(2) And (3) cutting a plane with the width of 20mm along the tangential direction by using a planer every 90 degrees of rotation of the outer walls of the monomers 11, so that four connecting surfaces 12 are formed on each monomer 11, a plurality of monomers 11 are arranged in an array, and the outer walls of every two adjacent monomers 11 are bonded through the connecting surfaces 12 to form the hole array layer 1.
(3) The opposite surfaces of the two panels 2 are glued with adhesive to form an adhesive layer 4, the adhesive layer is respectively glued with the upper surface and the lower surface of the hole array layer 1, and the opposite surfaces of the four side plates 3 are glued with the four side surfaces of the hole array layer 1 respectively, meanwhile, the panels 2 and the side plates 3 are glued to form a cuboid, and the cuboid is heated, pressurized and solidified, and pressure is applied to the bonding surfaces in a mode of weight extrusion or pressing machine and the like, so that the bonding is firmer and denser. The adhesive in this embodiment is Pu adhesive. After the bio-based winding composite board is cured and formed, the special protective paint for the recombined board is used for spraying the surface of the composite board, so that the corrosion resistance and the water resistance are enhanced.
Through tests, the axial compression bearing of the bio-based winding composite board manufactured by the embodiment is more than or equal to 15t per square meter.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
