Description

Two-stroke engine lubricating oil compositionss and its manufacture method
Technical field
The present invention relates to a kind of two-stroke engine lubricating oil compositionss.Specifically, this It is bright to be related to a kind of antioxygenic property, detergent-dispersant performance energy, antifriction performance and high rust resistance Two-stroke engine lubricating oil compositionss.
Background technology
For two stroke engine is compared with four-stroke engine, due to design it is simple, easily fabricated, It is easy to maintenance, specific volume power to be widely used in various equipment greatly, for example, rubs Motorcycle, outboard motor for ship, motor boat, autocycle, generating set, chain Saw and power mower etc..Two-stroke engine lubricating oil can be burnt with fuel in the course of the work Fall, combustion product easily generates sooting of the spark plug, and causes compression ring bonding, air vent blocking And the abrasion of piston ring and cylinder, so needing the energy for preferably suppressing deposit to generate Power and wear resistance.In recent years, two stroke engine is towards high rotating speed, high-power direction Development, severity increase, and two stroke engine first piston ring groove temperature may be up to 295～315 DEG C, this is just clear to the high temperature antioxygen property and high temperature of two-stroke engine lubricating oil Static stability can propose requirements at the higher level.
The two-stroke for seeking more efficiently antioxidant additive and exploitation novel high-performance is started The target that machine lubricating oil, always those skilled in the art are made great efforts.
United States Patent (USP) US 5304314 is disclosed and a kind of is suitable as the sulfur-bearing that antioxidant is used With the phenolic compounds of arylamine.United States Patent (USP) US 2006/0189824A1 discloses a kind of being adapted to As the shielding phenolic compounds containing secondary aromatic amine that antioxidant is used.
But, when the compound of these prior arts is used in two-stroke engine lubricating oil, The high-temperature oxidation resistance of oil product, detergent-dispersant performance energy, abrasion resistance and rustless property are still There is room for improvement.In addition, in addition to the adverse effect of deposit, the rust of electromotor Erosion also can serious curtailment electromotor life-span, and the corrosion of some key positions is in very great Cheng Also the performance of operating condition of electromotor is affected on degree.Prior art to the concern of rustless property also much Not enough.
Therefore, prior art is still required for a kind of two-stroke engine lubricating oil compositionss, its Be not only able to meet current more high standard product is increasingly harsh to high-temperature oxidation resistance will Ask, and also show excellent detergent-dispersant performance energy, abrasion resistance and rustless property.
