Oil membrane bearing oil composition and preparation method thereof

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...

Problems solved by technology

[0004] However, oil film bearings require high manufacturing precision, are expensive, and have extremely harsh operating conditions. Therefore, demanding performance requirements are imposed on oil film bearing oils. pollution

When the traditional oil film bearing oil is mixed with water and cannot be completely separated, due to the growth of bacteria, the oil will be corrupted and deteriorated, affecting the use effect, and will produce unpleasant odors, which will affect the working environment

[0005] The solution in the prior art is usually to add an antibacterial agent to the oil, but the oil system is complex, and the components have a great influence on each other. The introduction of the antibacterial agent is usually difficult to adapt to other components, and the antibacterial effect is poor, and It will also cause the reduction of other properties of the oil such as oxidation resistance, extreme pressure wear resistance, and anti-corrosion performance. Therefore, it is very difficult to develop an oil film bearing oil with excellent comprehensive performance. Rust and other properties are difficult to balance
