Problems solved by technology

[0004] The technical problem mainly solved by the present invention is to provide a preparation of a graphene oxide anti-corrosion layer attached to the surface of iron in view of the disadvantages of current iron and metal equipment that are easy to corrode and cause product quality to decline, directly lead to economic damage, and waste pollutes the environment The method is to magnetize the composite particles made of oxidized graphene, zinc powder and nickel powder on the surface of the iron sheet, and then coat the iron surface with a layer of epoxy resin anticorrosion coating, which can effectively prevent water vapor, oxygen, ion and other penetration, greatly improving the chemical anti-corrosion performance of the metal

Embodiment Construction

[0022] Take 1.5~2g of prepared graphene oxide and ultrasonically disperse it in deionized water for 1.5~2h to obtain a uniformly dispersed graphene oxide suspension; add 3~5g of zinc powder and 1~2g of nickel powder into the already In the uniformly dispersed graphene oxide suspension, stir for 30-40 minutes to make the mixture uniform, then add 10mol / L ammonia water dropwise to the solution, stir while adding, and adjust the pH value of the solution to 6.0~ 7.0; Centrifuge the obtained product, remove the sediment from the lower layer and wash it with deionized water several times before centrifuging, remove the sediment from the lower layer and put it in an oven for drying, set the temperature at 80-90°C to obtain a composite oxidation Graphene / zinc / nickel particles; put the iron sheet into a mixed solution composed of absolute alcohol and pure acetone at a volume ratio of 1:1 and ultrasonically clean it for 10-15 minutes, take it out and clean it with deionized water, and th...

Abstract

The invention relates to a preparation method for an oxidized grapheme erosion-resistant coating attached to iron surface, and belongs to the field of metal material. The preparation method for the oxidized grapheme erosion-resistant coating attached to the iron surface is provided aiming at the disadvantages at present that equipment is corroded and damaged due to ferrous metal corrosion, product quality is reduced, and the environment is polluted, so that economy is damaged. According to the preparation method, composite particles are prepared from oxidized grapheme, zinc powders and nickel powders, then the composite particles are magnetized on the iron surface, and one layer of epoxy resin erosion-resistant coating is coated on the iron surface further. The preparation method can prevent the permeation of water vapor, oxygen, ion and the like, and chemical erosion-resistant performance of metal is improved greatly.

Description

technical field [0001] The invention relates to a preparation method of a graphene oxide anticorrosion layer attached to the surface of iron, belonging to the field of metal materials. Background technique [0002] Graphene oxide is the product of chemical oxidation of graphite powder. It is a new type of carbon material with excellent performance, which has a high specific surface area and abundant functional groups on the surface.
