Abstract

The invention relates to a novel black metal antirust agent and a preparation method thereof. The metal antirust agent comprises, by weight, 2%-10% of sodium nitrite, 5%-15% of sodium silicate, 1%-5% of sodium tripolyphosphate, 5%-10% of benzotriazole, 8%-15% of triethanolamine oleate, 1%-8% of cyclohexylamine carbonate, 5%-15% of urotropine and 30%-70% of deionized water. The black metal antirust agent is excellent in performance, high in anti-rust property, low in cost, convenient to operate, capable of not damaging the original color and luster of the surface of a machine part, and high in rust preventing and membrane forming speed, thereby being an effect optimum product for medium-short-term rust prevention.

Description

technical field [0001] The invention relates to the technical field of antirust, in particular to a novel ferrous metal antirust agent and a preparation method thereof. Background technique [0002] Ferrous metal plays a very important role in modern industrial and agricultural production and life, but metal will suffer from different forms of damage due to the influence of the surrounding environment during its use, the most common of which is rust. In order to prevent the metal surface from rusting, antirust treatment must be carried out, such as applying an antirust agent on the surface. The traditional anti-rust method for metal surfaces is to use anti-rust oil with better anti-rust effect, and form a protective oil film on the metal surface through the anti-rust oil to isolate the corrosion of the metal by the surrounding environment medium, so as to achieve long-term anti-rust. However, the use of anti-rust oil not only consumes a large amount of oil raw materials, bu...
