CN101455471A - Anti-magnetic shaping slice for leather goods - Google Patents

Abstract

The invention relates to a shaped sheet used by leather products, in particular to an antimagnetic shaped sheet used by leather products for preventing the bank card, credit card and other information magnetic cards from demagnetizing. The antimagnetic shaped sheet is made by soft magnetic material; the soft magnetic material and the nonferromagnetic metallic material film are made in one. Two antimagnetic shaped sheets replace the traditional shaped scrip, which not only solves the problem that the scrip shaping is easy to break and damp and deform, also solves the protection of preventing the bank card from demagnetizing by the leather products. The leather products with the antimagnetic shaped sheet use the magnetic shade action to prevent the bank card and other information magnetic cards from demagnetizing.

Description

The antimagnetic shaping slice of a kind of leatherware

Technical field

The present invention relates to the shaping slice that a kind of leatherware uses, particularly a kind of leatherware uses prevents bank card, the antimagnetic shaping slice of memory card and various information memory card demagnetizations.

Background technology

Little leatherwares such as wallet handbag are indispensable daily necessities in people's daily life now, and market demand is very big always.Simultaneously China and even all in the world business banks bank card that the savings client is provided all has one " magnetic stripe " and writes down savings content full detail.Extraneous static and Electromagnetic Interference all can make this magnetic stripe former orderlyly is interfered and destroys, thereby makes the magnetic stripe drop-out, and bank card or deposit card were lost efficacy.Magnet button on the various leatherwares still is many as the strong killer existence socially of magnetic card.And the leatherware of producing does not in the market substantially have the function of information storage card demagnetizations such as preventing bank card, mess card, medical card.Bring many inconveniences to daily life.The such situation of magnetic card demagnetization often has generation in each commercial silver provisional capital of China, and for example in the service area of Construction Bank Beijing branch, changed the quantity of card on average about 40 because of card loses efficacy every day.By this calculating, will be 10000 more than thousand over a year! What this brought to bank also is no small extra work.The client changes card and must pay, and discarded card also is a kind of waste from the angle of resource.Therefore say that the magnetic card inefficacy is weighed from any angle all has fraud not have profit.Leatherware production continues traditional processing technology always, and what the leatherware shaping material adopted always all is hardboard.The tradition leatherware has not folding, the shortcomings such as the back is yielding, the easy demagnetization of information storage card of making moist.

Summary of the invention

The invention provides and a kind ofly produce that leatherware uses, solved the anti-demagnetization of bank card, be more conducive to the antimagnetic shaping slice of leatherware typing.

For addressing the above problem, technology solution of the present invention is:

Replace traditional typing scraps of paper with two antimagnetic shaping slices, so promptly solved the problem that scraps of paper typing fractures easily, moisture-sensitive is out of shape, equally also solved leatherware to the demagnetization-protected protection of bank card.

Solve the problems such as the anti-tampering anti-magnetic field of antistatic of antimagnetic shaping slice, technology solution of the present invention is:

The high diamagnetic bank card of substantially all right and wrong that banks of China adopts, under the magnetic field intensity of 0.00034 to 0.00040 oersted, magnetic stripe will be damaged.The antimagnetic shaping slice that the present invention uses is that ferrimagnet is made, and can be used as the screen layer of armoured magnetic field, electrostatic field, electromagnetic interference.Just can reach effect with ferrimagnet as screen layer to magnetic screens such as bank card and information recording cards.Ferrimagnet is iron, cobalt, nickel and alloy thereof, also can be as ferritic electrolyte and terres rares.Product as this patent must not be selected hard magnetic material for use, and after will selecting for use soft magnetic materials (for example iron, silicon steel, permalloy) and this material by the external magnetic field magnetization, when external magnetic field was removed, the magnetic of this material can not keep.If make anti-magnetic card screen layer with hard magnetic material; under magnetic field, protected the magnetic card in the screen layer not to be subjected to the injury of external magnetic field; and after removing external magnetic field because the hysteresis effect of hard magnetic material makes and produces remanent magnetism in the screen layer, this remanent magnetism can cause certain infringement to magnetic card.The permeability height of desirable magnetic shielding material, as comprise the iron-nickel alloy (and high nickel steel) of permalloy (nickeliferous 36% to 81%).For example nickeliferous 49% to 51% iron-nickel alloy cold-strip product (below the thickness 1mm, model 1j50 and 1j51) just is suitable for making this patent product.Cheap soft magnetic materials is a ferritic steel.

Description of drawings

Fig. 1 is a structural representation of the present invention: wherein 1 is antimagnetic shaping slice, and 2 is the antimagnetic shaping slice placement location of wallet.

The specific embodiment

Make antimagnetic shaping slice with soft magnetic materials (for example ferritic steel sheet material, the iron-nickel alloy cold-strip of model 1j50,1j51 etc.).Soft magnetic materials (for example nickel, iron) and non-ferromagnetic metal material (for example aluminium) film are made one (nickel, iron can be covered on the aluminium film with technologies such as brush plating, plating, plasma sprayings), compound polyester film and the polyethylene film gone up in its both sides also can reach certain anti-magnetic field, antistatic, anti-electromagnetic radiation function then.Adopt plasma spraying can make the ratio of nickel and iron proper, can obtain to be similar to the permeability effect of permalloy.More than the thickness of various films all in micron.Adopt the antimagnetic effect of the composite membrane of electroplating gained to can not show a candle to ferromagnetic thin film, because iron-nickel alloy is more much bigger than single iron (0.676) or monomer nickel to absorption of electromagnetic wave loss value (3.54).But the effect of the anti-electromagnetic radiation of electroplating film is much better.The size of antimagnetic shaping slice is as the criterion with the leatherware size of using.

Consult Fig. 1, antimagnetic shaping slice 1 is placed in the inclusion of wallet (position 2 of antimagnetic shaping slice), replaces traditional hardboard to play the effect of wallet typing.

Claims (4)

1, the antimagnetic shaping slice of a kind of leatherware is characterized in that: described a kind of leatherware is made of soft magnetic materials of antimagnetic shaping slice.

2, as described in the right 1, it is characterized in that: soft magnetic materials and non-ferromagnetic metal material membrane are made one.
