Description
Technical field
The present invention relates to a kind of hot rolling lubrication oil composition and use thereof.
Background technology
The hot rolling of Al and Alalloy is carried out at 300 ~ 500 DEG C usually, needs to take away a large amount of heats with emulsion as lubrication and cooling medium, is beneficial to plate form control.This requires that emulsion has outside good lubricity and cooling performance, also requires that emulsion has splendid antiseptic power.In addition, be cost-saving and protection of the environment, also require that emulsion to have in long service life, use procedure the nontoxic odorless not easily feature such as putrid and deteriorated.China's hot rolling emulsion mostly uses the former Soviet Union to fill a prescription or its improvement formula for many years, because its lubricant effect is poor, there is the such as surface imperfection such as black and white bar, sticky aluminium in hot-rolled sheet face, ill effect is caused to the surface quality of finished sheet, aluminium foil, aluminium plate is restricted in the application in the higher field of surface quality requirements.
In recent years along with the development of Chinese national economy and international production are to the transfer of China, China's aluminium hot-work installed capacity unprecedentedly improves, but the hot rolling emulsion used mostly is conventional formulation produces.Document CN1552832A discloses a kind of Novel hot-rolled emulsion be made up of base oil, oleic acid (stearic acid), trolamine, extreme pressure agent, tensio-active agent.Document CN1398291A discloses a kind of, alkylene (C sad by trialkyl phenol, trialkyl phosphates, hexanodioic acid two (2-ethylhexyl) ester, organic aliphatic acid, 5-carbonyl 4-hexyl 2-cyclic ethylene 1-
2-6) glycol, ethoxylation alcohols, trialkanolamine (C
2-4) watersoluble oil composition of the aluminum that forms and aluminum alloy plate materials.Document CN1398293A discloses a kind of by trialkyl phenol, trialkyl phosphates, sulfonated petro-leum, organic aliphatic acid, aminoalkyl alkanediol, trialkanolamine (C
2-4) monoglyceride, four fatty acid pentaerythritol esters, 5-carbonyl 4-hexyl 2-cyclic ethylene 1-are sad, the water-soluble aluminum of ethoxylation alcohols, silica alkyl polymer composition and aluminum alloy hot rolling oil compositions.This kind of hot-rolling oil contains a large amount of fatty acid triethanol amine salt, easily generates greasy filth in use procedure, affects the cleansing performance of milling train and sheet material, seriously constrains the raising of China's aluminothermy rolling production process.
