Problems solved by technology

[0003] Automobiles with engines using natural gas are more and more widely used. The temperature of the combustion chamber of this type of engine is high, and the temperature of the exhaust gas is high. The lubricating oil of the engine is easily oxidized, carbonized, and sludge is formed, which increases the carbon deposit inside the engine. , affecting the normal operation of the engine
In addition, in order to improve the lubricating performance and reduce the viscosity of lubricating oil, many lubricating oils can ensure the good work of the parts in actual work. However, under high temperature conditions, this kind of lubricating oil is volatile, resulting in Lubricants have a shorter lifespan

preparation example Construction

[0023] The preparation method of the above-mentioned hydrophobically modified nano-scale silicon oxide is: the nano-scale silicon oxide is soaked in the silane coupling agent KH-570.

[0024] The preparation method of above-mentioned engine lubricating oil is:

Embodiment 1

[0026] S1: Add rapeseed oil and four-line oil to the reaction kettle, heat to 60°C, and stir for 1 hour;

[0027] S2: add vulcanized cottonseed oil, 10# hydrogenated engine oil, oleic acid, alkenyl succinic acid, silicone oil, calcium petroleum sulfonate, zinc salt of thiophosphobutanol, benzotriazole, hydrophobically modified nano-scale oxidation Silicon, heated to 70°C, stirred for 0.5h, cooled to 50°C

[0028] S3: Add chlorinated paraffin, polyacrylate, alkylnaphthalene, dodecanol diethanolamine, isopropanol, polypropylene glycol, polyisobutylene succinimide, sorbitan monooleate, diphenylamine, in Stir at 50 °C for 1 h.

Embodiment 2

[0030] The difference from Example 1 is: in step S1, the temperature is 65°C; in step S2, the temperature is heated to 75°C and cooled to 55°C; in step S3, the temperature is 55°C.

Abstract

The invention provides a highly wear-resistant engine lubricating oil, and belongs to the technical field of lubricating oil. The lubricating oil comprises the following components, by weight: 20-30 parts of rapeseed oil, 30-50 parts of HVGO, 10-20 parts of vulcanized oil cottonseed oil, 20-40 parts of 10# hydrogenation oil, 2-10 parts of oleic acid, 2-5 parts of alkenyl succinic acid, 1-10 parts of silicone oil, 1-2 parts of a metal detergent, 2-3 parts of parathion butyl octanol zinc salt, 5-10 parts of chloroparaffin, 3-6 parts of polyacrylate, 2-4 parts of alkyl naphthalene, 3-5 parts of dodecyl alcohol diethanol amine, 3-5 parts of isopropyl alcohol, 2-4 parts of poly propylene glycol, 1-3 parts of polyisobutylene succinimide, 1-2 parts of disecondary alcohol zinc dialkyl dithiophosphate, 2-3 parts of of benzo triazole, 1 part of hydrophobically modified nano silicon oxide, 2-4 parts of diphenylamine, 3-6 parts of sorbitan monooleate, and 2-9 parts of diphenylamine. Compared with a conventional lubrication oil, the engine lubricating oil provided by the invention has particularly prominent wear resistance.

Description

technical field [0001] The invention provides a lubricating oil, in particular to a highly anti-wear engine lubricating oil, which belongs to the technical field of lubricating oil. Background technique [0002] During the working process of the engine, a large number of parts are adjusted and operated. These moving parts form many friction pairs, and proper lubrication is required between the friction pairs to reduce friction loss. Engine lubricating oil has the functions of lubrication, cooling, cleaning, shock absorption, sealing and antirust, and requires proper viscosity, high temperature resistance, oxidation resistance and good thermal stability. In addition, it should also have good lubricity, certain extreme pressure and clean dispersion. It is required to have good corrosion resistance, anti-foaming properties, and the ability to neutralize acidic substances. [0003] Automobiles with engines using natural gas are more and more widely used. The temperature of th...
