Abstract

The invention discloses a preparation method of a quick-drying type metal anti-corrosion coating. The preparation method of the quick-drying type metal anti-corrosion coating belongs to the technicalfield of coating preparation. Although the content of epoxidized soybean oil is less in the metal anti-corrosion coating, the activity of the epoxidized soybean oil is higher when reacting with maleicanhydride, so that the curing time of the metal anti-corrosion coating is shortened; a pre-mixed solution is used as a mixed monomer of an acrylic resin so as to be doped into dissolved epoxy resin,and a composite resin emulsion is obtained through grafting reaction; when the metal anti-corrosion coating is cured, hydrophobic substances in a micelle can be gathered and arrayed on a surface of apaint film, so that surface hydrophobicity of the metal anti-corrosion coating is improved; essential oil in an essential oil microcapsule has high volatility, can be slowly released from the microcapsule, and then is micro-emulsified in water of the metal anti-corrosion coating, so that drops of water become smaller, and water is convenient to volatize; the hydrophobicity of the essential oil isalso beneficial to water volatilization in the metal anti-corrosion coating, so that when the metal anti-corrosion coating is cured, the surface drying time is shorted, the aim of quick drying is achieved, and the application prospect is broad.

Description

technical field [0001] The invention discloses a preparation method of a quick-drying metal anticorrosion coating, which belongs to the technical field of coating preparation. Background technique [0002] Metal materials are damaged by the action of the surrounding medium, which is called metal corrosion. During corrosion, a chemical or electrochemical multiphase reaction occurs at the interface of the metal, which turns the metal into an oxidized state. This will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, increase wear between parts, deteriorate electrical and optical physical properties, shorten the service life of equipment, and even cause disasters such as fire and explosion. sex accident. Metal corrosion coatings have excellent rust resistance and chemical medium corrosion resistance, strong wear resistance, fresh water resistance, sea water resistance, salt ...
