摘　　要：该文考察了4种抑烟剂的协同效应,对膨胀型防火涂料的抑烟效果。分别选用主族化合物及过渡金属化合物,包括Mg(OH)2、Sb2O3、二茂铁、Cu2O 4种抑烟剂。根据正交实验设计,选用四因素三水平,制备了9个样品。使用锥形量热仪测定其动态生烟性能。通过比较所得到的生烟速率及总生烟量,发现当Mg(OH)2、Sb2O3、二茂铁、Cu2O的质量分数分别为2%、1%、2%、1.5%时,对于膨胀型防火涂料的生烟量最小,抑烟剂的效果最好。同未添加抑烟剂的样品相比,生烟量下降46%。In this paper, the synergies of several smoke suppressants are studied. Herein, both main group components and sub-group components are investigated, including Mg （OH）2, Sb2O3, ferrocene, and Cu2O. The experiments are designed based on the orthogonal design, with 4 factors and 3 levels, that is, nine samples are prepared. Cone calorimeter is used to characterize the smoking performance of the flame-retardant intumescent coatings. The results shows that, when the quality percentage of Mg（OH） 2, Sb2O3, ferrocene, and Cu2O are 2% , 1% , 2% , and 1.5% respectively, the smoke amount of intumescent coatings is minimum. At this point, the cooperation of smoke suppressants meets the best. Compared to the original intumescent coatings,the total smoke rate decreases by 46%.
