Binders, methods for making same, and methods for making composite lignocellulose products therefrom. The binder can include about 30 wt % to about 40 wt % of solids that include a urea-modified aldehyde-based resin; about 0.1 wt % to about 3 wt % of solids that include an isocyanate-based resin; about 0.1 wt % to about 12 wt % of an extender; and about 50 wt % to about 62 wt % of water, where all weight percent values are based on a total weight of the binder. The binder can have a sodium hydroxide equivalent weight alkalinity of about 3 wt % to about 9 wt %.

Aromatic alcohol-lignin-aldehyde resins and process for making and using same. In some examples, a process for making a resin can include heating a first mixture that includes a lignin, an aromatic alcohol, and a base compound to produce a second mixture that can include an activated lignin, the aromatic alcohol, and the base compound. The second mixture can be heated with an aldehyde to produce a third mixture that can include an aromatic alcohol-lignin-aldehyde resin and unreacted free aldehyde. In some examples, an aromatic alcohol-lignin-aldehyde resin can be or include a co-polymer of an activated lignin, an aromatic alcohol, and an aldehyde. A weight ratio of the activated lignin to the aromatic alcohol can be about 20:80 to about 95:5.

Methods for making composite products are provided. In at least one specific embodiment, the method can include combining a plurality of lignocellulose substrates and one or more free radical precursors to produce a mixture of the lignocellulose substrates and the one or more free radical precursors. The method can also include maintaining the mixture at a temperature less than 60&#xb0; C. for at least 10 minutes while retaining at least 11 wt % of the one or more free radical precursors charged to the mixture. The method can then include heating the mixture comprising at least 11 wt % of the one or more free radical precursors charged to the mixture to a temperature of at least 60&#xb0; C. to about 300&#xb0; C. to produce a composite product. The composite product can have a density less than 1 g/cmand an internal bond strength of at least 0.35 MPa.

Binder compositions and methods for making and using same are provided. In at least one specific embodiment, the binder composition can include at least one unsaturated compound having two or more unsaturated carbon-carbon bonds and at least one free radical precursor. At least one of the unsaturated carbon-carbon bonds can be a pi-bond that is not conjugated with an aromatic moiety and can be capable of free radical addition. The free radical precursor can be present in an amount of about 7 wt % to about 99 wt %, based on the weight of the one or more unsaturated compounds.

Binder compositions and methods for making and using same

In some examples, one or more metal-containing catalysts and one or more waxes can be mixed or otherwise combined to produce an encapsulated catalyst composition. The wax can be at least partially coated on the metal-containing catalyst. A mixture of water and the wax can be agitated or otherwise mixed, and the metal-containing catalyst can be added to or otherwise combined with the water and wax mixture to produce a wax emulsified catalyst. A plurality of lignocellulose substrates, one or more oxidants, and the encapsulated catalyst composition can be mixed or otherwise combined to produce a lignocellulose binder mixture. The lignocellulose binder mixture can be heated to produce a composite product.

Methods for making lignocellulose composite products with oxidative binders and encapsulated catalyst

A method for making a composite product can include combining a plurality of lignocellulose substrates and a binder to produce a resinated furnish. The binder can be or include a polyphenolic compound, a free radical precursor, and an unsaturated compound having two or more unsaturated carbon-carbon bonds. At least one of the unsaturated carbon-carbon bonds is a pi-bond that is not conjugated with an aromatic moiety and is capable of free radical addition. The method can also include pressing the resinated furnish between at least two surfaces in a press, where at least one of the at least two surfaces can be a porous surface, and at least partially curing the binder in the resinated furnish to produce a composite product.

Methods for making composite products containing lignocellulose substrates

Methods for making lignocellulose composite products can include combining a plurality of lignocellulose substrates, calcium lignosulfonate, and a free radical precursor to produce a mixture. The free radical precursor can include an oxidant and a catalyst. The mixture can be at least partially cured to produce a lignocellulose composite product.

Methods for making lignocellulose composite products

In some examples, a method for making a composite product can include combining a plurality of lignocellulose substrates, one or more complexed metal catalysts, one or more complexing agents, and one or more oxidants to produce a lignocellulose binder mixture and heating the lignocellulose binder mixture to produce a composite product. The lignocellulose binder mixture can have a molar ratio of the complexing agent to the complexed metal catalyst of about 0.1 or greater.

Methods for making composite products are provided. In at least one specific embodiment, the method can include combining a plurality of lignocellulose substrates, a free radical precursor, and a polyphenolic material to produce a mixture. The polyphenolic material can be in a liquid form, a solid form, or both when combined to produce the mixture. The method can also include maintaining the mixture at a temperature of less than 60&#xb0; C. for at least 10 minutes while retaining at least 11 wt % of the free radical precursor charged to the mixture. The mixture can also include heating the mixture comprising at least 11 wt % of the free radical precursors charged to the mixture to a temperature of at least 60&#xb0; C. to about 300&#xb0; C. to produce a composite product.

Compositions that include hydrophobizing agents and stabilizers and methods for making and using same are provided. In at least one specific embodiment, a composition can include about 40 wt % to about 60 wt % lignosulfonic acid or a salt thereof, about 1 wt % to about 20 wt % of a hydrophobizing agent, and about 20 wt % to about 59 wt % of a liquid medium, where all weight percents are based on the combined weight of the lignosulfonic acid or salt thereof, the hydrophobizing agent, and the liquid medium.
