METHODS AND SYSTEMS FOR ADJUSTING THE COMPOSITION OF A BINDER SYSTEM CONTAINING TWO OR MORE RESINS

摘要

Methods and systems for preparing a binder system are provided. The method can include combining a first resin and a second resin to produce a first binder system. The first binder system can be applied to a first plurality of lignocellulose substrates and at least partially cured to produce a first composite product. The method can also include monitoring one or more process variables. The one or more monitored process variables can be evaluated. An amount of the first resin, the second resin, or both combined with one another can be adjusted in response to the evaluation of the one or more monitored process variables to produce a second binder system.

1. A binder system for making lignocellulose composite products, comprising:
a first resin comprising an aldehyde based resin, and a second resin comprising (a) a mixture of Maillard reactants, (b) a copolymer of a vinyl aromatic derived unit and at least one of maleic anhydride and maleic acid, (c) a polyamide-epichlorohydrin polymer, (d) an adduct or polymer of styrene, at least one of maleic anhydride and maleic acid, and at least one of an acrylic acid and an acrylate, (e) a polyacrylic acid based binder, (f) a polyvinyl acetate, (g) a polymeric methylene diisocyanate, or (h) any combination thereof, wherein the binder system comprise about 75 wt % to about 99.9 wt % of the first resin, based on a combined solids weight of the first resin and the second resin.
