Abstract
Wood-based composites, compositions for use in wood-based composites, and associated systems and methods are provided herein. Certain compositions include a mixture of alpha olefins and esters and demonstrate unique water repellant properties. The compositions may be incorporated in wood-based composites in place of traditional petroleum-based slack waxes.
Claims25
A wood composition, comprising:
- wood elements;
- a bonding resin comprising 2.0-7.0% of the dry mass of the wood elements;
- and
- a wax composition comprising 0.1-3.0% of the dry mass of the wood elements, wherein the wax composition is a mixture of alpha olefins and esters, and wherein the mass ratio of the alpha olefins to the esters is between 2:8 and 8:2.
A wax composition for use in wood-based composites, the wax composition comprising a mixture of alpha olefins and esters, wherein the alpha olefins have a molecular weight between 240 and 400 Daltons, and wherein the mass ratio of the alpha olefins to the esters is between 2:8 and 8:2.
A method of manufacturing a wood-based composite, the method comprising:
- providing wood elements;
- drying the wood elements to a moisture content of 2.0-12%;
- applying a bonding resin to the wood elements;
- applying a wax composition to the wood elements, wherein the wax composition comprises a mixture of alpha olefins and esters, and wherein the alpha olefins have a molecular weight between 240 and 400 Daltons, and wherein the mass ratio of alpha olefins to esters is between 2:8 and 8:2;
- and
- forming the wood elements into one or more wood-based composites.
