Embodiment 1
[0029] 100 parts of 20-40% wood chips, 0.1 parts of tea powder, 1 part of polyvinyl formal, 3 parts of urea, 1 part of formaldehyde, 0.5 parts of melamine, 0.5 parts of polyvinyl alcohol, 0.6 parts of water glass, 0.1 parts The elongated foam-like three-dimensional graphene that embodiment 3 makes, 0.01 part of carbon nanofibers are mixed together, obtain base material type mixture; Then water glass is dissolved in the formaldehyde aqueous solution, then polyvinyl formal, urea, melamine , polyvinyl alcohol to mix evenly to obtain a viscous type mixture; mix the viscous type mixture with the substrate type mixture, and dry to a moisture content of about 11%; then pre-press the dried mixture into a billet, and then cold isostatic pressing Process it into slabs; warm and isostatically press the obtained slabs, then cool, temper and sand them to obtain particle boards. Wherein, the hot isothermal pressing temperature is 210° C., and the warm isostatic pressing pressure is 30 MPa. ...
