Adhesion Composition and Textile Materials and Articles Treated Therewith

Abstract

This invention relates to improved adhesion compositions and textile materials and articles treated therewith. The improved adhesion composition comprises a non-crosslinked resorcinol-formaldehyde and/or resorcinol-furfural condensate (or a phenol-formaldehyde condensate that is soluble in water), a rubber latex, and an aldehyde component such as 2-furfuraldehyde. The composition may be applied to textile substrates and used for improving the adhesion between the treated textile substrates and rubber materials. End-use articles that contain the treated textile-rubber composite include, without limitation, automobile tires, belts, and hoses as well as printing blankets.

1 . A method for synthesizing an improved adhesion composition comprising the steps of:
 (a) forming an aqueous mixture comprising (i) a water soluble, phenolic condensate material selected from the group consisting of a non-crosslinked phenolic condensate, a non-crosslinked resorcinol-furfuraldehyde condensate, and a phenol-formaldehyde condensate; (ii) a latex component; (iii) a base component; and (iv) an aldehyde component represented by structure (2) or (3):   
       
         
           
           
               
               
           
         
         wherein R 1 , R 2  and R 3  may be independently selected from the group consisting of alkyl, aryl, halo, hydrogen, and carboxylic functional groups; 
         wherein the water soluble condensate material contains sufficient resorcinol functional groups or phenol groups to allow for a reaction between the condensate material and the aldehyde component; and 
         (b) allowing the mixture to age at room temperature for at least about 8 to 24 hours. 
       
     
     
         2 . The method of  claim 1 , wherein the water soluble, phenolic condensate material is a resorcinol formaldehyde resin. 
     
     
         3 . The method of  claim 1 , wherein the aldehyde component is represented by structure (2). 
     
     
         4 . The method of  claim 1 , wherein the aldehyde component is represented by structure (3). 
     
     
         5 . The method of  claim 1 , wherein the latex component is selected from the group consisting of epoxy resin, functional rubber latex, an elastomer latex having no unsaturated double bonds, unvulcanized rubber latex, and mixtures thereof. 
     
     
         6 . The method of  claim 5 , wherein the latex component is unvulcanized rubber latex. 
     
     
         7 . The method of  claim 1 , wherein the base component is selected from the group consisting of sodium hydroxide, potassium hydroxide, ammonium hydroxide, sodium carbonate, and mixtures thereof.
