Description

一种改进的环保阻燃剂组合物及其制备方法
技术领域
本发明涉及一种改进的环保阻燃剂组合物及其制备方法,特别是一种棉织物改进的环保阻燃剂组合物及其制备方法。
背景技术
随着纺织工业的发展,纺织品的品种和应用越来越广泛,从我们的日常生活扩展到交通运输、卫生、军事等领域,大部分纺织品本身不具备阻燃性而存在潜在的火灾危险,为了我们的生命和财产安全,阻燃纺织品显得尤为重要。生产阻燃纺织品一般有两种加工方法,一种是将阻燃剂混入纺丝原液中,直接制备阻燃纤维,这种加工方法只适用于合成纤维纺织品;另一种是阻燃后整理法,采用阻燃剂对织物进行阻燃整理,对于棉纤维等天然纤维纺织品,只能采用此种加工方法。
棉纺织品的耐久阻燃剂可分为卤系、磷系等。卤系阻燃剂在燃烧过程中会产生HCl、HBr等刺激性有毒气体,许多国家已禁止使用,逐渐被磷系阻燃剂取代,美国农业部南方地区研究所开发了以四羟甲基氯化磷为主的一系列棉耐久阻燃剂,后来英国Albright–wilson公司在此基础上开发了著名的Proban阻燃整理工艺;接着瑞士Ciba公司研制出了新型的耐久性阻燃剂Pyrovatex CP阻燃剂,学名为N–羟甲基–3–(二甲氧基磷羧基)丙酰胺(缩写为MDPPA),以上阻燃剂对棉纺织品耐久阻燃整理效果好,但因结构本身含有N-羟甲基或整理过程中加入缩醛类交联剂,使整理后棉纺织品上的甲醛含量严重超标,严重危害环境和身体健康,目前市场上销售和应用的棉用耐久阻燃剂仍以上述几种磷系阻燃剂为主。
因此,对上述磷系阻燃剂进行改进,开发一种改进的环保阻燃剂,使得阻燃效果更加优异,并减少甲醛等带来的健康和环境问题,具有非常重要的现实意义。
发明内容
本发明在于提供一种改进的环保阻燃剂组合物及其制备方法。与现已公开的棉用耐久阻燃剂及其制备方法相比,该发明独创性表现在如下几个方面:(1)本发明采用杂多酸,能够催化磷系阻燃剂与纤维素的羟基发生反应;(2)加入端羟基超支化聚酰胺,一方面吸收甲醛,另一方面与纤维素发生反应,提升耐久性,还一方面,它与磷系阻燃剂具有协同增效作用,大大提升阻燃性能。本发明制备的改进的环保阻燃剂组合物阻燃性能好,耐水洗,经其整理后的棉织物甲醛含量低,更环保。

2)加入杂多酸,室温搅拌10-20分钟;
3)加入端羟基超支化聚酰胺,室温搅拌10分钟,制得所述改进的环保阻燃剂组合物。
