Abstract
Provided is an ageing heat treatment process of a 3003 aluminium alloy electronic foil. When original hot rolling or cast rolling blank is rolled to be in the thickness of 5.0<+/-0.2>mm, high temperature homogenizing annealing treatment is used, the formation is well-closed, and segregation is weakened. Multi-pass cold rolling is continuously conducted after annealing, and when the thickness of 0.5<+/-0.05>mm is achieved, a complete annealing treatment process is conducted to weaken residual stress. The multi-pass cold rolling is continuously conducted until the thickness of 0.24<+/-0.01>mm is achieved, foil rolling is directly converted, when multi-pass foil rolling reaches the thickness of 0.09<+/-0.005>mm, ageing treatment of 80<+/-5> DEG C *3<+/-0.5> h is conducted, and the control over the morphology and the distribution of the second phase of the aluminium alloy electronic foil blank is achieved. The thickness of a finished product of 0.042mm - 0.038mm is achieved through multiple times of foil rolling after the ageing treatment.

Description
Technical field
The present invention relates to a kind of aging treatment method of 3003 aluminium alloy electronics foil blanks, is mainly to produce
the aging thermal treating process of electronics aluminum foil stock for the aluminium electrolutic capacitor of thickness.
Background technology
The various fields such as that aluminium foil is widely used in is electric, packing, building, and apply range along with the development in epoch and also strengthen, quality product is also had higher requirement.3003 aluminium alloy electronics paper tinsels are a kind of aluminium foils that are widely used in aluminium electrolutic capacitor.Due to complete electronic set, rapidly to short, little, light, thin future development, force aluminium electrolutic capacitor must accelerate miniaturization and microminiaturized process.The key of aluminum capacitor miniaturization is the gigantism of aluminum electrode foil effective surface area, this antianode aluminium foil has proposed to be strict with very much, also require its supporting cathode aluminum foil to possess excellent performance simultaneously, especially the specific capacitance of cathode aluminum foil, because cathode foil for aluminum electrolytic capacitors specific capacitance height affects the size of aluminium electrolutic capacitor volume equally.The aluminium alloy Cathode Foil valency a large amount of a large amount of high-specific capacitance supers of the annual import of China is large, has restricted to a great extent the development of China's electronic industry and the international competitiveness of aluminium processing enterprise.
In 3003 aluminium alloys containing Mn second-phase compound to separate out the alloy Effect on Mechanical Properties very little, but these are weak negative electrode phases containing the Mn precipitated phase for aluminum substrate, can produce the corrosion pit of " cavernous body " shape during chemical etching technology, effectively increase surface-area, be conducive to the raising of electronics paper tinsel specific capacitance.
The approach that improves the aluminum foil stock microstructure is improved the quality of electronics paper tinsel, and reasonably subsequent machining technology is these two.Although 3003 aluminium alloys belong to not heat-treatable strengthened alloy, usually do not carry out timeliness thermal treatment in actual production.
Summary of the invention
Purpose of the present invention: a kind of 3003 aluminium alloy electronics foil blank aging treatment process are provided, can Effective Regulation 3003 finished product aluminum foil stock second-phase forms, achieve evenly, disperse distributes; The 3003 aluminium alloy electronics foil blank corrosion by under this technique, realize the increase of specific capacitance.
The technical solution used in the present invention: aluminum foil stock is realized in the operation of rolling to the combination of high-temperature annealing process, middle Full Annealing technique and timeliness thermal treatment process; In the artificial aging thermal treatment process that the rolling later stage carries out, realized in the 3003 alloy foil operations of rolling control to second-phase form and distribution.
1) by hot rolling blank (cast-rolling stock), be hot-rolled down to

during thickness, carry out
artificial aging is processed, and makes second-phase separate out in a large number, and disperse is uniformly distributed.
4), after multi-pass paper tinsel roll process, select to generate
the aluminium foil of different thickness in scope, generate finished product aluminium alloy electronics foil blank, and this finished product electronics paper tinsel is carried out
the finished product aging treatment process.
By this 3003 aluminium alloy electronics foil blank is implemented to specific thermal treatment process, the present invention realized to the second phase particles in 3003 aluminium alloys (
phase) control of form and distribution, be uniformly distributed its a large amount of disperses, and by using this blank, the later stage corrosive effect is good, improves this aluminium alloy electronics paper tinsel specific capacitance, can reach
.
