Abstract

This invention discloses a method for preparing MXene / Fe3O4 / HBPB synergistically reinforced epoxy resin composites. Specifically, the method involves: preparing a few-layer MXene dispersion and MXene / Fe3O4 powder; preparing hydroxyl-terminated HBPB using borate ester monomers and diol monomers; adding the acetone dispersion of MXene / Fe3O4, the hydroxyl-terminated HBPB, and a reinforcing agent to a prepolymer of epoxy resin and curing agent DDS; and preparing the synergistically reinforced epoxy resin composite through a melt blending process combined with a staged temperature-curing method. This method combines the low-friction properties of MXene with the high load-bearing capacity of Fe3O4, achieving a synergistic lubrication effect that reduces friction and wear. HBPB can form bonds with the lubricating filler and epoxy resin, acting as a bridge and effectively enhancing interfacial bonding and compatibility, ultimately resulting in a high-strength, low-friction, and highly wear-resistant epoxy composite.
