20090275699 | Starch containing formaldehyde-free thermoset binders for fiber products - Binder compositions are described that include a carboxyl-containing polymer, a cross-linking agent, and a starch compound having a molecular weight greater than about 10,000 g/mol. In addition, fiber products are described that include mineral or polymeric fibers and a binder prepared from an aqueous composition that includes a carboxyl-containing polymer, a cross-linking agent, and a starch having a molecular weight greater than 10,000 g/mol. | 11-05-2009 |
20130125783 | FORMALDEHYDE-FREE BINDER COMPOSITIONS AND METHODS OF MAKING THE BINDERS UNDER CONTROLLED ACIDIC CONDITIONS - Formaldehyde-free binder compositions are described that include an aldehyde or ketone, a reaction product between a polyamine and an organic anhydride, and an acidic compound. The acidic compound may be an organic acid, an acidic catalyst, or both. The acidic compound is supplied in quantities that lower the pH of the binder composition to about 5 or less. The binder compositions may be used in methods of binding fiberglass and the resulting fiberglass products have an improved tensile strength due to the addition of the acidic compound. | 05-23-2013 |
20130133548 | CURABLE FIBERGLASS BINDER COMPRISING SALT OF INORGANIC ACID - Formaldehyde-free binder compositions are described that include an aldehyde or ketone, a nitrogen-containing salt of an inorganic acid, and an acidic compound. The acidic compound may be an organic acid, such as maleic acid or citric acid among others. The acidic compound is supplied in quantities that lower the pH of the binder composition to about 5 or less. The binder compositions may be used in methods of binding fiberglass and the resulting fiberglass products have an improved tensile strength due to the addition of the acidic compound. | 05-30-2013 |
20130231023 | FORMALDEHYDE-FREE PROTEINACEOUS BINDER COMPOSITIONS - Binder compositions are described, where the compositions include a protein, a first crosslinking compound that includes a carbohydrate, and a second crosslinking compound that includes two or more primary amine groups. The first and second crosslinking compounds may be individually crosslinkable with each other and with the protein. Also described are fiber products that may include inorganic or organic fibers and a cured thermoset binder prepared from a protein and at least two crosslinking compounds. Additionally, methods of making fiber products are described that include providing inorganic or organic fibers, and applying a liquid binder composition to the fibers to form a fiber-binder amalgam. The liquid binder composition may include a protein and at least two crosslinking compounds that include a carbohydrate and an organic amine with two or more primary amines. The amalgam may be heated to a curing temperature to form the fiber product. | 09-05-2013 |
20140027662 | FORMALDEHYDE-FREE BINDER COMPOSITIONS AND METHODS OF MAKING THE BINDERS - Formaldehyde-free binder compositions are described that include an aldehyde or ketone, an organic anhydride, an alkanol amine, and a nitrogen-containing salt of an inorganic acid. The binder compositions may be applied to fibers, such as glass fibers, to make formaldehyde-free, fiber-reinforced composites. Methods of making fiber-reinforced composites are also described, where such methods may include mixing an alkanol amine with an organic anhydride to make a first mixture, and adding a reducing sugar to the first mixture to make a second mixture. A nitrogen-containing salt may be added to the second mixture to make a binder composition, which may be applied to fibers to form a binder-fiber amalgam. The amalgam may be heated to cure the binder composition and form the fiber-reinforced composite. | 01-30-2014 |
20140134497 | SOY PROTEIN AND CARBOHYDRATE CONTAINING BINDER COMPOSITIONS - Soy protein and carbohydrate containing binder compositions are described. The binder compositions may include a carbohydrate, a nitrogen-containing compound, and a soy protein. The binder compositions may also optionally include thickening agents such as modified celluloses and polysaccharides. | 05-15-2014 |
20140134909 | VISCOSITY MODIFIED FORMALDEHYDE-FREE BINDER COMPOSITIONS - Viscosity-modified carbohydrate binder compositions are described. The binder compositions may include a carbohydrate, a nitrogen-containing compound, and a thickening agent. The binder compositions may have a Brookfield viscosity of 7 to 50 centipoise at 20° C. The thickening agents may include modified celluloses such as hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC), and polysaccharides such as xanthan gum, guar gum, and starches. | 05-15-2014 |
20140308453 | REDUCED SALT PRECIPITATION IN CARBOHYDRATE CONTAINING BINDER COMPOSITIONS - Aqueous binder compositions with reduced rates of salt precipitation are described. The compositions may include a carbohydrate and a sequestrant for sequestering one or more multivalent ions (e.g., Ca | 10-16-2014 |
20150050857 | FORMALDEHYDE-FREE PROTEINACEOUS BINDER COMPOSITIONS - Binder compositions are described, where the compositions include a protein, a first crosslinking compound that includes a carbohydrate, and a second crosslinking compound that includes two or more primary amine groups. The first and second crosslinking compounds may be individually crosslinkable with each other and with the protein. Also described are fiber products that may include inorganic or organic fibers and a cured thermoset binder prepared from a protein and at least two crosslinking compounds.
