Process for particleboard manufacture

摘要

Improved particleboard and methods for fabricating improved particleboard (e.g., natural fiber/material-based particleboard) are disclosed. More particularly, the present disclosure provides systems/methods for fabricating particleboard (e.g., formaldehyde-free particleboard) utilizing natural fibers/materials (e.g., lignocellulosic materials), wherein the particleboard has improved performance characteristics and/or mechanical properties. Methods for fabricating fiber-reinforced biocomposites (e.g., natural fiber-reinforced wheat gluten biocomposites) are disclosed. For example, systems/methods for fabricating particleboard from lignocellulosic materials (e.g., coconut materials), along with a binder material (e.g., wheat gluten), are provided. In general, the fiber or lignocellulosic material is treated with sodium hydroxide and/or a silane coupling agent as an adhesion promoter to enhance interfacial adhesion between the fiber and the binder. For example, (3-triethoxysilylpropyl)-t-butylcarbamate (MISO) (a masked isocyanate functional silane) was utilized to improve interfacial adhesion between the binder and the natural fibers.
