| Abstract: |
| 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. |
