Abstract
The invention relates to the technical field of lubricating oil additives, in particular to a semi-solid high-strength membrane vehicle lubricating oil additive, a synthetic method thereof and lubricating oil. The molybdenum oxide is used as a base to react with o-aminobenzenesulfonic acid and alkylated diphenylamine, potassium permanganate is added, a method for adjusting the pH value is adopted to obtain an organic molybdenum amine mixture which is favorable for the next good reaction, and then the organic molybdenum amine mixture reacts with calcium titanate, methyl methacrylate and didodecyl methyl tertiary amine, and a two-step pressure method is adopted, so that the molybdenum-titanium alloy lubricating oil additive with good lubricity and excellent wear resistance is prepared, is dissolved in various lubricating oils in a liquid ion form, is a friction modifier, an anti-wear agent and an antioxidant of lubricating oil for internal combustion engines, has an obvious oil saving effect, and can obviously improve the film forming and bearing capacity of the lubricating oil. Forming a chemical adsorption film with the functions of friction reduction and wear resistance on the friction surface; under the harsh working conditions of high speed, high temperature, high pressure and the like, the engine is further protected.
Description
Technical Field
The invention relates to the technical field of lubricating oil additives, in particular to a semi-solid high-strength membrane vehicle lubricating oil additive, a synthetic method thereof and lubricating oil.
Background
The friction pair surface of modern engine is added with a layer of pre-lubricating material, the vehicle uses for a long time, the pre-lubricating material is consumed, and the general requirement of modern engine is to send out larger power on the premise of small volume and light weight, and the increasingly strict energy-saving and environmental protection requirements bring about the great increase of the engine power, and the piston connecting rod is shortened, and the load at the parts of piston ring and cylinder wall, valve tappet and cam, crankshaft and bearing bush, etc. which are the most strict in the working condition of the engine is greatly increased. In the case of an electronic fuel injection engine, especially a supercharged engine, high-temperature parts of the engine, such as pistons and cylinder walls, superchargers and the like, are considered to be more and more serious due to the problem of abrasion caused by a thin oil film. The conventional lubricating oil has the urgent requirements on corrosion resistance and abrasion resistance while the quality level is continuously improved so as to meet the requirements of overall lubrication and oil sludge dispersion of an engine.
The solid lubricant additive can avoid the friction effect generated by the forced fracture of substances between sliding surfaces, and the typical types of the solid lubricant additive are three types:
(one) inorganic layered structure substance: graphite, molybdenum disulfide, boron nitride, titanium metal, and the like. Compared with common lubricating oil, the titanium metal lubricating oil has three outstanding characteristics: (1) the titanium metal has strong corrosion resistance, and a layer of blunt oxide protective film can be generated when the engine is exposed to high-temperature air, so that when the engine is in a high-pressure and high-speed running state, the titanium lubricating oil can automatically track pressure points to generate a protective film, thereby reducing the abrasion of the engine and better protecting the engine; (2) the self-repairing titanium is used as liquid metal to enter the engine, so that the oxidation resistance of the engine can be improved, and the self-repairing titanium has a self-repairing function. The titanium-added engine oil forms a protective film at the most frequent friction place of the engine, which is like adding a wear-resistant shield to the wear point of the engine, and the engine can run for a longer time because the engine is protected at the molecular level; (3) the titanium lubricating oil for improving the heat dissipation of the automobile has very strong heat dissipation effect;
molybdenum disulfide is added after the renewal of four-generation products:
first generation molybdenum: molybdenum disulfide du (MoS2) is directly applied to bai, molybdenum disulfide is solid powder prepared by changing a molecular structure of molybdenum concentrate powder after chemical purification, the product is slightly silvery-gray in color black, has metallic luster and greasy feeling when being touched, is a good solid lubricant, is solid and cannot be dissolved in oil, and is only adopted in some lubricating grease at present.
Second generation molybdenum: sulfur-phosphorus-oxygen (S-P-O) organomolybdenum, starting to produce molybdenum dialkyl dithiosulfate (MODDP). The oil solubility of the product is improved, but the problem is not solved, sediment or gas generated by product decomposition can be generated when the process is unstable, and the phosphorus content is high, so that the poisoning of a tail gas catalyst is influenced, and the product is rarely applied at home and abroad at present.
Third-generation molybdenum: molybdenum alkyl dithiocarbamates (MoDTC), sulfur (S) -containing phosphorus (P) -free organomolybdenum, and in the eighth and ninety last century lubricating oil additive manufacturers developed to produce molybdenum dialkyl dithiocarbamates that, while phosphorus-free, are not oil soluble, friction reducing, and oxidation resistant, and that present a risk of corrosion and corrosion.
Fourth generation molybdenum: the product is the latest product which is pushed out in the century, is quite stable, solves the problem of oil solubility thoroughly, has low phosphorus content which is almost zero, has the greatest advantage of containing nitrogen and good high-temperature oxidation resistance, is widely used in high-grade SN lubricating oil with limit of S, P, and represents the development trend of organic molybdenum additives.
(II) Polymer Compound: the main representatives are polytetrafluoroethylene and nylon, polytetrafluoroethylene was originally used in grease and can now also be used in lubricating oil.
Cyanuric acid complex (MCA) is mainly used for light-duty grease and solder paste.
The solid lubricant additive has excellent performances of forming a film layer, reducing friction and the like through a direct action of a physical action mechanism at low temperature and high temperature, but when the solid lubricant is used in engine oil and gear oil, the solid lubricant needs to be stably dispersed in the oil, the particle size of solid particles is required to be in a range of 0.1-100 nanometers, and the solid lubricant cannot be coagulated, precipitated and block a filter and an oil pipe of a lubricating oil system under the condition of high and low temperature change to cause oil supply failure. At present, enough lubricating film layers can still be maintained at high temperature, lubricating oil flow failure cannot be caused at low temperature, or friction force is increased due to film layer thickness or film layer cracking, and the like, wherein the antiwear agents are mainly organic antiwear additives containing sulfur, phosphorus and nitrogen or containing boron, molybdenum, tungsten or rare earth elements, and additives synthesized based on graphene technology, nanotechnology and boron, molybdenum and tungsten technology. However, due to the pollution of the existing phosphorus-containing additive to the catalyst of the exhaust gas treatment device, more and more lubricating oil additives are concerned in the recent years that the phosphorus-free additive and the oil-soluble semi-solid high-strength film additive, such as the oil-soluble organic molybdenum additive, have excellent friction reduction and wear resistance. In view of this, research and development of a new lubricating oil additive have been carried out, which solves the defects of the existing additives, improves the protective effect of lubricating oil on engines, and becomes a problem to be solved urgently in the research and development process of lubricating oil additives.
