Abstract

The invention discloses a Fe2O3‑HNTs epoxy resin composite material, the preparation method of which comprises the following steps: (1) ultrasonically dispersing the Fe2O3‑HNTs hybrid material into a mixed solution of absolute ethanol and deionized water, and then adding KH560 ultrasonic Disperse, then transfer the mixed solution into a three-necked flask, reflux at 80°C, remove the unreacted KH560 silane coupling agent with methanol, and finally filter it with a filter membrane, dry it in vacuum and grind it for use; (2) Dissolve the curing agent and epoxy resin In an organic solvent, mix the Fe2O3-HNTs powder treated in step (1) with it, stir and mix it, and then ultrasonically disperse it, then place it at room temperature, bake at 110°C, and bake at 220°C to obtain Fe2O3-HNTs epoxy resin composite material. The Fe2O3-HNTs epoxy resin composite material prepared by the method has strong toughness and wear resistance.

Description

technical field [0001] The invention belongs to the field of preparation of composite materials, in particular to a Fe 2 o 3 -The preparation method of HNTs epoxy resin composite material. Background technique [0002] As a new type of inorganic nanomaterial, halloysite nanotubes (HNTs) have high specific surface area, strong thermal stability, abundant surface active groups, similar structure and morphology to carbon nanotubes, and good Biocompatibility, reproducibility, and excellent mechanical properties, it is a nanomaterial that can well replace carbon nanotubes and graphene. [0003] Epoxy resin (EP) has defects such as large internal stress, brittle texture, high crosslinking density, poor wear resistance, and many micropores formed due to solvent volatilization during the curing process. However, adding halloysite nanotubes to the epoxy resin can improve the thermal stability, toughness, impact strength, bending strength and other properties of the composite mater...
