[ solution ] A lubricating oil composition which contains a base oil (A) containing an aromatic ester compound (A1) having a specific structure and having a straight-chain alkyl group having 6 to 12 carbon atoms, and which contains 40 to 500 ppm by mass of a phosphorus compound (B) in terms of phosphorus atoms, wherein the phosphorus compound (B) is selected from the group consisting of an acid phosphate ester (B1) having an alkyl group having 1 to 8 carbon atoms and an amine salt (B2) of the acid phosphate ester.
Description
Technical field
The present invention relates to the application method of lubricant oil composite and lubricant oil composite.
Background technology
The portions such as the chain, roller chain, chain conveyor, the roller that possess for devices such as high temperature furnace, drying oven, heat setters
The lubricant oil composite of part requires it heat resistance (particularly low vapo(u)rability) due to being exposed to high temperature.If for example,
Lubricant oil composite is used in high temperature environments, then the lubricant oil composite loses viscosity, is formed at the lubricating oil of parts surface
The easy filming of overlay film of composition, further, the evaporation capacity increase of lubricant oil composite are also resulted in significantly to the life-span of device
Influence.
It is therefore desirable to which the evaporation capacity under hot environment and the high temperature lubricating oil composition with excellent heat resistance can be suppressed
Thing, various lubricant oil composites are proposed in order to tackle the requirement.
For example, Patent Document 1 discloses to provide aromatics of the content comprising Parleam and with specific structure
The high temperature oil of ester, it is used to lubricate the chain of continuous press, sprocket wheel and band.

Patent document 1：Japanese Unexamined Patent Application Publication 2014-515412 publications.
The content of the invention
Problems to be solved by the invention
Wood chip, lumber fibre class are mixed with heated bonding agent however, the wood panel used in building, furniture etc. passes through
Compound is suppressed to manufacture at high temperature.In the manufacture of wood panel, from the viewpoint of production efficiency is improved, work is used
For the continous way wood panel pressure setting of continuous-production-type device.
Roll conveyor above and below the device use make wood raw material, shaping after wood panel be heated to 200 DEG C with
On pressure setting in move.The roll conveyor has the structure of roller by chain coupling circlewise, and the roller is heated paramount
The pressure setting interior circulation of temperature, therefore it is constantly exposed to the condition of high temperature.
In addition, the driving of the roller of marshalling is conducted via the thin bar-shaped rod inserted from the two ends of roller, inserted with rod
Roller rotated by axle of the rod.In order that roller rotates well, supplied to the gap (hereinafter also referred to " roller rod part ") of roller and rod
To lubricant oil composite.
However, the narrow gaps of roller rod part, the lubricant oil composite that can be supplied to roller rod part is only micro.This
Outside, it is the portion for being particularly easy to generate heat and more easily reach high temperature than heating furnace that roller rod part is caused due to the high-speed driving of rod
Position.
And then, in order to further improve productivity ratio, it is desirable to the high speed of roll conveyor, accompany with this, rod is applied
Load, rotating speed also become big.In addition, according to the difference of used bonding agent species, it is also anticipated that may require that in lower progress at higher temperature
Heating, temperature conditionss become harsher.
High temperature described in patent document 1 is used for chain, sprocket wheel and band with oil, if compared with above-mentioned roller rod part,
It can be described as being difficult to reach a high temperature and also can ensure that the position of sufficient quantity delivered.
It can be seen from the research of the present inventor：Such conventional high temperature described in patent document 1 is used with lubricant oil composite
When above-mentioned roller rod part, because temperature is high and can not fully supply lubricant oil composite, therefore the easy seizure for occurring rod,
Rod to lose frequency high.
Therefore, seek compatibly can easily reach a high temperature as above-mentioned roller rod part and can not be sufficiently fed profit
The lubricant oil composite used between the part of sliding oil composition.
It is an object of the present invention to provide lubricant oil composite, it is even in easily reaching a high temperature and can not be sufficiently fed
Used between the part of lubricant oil composite, evaporation capacity is also reduced, and the effect that suppression sludge is produced is also high, and with excellent
Heat resistance, while excellent greasy property can also be shown.
