Method for manufacturing a rubber magnet with a colored facial gum material layer and a rubber magnet thereof
A method for manufacturing a rubber magnet with a colored facial gum material layer and a rubber magnet thereof. A colored gum material layer is paved on a surface of the rubber magnet. A surfactant is added into the colored gum material layer. An identical surfactant or a surfactant with very close polarity is added into the material of the rubber magnet, whereby the surfaces of the gum material layer and the rubber magnet can tightly adhere to each other without easy peeling. In addition, antiscaling agent, wetting/spreading agent and defoaming agent are added into the gum material layer to fully wet the color and uniformly spread the color over the gum material so as to enhance the evenness of the color.
This application is a Divisional patent application of co-pending application Ser. No. 11/492,990, filed on 26 Jul. 2006. The entire disclosure of the prior application, Ser. No. 11/492,990, from which an oath or declaration is supplied, is considered a part of the disclosure of the accompanying Divisional application and is hereby incorporated by reference.
BACKGROUND OF THE INVENTIONThe present invention is related to a method for manufacturing a rubber magnet with a colored facial gum material layer and a rubber magnet thereof. By means of the method, the surfaces of the colored gum material layer and the rubber magnet can tightly adhere to each other without easy peeling. Moreover, the evenness of the color of the facial gum material layer is enhanced.
A conventional rubber magnet is made from a mixture of a rubber/plastic complex material and ferric oxide powder added into the rubber/plastic complex material. The mixture is at least once magnetized to become flexible rubber magnet having magnetic poles for attracting iron-made articles.
In use of the conventional rubber magnet, it often takes place that the ferric oxide powder drops down to contaminate a user's hands. The magnetic powder is toxic so that in the case that the user incautiously eats it or some sensitive parts (such as the eyes) of the user contact the toxic powder, the user's health will be greatly affected.
In order to overcome this problem, as shown in
On the other hand, due to the composition of ferric oxide, the color of the surface of the rubber magnet is black brown. In order to change the color of the surface of the rubber magnet, in a typical manner, the surface is printed or painted with a paint. However, the ferric oxide particle structure is quite different from the paint particle structure. Therefore, the paint can hardly adhere to the rubber magnet. It often takes place the paint at the folding section of the soft magnet such as paper clip, decorative sheet and bookmark peels off or cracks. This results in poor appearance of the magnet and pollution of environment.
It is therefore a primary object of the present invention to provide a method for manufacturing a rubber magnet with a colored facial gum material layer and a rubber magnet thereof. By means of the method, the surfaces of the colored gum material layer and the rubber magnet can be tightly bonded with each other without easy peeling.
According to the above object, the method for manufacturing a rubber magnet with a colored facial gum material layer of the present invention includes a step of paving a colored gum material layer on a surface of the rubber magnet. An anionic surfactant is added into the colored gum material layer. An identical surfactant or a surfactant with very close polarity is added into the material of the rubber magnet, whereby the surfaces of the gum material layer and the rubber magnet can tightly adhere to each other without easy peeling.
The present invention can be best understood through the following description and accompanying drawings wherein:
Please refer to
The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
