Abrasive material having an antiloading coating

Abstract

To determine what fine structure of the surface on which antiloading agents are applied performs the function of antiloading agents sufficiently. An abrasive material having an antiloading coating on an outermost surface thereof, in which the antiloading coating contains an antiloading agent and a binding resin, the binding resin is formed into a film with cracks, and a reticulate fine structure is formed on an entire surface of the antiloading coating by the cracks.

1 . An abrasive material having an antiloading coating on an outermost surface thereof, wherein 
 the antiloading coating contains an antiloading agent and a binding resin;    the binding resin is formed into a film with cracks; and    a reticulate fine structure is formed on an entire surface of the antiloading coating by the cracks.    
   
   
       2 . An abrasive material according to  claim 1 , wherein a longest diameter of a largest one among reticulations of said fine structure is 1000 μm or less.  
   
   
       3 . An abrasive material according to  claim 1 , wherein said binding resin has a glass transition temperature of 35° C. or more.  
   
   
       4 . An abrasive material according to  claim 1 , wherein said binding resin is formed into a film by drying particulate resin.  
   
   
       5 . An abrasive material according to  claim 4 , wherein said particulate resin is an aqueous latex or an aqueous resin emulsion.
