Phenolic-formaldehyde resole-polymerized unsaturated fatty acid modified binder composition for bonded mat

Claim 1

A HARDENABLE, AQUEOUS BINDER COMPOSITION CONTAINING FROM 12 TO 22 PERCENT OF SOLIDS CONSISTING ESSENTIALLY OF FROM 5 TO 35 PERCENT OF POLYMERIZED UNSATURATED FATTY ACIDS HAVING A CHAIN LENGTH OF FROM 10 TO 22 CARBON ATOMS AND FROM 10 TO 40 PERCENT OF A HEAT-HARDENABLE PHENOLAMINO COMPOUND-FORALDEHYDE RESOLE WHEREIN THE FORMALDEHYDE TO PHENOL MOL RATIO IS AT LEAST 1 1/4:1 BUT NOT GREATER THAN ABOUT 23/4:1, 5-60 PERCENT OF BONE GLUE, AND UP TO ABOUT 50 PERCENT OF A WATER SOLUBLE FILM-FORMING CONSTITUENT SELECTED FROM THE GROUP CONSISTING OF STARCH, DEXTRINIZED STARCH AND CATIONIC STARCHS PROVIDED THAT THE SUM OF BONE GLUE AND FILM FORMER IS FROM 35 PERCENT TO 75 PERCENT.

Claim 3

A METHOD FOR PREPARING A HARDENED BINDER COMPOSITION COMPRISING DISSOLVING IN WATER A WATER SOLUBLE SOLID DISPERSING AGENT FOR POLYMERIZED FATTY ACID, DISPERSING IN THE RESULTING SOLUTION, WITH AGITATION, POLYMERS OF UNSATURATED FATTY ACIDS HAVING A CHAIN LENGTH OF FROM 10 TO 22 CARBON ATOMS, AND MIXING WITH THE RESULTING DISPERSION A HEAT HARDENABLE PHENOL-AMINO COMPOUND-FORMALDEHYDE RESOLED WHEREIN THE FORMALDEHYDE TO PHENOL MOL RATION IS AT LEAST 1 1/4:1 BUT NOT GREATER THAN ABOUT 2 3/4:1 AND A WATER SOLUBLE FILM-FORMING CONSTITUENT SELECTED FROM THE GROUP CONSISTING OF STARCH, DEXTINIZED STARCH AND CATIONIC STARCH, AND WHEREIN THE PROPORTIONS OF THE SEVERAL INGREDIENTS ARE SUCH THAT THE BINDER COMPOSITION HAS A SOLIDS CONTENT OF FROM 5 PERCENT TO 35 PERCENT, AND THE SOLIDS CONSIST ESSENTIALLY OF FROM 5 PERCENT TO 40 PERCENT OF THE POLYMERIZED UNSATURATED FATTY ACIDS, FROM 10 PERCENT TO 40 PERCENT OF THE HEAT-HARDENABLE PHENOLIC RESOLE, FROM 5 PERCENT TO 70 PERCENT OF THE WATERSOLUBLE SOLID DISPERSING AGENT, AND UP TO ABOUT 70 PERCENT OF THE WATER-SOLUBLE FILM-FORMING CONSTITUENT, PROVIDED THAT THE SUM OF THE DISPERSING AGENT AND FILM FORMER IS FROM 35 PERCENT TO 75 PERCENT.

Claim 4

A METHOD FOR PREPARING A HARDENED BINDER COMPOSITION COMPRISING DISSOLVING IN WATER A WATER SOLUBLE SOLID DISPERSING AGENT FOR POLYMERIZED FATTY ACID, DISPERSING IN THE RESULTING SOLUTION, WITH AGITATION, POLYMERS OF UNSATURATED FATTY ACIDS HAVING A CHAIN LENGTH OF FROM 10 TO 22 CARBON ATOMS, AND MIXING WITH THE RESULTING DISPERSION A HEAT HARDENABLE PHENOL-AMINO COMPOUND-FORMALDEHYDE RESOLED WHEREIN THE FORMALDEHYDE TO PHENOL MOL RATION IS AT LEAST 1 1/4:1 BUT NOT GREATER THAN ABOUT 2 3/4:1 AND A WATER SOLUBLE FILM-FORMING CONSTITUENT SELECTED FROM THE GROUP CONSISTING OF STARCH, DEXTINIZED STARCH AND CATIONIC STARCH, AND WHEREIN THE PROPORTIONS OF THE SEVERAL INGREDIENTS ARE SUCH THAT THE BINDER COMPOSITION HAS A SOLIDS CONTENT OF FROM 5 PERCENT TO 35 PERCENT, AND THE SOLIDS CONSIST ESSENTIALLY OF FROM 5 PERCENT TO 40 PERCENT OF THE POLYMERIZED UNSATURATED FATTY ACIDS, FROM 10 PERCENT TO 40 PERCENT OF THE HEAT-HARDENABLE PHENOLIC RESOLE, FROM 5 PERCENT TO 70 PERCENT OF THE WATERSOLUBLE SOLID DISPERSING AGENT, AND UP TO ABOUT 70 PERCENT OF THE WATER-SOLUBLE FILM-FORMING CONSTITUENT, PROVIDED THAT THE SUM OF THE DISPERSING AGENT AND FILM FORMER IS FROM 35 PERCENT TO 75 PERCENT.
