Abstract

The invention discloses special anti-rust oil for a zinc-aluminum-magnesium plate and a preparation method of the special anti-rust oil. The special anti-rust oil comprises the following raw materials in percentage by weight: 5-15% of a sulfonate and carboxylate mixture, 1-3% of sulfonate and carboxylic acid derivatives, 0.1-1% of lanolin fatty acid and polyol synthetic grease, 0.1-1% of a metal deactivator, 1-5% of fatty acid ester, 1-5% of a nonionic surfactant and the balance of synthetic mineral oil. The anti-rust oil disclosed by the invention has excellent water melting capacity, can be used for coating oil on a zinc-aluminum-magnesium steel plate in high-temperature and high-humidity weather, and can effectively inhibit color change of the zinc-aluminum-magnesium steel plate; the anti-rust oil has the characteristics of good atomization performance, excellent anti-rust performance, excellent lubricating performance, easiness in subsequent cleaning and the like. Oiled steel plates are free of discoloration, oil spots and corrosion after being placed for a long time, and are suitable for rust prevention of novel plates such as zinc-plated aluminum-magnesium plates.

Description

technical field [0001] The invention is applicable to the emerging technical field of plate protection such as galvanized aluminum-magnesium plates, and in particular relates to a special antirust oil for galvanized aluminum-magnesium plates and a preparation method thereof Background technique [0002] Aluminum-magnesium coating is an alloy metal with excellent comprehensive performance. The manufacturing cost is only slightly higher than that of aluminum-zinc coating. The weight of the coating is 700g / m2 on both sides, and red rust will appear after 4164-4074 hours in the neutral salt spray test). At the same time, the protection performance of the steel plate cut is very good, and the welding performance is equivalent to that of pure zinc steel plate. At present, zinc-aluminum-magnesium steel sheets have been directly applied in the market. At the same time, zinc-aluminum-magnesium color-coated sheets used as color substrates have also achieved mass production and a large...
