Abstract
A particleboard includes a fiber component and an adhesive composition including a mixture of a modified guayule resin and soy protein. The modified guayule resin can be a base-solvent modified guayule resin or an H2O2-modified guayule resin. The fiber component can be a natural fiber such as a natural fiber selected from guayule bagasse, wood chips, wood particles, wood waste straw, wood fiber, and any combination thereof. The particleboard is formed by mixing the adhesive composition with the fiber component, introducing the mixture to a press, and pressing the mixture in the press.
Claims14
A particleboard comprising:
- a fiber component;
- and
- an adhesive composition comprising a mixture of a base-solvent modified guayule resin and soy protein,
- wherein said base-solvent modified guayule resin is formed by:
- forming a resin mixture by mixing an unmodified guayule base resin with a solvent mixture, the solvent mixture comprising acetone,
- mixing a base with the resin mixture,
- reacting the base with the unmodified guayule base resin via a saponification process within the resin mixture, and
- extracting a bottom phase of the base-solvent modified guayule resin in acetone.
A method for forming particleboard, comprising:
- forming an adhesive composition comprising a base-solvent modified guayule resin and soy protein;
- mixing the formed adhesive composition with a fiber component to form a mixture;
- introducing the mixture to a press;
- and
- pressing the mixture in the press at forces ranging from 0.75 to 25 megaPascals (108 to 3625 pounds per square inch) and at temperatures ranging from 110 to 190 degrees Celsius wherein said step of forming an adhesive composition comprises:
- forming a base-solvent modified guayule resin;
- forming a soy protein slurry comprising a soy protein;
- and mixing said modified guayule resin with said soy protein slurry, wherein said step of forming a base-solvent modified guayule resin comprises:
- forming a resin mixture by mixing an unmodified base resin with a solvent mixture, the solvent mixture comprising acetone;
- mixing NaOH with the resin mixture;
- reacting the NaOH with the guayule base resin via a saponification process;
- and extracting a bottom phase of the base-solvent modified guayule resin in acetone.
