Its performances were showed and measured by the ways of elemental analysis, XRD, TG, DSC and IR. Its fireretardant mechanism and characteristic were discussed. Under burning, the fireretardant time of fivelayer wood panel coated the fireretardant paint is 24 min. The intumescent folds of the paint are 60~80.展开更多
将聚磷酸铵(APP)和三聚氰胺氰尿酸盐(MCA)复配作为主阻燃剂,以碳微球(CMS)为阻燃协效剂、聚丙烯(PP)为原料,通过熔融挤出法制备了复合材料,利用燃烧性能测试、TG、力学性能测试对复合材料的性能进行了研究。实验结果表明,在PP中加入26%...将聚磷酸铵(APP)和三聚氰胺氰尿酸盐(MCA)复配作为主阻燃剂,以碳微球(CMS)为阻燃协效剂、聚丙烯(PP)为原料,通过熔融挤出法制备了复合材料,利用燃烧性能测试、TG、力学性能测试对复合材料的性能进行了研究。实验结果表明,在PP中加入26%(w)的APP/MCA,所得复合材料的极限氧指数(LOI)达到28.4%,阻燃达到UL94 V0级,但强度和韧性下降。CMS可提高APP/MCA/PP的阻燃性和热分解温度,CMS含量2%(w)、APP/MCA含量26%(w)的CMS/(APP/MCA)/PP的LOI达到32.7%,阻燃为UL 942.0 mm V0级。保持CMS和APP/MCA的质量比为3∶23,当CMS/(APP/MCA)在CMS/(APP/MCA)/PP中的添加量为24%(w)时,所得阻燃PP的阻燃等级依然能达到UL 943.0 mm V0级。展开更多
