Abstract

The invention provides water soluble metal antirusting agent. The water soluble metal antirusting agent comprises the following constituents in part by mass: 7 to 10 parts of triethanolamine, 3 to 5 parts of zinc chloride, 2 to 3 parts of sodium borate, 1 to 2 parts of sodium methoxide, 4 to 6 parts of sodium carbonate, 3 to 5 parts of stannous mono-sulphate, 1 to 2 parts of diethanol amine, 1 to 2 parts of isopropyl alcohol, 10 to 15 parts of ethyl alcohol, and 70 to 80 parts of water. The invention further provides a preparation method of the antirusting agent. By soaking metal work pieces in the water soluble metal antirusting agent, a layer of oxide protective film can be formed on the surface of metal, the tissue structure is dense, and particles are fine, so that the effect of rust protection is achieved; the water soluble metal antirusting agent is short in film formation time and good in drying capacity, and can form a film in 1 to 2 minutes only; the water soluble metal antirusting agent can ensure that metal keeps rustless within 6 months in normal environment.

Description

technical field [0001] The invention relates to a water-soluble metal antirust agent. 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 water-soluble metal rust inhibitor. Therefore, the present invention also provides its preparation method. [0004] The invention provides a water-soluble metal antirust agent. The water-soluble...
