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.
