The annealing cleanness of aluminium rolling oil is meant under annealing temperature, oil product will be rapidly from aluminium sheet or aluminium foil surface volatilization, do not stay any vestige, be that product surface does not have spot, this just requires base oil must have suitable viscosity, narrower boiling range scope, and when the structure of compound and base oil adapt, just compatibility preferably can be arranged, also could guarantee the annealing cleanness of oil product, in addition, base oil has higher flash-point, is the essential condition that guarantees the aluminium rolling safety in production.For the base oil in the present composition, it is characterized in that the boiling range scope less than 70 ℃, 40 ℃ of kinematic viscosity are 1.0～4.0mm
2/ S.Fatty Alcohol(C12-C14 and C12-C18) (A) can be preferably the R in its general formula
0Be the alkyl with 8～16 carbon atoms, fatty acid ester (B) can be preferably the R in its general formula
1Be alkyl with 8～18 carbon atoms, R
2It is compound with 1～4 carbon atom alkyl.
Composition stable in properties proposed by the invention, and have good annealing cleanness and resistance to abrasion.Total add-on of Fatty Alcohol(C12-C14 and C12-C18) (A) and fatty acid ester (B) is 1～10m% of aluminium rolling oil composition, and surplus is a base oil.Wherein the consumption of component (B) can be 10～90m% of component (A) and component (B) total mass.Rolling oil composition for rolling aluminium foil is preferably 50～90m%; Rolling oil composition for Rolling Aluminium Plate is preferably 10～50m%.When component (B) mass percent exceeds this scope, can influence the annealing cleanness and the resistance to abrasion of aluminium rolling oil, usually the oil film strength of aluminium rolling oil is 235.2 to 294.0N, annealing cleanness is 2～4 grades, the composition oil film strength that the present invention proposes is 274.4～343.0N, and annealing cleanness is 1～2 grade.
Further aim of the present invention is when guaranteeing good annealing cleanness and resistance to abrasion, improves the antioxidant property and the safety in utilization of oil product.
Aluminium rolling oil recycles at a certain temperature for a long time, and with processing aluminium material surface be in tight the contact with aluminium powder, under the katalysis of aluminium, the oxidation meeting of hydro carbons is quickened greatly, generate some acids and other carbonyl compound, acid number is raise, and annealing cleanness degenerates, the quality of influence of rolled product.Add an amount of oxidation inhibitor as can be seen by table-1 and can make oil product have good oxidation-resistance, guarantee the annealing cleanness of product.
