Abstract

The invention discloses an antirust agent of a steel part and a preparation method. The antirust agent is prepared from the following raw materials in parts by weight: 20 to 30 parts of sodium hydroxide, 15 to 25 parts of oily wax, 10 to 18 parts of vaseline, 5 to 9 parts of triethanolamine, 40 to 55 parts of polyethylene glycol, 1 to 5 parts of sodium metaphosphate, 12 to 20 parts of sodium dodecyl sulfate, 8 to 15 parts of zinc oxide, 12 to 20 parts of glycerinum, 6 to 12 parts of ammonium molybdate and 300 to 500 parts of water. The antirust agent has the characteristics of having a small pungent smell and being long in shelf life.

Description

technical field [0001] The invention relates to an antirust agent, in particular to an antirust agent for steel parts and a preparation method thereof. Background technique [0002] Corrosion is an electrochemical process in which oxygen and water act on the surface of a metal (such as steel) to form a mixture of oxides and / or hydroxides. Corrosion is extremely harmful to the performance and service life of metal products, especially in special working environments, the corrosion speed is faster, causing huge losses. In order to solve the above problems, some chemical antirust agents are often used to coat the surface of steel parts to prevent surface oxidation and prolong the service life of steel parts. However, the current antirust agents have the following disadvantages: volatile components such as gasoline are used in the antirust agents on the market, which have a very pungent smell, and due to volatilization, the antirust agents are unstable and difficult to store. ...
