The results shows that the flame-retarded effect of APP is better than Mg(OH)2. The cone calorimeter test shows that flame-retarded properties of composite containing 150 phr Mg(OH)2 had not obvious difference with one containg 70 phr A.

• 结果表明:APP的阻燃效果明显好于Mg(OH)2,锥形量热仪测试结果表明在阻燃性能上填充150份Mg(OH)2并不优于填充70份APP的聚丙烯阻燃材料;
