The invention discloses a special long-acting 
cutting fluid for aluminum 
alloy, and mainly relates to the technical field of 
metal cutting fluids, the special long-acting 
cutting fluid comprises the following components by 
mass percentage: 46 # 
machine oil 12%-13%; AC28, 1%-2%; CP-50, 3%-4%; 1.5%-3.0% of a bactericide; 4%-5% of 
glycerol; 45%-55% of water; 3.5%-4.5% of 
sodium nitrite; T-80, 4%-5%;S-80, 7%-9%; JHP-E9600, 1.5% 3.0%; T706, 0.15%-0.2%; 1%-2% of 
triethanolamine; 0.1%-0.2% of a defoaming agent; 7%-8% of 
triethylene glycol butyl 
ether; microemulsions are more stable, better 
hard water resistace is achieved through anion-free design, a prepared 
diluent is effective for a long time, the 
diluent is still effective after mechanical oil is separated out, cutting is not affected, cleaning is not needed, the second set of wonderful lubricating scheme enables a user to use the 
machine all the time, the purpose that the cost of the user is reduced is achieved, energy is saved, the maintenance cost is low, the cleaning period is long, and a large number of raw materials are saved.
