Detailed description of the invention
Fig. 1 is the structural schematic diagram of magnetic coupling plate.
Wherein, 1- facestock layer；2- magnetosphere；3- substrate layer.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
The utility model embodiment is related to a kind of magnetic coupling plate.As shown in Figure 1, the magnetic coupling plate includes setting gradually
Facestock layer 1, magnetosphere 2 and substrate layer 3, magnetosphere 2 contains binder and magnetisable material, for by facestock layer 1 and substrate
Layer 3 is bonded.Compared with prior art, the utility model without being prepared magnetosphere 2 in advance, and uses magnetic viscose glue will
Facestock layer 1 and substrate layer 3 are bonded, and the mode of magnetosphere 2 is obtained after solidification, it is possible to reduce manufacturing process, and can obtain
The magnetic bulletin board of arbitrary dimension.
In one embodiment of the utility model, for convenient for pricking nail, facestock layer 1 is with elastic and softer quality plate
Shape body.Its material can be selected from least one of cork, flannelette, felt, non-woven fabrics, woven cloth, EVA.
When due to using H-shaped nail, rivet nut need to sequentially pass through facestock layer 1, magnetosphere 2 and substrate layer 3.Therefore with facestock layer 1
Similar, substrate layer 3 should also select the plate body with appropriate intensity.In order to avoid saturating by I-shaped pinning, damage metope, Ke Yi
The compound upper one layer of hardboard in the substrate layer back side, such as galvanized sheet.The material of substrate layer 3 can be selected from low density fiberboard (such as bagasse board, it is soft
Matter fiberboard etc.), cystosepiment, cardboard, EVA, polyester fiber, at least one of felt.Due to the higher cost of cork, and base
The thickness of material layer 3 is greater than facestock layer 1, therefore cork is not used in substrate layer 3.
It is of course also possible to the substrate layer 3 for selecting H-shaped nail that can not penetrate, such as select medium-density plate as substrate layer 3
Material.The magnetic coupling plate can only adsorb magnetic nail at this time, not be available H-shaped nail.
In the utility model, the binder that binder can be used plate field common, such as ethyl acetate (white glue with vinyl), third
At least one of olefin(e) acid, amylan, epoxy resin, polyurethane, polyvinyl alcohol, protein adhesive, EVA glue, with realize facestock layer 1 with
The bonding of substrate layer 3.
Be added in magnetosphere 2 magnetisable material purpose be with the magnetic material effects such as magnetic nail, to laminar article into
Row is adsorbed and is fixed.In one embodiment of the utility model, magnetisable material is selected from simple substance or the oxidation of Fe, Co, Ni, Gd
The alloy of object and above-mentioned element.
In one embodiment of the utility model, magnetisable material can also be ferrite permanent-magnet materials or rare earth permanent magnet
Material.Both material prices are relatively high, have permanent magnetism after magnetizing.Price is more than ten times even tens times of iron powder.Wherein,
Composite oxides (such as BaO6Fe of the oxide of iron and one or more of other metal oxide compositions2O3、MnO·
Fe2O3·ZnO·Fe2O3Deng) etc. be known as ferrite.The most common are neodymium iron boron Nd for rare earth permanent-magnetic material2Fe14B.Neodymium iron boron is
Tetragonal crystal is most common permanent magnet.In the present invention due to cost considerations, it is preferable to use iron powder or four
The powder of Fe 3 O is as magnetisable material.
In one embodiment of the utility model, in order to make magnetosphere 2 preferably play a role, by the thickness of facestock layer 1
Degree is set as 0.3~2mm, substrate layer 3 with a thickness of 5~10mm, magnetic coupling plate with a thickness of 6~15mm.As facestock layer 1 is thick
It spends big, it is not easy to realize magnetic nail in the absorption of composite surface.
In one embodiment of the utility model, in magnetosphere 2, the volumn concentration of magnetisable material is 30%~
80%.Applicants have found that under conditions of using general-purpose adhesive, it, should be as far as possible for the magnetic suck for improving composite plate
Magnetisable material mostly is added.But if the volumn concentration of magnetisable material is higher than 90%, magnetisable material and binder
The binding force of the magnetic viscose glue obtained after mixing declines, and cannot achieve combining closely for substrate layer 1 and facestock layer 3.
The production method that the utility model further relates to magnetic coupling plate, method includes the following steps:
(1) it is sufficiently mixed magnetisable material with binder, obtains magnetic viscose glue.Further, which can be by normal
The dispersion instrument of rule realizes that the machinery includes rubber roller, dispersion machine and blender etc..Or it is mixed in a manner of manually stirring
It closes.
(2) magnetic viscose glue is coated on 3 surface of substrate layer, is then pressed with facestock layer 1, after magnetism viscose glue solidification
Form magnetosphere 2.Further, the coating process is any in the modes such as hairbrush coating, plastic roll, gluing, frictioning, glue spraying
It is a kind of.Magnetic viscose glue can also be coated on to 1 surface of facestock layer, then pressed with substrate layer 3.
The utility model further relates to a kind of magnetic bulletin board, which includes frame and magnetic coupling above-mentioned
Plate, frame are located at the composite plate surrounding.The material of frame can be wooden, MDF, plastics or metal.It can also use soft
Ornament materials be bulletin board bound edge.
Wherein, the meaning of MDF is medium density fibre board (MDF) (medium density fiberboard), is with plant fiber
For raw material, apply Lauxite or other synthetic resin, in the case where heat pressurized conditions density made of compacting 0.50~
0.88g/cm3Other suitable additives can also be added to improve sheet properties in the plate of range.
The magnetic coupling plate can be also used for production furniture panel or the panel of other office appliances, have both practical and beautiful
The performance of sight.
Examples 1 to 5
A kind of magnetic coupling plate, including facestock layer 1, magnetosphere 2 and the substrate layer 3 set gradually.The material and group of each layer
At being shown in Table 1:
Table 1
Using the H-shaped nail for following closely a length of 8mm, and common commercially available strong magnetic nail (its magnetic material is neodymium iron boron), it is by weight
The postcard of 5g is fixed on the magnetic coupling plate surface that Examples 1 to 5 is prepared.H-shaped nail penetrates the complexity of composite plate
2 are shown in Table with the fixation degree of magnetic nail.
Table 2
From table 2 it can be seen that can be realized the magnetic coupling plate of Examples 1 to 3 using H-shaped nail and magnetic nail pair
The fixation of postcard.Facestock layer is such as replaced with into the higher medium-density plate of hardness, or reduces magnetisable material in magnetosphere
Content or spread, the fixed performance of magnetic coupling plate can be declined.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
