Description

抗菌鞋材及其制备方法
技术领域
本发明涉及鞋材制造材料，特别涉及一种抗菌鞋材及其制备方法。
背景技术
众所周知，鞋内的异味和有害菌类是一直以来困扰人们的问题。交期是由于身体的小汗腺分泌旺盛，汗腺分泌物在细菌、霉菌分解下产生秽臭。出汗促使细菌容易繁殖，因此脚臭常与出汗症伴发。脚气不仅严重影响患者日常的工作和生活，而且还极易传染给他人。为防患脚气，人们想出了很多办法，其中就有采用吸汗效果好的棉鞋垫，或用中药等药物处理过的鞋垫来改善鞋内环境，有的短期内效果理想，但在出汗多或长时间使用的情况下很难达到理想效果。
公开号为CN102504355A的中国专利公开了一种弹性抗菌除臭鞋材，其具有较多成分，因此导致成本较大，影响批量生产，因此有待改进。
发明内容
本发明的目的是提供一种抗菌鞋材，其具有抑制脚板菌类生长甚至杀死菌类的优点。
本发明的上述技术目的是通过以下技术方案得以实现的：
一种抗菌鞋材，按照重量份包括如下组分：载体50-60份、乙烯-乙酸乙烯共聚物50-70份、再生聚乙烯50-70份、发泡剂4-6份、交联剂0.1-1份、硬脂酸0.1-1份、氧化锌0.1-1份。
通过采用上述技术方案，利用氧化锌增强抗菌作用，而氧化锌和硬脂酸配合。硬脂酸在橡胶硫化中属于硫化活性剂。硬脂酸作活性剂时可以得到酸性活化作用，并能与金属氧化物形成可溶性盐，增加金属氧化物对促进剂的活化能力。硬脂酸是硬脂酸根和氢离子的来源，在硫化体系中起缓冲作用。在于氧化锌存在时，硬脂酸与氧化锌并用时起到的作用有提高交联密度，提高胶料的耐热性和耐老化性，活化硫化剂等作用。而氧化锌能够起到灭菌的作用。
本发明进一步设置为：所述载体按照重量份包括如下组分：磷酸锆42-52份。
通过采用上述技术方案，利用磷酸锆进一步增强抗菌效果。
本发明进一步设置为：所述载体按照重量份还包括有硝酸银∶氧化锌＝14-25∶2-3。
通过采用上述技术方案，银离子可以使细菌的蛋白质构象改变，最终导致细菌死亡。而在使用中发现银离子容易与人体表面的氯离子发生反应生成氯化银蓄积在人体的表面从而让人体的表面有银白色的粉末，对人体会造成损坏，甚至遇到过敏者将会有极大的危害。因此采用硝酸银，硝酸银呈弱酸性，根据平衡反应，硝酸银会产生硝酸，而硝酸能够抑制氯化银的产生。
本发明进一步设置为：所述发泡剂选取碳酸氢钠。
通过采用上述技术方案，碳酸氢钠具有便宜且发泡量大的优点，而碳酸氢钠产生的二氧化碳具有较强的热稳定性进而避免与其他物体发生反应。
本发明进一步设置为：所述交联剂选取双叔丁基过氧异丙基苯。
通过采用上述技术方案，利用双叔丁基过氧异丙基苯能够增强整体的强度和弹性。
本发明的另一个目的是提供一种抗菌鞋材的制备方法，包括如下步骤：
步骤1：按照重量份称取，乙烯-乙酸乙烯共聚物50-70份、再生聚乙烯50-70份、发泡剂4-6份、交联剂0.1-1份、硬脂酸0.1-1份、氧化锌0.1-1份、磷酸锆42-52份、硝酸银14-25份、氧化锌2-3份，将上述组分放入封闭式密炼机中并在120-130℃和7-8公斤压强的条件下混炼20min；
步骤2：将步骤1中封闭式密炼机中的组分转移至开放式密炼机中进行3-4次翻料均匀，冷却至室温并挤入模具内，即得到初产品；
步骤3：让步骤2中的模具处于175-180公斤的油压压力下，并让温度保持在170-180℃之间持续2h，打开模具后，即得到抗菌鞋材。
通过采用上述技术方案，通过采用上述方法可以得到大量的抗菌鞋材。
综上所述，本发明具有以下有益效果：
1、本发明具有利用氧化锌增强抗菌作用，而氧化锌和硬脂酸配合。硬脂酸在橡胶硫化中属于硫化活性剂。硬脂酸作活性剂时可以得到酸性活化作用，并能与金属氧化物形成可溶性盐，增加金属氧化物对促进剂的活化能力。硬脂酸是硬脂酸根和氢离子的来源，在硫化体系中起缓冲作用。在于氧化锌存在时，硬脂酸与氧化锌并用时起到的作用有提高交联密度，提高胶料的耐热性和耐老化性，活化硫化剂等作用。而氧化锌能够起到灭菌的作用。
2、本发明中的银离子可以使细菌的蛋白质构象改变，最终导致细菌死亡。而在使用中发现银离子容易与人体表面的氯离子发生反应生成氯化银蓄积在人体的表面从而让人体的表面有银白色的粉末，对人体会造成损坏，甚至遇到过敏者将会有极大的危害。因此采用硝酸银，硝酸银呈弱酸性，根据平衡反应，硝酸银会产生硝酸，而硝酸能够抑制氯化银的产生。

对比例1：
与实施例2不同之处在于，去除氧化锌，其他与实施例2相同。
对比例2：
与实施例2不同之处在于，去除硬脂酸，其他与实施例2相同。
测试实验1：
按照相同的重量份称取实施例1、实施例2和实施例3。
称取琼脂粉末75g、牛肉膏1.5g、蛋白胨5g，氯化钠2.5g于500ml烧杯中，并向烧杯中加入约250ml纯净水，放到电炉上加热融化，然后分装于锥形瓶，置121℃，103.4kPa的条件下灭菌持续20min。冷却至50℃后倒入14mm2的培养皿中，再冷却到25℃作为试验用培养基。按照上述方法制作A、B、C、D、E五个培养基。
在A、B、C、D、E五个培养基中的中央分别嵌入端面面积为4mm2的相同体积、重量的实施例1、实施例2、实施例3、对比例1和对比例2。
待琼脂凝固后，无菌操作注入1000μL菌液于培养基上，涂抹均匀。在37℃的条件下培养24h。这个过程中A、B、C、D、E五个培养基中，实施例1、实施例2、实施例3、对比例1和对比例2的上方形成一个抑菌环，期间不断测量抑菌环的大小。得到抑菌环直径的变化，得到表1。
表1：A、B、C三个培养基中抑菌环的直径变化关系
以抑菌环直径大小作为评价材料抗菌性能的依据，抑菌环越大，抑菌效果越好。
从表1中分析可以得到，锌能够增强银的抗菌强度。实施例1、实施例2和实施例3中的银和锌的质量比逐渐增大，相应地但是抑菌环的直径并没有随之增大，而是B培养基中的抑菌效果最好。经过试验得到银和锌的质量比为6.1时，培养基的抑菌效果最好。通过A培养基和D培养基的比较发现，虽然D培养基中的银含量增加了，但是D培养基的抑菌效果与A培养基的抑菌效果相差不大，A培养基中的银和锌含量的重量小于D培养基中银含量的重量。A培养基和D培养基的比较可以得知A培养基中的银和锌是通过硬脂酸起到了协同作用。
