Abstract

A method of manufacturing a resin molded article includes a step of preparing a resin powder having low dust generation property by adding a liquid paraffin to a thermosetting resin, and a step of obtaining a resin molded article by heating and kneading the resin powder having low dust generation property, in which the step of preparing the resin powder having low dust generation property includes a step in which the thermosetting resin is melted and the liquid paraffin is added to the melted thermosetting resin to be stirred and mixed.

1 . A resin powder having low dust generation property comprising:
 a thermosetting resin; and   a liquid paraffin,   wherein the average particle diameter is equal to or more than 1 μm and equal to or less than 100 μm.   
     
     
         2 . The resin powder having low dust generation property according to  claim 1 ,
 wherein the thermosetting resin includes a phenol resin or an epoxy resin.   
     
     
         3 . The resin powder having low dust generation property according to  claim 1 ,
 wherein the liquid paraffin includes a cycloparaffin.   
     
     
         4 . The resin powder having low dust generation property according to  claim 1  comprising:
 equal to or more than 0.05% by weight and equal to or less than 2% by weight of the liquid paraffin with respect to the total weight of the thermosetting resin.
