉乙烯-醋酸乙烯酯复合发泡剂耐磨鞋底材料。
背景技术
鞋底的构造相当复杂，就广义而言，可包括外底、中底与鞋跟等所有构成底部的材料。依狭义来说，则仅指外底而言，一般鞋底材料共通的特性应具备耐磨、耐水，耐油、耐热、耐压、耐冲击、弹性好、容易适合脚型、定型后不易变型、保温、易吸收湿气等，同时更要配合中底，在走路换脚时有刹车作用不致于滑倒及易于停步等各项条件。鞋底用料的种类很多，可分为天然类底料和合成类底料两种。天然类底料包括天然底革、竹、木材等，合成类底料包括橡胶、塑料、橡塑合用材料、再生革、弹性硬纸板等。
由于材料的发展，鞋子的使用寿命越来越长，如何保证鞋底耐磨，不变形，是本领域面临的技术难题之一。现有技术一般是在鞋底材料中加入各种金属合金，然后在硫化工艺中掺杂加入耐磨合金颗粒。合金颗粒虽然增加鞋底的耐磨性能，但其重量较大，与鞋子轻量化的目标相违背，因此其应用受到较大的限制。
发明内容
本发明的目的在于提出一种淀粉乙烯-醋酸乙烯酯复合发泡剂耐磨鞋底材料，能够提高材料的性能，能够增加耐磨性能的同时，提升轻量化。
为达此目的，本发明采用以下技术方案：
一种淀粉乙烯-醋酸乙烯酯复合发泡剂耐磨鞋底材料，按重量份计包括
乙烯-醋酸乙烯酯 100
淀粉 30-50
聚酰亚胺树脂 10-30
乙烯-丙烯酸共聚物 10-30
石墨烯纤维 5-10
无机填料 0-30
甘油增塑剂 4-12
碳化钨-钴硬质合金颗粒 2-5。
本发明采用部分淀粉部分替换掉原先的乙烯-醋酸乙烯酯，增加了其生物降解能力，利于保护环境，同时又减少了成本。
但由于淀粉的物理性质会导致鞋底材料的性能下降，因此本发明必须将石墨烯纤维加入，与淀粉协同使用，来增加其拉伸强度和撕裂强度。同时，由于掺杂了石墨烯和碳化钨-钴硬质合金颗粒，因此其耐磨性得到提高，轻量化也得以实现。
本发明所述的鞋底材料，在制备成鞋底之后，其密度最小为0.099-0.114g/cm3，拉伸强度达到24kg/cm2，回弹性超过54％，撕裂强度超过27kg/cm。
