Description
Technical field
The present invention relates to aluminium processing fluid composition (lubricant for aluminum processing composition).
Background technology
Aluminium radiator fin is used in the heat exchanger of the freezing and refrigerating system of refrigerator, air-conditioning etc..Aluminium radiator fin passes through to flat
The al member (aluminum heat radiation sheet) of tabular carries out protruding processing, deep-draw processing, Punching Technology, stample fiber, thinning drawing processing
Manufactured Deng plastic working etc..The processing of these aluminum heat radiation sheets is carried out usually using finish.As finish, different alkane is used
The synthesis such as hydrocarbon are hydrocarbon (for example, referring to patent document 1).
Being attached to the finish of aluminum heat radiation sheet after processing needs to remove by heating.It is therefore desirable to finish has one
Determine the volatility of the above.If however, making the volatility of finish good, finish volatilizees, can not obtain foot before processing, in processing
Enough processabilities.In addition, when as the keeping of the aluminium radiator fin of machined material, conveyance, assembling processing between aluminium radiator fin
Lubricity deficiency when the reason for directly contacting and hindering as generation or assembling.On the other hand, if in order to prevent these from bad making
With not volatile finish, then degreaser can not be fully removed in finish removing step.
It is therefore desirable to finish is not volatile at room temperature, rapidly and is filled under the design temperature of finish removing step
Divide performance opposite as ground volatilization.In addition, from prevent foul smell, operator skin it is roughening etc. from the viewpoint of, it is expected
The inexcessive high finish of volatility.Therefore, take base oil to use readily volatilized solvent, made up by the use of additive
The countermeasure of processability.However, additive also requires high volatile, therefore the scope selected is narrow, and conventional finish can not be said completely
Meet the characteristic of above-mentioned requirements.

The content of the invention
Problems to be solved by the invention
The present invention be in view of such actual conditions form, its object is to, there is provided there is enough degreasers, simultaneously
Even and if to limit the aluminium that the additive of scope can also play enough processabilities, foul smell, skin can be prevented roughening etc.
Processing lubricating oil.
The solution used to solve the problem
In order to solve the above problems a little, further investigation is repeated in the present inventor, as a result finds by using with specific
The hydrocarbon ils of character, so as to play the effect of additive to greatest extent, so as to obtain that degreaser and processability can be made
Such opposite performance reaches the good aluminium of balance with high level and processes fluid composition, so as to complete the present invention.
That is, the present invention relates to a kind of aluminium to process fluid composition, it is characterised in that it contains the mass % of hydrocarbon ils (A) 90~99
With the mass % of oiliness improver (B) 1~10,5% recovered (distilled) temperature of the hydrocarbon ils (A) is more than 190 DEG C, 95% recovered (distilled) temperature is 255
Below DEG C and the difference of 5% recovered (distilled) temperature and 95% recovered (distilled) temperature is less than 45 DEG C, comprising being calculated as 90 mass % with hydrocarbon ils benchmark
Alkane hydrocarbon system hydrocarbon above, the oiliness improver (B) are selected from ester, monohydric alcohol and carboxylic acid.
The effect of invention
The aluminium processing fluid composition of the present invention enables high degreaser and processability to reach balance good, and press down
Foul smell processed, skin irritatin, the Health cost for suppressing operator is also contributed.
Embodiment
Hereinafter, it is described in detail for the present invention.
The aluminium processing fluid composition (hereinafter referred to as processing fluid composition) of the present invention contains hydrocarbon ils (A), the hydrocarbon ils (A)
