| titleOfInvention | Aging-resistant ethylene propylene diene monomer sealing material and preparation method thereof |
| abstract | The invention discloses a preparation method of an aging-resistant Ethylene Propylene Diene Monomer (EPDM) sealing material, which is characterized in that carboxyl is introduced to EPDM molecules through reactive processing, so that the polar affinity of the EPDM molecules and unsaturated carboxylate is enhanced on the one hand, and meanwhile, the EPDM molecules react with metal oxide to form ionomer in the in-situ generation process of the unsaturated carboxylate in a rubber matrix, so that the crosslinking density of a rubber composite system is improved; further, the excellent reinforcing and anti-aging stabilizing effects of graphene are utilized, unsaturated carboxylic acid is subjected to intercalation modification, the interfacial compatibility of the unsaturated carboxylic acid and an EPDM matrix is enhanced, and the unsaturated carboxylic acid can also react with metal oxide to form an ionic bond effect, so that the intermolecular interaction and the crosslinking density of an EPDM rubber system are greatly improved, the mechanical strength and toughness and the anti-aging stability of the EPDM rubber system as a sealing material are improved, and the service life of the EPDM rubber system is prolonged. |
