Methods for producing binders and combustible composite materials and compositions produced therefrom

摘要

Methods and compositions are provided for producing thermoset, water repellent binders particularly effective for forming combustible composite materials. The binders include a mixture of an alkaline protein hydrolyzate and a bio-oil or an acidic protein hydrolyzate and a lignin compound. Desirably, the binders and the resulting combustible composite materials are substantially free of formaldehyde.

主权项

1. A method for producing a thermosetting water repellent binder comprising:
combining a protein hydrolyzate and a second component, wherein the protein hydrolyzate comprises an alkaline protein hydrolyzate having a pH of about 8 to about 13 and the second component comprises an acidic pyrolytic bio-oil having a pH of about 1 to about 4; and exothermally reacting the protein hydrolyzate and the second component to form a cross-linked thermosetting water repellent binder.
