Milky rust-proof liquid and preparation method thereof

Abstract

The invention provides a milky rust-proof liquid which comprises the following components in parts by weight: 10 to 30 parts of machine oil, 5 to 10 parts of barium petroleum sulfonate, 2 to 4 parts of iron naphthenate, 1 to 3 parts of fatty acid salt, 1 to 4 parts of sodium dodecyl benzene sulfonate, 2 to 5 parts of triethanolamine oleate, 2 to 6 parts of OP-10, 0.2 to 0.8 part of rosin resin, 0.1 to 0.5 part of polyacrylate, 1 to 3 parts of silicone oil and 10 to 15 parts of water. The milky rust-proof liquid provided by the invention has the advantages of long rust-proof life, good stability, nontoxicity, no abnormal odor, low cost and the like.

Description

technical field [0001] The invention belongs to the field of metal antirust, and in particular relates to an emulsion antirust liquid and a preparation method thereof. Background technique [0002] Cast iron is an alloy that is very easy to rust. The protection of cast iron from corrosion is the same as that of other alloys. Two liquids are often used: one is an aqueous solution containing oxidative corrosion inhibitors such as sodium nitrite; the other is an aqueous solution containing antirust Organic solution of oil. Although the cost of the former is low, but the use concentration is high, the anti-rust period is short, it must be soaked or sprayed regularly and the anti-rust agent is added, the workload is heavy, and the castings must be stored in a room with soaking pools or spraying facilities; although the latter is anti-corrosion The rust effect is good, and the operation is relatively simple, but because it contains a large amount of organic solvents, it has the d...

Problems solved by technology

Although the cost of the former is low, but the use concentration is high, the anti-rust period is short, it must be soaked or sprayed regularly and the anti-rust agent is added, the workload is heavy, and the castings must be stored in a room with soaking pools or spraying facilities; although the latter is anti-corrosion The rust effect is good, and the operation is relatively simple, but because it contains a large amount of organic solvents, it has the disadvantages of flammability, serious environmental pollution, and high cost.
