Method for reusing chrushed synthetic resin product

Abstract

A pulverized thermoplastic resin product such as a pulverized thermoplastic product containing a black pigment, a mixture of a pulverized thermoplastic product containing a colored pigment and a pulverized thermoplastic product containing a colored pigment, or a pulverized thermoplastic product containing two or more different colored pigments can be converted into colored reclaimed resin particles by a method comprising the steps of mixing the pulverized resin product with a white pigment and a black pigment, melting the resulting mixture, and converting the molten mixture into solid particles. The colored reclaimed resin products can be utilized in various field.

What is claimed is:  
     
         1 . A method for producing colored reclaimed resin particles which comprises the steps of: 
 preparing a molten product which comprises a mixture of a white pigment, a colored pigment, and a pulverized thermoplastic resin product to be reclaimed which is selected from the group consisting of a pulverized thermoplastic product containing a black pigment, a mixture of a pulverized thermoplastic product containing a black pigment and a pulverized thermoplastic product containing a colored pigment, and a pulverized thermoplastic product containing two or more different colored pigments; and    converting the molten product into solid particles.    
     
     
         2 . The method for producing colored reclaimed resin particles as defined in  claim 1 , wherein the step of preparing a molten product comprises a step of mixing the product to be reclaimed with the white pigment and the colored pigment, and a subsequent step of heating and melting the resulting mixture.  
     
     
         3 . The method for producing colored reclaimed resin particles as defined in  claim 1 , wherein the step of preparing a molten product comprises incorporation of a black pigment.  
     
     
         4 . The method for producing colored reclaimed resin particles defined in  claim 1 , wherein an inorganic filler is incorporated into the mixture produced in the step of preparing a molten product.  
     
     
         5 . The method for producing colored reclaimed resin particles defined in  claim 1 , wherein a thermoplastic resin is incorporated into the mixture produced in the step of preparing a molten product.  
     
     
         6 . The method for producing colored reclaimed resin particles defined in  claim 1 , wherein a thermoplastic resin and an elastomer are incorporated into the mixture produced in the step of preparing a molten product.  
     
     
         7 . The method for producing colored reclaimed resin particles defined in  claim 1 , wherein the pulverized thermoplastic resin product to be reclaimed is a pulverized bumper or interior trim taken from automobile which has no skin film thereon.  
     
     
         8 . The method for producing colored reclaimed resin particles defined in  claim 1 , wherein the pulverized thermoplastic resin product to be reclaimed comprises a thermoplastic resin selected from the group consisting of polyolefin, polyester, polystyrene, ABS resin, and polyamide.  
     
     
         9 . The method for producing colored reclaimed resin particles defined in  claim 1 , wherein the pulverized thermoplastic resin product to be reclaimed contains an elastomer.  
     
     
         10 . Colored reclaimed resin particles-produced by the method of  claim 1 .  
     
     
         11 . A method for manufacturing a resin article prepared by melting the colored reclaimed resin particles of  claim 10  under heating and molding the molten particles.
