通过氧指数、力学性能测定及热重分析研究了纳米Sb2O3与十溴二苯醚(FR-10)配合使用时,纳米Sb2O3/环氧树脂复合材料的阻燃性、耐热性和力学性能,并与微米Sb2O3/环氧树脂体系进行了对比。结果表明,Sb2O3与FR-10共用时对环氧树脂具有明显的协同阻燃作用,Sb2O3的加入抑制了环氧树脂固化物的热分解;添加少量的Sb2O3就能达到较好的阻燃效果。加入纳米Sb2O3后材料的拉伸强度、弯曲强度和冲击强度均有提高。添加纳米级Sb2O3时体系阻燃、耐热和力学性能明显好于微米级Sb2O3填充体系。
The flame retardancy, heat resistance and mechanical properties of nano-Sb2O3 / epoxy resin composites were investigated by oxygen index, mechanical properties and TG analysis. And compared with micron Sb2O3 / epoxy system. The results show that Sb2O3 and FR-10 have obvious synergistic flame retardancy to epoxy resin. The addition of Sb2O3 inhibits the thermal decomposition of cured epoxy resin. Adding a small amount of Sb2O3 can achieve better flame retardant effect. After adding nano-Sb2O3 material tensile strength, bending strength and impact strength have increased. Adding nanoscale Sb2O3 flame retardant system, heat resistance and mechanical properties significantly better than the micron Sb2O3 filling system.
