| Abstract: |
| The flame retardant RTV-1 silicone rubber was prepared by using α，ω-dihydroxyl polydimethylsiloxane，which was prepared by equilibrium polymerization with alkali catalyst，and the influence of the addition level of flame retardant MPP on the flame retardant properties，physical properties and thermal stability of dealcoholized silicone rubber was investigated.The results showed that，as the addition level of MPP was over 30 phr，the flammability test showed that the silicone rubber reached V-0 rating of ANSI/UL 94-2010.As the addition level of MPP increased，the peak of heat releasing rate and smoke releasing rate of silicone rubber decreased，the Shore A hardness，tensile strength and tear strength increased，and the elongation at break decreased.The initial decomposition temperature of the silicone rubber decreased when the flame retardant MPP was used. |
