Bio-based bisphenol monomer containing fluorene ring structure, bio-based epoxy resin monomer, bio-based epoxy resin material and preparation methods thereof

The invention relates to a bio-based bisphenol monomer containing a fluorene ring structure, a bio-based epoxy resin monomer, a bio-based epoxy resin material and preparation methods thereof, and belongs to the technical field of high molecular material. The technical problems that an epoxy resin material in the prior art depends on petrochemical engineering resources and has potential toxicity are solved. The structural formula of the bio-based bisphenol monomer containing the fluorene ring structure is shown in the specification. The bio-based bisphenol monomer containing the fluorene ring structure takes a natural product guaiacol as a raw material and has relatively low estrogen activity. The bio-based epoxy resin monomer prepared from the raw material of the low-estrogen- activity bio-based bisphenol monomer containing the fluorene ring structure through a one-step method can effectively reduce the dependence of the epoxy resin material on petrochemical engineering, and reduce the potential toxicity of t
