Multifunctional epoxy corrosion-resistant coating

Abstract

The invention discloses a multifunctional epoxy corrosion-resistant coating which is prepared by mixing epoxy resin, a solvent, a pigment filler, a curing agent, an aid and other components. The multifunctional epoxy anticorrosive coating has the benefits that the bottom and surface combination is realized, so that the working efficiency is improved; low surface treatment is performed, so that the pretreatment intensity is reduced, and particularly, the unique advantages are realized at some parts inconvenient to treat and engineering and under the environment with larger humidity; the coating is good in storage stability, high in one-time coating film thickness and good in sag resistance; the low-temperature curability is good, so that low-temperature (10 DEG C below zero) curing is realized; the long-term corrosion resistance and the salt fog resistance are equivalent to those of a epoxy zinc rich primer; meanwhile, the defects of poor zinc rich coating compactness and zinc layer acid and alkali resistance are overcome, and the duration of the resistance to acid, alkali and salt with a respective concentration of 5 percent can reach above one month.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a multifunctional epoxy anticorrosion coating. Background technique [0002] As a simple and effective method of material protection and decoration, paint coating has been widely used. With the development of modern society, higher requirements are put forward for the anti-corrosion properties of coatings, especially in facilities such as steel structure workshops, large-scale machinery and chemical equipment, which require the use of heavy-duty anti-corrosion coatings for protection. In order to obtain a good anti-corrosion effect, strict surface treatment must be carried out on the substrate before painting, and it is generally necessary to use a primer, a primer, a topcoat, or a primer and a topcoat. The quantity is large, the process is complicated, and the interval time is long. In addition, most of the traditional paints add toxic pigments and fillers, organic solvents, etc., whic...
