Description

活性炭布的生产方法
技术领域
本发明涉及复合材料的制备技术领域，尤其涉及一种活性炭布的生产方法。
背景技术
现有技术中，活性炭布一般采用是通过有机粘接剂通过涂布或浸渍工艺将活性炭粉粘合到PP布、无纺布等类型的基材上，干燥后制得成品。这种方法制得的活性炭布，一方面活性炭布会被大量粘接剂包裹，活性炭与空气接触的面积大大减小，使其吸附和净化能力大大降低，采用这种活性炭布制得的口罩、净化器滤芯等产品的空气净化能力变差；另一方面，由于大量使用粘接剂和有机溶剂，容易对环境造成二次污染，同时对用户的身体健康有潜在危害；另外，涂布或浸渍工艺除了大量使用胶粘剂，其效率也低，不利于大规模生产。
现有的活性炭布生产方法通常将PP塑胶颗粒加热熔化，经吹塑形成PP布；将活性炭、表面活性剂加入到水中，超声分散，得到活性炭的分散液；将所得的PP布加入到活性炭的分散液中，超声振荡一定时间，再冷冻干燥，得到复合体；将所得的复合体进行热压，得到活性炭布。
这种生产方法具有以下缺点：
(1)工序繁琐，生产效率低；
(2)使用胶粘剂量大，成本高，不环保。
此外，现有的活性炭布制备方法中阻燃活性炭布是在经阻燃处理的基材上依次覆盖有活性炭层、水性胶膜层和热熔胶粉粒层。这种制备方法通过用环保水性阻燃剂在基材上喷胶或浸轧烘干后，将配制好的炭浆以及水性阻燃热熔胶粉粒浆依次均匀涂布在基材上，经烘干后即得到阻燃活性炭布，在烘干的过程中，炭层与热熔胶粉粒层之间形成水性胶膜层。
这种生产方法具有以下缺点：
(1)工序繁琐，生产效率低；
(2)使用胶粘剂量大，成本高，不环保。
