Corrosion-resistant and wear-resistant epoxy coating and preparation method thereof

The invention discloses a corrosion-resistant and wear-resistant epoxy coating which is prepared from the following raw materials in parts by mass: 1-5 parts of carbon nanotubes, 5-10 parts of short carbon fibers, 10-20 parts of silicon carbide powder, 80-150 parts of a dimethylformamide solvent, 100-200 parts of epoxy resin, 100-200 parts of a curing agent and 1-2 parts of a flatting agent. The invention further discloses a preparation method of the corrosion-resistant and wear-resistant epoxy coating. The preparation method comprises the following steps: carrying out surface modification on the carbon nanotubes, the silicon carbide and the short carbon fibers; preparing a carbon nanotube/short carbon fiber/silicon carbide composite modified epoxy coating; and preparing the corrosion-resistant and wear-resistant epoxy coating by using the composite modified epoxy coating. The epoxy coating prepared by the method has corrosion resistance, wear resistance, crack resistance and the like, the service life of the
