摘要
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),并与多聚磷酸铵(APP)、季戊四醇(PER)组成膨胀型阻燃剂(IFR)。采用二次回归正交设计方法,研究了APP、PER、TMM三变量对阻燃高密度聚乙烯(HDPE)氧指数(OI)的影响,得到关于OI的线性回归方程,并验证了其在=0.01水平上的显著性。结果表明:APP对OI影响最大,PER次之,TMM最小。实验配方验证了回归方程具有预见性。固定TMM的取值,得到关于OI-APP/PER的三维图和等高线。
2,4,6-tris（methylamino）-1,3,5-triazine （TMM） was synthesized from 2,4,6-trichloro-1,3,5-triazine and methylamine solution.The intumescent flame retardant （IFR） was prepared from APP,PER and TMM.The regression equation of OI dependant on TMM,APP and PER was gained by means of three-variable quadratic regression orthogonal design,and its significance at =0.01 was verified.The results show that APP is the most influencing factor,followed by PER,and the least is TMM.The experimental formulation proves the foreseeability of the regression equation.The three-dimensional maps and contour lines of OI-APP/PER are gained when TMM content is fixed.
