摘　　要：利用自制的四苯基双酚A二磷酸酯(BDP)及其复配体系制备了阻燃ABS,研究了阻燃ABS的物理机械性能、氧指数(LOI)和垂直燃烧测试性能(UL94)、材料的阻燃性能和烟气释放。试验结果显示:酚醛树脂(NP)的加入可提高BDP阻燃体系的成炭效果,采用BDP/NP=20%/5%的体系阻燃ABS,材料的冲击性能下降了12.00%,LOI达到29.50%,UL94阻燃性能达到V-0级,av-HRR和pkHRR分别下降了46.40%和40.45%,TTI延长30 s,FGI下降了50.75%,6 min内的SEA上升了31.30%,600℃时成炭率为7.19%;采用BDP/NP/APP=20%/5%/5%时,材料的冲击性能降幅为36.00%,LOI最大可达30.10%,UL94阻燃性能为V-0级,av-HRR和pkHRR最大分别下降50.11%和55.58%,TTI延长35 s,FGI最大降幅为64.32%,6 min内的SEA升幅为20.52%,600℃时成炭率为11.15%;采用BDP/NP/纳米SiO2=20%/5%/7%时,材料的冲击性能上升了20.00%,LOI达到31.20%,UL94阻燃性能达到V-0级,av-HRR和pkHRR分别下降了49.45%和58.09%,TTI延长45 s,FGI降幅为68.34%,6 min内av-SEA升幅为13.00%,600℃时成炭率为16.37%,阻燃ABS的综合性能最好。Physical performances,the limiting oxygen index（LOI）,vertical combustion performances（UL94）,flame retardant performances,smoke release of bisphenol A diphosphate（BDP）,BDP/APP and BDP/SiO2 added in ABS are studied.The experimental results showed that BDP added in phenolic resin（NP） can increase char quality.As BDP/NP= 20 %/5 % was added in ABS,the maximum reduction parameter of physical performances is impact strength,which was reduced by 12.00 %,and the ABS resins passed the UL94V-0 test,LOI reached 29.50 %.CONE data showed that its average heat rate（av-HRR） and peak heat rate（pk-HRR） reduced by 46.40 %and 40.45 %,ignition time（TTI） increased 30 s,flame growth index（FGI） reduced by 50.75 %,average smoke extinction area（SEA） increased by 31.30 % in 6 minute,char ratio was 7.19 % at 600 ℃.When the BDP/NP /APP=20 %/5 %/5 % was added in ABS,ABS resins passed the UL94V-0 test,LOI reached 31.10 %,its reduction range of impact strength was 36.00 %,av-HRR and pk-HRR reduced by 50.11 %and 55.58 %,TTI increased 35 s,FGI reduced by 64.32 %,av-SEA increased by 11.14 % in 6 minute,char ratio was11.15 % at 600 ℃.Adding BDP//NP / SiO2 =20 %/5 %/7 %BDP into ABS resin,its impact strength increased by 20.00 %,the ABS resins also passed the UL94V-0 test,LOI reached 31.20 %,av-HRR and pk-HRR reduced by 49.45 % and 58.09 %,TTI increased 45 s,FGI reduced by 68.34 %,av-SEA increased by 13.00 % in 6 minute,char ratio was 16.37 % at 600 ℃.ABS resin added BDP/NP（20 %/5 %） and nanometer SiO2（7 %） has the best flame retarded and suppression smoke effect and the smallest influence on physical performances.
