摘要
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 -retardance, heat resistance and mechanical properties of nano -Sb2O3/epoxy composites using nano -Sb2O3 combined with deeabromodiphenyl oxide（ FR- 10）as flame retardents were investigated by oxygen index tests, mechanical property tests and thermal gravimetric analysis and compared with that of micro - Sb2O3/EP composites. The results showed that the Sb2O3 combined with FR- 10 had significant synergistic flame retardant effect on epoxy resin and the thermal decomposition of cured epoxy resin was suppressed by the addition of - Sb2O3. A small amount of Sb2O3 could achieve good flame retardant results. After adding nano Sb2O3, the tensile strength, flexural strength and impact strength were improved. The flame retardanee, heat resistance and mechanical properties of composites with nano -Sb2O3 were much better than that of micron Sb2O3 filling systems.
