US 12,630,705 B2 · Binder compositions and composite

Abstract

Binder compositions and processes for making and using same. In some embodiments, the binder composition can include a urea-based compound, a bifunctional quaternary ammonium salt, and an aldehyde-based resin. In some embodiments, a resinated substrate can include a plurality of substrates and the binder composition. In some embodiments, a process for making a composite product can include contacting a plurality of substrates with the binder composition. The process can also include heating the resinated substrate to at least partially cure the aldehyde-based resin to produce the composite product. In some embodiments, a composite product can include the plurality of substrates and the aldehyde-based resin at least partially cured. In some embodiments, the plurality of substrates can include lignocellulosic substrates. In other embodiments, the plurality of substrates can include glass fibers.

Dependent claims

A binder composition, comprising:

a urea-based compound, a bifunctional quaternary ammonium salt;
and an aldehyde-based resin, wherein the urea-based compound and the bifunctional quaternary ammonium salt are mixed with one another to produce an aldehyde scavenger that is mixed with the aldehyde-based resin to produce the binder composition, and wherein the aldehyde scavenger has a molar ratio of the urea-based compound to the bifunctional quaternary ammonium salt of about 1.2:1 to about 2.8:1.
