EPDM insulation modified with vinyl triethoxysilane functionalized GO to prevent plasticizer migration in solid propellant
Excessive plasticizer migration to the insulation will have a serious impact on the safety of solid propellants. In this paper, the anti-migration EPDM insulation was prepared by introducing vinyl triethoxysilane functionalized GO (GS) as modifiers to prevent the migration of energetic plasticizers....

| description | Excessive plasticizer migration to the insulation will have a serious impact on the safety of solid propellants. In this paper, the anti-migration EPDM insulation was prepared by introducing vinyl triethoxysilane functionalized GO (GS) as modifiers to prevent the migration of energetic plasticizers. The anti-migration performance at different temperatures was evaluated by immersion tests. The concentration of mixed plasticizers that migrated into the EPDM/GS-3 at 30 °C was decreased from 24.7% to 20.4% (17.4% decrease). The results confirmed that the introduction of GS prevented the migration of plasticizers to the EPDM insulation. The SEM results showed that GS was well-dispersed in the insulation, and there is strong interfacial interaction between GS and EPDM chains. Our research provided a new method to prepare EPDM insulation with excellent anti-migration performance. |
