摘要
研究了磷酸三苯酯(TPP)、间苯二酚双(二苯基磷酸酯)(RDP)、缩聚型固体磷酸酯(PX)和增容增韧剂对聚碳酸酯(PC)/丙烯腈丁二烯苯乙烯共聚物(ABS)合金阻燃性能的影响。结果表明,TPP、RDP、PX均可显著提高PC/ABS合金的阻燃性能,增容增韧剂可以改善体系的力学性能;当PC/ABS为7/3时,分别加入11%(质量分数,下同)、14%和12%的3种阻燃剂,并配以适量的增容增韧剂和其他助剂,可以制得等级为UL 94 V-0级的PC/ABS合金。
The effects of triphenyl phosphate （TPP）, resorcinol bis（diphenyl phosphate） （R DP）, and PX on the flame retardancy of PC/ABS blends were studied. All the phosphate could improve the flame retardaney of PC/ABS blends effectively. Into a PC/ABS blend of weight ratio 7/3, 11 wt% of TPP or 14 wt % of RDP or 12 wt % of PX were introduced, UL 94 grade of V-0 could be obtained. In addition, the positive effect of a compatibilizer on the mechanical properties of PC/ ABS alloy was also observed.
