Problems solved by technology

The oil solubility of this product has been improved, but there is still no fundamental solution. When the process is unstable, precipitation will occur or the product will decompose to generate gas, and due to the high phosphorus content, it will affect the poisoning of the exhaust catalyst, so it is rarely used abroad.
[0008] The third generation of molybdenum: Molybdenum dithiocarbamate (MoDTC), organic molybdenum containing sulfur (S) and no phosphorus (P). In the 1980s and 1990s, lubricating oil additive manufacturers developed and produced dialkyl dithiocarbamate Oxymolybdenum thiocarbamate, although this product does not contain phosphorus, it has poor oil solubility, anti-friction and anti-oxidation properties, and there is a risk of rust and corrosion
[0012] Solid lubricant additives have excellent properties such as forming a film layer, and can directly reduce friction through physical mechanisms at low or high temperatures. However, when solid lubricants are used in engine oils and gear oils, they need to be stably dispersed in the oil , the solid particle size is required to be within the range of 0.1 to 100 nanometers, and it must not be condensed and precipitated under high and low temperature changes, so as to block the filter and oil pipe of the lubricating oil system, causing oil supply failure

Abstract

The invention relates to the technical field of lubricating oil additives, in particular to a semisolid high-strength film vehicle lubricating oil additive, a synthesis method thereof and lubricating oil. Molybdenum oxide is used as a basis to react with o-aminobenzene sulfonic acid and alkylated diphenylamine, then potassium permanganate is added, a method of adjusting the pH value is adopted to obtain an organic molybdenum amine mixture beneficial to a good reaction in the next step, 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 the molybdenum-titanium alloy lubricating oil additive with good lubricity and excellent wear resistance is prepared, is dissolved in various lubricating oil in a liquid ionic form, is a friction modifier, an anti-wear agent and an antioxidant of the lubricating oil for an internal combustion engine, has a remarkable oil-saving effect, and can remarkably improve the film-forming capacity and the bearing capacity of the lubricating oil. A chemical adsorption film with antifriction and antiwear effects is formed on the friction surface; and the engine is further protected under harsh working conditions such as high speed, high temperature and high pressure.

Description

technical field [0001] The invention relates to the technical field of lubricating oil additives, in particular to an automotive lubricating oil additive with a semi-solid high-strength film, a synthesis method thereof, and a lubricating oil. Background technique [0002] A layer of pre-lubricating material is added to the surface of the friction pair of the modern engine. The long-term use of the vehicle consumes the pre-lubricating material, and the general requirement of the modern engine is to generate greater power under the premise of small size and light weight, and the requirements are becoming more and more stringent. The requirements of energy saving and environmental protection bring about a substantial increase in engine power, and the shortening of the piston and connecting rod greatly increases the load on the piston ring and cylinder wall, valve lifter and cam, crankshaft and bearing bush, etc., which are the most demanding engine working conditions. . For EF...
