| 中文摘要: |
| 以纳米氢氧化镁粉体为分散相研究对象，制备纳米氢氧化镁/NBR、纳米氢氧化镁/EPDM、纳米氢氧化镁/SBR和纳米氢氧化镁/硅橡胶4种复合材料，研究其物理性能和阻燃性能。结果表明，纳米氢氧化镁赋予复合材料良好“无卤”阻燃性能的同时，具有优异的补强效果；纳米氢氧化镁粉体分散度越高，与基体的界面作用越强，复合材料的物理性能越好；纳米氢氧化镁对NBR补强效果最好，对硅橡胶的补强效果最差。对纳米氢氧化镁粉体进行表面处理，可提高其在EPDM中的分散度，增大其与橡胶间的界面作用力，从而显著提高EPDM复合材料的物理性能。 |
| 英文摘要: |
| The nano-magnesium hydroxide/NBR，nano-magnesium hydroxide/SBR and nano-magnesium hydroxide/EPDM and nano-magnesium hydroxide/silicone rubber composites were prepared，and their physical properties and flame retardance were investigated.The results showed that the magnesium hydroxide gave the composites good halogen-free flame retardance combined with the excellent reinforcement efficiency；the higher the dispersity of nano -magnesium hydroxide powder，the stronger the interfacial action between nano-magnesium hydroxide powder and rubber matrix，and the better the physical properties of composite；in terms of reinforcement efficiency，the nano-magnesium hydroxide was the best for NBR and the poorest for silicone rubber.The dispersity of nano-magnesium hydroxide powder in EPDM and the interfacial action improved by the surface modification of powder，thus the physical properties of the composite improved. |
