Problems solved by technology

Most of the engine oil grades of international brands are above SJ. At present, due to the continuous development of the automobile industry, engine lubricating oil has occupied a large market share of lubricating oil. The price of high-quality engine oil in the existing market is relatively high, while the price of low-priced engine oil is relatively high. The lubricating function of lubricating oil is relatively simple, and the effect is not ideal in the actual use process. The oil change interval of steam engine oil can not meet the basic requirements of the engine, which reduces the comprehensive performance of the product. Therefore, the inventor designed an anti-wear based on extreme pressure The gasoline engine oil of agent and preparation method thereof, solve above-mentioned technical problem

Abstract

The invention discloses gasoline engine oil based on an anti-wear reagent at extreme pressure and a preparation method of the gasoline engine oil, and the gasoline engine oil based on the anti-wear reagent at extreme pressure comprises the following components in parts by weight: 70-98 parts of base oil, 0.2-8 parts of the anti-wear reagent at extreme pressure, 0.1-5 parts of a tackifier, 0.05-5 parts of a metal deactivator, 0.05-5 parts of a pour point depressant, 0.5-2 parts of an antioxidant and 0.01-0.05 part of a demulsifier, the anti-wear reagent at extreme pressure is selected from one or more of tricresyl phosphate, sulfurized olefin, phenyl sulfide, sulfurized fatty acid ester, alkyl thiophosphate and a sulfur-nitrogen type anti-wear reagent at extreme pressure. According to the technical scheme, the extreme pressure anti-wear agent, the tackifier, the metal deactivator, the pour point depressant, the antioxidant and the demulsifier are mixed and matched with one another, the manufacturing process is simple, excessive processing equipment does not need to be input, the comprehensive performance requirement of the lubricating oil can be effectively and comprehensively improved, the maintenance and use period of gasoline engine oil is effectively prolonged, and the production cost is reduced. The anti-wear and anti-extreme pressure effects of the product are improved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of engine oil composition, in particular to an engine oil based on an extreme pressure antiwear agent and a preparation method thereof. Background technique [0002] Gasoline engine oil is called gasoline engine oil. In the API engine classification, it starts with the letter S. From SA to SM, each letter increases, the performance of the engine oil will be better than the previous one, and there will be more in the engine oil to protect the engine. additive. The further back the letter, the higher the quality level. Most of the engine oil grades of international brands are above SJ. At present, due to the continuous development of the automobile industry, engine lubricating oil has occupied a large market share of lubricating oil. The price of high-quality engine oil in the existing market is relatively high, while the price of low-priced engine oil is relatively high. The lubricating function of lubricat...
