Example Embodiment

[0045] Example 1: An anti-rust oil, the components and their corresponding parts by weight are shown in Table 1, and are prepared through the following steps:

[0046] (1) Add dodecenyl succinic acid and barium petroleum sulfonate to the engine oil at the same time, then stir for 2 hours, then add triethanolamine and heat to 50°C, stir and dissolve for 2 hours;

[0047] (2) Add palmitic acid to the emulsification system of step (1), heat to 40°C, stir for 1 hour, then add sodium dodecylbenzene sulfonate, and stir evenly;

[0048] (3) Add water and a buffer solution to the emulsification system of step (2), stir for 1 hour, add 4-methylbenzotriazole, and stir for another 2 hours to obtain an anti-rust oil.

[0049] The buffer solution is a mixture of sodium carbonate and sodium bicarbonate, and the pH is controlled between 10-11.5.

Example Embodiment

[0050] Example 2-6: An anti-rust oil. The difference from Example 1 is that the components and their corresponding parts by weight are shown in Table 1.

Example Embodiment

[0054] Example 7: A preparation method of anti-rust oil. The difference from Example 1 is that 10 parts of antibacterial agent are added in step (3), and the antibacterial agent is obtained by the following preparation steps:

[0055] Add 1g of carboxymethyl chitosan to 250mL of deionized water, stir evenly, add 250mL of silver nitrate solution with a concentration of 2mmol / L, stir and heat to 60℃, react for 1h and then cool to 25℃, and add dropwise concentration of 1mmol / L L sodium borohydride solution was stirred and reacted for 0.5h to obtain an antibacterial agent.

Abstract

The invention discloses antirust oil and a preparation method thereof, and relates to the technical field of metal rust prevention, wherein the antirust oil comprises, by weight, 5-10 parts of dodecenylsuccinic acid, 50-60 parts of barium petroleum sulfonate, 15-30 parts of triethanolamine, 150-200 parts of engine oil, 45-60 parts of palmitic acid, 10-20 parts of 4-methylbenzotriazole, 30-50 partsof sodium dodecyl benzene sulfonate, 45-60 parts of a buffer solution, and 600-700 parts of water. According to the invention, the anti-rust oil prepared by the formula has advantages of good anti-rust performance and low use cost.

Description

technical field [0001] The invention relates to the technical field of metal antirust, more specifically, it relates to an antirust oil and a preparation method thereof. Background technique [0002] Corrosion is one of the main forms of damage to fasteners, and it will cause great losses to automobiles, motorcycles and various vehicles and machinery. In order to avoid corrosion of metal parts such as fasteners and reduce the loss caused by it, people have adopted various methods, such as electroplating, hot-dip galvanizing, etc. [0003] Nowadays, most fasteners often use electroplating process for anti-rust, which has good anti-rust effect, but also has great disadvantages, such as high energy consumption of electroplating, large pollution of electroplating waste liquid, and high cost of waste liquid treatment This leads to the high cost of electroplated fasteners, and often due to its high energy consumption and high pollution, many fastener manufacturers do not have the...
