Background technology
Foamed aluminium material is loose structure, has that density is little, the feature of lightweight, high specific strength and high-specific surface area, also has the characteristics such as vibration damping, damping, sound-absorbing, sound insulation, heat insulation, electromagnetic shielding simultaneously.But because air spots is sliding, intensity is lower, the range of application of foamed aluminium material is restricted.
Foamed aluminium veneer composite is composited by metal decking and foamed aluminium material (being called for short foamed aluminium core), comprise the foamed aluminium thick china be composited by metal decking and foamed aluminium core, and by the middle foam aluminum sandwich sandwiching one block of foamed aluminium core and form of two pieces of metal deckings.The shortcomings such as foamed aluminium composite material not only has the performance of the many excellences of foamed aluminium material, and the intensity simultaneously also solving single Pao Droplets aluminum is lower, and air spots is sliding.So foamed aluminium composite material is a kind of excellent performance, have the new material of 26S Proteasome Structure and Function concurrently.
The preparation method of current foamed aluminium composite material mainly contains bonded process, method for brazing, diffusion welding (DW) connection method and powder sandwich rolling method etc.Bonded process technique is simple, size accurate, is a kind of method generally adopted at present.But bonded process mainly relies on glue-line to realize the connection of foamed aluminium core and metal decking, to melt at condition lower glue layers such as high temperature, corrosion or pulsating stresses, rotten or aging and cause compound sandwich structural deterioration.Method for brazing and diffusion welding method compensate for the deficiency of bonded process to a certain extent, but method for brazing cost is higher, complicated operation, and because of foamed aluminium core and the impact of oxide-film that exists as the metal aluminum sheet surface of veneer, the solder of soldering is difficult to the oxide-film of elimination surface both and mutually infiltrates on interface, causes bond strength not enough; Diffusion welding method needs higher pressure to realize interface atoms diffusion, but foamed aluminium core is easily out of shape under higher-strength.Powder sandwich rolling method is different from the method for attachment of above-mentioned several foamed aluminium core and metal decking, it is a kind of method of the sandwich structure directly obtained that foamed by precast body high temperature, but the method cost is high, technology is not mature enough, and be difficult to obtain large scale composite board, complex-shaped foamed aluminium composite material can not be produced.
Summary of the invention
The object of the invention is openly a kind of metallurgy method and prepare the method for foamed aluminium veneer composite, it is high that the foamed aluminium composite material that the method obtains has intensity, high temperature resistant, anti-pulsating stress and weatherability, and technique is simple, is suitable for the advantages such as suitability for industrialized production.
In order to achieve the above object, the present invention finds foamed aluminium core and the densification of metal decking surface alumina oxide film, and fusing point is high, it is the principal element affecting metallurgical interface bond quality, therefore, eliminating the alumina layer of faying face, is the key issue of metallurgical compound between foamed aluminium core and metal decking.For this reason, the present invention adopts ultrasonic assisted technique, improves connection in conjunction with covering weave structure, forms good reaction bonded face, and the high-strength metallurgical realized between foamed aluminium core and metal decking connects.
Concrete technology is:
First, treat the oxide layer of gluing of surfaces by machinery or chemical method removing foamed aluminium core and metal decking, and increase surface roughness; Then, in foamed aluminium core and metal decking being placed in, there is the allumen molten bath immersion plating of allumen, make to treat that gluing of surfaces forms uniform allumen immersion plating layer; Then, fit together the foamed aluminium core after immersion plating and metal decking heating, and heating-up temperature is the above 20-50 DEG C of allumen fusing point, and applies the pressure of 0.01MPa or more, and the time of heat-insulation pressure keeping is 5-15 minute; In foamed aluminium core and metal decking heat-insulation pressure keeping process, apply dither or ultrasonic vibration 1-5 minute, dither frequencies is 50-300Hz, and amplitude is 1-3 millimeter; Ultrasonic vibration frequency is 10-30kHz, and amplitude is 10-50 micron.Finally be cooled to room temperature, obtain foamed aluminium veneer composite.
The core of above-mentioned foamed aluminium veneer composite is commercially available all kinds of foam aluminium plate or honeycomb aluminum sheet material;
Above-mentioned metal decking is commercially available arbitrary standards series of aluminium board, or aluminium alloy plate, or sheet metal;
Allumen in above-mentioned allumen molten bath is by the aluminium of 4-35% mass percent, and the copper of 0.1-5% mass percent, the silver of 0-1% mass percent, surplus is zinc composition.
Compared with prior art, beneficial effect of the present invention is:
1, because the present invention is using allumen as connection alloy, and in allumen, add micro Cu and the Ag that can improve adhesive strength, therefore, forming the panel composite joint of high strength simultaneously, foamed aluminium veneer composite joint face also has the mechanical strength higher than foamed aluminium core, and the advantage of high temperature resistant, anti-pulsating stress and weatherability.
2, because the present invention applies dither or ultrasonic vibration as auxiliary in foamed aluminium core and metal decking compound hot pressing, be conducive to the effect strengthening interface cohesion connection, therefore, compared with the foamed aluminium veneer composite obtained with existing method, the mechanical strength of foamed aluminium veneer composite of the present invention is more increased.
