Abstract
Provided are a lubricating oil composition having excellent brake squeal prevention performance, and a lubricating method using the same. A lubricating oil composition containing a base oil (A) and a specific hydroxyl group-containing amine compound (B), and a lubricating method using the same.
Description
Technical field
The present invention relates to lubricant oil composite and use its lubricating method.
Background technology
Conventional industrial machinery, such as agricultural machinery, construction implement, Transport Machinery in, have speed changer (gear), oil
Actuation part etc. is pressed, to the lubricant oil composite used in industrial machinery, it is desirable that prevent speed changer seizure and abrasion, for maintaining
The viscosity characteristics etc. of oil pressure output power.In addition, these industrial machineries in outdoor progress with the operation of high-output power, therefore
The stability also required oxidative degradation to heat and water is not required nothing more than.
Among industrial machinery, such as the agricultural machinery such as tractor, rice transplanter, reaper binder, combine harvester, oil pressure excavate
The Transport Machinery such as the construction implements such as machine, crane, bull-dozer, dumper, fork truck, shovel loader, full landform transport vehicle are also equipped with wet type
Brake, speed changer (gear), oil pressure activated portion and the wet brake that these machineries have are generally with identical lubrication
The shared lubrication that fluid composition is lubricated.For example, as the lubricant oil composite used in agricultural machinery, it is proposed that include choosing
From the lubricant oil composite of one or more of zinc dialkyl dithiophosphate, alkaline calcium sulfonate and alkaline calcium phenates (such as
Referring to patent document 1).
Existing technical literature
Patent document
Patent document 1:Japanese Unexamined Patent Publication 2009-144097 bulletins.
Invention content
The subject that the invention solves
However, as problem peculiar in wet brake, exist attached due to the rubbing surface because being iteratively produced between rubbing surface
It and slide, the brake i.e. caused by stick-slip caused by vibration etc. screams.Therefore, to being also equipped with the industry of wet brake
The lubricant oil composite used in machinery, special requirement prevent performance (hereinafter referred to as " anti-the screaming property of brake that brake screams
Can ").
However, in lubricant oil composite disclosed in Patent Document 1, it cannot be satisfied anti-brake and scream performance, it is desirable that is full
The anti-brake of foot screams the technological development of performance lubricant oil composite.
The present invention carries out in view of the foregoing, particularly, and it is an object of the present invention to provide having excellent anti-screaming property of brake
Can lubricant oil composite and use its lubricating method.
Means for solving the problems
It is that the inventors of the present invention are furtherd investigate repeatedly as a result, it has been found that, can solve the above subject by following inventions.That is, this hair
It is bright that the lubricant oil composite with following compositions is provided and uses its lubricating method.
1. lubricant oil composite contains:The amine compounds of hydroxyl shown in base oil (A) and the following general formula (1)
(B),
[Chemical formula 1]
(in general formula (1), R1It is the aliphatic alkyl that carbon atom number is 12 ~ 30, R2And R3Be each independently carbon atom number be 1 ~ 5
Aliphatic alkyl).
2. lubricating method, wherein use the lubricant oil composite described in above-mentioned 1.
The effect of invention
According to the present invention, it is particularly capable of providing the lubricant oil composite that there is excellent anti-brake to scream performance and uses
Its lubricating method.
Specific implementation mode
[Run Huayouzuhewu ]
Hereinafter, being illustrated for embodiments of the present invention (hereinafter also referred to " present embodiment ").
The lubricant oil composite of present embodiment contains the amination of hydroxyl shown in base oil (A) and the following general formula (1)
Close object (B).Hereinafter, being illustrated for each ingredient.
[Chemical formula 2]
(in general formula (1), R1It is the aliphatic alkyl that carbon atom number is 12 ~ 30, R2And R3Be each independently carbon atom number be 1 ~ 5
Aliphatic alkyl).
(base oil (A))
It can be mineral oil as the base oil (A) used in the lubricant oil composite of present embodiment, or synthesis
Oil.
As mineral oil, can enumerate:The crude oil of alkane base system, cycloalkane base system, intermediate base system is subjected to normal pressure steaming
Atmospheric resids obtained from evaporating;Distillate oil obtained from the atmospheric resids are evaporated under reduced pressure;The distillate oil is subjected to solvent
Depitching, solvent extraction, be hydrocracked, solvent dewaxing, catalytic dewaxing, one or more of hydrofinishing etc. processing and refine
Obtained mineral oil, such as light neutral oils, middle matter neutral oil, heavy neutral oil, bright stock;And to passing through the systems such as fischer tropsch process
The wax (GTL waxes) made carries out mineral oil etc. obtained from isomerization.
In addition, as mineral oil, can for be classified as in the base oil classification of API (American Petroleum Institute) 1 class, 2 classes,
The mineral oil of any one in 3 classes, from obtain anti-brake scream performance, in addition inhibit sludge formation, obtain excellent speed changer
Seizure and abrasion prevent performance, viscosity characteristics, to the stability of oxidative degradation etc. from the perspective of, be preferably classified as
The mineral oil of 2 classes, 3 classes.
As synthetic oil, it can be cited for example that polybutene, ethene-alpha-olefin copolymer, alpha-olefin homo or copolymer
Equal poly alpha olefins;The various esters such as polyol ester, dibasic acid ester, phosphate;The various ethers such as polyphenyl ether;Polyethylene glycol;Alkylbenzene;
Alkylnaphthalene etc..
It for the viscosity of base oil (A), is not particularly limited, the seizure of scream from anti-brake performance and speed changer
With abrasion prevent performance, viscosity characteristics, to the stability of oxidative degradation etc. from the perspective of, the kinematic viscosity at 100 DEG C is excellent
It is selected as 2 ~ 25mm2The range of/s, more preferably 3 ~ 20mm2The range of/s, further preferably 4 ~ 15mm2The range of/s.
In addition, the viscosity index (VI) of base oil (A) from anti-brake scream performance and speed changer seizure and abrasion it is anti-
