Description
Technical Field
The invention belongs to the technical field of lubricating oil, and particularly relates to a boronized rare earth lubricating oil additive and a preparation method thereof.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
With the development of modern mechanical equipment in the directions of high speed, high load, high temperature and the like, the lubricating condition of the equipment becomes more and more severe; at the moment, the lubricating oil film is difficult to bear all loads, a part of loads are directly borne by a friction surface, equipment is often in a boundary lubrication state, and correspondingly, a novel high-performance lubricating oil additive (the mass fraction is 1-2%) must be introduced to improve the service performance of the equipment. However, most of the traditional antiwear and antifriction additives contain S, P, Cl and other elements, and friction reaction films with high melting point and low friction coefficient are generated by the active elements and friction side reactions to achieve the antifriction and antifriction effects, and the additives not only pollute the environment in the preparation and use processes, but also can cause the poisoning of three-way catalysts used for reducing the emission of automobile exhaust.
In recent years, with the increasing awareness of environmental protection, the requirements for environment-friendly lubricating oil and its additives are more and more urgent, and thanks to the rapid development of nano science and technology, the development of novel lubricating oil additives has been advanced sufficiently, and nano lubricating materials have shown superior and unique properties as a brand-new lubricating material system. The borate lubricating oil additive has the characteristics of good extreme pressure, wear resistance and antifriction performance (particularly better extreme pressure wear resistance under low kinematic viscosity), excellent thermal oxidation stability, corrosion resistance and sealing adaptability, no toxicity, no smell, certain biodegradability and the like, is widely used for gear lubrication, and shows huge energy-saving, consumption-reducing and environment-protecting potentials.
Although the anti-wear performance of the borate lubricating oil is greatly improved compared with that of the traditional anti-wear and anti-friction additive, the borate lubricating oil is difficult to be applied in high-strength friction environments, so that the borate lubricating oil is more beneficial to wide application of the borate lubricating oil by further enhancing the anti-wear performance of the borate lubricating oil.

Detailed Description
It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
As described in the background art, although the anti-wear performance of borate lubricating oil is greatly improved compared with that of the traditional anti-wear and anti-friction additives, the anti-wear performance of borate lubricating oil is difficult to meet the requirement of application in high-strength friction environments, so that the further enhancement of the anti-wear performance of borate lubricating oil is more beneficial to the wide application of borate lubricating oil.
In order to solve the above problems, the first aspect of the present invention provides a boronized rare earth lubricating oil additive, which includes a boronized rare earth extreme pressure antiwear agent, wherein the boronized rare earth extreme pressure antiwear agent specifically includes, by weight: 10-40 parts of borate, 5-10 parts of rare earth materials, 2-8 parts of silane coupling agents, 30-50 parts of dispersing agents and 10-30 parts of base oil.
Wherein, borate generates solid reactant film on the friction surface, and after borate and silane coupling agent are compounded, silane coupling agent molecules and borate coact to form an adsorption protection film on the metal surface. The specific reason is as follows: the silane coupling agent molecule consists of polar group and nonpolar group, the nonpolar group is hydrocarbon group and has lipophilicity, and the polar group (-COOH, -SO)3H, etc.) has hydrophilicity and also has affinity for metal surfaces. When the silane coupling agent is adsorbed on the metal surface, the longer nonpolar groups are closely arranged under the action of van der Waals force, so that the silane coupling agent and the borate act together to form a composite firm adsorption film. Meanwhile, the doping of the silane coupling agent in the adsorption film changes the charge state and the interface property of the metal surface, so that the energy state of the metal surface tends to be stable.
After the rare earth material is introduced into the system, the rare earth material can be grafted on silane coupling agent molecules, and the molecules are larger, so that the van der Waals attraction force to the metal surface is stronger, and the silane coupling agent can be quickly adsorbed to the metal surface by the attraction force. Therefore, the addition of the rare earth material can form a synergistic effect with the silane coupling agent, and the anti-wear and anti-wear effects of the lubricating oil are further improved.
Further, the boronized rare earth extreme pressure antiwear agent specifically comprises the following components in parts by weight: 10-30 parts of borate, 5-7 parts of rare earth materials, 2-5 parts of silane coupling agents, 30-40 parts of dispersing agents and 10-20 parts of base oil.
In one or more embodiments of the present invention, the borate salt includes one or both of sodium borate and potassium borate.

In one or more embodiments of the present invention, the rare earth material is any one or more of neodymium hydroxide, lanthanum hydroxide, and cerium hydroxide.
