Description
技术领域
本发明属于阻燃剂领域，具体涉及一种防火剂及其制备方法。
背景技术
防火剂又称阻燃剂，赋予易燃聚合物难燃性的功能性助剂，主要是针对高分子材料的阻燃设计的，广泛应用于各类装修材料的阻燃加工中。经过阻燃剂加工后的材料，在受到外界火源攻击时，能够有效地阻止、延缓或终止火焰的传播，从而达到阻燃的作用。但现有防火剂大多是粉剂制品，使用方法普遍为物理添加，需在聚合物材料未成型前与之混合，不适于已成型的产品，尤其是在各类纺织品中的应用更为困难，且粉剂防火剂与聚合物材料的相容性较差，燃烧时，产生的烟雾较大，抑烟效果差。
发明内容
针对现有技术的不足之处，本发明的目的在于提供一种防火剂及其制备方法。
本发明的技术方案概述如下：
一种防火剂，包括以下质量百分比原料：
优选的是，所述的一种防火剂，包括以下质量百分比原料：

本发明的有益效果：
1、本发明利用8-18wt％磷酸二氢铵、5-15wt％磷酸氢二铵、10-20wt％尿素、1-9wt％元明粉、0.5-1.5wt％AEO-9、余量去离子水复配水基液体防火剂，相比于传统粉剂防火剂，具有相容性良好、抑烟效果明显、使用方法灵活等优点，能够抑制燃烧过程中有毒有害烟雾的产生，适用于天然纤维织物、涤纶、绵沦、粘胶织物、无纺布等纺织品及木材、纸张、密度板等。
2、本发明防火剂不含卤素及重金属元素，无色无味，阻燃抑烟、稳定性好、不挥发、环保无毒、无腐蚀性，价格低廉，经其涂刷处理的纺织品阻燃性能达到“难燃B1”的国家标准。
3、本发明防火剂适用于各类已成型产品的阻燃处理，使用方法可为浸泡法、涂刷法、喷雾法，使用方便。
4、本发明利用元明粉在防火剂中起到平衡电解质的作用，使防火剂性能更稳定，并提高阻燃效果。
