Description

Technical field [0001] The invention relates to the technical field of anticorrosive coatings, in particular to a high-adhesion, high-temperature, wear-resistant and anticorrosive coating. Background technique [0002] In industrial production, the outer surface of metal structural parts, engineering machinery exhaust pipes, and metal structure high-temperature chimneys are often exposed to high-temperature gas, moisture and smoke for many years, and they are very easy to corrode, that is, chemical or electrochemical processes occur on the metal interface. Instead, turn the metal into an oxidized state, thereby significantly reducing the strength, plasticity, toughness and other mechanical properties of the metal material, destroying the geometric shape of the metal component, increasing the wear between metal deconstruction, shortening the service life of the equipment, and even causing fire and explosion And other catastrophic accidents, and the anti-corrosion coating is the si...

Problems solved by technology

[0002] In industrial production, the outer surfaces of metal structural parts, engineering machinery exhaust pipes, and metal structure high-temperature chimneys are often exposed to high-temperature gas, moisture, and smoke for many years, and are easily corroded, that is, chemical or electrochemical events occur on the metal interface. The opposite reaction turns the metal into an oxidized state, thereby significantly reducing the mechanical properties of the metal material such as strength, plasticity, and toughness, destroying the geometry of the metal component, increasing the wear between metal deconstruction, shortening the service life of the equipment, and even causing fire and explosion. and other catastrophic accidents, and anti-corrosion coatings are the simplest, low-cost and best material to protect metal components from corrosion. Since anti-corrosion coatings isolate metal components from the external environment, anti-corrosion coatings are required to have extremely high adhesion, high temperature resistance and Wear resistance, which is difficult for ordinary anti-corrosion coatings
