针对当前有机高分子材料在阻燃方面的需求,结合聚丙烯阻燃作用机理,合成了一种高效的阻燃剂。对此,以C3_N_3(NH_2)_3、H_3PO_4和C_4H_(10)N_2作为试验的原材料,在探讨其合成反应机理的基础上,从配合比、反应时间和试验反应温度等不同角度构建最佳阻燃剂反应工艺,然后红外光谱分析等对该阻燃剂的合成进行了验证;将该制备的阻燃剂添加到PP聚丙烯材料中,并通过垂直燃烧测试、氧指数测试等验证了该阻燃剂合成的有效性。通过研究,进一步充实了当前阻燃剂制备理论,为有机高分子材料的合成提供了借鉴。

In view of the current demand for flame retardancy of organic polymer materials and the mechanism of flame retardancy of polypropylene, a high-efficiency flame retardant was synthesized. In this regard, the C_3 N_3（NH_2）_3, H_3 PO_4 and C_4 H_（10） N_2 were used as raw materials in the test, based on investigating its reaction mechanism, the best flame retardant reaction process was analyzed from the aspects of mixture ratio, reaction time and reaction temperature, and then the infrared spectrum analysis was used to verify the synthesis of flame retardant; The prepared flame retardant polypropylene material was added to the PP, and the flame retardant effectiveness was verified by vertical burning test, the oxygen index test,etc.Through the study, the theory of preparing flame retardant was further enriched, which could provide reference for the synthesis of organic polymer materials.
