Description
Technical field：
The present invention relates to gasoline engine oil technical fields, and in particular to a kind of gasoline engine oil SM10W-40 and preparation method thereof.
Background technology：
Gasoline engine oil SM10W-40 refers to the SM formed with the addition multiple functions additive modulation of high viscosity index (HVI) base oil
The technical conditions of gasoline engine oil.The SM grades of machine oil for highest quality of gasoline grade, 10W-40 refer to the viscosity grade of machine oil, W
What is represented is low temperature viscosity grade, and the numerical value before W is smaller, and low temperature viscosity is smaller, and low temperature flow is better, illustrate machine oil for
The environment temperature used is lower；40 representatives are high-temperature viscosity grades, and number is bigger, and its viscosity is bigger, and the environment temperature used is got over
It is high.
Gasoline engine oil SM10W-40 has been widely used in the equipment such as light duty vehicle engine, as China becomes a full member of WTO,
Requirement of the country to environmental protection is higher and higher, and the automobile of advanced level will be more introduced into, and the demand of high-grade I. C. engine oil more can
Increasing, the competition of domestic top grade machine oil also can be more and more stronger.To further reduce the gap with world level, strive in state
Inside occupy more high-grade I. C. engine oil market shares, therefore the development for carrying out high-quality I. C. engine oil is the task of top priority.For this purpose, I
Company has successfully developed SM10W-40 gasoline engine oils.
Invention content：
The technical problems to be solved by the invention are that providing a kind of simple and practicable preparation manipulation, cryogenic property and high temperature resists
Good gasoline engine oil SM10W-40 of polishing machine and preparation method thereof.
The technical problems to be solved by the invention are realized using following technical solution：
A kind of gasoline engine oil SM10W-40, is made of the raw material of following mass percent：
High viscosity index (HVI) base oil 81%
Viscosity index improver 11.1%
Compound additive HiTEC9890 7.9%.
Preparation method includes the following steps：
(1) high viscosity index (HVI) base oil is squeezed by oil pump in blending kettle, and is warming up to 55~65 DEG C of insulated and stirreds；
(2) viscosity index improver and compound additive HiTEC9890 are added in into blending kettle successively, continues at 55~65
DEG C insulated and stirred is uniformly mixed；
(3) above-mentioned uniformly mixed oil product is placed in sealing and standing 24-48h in 0-5 DEG C of environment, then is warming up to 55~65 DEG C
More than insulated and stirred 5min；
(4) sampling is chemically examined, and chemically examines warehousing after passing, you can gasoline engine oil SM10W-40.
The viscosity index (VI) of the high viscosity index (HVI) base oil is 90-120.
The viscosity index improver selects OCP type viscosity index improvers, i.e. ethylene-propylene copolymer.
The viscosity index improver is modified by ethylene-propylene copolymer, and method of modifying is：Ethylene-propylene copolymer is heated
To 120-130 DEG C of insulated and stirred, hexamethylolmelamine pregnancy ether and ferrocene are added, continues at 120-130 DEG C and protects
Temperature stirring 0.5-1h, then adds in butyl titanate, and the insulated and stirred 0.5-1h again at 120-130 DEG C, gained mixture
Cooled to room temperature is to get viscosity index improver.
The ethylene-propylene copolymer, hexamethylolmelamine pregnancy ether, ferrocene, butyl titanate mass ratio be 35-
50:5-10:0.05-0.5:1-5。
By the above-mentioned modification to ethylene-propylene copolymer, retaining the original tackifying ability of ethylene-propylene copolymer and shear stability
Improve its cryogenic property simultaneously, reduce the viscosity change amplitude brought by low temperature environment；And enhance the height of made gasoline engine oil
Warm wear resistance.
The beneficial effects of the invention are as follows：The present invention is improved using high viscosity index (HVI) base oil as major ingredient by viscosity index (VI)
Agent and compound additive HiTEC9890's is used cooperatively, and the property indices of made gasoline engine oil SM10W-40 is made to meet
National standard meets the requirement of light vehicle；Also, the low temperature performance excellent of made gasoline engine oil SM10W-40 reduces
The viscosity change amplitude brought by low temperature environment；There is preferable abrasion-resistance and relatively low friction coefficient simultaneously, ensure gasoline
The use quality of machine oil, and extend the service life of gasoline engine oil.Wherein, by 0-5 DEG C of low-temperature treatment, improve gasoline engine oil
Temperature performance, viscosity is too small so as to influence the normal use of gasoline engine oil when preventing during low temperature excessive viscosity, high temperature.
