Abstract
Composite cellulosic products and processes for making same. In some embodiments, the composite cellulosic product can include a plurality of cellulosic substrates and an at least partially cured binder. Prior to curing, the binder can include a mixture formed by combining magnesium oxide, water, and magnesium chloride. A weight ratio of the magnesium oxide to the magnesium chloride in the binder can be at least 2.2:1 to 8.5:1.
Claims23
A composite cellulosic product, comprising:
- an at least partially cured binder and 0.5 wt % to 10 wt % of a plurality of cellulosic substrates, based on a total weight of the composite cellulosic product, wherein, prior to curing, the binder comprises a mixture formed by combining:
- magnesium oxide,
- water, and
- magnesium chloride, wherein a weight ratio of the magnesium oxide to the magnesium chloride in the binder is at least 2.2:1 to about 8.5:1, and wherein a weight ratio of the water to the magnesium chloride in the binder is about 1.5:1 to about 4.5:1.

A process for making a composite cellulosic product, comprising:
- contacting a plurality of cellulosic substrates with a binder to produce a mixture comprising 0.5 wt % to 10 wt % of the plurality of cellulosic substrates, based on a total weight of the mixture, wherein the binder comprises:
- magnesium oxide,
- water, and
- magnesium chloride, wherein a weight ratio of the magnesium oxide to the magnesium chloride in the binder is at least 2.2:1 to 8.5:1, and wherein a weight ratio of the water to the magnesium chloride in the binder is about 1.5:1 to about 4.5:1;
- and
- allowing the mixture to set for a time period sufficient to allow the binder to at least partially cure to produce the composite cellulosic product.
