S13、在3000-8000r/min分散条件下，向分散桶内分三次缓慢添加疏水沸石，第一次和第二次均高速搅拌10min，第三次搅拌30min；
S14、继续添加无机调稠剂，继续分散50min，之后将将分散机缓慢降速为为3200转/min；
S15、降速后依次加入消泡剂、润湿剂和抗水剂，分散12-14min，既得防水涂层，备用；
S2、将防水涂层涂覆在上下两层纤维纸层的外表面；
将纤维纸层装到窄缝涂布机上，将事先配制好的防水涂层经过涂布机上的挤压嘴一次性按照18-20克干重每平方米的规格涂布在原纸上，烘干即可；
S3、将纳米级活性炭层通过胶黏剂粘粘在上下两层纤维纸层之间的内表面，既得本发明的可防水办公打印纸。
