Method of producing construction material for promoting health

Abstract

The present invention provides a method of producing a health-promoting construction material. The method includes processing a construction material by use of an adhesive to which a finely pulverized powder of stone generating far-infrared radiation and/or negative ions has been incorporated. The stone generating far-infrared radiation and/or negative ions is preferably quartz porphyry, granite porphyry, tourmaline, zeolite, or a mixture thereof.

What is claimed is:  
     
         1 . A method of producing a health-promoting construction material, which method comprises processing a construction material by use of an adhesive to which a finely pulverized powder of stone generating far-infrared radiation and/or negative ions has been incorporated.  
     
     
         2 . The method according to  claim 1 , wherein the construction material is selected from among plywood, laminated veneer lumber, adhesive-laminated lumber, particleboard, and medium density fiber board (MDF).  
     
     
         3 . A method of producing a health-promoting construction material, which method comprises bonding a decorative construction material to a construction base material by use of an adhesive to which a finely pulverized powder of stone generating far-infrared radiation and/or negative ions has been incorporated.  
     
     
         4 . The method according to  claim 3 , wherein the decorative construction material is a decorative veneer plate and the construction base material is selected from among plywood, laminated veneer lumber, adhesive-laminated lumber, particleboard, and medium density fiber board (MDF).  
     
     
         5 . The method according to  claim 3 , wherein the decorative construction material is a decorative sheet and the construction base material is selected from among plywood, laminated veneer lumber, adhesive-laminated lumber, particleboard, and medium density fiber board (MDF).  
     
     
         6 . A method of producing a health-promoting construction material, which method comprises bonding a decorative construction material to an interior base material by use of an adhesive to which a finely pulverized powder of stone generating far-infrared radiation and/or negative ions has been incorporated.  
     
     
         7 . The method according to  claim 6 , wherein the decorative construction material is a decorative veneer plate and the interior base material is selected from among floor material, wall material, and ceiling material.  
     
     
         8 . The method according to  claim 6 , wherein the decorative construction material is a decorative sheet and the interior base material is selected from among floor material, wall material, and ceiling material.  
     
     
         9 . A method of producing a health-promoting construction material, which method comprises applying a coating material to a surface of a construction material, and an adhesive to which a finely pulverized powder of stone generating far-infrared radiation and/or negative ions has been incorporated is admixed with the coating material.  
     
     
         10 . The method according to  claim 9 , wherein the construction material is selected from among plywood, laminated veneer lumber, adhesive-laminated lumber, particleboard, and medium density fiber board (MDF).  
     
     
         11 . A method of producing a health-promoting construction material, which method comprises applying a coating material to an interior base material, and an adhesive to which a finely pulverized powder of stone generating far-infrared radiation and/or negative ions has been incorporated is admixed with the coating material.  
     
     
         12 . The method according to  claim 11 , wherein the interior base material is selected from among floor material, wall material, and ceiling material.  
     
     
         13 . The method according to  claim 1 , wherein the finely pulverized powder of stone generating far-infrared radiation and/or negative ions to be incorporated into the adhesive is formed from raw stone selected from the group consisting of quartz porphyry, granite porphyry, tourmaline, zeolite, and a mixture thereof.  
     
     
         14 . The method according to  claim 3 , wherein the finely pulverized powder of stone generating far-infrared radiation and/or negative ions to be incorporated into the adhesive is formed from raw stone selected from the group consisting of quartz porphyry, granite porphyry, tourmaline, zeolite, and a mixture thereof.  
     
     
         15 . The method according to  claim 6 , wherein the finely pulverized powder of stone generating far-infrared radiation and/or negative ions to be incorporated into the adhesive is formed from raw stone selected from the group consisting of quartz porphyry, granite porphyry, tourmaline, zeolite, and a mixture thereof.  
     
     
         16 . The method according to  claim 9 , wherein the finely pulverized powder of stone generating far-infrared radiation and/or negative ions to be incorporated into the coating material is formed from raw stone selected from the group consisting of quartz porphyry, granite porphyry, tourmaline, zeolite, and a mixture thereof.  
     
     
         17 . The method according to  claim 11 , wherein the finely pulverized powder of stone generating far-infrared radiation and/or negative ions to be incorporated into the coating material is formed from raw stone selected from the group consisting of quartz porphyry, granite porphyry, tourmaline, zeolite, and a mixture thereof.  
     
     
         18 . The method according to  claim 1 , wherein the adhesive is an isocyanate-resin-based adhesive.
