摘要:
将磷杂菲/三嗪双基协同阻燃剂（TGD）、甲基膦酸二甲酯（DMMP）、可膨胀石墨（EG）及氢氧化铝（ATH）复配添加到天然橡胶（NR）中制备阻燃NR硫化胶，考察了TGD/DMMP/EG/ATH复配阻燃剂对NR硫化胶的阻燃性能、热稳定性及物理机械性能的影响。结果表明，TGD/DMMP/EG/ATH复配阻燃剂可有效提升NR硫化胶的阻燃性能和热稳定性，并降低燃烧过程中的热释放速率。当TGD/DMMP/EG/ATH复配阻燃剂的用量为60份（质量）时，NR硫化胶的极限氧指数可达28.4%，残炭质量分数可达25.61%，热释放速率可降低95%，总热释放量可降低21%。TGD/DMMP/EG/ATH复配阻燃剂对NR硫化胶的物理机械性能影响不大。
Abstract:
The flame retardant natural rubber （NR） vulcanizates were prepared by adding phosphoxanthrene/triazine bibase synergic flame retardant（TGD）, dimethyl methyl phosphonate （DMMP）, expandable graphite （EG） and aluminum hydroxide （ATH） to NR. The effects of TGD/DMMP/EG/ATH compound flame retardants on the flame retardancy, thermal stability and physical and mechanical pro-perties of NR vulcanizate were investigated. The results showed that TGD/DMMP/EG/ATH compound flame retardant could effectively improve the flame retardancy and thermal stability of NR vulcanizates, and reduce the heat release rate during combustion. When the amount of TGD/DMMP/EG/ATH compound flame retardant was 60 phr （mass）, the limiting oxygen index of NR vulcanizates could reach 28.4%, the mass fraction of carbon residue could reach 25.61%, the heat release rate and total heat release amount of NR vulcanizates could be reduced by 95% and 21%. TGD/DMMP/EG/ATH compound flame retardant had little effect on the physical and mechanical properties of NR vulcanizates.
