Description
Technical field
The present invention relates to metal foaming technical field, and in particular to a kind of composite foamed sheet material that can be used as construction wall.
Background technology
Porous foam metal material is made up of metallic framework and hole, is a kind of function material that recent decades grow up
Material.Since the advent of the world, as structural material, it has the characteristics of lightweight, high specific strength；As functional material, it have it is porous,
Vibration damping, damping, sound-absorbing, sound insulation, radiating, impact energy, a variety of physical properties such as electromagnetic shielding are absorbed, furthermore its recyclable spy
Point, the needs of current development are adapted to, at home and abroad general industry field and high-tech sector have obtained more and more extensive answer
With.
The porous foam metal material having been developed that at present has foamed aluminium (and foam aluminium alloy), nickel foam, foam zinc, bubble
Foam lead, titanium foam, foam cast iron and blister steel etc., the research of wherein foamed aluminium is the most ripe, and shows in actual applications
Wide prospect.Foamed aluminium is after adding additive in pure aluminum or aluminum alloy, to be formed by foam process, while have metal concurrently
With bubble feature.Its density is small, high-selenium corn impact capacity is strong, high temperature resistant, fire protecting performance are strong, anticorrosive, sound insulation and noise reduction, thermal conductivity
It is low, electromagnetic wave shielding is high, weatherability is strong, have filter capacity, easy processing, easy to install, forming accuracy is high, can carry out external coating.
Chinese patent discloses (bulletin) number：CN104404287B discloses a kind of using foamed ceramics auxiliary production foamed aluminium
Process.Certain size, density, the foamed ceramic particle of porosity are made, while by foamed ceramic particle and foamed aluminium
TiH used2Blowing agent powder is mixed, and powder is fully incorporated in the hole of foamed ceramics.During foamed aluminium is produced, it will be stained with
There are the ceramic particle of blowing agent powder and blowing agent powder while add in aluminum solutions, can preferably improve foaming process.Together
When, the foaming agent in foamed ceramics particle relies on ceramic particle outwards to produce gas, coarse on the outside of ceramic particle, while itself has
There is certain gravity, therefore be not easy to float, driven the tiny bubble of surrounding to be not easy to float.Solves the production of conventional melt foaming
The problem of Aluminum Foam bubble floating causes porosity uneven.
Above-mentioned this method, pottery ball incorporation are difficult to uniformly, and incorporation is few, complex process.Simultaneously because foaming agent reaction is acute
The strong quick stirring of needs, and stirring slurry tooth easily smashes foam pottery ball particle when quickly stirring, and influences homogeneous quality.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of cost low, and lightweight, high-strength can be used as construction wall
Composite foamed sheet material.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of composite foamed sheet material that can be used as construction wall, including a foam aluminium plate, in the foam aluminium plate
Pottery ball is provided with, the pottery ball is enclosed in inside foam aluminium plate, and is mutually not in contact with each other between each pottery ball.
Above-mentioned pottery ball adds in foam aluminium plate foaming process, the foaming together with foamed aluminium, by foamed aluminium
Wrapped up；Pottery ball is added in foamed aluminium as packing material, reduces the weight of sheet material, while be greatly reduced cost.
Above-mentioned pottery ball selection light-weight foam pottery ball, particle diameter is in 0.1-3cm, and pottery ball cost is low, light weight, and manufactured sheet material is inhaled
Energy effect is good, and bulk strength is high.
Above-mentioned pottery ball is hollow-core construction.
The thickness of above-mentioned composite foamed sheet material, can be directly as wall board in 4cm or so, and the thickness of traditional non-load bearing wall
The usable floor area of interior can be increased in 24cm or so using above-mentioned sheet material by spending.
The processing method of above-mentioned composite board is as follows：
(1) it is incorporated into after the aluminium liquid of molten condition being added into foaming agent in foaming mould；
(2) pottery ball is first cooled down and (is long placed in) to normal temperature, then rapid heating, raise pottery spherical surface temperature, to approach metal
The temperature of liquid is preferred；Pottery ball quickly heats, and because having cavity inside pottery ball, makes its surface temperature high, internal temperature is low, realizes fast
Quickly cooling but foam metal body (inner cold technology), foaming is more above caused by preventing bubble up, few uneven ask of foaming below
Topic；
(3) with bottomless metal net shaped basket (being easy to be vented), turn around and fill with pottery ball, with plastics netting back cover, then turn around
Down, basket press-in is immersed into foaming mould for bottom, conventional method foaming, basket is proposed when half solidification；Or directly will
Pottery ball is sprinkled into aluminium liquid, is stirred using agitating device, pottery ball is suspended in aluminium liquid；
Plastics netting is disappeared with high temperature melting after molten metal contacts, and pottery ball is pressed into molten metal, between ball of making pottery mutually
Contact, it is evenly distributed, the dosage for improving pottery ball is maximized, foamed aluminium dosage is reduced, reduces cost；
(4) after cooling down, the metallic plate for completion of being foamed in mould is taken out and can obtain foam metal plate.
Above-mentioned metal net shaped basket is pressed into molten metal using external pressure.
The volume ratio of above-mentioned molten metal and pottery ball is 35：65, optimal performance and economic performance can be reached.
The mode of heating of above-mentioned pottery ball is directly heated or is sent into electric heating equipment for pyrogenic process and heats.
The foamed aluminium material that present invention process is produced is processed into 10mm heavy-gauge sheetings, after testing, energy-absorbing density：20~26J/
cm3；Intensity：≥10Mpa；Noise reduction coefficient NRC more than 0.8 (foam aluminium plate noise reduction coefficient 0.6).
The beneficial effects of the invention are as follows：
(1) technical scheme changes conventional foam aluminium foaming structure, increase filling chock material pottery ball, the sheet material tool of preparation
Have heat-insulated, fire prevention, lightweight is high-strength, moistureproof, radiation proof, is easily installed, inexpensively, renewable；
(2) by using special processing mode to pottery ball, it is that bubble pressure upstream is big in foaming process, is just uniformly distributed
In aluminium liquid, so as to reduce the uniformity that bubble is up and aluminium liquid is sunk, and raising foamed aluminium foams；
(3) it is high to change traditional pure foam aluminium cost, it is difficult to which, as construction material, maximization reduces cost；
(4) composite of the present invention uses solid space structure, mutually support, rigid mutually to be made up with soft.
