Description

一种自粘合活性炭熔喷无纺布及其成布方法
技术领域
本发明涉及的是一种自粘合活性炭熔喷无纺布及其成布方法,自粘合活性炭熔喷无纺布可有效吸附各种工业废气,如苯、甲醛、氨气等,广泛应用于化工、制药、油漆等重污染行业作业防护,自粘合活性炭熔喷无纺布具备防毒和防尘的双重效果。
背景技术
目前市场上的活性炭无纺布通常采用粘合剂将活性炭和无纺布粘合在一起制作而成,或者是采用将活性炭颗粒撒布在基布上后,由喷头将喷丝直接喷射到活性炭颗粒上形成覆盖层,制成活性炭无纺布。前一种方法需要在胶粘剂中加入活性炭颗粒,按一定比例混合搅拌后,制成活胶碳混合物,然后涂抹到基布上。费工费力,而且胶粘剂会将基布原有的孔隙堵住,造成活性炭无纺布阻力大,也会造成活性炭的孔隙被堵塞或表面被胶裹住,粘住活性炭的同时,活性炭的吸附性能也下降。后一种方法是直接将高速喷射的喷丝喷到活性碳颗粒上,这种生产方法高速气流直接冲击在活性炭粉末颗粒上,不仅造成活性炭颗粒飞散弥漫到空气中,造成环境污染,粉尘达到一定浓度时还存在严重的爆炸安全隐患。同时由于高速气流的冲击,导致活性炭分布不均匀,存在炭布掉炭严重、吸附性能不够理想的缺点。
发明内容
本发明目的是针对上述不足之处提供一种自粘合活性炭熔喷无纺布及其成布方法(工艺),采用在底层熔喷布层上撒上活性炭颗粒形成活性炭层,然后采用自粘合无纺布层经过熔喷喷头的气流压力及收卷装置的复合压力,与活性炭层粘合在一起,熔喷喷头喷出的丝在自粘合无纺布层上形成,经过收卷装置后,制成的自粘合活性炭熔喷无纺布产品具有阻力低、活性炭含量高、吸附能力强、产品性能稳定性好、生产工艺简洁环保的优点。
