| titleOfInvention | Composition for preparing rubber material, rubber material and preparation method thereof, blowout preventer |
| abstract | The present application provides a composition for preparing a rubber material, a rubber material and a preparation method thereof, and a blowout preventer, belonging to the technical field of rubber material formulation. The composition for preparing the rubber material includes 100 parts by weight of nitrile rubber, 1-15 parts by weight of modified resin, 5-15 parts by weight of white carbon black, 4-14 parts by weight of vulcanization activator, and 1.5-3 parts by weight of vulcanizing agent and 0.5 to 3.5 parts by weight of a vulcanization accelerator. Phenolic resin modified with silane coupling agent can be combined with silica. The double bond contained in the modified resin undergoes vulcanization and cross-linking reaction, the cross-linking reaction between the modified resins forms a rigid resin cross-linking network, and the cross-linking reaction between the modified resin and the nitrile rubber forms an interpenetrating cross-linking network. , the interpenetrating cross-linked network can effectively increase the hardness and modulus of rubber, while improving oil resistance and thermal swelling properties. The synergistic reinforcement of the resin cross-linked network and the interpenetrating cross-linked network is used to improve the tensile strength and tear strength of the rubber material. |
