EPDM改性对其绝热材料性能的影响
Effects of modification of ethylene-propylene-diene monomers on performances of their insulations
摘要
Abstract
A new EPDM insulation with excellent adhesion properties for solid rocket motors was fabricated based on modifica-tion of EPDM rubber by means of double screw extrusion processes,and improved EPDM and non-improved EPDM was simultane-ously applied,at the same time several function fillers were added in order to enhance their mechanical properties and improve adhe-sion properties.Effects of the amount of modified EPDM rubber on the mechanical properties,ablative performance and adhesive properties of the insulations were investigated. Results show that the insulation presents excellent mechanical properties, ablative properties and adhesive properties when the amount of modified EPDM is 15 phr.Adhesion properties between the insulations with metal materials can also be improved through optimization of adhesion processes. For instance,shear strength for the insulators with sheets of alumina and 45# steel is 6.11 MPa and 7.38 MPa respectively,through further improving vulcanization and hot pressing processes.The patterns of adhesive failure between the insulators and metals exhibits cohesive failure.关键词
