[0048] The present invention also provides a method for preparing the oil film bearing oil composition described in the above technical solution, comprising:
[0049] After the base oil is heated and dehydrated, the temperature is lowered to 60-80° C., a viscosity improver, a bactericide, an antioxidant, an extreme pressure anti-wear agent, an anti-emulsifier and an anti-rust agent are added and mixed evenly to obtain an oil film bearing oil composition.
[0050] Wherein, the types, dosages and sources of base oils, viscosity modifiers, bactericides, antioxidants, extreme pressure antiwear agents, anti-emulsifiers and antirust agents are all consistent with those described in the above technical solutions, and will not be repeated here. A repeat. The heating temperature is preferably 110-130°C, more preferably 120°C. After rising to the target temperature, it is preferably kept for 1 hour.
Embodiment 1
[0053] Raw materials: 10 parts of base oil HVIⅠ150, 87.23 parts of base oil HVIⅠ650, 0.1 part of fungicide N-octadecyl-γ-diquaternary ammonium salt, 1.5 parts of extreme pressure and antiwear agent T306, 10.05 parts of anti-emulsifier T100, Rust agent T746 0.1 part, viscosity improver T801 0.5 part, antifoaming agent T921 0.02 part, antioxidant T531 0.5 part.
[0054] Preparation: Heat up the base oil to 120°C to remove water, then cool down to 70°C, add other raw materials and mix well to obtain oil film bearing oil.

Abstract
The invention provides an oil membrane bearing oil composition and a preparation method thereof. The oil membrane bearing oil composition provided by the invention comprises the following components:94.7-98.76 parts of basic oil, 0.01-1 part of a sterilization agent, 0.01-0.1 part of a demulsifying agent, 1-2 parts of an extreme pressure anti-wear reagent, 0.1-1 part of a viscosity improver, 0.1-1 part of an antioxidant, 0.01-0.1 part of an anti-rusting agent and 0.01-0.1 part of an anti-foaming agent, wherein the basic oil is selected from one or more of HVII basic oil and HVIII basic oil; the sterilization agent is selected one or more of isothiazolinone and quaternary ammonium salt; the demulsifying agent is selected from one or more of a condensation compound of amino and ethylene oxide and gylcol ester; the extreme pressure anti-wear reagent is selected from one or more of a sulfur-containing extreme pressure anti-wear reagent and a phosphorus containing extreme pressure anti-wear reagent. The bearing oil is not only excellent in antibacterial agent, but also excellent in oxidation resistance, extreme pressure wearing resistance and anti-rusting corrosion resistance, and is capable of well meeting use requirements of an oil membrane bearing.
Description
technical field [0001] The invention relates to the technical field of bearing oil, in particular to an oil film bearing oil composition and a preparation method thereof. Background technique [0002] With the rapid development of the metallurgical industry in the world, machinery such as high-speed rolling mills for steel plates and bars and Morgan twist-free high-speed wire rolling mills are widely used. Since my country introduced the first high-speed rolling mill in 1980, the rolling mill has been developing towards high speed, heavy load, and large-scale. [0003] As the "heart" of the rolling mill, the oil film bearing of the rolling mill is generally used as the support of the roll, and the oil film bearing oil can balance the load, isolate the journal and the shaft sleeve, convert the solid friction between the metals into the molecular friction inside the liquid, and reduce the friction and wear. Therefore, it is very critical for the oil film bearing system to mee...
