Invention Title: COLORING STRUCTURE OF SOFT MAGNET The following statement is a full description of this invention, including the best method of performing it known to me/us: COLORING STRUCTURE OF SOFT MAGNET Field of the Invention The present invention relates to a kind of coloring structure for a soft magnet.
Backtround of the Invention Generally, soft magnets are fabricated by magnetizing the composite material of rubber and plastic added with powders of iron oxide at least one time, and using the permeability disc, which has pulse current passing through itself and includes divided magnetic zones, to make the surface of the base material induce different magnetic poles. Thereby, flexible soft magnets that attract to each other or to iron substances (attracted articles) are formed. Such soft magnets may be applied to the fabrication of bookmarks or the positioning of documents.
The magnetic powders (iron oxide) of traditional soft magnets in use flake off and adhere to hands of users easily. Unfortunately, the magnetic powders are poisonous. If users do not clean up the residual magnetic powders on their hands timely after making use of the magnets, the residual magnetic powders may be swallowed or contacted with somewhere sensitive eyes), damaging health accordingly.
To solve the aforesaid problem, a layer of lacquer is coated onto the surface of the soft magnet in the prior art. However, some magnetic powders still flake from the folds of soft magnets due to the occurrence of cracks in operation. In addition, the layer of lacquer is often contaminated or stained with dust or fingerprints when being used. It is harmful to the appearance of the soft magnet.
On the other hand, the surface of the soft magnet presents black/brown owing to the existence of iron oxide. A typical method of changing the surface color of the soft magnet is to print or coat pigment or paint on the surface of the soft magnet.
The particle size of the magnetic powders (iron oxide) is far smaller than that of paint or pigment, so the magnetic powders or paint is poorly adhered to the soft magnet.
As soft magnets are applied especially to foldable soft magnetic clips, files, bended decorations, or magnetic bookmarks, the colored surface of the soft magnet tends to fracture, and paint or magnetic powders peel off easily because of the poor adhesion resulting from the great difference in particle sizes between paint on the surface of the soft magnet and magnetic powders.
Moreover, the magnetic powders or paint flaking from the soft magnet with poor adhesion smears hands as well. The issues on coloring the surface of soft magnets and enhancing the adhesion between paint and soft magnets are troublous and need some solutions.
Representatively speaking, the composition or structure of soft magnets may be modified to overcome the aforementioned disadvantages.
Summary of the Invention Accordingly, it is a primary object of the invention to provide a coloring structure for a soft magnet, which comprises a paint layer with particular materials and pigment coated onto a surface of a soft magnet, and a layer of crystallite adhesive formed after irradiating the paint layer by ultraviolet rays, of which particle size is approximate to that of the magnetic powders of the soft magnet. The crystallite adhesive layer and the soft magnet constitute a compact crystalline structure.
Because the surface of the soft magnet is combined tightly with the adhesive layer, the surface thereof presents a particularly color-distributed texture and the soft magnet looks better.
Substantially, the invention comprises a soft magnet including a magnetic layer at its base, and a paint layer disposed over the top of the magnetic layer. After the paint layer is irradiated with ultraviolet rays, a layer of crystallite adhesive is formed on the surface so that a crystalline structure is formed between the crystallite adhesive layer and the magnetic powders of the soft magnet. Hence, a wear-proof soft magnet, in which paint has no tendency to flake or crack, is obtained.
The foregoing aspects, as well as many of the attendant advantages and features of this invention will become more apparent by reference to the following detailed description, when taken in conjunction with the accompanying drawings.
Brief Description of the Drawings Fig. 1 is a diagram showing the mixing of paint and particular materials according to an embodiment of the invention.
Fig. 2 is a diagram showing that a mixture including paint is coated onto a soft magnet by a coating device according to an embodiment of the invention.
Fig. 3 is a diagram showing that a coated magnet is irradiated by ultraviolet rays according to an embodiment of the invention.
Fig. 4 shows the structure that combines a crystallite adhesive layer and a soft magnet according to an embodiment of the invention.
Detailed Description of Some Embodiments Referring to Fig. 1 through Fig. 3, the coloring structure in accordance with one embodiment of the invention is manufactured by the following steps.
In step 1, multi-functional nitro acrylic acid 11, acrylic resin 12, an organic solvent 13, pigment 14, and an additive 15, such as glitter powders, are mixed by a mixing device to be a paint, which may be a kind of UV paint as shown in Fig. 1.
In step 2, the mixture of paint is coated onto a soft magnet 3 composed of a magnetic layer by an applicable coating device, so as to form a layer of paint 1 with a predetermined thickness of about 0.01 millimeters (mm) as illustrated in Fig. 2.
In step 3, the layer of paint 1 is exposed to the irradiation of ultraviolet rays 51 out of an ultraviolet source 5 for a certain period of time until the layer of paint 1 forms a layer of crystallite adhesive 31 as shown in Fig. 3 and Fig. 4; wherein the crystallite adhesive layer 31 reacts with the surface of the soft magnet 3 to form a crystalline structure 32, i.e. the crystallite adhesive layer 31 and the crystalline magnetic layer of the soft magnet 3 are inlaid mutually and compactly. As a result, the layer of paint 1 constitutes a protective layer that is smooth and wear-proof, and can avoid flakes or cracks.
According to another embodiment of the invention, a lubricant (not shown) may be added in the step 1 of mixing. As such, after the layer of paint 1 is coated onto the soft magnet 3, the isolation of crystallites is built. It is thus difficult for other impurities to permeate through the layer of paint 1 and combines with each other.
According to yet another embodiment of the invention, an additive 15 (e.g.
glitter powders) is added into the pigment 14 in the step 1. Consequently, some specific visual effects like bright spots or foggy textures are produced on the layer of paint 1 deployed over the soft magnet 3.
Referring to Fig. 4, which comprises a soft magnet 3, the soft magnet 3 is composed of a magnetic layer disposed at its bottom, and a layer of paint 1 is deployed over at least a surface of the soft magnet 3. A layer of crystallite adhesive 31 is formed on the surface of the paint layer 1 by processing the layer of paint 1, 4 such as mixing, coating and irradiating with ultraviolet light. A crystalline structure 32 is further formed between the crystallite adhesive layer 31 and the magnetic layer C of the soft magnet 3. Because the crystalline structure 32 is embedded in the magnetic layer compactly, the soft magnet 3 becomes wear-proof, the paint thereon
;Z
has no tendency to fall off or crack, and the surface thereof is not stained with dust, Sfingerprints or other contamination.
Meanwhile, the pigment 14 is distributed among the crystallite adhesive layer 31 Sto form a coloring structure as illustrated in Fig. 4 so that the pigment 14 is bonded 0 with the soft magnet 3 more stable. Furthermore, the soft magnet 3 may include various and particular deployments of color that does not flake off easily in use.
STherefore, the soft magnet is superior to and more beautiful than a convention Smagnet.
In summary, the method of coloring a soft magnet in the invention and the product made thereby have solved the problems in prior arts. That also advances the techniques in the field of magnets and meets the requirements of patentability.
While the invention has been particularly shown and described with reference to the preferred embodiments thereof, these are, of course, merely examples to help clarify the invention and are not intended to limit the invention. It will be understood by those skilled in the art that various changes, modifications, and alterations in form and details may be made therein without departing from the spirit and scope of the invention, as set forth in the following claims.
