Embodiment 1
[0032] The waterborne epoxy resin anticorrosion coating of the present embodiment is made up of each component of following mass percentage:
[0033] Silicone modified water-based epoxy resin dispersion 40%, iron oxide red 15%, anti-rust pigment titanium iron powder 8%, talcum powder 15%, defoamer 0.2%, leveling agent 0.2%, anti-flash rust agent Phosphate mixture 0.4%, deionized water 21.2%. The mass percentage is the percentage of the total mass of the coating taken by weighing.
[0034] Wherein the preparation method of siloxane modified aqueous epoxy resin dispersion liquid, its detailed steps are as follows:
[0035] (1) take by weighing each monomer and initiator of following mass percent: methacrylic acid 24%, methyl methacrylate 38%, styrene 36%, benzoyl peroxide 2%; Described mass percent is accounted for all Take the percentage of total monomer mass;
[0036] (2) In a four-necked flask equipped with agitator, condensing tube, nitrogen conduit, dropping funnel, pre-...
