▎ 摘  要

NOVELTY - Long-life dental plate reinforced high-strength graphite gasket comprises an annular graphite plate and a metal punching plate embedded in the middle of the annular graphite plate. The annular graphite plate comprises 100 pts. wt. flexible graphite powder, 3-5 pts. wt. coupling agent, 3-7 pts. wt. boron nitride fiber, 5-8 pts. wt. nanoboron fiber, 3-6 pts. wt. graphene fluoride, 4-6 pts. wt. sulfonated polyphenylene sulfide, 7-12 pts. wt. N-(4-cyano-3-trifluoromethylphenyl)methacrylamide/allyltriphenylphosphine bromide/methylvinylsilicon fluorene/glycidyl methacrylate copolymer, 1-3 pts. wt. 2,2-bis(3-amino-4-hydroxyphenyl)hexafluoropropane, 1-2 pts. wt. phosphorus pentoxide and 0.6-1 pts. wt. polyphosphoric acid. USE - The gasket is useful in communication, traffic, aviation, and military electronic product. ADVANTAGE - The gasket: has good anti-aging performance, performance stability, high strength, good oxidation resistance, corrosion resistance, high and low temperature resistance, elastic foot, and long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the long-life dental plate reinforced high-strength graphite gasket comprising uniformly mixing the raw materials, adding into a crusher to crush, sieving by 200-200 meshes sieve to obtain the mixed material, placing the metal punching plate in the mold, pouring the mixed material into the two sides of the metal punching tooth plate for tableting, punching and forming, processing for 2-3 hours at 180-200degrees Celsius, cooling to room temperature, soaking in 50-60degrees Celsius water for 8-10 hours, taking out, placing in the vacuum drier, drying and obtaining the long-life dental plate reinforced high-strength graphite gasket
