Material.
Background technique
Foam metal material and metal-based compound foam have low-density, high specific pressure contracting intensity, high specific stiffness, high-damping,
Many excellent physical characteristics such as high-wearing feature, high-fatigue strength, low thermal coefficient of expansion, to prepare light structure, high energy-absorbing, sound absorption
Equal functional materials provide possibility.The porous materials such as the foam metal material and metal-based compound foam developed at present are
Started to reduce safety wind as good shockproof energy-absorbing material applied to fields such as automobile, aviation, national defence, public safeties
Danger.But with the development of science and technology, high speed HI high impact collision equipment is more and more, and most of foam metal and Metal Substrate are multiple
It closes the energy-absorbing of foamed material, have been unable to meet the demand of the security performances such as anticollision damping than energy-absorbing, energy absorbing efficiency.
Zinc and kirsite are mainly used in protective coating, corrosion-resistant material, anticollision damping, wearing piece, reduction gearing revolution
The fields such as kiln Supporting annulus.The specific gravity of kirsite is higher, and application range is also narrow, and the overwhelming majority is applied to anti-corrosion and coating is led
Domain.Improve the high characteristic of kirsite specific gravity, expanding seems critically important using kirsite range.
Summary of the invention
It is an object of the present invention to provide the zinc-base composite foam materials of different ratio.
In order to achieve the above objectives, as follows using technical solution:
A kind of zinc-base composite foam material, matrix are Zn-Al-Cu-Mg alloy, and certain volume score is added in melting
Hollow glass micropearl, stirring evenly spread to hollow glass bead in matrix.
The zinc-base composite foam material chemical component is according to mass percent are as follows: Zn 82%-92%, Al 5%-
20%, Mg 0.5-3%, Cu 1-2%；According to volume fraction percent, hollow glass bead 5-70vol.%, partial size 50-
100μm。
According to volume fraction percent, hollow glass micropearl 5-70vol.%.Specific way is first progress matrix melting,
Calculate matrix density, volume is calculated according to matrix density, weighs the hollow glass micropearl of respective volume.
According to said ratio, fusion process are as follows: melt zinc with the graphite crucible that medium frequency induction melting furnace heating blanket is protected；
It is warming up to 650-700 DEG C after zinc fusing, aluminium and copper is added, keeps the temperature 8-10 minutes；It is stirred after aluminium copper and aluminium block fusing equal
It is even, it is then cooled to 500-550 DEG C, the magnesium plate of aluminium foil package is added, keeps the temperature 2-3 minutes；Alloy liquid is stirred with blender, is turned
Speed is 400-800r/min, and hollow glass micropearl is added, and is stirred 3-8 minutes, cooling and demolding.
According to above scheme, hollow glass micropearl is fully entered in alloy, forms the zinc-base composite foam of hole-closing structure.
According to above scheme, zinc-base composite foam material density is reduced to 3.4-5.8g/cm3, porosity can reach
55%, it can reach 36.0KJ/m than energy-absorbing3, energy absorbing efficiency can reach 67.5%, and average platform stress reaches as high as
To 238MPa.
The present invention is tested using the aluminium content and different volumes score cenosphere of heterogeneity ratio.Fusion process
It is middle to use same process, quasistatic compression test is carried out after processing on universal testing machine.
Zinc-base composite foam material prepared by the present invention, the feature of existing common composite foam material, and due to hollow glass
The hole-closing structure of glass microballon, improves the uniformity, consistency, integrality of material, and performance is improved.
The beneficial effects of the invention are that:
The method that present invention preparation uses smelting furnace melting and casting zinc-base composite foam, simple process produce quick, matrix
Can with coated hollow glass bead, can according to different ratio change ingredient melting, be suitble to factory's industrialization production；
Zinc-base composite foam material prepared by the present invention improves the high deficiency of zinc alloy material specific gravity, and kirsite is utilized
Distinctive vibration damping and energy-absorbing performance, so that the anticollision damping energy absorption performance of metal-based compound foam has raising by a relatively large margin.By
It is low in hollow glass micropearl density, have complete core-shell structure, therefore compared to foaming preparation metal-based foam material,
Zinc-base composite foam material is higher in low density while structural integrity, intensity；
Zinc-base composite foam material prepared by the present invention disperses in the alloy, there is nucleocapsid cavity knot due to hollow glass micropearl
Structure and high porosity feature, thus have vibration and noise reducing, high damping characteristic, reduce density, etc. good characteristics.Efficiently solve zinc
The narrow disadvantage of the application range of alloy.
