Abstract
The invention provides a water-based metalrust inhibitor. The water-based metalrust inhibitor comprises the following components in parts by weight: 10-14 parts of triethanolamine, 2-3 parts of aluminum oxide, 5-8 parts of sodiumsulfate, 1-2 parts of borax, 2-3 parts of boric acid, 1-2 parts of sodiummolybdate, 4-6 parts of sodiumcarbonate, 3-5 parts of isopropanol, 10-15 parts of ethanol and 80-90 parts of water. The invention further provides a preparation method of the rust inhibitor. A layer of oxidation protective film can be formed on the surface of a metal by soaking a metal workpiece in the water-based metal rust inhibitor provided by the invention, the structure is compact and particles are fine, so that an anti-rust effect is achieved; the water-based metal rust inhibitor provided by the invention has the advantages of short film-forming time and good quick-drying property, and the film can be formed within 1-2min; in a normal environment, the metal does not rust within 5-6 months by using the water-based metal rust inhibitor.
Description
technical field [0001] The invention relates to a water-based 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, anti-rust oil and anti-rust paint are mostly used for long-term anti-rust of metal processing or products. The cost is high, the environmental pollution is serious, and the waste liquid treatment is difficult in the later stage, which brings a lot of inconvenience to the use. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a water-based metal antirust agent. Therefore, the present invention also provides its preparation method. [0004] The invention provides a water-based metal antirust agent, which is c...
