Description
Technical field
The invention belongs to composite material rolling technical fields, in particular to a kind of to prepare froth bed using scale effect
The method of shape foil.
Background technique
Currently, foam aluminium alloy has, density is small, absorb impact capacity by force, high-damping shock stability and HI high impact energy are inhaled
The advantages that yield, sound insulation and noise reduction.Obtain the common concern of scientific circles and industry.The layer that metal plate/foamed aluminium/metal plate is formed
Application has been obtained in fields such as green building, automotive light weight technologies in the advantages of shape result inherits foamed aluminium material.
With the fast development of microelectronic field, microsecond delay manufacturing field, demand of the people to very thin stratified material is 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.
Summary of the invention
In order to overcome the disadvantages of the above prior art, scale effect preparation bubble is utilized the purpose of the present invention is to provide a kind of
The method of foam layer shape foil prepares the very thin copper of high quality using the principle that scale effect occurs in the metal material operation of rolling
Foil/foam aluminium foil/copper foil laminar composite, in microcosmic situation, which is the stratiform being made of copper foil and foam aluminium foil
Composite material is copper foil/foam aluminium foil/copper foil multilayer materials, and in material, copper and aluminum material interfacial weld are intact, not shape
At intermetallic compound.
To achieve the goals above, the technical solution adopted by the present invention is that:
A method of foam stratiform foil being prepared using scale effect, is included the following steps:
Step 1: using copper foil and aluminium foil as raw material；
Step 2: aluminium foil to be processed into the sheet material of identical size with copper foil；
Step 3: being stacked according to copper foil/aluminium foil/copper foil, by being welded product front end soldering；
Step 4: the material of front end soldering is carried out pack rolling；
Step 5: material after pack 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, before copper foil rolling with a thickness of 100-300 μm, aluminium
Foil rolling before with a thickness of 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 and high speed plastic deformation in foil plastic history
In the case of aluminum alloy materials by core of constituent phases form hole, and at the same time, with the reduction of aluminum foil thickness, plastic deformation
Hole ratio present in aluminium foil is gradually increased afterwards, to become the principle of foam shape.Prepare the ultrathin copper foil of high quality/
Foam aluminium foil/copper foil laminar composite.The present invention is suitble to prepare copper foil, aluminium foil compound using pack rolling and scale effect technology
Foil, gained composite copper foil/foam aluminium foil/copper foil stratified material have in fields such as microelectric technique, sound insulation and noise reduction, microsecond delays
Bright prospects.

Specific embodiment
The embodiment that the present invention will be described 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, process are as follows:
Step 1: be raw material with copper foil 1 and aluminium foil 2, copper foil 1 roll before with a thickness of 100-300 μm, before aluminium foil 2 rolls
With a thickness of 15-50 μm.Aluminium foil 2 is commercial-purity aluminium AA1230 foil, and copper foil 1 is general industry copper foil.
Step 2: metal aluminum foil to be processed into the sheet material of identical size with metal copper foil.
Step 3: being stacked to obtain sheet material 3 according to copper/aluminium/copper, the front end of rolled piece, that is, sheet material 3 is carried out by being welded
Soldering.
Step 4: the material 4 after soldering is placed between upper lower compression roller 5, pack rolling is carried out, single pass reduction ratio is in 40%-
Between 60%.
Step 5: material is taken out, the 4th step is repeated, the material 6 after reaching suitable foil thickness and being rolled is thick
Degree is at 10-200 μm, wherein rolls rear aluminium matrix 7 and rolls between rear copper material matrix 8 positioned at two layers, roll has greatly on rear aluminium matrix 7
The hole 9 of amount, but without hole at aluminum bronze interface 10.
An experiment case study of the invention, using copper foil 1 with a thickness of 300 μm, aluminium foil 2 is with a thickness of 16 μm.Copper is technical pure
Copper, aluminium AA1230.It is stacked according to above scheme according to copper foil/aluminium foil/copper foil, then, carries out pack rolling.It is rolled by 4
After passage processed, rolled piece with a thickness of 160 μm.
Fig. 2 show copper/aluminium interface distributions situation after pack rolling, and interface cohesion is intact.
Fig. 3 show AA1230 aluminium alloy microstructure before rolling, and material internal is without hole.
After Fig. 4 show pack rolling, the distribution of aluminium alloy microstructure, there is a large amount of nano aperture in the inside.
