Abstract

The invention discloses a humidity-heat-resistant long-acting anticorrosion coating. The coating is prepared from, by weight, 30-45 parts of novolac epoxy, 5-15 parts of bisphenol A type epoxy resin, 5-20 parts of iron oxide red, 2-15 parts of aluminum triphosphate, 5-20 parts of talcum powder, 5-20 parts of barium sulfate, 0.1-1 part of coupling agent, 0.1-1 part of defoaming agent, 0.1-2 parts of dioctyl phthalate, 15-60 parts of solvent and 7-22 parts of curing agent. The coating is good in acid and base resistance, heat resistance and solvent resistance, convenient to construct and capable of being widely used for long-acting corrosion prevention of metal structural parts in the hygrothermal environment.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a long-lasting anti-corrosion coating that is resistant to humidity and heat, which is a long-lasting anti-corrosion coating used in a humid and hot environment. Background technique [0002] The corrosion rate of metal structural parts increases sharply in a hot and humid environment. In order to inhibit the corrosion, anticorrosive coatings are usually applied on the surface of metal structural parts. Epoxy resin coatings are the most widely used heavy-duty coatings, and bisphenol A epoxy resins are generally used as the base material of the coating. However, when the epoxy resin coating is in a hot and humid environment, due to its poor high temperature resistance, the service life of the coating will be significantly reduced, especially when the epoxy resin coating is in an acidic environment, its service life is even sharper reduce. Therefore, long-lasting anticorr...
