Abstract

The invention discloses long-acting antirust oil and a preparation method thereof. The long-acting antirust oil comprises the following components in parts by weight: 60-70 parts of base oil, 3-8 parts of petroleum barium sulfonate, 0.5-1 part of dodecenylsuccinic acid, 0.2-1 part of sorbitan monooleate, 2-6 parts of wool fat, 0.2-0.8 part of tert-butyl p-cresol, 0.5-1 part of benzotriazole, 0.5-1 part of stearic acid and 0.5-1 part of industrial lecithin. The preparation method comprises the steps of adding the base oil into a container, heating and then adding the petroleum barium sulfonate and the benzotriazole into the container; continuously heating and stirring to enable machine oil to be completely dehydrated; cooling and then adding the dodecenylsuccinic acid and the wool fat; stirring, dissolving and then continuously cooling; adding the rest components, and evenly stirring and mixing; filtering impurities to obtain the long-acting antirust oil. After a metal plate is treated by the long-acting antirust oil, a performance test is carried out on the metal plate, and the result proves that the long-acting antirust oil disclosed by the invention has the protection function for a long time.

Description

technical field [0001] The invention belongs to the field of antirust of metal materials, in particular to a long-acting antirust oil and a preparation method thereof. Background technique [0002] Corrosion is one of the main forms of fastener damage, and it will cause great losses to automobiles, motorcycles and various vehicles and machinery. According to statistics, the annual direct economic loss caused by metal corrosion accounts for about 2%-4% of the country's total economic output value. [0003] In order to avoid corrosion and reduce losses, people have adopted various methods, and using antirust grease to protect metal fasteners is one of the most common protection methods at present. [0004] Among the temporary protection methods, anti-rust oil plays a very important role. Different types of antirust oils have different uses. With the development of industry, the types of metal products continue to increase, and there are more and more cases of harsh corrosio...
