Description

一种抗菌耐磨环保瑜伽砖及其制备工艺
技术领域
本发明涉及瑜伽用品技术领域，特别涉及一种抗菌耐磨环保瑜伽砖及其制备工艺。
背景技术
瑜伽砖是为初级者瑜伽练习者与柔韧性差的练习者提供的一种辅助工具，帮助调整姿势，辅助身体达到一些动作。
瑜伽砖是为瑜伽练习者练习的一种辅助工具，能帮助调整姿势、从而完成有一定难度的瑜伽动作。瑜伽砖可以帮助我们支撑身体的不同部位，避免初学者因为柔软度不好或肌力不够而造成身体其他部位的紧张。如果自身柔韧性差，练习一段时间后发现部分动作难以完成，也可以借助瑜伽砖。在练习时，瑜伽砖可以帮助支撑身体的不同部位，防止练习时拉伤，但并不是练习所有动作都需要用到瑜伽砖的。当自身无法完成动作，或者需要瑜伽砖来过渡时，才需要用到瑜伽砖。另外，部分体式的练习本身就需要用到瑜伽砖，如前曲式、半月式等。使用瑜伽砖，能降低动作的难度，帮助伸展筋骨，帮助动作做到位，进而强化塑身效果。
瑜伽砖通常由两种材质制成，一种是EVA，另一种是软木。EVA制成的瑜伽砖采用密封发泡结构，弹性好，防滑性好，即使承受一辆汽车重压也不会变形。而软木制成的瑜伽砖手感很好，功能也不错，适合瑜伽爱好者选购。因此，瑜伽砖需要在弹性，手感、防滑性以及吸水性方面具有较好的性能。如果单纯采用软木制作瑜伽砖，完全无法满足需要。
EVA新型环保塑料材料，具有良好的缓冲、抗震、隔热、防潮、抗化验学腐蚀等优点，具无毒、不吸水。EVA制品防震性能优异，但是，EVA发泡率高时，材料变形大，力学性能显著下降，且仍存在耐磨性、黏合性以及与其他物质的相容性较差等缺陷。当采用单纯的EVA制作瑜伽砖时，首先，由于其容易导致局部变形使得手感较差，使用效果不佳；第二，由于其较差的吸水性能，当使用者出汗时，容易造成摩擦力降低，导致使用体验变差；第三，耐磨性较差，使用寿命较短，第四，改进吸汗后，容易造成细菌滋生的问题。
发明内容
本发明的目的在于解决目前瑜伽砖所存在的上述问题，提供一种新的瑜伽砖，该瑜伽砖采用聚烯烃弹性体（POE）包覆EVA，形成两层结构，通过POE作为表层改善EVA存在的上述问题，由于POE相对EVA容易改进，特采用POE外层包覆EVA内层。同时还提供了相应瑜伽砖的制备工艺。通过该工艺，制备了一种新式的瑜伽砖。所制备的瑜伽砖不仅具备EVA的防震性能，同时，能够提供手感和耐磨性，从而提高其使用寿命。并且利用其较高的吸水性避免使用者出汗后的防滑性能下降问题的发生。同时，也在抗菌问题上进行了相应的处理。
本发明解决其技术问题所采用的技术方案是：
一种抗菌耐磨环保瑜伽砖，所述瑜伽砖采用POE发泡材料层包覆EVA发泡材料层制备而成；
所述EVA发泡材料的原料按重量份数计至少包括以下组分：EVA60-70份，PVA5-8份，轻质碳酸钙3-8份，AC发泡剂1-3份、氧化锌1-2份、交联剂2-3份；
所述POE发泡材料的原料按重量份数计至少包括以下组分：POE80-90份，超支化聚乙烯10-15份，多孔抗菌材料3-5份、增强剂3-5份，有机增韧剂丝素蛋白1-3份、氧化锌1-2份、交联剂2-3份，有机硅弹性体2-4份。
作为优选，所述多孔抗菌材料为牛煅烧松质骨抗菌材料。
作为优选，所述牛煅烧松质骨抗菌材料的制备方法包括以下步骤：将牛骨松质骨切割成骨条，然后在沸水下蒸煮40-60分钟，去除有机质；然后取出沥干，烘干后，在1000-1200℃下煅烧2-3h得到牛煅烧松质骨，将牛煅烧松质骨与银源制备凝胶，得到牛煅烧松质骨凝胶材料，然后将牛煅烧松质骨凝胶材料进行水热碳化反应，得到牛煅烧松质骨抗菌材料。
本申请采用了牛煅烧松质骨抗菌材料，经过碳化后的材料具有多孔的特性，在负载阴离子后，从而达到抗菌的效果。多孔的结构，使得制备的POE材料具有较好的吸水性，另一方面，从而使得制备的POE材料在后期能够比较容易降解，从环保角度来讲，具有一定的意义。
作为优选，所述银源为纳米氧化银。
作为优选，所述超支化聚乙烯为线性无规超支化聚乙烯。
作为优选，所述超支化聚乙烯的重均分子量为320kg/mol，分子量分布指数为2.15，总支链数为105/1000C。
作为优选，所述有机增韧剂为丝素蛋白。
作为优选，所述交联剂为DCP。
一种抗菌耐磨环保瑜伽砖的制备工艺，包括以下步骤：
（1）EVA板材的制备，按照EVA的预定配比进行发泡工艺；
（2）POE板材的制备：按照POE的预定配比进行发泡工艺；
（3）按照预定尺寸将EVA板材和POE板材切割成相应的尺寸；
（4）将POE板材在冷压机上加热、成型、冲压；并涂覆背胶；
（5）在EVA上涂覆胶水，然后与POE贴合；
（6）清理干净并包装。
本发明的有益效果是：制备的瑜伽利用改性的POE材料作为其表层，从而使得制备得到的瑜伽砖具有较好的抗菌性能，并且其耐磨性能较佳；通过测试其吸水性能较好，能够吸收使用者在一定时间内所排出的汗液，同时利用其抗菌性能，避免了吸收汗液后发臭。
