Problems solved by technology

[0006] In order to solve the problem of high temperature and easy oxidation of sulfur and phosphorus antiwear agents, patent CN103756761A added nano-boron additives, and patent CN103351912A added T362 (calcium hexadecyl borate), but the oil solubility of boron substances is not good. Poor, long-term storage is easy to precipitate, affecting the use effect, and boron substances are easy to hydrolyze, if water is mixed into the oil during use, boron substances are easily hydrolyzed and lose the anti-wear effect

Abstract

The invention discloses energy-saving diesel engine oil with ultra-long oil change mileage and a preparation method thereof. The energy-saving diesel engine oil is prepared from, by mass, 10-18% of diesel engine oil complexing agent, 0.3-0.8% of anti-wear agent, 0.5-1.5% of antioxidant, 3-8% of viscosity index improver, 0.002-0.005% of anti-foaming agent and the balance synthesized basic oil. The energy-saving diesel engine oil has high wear resistance and friction reduction performance, high oxidation stability and high thermal stability, and the oil change cycle can be effectively prolonged; by means of the anti-wear agent without sulfur and phosphorus, the wear resistance and friction reduction performance are effectively improved, and the oxidation of an oil product can not be accelerated; alkyl multi-benzyl toluene is added to basic oil, and through the good complexing effect of alkyl multi-benzyl toluene and antioxidant, the antioxidant performance of the oil product is improved, the use cycle of the oil product is greatly prolonged, and the ultra-long oil change aim is achieved.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, and relates to an energy-saving diesel engine oil with super long oil change mileage and a preparation method thereof. Background technique [0002] Since the development of my country's automobile industry in the 1950s, it has become a major country in automobile production and consumption. It is predicted that by 2020, the number of automobiles in my country will reach 130 million, and it is expected to become the world's largest automobile market. With the development of the automobile industry, the comprehensive performance of diesel engines has been further improved, and correspondingly, it is required to improve the performance of diesel engine oil. Energy saving and extended oil drain intervals are the driving force behind the replacement of internal combustion engine oil. This requires diesel engine oil to have good high-temperature detergency, oxidation resistance, and anti-wear...
