A patent application (Publication Number: US20240001587A1) outlines a method for producing a manufactured wood product with surface protection against fungal and insect attack. The method involves forming bottom, core, and top layers of a manufactured wood mat with lignocellulosic strands treated with zinc borate at specific concentrations. Heat and pressure are then applied to form the final product. Additional steps include blending all strands with a base concentration of zinc borate and adjusting the concentration in specific layers to achieve the desired protection levels.
Furthermore, the method includes incorporating a preservative composition with a concentration of zinc borate of at least 2.0% into the surface layers of a multi-layered composite wood product. This composition helps protect the product against fungal and insect attacks. The composite wood product can be customized with additional features such as resin-impregnated paper overlay, radiant barrier layer, or insulation layer to enhance its properties. Overall, the patent application aims to provide a comprehensive method for producing wood products with enhanced surface protection and customizable features to meet various requirements in construction and other industries.
