摘要: 将自制的超支化三嗪成炭剂(CFA)与聚磷酸铵(APP)以1∶1的比例复配成膨胀型阻燃剂(IFR),用于聚丙烯(PP)的阻燃。采用冲击实验、拉伸实验、极限氧指数仪、垂直燃烧(UL 94)和扫描电子显微镜 (SEM)等方法表征了PP阻燃复合材料的力学性能、阻燃性能,分析了断面形貌。结果表明,添加阻燃剂后,冲击强度呈先增加后降低的趋势,拉伸强度则随着阻燃剂含量的增加不断下降,但降幅不明显;含有15 % IFR的阻燃复合材料,其垂直燃烧等级即可通过UL 94 V-0级测试,显示出复合IFR具有优秀的阻燃效果。

Abstract: An intumescent flame retardant (IFR) was prepared by mixing a hyperbranched triazine charring agent with ammonium polyphosphate at a mass ratio of 1∶1 and then used for the flame retardancy of polypropylene (PP). The mechanical and flame-retardant properties of the resulting flame-retardant PP are evaluated by means of impact and tensile measurements, LOI test and vertical burning experiment, and the cross-section morphology was observed by SEM. The characterization results indicated that the impact strength of flame-retardant PP increased first and then tended to decrease with an increase of IFR content. However, the tensile strength exhibited a continual decrease with increasing the content of IFR. The flame-retardant PP containing 15 % IFR achieved a UL 94 V-0 classification, implying an excellent flame retardant effect.

Key words: flame retardant, charring agent, polypropylene, mechanical property
