Problems solved by technology

The low-temperature index of the existing anti-rust oil for bearing storage, i.e. the freezing point, is generally around -10°C. When it is lower than -10°C, the fluidity of the anti-rust oil becomes poor, which cannot meet the requirements of lower ambient temperature in cold regions.

Embodiment 1

[0018] Take 2% of lanolin magnesium soap, 5% of calcium dinonyl naphthalene sulfonate, 6% of calcium petroleum sulfonate, 0.2% of polymethacrylate, and 86.8% of naphthenic transformer oil to prepare low-temperature antirust oil for bearing storage , its production process is as follows:

[0019] 1. Add 868Kg of naphthenic transformer oil into the reactor, stir, and heat to 110-120°C for full dehydration.

[0020] 2. When the temperature drops below 80°C, add 20Kg of lanolin magnesium soap, 50Kg of calcium dinonylnaphthalene sulfonate, and 60Kg of calcium petroleum sulfonate into the hot oil in the reactor, and stir to fully dissolve it.

[0021] 3. When the temperature drops to 60°C, add 2Kg polymethacrylate into the reaction kettle and stir to dissolve it completely.

[0022] 4. Stir constantly to mix all the materials evenly, and get low-temperature anti-rust oil after filtering out impurities.

Embodiment 2

[0024] Take 2.5% of lanolin magnesium soap, 4% of calcium dinonylnaphthalene sulfonate, 9% of calcium petroleum sulfonate, 0.4% of pour point depressant, and 84.1% of naphthenic hydraulic oil to prepare low-temperature antirust oil for bearing storage. The production process is as follows:

[0025] 1. Add 841Kg of naphthenic hydraulic oil into the reactor, stir, and heat to 110-120°C to fully dehydrate.

[0026] 2. When the temperature drops below 80°C, add 25Kg of lanolin magnesium soap, 40Kg of calcium dinonylnaphthalene sulfonate, and 90Kg of calcium petroleum sulfonate into the hot oil in the reactor, and stir to fully dissolve it.

[0027] 3. When the temperature drops to 60°C, add 4Kg of polymethacrylate into the reaction kettle and stir to dissolve it completely.

[0028] 4. Stir constantly to mix all the materials evenly, and get low-temperature anti-rust oil after filtering out impurities.

Embodiment 3

[0030] Take 3% of lanolin magnesium soap, 4% of calcium dinonylnaphthalene sulfonate, 8% of calcium petroleum sulfonate, 0.6% of pour point depressant, and 84.4% of naphthenic transformer oil to prepare low-temperature antirust oil for bearing storage. The production process is as follows:

[0031] 1. Add 844Kg of naphthenic transformer oil into the reactor, stir, and heat to 110-120°C for full dehydration.

[0032] 2. When the temperature drops below 80°C, add 30Kg of lanolin magnesium soap, 40Kg of calcium dinonylnaphthalene sulfonate, and 80Kg of calcium petroleum sulfonate into the hot oil in the reactor, and stir to fully dissolve it.

[0033] 3. When the temperature drops to 60°C, add 6Kg of polymethacrylate into the reaction kettle and stir to dissolve it completely.

[0034] 4. Stir constantly to mix all the materials evenly, and get low-temperature anti-rust oil after filtering out impurities.

Abstract

The invention relates to low-temperature antirust oil used in bearing sealing. The oil is composed of the components of, by weight: 13-17% of an antirust agent, 0.2-0.8% of a pour point depressant, and 82-87% of base oil. The antirust agent is composed of lanolin magnesium soap, calcium dinonyl naphthalene sulfonate, and calcium petroleum sulfonate. The pour point depressant is polymethacrylate. The base oil is polymethyl cycloalkyl transformer oil or hydraulic oil. The antirust oil provided by the invention has good low-temperature fluidity. Coagulation crack is prevented under low temperature. The base oil has low pour point. Especially, the pour point depressant is added, such that the pour point is lower. Therefore, the antirust oil can be used in an environment with a temperature of -10 DEG C and lower. Also, the antirust oil provided by the invention is clear and transparent, and has no precipitate or film. The oil has the advantages of good application performance, good oil film maintenance, simple production process, and convenient application. The process is mainly used in bearing antirust sealing under low temperatures, and can be applied on both open-type and sealed bearings. No adverse influence is caused on bearing lubricating grease. The antirust oil can also be used in sealing and rust prevention of other black metal products.

Description

technical field [0001] The invention relates to the technical field of anti-rust oil, in particular to a low-temperature anti-rust oil for bearing sealing and its production process. Background technique [0002] In order to meet the storage needs of product bearings, the finished bearings generally need anti-rust treatment. Anti-rust oil has the characteristics of easy-to-obtain materials, low cost, wide adaptability, and long anti-rust period. It is widely used in the bearing industry to seal and prevent rust on bearings. The prerequisite for bearing sealing and rust prevention is that the anti-rust oil must form a uniform and complete oil film on each surface of the bearing, and oil film defects are not allowed, otherwise, rust will first occur where the oil film is defective. Therefore, the antirust oil for bearing storage should have good fluidity, be able to cover all surfaces of the bearing smoothly, and form a continuous and uniform oil film. my country has a vast ...
