Wood composite panel containing diiodomethyl-p-tolylsulfone

Abstract

Disclosed is a method for the production of a wood composite board comprising the steps of: providing a quantity of wood in the form of wood strands; drying the wood strands; coating the wood strands with a binder composition and diiodomethyl-p-tolylsulfone to from coated and treated strands; forming a mat from the coated and treated strands; pressing the mat, at a high temperature, to form the wood composite board having a final thickness.

1 . A method for the production of a wood composite board comprising the steps of: 
 providing a quantity of wood in the form of wood strands;    drying the wood strands;    coating the wood strands with a binder composition and diiodomethyl-p-tolylsulfone to from coated and treated strands;    forming a mat from the coated and treated strands;    pressing the mat, at a high temperature, to form the wood composite board having a final thickness.    
   
   
       2 . The method according to  claim 1 , wherein the high temperature is from about 175° C. to about 260° C.  
   
   
       3 . The method according to  claim 1 , wherein the mat is formed from alternating layers, with the coated strands in adjacent layers being oriented substantially perpendicular to each other.  
   
   
       4 . The method according to  claim 1 , wherein the mat is formed from layers, wherein in each layer the strands are aligned in substantially the same direction.  
   
   
       5 . The method according to  claim 1 , wherein the binder composition includes an isocyanate binder resin.  
   
   
       6 . The method according to  claim 1 , wherein the wood board is in the form of OSB.  
   
   
       7 . The panel according to  claim 1 , wherein the diiodomethyl-p-tolylsulfone is present in a concentration range of about 0.25 wt % to about 1.50 wt %.
