Embodiment 1

[0021] The raw materials of this embodiment include base oil and additives, and the base oil includes mineral base oil and synthetic base oil; the additive includes complex agent OLOA59766, anti-wear antioxidant DAN8000, tackifier V251, tackifier V6730 , pour point depressant P156 and antifoaming agent T901; the mass percentage of each component in the raw materials is: composite agent OLOA59766 is 8%, anti-wear and antioxidant DAN8000 is 3%, tackifier V251 is 7.5%, tackifier V6730 is 3%, pour point depressant P156 is 0.5%, antifoaming agent T901 is 0.002%, and the rest is base oil.

[0022] In this example, the main components of the composite agent OLOA59766 are calcium, molybdenum, boron, nitrogen, and zinc, which function as excellent lubricity and extreme pressure resistance, greatly reduce friction coefficient and wear, and achieve excellent energy-saving effects.

[0023] The main components of anti-wear and antioxidant DAN8000 are di-tert-butylphenol, methyl acrylate a...

Embodiment 2

[0036] The present invention can adjust the mass percentages among the components according to actual needs, see Table 1.

[0037]

[0038] The rest of the ingredients are base oils.

[0039] The production process of this embodiment is the same as that of Embodiment 1.

Abstract

The invention relates to a formulation of lubricating oil specially used for a taxi and a production technology thereof. The raw materials of the lubricating oil specially used for the taxi comprise base oil and an additive, wherein the base oil comprises mineral base oil and synthetic base oil; the additive comprises complex agent OLOA59766, wear-resistant antioxidant DAN8000, thickening agent V251, thickening agent V6730, pour point depressant P156 and anti-foaming agent T901; and the base oil and the additive are mixed together according to a certain proportion. The lubricating oil is specially used for the taxi, and an oil film is ultra-stable, so that more comprehensive protection is provided for an engine, and the service life of the engine can be prolonged.

Description

technical field [0001] The invention relates to a formula of special lubricating oil for taxis and a production process thereof. Background technique [0002] China is the third largest consumer of lubricating oil in the world, with an annual consumption of nearly 4 million tons and an increasing trend year by year. In China's lubricating oil market, after years of competition, the competition pattern has gradually formed. Most of my country's high-end automotive lubricating oil market is occupied by foreign well-known brands, domestic companies mainly occupy the mid-range oil product market, and most local and private enterprises rely on mid-range oil products. , The low-grade oil market can survive. Judging from the actual situation of domestic lubricating oil production enterprises, although we already have lubricating oil enterprises with international advanced level, such as the Great Wall Lubricating Oil Company affiliated to Sinopec, there are still some small non-spe...
