Surfactant modified oils for dust control of loose-fill insulation

Abstract

The present invention serves to substantially improve the dust capture property of dedusting oils, by modifying these oils with nonionic and/or cationic surfactants. The application of surfactant modified oils reduces dust that is generated when loose-fill insulation is installed.

1 . A method of controlling dust formation in loose-fill insulation, comprising: 
 applying to said loose-fill insulation dedusting oil modified with an additive consisting essentially of a surfactant of an amount to control dust formation while the loose-fill insulation is in a fiberized state adapted for pneumatic installation.    
     
     
         2 . The method as recited in  claim 1 , wherein said combination is applied to said loose-fill insulation in an amount of from about 0.5-2.5% by weight.  
     
     
         3 . The method as recited in  claim 1 , wherein said surfactant is nonionic.  
     
     
         4 . The method as recited in  claim 1 , wherein said surfactant is cationic.  
     
     
         5 . The method as recited in  claim 1 , wherein said insulation is installed pneumatically.  
     
     
         6 . The method as recited in  claim 3 , wherein said surfactant is glycerol monooleate.  
     
     
         7 . The method is recited in  claim 1 , wherein said combination is applied to said loose-fill insulation in an amount of about 2% by weight.  
     
     
         8 . The method as recited in  claim 3  wherein said nonionic surfactant is a monoester of an unsaturated or saturated acid.  
     
     
         9 . The method as recited in  claim 8  wherein said unsaturated acid is linoleic or linolenic acid.  
     
     
         10 . The method as recited in  claim 8  wherein said saturated acid is a C12 to C18 lauric, myristic, palmitic to stearic acid.  
     
     
         11 . The method as recited in  claim 3  wherein said nonionic surfactant is a diester or triester of an unsaturated or saturated acid.  
     
     
         12 . A method of controlling dust formation in loose-fill insulation, comprising: 
 applying to said loose-fill insulation dedusting oil modified with an additive consisting essentially of a nonionic surfactant of an amount to control dust formation while the loose-fill insulation is in a fiberized state adapted for pneumatic installation.    
     
     
         13 . The method as recited in  claim 12 , wherein said insulation is installed pneumatically.  
     
     
         14 . The method as recited in  claim 13 , wherein said combination is applied to said loose-fill insulation in an amount of from about 1.5-2.5% by weight.  
     
     
         15 . The method as recited in  claim 13 , wherein said nonionic surfactant is glycerol monooleate.  
     
     
         16 . The method as recited in  claim 12  wherein said nonionic surfactant is a monoester of an unsaturated or saturated acid.  
     
     
         17 . The method as recited in  claim 13  wherein said unsaturated acid is linoleic or linolenic acid.  
     
     
         18 . The method as recited in  claim 13  wherein said saturated acid is a C12 to C18 lauric, myristic, palmitic to stearic acid.  
     
     
         19 . The method as recited in  claim 12  wherein said nonionic surfactant is a diester or triester of an unsaturated or saturated acid.
