Embodiment 1
[0014] A high-performance fiberboard, which is formed by bonding and pressing the upper surface layer, the middle layer and the lower surface layer through adhesives from top to bottom, wherein the upper surface layer and the lower surface layer are solid wood sheets, and the middle layer is modified filler particles. The particles are made of the following raw materials in parts by weight: modified wood powder 40, modified basalt fiber 10, polymethacrylate powder 5, polytetrafluoroethylene powder 4, polyethylene powder 10, aluminum oxide 3.
[0015] Further, the preparation method of the modified filler particles is as follows: put the modified wood powder and the modified basalt fiber into a mixer, mix them at a speed of 200 rpm for 20 minutes, and then add polymethacrylate powder, polytetrafluoroethylene Powder, polyethylene powder, and alumina, continue to mix and heat to 93°C, then stir for 30 minutes, granulate, and cool to obtain modified filler particles.
