Abstract

The invention discloses a ZrO2-MWCNTs epoxy resin system composite material. The preparation method of the ZrO2-MWCNTs epoxy resin system composite material comprises the following steps: dissolving an epoxy resin system in an organic solvent, adding ZrO2-MWCNTs, stirring and uniformly mixing, performing ultrasonic dispersion for 30 min, and then uniformly spraying the mixture onto circular glass sheets, leaving to stand for 30 min at room temperature, baking for 1 h at 110 DEG C, and baking again for 1.5 h at 220 DEG C to obtain the ZrO2-MWCNTs epoxy resin system composite material. According to the preparation method of the ZrO2-MWCNTs epoxy resin system composite material, provided by the invention, multiwalled carbon nanotubes (MWCNTs) and zirconium dioxide (ZrO2) are combined to prepare the ZrO2-MWCNTs nano-hybrid material, and the ZrO2-MWCNTs nano-hybrid material is dispersed in the epoxy resin system by stirring and ultrasonic dispersion, so that the prepared ZrO2-MWCNTs epoxy resin system composite material is improved in toughness and corrosion resistance when being compared to epoxy resin, and is also obviously improved in abrasive resistance.

Description

technical field [0001] The invention belongs to the field of preparation of composite materials, in particular to a ZrO 2 -Preparation method of MWCNTs / epoxy resin system composite material. Background technique [0002] As a commonly used thermosetting plastic, epoxy resin has excellent mechanical properties, low shrinkage, chemical corrosion resistance and thermal stability, so it has been widely used in petroleum pipelines, cars, machinery and other fields. With the continuous expansion of its application fields, people put forward higher and higher requirements for the wear resistance of epoxy resin. However, due to the three-dimensional cross-network structure of epoxy resin in the curing process, its friction and wear properties poor. [0003] Carbon nanotubes (CNTs) have a very wide range of applications in many new fields such as nanoelectronic devices, super composite materials, hydrogen storage materials, and catalyst supports because of their unique structure, e...
