Abstract

The flame retardant bisphenol AP bis(diphenyl phosphate) (BAPDP) is synthesized from triphenyl phosphate and bisphenol AP via transesterification, producing a polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) with a high flame retardancy and thermal stability. In this study, flame-retardant PC/ABS blends with various BAPDP contents are prepared, and their flame retardancy is studied using the limit oxygen index, vertical combustion, thermogravimetric analysis, and cone calorimeter testing. With a BAPDP content of 20 wt%, the product exhibits a limiting oxygen index of 25.4% and achieves the UL-94 V-0 grade, with a thermal deformation temperature of 72.6 °C. BAPDP improves the flame retardancy of the PC/ABS blends and exhibits fewer adverse effects on the thermal deformation temperature than other commercial flame retardants at the same concentration.

摘要

阻燃剂双酚AP双（磷酸二苯酯）（BAPDP）由磷酸三苯酯和双酚AP通过酯交换反应合成，可制备出具有高阻燃性和热稳定性的聚碳酸酯/丙烯腈-丁二烯-苯乙烯共聚物（PC/ABS）。在本研究中，制备了具有不同BAPDP含量的阻燃PC/ABS共混物，并使用极限氧指数、垂直燃烧、热重分析和锥形量热仪测试对其阻燃性进行了研究。当BAPDP含量为20 wt%时，产品的极限氧指数为25.4%，达到UL-94 V-0级，热变形温度为72.6℃。与相同浓度的其他商业阻燃剂相比，BAPDP提高了PC/ABS共混物的阻燃性，且对热变形温度的不利影响较小。
