Embodiment 1

[0020] 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 V112, tackifier V261 , pour point depressant P156 and antifoaming agent T901; the mass percentage of each component in the raw material is: composite agent OLOA59766 is 10%, anti-wear and antioxidant DAN8000 is 3%, tackifier V112 is 3%, tackifier V261 is 8%, pour point depressant P156 is 0.5%, antifoaming agent T901 is 0.001%, and the rest is base oil.

[0021] 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.

[0022] The main components of anti-wear and antioxidant DAN8000 are di-tert-butylphenol, methyl acrylate and a...

Embodiment 2

[0035] The present invention can adjust the mass percentage among the components according to actual needs, see Table 1.

[0036]

[0037] The rest of the ingredients are base oils.

[0038] The production process of this embodiment is the same as that of Embodiment 1.

Abstract

The invention relates to a formula and a production process of engine oil. The engine oil comprises base oil and additives, wherein the base oil comprises mineral base oil and synthetic base oil; the additives comprise complexing agent OLOA59766, anti-wear and anti-oxidation agent DAN8000, viscosity increaser V112, viscosity increaser V261, pour point reducer P156 and anti-foaming agent T901; and the base oil and the additives are mixed in a certain ratio. The engine oil is a product with ultra-long oil change period and low oil consumption, has good abrasion performance and high bearing capacity, has repair function on the abraded surface, has no pollution to the environment, improves energy conservation and prolongs the service life.

Description

technical field [0001] The invention relates to a formula of engine oil 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-specialized production ent...
