Description

Technical Field

[0001] The invention relates to the technical field of lubricating oil, and in particular to a guide rail oil and a guide rail. Background Art

[0002] Guide rails, also known as slide rails, linear guide rails, and linear slide rails, are devices used to fix, bear, guide, move, and reduce friction. Industrial guide rails are mostly made of alloy steel, cast iron, or copper. For some guide rails that are larger in size and weight, the two metal surfaces that contact each other during use usually reciprocate under heavy loads. Therefore, during the use of the guide rails, the two contact surfaces often produce different degrees of cutting scratches and metal fatigue strain, causing damage; and the guide rails will generate a lot of heat when overcoming friction and moving, which will cause deformation, seriously affecting the accuracy of the equipment.

[0003] Therefore, when the guide rail is working, guide rail oil is added to lubricate the guide rail to prevent the guide rail from deformation or damage. However, the existing guide rail oil has the defects of poor anti-slip, anti-rust, anti-wear and anti-emulsification properties. Summary of the invention

[0004] The invention provides a guide rail oil, which has excellent anti-climbing, anti-rust, anti-wear and anti-emulsification properties.

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The first aspect of the present invention provides a guide rail oil, comprising, by mass percentage:

[0028]

[0029]

[0030] Wherein, the ionic liquid comprises the following structure:

[0031]

[0032] Wherein, n is a positive integer selected from 4-9.

[0033] The present invention does not limit the specific source of the ionic liquid. The ionic liquid can be prepared by a preparation method commonly used in the art, or it can be purchased commercially.

[0034] In the present invention, HVI400 and HVIH150BSM are both commonly used base oils in the art. The present invention does not particularly limit HVI400, HVIH150BSM, alkyl naphthalene, dithiophosphate acrylate, nonyl diphenylamine, sulfonated olefin cottonseed oil, barium dinonylnaphthalene sulfonate and polyisobutylene, and can be selected from HVI400, HVIH150BSM, alkyl naphthalene, dithiophosphate acrylate, nonyl diphenylamine, sulfonated olefin cottonseed oil, barium dinonylnaphthalene sulfonate and polyisobutylene commonly used in the art.

[0035] In the present invention, the guide rail oil includes the structure of Formula 1. On the one hand, the main component of the guide rail oil is the ionic liquid shown in Formula 1, so it can show excellent compatibility when combined with other components; on the other hand, the guide rail oil has excellent anti-climbing, anti-rust, anti-wear and anti-emulsification properties. Specifically, the ratio of the static friction coefficient to the dynamic friction coefficient is low. When the load carried by the guide rail containing the guide rail oil is too large and the speed changes greatly, the guide rail containing the guide rail oil will not produce boundary lubrication and mixed lubrication, and can prevent the guide rail from slipping; the guide rail oil can pass the gear test and viscosity performance test, and can run smoothly in low-speed and high-load heavy-duty machine tools and high-precision machine tool platforms.

[0036] At the same time, the ionic liquid does not contain sulfur and phosphorus elements. The use of the ionic liquid can reduce the content of sulfur and phosphorus elements in the guide rail oil as much as possible, so the environmental performance of the guide rail oil can be improved and industrial applications are convenient.

[0037] Further, based on the total mass of the guide rail oil, the mass percentage of the ionic liquid is 2-3%; and / or,

[0038] Based on the total mass of the guideway oil, the mass percentage of dithiophosphate acrylate is 2-3%; and / or,

[0039] When the mass percentage of polyisobutylene is 0.06-0.09% based on the total mass of the guide rail oil, the guide rail oil has more excellent anti-rust, anti-wear, anti-climbing and anti-emulsification properties.

[0040] In the present invention, the guide rail oil obtained by compounding dithiophosphate acrylate, ionic liquid, sulfurized olefin cottonseed oil, etc. can form a protective film on the surface of the guide rail, which can effectively protect the hydraulic system and metal parts in the guide rail, reduce the friction of the metal parts, and prevent the metal parts from rusting. In some embodiments of the present invention, in order to further improve the anti-rust and anti-climbing performance of the guide rail oil, the mass ratio of the ionic liquid to the dithiophosphate acrylate is 1:1.

[0041] In some embodiments of the present invention, in order to further improve the anti-rust, anti-wear, anti-climbing and anti-emulsification properties of the guide rail oil, the mass percentage of nonyldiphenylamine is 0.6-0.8% based on the total mass of the guide rail oil.

[0042] Furthermore, the purity of nonyldiphenylamine is greater than 99%. High-purity nonyldiphenylamine is beneficial to improving the purity of the guide rail oil and preventing the purity of the guide rail oil from being affected by impurities, thereby causing the color of the guide rail oil to deepen.

[0043] In some embodiments of the present invention, in order to improve the anti-wear property of the guideway oil under extreme pressure conditions and improve the odor of the guideway oil, the mass percentage of sulfurized olefin cottonseed oil is 0.4-0.6% based on the total mass of the guideway oil.

[0044] Furthermore, the mass percentage of sulfur in the sulfurized olefin cottonseed oil is less than 1%, which can better improve the odor of the guide rail oil and the anti-wear property of the guide rail oil under extreme pressure conditions.

[0045] In some embodiments of the present invention, the mass ratio of propylene dithiophosphate to sulphurized olefin cottonseed oil is 5: 1. When the mass ratio of propylene dithiophosphate to sulphurized olefin cottonseed oil is within the above range, not only can the guideway oil have suitable viscosity and better anti-wear performance under extreme pressure conditions, but also the odour of the guideway oil can be improved.

[0046] In some embodiments of the present invention, in order to further improve the anti-rust, anti-wear, anti-corrosion and anti-emulsification properties of the guide rail oil, the mass percentage of barium dinonylnaphthalenesulfonate is 0.02-0.08% based on the total mass of the guide rail oil.

[0047] In some embodiments of the present invention, when the molecular weight of polyisobutylene is greater than 30,000, the guide rail oil has a more suitable viscosity, which is more conducive to improving its anti-climbing and skidding performance. Further, the weight average molecular weight of polyisobutylene is greater than 30,000.

[0048] Furthermore, the structural formula of the ionic liquid is:

[0049] At the same time, the guide rail oil has better comprehensive performance (anti-climbing, anti-wear, anti-rust and anti-emulsification performance).

[0050] The guide rail oil in some embodiments of the present invention can be obtained by uniformly mixing the raw materials according to the above composition. The present invention does not specifically limit the order of adding the raw materials, the stirring rate, and the mixing temperature.

[0051] The guide rail oil of the present invention not only has relatively excellent anti-emulsification, anti-rust, anti-wear and anti-slip properties, but also has a simple preparation process, is easy to operate and has a wide range of applications.

[0052] A second aspect of the present invention provides a guide rail, which contains the above-mentioned guide rail oil.

[0053] The guide rail of the present invention, because it contains the above-mentioned guide rail oil, has relatively excellent anti-slip, anti-wear, anti-emulsification and anti-rust properties. When processing precision devices, it has high processing efficiency and high processing accuracy and has a wide range of applications.
