Resin pellet and method for producing the same

Abstract

A resin pellet of the present invention includes a resin base material and a plurality of microparticles embedded in the resin base material. The resin pellet is covered with the plurality of microparticles on the surface of the resin base material. According to the present invention, it is possible to prevent detachment of the microparticles to be applied on the resin base material and to effectively suppress blocking of resin pellets.

         2 . The resin pellet according to  claim 1 , wherein said microparticles are embedded in said resin base material by dispersing said microparticles and said resin base material in a softened state in a liquid. 
     
     
         3 . The resin pellet according to  claim 1 , wherein said microparticles contain a resin component. 
     
     
         4 . The resin pellet according to  claim 1 , wherein said resin base material and said microparticles contain the same resin component. 
     
     
         5 . The resin pellet according to  claim 1 , wherein said resin base material contains an ethylene-vinyl acetate copolymer. 
     
     
         6 . The resin pellet according to  claim 5 , wherein the content of vinyl acetate in said ethylene-vinyl acetate copolymer contained in said resin base material is 25 to 50 mass %. 
     
     
         7 . The resin pellet according to  claim 1 , wherein said microparticles contain an ethylene-vinyl acetate copolymer. 
     
     
         8 . The resin pellet according to  claim 7 , wherein the content of vinyl acetate in said ethylene-vinyl acetate copolymer contained in said microparticles is 5 to 20 mass %. 
     
     
         9 . The resin pellet according to  claim 1 , wherein both said resin base material and said microparticles comprise an ethylene-vinyl acetate copolymer. 
     
     
         10 . The resin pellet according to  claim 1 , wherein the average particle size of said microparticles is equal to or less than 20 μm. 
     
     
         11 . The resin pellet according to  claim 1 , wherein the shore hardness of said microparticles is higher than the shore hardness of said resin base material. 
     
     
         12 . The resin pellet according to  claim 1 , wherein the degree of crystallinity of said microparticles by the X-rays is higher than the degree of crystallinity of said resin base material by the X-rays. 
     
     
         13 . The resin pellet according to  claim 1 , wherein the Vicat softening point of said microparticles is higher than the Vicat softening point of said resin base material.
