NOVELTY - A bisphenol A synthetic composite resin catalyst comprises 30-90 %mass styrene based monomer (I), 1-30 %mass cross-linking agent, 0.1-20 %mass nanomaterials, and 8.0-25 %mass mercaptoalkyl quaternary ammonium salt. The cross-linking agent is at least one of divinylbenzene, divinyl phenyl methane, and dialkyl benzene. The nanomaterials are at least one of graphene, carbon nanotubes, and nano-silicon oxide. The mercaptoalkyl quaternary ammonium salt comprises N,N-dimethyl-N-ethyl-3-mercaptopropyl quaternary ammonium salt, N, N,N-trimethyl-3-mercaptopropyl quaternary ammonium salt, and N,N-dimethyl-N-propyl-3-mercaptopropyl quaternary ammonium salt. USE - Bisphenol A synthetic composite resin catalyst. ADVANTAGE - The composite resin catalyst has a stable structure, improves the shrinkage resistance of resin, and has high catalytic activity and selectivity at the same time.
