Description
技术领域
本发明涉及一种负离子功能材料及其制备方法，具体涉及一种板材用纳米负离子功能材料及其制备方法。
背景技术
随着空气电离理论的深入研究，人们对空气负离子发生的原理和应用引起了极大的兴趣。众所周知，空气是由多种气体组成的气体混合物，在某些能量场的作用下，气体分子中某些原子的外层电子会离开轨道，成为自由电子，而游离的自由电子又会与其它中性的分子相结合，使得到多余电子的气体分子呈负电极性，被称为“空气负离子”。自然界的负离子产生的原因，主要是宇宙射线、矿物放射线、电晕放电、水流瀑布和森林植物的光合作用。也就是说，负离子产生于某些物质内部潜在能量和大自然气象活动产生能量的激发。
负离子材料，是人类利用自然界产生负离子的原理，人工合成或者配比的一种复合矿物，因为其具有热电性和压电性，因此在有温度和压力变化的情况下(即使微小的变化)即能引起成分晶体之间的电势差，这静电高达100万电子伏特，从而使空气发生电离，被击中的电子附着于邻近的水和氧气分子并使它转化为空气负离子，即负氧离子。负氧离子具有以下功能：①可加速水分子运动，使普通水变成活性水，从而使水的渗透力、扩散力、溶解力、代谢力增强，并产生水保护膜。②对于循环系统，可起到扩张毛细血管，增强血液循环，促进新陈代谢，增强淋巴循环的作用；对于细胞组织，可使细胞活化，使老死细胞排泄或赋予再生能力，可增强细胞能量，增强细胞的功能和活力等作用，改善哮喘等呼吸系统疾病，改善情绪波动、抑郁心情、慢性疲劳，缓解精神紧张状况等，对人们的健康、情绪、精力大有裨益，③除粉尘，除浮毛，除异味，除烟，杀菌，净化空气，消除室内异味和各种有害气体。
由于现代工业发展，工厂废气交通排放井喷和家用装潢产品的增多，最终使生活的状态环境遭受严重破坏。根据相关统计，近几年室内空气质量严重下降，各类挥发性有机物、甲醛、氨等有害位置超标严重，而且随着大气污染的整体严重，颗粒物指标PM2.5，PM10等的数据高居不下。长期暴露于这类有毒有害环境中，将对健康产生不良影响。
在环境评价中，空气负离子浓度被列为衡量空气质量的一个重要参数。空气中适当浓度的负离子对消除悬浮在空气中的有毒有害气体和粉尘，抑制细菌霉菌和净化空气，对人们的健康长寿和生态环境，均具有及其重要的作用。随着人们对环境质量的要求越来越高，板材的高档化、功能化、环保化已成为板材生产企业发展的必然趋势，通过向板材中添加负离子功能材料可有效提高板材应用价值和功能。但是，目前国内对于板材用负离子功能材料的研究不多，这就对开发负离子板材带来了一定的困难。因此，开发一种板材用负离子功能材料具有重要的价值与意义。
