Abstract

Composite Maillard-resole binders to produce or promote cohesion in non-assembled or loosely assembled matter.

First claim

1 .- 67 . (canceled)

68 . A binder, comprising: a mixture of uncured resole resin and Maillard reactants, wherein said mixture is an aqueous solution.

69 . The binder of claim 68 , wherein the mixture is substantially free of melanoidins.

70 . The binder of claim 68 , wherein the resole resin is prereacted with urea.

71 . The binder of claim 68 , wherein the resole resin contains urea and is not prereacted.

72 .- 74 . (canceled)

75 . The binder of claim 68 , wherein the Maillard reactants comprise a mixture of:
(a) a monosaccharide; and (b) an ammonium salt of a polycarboxylic acid.

76 . The binder of claim 75 , wherein the ratio of the number of moles of the ammonium salt to the number of moles of the monosaccharide is in the range from about 1:4 to about 1:15.

77 .- 78 . (canceled)

79 . The binder of claim 68 , wherein the pH of the binder is in the range from greater than about 7 to less than or equal to about 10.

80 . The binder of claim 75 , wherein the monosaccharide is selected from the group consisting of dextrose, xylose, fructose, dihydroxyacetone, and mixtures thereof.

81 . The binder of claim 75 , wherein the monosaccharide is dextrose.

82 . The binder of claim 75 , wherein the polycarboxylic acid is a monomeric polycarboxylic acid.

83 . The binder of claim 82 , wherein the monomeric polycarboxylic acid is selected from the group consisting of an unsaturated aliphatic polycarboxylic acid, a saturated aliphatic polycarboxylic acid, an aromatic polycarboxylic acid, an unsaturated cyclic polycarboxylic acid, a saturated cyclic polycarboxylic acid, hydroxy-substituted derivatives thereof, anhydrides thereof, and mixtures thereof.

84 . The binder of claim 75 , wherein the polycarboxylic acid is a polymeric polycarboxylic acid.

85 . The binder of claim 84 , wherein the polymeric polycarboxylic acid is selected from the group consisting of polyacrylic acid, polymethacrylic acid, and polymaleic acid, copolymers thereof, anhydrides thereof, and mixtures thereof.

86 . The binder of claim 81 , wherein the polycarboxylic acid is selected from the group consisting of citric acid, maleic acid, tartaric acid, malic acid, succinic acid, and mixtures thereof.

87 . (canceled)

88 . The binder of claim 68 , wherein the binder further comprises a silicon-containing compound.

89 .- 90 . (canceled)

91 . The binder of claim 88 , wherein the silicon-containing compound is selected from the group consisting of gamma-aminopropyltriethoxysilane, gamma-glycidoxypropyltrimethoxysilane, aminoethylaminopropyltrimethoxysilane, n-propylamine silane, and mixtures thereof.

92 . (canceled)

93 . The binder of claim 68 , wherein the binder further comprises a non-carbohydrate polyhydroxy reactant.

94 . The binder of claim 93 , wherein the non-carbohydrate polyhydroxy reactant is selected from the group consisting of trimethylolpropane, glycerol, pentaerythritol, sorbitol, 1,5-pentanediol, 1,6-hexanediol, polyTHF 650 , polyTHF 250 , textrion whey, polyvinyl alcohol, partially hydrolyzed polyvinyl acetate, fully hydrolyzed polyvinyl acetate, and mixtures thereof.

95 . The binder of claim 68 , wherein the binder further comprises a corrosion inhibitor, said inhibitor capable of decreasing the corrosivity of glass fibers.

96 . The binder of claim 95 , wherein the corrosion inhibitor is selected from the group consisting of dedusting oil, monoammonium phosphate, sodium metasilicate pentahydrate, melamine, tin(II) oxalate, and a methylhydrogen silicone fluid emulsion.

97 .- 104 . (canceled)
