Abstract

The invention discloses nanofiber reinforced heavy anticorrosion coating and a preparation method thereof. The nanofiber reinforced heavy anticorrosion coating comprises epoxy resin, fiber, nanometerzinc powder, a curing agent, vinyl acetate and 650 low molecular polyamide. The preparation method comprises the following steps: preparing fiber mesh fabric, impregnating, and coating with epoxy resin coating. The invention has the beneficial effects as follows: a layer of fiber mesh fabric is added into the epoxy resin coating, and the nanometer zinc powder in fiber can increase the anticorrosion function of the coating itself; ethylenediamine impregnated into the fiber mesh fabric can quickly cure the epoxy resin to form a spatial network structure which can coat the fiber therein, so thatthe fiber mesh fabric and the epoxy resin are firmly combined; the 650 low molecular polyamide coating the fiber mesh fabric can slowly react with the epoxy resin on both sides of the fiber mesh fabric, so that the toughness of the epoxy resin around the fiber mesh fabric is improved, a defect of easy stress concentration on an interface between the fiber mesh fabric and the epoxy resin is eliminated, and the stability of overall mechanical properties of the coating is maintained.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a nanofiber-reinforced heavy-duty anti-corrosion coating and a preparation method thereof. Background technique [0002] Epoxy resin molecules contain active epoxy groups, which can cross-link with various types of curing agents to form insoluble polymers with a three-way network structure. Using this feature, epoxy resin can be used as a An important coating, epoxy resin coating has excellent bonding strength to the surface of the material, good dielectric properties, small deformation shrinkage, good dimensional stability, high hardness, good flexibility, stable to alkali and most solvents. Due to its dense spatial network structure, epoxy resin coatings have strong anti-corrosion ability. The anti-corrosion principle of epoxy resin is to coat the metal surface to isolate the oxidation of metal by oxygen. It itself does not have electrical conductivity or reduction properties...
