改性PTFE对聚碳酸酯的阻燃抗滴性能研究

四氟

摘　要:研究了改性聚四氟乙烯（PTFE）微粉以及溴系阻燃剂十溴二苯醚（DBDPO）、超细无机阻燃剂A对聚碳酸酯（PC）阻燃防滴落性能的影响。结果表明，改性PTFE能够有效遏制PC的熔融滴落状态。与阻燃剂一起使用，垂直燃烧测试结果达到UL94V-0级。三者共同使用阻燃效果更佳。[著者文摘]

Study on Flame Retardant and Anti - dropping of PC Modified by PTFEDuan Xuan, Su Jielong, Chen Shuiping ,Wu Guozhong. 1. Wuhan University of Technology, Wuhan 430070 ; 2. Zhejiang Sinco Polymer R＆D Center, Jiashan 314100Abstract:The effects of PTFE micropowder, DBDPO and inorganic and anti - dropping behavior for PC were studied. It showed that PTFE had PC. When used with the flame retardant, the sample achieved the highest synergistic effect using three additives.
Key words: PTFE ; flame retardant ; PC ; anti - dropping
