Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a highly stable modified water-based phenolic resin anticorrosion coating and its preparation method, and solves the problem that the phenolic resin is incompatible with water-based latex and cannot be well dispersed in water-based latex. In the emulsion, the problem of poor hydrophilicity of the anti-corrosion material is caused, and at the same time, it solves the unstable chemical properties of the phenolic resin. Body structure, leading to the loss of performance of phenolic resin anticorrosion materials

Abstract

The invention relates to the technical field of water-based phenolic resin anti-corrosion coatings, and discloses a highly stable modified water-based phenolic resin anti-corrosion coating and a preparation method thereof, comprising the following formula raw materials: phenolic resin, chitosan-L-aspartic acid Peptides, dispersants, inorganic fillers, molybdenum selenide, zinc oxide. The highly stable modified water-based phenolic resin anticorrosion coating and its preparation method, the chitosan contains a large number of hydrophilic hydroxyl groups, which improves the hydrophilicity of the phenolic resin and makes the phenolic resin and water-based emulsion compatible well Tolerance, evenly dispersed in water-based emulsion to form a water-based phenolic resin material, MoSe 2 It has good anti-corrosion performance, and the complex formed with ZnO has the performance of the anode of the electrochemical electrolytic cell. When the phenolic resin coating is applied to the hull of the ship, it consumes MoSe 2 ‑ZnO itself will generate a protective current and form a protective current loop in the electrolyte environment to achieve the effect of sacrificing the anode and protecting the cathode.

Description

technical field [0001] The invention relates to the technical field of water-based phenolic resin anti-corrosion coatings, in particular to a highly stable modified water-based phenolic resin anti-corrosion coating and a preparation method thereof. Background technique [0002] Metal corrosion is a phenomenon in which metal materials are damaged by the action of the surrounding medium. Metal corrosion is the most common form of corrosion. During corrosion, a chemical or electrochemical multiphase reaction occurs on the metal interface, causing the metal to turn into oxidation (ion) state, which 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, and deteriorate electrical and optical physical properties. [0003] Phenolic resin is mainly obtained by polycondensation of phenol aldehyde or its derivatives, which can be divided into two types: t...
