Abstract

The invention relates to water-based salt spray resistant gold oil and a preparation method thereof. The water-based salt spray resistant gold oil comprises the following components in parts by mass:40-50 parts of a water-based epoxy resin, 4-5 parts of a water-based epoxy curing agent, 50-60 parts of zinc powder, 2-5 parts of graphene oxide, 10-15 parts of rust-proof pigments and fillers, 3-5 parts of mica powder, 0.2-0.4 part of a dispersing agent, 4-6 parts of an adhesion promoter, 1-2 parts of an anti-scratch corrosion additive, 0.2-0.4 part of a water-based leveling agent, 0.3-0.5 part of a water-based antifoaming agent and 20-25 parts of deionized water. By improving the salt spray resistance of the water-based gold oil, the film sprayed onto protective metals is difficult to blister and drop, and the protection property of metals is prolonged.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based salt-spray resistant gold oil and a preparation method thereof. Background technique [0002] In my country, more than 100 million tons of metals are scrapped due to corrosion and rust every year, which brings huge economic losses. With the rapid development of the marine industry, the number of offshore oil production platforms, offshore bridges, submarine tunnels and other infrastructure is increasing. Seawater has high salt content and good electrical conductivity. Metals with different activities will accelerate corrosion when they come into contact with more active metals. Coating protection is the main method of corrosion protection at present. Spraying metal with paint to prevent metal corrosion and rust is simple, economical and effective. At present, the development of oil-based anti-corrosion coatings is relatively mature, but the oil-based system contai...
