| 中文摘要: |
| 以碱催化平衡聚合法制备的α，ω二羟基聚二甲基硅氧烷为基胶，制备氢氧化镁/氢氧化铝/三聚氰胺磷酸盐（MP）协效无卤膨胀型阻燃硅橡胶，并对其结构和性能进行研究。结果表明：氢氧化镁/氢氧化铝/MP可产生阻燃协同作用，能够使复合硅橡胶的阻燃性能、热稳定性能和抑烟性能进一步增强。氢氧化镁/氢氧化铝/MP阻燃硅橡胶不仅具有优异的阻燃性能，还能保持良好的物理性能，当复合阻燃剂氢氧化镁/氢氧化铝/MP并用比为12/18/30时，复合硅橡胶的综合性能最佳。 |
| 英文摘要: |
| The magnesium hydroxide/aluminum hydroxide/melamine phosphate（MP） filled retardant silicone rubber was prepared by using α，ω-dihydroxy polydimethylsiloxane，which was prepared by equilibrium polymerization by using alkaline catalyst，and the structure and properties of the flame retardant silicone rubber were investigated.The results showed that，the magnesium hydroxide/aluminum hydroxide/MP flame retardants possessed excellent synergistic flame retardant effect，and the flame retardancy，thermal stability and smoke suppression of silicone rubber composite were improved.The magnesium hydroxide/aluminum hydroxide/MP flame retardant silicone rubber also possessed good physical properties.As the magnesium hydroxide/aluminum hydroxide/MP blend ratio was 12/18/30，the comprehensive properties of the silicone rubber composite was the best. |
