Background

The conventional bulletin board requires the use of a letter nail for fixing a picture or paper, and has the following disadvantages: 1. the surface of the bulletin board is damaged by frequent nail pricking, so that the service life of the bulletin board is shortened; 2. the nail binding causes nail holes on used sheet-like objects such as photos and paper; and 3, the use of the I-shaped nail by children is unsafe.

If no thumbtack is used, a magnetic billboard can be used. The existing partial magnetic bulletin board adsorbs the magnetic nail by using a magnetic or iron soft film, but still has the following defects: 1. the soft film needs to be formed and rolled, the manufacturing process is complex, and the cost is higher; 2. the bonding of the upper layer and the lower layer of the soft film and the bulletin board needs to be performed on two sides, and the process is complicated. 3. Because the magnetic soft film or the magnetizable soft film is limited by the size, the bulletin board is also limited by the size, the large size needs the jointed board, the process is more complicated, and the product quality is also reduced due to the jointed board.

In addition, the common magnetic bulletin board is formed by compounding a magnetizable sheet, a decorative surface material and a base plate capable of being nailed together by two layers of glue and then installing a frame. The magnetic force is general and cannot adsorb soft magnet.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The embodiment of the utility model provides a but magnetism is pricked and is nailed bulletin board is related to. As shown in fig. 1 and 2, the magnetic bulletin board includes a surface material layer 1, a wire layer 2, and a base material layer 3, which are sequentially disposed, and the surface material layer 1, the wire layer 2, and the base material layer 3 are bonded by an adhesive. The iron wire mesh layer 2 can contain one or more layers of iron wire meshes, can provide magnetism for adsorbing the magnetic nail, can provide a gap, and can be inserted into an I-shaped nail for fixing an object. Compared with the prior art, the utility model discloses need not to prepare in advance and obtain the magnetic layer, also need not to mix magnetic material and binder in advance and prepare the magnetic layer, can reduce manufacturing process to can obtain the magnetism of arbitrary size and can prick nail bulletin board. Meanwhile, the middle wire mesh layer can increase the overall compressive strength of the plate, so that cracks can not occur during use, and the bulletin board is more durable.

In one embodiment of the present invention, the face material layer 1 is a plate-like body with elasticity and soft texture for facilitating the binding. The material can be selected from at least one of cork, flannelette, felt, non-woven fabric, woven fabric and EVA.

When the I-shaped nail is used, the nail body needs to sequentially penetrate through the surface material layer 1, the iron wire mesh layer 2 and the base material layer 3. Therefore, similar to the surface material layer 1, the substrate layer 3 should also be a plate-shaped body with appropriate strength to avoid being pinned through by an i-shaped pin and damaging the wall surface. The material of the substrate layer 3 can be at least one selected from low-density board, foam board, EVA, polyester fiber, felt, paperboard, honeycomb board, KT board and composite board. Because the cost of cork is higher, and the thickness of substrate layer 3 is greater than surface material layer 1, therefore not use cork in substrate layer 3.

The utility model discloses in, the binder can use the common binder in panel field, for example, at least one of ethyl acetate, acrylic acid, starch glue, epoxy, polyurethane, polyvinyl alcohol, albumen glue, EVA glue to realize the bonding of surface material layer 1 and substrate layer 3.

The iron wire mesh layer 2 is added between the surface material layer 1 and the base material layer 3 to act with magnetic substances such as magnetic nails and the like to adsorb and fix sheet-shaped articles. In one embodiment of the present invention, the wire netting is a wire netting with a surface coating, which is used to prevent rusting around the production of the bulletin board, and to reduce the bonding firmness and product firmness. The wire is preferably a zinc-plated wire, a nickel-plated wire or a chrome-plated wire. The diameter of the iron wire is 0.15-0.4 mm, and the mesh number is 6-20 meshes. If the mesh number of the wire net is too low or the wire is too thin, the wire net per unit area is reduced in magnetism, and the magnetic nail can be attracted, but the magnetic soft white board cannot be attracted. Meanwhile, the mechanical strength of the wire mesh is too low, and the wire mesh is easy to damage during assembly and nail pricking. If the mesh number of the wire netting is too high, the material cost of the bulletin board is increased, and the insertion difficulty of the processed character nails is increased; if the wire diameter of the wire netting is too large, the surface material layer is easy to have indentation, and the bonding strength is reduced.

In addition, since the iron wire mesh layer 2 has a mesh structure, the binder can bond the surface material layer 1 and the base material layer 3 through the mesh. Therefore, three layers of materials can be bonded by one-time gluing. Compare the prior art that bonds with the magnetic layer respectively with surface material layer and substrate layer, the utility model discloses a bulletin board production simple process, low cost.

If the thickness of the surface material layer 1 is too large, the magnetic nail is not easy to be adsorbed on the surface of the bulletin board.

The utility model discloses still relate to the manufacturing method of this magnetism can prick nail bulletin board, this method includes following step: the adhesive is attached to the surface of the substrate layer 3 through modes of brush coating, glue rolling, gluing, glue scraping, glue spraying, screen printing and the like, then the iron wire mesh layer 2 and the surface material layer 1 are sequentially placed on the surface of the substrate layer 3 coated with the adhesive, and then pressing is carried out. Or the adhesive can be attached to the surface of the surface material layer 1, and then the wire mesh layer 2 and the base material layer 3 are sequentially placed on the surface of the surface material layer 1 coated with the adhesive and then pressed.

Further, the utility model discloses a bulletin board can be pricked to magnetism still includes the frame, and the frame is located bulletin board all around. The material of the frame can be wood, MDF, plastic or metal. The soft decorative material can also be used for edge wrapping of the bulletin board, and the bulletin board can be formed by additionally arranging a frame or a corner. Wherein MDF is medium density fiberboard (medium density fiberboard) prepared by applying urea-formaldehyde resin or other synthetic resin to plant fiber as raw material, and pressing under heating and pressurizing condition to obtain medium density fiberboard with density of 0.50-0.88 g/cm³Other suitable additives may also be added to the board of the range to improve board properties.

The magnetic bulletin board can also be used for manufacturing furniture panels or panels of other office supplies, and has practical and attractive performance. Can adsorb weak magnets such as neodymium iron boron strong magnet, ferrite common magnet, rubber magnet and the like, such as refrigerator sticker or magnetic soft white board and the like. If a small-sized magnetic soft white board is adsorbed on the surface of the surface material layer 1 of the bulletin board, a combined board which can be written, has magnetism and can be nailed can be obtained. Therefore, the embodiment of the present invention further provides a composite board, which includes the above-mentioned bulletin board, and a magnetic soft white board partially or completely adsorbed on the surface of the surface material layer 1 of the bulletin board.

Examples 1 to 5

A magnetic bulletin board comprises a surface material layer 1, an iron wire mesh layer 2 and a base material layer 3 which are sequentially arranged. The materials and compositions of the layers are shown in table 1:

TABLE 1

An I-shaped nail having nail lengths of 8mm and 11mm and a common commercially available magnetic nail were used to fix a postcard having a weight of 5g to the surface of the magnetic poster board prepared in examples 1 to 5. The ease of insertion of the i-pins into the billboard and the degree of retention of the magnetic pins are shown in table 2.

TABLE 2

As can be seen from table 2, the magnetic poster boards of examples 1 to 5 can be fixed to the postcard using the lettering and magnetic nails. However, if the pore size of the iron mesh layer is reduced, the fixing performance of the magnetic bulletin board is reduced, which shows that the magnetic nail can be attracted, but the magnetic soft white board cannot be attracted, as shown in example 2. Also for the 0.5mm diameter wire mesh of example 3, there would be an indentation if the face material was cork. If the facestock layer is replaced with a felt having a thickness of 2mm, there are no indentations. In example 5, when the mesh number is increased to 25 meshes, the I-shaped nails are not easy to prick.
