Description
Technical field
The present invention relates to a kind of double property magnetic paper products directly printed.
Background technology
The paper such as decorating printing material, wallpaper, advertisement consumptive material and magnetic material are combined together into what can be directly printed
Magnetic paper product makes the putting up of paper using magnetic attraction, replaces magnetic material that is more convenient, but being combined in the prior art with paper
Expect permanent magnetism either soft magnetism, either only soft magnetic characteristic can only adsorb in permanent magnetism substrate or at it such magnetic paper
Continue to adsorb permanent magnet product on face, can not but adsorb in soft magnetism substrate or continue to adsorb soft magnetic products in the above；Or
Magnetic paper only has magnetic property, can only adsorb and permanent magnetism substrate or permanent magnetism object are either conditionally adsorbed in soft magnetism substrate, this
It must be that pairing is magnetized that absorption between kind permanent magnetism, which is limited by, it is necessary to be at complete pairing, at this time suction is just most strong, in suction most
Weak place can come off because not enough securely due to, and it is even more smoothly arbitrarily to move that the permanent magnet that magnetic paper adsorbs above is too big because suction fluctuates
Dynamic and rotation.
CN201037294Y discloses a kind of iron wallpaper, and which disclose the magnetic product for realizing arbitrary polarity is random
Ground is adsorbed on its surface, can easily be used without the polarity for strictly distinguishing magnetic product, thus structure is more reasonable, and
Also be not present because usage time relatively long and it is magnetic weaken, adsorption capacity declines so as to the situation for influencing to use, as long as ensureing magnetic
Product have enough magnetic force can normal use, be very beneficial for producing and apply；It can be by arbitrary carrying magnetic using the technology
Object arbitrarily absorption thereon, and can arbitrarily shift one's position and change moulding as needed, very easy to use, applicable model
It encloses relatively wide.There are being all the collocation of permanent magnetism soft magnetism between the object that problem is institute's magnetic in need, soft magnetism and soft magnetism inherently reality
Now not absorption, this iron wallpaper can not adsorb on soft magnetism basal surface and continue to adsorb iron glue product on its face.
The prior art is all to play its magnetic conduction as independent stratum and concentrate acting on for the magnetic line of force, magnetic layer by the soft magnetosphere of magnetic
And independent stratum plays its magnetic property.The height of magnetic property is all closely bound up with the content of permanent magnetism powder, and those skilled in the art are total
It is to be utilized with pursuing particle content high as possible to reach the maximum of magnetic property.Any addition for not reaching microcosmic spin-exchange-coupled
Magnetic domain spacing in magnet will be caused to widen, weaken whole maximum magnetic energy product (BH) max of magnet, the macroscopic view for reducing magnet is right
Outer magnetic property.The mixing without microcosmic spin-exchange-coupled that the professional of magnetic industry will not carry out soft magnetism permanent magnetism phase is tasted
Examination utilizes, because undisputable fact is confronted, without the mixing of the permanent magnetism, soft magnetism of microcosmic spin-exchange-coupled, can only reduce mixed
Fit magnetic property, can only increase magnet volume to make up in this way, this is opposite with real needs.Whenever encountering permanent magnetism soft magnetism
When being used in mixed way, mixture remanent magnetism, coercivity are improved, the magnetic property of maximum magnetic energy product becomes the pursuit of those skilled in the art, phase
It is all pursuit to magnet magnetic property after mixing to close patent, using be all by the way of sintering etc. can realize microcosmic spin-exchange-coupled,
For example patent disclosed in correlation：CN104529424A, a kind of composite permanet magnet that there is two-phase spin-exchange-coupled and keep high-coercive force
Ferrite；CN104332262A, a kind of high energy product nanometer two-phase composite permanent-magnetic material and preparation method thereof；
CN103730227A, a kind of nano biphase isotropic composite permanent magnet and preparation method thereof.
Existing patent also relates to the patent that permanent magnetism and soft magnetism are used in mixed way, for example, CN201400829Y disclose one kind can
The magnetic paper product directly printed, including the printing layer that can be directly printed, the printing layer is provided with magnetic coating layer on one side,
The magnetic coating layer tight union is in the surface of printing layer.Its advantageous effects is：(1) the magnetic paper product thickness is thin, single
The thickness of the magnetic paper product of layer paper structure is most thin to can reach 0.1mm, and existing magnetic glue technology is difficult to realize such effect, because
This magnetic paper product has wider array of application range than existing product, and industry neck can also be applied to by being applicable not only to office realm
Domain；(2) the magnetic paper product flexibility is good, substantially suitable with paper used, also more convenient using more saving space；(3)
Since the making of magnetic coating is easy compared with the production of magnetic glue, thus the production technology of the magnetic paper product is more simple, and production cost is more
It is low；(4) the magnetic paper product directly can be printed in the printing layer of its one or both sides, be printed, be write and be beautified outside it
It sees；Using more convenient；(5) since the product relative weight is lighter, it is thus possible to larger magnetic force is obtained, it can be more secured
Ground is adsorbed in irony or the tool face of magnetic substance, plays beautifying and decorating effect.It can be seen that the patent is also thinner more to pursue merely
Small volume and the suction of bigger securely for the purpose of absorption, are not related to the technique effect of double property magnetic, because according to this specially
The technique effect that the mixed zone of the permanent magnetism soft magnetism of profit is come must be the decline of magnet magnetic property, and the thing followed is magnet body certainly
To enhance magnetic property, this runs in the opposite direction with the purpose of patent for long-pending increase.
