摘要：【中文】本发明属于无卤阻燃技术领域，具体是涉及一种含磷多乙烯多胺阻燃剂及其制备方法。其分子结构式为：式中，R为乙基、苯基、乙氧基或苯氧基。首先将多乙烯多胺溶于有机溶剂中，然后加入无机碱和有机碱，在0～5℃和氮气保护条件下，逐滴加入磷酰氯，滴加完毕后接着继续反应，然后升温在氮气条件反应，最后将所得产物过滤去沉淀后除溶剂，得到的淡黄色胶体即含磷多乙烯多胺阻燃剂。由于本发明的含磷多乙烯多胺阻燃剂的磷、氮元素含量均较高，二者之间存在协同阻燃效应，使得复合材料在受热或燃烧过程中，能快速促进聚合物碳化，隔氧隔热，降低可燃气体和有毒烟气释放。同时，配合少量的阻燃协效剂，可以进一步提高复合材料的阻燃性能。 【EN】The invention belongs to the technical field of halogen-free flame retardance, and particularly relates to a phosphorus-containing polyethylene polyamine flame retardant and a preparation method thereof. The molecular structural formula is as follows:in the formula, R is ethyl, phenyl, ethoxy or phenoxy. Firstly, dissolving polyethylene polyamine in an organic solvent, then adding inorganic base and organic base, dropwise adding phosphorus oxychloride at 0-5 ℃ under the protection of nitrogen, continuing to react after dropwise adding, then heating to react under the condition of nitrogen, finally filtering the obtained product to remove the solvent after filtering out the precipitate, and obtaining the faint yellow colloid, namely the phosphorus-containing polyethylene polyamine flame retardant. Because the phosphorus-containing polyethylene polyamine flame retardant has higher contents of phosphorus and nitrogen elements and has a synergistic flame retardant effect between the phosphorus-containing polyethylene polyamine flame retardant and the nitrogen elements, the composite material can quickly promote the carbonization of polymers, insulate oxygen and heat and reduce the release of combustible gas and toxic smoke in the heating or burning process.
