NOVELTY - An easily activated non-evapotranspiration type zirconium graphite getter material comprises zirconium/graphene composite material, titanium powder and molybdenum, where the zirconium/graphene composite material is prepared by (S1), adding graphene oxide to ultra-pure water, stirring, adding sodium hydroxide aqueous solution to adjust pH to 8, adding 10% sodium dodecyl sulfate aqueous solution and vitamin C powder, stirring, adding precursor solution to foam, stirring and foaming, adding formed foam to reaction kettle, stirring and adding zirconium reagent, drying and stirring for 1 hour to obtain hydrogel, (S2) freezing hydrogel at -20degreesC for 4 hours, taking out and thawing, again adding to reaction kettle, heating at 90degreesC, stirring and reacting to obtain product (I), soaking the primary product in 90% ethanol aqueous solution for dialysis until the solution is clear and transparent, continuously placing in refrigerator at -20degreesC and freezing for 4 hours. USE - Easily activated non-evapotranspiration type zirconium graphite getter material for cathode of vacuum electronic component e.g. travelling wave tube, X-ray tube and infrared chip. ADVANTAGE - The zirconium graphite getter material is graphene aerogel doped with zirconium powder, which is porous three-dimensional structure, with ultra-high specific surface area, and when mixed with other raw materials such as titanium powder, the nano-grade metal powder enter into the hole, forming stable and uniform system, and the titanium powder and molybdenum are sintered to form getter alloy material, thereby increasing the porosity of substrate, forming larger channel, and improving the air suction performance. DETAILED DESCRIPTION - The easily activated non-evapotranspiration type zirconium graphite getter material comprises 50-70 pts. wt. zirconium/graphene composite material, 15-25 pts. wt. titanium powder and 5-8 pts. wt. molybdenum, where the zirconium/graphene composite material is prepared by (S1), adding graphene oxide to ultra-pure water, stirring at constant speed for 15 minutes to form dispersion, adding 15% sodium hydroxide aqueous solution to adjust pH to 8, adding 10% sodium dodecyl sulfate aqueous solution and vitamin C powder, stirring at high speed until generating foam, continuously stirring for 10 minutes, stopping stirring, adding precursor solution to foam, quickly stirring and foaming for 30 seconds, adding formed foam to reaction kettle, stirring at high speed and adding zirconium reagent, drying at 75degreesC and continuously stirring for 1 hour to obtain hydrogel, (S2) freezing hydrogel at -20degreesC for 4 hours, taking out and thawing, again adding to reaction kettle, heating at 90degreesC, stirring at uniform speed and reacting for 6 hours to obtain product (I), soaking the primary product in 90% ethanol aqueous solution for dialysis until the solution is clear and transparent, continuously placing in refrigerator at -20degreesC and freezing for 4 hours.
