| Abstract: |
| Based on aluminum hydroxide and glass powder as flame retardant，ceramic silicone rubber was prepared by addition platinum complex and refractory filler（wollastonite，mica powder and kaolin）as methylvinysilicone rubber as matrix material.The effect of platinum complex and refractory filler on the physical property，thermal stability and sintering property of ceramic silicone rubber was investigated.The results showed that，platinum complex and aluminum hydroxide had good synergistic flame retardancy effect on silicone rubber，the suitable mass fraction of platinum complex was 7.2×10-6.With the addition level of refractory filler increasing，the physical properties of silicone rubber decreased.The suitable addition level of refractory filler was 20 phr.The thermal stability of silicone rubber with platinum complex and refractory filler decreased.As ablation temperature rose，ceramic effect of sintering product of silicone rubber was more obvious.Ceramic silicone rubber had excellent flame retardancy and refractory properties.The physical properties and ceramic effect of silicone rubber with mica powder were best. |
