Problems solved by technology

However, reducing the use of ZDDP will reduce the pressure resistance, friction resistance and oxidation resistance of the oil
With the new CF-4 specification issued by ILSAC (further improving the abrasion resistance and oxidation resistance under the premise of reducing the content of sulfur and phosphorus) will be fully enforced, this contradiction will become more prominent

Abstract

The invention discloses a multifunctional lubricating oil compound additive, which comprises a first antioxidant antiwear agent, a second antioxidant antiwear agent, a first antioxidant agent and a second antioxidant. The first antioxidant antiwear agent is selected from non-parathion-methyl type organic multimetallic compound and/or non-parathion-methyl type organic monometal compound, the second antioxidant antiwear agent is selected from organic boric acid ester compound and/or inorganic oil soluble boric acid salt compound, the first antioxidant agent is selected from dialkyl group diphenylamine and/or biphenols compound, and the second antioxidant is beta-(3,5-dule-tertiary butyl-4-hydroxycyclohexyl phenyl ketone) propionic acid isooctanol ester. The multifunctional lubricating oil compound additive contains no parathion-methyl, avoids ternary catalysis poisoning of automobiles, is environmentally friendly, has good antioxidant and anti-friction performance, can effectively restrain increase of oil product viscosity, prolongs service life of oil products, particularly can effectively restrain acidity change of the oil products, and prolongs long-time stability and service life of the oil products.

Description

technical field [0001] The invention relates to an additive, in particular to a multifunctional lubricating oil composite additive, which belongs to the field of chemical industry. Background technique [0002] In the automobile industry or engine industry, lubricating oil anti-friction additives are widely used additives to reduce oil friction, reduce equipment maintenance costs, and prolong engine life. The traditionally practical additive of this type is zinc dialkyl dithiophosphate (ZDDP), which has various functions such as anti-oxidation, anti-corrosion, extreme pressure and anti-wear. Since the middle of the 19th century, it has been widely used in internal combustion engine oil, Gear oil, hydraulic oil, etc. In recent years, with the increasingly stringent environmental protection regulations, in order to reduce the emission of harmful gases such as nitrogen oxides (NOx) in automobile exhaust, the field has begun to use three-way catalytic converters on gasoline eng...
