阻燃PC/ABS合金的研制及其在电器上的应用

DEVELOPMENT AND APPLICATION IN ELECTRICAL APPARATUS OF FLAME-RETARDANT PC/ABS ALLOY

通过对3种增容剂增容PC/ABS合金性能的测试对比,选用了1种效果最佳的增容剂制备PC/ABS合金。用十溴联苯醚和三氧化二锑作为阻燃体系,对阻燃PC/ABS合金的力学性能、热性能、阻燃性能进行了检测。结果表明,当PC∶ABS∶增容剂∶阻燃体系为70∶30∶8∶15时,阻燃PC/ABS合金的综合力学性能最好,阻燃性能达到UL 94V-0级。该合金已用于生产防火电器开关、插座面板系列产品。

The optimal compatibilizer was selected to prepare PC/ABS alloy from three compatibilizer by comparing their effects on the properties of PC/ABS alloy. Decabromodiphenyl ether and antimony oxide were used as flame retardant system. The mechanical properties, thermal characteristics and flame retardance of flame retardant PC/ABS alloy were tested. The results showed that the mechanical properties of the alloy was the best, and the flame retardance reached UE 94 V - 0 grade when the proportion of PC, ABS, compatibilizer and flame retardant was 70/30/8/15. The alloy was used in the production of flame retardant electrical switch and socket.
