Description
Technical field
The present invention relates to aluminum alloy materials fields, and aluminium foil is eaten more particularly to novel antibacterial.
Background technology
Existing to be applied to air-conditioning duct, heat exchanger, the antibacterial aluminium foil of Key works Drug packing is all utilized in aluminium foil surface painting
Cloth antimicrobial coating achievees the effect that antibacterial, and the product with antibacterial ability is also seldom in itself in edible aluminium foil field.In aluminium foil
Antimicrobial coating the hidden danger of microbial contamination, and the production of antibiotic paint are inevitably present in production and packaging process
Cost is higher；In order to reduce contaminated degree, to the purity requirements higher of workshop.If it is possible to it develops
Itself has the edible aluminium foil of antibacterial ability, can simplify production technology, improves production efficiency, reduces cost.
The content of the invention
Present invention is primarily aimed at a kind of novel antibacterials of proposition to eat aluminium foil, to solve above-mentioned aluminium existing in the prior art
It paper tinsel surface, may contaminated technical problem in production and packaging process in itself without antibacterial action.
For this purpose, the present invention proposes that novel antibacterial eats aluminium foil.On the basis of 8079A aluminium alloys, the present invention is in aluminium foil
In preparation process, a certain amount of Cu elements are added in molten aluminum, and combine heat treatment, aluminium foil surface is made to be analysed to inner homogeneous disperse
Go out fine copper-rich phase, make it have antibacterial ability, aluminium foil is eaten so as to obtain novel antibacterial.In use, aluminium foil surface
On copper-rich phase constantly can dissolve copper ion, and copper ion is with positive charge, when copper ion touches the cell of microorganism
During film, Coulomb attraction effect occurs with negatively charged cell membrane, makes the two strong bonded, copper ion penetration cell film enters thin
It reacts with sulfydryl, the amino on bacterium internal protein etc. in bacterium.And the activated centre of cell synzyme is by containing sulfydryl, ammonia
The functional groups such as base, hydroxyl form, and the protein active center is destructurized after being combined with copper ion, cause microorganism dead
Or division growth ability is lost, bacterium or microorganism cannot be grown on surface, so as to reach antibacterial effect.In addition, add simultaneously
Add a certain amount of Y element, make Y element and Cu element collective effects, improve the antibiotic property of aluminium foil.Actually Y element also has in itself
There is certain antibacterial ability, the content of the in vivo important meals element of bacterium, such as Ca elements can be influenced, so as to influence bacterium
Normal physiological activity, its growth breeding is caused to be suppressed, it is last dead, so as to reach antibacterial effect.
For this purpose, the present invention uses following technical scheme：
Novel antibacterial eats aluminium foil, including following component：Si, Fe, Cu, Mn, Mg, Zn, Ti, Y, remaining is Al and can not keep away
The impurity exempted from.
Further, the novel antibacterial eats aluminium foil, and the mass percent of each ingredient is：Si：≤ 0.16%, Fe：
0.80~1.70%, Cu：0.10~0.17%, Mn：≤ 0.4%, Mg：≤ 0.04%, Zn：≤ 0.06%, Ti：≤ 0.06%,
Y：0.05~0.10%, each ＜ 0.05% of other impurities element, impurity element adds up to ＜ 0.15%, surplus Al.
Further, the novel antibacterial eats aluminium foil, and the mass percent of each ingredient is：Si：≤ 0.14%, Fe：
0.90~1.60%, Cu：0.11~0.16%, Mn：≤ 0.3%, Mg：≤ 0.03%, Zn：≤ 0.04%, Ti：≤ 0.04%,
Y：0.06~0.09%, each ＜ 0.05% of other impurities element, impurity element adds up to ＜ 0.15%, surplus Al.
Further, the novel antibacterial eats aluminium foil, and the mass percent of each ingredient is：Si：≤ 0.13%, Fe：
1.00~1.60%, Cu：0.12~0.16%, Mn：≤ 0.2%, Mg：≤ 0.02%, Zn：≤ 0.03%, Ti：≤ 0.03%,
Y：0.06~0.08%, each ＜ 0.05% of other impurities element, impurity element adds up to ＜ 0.15%, surplus Al.
Further, the novel antibacterial eats aluminium foil, and the mass percent of each ingredient is：Si：0.13%, Fe：
1.30%, Cu：0.14%, Mn：0.2%, Mg：0.02%, Zn：0.03%, Ti：0.03%, Y：0.07%, other impurities element
Each ＜ 0.05%, impurity element add up to ＜ 0.15%, surplus Al.
The advantageous effect that the present invention is compared with the prior art：
(1) from the test data of Examples 1 to 3, novel antibacterial provided by the invention eats aluminium foil not only to bacterium
There is excellent antibiotic property, also there is excellent antibiotic property to fungi.Wherein, to staphylococcus aureus, Escherichia coli and white
The antibiotic rate of candida albicans is more than 99.5%；
(2) by the data of embodiment 3 and comparative example 1~3 as it can be seen that addition Cu elements and Y element are in the anti-of 8079A aluminium alloys
Bacterium property plays synergistic effect in being modified, and aluminium foil is made to have excellent antibiotic property.This is because Y element has certain resist in itself
Bacterium ability can influence the content of important meals element in bacterial body, such as Ca elements, live so as to influence the normal physiological of bacterium
It is dynamic, its growth breeding is caused to be suppressed, it is last dead.Under the collective effect of Cu elements and Y element, the antibiotic property of aluminium foil obtains
To significantly increasing；
