Summary: | The invention discloses a sealing ring material and a production process thereof. The sealing ring material comprises the following components in parts by weight: 75-85 parts of silane coupling grafting modified polyurethane rubber; 10 to 20 parts of fluorinated silane anti-drying modified fluorinated silicone rubber; 5-10 parts of functionalized nano-composite reinforced hydrogenated nitrile rubber; 1-2 parts of an anti-aging agent; 40-55 parts of a reinforcing agent, wherein the reinforcing agent is selected from one or more of carbon black and white carbon black; 5-10 parts of a vulcanizing agent; 8-15 parts of an accelerant; 15-25 parts of a plasticizer; compared with the prior art, not only is the anti-drying performance of the material improved, but also the physical and mechanical properties, such as oil resistance, wear resistance and high temperature resistance, of the material are enhanced, so that the sealing ring material can keep stable performance in a long-term dry environment.
