Description

一种沸石基调湿材料的制备方法
技术领域
[0001] 本发明涉及建筑材料领域,特别涉及一种沸石基调湿材料的制备方法。
背景技术
[0002]空气相对湿度是衡量室内环境的一项重要参数,对人体健康、室内空气质量以及物品的存放都有重要意义。目前,湿度调节的主要方式是借助人工高能源和机械设备,但其能耗大污染环境,且易引发“建筑综合症”。利用调湿材料的吸放湿特性来合理调控室内湿度,能耗低且无污染,是一种生态性控制调节方法。
[0003] 天然沸石属于无机多孔矿物材料,其内部微孔数量多、孔径分布广、比表面积大、吸附性能好、来源广泛、价格低廉。并且由于沸石孔穴中含有阳离子,骨架中含有负电荷,有较大的静电力,使得沸石具有良好的吸水能力,并且吸放湿速率快,是一种生态环保的建筑调湿材料。但天然沸石粉孔道中含有大量杂质,并且湿容量小,使其在建筑调湿方面的应用受到了限制。
发明内容
[0004] 本发明的目的就在于要克服上述现有技术存在的缺陷,而提供一种沸石基调湿材料的制备方法。
[0005] 本发明的制备方法,包括以下步骤:
[0006] I)预处理:将Ikg沸石粉用去离子水洗涤3遍,去除可溶性杂质,后将样品于电热鼓风干燥箱中100-105 °C烘干6-12h;
[0007] 2)将预处理后的沸石粉置于箱式实验电炉中300°C下煅烧l_2h,去除沸石孔道中的沸石水及杂质;
[0008] 3)将沸石粉与质量百分比为20%_30%的氯化钙或氯化镁溶液按固液比1: 5配制成溶液;
[0009] 4)将配制的溶液装于玻璃器皿中于常温下静置2d其每间隔2h用玻璃棒搅拌一次,或置于恒温水浴箱中水浴加热90min,其每间隔20min用玻璃棒搅拌一次;
[0010] 5)过滤并用去离子水冲洗沸石粉至少3-5次,在电热鼓风干燥箱中100-105°C下烘干6-12h,在玻璃干燥器中冷却至室温,密封保存。
[0011] 本发明的有益效果:
[0012] I)沸石粉价格低廉,分布广泛容易获得;
[0013] 2)制备方法简单易行,生产能耗较低:
[0014] 3)沸石基调湿材料的吸放湿速率快,吸放湿容量大,具有良好的调湿性能;
[0015] 4)绿色无污染,属于环境友好型调湿材料;
[0016] 5)沸石基调湿材料具有较大的吸放湿率及较小的吸放湿滞后率,改性后的沸石吸湿率比未改性沸石的吸湿率提高了 3-4倍,改性后的沸石放湿率比未改性前提高了 4-5倍。
附图说明
[0017]图1是天然沸石粉吸湿前和吸湿平衡后的对比图。
[0018] 图2是沸石基调湿材料吸湿前和吸湿平衡后的对比图。
