Description

Lubricant compositions
The present invention relates to lubricant compositions, it is stablized by sneaking into the anti-oxidant degraded of some space hindered amine stabilizer.This lubricant compositions is showing excellent results aspect sealing swelling.
United States Patent (USP) 5,073,278 and 5,273,669 have instructed with some aromatic amine and at least one space hindered amine and have carried out stable lubricants composition.
United States Patent (USP) 5,268,113 disclose by adding space hindered amine and phenol and have carried out stable lubricants.
To adding stablizer in the lubricant based on mineral or synthetic oil, with the performance characteristic that improves them, be known.Antioxidant particularly importantly.Due to the existence of high temperature general in the combustion chamber of engine and the nitrogen oxide that serves as oxide catalyst except oxygen, the oxidative degradation of lubricant especially plays an important role in motor oil.
For lubricant, hindered amine compound is effective stablizer.But, due to as deleterious effects such as sealing swellings, conventionally do not adopt them.
The present invention relates to the hindered amine compound stable lubricants composition by a special class.Lubricant compositions of the present invention is for sealing non-corrosiveness.
The present invention relates to stable lubricant compositions, it comprises
The mixture of mineral or synthetic base oil (base oil) or mineral and synthetic base oil; And
The space hindered amine compound of at least one following formula

embodiment
By the following examples, illustrate that space required for protection hindered amine is than the superiority of other similar space hindered amine additive.Supplement enough spaces hindered amine additive to improve total basicnumber to the 5W-30 machine oil containing 0.08%P, described base number is measured by ASTM D4739 by two devices.With the processing horizontal of 1.0wt%, add amine additive A and add amine additive B with 1.2% processing horizontal.At 60 ℃, stir oily 1 hour to guarantee homogeneity.According to elastomer compatibility program CEC-L-39-T-96 test formulations.These formulas are as follows with the result of the CEC-L-39-T-96 test of FKM Viton.Two kinds of amine all affect rubber elastomer.
Figure G2007800284567D00101
Amine A makes it with respect to being not suitable for completely as ACEA specification, use on the magnitude of tensile strength and the impact of ultimate elongation rate.Amine B for the impact of Viton much smaller-show that it is applicable to machine oil.
Amine A is
