Resin composition and manufacturing method therefor

Abstract

The present invention relates to resin composition with superior antioxidant properties, mechanical strength and insulating properties. A mixture of a thermoplastic resin in pellet or granular form and water is heated under pressure at a subcritical condition of the water to melt the thermoplastic resin, and the melted resin is cooled.

What is claimed is:  
     
         1 . A resin composition, wherein a mixture of a thermoplastic resin in pellet or granular form and water is melted using heat and pressure under a subcritical condition of the water, and the melted resin is cooled.  
     
     
         2 . The resin composition of  claim 1 , wherein the water is natural unchanged water.  
     
     
         3 . The resin composition, of  claim 1 , wherein the water is purified water or distilled water containing antioxidizing substances produced by groups of effective microorganisms.  
     
     
         4 . The resin composition of  claim 1 , wherein the water is purified water or distilled water.  
     
     
         5 . The resin composition according to  claim 1 , wherein the thermoplastic resin is polyethylene or polypropylene.  
     
     
         6 . The resin composition according to  claim 1 , wherein the melted resin is cooled using cold water with impurities removed.  
     
     
         7 . A method for manufacturing a resin composition comprising a first stage wherein a thermoplastic resin in pellet or granular form is mixed and stirred in water, a second stage wherein the mixture is heated under a subcritical condition of the water and the thermoplastic resin is melted, and a third stage wherein the melted resin obtained in the second stage is cooled.  
     
     
         8 . The method for manufacturing a resin composition according to  claim 7 , wherein the water is natural unchanged water.  
     
     
         9 . The method for manufacturing a resin composition according to  claim 7 , wherein the water is purified water or distilled water containing antioxidizing substances produced by groups of effective microorganisms.  
     
     
         10 . The method for manufacturing a resin composition according to  claim 7 , wherein the water is purified water or distilled water.  
     
     
         11 . The method according to  claim 7 , wherein the melted resin obtained in the second stage is cooled using cold water with impurities removed.  
     
     
         12 . The method for manufacturing a resin composition according to  claim 7 , wherein the thermoplastic resin is polyethylene or polypropylene.  
     
     
         13 . The resin composition of  claim 3 , wherein the composition is used to insulate and rustproof electrical wiring.  
     
     
         14 . The resin composition of  claim 3 , wherein the composition is used to line pipes so that the pipes remain free of rust.
