摘要：以三聚氯氰、亚磷酸三乙酯和丙三醇为原料，合成了一种反应型 P-N 膨胀型阻燃剂三氧代（3-磷酸二乙酯-
31

5-氯-1-三嗪）丙三醇（TTCTG），采用 FTIR、 HNMR、 PNMR、TG 对其进行了表征。通过极限氧指数（LOI）
和垂直燃烧实验、TG、SEM 测试了 TTCTG 对棉纤维（CF）的阻燃改性性能。结果表明，TTCTG 的热稳定性
良好。当 TTCTG 质量浓度为 200 g/L 时，阻燃整理后棉织物（TTCTG200-CF）的 LOI 为 27.3%，阻燃等级可达
国家标准 B1 级，同时仍能保持良好的力学性能。TTCTG 在 284 ℃便能促进棉织物快速分解成炭，700 ℃下的
残炭率高达 48.6%。TTCTG200-CF 燃烧后，其表面形成了致密的膨胀炭层，TTCTG200-CF 具有良好的阻燃性
能。水洗 20 次后，TTCTG200-CF 的阻燃等级仍可达 B1 级，LOI 可达 26.4%，TTCTG 与棉纤维通过共价键相
连而融为一体，赋予棉纤维优良持久的阻燃性能。

Abstract:Trioxo(3-diethylphosphate-5-chlorine-1-triazine)glycerol (TTCTG), a novel reactive P-N
intumescence flame retardant, was synthesized from cyanuric chloride, triethylphosphite and glycerol and

then characterized by FTIR, HNMR, PNMR and TG. The flame resistance of TTCTG on cotton fiber (CF)
were further analyzed by oxygen index (LOI), vertical combustion test, TG and SEM. The results showed
that TTCTG exhibited excellent thermal stability. The cotton fiber modified with TTCTG (TTCTG200-CF
with the mass concentration of TTCTG 200 g/L) showed a LOI of 27.3% while still maintained good
mechanical properties, and the flame resistance reached the class B1 of national standard of flame retardant
fabric. TTCTG could promote the rapid decomposition of cotton fabric into char at 284 ℃. The residual
carbon rate at 700 ℃ was as high as 48.6%. After TTCTG200-CF was burned, a dense expanded carbon
layer was formed on the surface, indicating excellent flame resistance. After washing 20 times, TTCTG200-
CF still maintained the class B1 flame resistance with a LOI of as high as 26.4%. TTCTG was integrated
with cotton fiber by covalent bond, giving cotton fiber excellent and durable flame resistance.
