AI Technical Summary
Existing lubricating oils cannot effectively prevent wear between cylinders and piston rings under high temperature and high pressure environments, especially the waist-shaped wear near the top dead center, resulting in poor lubrication.
It uses a smart, concentrated self-healing lubricant containing magnesium hydroxysilicate, hydroxymethylpropyl cellulose, and a suspending agent. Through forced lubrication, the repair material reaches the friction surface, forming an iron-based silicate protective layer to prevent wear.
It enables the lubricating oil to automatically repair itself, extend its service life, improve its oxidation resistance, viscosity-temperature properties, low-temperature fluidity and shear stability, reduce wear, and generate a wear-resistant protective layer.
Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive lubricants, specifically to a smart, concentrated, self-healing lubricant. Background Technology
[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering (Roab).
[0003] Any substance that can reduce friction and wear between two objects in relative motion is called lubricant.
[0004] Piston rings impede the movement of lubricating oil. Some of the lubricating oil that enters the upper part of the cylinder will be subjected to high temperature and pressure during the compression and power strokes, eventually burning. The piston impacts the load, which often affects the lubrication between the cylinder and piston rings, resulting in heat dissipation. Ultimately, the cylinder radial direction will experience varying degrees of wear, especially near top dead center, leading to circumferential wear. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide an intelligent concentrated self-healing lubricating oil that addresses the above-mentioned issues.
[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: an intelligent concentrated self-healing lubricating oil, characterized in that it comprises the following components in weight percentage:
[0007] 0.04% magnesium hydroxysilicate, 1% hydroxymethylpropyl cellulose, 0.3% suspending agent, and the balance being base oil.
[0008] As an improvement, the suspending agent is a molecular suspension synergist.
[0009] As an improvement, its usage method is as follows:
[0010] ① Inject the repair material into the cylinder, avoiding reaching the top of the living site;
[0011] ② Cut off the oil supply system and start the motor three times continuously, with a 10-second interval between starts and a 5-second start time each time. Forced lubrication allows the repair material to reach the friction surface, and the repair is performed through piston action.
[0012] The advantages of this invention compared to existing technologies are as follows: the intelligent concentrated self-repairing lubricating oil of this invention prevents wear, has an automatic repair function, and is more energy-saving and environmentally friendly. It further extends the service life of conventional lubricating oil, has higher oxidation resistance, better viscosity-temperature characteristics, better low-temperature fluidity, and better shear stability, anti-wear properties, and repair function. It improves the overall performance of lubricating oil, enhances the quality of existing finished lubricating oils, and has great practicality, feasibility, and significant economic value. Detailed Implementation
[0013] The present invention will now be described in further detail.
[0014] In a specific implementation, this invention provides an intelligent concentrated self-healing lubricating oil, characterized by comprising the following components in weight percentage:
[0015] 0.04% magnesium hydroxysilicate, 1% hydroxymethylpropyl cellulose, 0.3% suspending agent, and the balance being base oil.
[0016] As an improvement, the suspending agent is a molecular suspension synergist.
[0017] As an improvement, its usage method is as follows:
[0018] ① Inject the repair material into the cylinder, avoiding reaching the top of the living site;
[0019] ② Disconnect the oil supply system and start the engine three times, with a 10-second interval between starts and a 5-second start time each time. This forced lubrication allows the repair material to reach the friction surfaces, and the piston action performs the repair. The repair material can also be effectively added to the engine oil, ultimately restoring engine performance.
[0020] The working principle of this invention is as follows: After adding this product to the lubricating oil, as the lubricating oil circulates, a ceramic-like protective layer with extremely high surface hardness and smoothness, extremely low coefficient of friction, excellent self-lubricating performance, strong corrosion resistance and high temperature resistance, and excellent anti-wear and friction reduction performance is automatically generated on the friction surface. The thickness can be adjusted from 5μm to 0.2mm, thus achieving the function of preventing wear and automatic repair of the concentrated lubricating oil.
[0021] Intelligent concentrated self-healing lubricating oil is a group of oils composed of magnesium hydroxysilicate [Mg6(Si4O3)2] 10[(OH)8] Magnesium silicate is a micron-sized particulate material composed of natural mineral materials. It belongs to silicate minerals and is composed of magnesium, silicon, and hydrogen elements, with hydrogen mainly existing in the form of hydroxyl groups. Hydroxyl magnesium silicate typically exists in fibrous, flake, columnar, and powder forms, possessing high physicochemical properties and wide application value. Primarily derived from natural mineral materials, these inorganic materials are insoluble in grease, do not chemically react with grease, do not change the viscosity or other physicochemical properties of the oil, have no toxic side effects, and are chemically very stable at room temperature. When existing grease is used as a carrier to introduce these particulate materials into the friction pair, these particulate materials undergo ultra-fine grinding, resulting in a series of physical and chemical changes that alter the metal microstructure of the friction surface.
[0022] The physical changes that occur on the metal friction surface with this product are as follows: using the existing lubricating oil as a carrier, it enters the friction pair. Under the action of frictional energy, the ultrafine particles are further crushed. At this time, the tiny particles produce an ultra-fine grinding effect on the metal friction surface. The ultra-fine grinding effect of the particles with sufficient hardness causes the micro-protrusions on the metal surface to break, which further improves the smoothness of the bearing friction surface.
[0023] The chemical change that occurs on the metal friction surface in this product is as follows: During ultra-precision grinding, the flash heat generated when the micro-protrusions fracture causes a displacement reaction between magnesium atoms in the microcrystalline particles and iron atoms on the friction surface, forming an iron-based silicate protective layer, also known as a cermet layer, on the iron-based metal friction surface. This iron-based silicate protective layer is formed when the micro-protrusions on the metal surface fracture and flash heat occurs; no frictional heat is generated in non-wear areas, and no chemical displacement reaction occurs. Therefore, the formation of this iron-based silicate protective layer is selective; it only forms a wear-resistant protective layer on the metal friction surface. As wear continues on the moving friction pair surface, the fracture of the micro-protrusions and the released heat energy from the wear cause this chemical displacement reaction to continue. Once a cermet protective layer is formed on the surface, its surface smoothness improves, the coefficient of friction decreases, the heat energy generated by friction decreases, and the chemical displacement reaction stops. However, when this wear-resistant protective layer is damaged, the frictional heat on the metal surface increases sharply, and a new displacement reaction will begin, causing the wear-resistant protective layer to automatically return to its original nominal size.
