Description

一种新型阻燃无纺布的制备方法
技术领域
本发明涉及一种抗菌材料，具体为一种新型阻燃无纺布的制备方法。
背景技术
阻燃无纺布按工艺可分为阻燃针棉和阻燃热风棉。阻燃针棉是经针刺机穿刺后纤维纠结而成；阻燃热风棉主要是经铺网后热风过炉形成。两种产品都有自己的特点，共性是阻燃防火、轻便、保暖、耐用、环保。阻燃剂分为很多种，有卤系阻燃剂、有机磷系及磷-卤系阻燃剂、膨胀型阻燃剂以及无机阻燃剂。目前使用最多的是卤系阻燃剂中的溴系阻燃剂。
发明内容
本发明的目的在于提供一种新型阻燃无纺布的制备方法，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：一种新型阻燃无纺布的制备方法，其特征在于采用200份PP颗粒、10-15份阻燃母粒、0.3-0.8份乙烯基硅油、0.1-0.5份色母粒混合后送入螺杆挤出机，经过熔融挤出、纤维形成、纤维冷却、成网、加固而得本发明新型阻燃无纺布。
作为优选，所述阻燃母粒包括以下组分：
A.将100份聚烯烃弹性体、10-15份双苯基链节高温硫化苯基硅橡胶、6-7份四丁基氢氧化磷、2-3份芳香油、超高分子量聚乙烯纤维12-15份、十溴二苯乙烷5-8份、硅烷偶联剂1-2份、三聚氰胺0.5-1份混合，导入预备溶液，在高速搅拌机中搅拌30-40分钟，得到混合物；
B.将混合物送入干燥箱内80—90℃下烘燥约1—1.5小时，将混合物加入双杆螺旋挤出机中，控制挤出机温度为220-230℃，熔融挤出，得到阻燃母粒。
发明效果：
1.质轻、柔软：以聚丙烯树脂为主要生产原料具蓬松性，由细纤维组成(2-3D)轻点状热熔粘结成型。成品柔软度适中，具舒适感，手感好。
2.拨水、透气：聚丙烯切片不吸水，含水率零，成品拨水性佳，由100%纤维组成具多孔性，透气性佳，易保持布面干爽、易洗涤。
3.本发明能通过美国CFR1633测试的产品特点:阻燃，抗熔融，少量烟气，不释放毒气，具有自灭效果，碳化后能保持原状，吸湿，透气，手感柔软，弹性持久，30秒内自动熄灭，主要适用于高档商品。
