Abstract
The present invention relates to a lubricating oil composition which is made from a thiophoshonated polyisobutyene barium salt, a sulfurized alkyl phenate, a polyisobutyene butanediimide ashless dispersant, an antioxidant, a pour depressor, an antifoaming agent and base oil of mineral oil. The lubricating oil composition prepared by 6.0% of addition quantity has the advantages of favorable lubricating property, favorable high temperature purification property and favorable antioxygen corrosion resistance, and is suitable for the lubricating requirements of SD gasoline engine oil, CC diesel engine oil and SD/CC universal engine oils. The lubricating oil composition meets the specification index requirements of GB11121 and GB11122.
Description
The present invention relates to a kind of lubricating oil composition, especially a kind of SD level gasoline engine oil that is applicable to, CC level diesel engine oil, SD/CC level general purpose engine oil compositions belongs to mineral oil origin lubricating composition class technical field.It has good cleansing performance, greasy filth dispersing property, resistance to wears anti-oxidant and corrosion resistance.
As everyone knows, China's automobile and engine building to lubricating oil need with abroad compare, obviously different, to SD level gasoline engine oil, the requirement of CC level diesel engine oil is still occupied an leading position.
Chinese patent CN-1138624A, CN-1138621A are a kind of lubricating oil compositions.It is to add the lubricating oil product that a kind of at least ashless dispersant, a kind of purification agent and a kind of oxidation and corrosion inhibitor can prepare SC, SD, CC, CD, SC/CC, SD/CC specification with a large amount of mineral oil.
Chinese patent CN-1138622A and CN-1138623A, CN-1049679A provide the lubricating oil composition of a kind of GB11121SF of satisfying and APISF, APISG gasoline engine oil specification.
In the patent of being found, be not that host is as engine oil composition with the sulfur phosphorization polyisobutylene titanate salt.
The object of the present invention is to provide a kind of with the sulfur phosphorization polyisobutylene titanate salt be host as engine oil composition, and have better economic.Said sulfur phosphorization polyisobutylene titanate salt among the present invention, it is a kind of high base number product (barium content is greater than 15.0%, and base number is greater than 120mgKOH/g).Sulfur phosphorization polyisobutylene titanate salt contains a certain amount of alkyl monosulfide phenates component.Therefore, it is a kind of high base number, polycomponent, and multi-functional compound purification agent has peace and quiet preferably dispersive ability, and anti-oxidant corrosion resistance is the comprehensive purification agent of a kind of performance.The carbon deposit that it forms is soft than calcium salt, and abrasion resistance is also better.Particularly the production cost of sulfur phosphorization polyisobutylene titanate salt than other metal detergent such as salicylate, sulfonate is low, good economy performance.The present invention fully takes into account these performances and the characteristics of sulfur phosphorization polyisobutylene titanate salt itself, has designed to be applicable to CC, SD, SD/CC level oil lubrication oil compositions.
The invention provides a kind of have good piston detergency, oilness, anti-oxidant and wear-resistant engine oil composition.Lubricating oil composition of the present invention comprises following component:
Sulfur phosphorization polyisobutylene titanate salt (A)
Alkyl monosulfide phenates (B)
Polyisobutene succinimide ashless dispersant (C)
Oxidation inhibitor (D)
Pour point depressant (E)
Kilfoam (F)
Mineral oil basis oil (G)
Wherein component (A) accounts for the 1.0-6.0% of composition gross weight, component (B) accounts for the 0.2-1.5% of composition gross weight, component (C) accounts for the 0.3-3.0% of composition gross weight, component (D) accounts for the 0.2-2.0% of composition gross weight, component (E) accounts for the 0.1-1.0% of composition gross weight, component (F) accounts for the 0.001-0.1% of composition gross weight, and component (G) accounts for the 75.0-95.0% of composition gross weight.
Major technique feature of the present invention is to be that host is as one of engine oil composition with the sulfur phosphorization polyisobutylene titanate salt, utilize the compatibleness of purification agent, dispersion agent, oxidation inhibitor, make composition properties reach best, the dosage that adds with 6.0% makes composition quality reach the standard of GB 11121 L-ESD and GB11122 L-ECC, the Technological Economy of this invention at present level that is in a leading position at home.
In the composition of the present invention, the ratio of various base oils and additive by board-like coking device test, the heat pipe oxidation test determines, the actual condition of lubricating oil work has been simulated in these tests effectively.
In the preparation oil product, the effective level of each component is as follows:
M% m% forms general range preferable range sulfur phosphorization polyisobutylene titanate salt, (A) 1.0-6.0 1.5-5.0 alkyl monosulfide phenates, (B) 0.2-1.5 0.25-1.4 polyisobutene succinimide ashless dispersant, (C) 0.3-3.0 0.4-2.5 antioxidant, (D) 0.2-2.0 0.4-1.5 pour-point depressant, (E) 0.1-1.0 0.2-0.8 anti-foaming agent, (F) 0.001-0.1 0.001-0.002 mineral oil basis oil, (G) 75.0-95.0 80.0-95.0
(E) in the said components joined in (G) earlier and fully stirred 2 hours down at 80 ± 5 ℃, added component (F) restir then 2 hours, adding (A), (B), (C), (D) each component stirred 3 hours then, mix to composition, can obtain L-ECC, L-ESD, L-ESD/CC engine oil.Select (G) component of different viscosity, can modulate 30,40 other CC of different viscosity level, SD/CC, SD level oil product.
According to the documents and materials statistics, occupy an leading position with middle-grade SD, CC, SD/CC level oil product in the annual required I. C. engine oil of China, from the real current situation of China, the present invention will have vast market prospect and economic benefit.
The enforcement of following example is to further specify of the present invention, is not to limit the scope of the invention.Embodiment one
