The invention relates to the technical field of sealing rings, in particular to a high-elongation and flame-retardant rubber sealing ring, a production process and an edge removal device. parts, expandable graphite 20-40 parts, zinc oxide 4.8-5.2 parts, alumina 0.58-1.25 parts, nano titanium nitride 0.9-1.8 parts, stearic acid 1.5-2 parts, accelerator 0.5-1 part, calcium carbonate 12-15 parts of powder, 5.8-10.8 parts of anti-aging agent, 1-2 parts of vulcanizing agent, 8.5-12.5 parts of trioctyl phosphate, and 0.65-0.95 parts of N-phenyl-α-aniline; The combination of expanded graphite, zinc oxide, alumina, nano-titanium nitride and N-phenyl-α-aniline, organic flame retardants and inorganic flame retardants are used together to produce a good synergistic effect, enhance the flame retardant effect, and resist The use of high temperature and flame retardant meets the actual requirements. At the same time, the combination of calcium carbonate powder, expandable graphite, zinc oxide and aluminum oxide makes the rubber sealing ring have a high elongation rate, and at the same time, it is convenient for quantitative cutting. |
