Abstract

The invention provides anti-rust spraying fluid for metals, which is composed of the following components in parts by mass: 12-15 parts of triethanolamine, 4-5 parts of borax, 1-2 parts of sodium molybdate, 3-5 parts of sodium bisulfate, 1-2 parts of diethanolamine, 2-3 parts of isobutanol, 0.5-1 parts of isopropyl alcohol, 0.5-1 parts of sodium chloride, 8-12 parts of ethanol, and 85-95 parts of water. When the anti-rust spraying fluid for metals disclosed by the invention is splayed on a metal workpiece, an anti-oxidation protection film can be formed on the surface of the metal workpiece, and the film is compact in tissue structure and fine in particles, so that a rust protection effect is achieved; the anti-rust spraying fluid for metals disclosed by the invention is short in film-forming time and good in fast drying property, and can form a film in 2-3 minutes; and in a normal environment, metals can be prevented from rusting in 5-6 months.

Description

technical field [0001] The invention relates to a metal antirust spraying liquid. Background technique [0002] In metalworking processes, such as cutting and cold rolling, emulsions or fully synthetic cutting fluids are often used for cooling and lubrication. Due to the presence of large amounts of water in machining fluids, corrosion protection of surfaces during and after machining is critical. At present, antirust oil and antirust paint are mostly used for long-term antirust of metal processing or products, which have high cost and serious environmental pollution. It is difficult to treat waste liquid in the later stage, which brings a lot of inconvenience to use. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a metal antirust spraying liquid. [0004] The invention provides a metal antirust spraying liquid, which is composed of the following components in parts by mass: 12-15 parts of triethanolamine, 4-5 p...
