摘　　要：以三聚氯氰、二乙醇胺和乙二胺为原料,设计并合成了一种新型三嗪类成炭剂(CA),将其与聚磷酸铵(APP)、三聚氰胺(MA)复配成膨胀型阻燃剂(IFR),并用其对聚丙烯(PP)进行阻燃。使用混料设计的方法研究了CA对阻燃PP体系的阻燃性能和力学性能的影响。结果表明,所复配的IFR极大地改善了PP的阻燃性能。当IFR是由80.3%(质量分数,下同)的APP、13.0%的MA和6.7%的CA组成时,IFR对PP体系具有最有效的阻燃性。当PP中IFR加入量为30%时,阻燃PP体系的的极限氧指数(LOI)达到35.5%;当IFR加入量仅为25%时,阻燃PP体系的的阻燃性能也通过UL-94 V-0级,LOI值达到32.5%。A new triazine charring agent （CA） was designed and synthesized by using cyanuric chloride, diethanolamine and ethylenediamine as raw materials. The intumescent flame retardant （IFR） which was composed of ammonium polyphosphate （APP）, melamine （MA） and CA was used for the preparation of expansion flame retardant PP （polypropylene）. Effect of CA on flame retardancy and mechanical properties of intumescent flame retardant polypropylene （IFR-PP） system had been investigated by the method of mixture design. The results show that the IFR is very effective in flame retardancy of PP. When the components of the IFR are 80.3% APP, 13.0% MA and 6.7% CA, the IFR presents the most effective flame retardancy in IFR-PP systems. LOI of IFR-PP reaches 35.5% when the IFR loading is 30% in PP. It is also found that when the IFR loading is only 25% in PP, the flame retardancy of IFR-PP can still pass UL-94 V-0 rating, and its LOI reaches 32.5%.
