ABSTRACT:
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.
