Problems solved by technology

At present, there are many types of antirust oil products on the market, including dehydration antirust oil, solvent soft film antirust oil, colored hard film antirust oil, shock absorbing antirust oil, etc., but the antirust period of these antirust oils is short, generally After the carbon steel material is treated with this kind of anti-rust oil, its anti-rust period is only one month

Embodiment 1

[0046]

[0047] Weigh the heat-conducting oil and pour it into the reactor and stir. Heat to 120℃. After dehydration, add the rust inhibitors sodium benzoate and calcium stearate. Keep it at this temperature and stir for 2 hours, then cool to 70℃ (i.e. natural After cooling by air, add barium dinonylnaphthalene sulfonate, dodecenyl succinic acid, and magnesium lanolin soap. After stirring for 1 hour, cool to 60°C (that is, naturally cooled by air) and add benzene- 80. Keep stirring to mix all the materials uniformly, keep stirring and lower the temperature to 50°C (that is, naturally cool by air), and get the anti-rust oil after filtering out the impurities. When in use, the carbon steel material is degreasing, decontamination, and drying, and then spraying the anti-rust oil evenly and thinly on the surface of the carbon steel material by using electrostatic spraying equipment.

Embodiment 2

[0049]

[0050] Weigh the heat-conducting oil and pour it into the reactor and stir, heat to 130℃, add rust inhibitor sodium benzoate and calcium stearate after dehydration, keep it warm and stir for 2 hours at this temperature, and cool to 80℃ (i.e. natural After cooling by air, add barium dinonylnaphthalene sulfonate, dodecenyl succinic acid, and magnesium lanolin soap. After stirring for 1 hour, the temperature is cooled to 65°C (that is, naturally cooled by air), and then benzene- 80. Keep stirring to mix all the materials uniformly, keep stirring and lower the temperature to 45°C (that is, naturally cool by air), and get the anti-rust oil after filtering out the impurities. When in use, the carbon steel material is degreasing, decontamination, and drying, and then spraying the anti-rust oil evenly and thinly on the surface of the carbon steel material by using electrostatic spraying equipment.

Embodiment 3

[0052]

[0053] Weigh the heat-conducting oil and pour it into the reactor and stir, heat to 125℃, add rust inhibitor sodium benzoate and calcium stearate after dehydration, keep it warm and stir for 3 hours at this temperature, and cool to 75℃ (i.e. natural After cooling by air, add barium dinonylnaphthalene sulfonate, dodecenyl succinic acid, and magnesium lanolin soap. After stirring for 2 hours, the temperature is cooled to 55°C (that is, naturally cooled by air) and then benzene- 80. Stir constantly to mix all the materials uniformly, keep stirring and lower the temperature to 40℃ (that is, naturally cool by air), and get the anti-rust oil after filtering out the impurities. When in use, the carbon steel material is degreasing, decontamination, and drying, and then spraying the anti-rust oil evenly and thinly on the surface of the carbon steel material by using electrostatic spraying equipment.

Abstract

The invention discloses a carbon steel material rust-preventative oil and a preparation method thereof. The carbon steel material rust-preventative oil comprises 90-95 parts of conduction oil, 0.5-1 part of calcium stearate, 0.6-0.8 part of sodium benzoate, 2-3 parts of dinonynalphthalene sulfonic acid barium, 0.4-0.6 part of dodecenylsuccinic acid, 1-1.5 parts of sorbitan monooleate, and 0.5-1 part of lanolin magnesium soap. When in use, the rust-preventative oil is sprayed on the surfaces of carbon steel materials by electrostatic spraying equipment. According to the technical scheme of the carbon steel material rust-preventative oil and the preparation method thereof which are disclosed by the invention, the rust-proof life is long, the binding capacity is good and the rust-proof effect is good.

Description

Technical field [0001] The invention relates to an anti-rust oil, in particular, to an anti-rust oil used to enhance the corrosion resistance of carbon steel materials and a preparation method thereof. Background technique [0002] According to statistics, the steel products that cannot be used due to corrosion and rust every year in the world are about 10%-20% of the annual output of steel. Metal corrosion can cause increased maintenance of machinery and equipment and early replacement of parts and components, while corrosion of metal products reduces the accuracy and sensitivity of the equipment, affects the use of the equipment, and even causes the equipment to be scrapped. With the accelerating process of economic globalization, Chinese companies are facing huge business opportunities in both domestic and foreign markets, bringing unprecedented development opportunities to my country’s manufacturing equipment industry, but the problem of metal corrosion has always plagued the...
