Description
Technical Field
The invention relates to wear-resistant engine oil, and belongs to the technical field of automobile parts.
Background
The engine oil has the functions of lubrication, wear reduction, auxiliary cooling, sealing, leakage prevention, rust prevention, corrosion prevention, shock absorption, buffering and the like for the vehicle engine. The rapid relative sliding exists between a piston and a cylinder of an engine, a main shaft and a bearing bush, and in order to prevent parts from being worn too quickly, an oil film needs to be established between two sliding surfaces, and the oil film with enough thickness separates the surfaces of the parts which slide relatively, so that the aim of reducing the wear is fulfilled. Meanwhile, the engine oil also has the function of auxiliary cooling, because the specific heat value of the engine oil is lower and is arranged inside the engine, although the engine oil does not have the cooling function, the heat energy is generated in the engine due to fuel combustion, and when the engine works, the engine oil can bring the heat back to the engine oil tank and then is dissipated to the air, so that the water tank is helped to cool the engine.
At present, the engine oil is replaced when the vehicle generally runs for five thousand kilometers, and the engine oil is replaced when the vehicle generally runs for ten thousand kilometers. The reason for oil change is that under the repeated cross driving conditions of high temperature, high speed and low temperature and low speed, the engine oil is easy to generate black oil sludge in the engine cylinder body, the gathered black oil sludge is easy to agglomerate in the cylinder and becomes a hard node which damages the cylinder surface and a piston ring, and if the black oil sludge is not removed in time, the effective power of the engine is reduced, and the emission of tail gas particles is increased. In recent years, development of nano metal self-repairing particles, graphene, nano ceramics and the like provides an effective method for effective maintenance in the operation process of an engine.
At present, nano metal self-repairing particles, graphene, nano ceramic, metal organic antiwear agents and the like are common means for increasing the abrasion resistance and the aging resistance of engine oil, but the problems of unstable performance, easy agglomeration, high cost, short service life of the engine oil and the like exist to different degrees.

Isooctyl adipate is also a lubricant and plays a role in auxiliary lubrication. The pentaerythritol ester and the isooctyl adipate are compounded into a new synthetic oil system, so that the synthetic oil system has the characteristics of excellent abrasion resistance, ageing resistance, good high-low temperature stability and the like, and the abrasion resistance and the oil change period of the engine oil are greatly improved.

The phenol antioxidants are generally used in internal combustion engine oil, hydraulic oil and transformer oil at a relatively low temperature range; the amine antioxidant has higher use temperature than that of phenol antioxidant, especially the alkylated diphenylamine antioxidant has high temperature oxidation resistance, and may be used in synthetic ester oil as the main antioxidant component of jet turbine engine lubricating oil. The oxidation test results show that the compounds can reduce the increase of the viscosity of oil products and reduce the weight loss of bearings. When the antioxidant is used in polyol ester, the antioxidant effect is obvious, the metal corrosion is small, the viscosity increase is small, and the formed oil sludge is little.
The amine and epoxy compound condensate is a demulsifier which can rapidly separate oil from water on the premise that the engine oil has a trace amount of water, thereby preventing the oil from emulsifying.
The dimethyl silicone oil is a defoaming agent, can be used for quickly defoaming, and can reduce the reduction of temperature reduction and wear resistance effects caused by the generation of foams in the operation process of oil products.
The organic molybdenum, the nano boron antiwear agent and the nano biological bone charcoal powder are used as the antiwear agent, play a role in lubricating, reduce the friction resistance and reduce the abrasion. Wherein, the nano boron antiwear agent is usually 100-500 nm. The nano biological bone charcoal powder is usually 10-200nm, preferably 50 nm. The nanometer biological bone charcoal powder is selected from at least one of nanometer cattle bone charcoal powder, nanometer pig bone charcoal powder, nanometer horse bone charcoal powder, nanometer fish bone charcoal powder, and nanometer sheep bone charcoal powder.

According to the invention, the nano biological bone charcoal powder is added into the engine oil formula for the first time, so that the lubricating oil has a rolling lubricating effect, better abrasion resistance and adaptability, a good abrasion resistance effect is achieved, and the problems of engine oil agglomeration and short oil change period are solved. The nanometer biological bone charcoal powder is amorphous carbon, and mainly comprises carbon and calcium phosphate which are antiwear agents with excellent performance, so that the nanometer biological bone charcoal powder is dispersed in engine oil, has a very good rolling lubricating effect, and can absorb shock and buffer. When the pressure of the cylinder opening of the engine rises sharply, the load on the piston, piston scraps, a connecting rod and a crankshaft bearing is increased suddenly, and the load is transmitted and lubricated by the bearing, so that the borne impact load plays a role in buffering. The friction surface is added with the nano biological bone charcoal powder, so that the friction coefficient can be reduced, thereby reducing the friction resistance, saving the energy consumption and reducing the abrasion, and the abrasion caused by abrasive wear, surface fatigue, adhesive wear and the like can be reduced between the friction surfaces.
Through further research, the pentaerythritol ester base oil and the nano biological bone charcoal powder are added simultaneously, the pentaerythritol ester base oil and the nano biological bone charcoal powder have obvious synergistic effect, the maximum seizure-free load and the sintering load of the engine oil can be obviously improved, and the anti-aging time is prolonged. The reason may be that pentaerythritol ester is a star-shaped ester structure and can form a layer of compact lubricating oil film on the metal surface; the nanometer bone charcoal powder forms a rolling steel ball structure between the friction pairs, so that friction is reduced, the lubricating effect is improved, and abrasion is reduced; when the pentaerythritol ester and the nanometer bone charcoal powder are added simultaneously, the pentaerythritol ester is in a star-shaped structure and is coated on the surface of the nanometer bone charcoal powder to form a core-shell structure, and the lubricating and extreme pressure effects are exerted simultaneously, so that an obvious synergistic effect is generated, and the abrasion resistance and the oil change period of the engine oil are greatly improved. Through experimental tests, the ordinary engine oil is changed for 5000 kilometers generally, while the engine oil of the invention can run for more than 20000 kilometers and the mileage is four times of the ordinary engine oil.
The engine oil of the present invention is prepared according to the above formulation by a conventional method in the art. The engine oil of the invention has excellent wear resistance and an ultra-long oil change period, is suitable for various vehicles, and is particularly suitable for professional racing cars, special vehicles and the like.
