Patent Application

The present invention is related to a magnetizable painting which is manufactured at lower cost and can be easily processed and magnetized.
A conventional magnet is made of iron or metal substrate material containing magnetic compositions, such as barium, strontium, rubidium, cobalt and boron. The substrate material is magnetized to have magnetic attraction. Such metal substrate material is rigid, inflexible and heavy. Also, it is hard to process and carry the metal substrate material. Therefore, the use of such metal substrate material is quite limited.
A soft magnet has been developed recently. Ferric oxide powder is added into a complex material which is a mixture of rubber and plastic. The material is at least once magnetized (magnetically aligned). Pulse current passes through a magnetic conductive disc with different magnetized divisions to induce different magnetic poles on the surface of the complex material. Accordingly, a flexible and soft magnet is formed. Such soft magnets can attract each other or attract an iron-made object. The soft magnet made from the rubber and plastic as the base material is flexible and light and is easy to process. Therefore, such soft magnet is widely used. However, in the manufacturing procedure, it is troublesome and complicated to add the ferric oxide powder into the rubber and plastic base material to form the soft magnet. Moreover, when adding the ferric oxide powder into the rubber and plastic base material, the flexibility and strength of the rubber and plastic material will be affected. As a result, the soft magnet tends to break and damage. Also, it is hard to thin such magnet so that the cost is increased.
In addition, the conventional technique for coloring the magnet is still not mature. As a result, in use, it often takes place that the color is detached from the magnet. Therefore, most of the magnets are black. It is therefore tried by the applicant to provide a better measure for coloring the magnet to beautify the appearance thereof.
It is therefore a primary object of the present invention to provide a magnetizable painting containing a base painting, a certain amount of magnetizable material added to the base painting and a certain amount of spreading processing aid added to the base painting. The mixture is fully stirred to evenly distribute the magnetizable material in the base painting to form the magnetizable painting. The magnetizable painting can be coated on the surface of various substrate materials to form a magnetizable coating. The coating is at least once magnetized to make the magnetizable material in the magnetizable painting become magnetic material, whereby the surface of the substrate material has the same property as a magnet. By means of the magnetizable painting, it is easier to magnetize the surface of an object. In addition, the magnetizable coating on the surface of the substrate material can be fully thinned to reduce cost. Also, the original strength of the substrate material will not be affected so that it is uneasy to damage the magnetic material.
It is a further object of the present invention to provide the above magnetizable painting in which the spreading processing aid can be a composition of gluing agent, anti-sediment agent, wetting agent, defoamer agent and color spreading agent for enhancing the evenness of the mixture of the magnetizable material. After the magnetizable painting is sprayed onto the surface of the object and magnetized, the magnetizable painting can have evener and more stable magnetic properties.
In the case that a color is directly added to the magnetizable painting, in manufacturing, the magnet can be colored as necessary to beautify the appearance.
The present invention can be best understood through the following description and accompanying drawings wherein:
Please refer to
The magnetizable painting 21 can be sprayed onto the surface of the substrate material 5 with different thickness and evenness according to the pattern of the substrate material 5 and the required color. The magnetizable painting 21 can be painted on the substrate material 5 with a brush, roller, sprayer, halftone printing or scraper.
In addition, when blending the painting, a desired color 10 can be selectively added into the painting to achieve various colors of magnetizable paintings 21. Therefore, the application range of the magnetizable paintings 21 can be widened and more convenient.
By means of the magnetizable painting of the present invention, it is easier to magnetize the surface of an object without limitation of the aspect of the surface. The magnetizable coating 22 on the surface of the substrate material 5 can be fully thinned. The color is directly blended with the painting to color the painting so that the second coloring processing is unnecessary. Also, the shortcoming of detachment of the color is eliminated. Therefore, the utility of the magnet is greatly enhanced and the cost is reduced. In addition, it is easier to process and magnetize the object.
The above embodiment is only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiment can be made without departing from the spirit of the present invention.
This application is a divisional of U.S. Ser. No. 11/068,819 entitled “Magnetizable Painting” filed on Mar. 2, 2005 and currently pending.
