| 中文摘要: |
| 采用水合肼/双氧水/硫脲体系对天然胶乳进行氢化改性制备氢化天然橡胶（HNR），研究HNR/氢氧化镁[Mg（OH）2]/环氧化天然橡胶（ENR）复合材料的微观结构和性能。结果表明：制备HNR的最佳氢化条件为水合肼/NR的C=C键物质的量比 5.5/1，双氧水/水合肼物质的量比 1.85/1，硫酸铜浓度 3.5 mmol·kg-1，表面活性剂浓度 20 g·kg-1；HNR/Mg（OH）2/ENR复合材料具有良好的界面相容性；HNR/Mg（OH）2/ENR并用比为10/5/5的复合材料极限氧指数达到20.7%，阻燃性能良好。 |
| 英文摘要: |
| Hydrogenated natural rubber（HNR） was prepared by using hydrazine hydrate/hydrogen peroxide/thiourea system to modify natural rubber latex.The microstructure and properties of HNR/magnesium hydroxide[Mg（OH）2]/epoxidized natural rubber（ENR） composites were investigated.The results showed that the optimum hydrogenation conditions for the preparation of HNR：the mole ratio of hydrazine hydrate/C=C double bonds of NR was 5.5/1，the mole ratio of hydrogen peroxide/hydrazine hydrate was 1.85/1，the concentration of copper sulfate was 3.5 mmol·kg-1，and the concentration of surfactant was 20 g·kg-1.The composites possessed good interfacial compatibility.When the blending ratio of HNR/Mg（OH）2/ENR was at 10/5/5，the limited oxygen index of the composites reached 20.7%，showing good flame retardant property. |
