Description

一种口罩用吸附剂及其制备方法
技术领域
本发明涉及吸附剂领域，尤其涉及一种口罩用吸附剂及其制备方法。 
背景技术
近几年雾霾天气越来越严重，PM2.5严重超标，雾霾中含有大量病菌和粉尘，给人们的健康带来了极大的威胁，目前的普通的口罩吸附剂基本以活性炭为主，但是活性炭对颗粒污染物的吸附和过滤效果有限，大气中各种有机废气污染物也逐渐增多，活性炭吸附剂不能分解除去这些污染物，即便吸附到口罩上，也对人体健康有影响，因此为了保障人们的身体健康，需要对口罩吸附剂进行改进。 
发明内容
本发明的目的在于提供一种口罩用吸附剂及其制备方法，该吸附剂对空气的中细菌、PM2.5具有良好的阻隔作用，而且能够催化氧化甲醛等有害物质，还能够杀菌，不妨碍透气性。 
本发明的技术方案如下：

所述口罩用吸附剂的制备方法，其特征在于包括以下步骤： 
(1)将柠檬酸、氧化铁、氧化镧、氢氧化铝、纤维素钠混合，加入7-9倍重量份的水，搅拌10-14小时，在70-80℃下蒸发脱水，至含水量为4-6%，在 200-250℃下煅烧1-2小时，粉碎，过100目筛，得到颗粒；
(2)将除了助剂之外其他剩余成分混合，加水，造粒，在500-600℃下焙烧30-40分钟，粉碎过30目筛，得到颗粒；
