METHODS FOR MAKING LIGNOCELLULOSE CONTAINING COMPOSITE PRODUCTS

摘要

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° 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° C. to about 300° C. to produce a composite product. The composite product can have a density less than 1 g/cm3 and an internal bond strength of at least 0.35 MPa.

1. A method for making a composite product, comprising:
combining a plurality of lignocellulose substrates and an oxidant to produce a mixture; and heating the mixture to a temperature of at least 60° C. to about 300° C. to produce a composite product having an internal bond strength of at least 0.3 MPa, as measured according to ASTM D1037-06a, wherein the mixture that is heated comprises at least 11 wt % of the oxidant initially combined with the plurality of lignocellulose substrates.
