摘要
研究了多聚磷酸铵(APP)、APP/PER(季戊四醇)复配比及其用量对丙烯腈-丁二烯-苯乙烯(ABS)的阻燃性能及力学性能的影响。同时也研究了增韧剂聚硅氧烷、甲基丙烯酸甲酯-丁二烯-苯乙烯共聚物(MBS)的用量对阻燃ABS的阻燃性能及力学性能的影响。结果表明,APP与PER复配质量比为3∶1时协同阻燃效果较好,其填加量为30份以上时阻燃料ABS可达到UL94V-0级,阻燃剂的加入对其力学性能影响并不明显。聚硅氧烷和MBS加入后,冲击强度有一定程度的提高,但阻燃性能有了很大程度的下降。
The effects of loading of ammonium polyphosphate （APP） and pentaerythritol（PER）, and their weight ratio on the mechanical and retardant properties of ABS were studied. The same effects of toughening agents of polysioxane and MBS were also studied. It showed that APP and PER had excellent synergistic effects on the flame retardancy of ABS. When the weight ratio of APP to PER was 3 ： 1 and the content of flame retardants exceeded 30 phr, a grade of UL94 V-0 was achieved. The content of flame retardants had moderate effect on mechanical properties. When polysioxane or MBS was added to ABS together with 30 phr flame retardant, the impact strength slightly increased and retardant properties were seriously decreased.
