Description

可释放负离子的多孔雾化芯及其制备方法
技术领域
本发明涉及雾化技术领域，尤其涉及一种可释放负离子的多孔雾化芯及其制备方法。
背景技术
随着雾化行业的持续发展，多孔雾化芯的使用也逐渐成为人们生活中的一部分，但因为不同的使用领域，雾化液的多样性，普通的雾化芯并不能保证能长时间雾化，雾化液的过期生菌也大大降低了雾化器的使用寿命，特别是在电子烟雾化和医疗雾化行业。并且，随着人们对健康理念的不断追求，研究一种健康环保的雾化芯显得尤为重要。
目前，解决办法之一就是选择环保材料，并且定期更换雾化芯，这样不仅大大限制了雾化芯的使用范围，并且使得使用成本增高。

附图说明
下面将结合附图及实施例对本发明作进一步说明，附图中：
图1是本发明中二次改性电气石的SEM图；
图2是本发明的可释放负离子的多孔雾化芯的SEM图。
具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
本发明的可释放负离子的多孔雾化芯，包括原料及其质量份数如下：电气石50-90份、陶瓷粉体0-30份、造孔剂10-30份、助烧剂0-30份、石蜡0-35份以及表面活性剂0-2份。
其中，电气石是一种环状结构的硅酸盐矿物，由于其特殊的晶体结构，具有永久性的自发极化效应，使其有热释电、压电、红外辐射、释放负氧离子及生物电特性。电气石产生的远红外可杀死雾化液中细菌，促进血液循环，促进新陈代谢；电气石产生的负离子可以将雾化液电离，使其变成弱碱性，更利于身心健康；电气石产生的微电流与人体生物微电流一致，可以引起人体生物电现象。
电气石优选粒度为100目-1500目。
进一步地，为提高电气石负离子、远红外释放性能，对电气石进行改性，使其形成一次改性电气石或二次改性电气石。
一次改性电气石经以下改性方法得到：将100份电气石加入适量的质量分数为1％-10％的水合硝酸铈溶液(水合硝酸铈溶液)中，混合后置于层析柱中循环过载2-5h，再将过载完的悬浊液进行磁力搅拌，缓慢滴加质量分数为5％-10％的氨水，待PH值为10时停止滴加，再加纯水搅拌洗涤多次(如两次)，滤去清液，在烘箱中70℃-90℃烘干，再置于烧结炉中500℃-600℃煅烧4-6h，煅烧后得到的产物即为一次改性电气石。
将上述的一次改性电气石再进行改性，即可得到二次改性电气石，改性方法如下：取100份一次改性电气石和200份的无水乙醇，混合后于磁力搅拌上搅拌，再加入60份的钛酸丁酯，搅拌2-3h，搅拌完成后滤去清液，在烘箱中70℃-90℃烘干，再置于烧结炉中450℃-550℃煅烧3-4h，煅烧后得到的产物即为二次改性电气石。
二次改性电气石的SEM图如图1所示，从图1中可看出，二次改性后的电气石表面光滑。电气石在复合TiO2后，表面出现了较多的细小颗粒，说明改性结果较佳。
其中，一次改性时，Ce(铈)存在两种可变价态，Ce3+在光照条件下可转变为Ce4+，转化过程中存在电子-空穴复合，而电气石两端的静电场的存在会使得参与复合的电子在电场的作用下发生迁移，从而降低了电子-空穴的复合机率，使得电气石/Ce复合材料表面积聚了大量的能量，从而导致负氧离子释放量增加；二次改性时，生成二氧化钛具有光催化效应，不仅可提高一次改性的效果，而且在光线或紫外线照射下，TiO2表面的电子吸收足够的能量而脱离，促进电气石负离子和远红外等的释放效果。
陶瓷粉体包括负离子粉、远红外粉、凹凸棒土、长石及沸石的至少一种，粒度为100目-1500目。其中，长石为钾长石和/或钠长石。
助烧剂为金属氧化物、玻璃粉中至少一种，粒度为325目-2000目，始熔温度为300℃-500℃。金属氧化物可为氧化镁、二氧化钛、氧化铌等中至少一种。
造孔剂为小麦粉、PS微球、C粉(碳粉)及谷壳粉中至少一种，粒度为80目-1000目。
石蜡为半炼或精炼石蜡，熔点为40℃-100℃。
表面活性剂为失水山梨醇脂肪酸酯(司盘)、聚山梨酯(吐温)、硬脂酸及油酸中至少一种。
本发明的可释放负离子的多孔雾化芯的制备方法，包括以下步骤：
S1、按质量份数将各原料混合，压制形成坯体。
对于压制成型，可以采用热压铸成型，也可以干压成型。
进一步地，对于热压铸成型，原料中，助烧剂优选10-30份，石蜡优选15-35份，表面活性剂优选0.05-2份。
对于干压成型，原料中可不需添加助烧剂、石蜡和表面活性剂。
S2、将坯体置于烧结炉中，按1℃/min-10℃/min的升温速率升温至600℃-800℃进行烧结，以一次烧结方式得到多孔雾化芯。
可以理解地，本发明的可释放负离子的多孔雾化芯的制备方法不限于上述热压铸或干压，其他成型制备雾化芯的方法均可采用。
本发明的可释放负离子的多孔雾化芯的SEM图如图2所示，从图可看出，雾化芯孔隙较多且孔隙均匀，均匀的孔隙能充分保证电气石功能的作用效果，且使雾化效果更佳。
以下通过具体实施例对本发明作进一步说明。
实施例1
各原料份数如下：未改性的电气石80份，玻璃粉20份，小麦粉20份，石蜡20份，油酸0.5份；将上述原料混合后进行热压铸成型，于600℃-800℃下一次烧结，形成多孔雾化芯。

比较例1
将实施例1中的电气石替换为氧化铝，其余与实施例1相同。
对实施例1-5及比较例1得到的雾化芯的释放负离子性能进行测试：采用COM-3010PRO固体负离子测试仪、COM-3200PRO II空气负离子测试仪测试固体和空气负离子含量，空气负离子在1m3的密闭空间内测试20-60min，雾化芯试样尺寸为厚1cm、直径10cm的圆片。测试结果如下表1。

由表1可知，本发明中电气石的加入，使雾化芯具有负离子释放等功能，且改性后的电气石效果更佳；负离子粉也具有相同的效果。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
