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.

Abstract

The invention discloses a high performance fiberboard. The prepared board has superior bending property and impact property, and is better in mechanical properties. By reasonably compounding camphor wood powder, birch wood powder and maple wood powder, the fiberboard is enabled to be uniform in size and density and better in harmony; the wood powder is subjected to modification treatment by using glucuronolactone, acetaminophen and polyvinyl alcohol, so that the fiberboard is enabled to contain multiple active groups, the gluing effect between the fiberboard and an adhesive component is facilitated; furthermore; furthermore, the compatibility of the fiberboard with modified basalt fibers is promoted, so that the mechanical properties of the board are improved; diatomaceous earth and tapioca flour are used for modifying basalt fibers, and a porous interface is formed on the surface of basalt, so that the interaction between the basalt fibers and wood fibers as well as between the basalt fibers and an adhesive is promoted, and a framework effect is achieved; therefore, the bending strength and impact toughness of the board are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of fiberboards, in particular to a high-performance fiberboard. Background technique [0002] Fiberboard is a wood-based panel made by interweaving lignocellulosic fibers and utilizing its inherent adhesive properties. It is a wood-based panel made of wood fiber or other vegetable fibers, which are glued under heat and pressure after applying an adhesive. As a new type of high-grade and environmentally friendly base material, fiberboard has been widely adopted by furniture manufacturers in European and American countries, and the domestic high-end panel furniture market has also begun to use this kind of board in large areas. However, the existing fiberboard has limited its wider application due to its insufficient mechanical properties. Contents of the invention [0003] In view of the above problems, the present invention aims to provide a high-performance fiberboard. [0004] The present invention is ...
