20%-30%；When accumulation reduction ratio reaches 60%-70%, intermediate annealing need to be carried out, intermediate annealing system is 400 DEG C of annealing
40min, rolling mill practices more than iterative cycles, the thickness before be rolled to finished product needed for a time；
(4) before finished product the annealing process system of passage and last a time finish rolling reduction ratio have to end properties it is critically important
Influence, test before the finished product used annealing process system for：Annealed respectively at 400 DEG C 20min, 40min, 60min, 80min,
100min；320 DEG C to the 440 DEG C 40min that annealed every 20 DEG C to sample, the control of last a time finish rolling reduction ratio 15%~
60%.
The present invention compared with prior art the advantages of be：During cold rolling of the present invention is compound, 30%-50% first rolling pass reduction
Skin material A4045 and core A3003 can be achieved firmly just to combine.Compared with method hot rolling paper tinsel, cold rolling composite insulating foil clad
Transverse gage is more uniformly distributed, and the thickness of upper and lower clad also tends to unanimously；Finish rolling reduction ratio is at 25%~35%, composite insulating foil
Sink-resistance performance it is optimal；The temperature annealed before composite insulating foil finished product should be controlled at 320~400 DEG C, 400 DEG C of annealing, and extension is moved back
The fiery time can improve the sink-resistance performance of composite insulating foil, but more than 80min after, composite insulating foil sagging resistance is deteriorated.

Example IV：
The invention also discloses a kind of production technology of radiator Composite aluminum alloy foil, comprise the following steps：
(1) A3003 alloy cast ingots, A4045 alloy cast ingots are cold-rolled to reality after homogenizing annealing, hot rolling cogging respectively first
Test required specification；
(2) removing surface：The greasy dirt of material surface is cleaned with acetone, rinsed with clear water, dries, is then cleaned with water in steel wire
Surface is polishing on machine and forms sand face effect；
(3) cold rolling compound tense, first rolling pass reduction control exist in 20%-60%, each single pass reduction ratio control afterwards
20%-30%；When accumulation reduction ratio reaches 60%-70%, intermediate annealing need to be carried out, intermediate annealing system is 400 DEG C of annealing

Influence, test before the finished product used annealing process system for：Annealed respectively at 400 DEG C 20min, 40min, 60min, 80min,
100min；320 DEG C to the 440 DEG C 40min that annealed every 20 DEG C to sample, the control of last a time finish rolling reduction ratio 15%~
60%.
When reduction ratio is 25%~35% or so, composite insulating foil has good sink-resistance performance.Reduction ratio it is too low or
Too high, its sagging performance can all reduce to some extent.This is due to the too small recrystallization that can improve finished product composite insulating foil of reduction ratio
Temperature so that recrystallization process carries out not exclusively before the fusing of skin material during high temperature brazing, and the Si elements in skin material can be along not
The crystal boundary for completing recrystallization region is largely diffused into sandwich layer, and the tensile strength and sink-resistance performance for making composite insulating foil drastically reduce.
If reduction ratio is too high, crystallite dimension can be caused to attenuate, crystal boundary increases.It is substantial amounts of brilliant under the condition of high temperature during composite insulating foil soldering
Boundary can produce creep, so that the sink-resistance performance of composite insulating foil deteriorates rapidly.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
