先以三聚氯氰和甲胺溶液为原料,合成了2,4,6-三甲胺基-1,3,5-均三嗪(TMM),再以TMM和磷酸合成了2,4,6-三甲胺基-1,3,5-均三嗪磷酸盐(TP),产率分别为90.3%和72.3%,采用FT-IR和TGA对合成产物进行了表征。研究了氢氧化铝(A l(OH)3)与TP并用对HDPE阻燃性能的影响。结果表明,并用TP和A l(OH)3提高了HDPE的氧指数,两者显示出阻燃协同效应。锥形量热结果表明,并用10%TP和40%A l(OH)3可使阻燃HDPE的最大热释放速率降低至348.47KW/m2,最大烟释放速率降低至0.032m2/s,分别比纯HDPE降低了50.6%和70.9%。
First, cyanuric chloride and methylamine solution were used as raw materials to synthesize 2,4,6-trimethylamino-1,3,5-s-triazine (TMM) Trimethylammonio-1,3,5-s-triazine phosphate (TP) were synthesized with the yields of 90.3% and 72.3% respectively. The synthesized products were characterized by FT-IR and TGA. The effects of aluminum hydroxide (Al (OH) 3) and TP on flame retardancy of HDPE were studied. The results showed that the oxygen index of HDPE was increased with TP and Al (OH) 3, which showed the synergistic effect of flame retardancy. The results of cone calorimetry show that the maximum heat release rate of flame retardant HDPE can be reduced to 348.47KW / m2 and the maximum smoke release rate to 0.032m2 / s with 10% TP and 40% Al (OH) 3, respectively Pure HDPE decreased by 50.6% and 70.9%.
