Shot material and method of blasting

Abstract

It is an object of the present invention to provide a blasting method and a shot material, which are very practical both in the cost and the treatment performance. (a) A shot material containing a styrene ion-exchange resin or a waste material caused therefrom, or/and a dried sludge-derived material, (b) a shot material containing a resin which is comprised of a resin containing a rubber component and a resin containing no rubber component, and (c) a shot material containing at least one component selected from the group consisting of an epoxy resin composition and inorganic filler, and a blasting method using the shot material.

1 . A blasting treatment method comprising at least the step of blasting shot material comprising a resin (C) comprised of a resin (A) containing a rubber component and a resin (B) containing no rubber component.  
     
     
         2 . The blasting treatment method according to  claim 1 , wherein at least one of said resin (A) containing a rubber component and said resin (B) containing no rubber component is a used resin.  
     
     
         3 . A blasting method of  claim 1 , wherein said resin (C) is a used resin salvaged from a used magnetic recording product.  
     
     
         4 . The blasting method according to  claim 1 , wherein the weight ratio of said resin (B) containing no rubber component to said resin (A) containing a rubber component {(B)/(A)} is in the range of 0.001 to 5.  
     
     
         5 . The blasting method according to  claim 1 , wherein the content of said resin (C) in said shot material is 0.1 to 100% by weight.  
     
     
         6 . The blasting method according to  claim 1 , wherein said resin (A) containing a rubber component is a HIPS (high impact polystyrene) and/or ABS (acrylonitrile/butadiene/styrene resin), and said resin (B) containing no rubber component is a PS (polystyrene) and/or AS (acrylonitrile/styrene resin).  
     
     
         7 . A shot material comprising a resin (C) comprised of a resin (A) containing a rubber component and a resin (B) containing no rubber component.  
     
     
         8 . The shot material according to  claim 7 , wherein at least one of said resin (A) containing a rubber component and said resin (B) containing no rubber component is a used resin.  
     
     
         9 . The shot material according to  claim 7 , wherein said resin (C) is a used resin salvaged from a used magnetic recording product.  
     
     
         10 . The shot material according to  claim 7 , wherein the weight ratio of said resin (B) containing no rubber component to said resin (A) containing a rubber component {(B)/(A)} is in the range of 0.001 to 5.  
     
     
         11 . The shot material according to  claim 7 , wherein the content of said resin (C) in said shot material is 0.1 to 100% by weight.  
     
     
         12 . The shot material according to  claim 7 , wherein said resin (A) containing a rubber component is a HIPS (high impact polystyrene) and/or ABS (acrylonitrile/butadiene/styrene resin), and said resin (B) containing no rubber component is a PS (polystyrene) and/or AS (acrylonitrile/styrene resin).  
     
     
         13 . An industrial product having a surface resulting from blasting with shot material comprising a resin (C) comprised of a resin (A) containing a rubber component and a resin (B) containing no rubber component.  
     
     
         14 . A method of processing a waste material at least comprising the step of blasting the waste material with shot material comprising a resin (C) comprised of a resin (A) containing a rubber component and a resin (B) containing no rubber component.  
     
     
         15 . A product obtained by a blasting a waste product with shot material comprising a resin (C) comprised of a resin (A) containing a rubber component and a resin (B) containing no rubber component.
