Description

一种环保阻燃无纺布
技术领域
本发明涉及无纺材料技术领域，具体属于一种环保阻燃无纺布。
背景技术
无纺布(英文名：Non Woven)又称不织布，是由定向的或随机的纤维而构成，是新一代环保材料，具有防潮、透气、柔韧、质轻、不助燃、容易分解、无毒无刺激性、色彩丰富、价格低廉、可循环再用等特点。如多采用聚丙烯(pp材质)粒料为原料，经高温熔融、喷丝、铺纲、热压卷取连续一步法生产而成。因具有布的外观和某些性能而称其为布。目前全球性公害“环境污染”越来越严重，如塑料地膜的应用作为一种现代农业技术对农作物增产、农民增收，促进农业生产的发展作用很大。但是塑料地膜不可降解，带来了“白色污染”和使土壤板结，通透性变差，地力下降等问题。而当前，无纺布主要通过增加含溴、锑的化合物实现阻燃，或是通过添加氢氧化物、含磷阻燃剂等无卤素物质实现阻燃，前者燃烧后产生有害物质污染环境，后者阻燃性能不够好，且降低了聚丙烯原料的工艺性能。由于无纺布的原料如聚丙烯等为碳氢类材料，容易燃烧，目前制作阻燃性无纺布的过程通常是将无纺布在阻燃剂溶液中浸渍一段时间后，取出烘干，流程长且容易造成阻燃剂溶液的浪费。
发明内容
针对上述问题，本发明的目的是提供了一种环保阻燃无纺布，易分解阻燃效果好，且制造成本低廉的材料制成环保型无纺布。
本发明采用的技术方案如下：
