Description
Technical field
It is more particularly to a kind of to prepare froth bed using scale effect the invention belongs to composite material rolling technical field
The method of shape foil.
Background technology
At present, there is foam aluminium alloy small density, strong absorption impact capacity, high-damping shock stability and HI high impact energy to inhale
The advantages of yield, sound insulation and noise reduction.Obtain the common concern of scientific circles and industrial quarters.The layer of metallic plate/foamed aluminium/metallic plate formation
Shape result inherits the advantage of foamed aluminium material, and application is had been obtained in fields such as green building, automotive light weight technologies.
As microelectronic, microsecond delay manufacture the fast development in field, people to the demand of very thin stratified material gradually
Increase.However, preparing very thin " metal foil/foam aluminium foil/metal foil " layer using the method for tradition machinery interfacial weld
Shape material has very big difficulty.
The content of the invention
In order to overcome the shortcoming of above-mentioned prior art, bubble is prepared using scale effect it is an object of the invention to provide one kind
The method of foam layer shape foil, using the principle of scale effect occurs in the metal material operation of rolling, prepares high-quality very thin copper
Paper tinsel/foam aluminium foil/copper foil laminar composite, in the case of microcosmic, the material is the stratiform being made up of copper foil and foam aluminium foil
Composite, is that copper and aluminum interfacial weld are intact, not shape in copper foil/foam aluminium foil/copper foil multilayer materials, material
Into intermetallic compound.
To achieve these goals, the technical solution adopted by the present invention is：
A kind of method that utilization scale effect prepares foam stratiform foil, comprises the following steps：
The first step：Using copper foil and aluminium foil as raw material；
Second step：Aluminium foil and copper foil are processed into the sheet material of identical size；
3rd step：Stacked according to copper foil/aluminium foil/copper foil, by being welded product front end soldering；
4th step：The material of front end soldering is subjected to ply rolling；
5th step：Material after ply rolling is taken out, the 4th step is repeated, until foil thickness reaches 10-200 μm.
In the first step, aluminium foil material is commercial-purity aluminium AA1230, and the thickness before copper foil rolling is 100-300 μm, aluminium
Thickness before paper tinsel rolling is 15-50 μm.
In 4th step, single pass reduction ratio is between 40%-60%.
Compared with prior art, the present invention utilizes the scale effect in foil plastic history and high speed plastic deformation
In the case of aluminum alloy materials hole is formed by core of constituent phases, and at the same time, with the reduction of aluminum foil thickness, plastic deformation
Hole ratio present in aluminium foil is gradually stepped up afterwards, so as to become the principle of foam shape.Prepare high-quality ultrathin copper foil/
Foam aluminium foil/copper foil laminar composite.The present invention is adapted to prepare copper foil, aluminium foil and is combined using ply rolling and scale effect technology
Foil, gained composite copper foil/foam aluminium foil/copper foil stratified material has in fields such as microelectric technique, sound insulation and noise reduction, microsecond delays
Bright prospects.

Embodiment
Describe embodiments of the present invention in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the method that the present invention prepares foam stratiform foil using scale effect, flow is as follows：
The first step：It is raw material with copper foil 1 and aluminium foil 2, the thickness before copper foil 1 is rolled is 100-300 μm, before aluminium foil 2 is rolled
Thickness be 15-50 μm.Aluminium foil 2 is commercial-purity aluminium AA1230 foils, and copper foil 1 is general industry copper foil.
Second step：Metal aluminum foil and metal copper foil are processed into the sheet material of identical size.
3rd step：According to copper/aluminium/copper stack obtaining sheet material 3, carried out the front end of the i.e. sheet material 3 of rolled piece by being welded
Soldering.
4th step：Material 4 after soldering is placed between upper lower compression roller 5, ply rolling is carried out, single pass reduction ratio is in 40%-
Between 60%.
5th step：Material is taken out, the 4th step is repeated, material 6 after the foil thickness suitable until reaching is rolled is thick
Degree at 10-200 μm, wherein, roll rear aluminium matrix 7 positioned at rolling for two layers between rear copper material matrix 8, roll has greatly on rear aluminium matrix 7
The hole 9 of amount, but without hole at aluminum bronze interface 10.
The experiment case study of the present invention, uses the thickness of copper foil 1 for 300 μm, and the thickness of aluminium foil 2 is 16 μm.Copper is technical pure
Copper, aluminium is AA1230.Stacked according to such scheme according to copper foil/aluminium foil/copper foil, then, carry out ply rolling.Rolled by 4
After passage processed, the thickness of rolled piece is 160 μm.
Fig. 2 show ply rolling and terminates rear copper/aluminium interface distributions situation, and interface cohesion is intact.
Fig. 3 show AA1230 aluminium alloy microstructures before rolling, and material internal is without hole.
Fig. 4 is shown after ply rolling terminates, the distribution of aluminium alloy microstructure, and there is substantial amounts of nano aperture the inside.
