The invention discloses a biologic intrinsic flame-retardant epoxy monomer and a preparation method and application thereof, the structural formula of the biologic intrinsic flame-retardant epoxy monomer is shown in the specification, a Schiff base structure and an aromatic ether structure are introduced into the epoxy monomer, and-C = N-bonds in the Schiff base structure can generate self-crosslinking at high temperature to generate a carbon-nitrogen six-membered ring; the six-membered ring structure can enable the polymer to form a stable cross-linked network, and endows the high polymer material with excellent char forming and flame retardant properties; the aromatic ether structure is cracked and rearranged in the combustion process, and free radical fragments are captured, so that the formation of carbon layers with different conjugated aromatic structures is promoted, and the flame retardant property of the polymer is further improved; in addition, traditional flame-retardant elements such as halogen an
