Abstract
The invention discloses high-strength bio-based epoxy resin capable of being recycled in a closed-loop mode and a preparation method, a recycling method and application of the high-strength bio-based epoxy resin capable of being recycled in the closed-loop mode. The preparation method comprises the steps that 1, a lignin acid alcohol compound, epoxy chloropropane and a catalyst are subjected to a ring-opening reaction, then alkali metal hydroxide is added for a cyclization reaction, and a compound A is obtained; a lignin acid alcohol epoxy compound is prepared; and 2, carrying out a curing reaction on the lignin acid alcohol epoxy compound obtained in the step 1 and an amino compound to obtain the high-strength bio-based epoxy resin capable of being subjected to closed-loop recovery. The epoxy resin material prepared by the invention is a novel green, degradable and reusable high polymer material, and can be applied to the fields of fiber modification, coatings, adhesives and the like.
