Description

Magnet structures with colorable surfaces

Technical field:

The utility model relates to a magnet structure with a colorable surface, in particular to an inking surface layer covered with magnets and pigments on the surface of the magnet, both of which have high adhesion (high adhesion), so as to improve the coloring or coloring on the surface of the magnet. Printing pattern processing technology.

Background technique:

Generally, magnets are mostly made of iron oxide powder or added to a composite material mixed with rubber and plastic, and then undergo at least one magnetization process, so that the composite material will induce magnetic poles, and then form a flexible magnet that can adsorb ferrous materials. magnet.

Special attention should be paid to the fact that when the traditional rubber magnet is used, the magnetic powder (iron oxide) will fall off and stick to the hands of the user; Ingestion or contact with more sensitive parts of the body (such as eyes) will cause great harm to health.

In order to improve this problem, in the known technology, as shown in Figure 1 and Figure 2, a layer of varnish or coating material 61 will be coated or plate printed on the surface of the rubber magnet to isolate, but, due to the general rubber material Or the surface characteristics of the paint and the magnet are very different. Therefore, the paint layer at the folded part of the magnet still often cracks or peels off due to the operation in use, resulting in an unattractive surface of the soft magnet and easy contamination during use. Shortcomings.

On the other hand, the color of the surface of the known rubber magnet is dark brown due to the iron oxide component. If the color of the surface of the rubber magnet is to be changed, in a typical method, it is printed or printed with pigment or paint on the surface of the magnet. However, due to the particle structure of the rubber magnet (iron oxide), it is far from the material structure of the general paint material, so that the paint (paint) material is not easy to directly attach to the magnet; and, even if the pigment has been successfully attached to the The surface of the magnet, in the future use process, especially the color (paint) material on the surface of rubber magnet items such as soft magnet clips, binder clips, bending trims or magnetic bookmarks that are often bent and used , it will cause poor adhesion due to the great difference between the particles and the magnet, and it is easy to fall off or crack; when the user uses the magnet with poor adhesion effect of the surface isolation layer or color layer, the peeling off Magnetic powder or paint will cause obvious pollution problems, and when it is desired to make patterns on the surface, the color saturation is greatly limited, so only simple graphics can be achieved, and the scope of use cannot be expanded. Therefore, how to stabilize the coloring on the surface of the magnet, and how to increase the adhesion between the paint (paint) material and the magnet are issues that need to be broken through in the relevant industries.

Previously, it was proposed that on the surface of the rubber magnet 60, as shown in FIG. 3 , use glue or machine tool to process and paste paper, PP synthetic paper, PVC or PET surface layer 62 with color or pattern to form isolation and surface color. However, this type of magnet is still easy to cause surface wrinkles or surface peeling during use and affect the appearance, which cannot completely solve the problems of the traditional ones, and the pattern manufacturing of the surface layer 62 each time is limited by the plate fee of the printing machine. However, there is a requirement for a minimum print volume, and it is difficult to extend to a very small number of user groups with a print volume.

Furthermore, there is currently no magnet that can directly provide users with coloring, drawing or printing on its surface. Although some people have tried to pre-paste matching materials such as paper, synthetic surfaces or cloth on the surface of the magnet, and then The surface of the matching material is colored or printed to produce a more saturated and beautiful color effect, but it still cannot break through the above-mentioned lack of easy falling off or cracking and creases, which needs to be improved urgently.

Recently, some people use mixed paint (lacquer) to coat the surface of the magnet 60. Although it can improve the peeling or cracking of the color layer, it can no longer be easily colored or printed on it. See Figure 4.

Typically, if the structural structure of the magnet can be redesigned and considered, and an inked surface layer with good ink or pigment adhesion can be provided to improve the above-mentioned lack of easy coloring, it will provide a substantial growth in the application range of magnet products Effect.

Utility model content:

The technical problem to be solved by the utility model is to provide a magnet structure with a colorable surface in view of the deficiencies of the above-mentioned prior art, that is, to prefabricate a layer of ink-coated surface layer on the surface of the magnet with extremely high adhesion to the magnet, and the ink-coated surface layer It is close to the characteristics of the pigment (paint) material or ink, and can produce a tight and stable bonding effect between them, so that the surface of the magnet can present a special colorable color that is not easy to fall off due to the close bonding of the ink surface layer. Or printable properties, forming a structural layer that can beautify the surface of the magnet.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a magnet structure with a colorable surface, including a magnet, the surface of the magnet is arranged with an inked surface layer with a high degree of adhesion between the magnet, and the The inked surface layer also has high adhesion to ink or pigment.

The ink-receiving surface layer is a thin layer arranged by the ink-receiving layer material produced by mixing high molecular resin, good ink-absorbing raw material and adhesion promoter.

In this way, the above-mentioned inked surface layer is firmly bonded to the surface of the magnet and is not easy to peel off, and then it can be colored or printed on the inked surface layer, so that the effect of the coloring or printing of these magnets can be moderately improved, and the surface of the magnet is relatively expanded. Reliable range for printing; coating the non-colorable side of the thin magnet with an adhesive layer (coated with adhesive on the back of the magnet), so that at least one side has the effect of sticking other objects, which will be more convenient to use ; When the thin magnet with back glue is cut into long strips, it can become a tape-type magnet, which makes the application range wider; if there is an embossed structure arranged continuously in the same direction on at least one surface When the tearable grain structure such as linear pit structure and fine groove structure will be beneficial to the user to apply an external force or shear force to the magnet along the at least one continuously arranged tearable grain structure, it can be obtained from the The path arranged by the tearable grain structure is easy to tear or tear off; according to the above-mentioned magnets with backing adhesive and divided into long strips, they can be rolled into a wrapping state, that is, a tape form.
