| 中文摘要: |
| 将氢氧化镁分别与炭黑N330、白炭黑、硼酸锌复配制得的无卤复配阻燃剂添加到天然橡胶（NR）中制备NR复合材料，对NR复合材料的性能进行研究。结果表明：随着氢氧化镁用量的增大，单一阻燃剂和复配阻燃剂NR复合材料的交联程度增大，硬度增大，拉伸强度和拉断伸长率减小；在复配阻燃剂用量相同时，氢氧化镁/白炭黑复配阻燃剂NR复合材料的拉伸性能最好；与单一阻燃剂NR复合材料相比，复配阻燃剂NR复合材料的极限氧指数显著增大，阻燃性能好；与单一阻燃剂NR复合材料相比，复配阻燃剂NR复合材料的热稳定性更好，残炭率更大，氢氧化镁/硼酸锌复配阻燃剂NR复合材料的热稳定性能最好。 |
| 英文摘要: |
| The halogen-free compound flame retardants prepared by compounding magnesium hydroxide with carbon black N330，silica and zinc borate were added to natural rubber（NR） to prepare the NR composites，and the properties of the NR composites were studied.The results showed that，with the increase of the magnesium hydroxide amount，the crosslinking degrees of the NR composites with single flame retardants and composite flame retardants increased，the hardnesses increased and the tensile strengths and elongations at break decreased.When the compound flame retardant amount was the same，the tensile properties of the NR composite with the magnesium hydroxide/silica compound flame retardant were the best.Compared with the NR composites with single flame retardants，the ultimate oxygen indies of the NR composites with the compound flame retardants significantly increased and the flame retardant properties were good.Compared with the NR composites with the single flame retardants，the thermal stabilities of the NR composites with the compound flame retardants were better，the residual carbon rates were higher.The thermal stability of the NR composite with the magnesium hydroxide/zinc borate compound flame retardant was the best. |
