| 摘 要： | 活性阻燃剂2,4,6-三溴苯酚(TBP)在环氧树脂(EP)酸酐固化物中具有较好的阻燃效果,TBP用量在20phr左右时固化体系可以达到自熄。当TBP与三氧化二锑(Sb2O3)配合使用时,由于协同效应,同时发挥气相阻燃作用和凝聚相阻燃作用,其阻燃效果更佳。而平均粒径为100nm的丁苯吡弹性纳米粒子(VSBENP)能明显增韧TBP/EP活性阻燃体系,同时还可提高其耐热性;用量控制在15phr时增韧效果最好,其冲击强度比未添加增韧剂时增加了112%,当其用量大于25phr时,过多的纳米粒子易于结团,难以充分发挥其纳米效应,导致增韧效果减弱。

| Abstract: | 2,4,6-tribromophenol has good flame retardance effect in cured epoxy resin. The latter can be self-extiguished as TBP level is 20phr. ,If TBP is compounded with Sb2O3 , due to compatibility effect, the flame-retardant acting is exerted both by gas phase and by condensed phase simultaneousl6y, so that the flame-retardance effect is improved greatly. when the average grain site of VSBENP is 100nm, the toughening and thermal resistance of TBP/EP can be improved, when the TBP level being 15phr is to be controlled, the toughening effect is the best, and the impact strength can be increased by 112% (compared with no toughting). When VSBENP level is greater than 25phr, it results in toughtening effect weakened because of the excess nano- grain being liable to agglomerate, losing nano-effect. |
