本发明涉及一种阻燃棉及其制备方法和应用，特别涉及一种负离子石墨烯远红外阻燃棉及其制备方法和应用。
背景技术
阻燃棉是棉经过特殊工艺加工后，具有一定的防火作用，不易燃烧，且离开火源后自动熄灭，不会再复燃的一种新型防火材料。随着阻燃棉的发展以及对防火的需求，阻燃棉的需求越来越大。但是，在使用的过程中发现，现有的阻燃棉有如下缺点：1、现有的阻燃棉的制备工艺是在制备好的棉的基础上，通过喷涂阻燃剂来达到阻燃的效果。阻燃剂都是一些化学合成的制剂，长时间使用会对人体产生一定的危害。并且，随着阻燃棉使用时间的加长，阻燃棉外层的阻燃剂涂层会逐渐磨损，影响阻燃的效果。2、现有的阻燃棉功能单一，不能满足消费者对棉制品需求。
硅藻泥产品具备独特的“分子筛”结构，其具有极强的物理吸附性和离子交换功能，可以有效去除空气中的游离甲醛、苯、氨等有害物质及因宠物、吸烟、垃圾所产生的气味，可以起到净化室内空气的作用。硅藻泥是由无机材料组成，因此不燃烧，即使发生火灾，也不会冒出任何对人体有害的烟雾。当温度上升至摄氏1300℃时，硅藻泥只是出现熔融状态，不会产生有害气体等烟雾。随着不同季节及早晚环境空气温度的变化，硅藻泥可以吸收或释放水分，自动调节室内空气湿度，使之达到相对平衡。尤其是沿海城市和南方空气较湿润的城市，调节室内空气湿度效果明显，减少潮湿的空气带来的烦恼。硅藻泥的主要成分硅藻土的热传导率很低，本身是理想的保温隔热材料，具有非常好的保温隔热性能，其隔热效果是同等厚度水泥砂浆的6倍。硅藻泥独具的“分子筛”结构，在接触到空气中的水分后会产生“瀑布效应”，从而不断的释放出对人体有益的负氧离子。
远红外线能够深入人体的皮肤以及皮下组织，从而促进血液循环，让身体保持一定的温度。除此之外，远红外线也是一种电磁波，所以人体能够迅速的吸收这种电磁波，深入到人体内的电磁波能够引起原子和分子的振动，通过共鸣吸收，形成热反应促使皮下深层温度上升，微细血管扩张促使血液循环，将淤血等妨害新陈代谢的障碍全部清除干净，重新使组织复活，促进酵素生长。
石墨烯具有诸多引人瞩目的光学属性，近年来IBM的研究人员已发现，石墨烯能吸收和辐射高达40％的远红外线。人体也是一个天然的红外线辐射源，其辐射频带很宽，无论肤色如何，活体皮肤的发射率为98％。人体同时又是良好的远红外线吸收体，其吸收波段以3-15微米为主，刚好是在石墨烯远红外线的作用波段。人体远红外线的吸收机制是通过人体组织的细胞分子中的碳-碳键，碳-氢键，氧-氢键等的伸缩振动，其谐振波大部分在3-15微米，和远红外线的波长和振幅相同，引起共振共鸣。石墨烯加热发射的8-15微米远红外波，能有激活身体细胞核酸蛋白质等生物分子等功能。除此之外，远红外线还具有改善人体血液循环、改善关节疼痛、调节自律神经、消炎、增强生物体的新陈代谢、护肤美容等诸多有益效果。
目前市场上还没有出现一种无需化学阻燃剂的，可释放负离子和远红外线的阻燃棉。
