Method for manufacturing a rubber magnet with a colored facial gum material layer and a rubber magnet thereof

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.

1 . A colored rubber magnet made from a mixture of magnetizable materials, plastic/rubber complex material and nonionic surfactant, a colored gum material layer being paved on at least one surface of the rubber magnet, an anionic surfactant being added into a material of the gum material layer, the anionic surfactant having a polarity very close to that of the nonionic surfactant. 
   
   
       2 . The colored rubber magnet as claimed in  claim 1 , wherein the colored gum material layer is a mixture of substrate UV hardened resin and at least some of the additives of paint or color powder, antiscaling agent, wetting/spreading agent, defoaming agent and sealant. 
   
   
       3 . The colored rubber magnet as claimed in  claim 2 , wherein the antiscaling agent is an anionic surfactant or polyvinyl wax. 
   
   
       4 . The colored rubber magnet as claimed in  claim 2 , wherein the wetting/spreading agent is amine salt of polycarboxylic acid. 
   
   
       5 . The colored rubber magnet as claimed in  claim 2 , wherein the defoaming agent is non-silicone organic compound. 
   
   
       6 . The colored as claimed in  claim 2 , wherein the sealant is amino silane. 
   
   
       7 . The colored as claimed in  claim 1 , wherein the colored gum material layer is paved on one single surface of the rubber magnet sheet. 
   
   
       8 . The colored as claimed in  claim 2 , wherein the colored gum material layer is paved on one single surface of the rubber magnet sheet. 
   
   
       9 . The colored as claimed in  claim 3 , wherein the colored gum material layer is paved on one single surface of the rubber magnet sheet. 
   
   
       10 . The colored as claimed in  claim 4 , wherein the colored gum material layer is paved on one single surface of the rubber magnet sheet. 
   
   
       11 . The colored as claimed in  claim 5 , wherein the colored gum material layer is paved on one single surface of the rubber magnet sheet. 
   
   
       12 . The colored as claimed in  claim 6 , wherein the colored gum material layer is paved on one single surface of the rubber magnet sheet. 
   
   
       13 . The colored as claimed in  claim 1 , wherein two colored gum material layers are paved on both surfaces of the rubber magnet sheet. 
   
   
       14 . The colored as claimed in  claim 2 , wherein two colored gum material layers are paved on both surfaces of the rubber magnet sheet. 
   
   
       15 . The colored as claimed in  claim 3 , wherein two colored gum material layers are paved on both surfaces of the rubber magnet sheet. 
   
   
       16 . The colored as claimed in  claim 4 , wherein two colored gum material layers are paved on both surfaces of the rubber magnet sheet. 
   
   
       17 . The colored as claimed in  claim 5 , wherein two colored gum material layers are paved on both surfaces of the rubber magnet sheet. 
   
   
       18 . The colored as claimed in  claim 6 , wherein two colored gum material layers are paved on both surfaces of the rubber magnet sheet.
