Problems solved by technology

At present, the CH-4 / CI-4 grade diesel engine oil on the market has an oil change mileage of about 30,000 kilometers, which belongs to the conventional oil change mileage. The performance of the above products needs to be further improved in terms of energy saving, economy and user experience. And because the application of high-nitrogen and high-sulfur additives in the compounding agent of existing diesel engine oil has caused serious pressure to environmental protection, therefore be badly in need of developing a kind of long oil change period environment-friendly diesel engine oil and its manufacturing method

Abstract

The invention relates to the field of petrochemical industry, and relates to an environmentally-friendly diesel engine oil with long oil drain intervals, and a preparation method thereof. The engine oil is prepared from 15-25% of a compounding agent, 2-10% of a viscosity index improver, 0.1-1% of a pour point depressant, 0.2-2% of an antioxidant, 0.5-5% of an anti-wear agent, and the balance of whole synthetic base oil. The compounding agent added to diesel engine oil improves the wear resistance of the engine oil and reduces the wearing of parts, and synergistic effects between molybdenum diisooctyldithiocarbamate and ashless phosphorodithioate improve the wear resistance of the diesel engine oil; the addition of polyalphaolefin (PAO) base oil to the diesel engine oil improves the low temperature performances of the diesel engine oil, the addition of alkyl naphthalene AN25 base oil improves the thermo-oxidative stability of the diesel engine oil and prolongs the service life of the diesel engine oil, and the addition of a borated polyisobutylene succinimide dispersant, a sulfurized calcium alkyl phenolate detersive and the low-nitrogen element additive reduces the emission of nitrogen oxides in order to make the diesel engine oil environmentally friendly.

Description

technical field [0001] The invention relates to the field of petrochemical industry, and relates to a long oil change cycle environment-friendly diesel engine oil and a manufacturing method thereof. Background technique [0002] Environmental protection, energy saving, and extended oil change intervals are the main driving forces to promote the development and progress of oil product specifications. With the continuous upgrading of emission regulations, it is no longer possible to meet the increasingly stringent emission regulations by relying only on internal purification measures. Engine manufacturers adopt various new technologies, such as oxidation catalyst (DOC), particulate filter (DPF), selective reduction catalyst (SCR), nitrogen oxide trap (LNT), exhaust gas recirculation (EGR) and other technologies, in order to make its engines meet increasingly stringent emission regulations. [0003] my country's emission standards are formulated using the Economic Commission f...
