▎ 摘　　要

NOVELTY - Graphene composite polysulfide sealing agent comprises two components, which are polysulphide and vulcanization paste. The polysulphide paste is a liquid polysulfide rubber having average molecular weight of 1000-6000 and mole content of mercapto is 0.5-2%. The graphene is prepared by blending hmmers and treated ultrasonically to obtain graphene oxide. The carbonyl irons powder is spherical or sheet. The epoxy resin is grade E-44 and the mass ratio of polysulphide and vulcanized cream is 100:3-5. USE - Graphene composite polysulfide sealing agent. ADVANTAGE - The graphene composite polysulfide sealing agent has good radar absorbing sealant.
