US 9,868,857 B2 · Composite products containing a powdered binder and methods for making and using same

Abstract

Composite products, powdered binders, resinated furnishes, and methods for making and using same. In one example, a composite product can include a plurality of lignocellulose substrates and an at least partially cured, powdered binder. Prior to curing the powdered binder can include about 5 wt % to about 95 wt % of a powdered carbohydrate, and about 5 wt % to about 95 wt % of a powdered nitrogen-containing compound, where the weight percent values are based on a total weight of the powdered carbohydrate and the powdered nitrogen-containing compound. The powdered carbohydrate can include a monosaccharide, a disaccharide, or a mixture thereof. The powdered nitrogen-containing compound can include an ammonium compound, an alkylammonium compound, an amino acid, a hydrate thereof, a salt thereof, or any mixture thereof.

A method for producing a composite product, comprising:

contacting a plurality of lignocellulose substrates with a powdered binder to produce a mixture, wherein the powdered binder comprises:
about 5 wt % to about 95 wt % of a powdered carbohydrate;
and
about 5 wt % to about 95 wt % of a powdered nitrogen-containing compound,
wherein:
