摘要： A method to produce a thin-layer lignocellulosic composite includes forming a lignocellulosic composite mixture including at least one type of lignocellulosic fiber having a predetermined moisture content of at least about 4 wt %, at least about 1 wt % of an organic isocyanate resin, at least about 0.1 wt % of a tackifier, and at least about 0.1 wt % release agent, wherein the mixture is substantially free of added wax. The method further includes pre-pressing the mixture into a loose formed mat and pressing the mat between two dies at an elevated temperature and pressure and/or a sufficient time to further reduce the thickness of the mat to form a thin-layer composite of predetermined thickness, and to allow the isocyanate resin to interact with the lignocellulosic fiber such that the resultant thin-layer composite has a predetermined resistance to moisture.
