COMPOSITE BOARD SUBSTRATE, COMPOSITE BOARD SUBSTRATE PREPARATION METHOD, AND DECORATIVE BOARD
Document Type and Number:
WIPO Patent Application WO/2022/000237
Kind Code:
A1
Abstract:
The present invention relates to a composite board substrate, a composite board substrate preparation method and a decorative board, and is intended to provide a novel substrate with a good flexibility and a high strength. The composite board substrate is prepared from polypropylene fibers, filling fibers, a flame retardant, a coupling agent and an inorganic filler by means of hot pressing, wherein the filling fibers are one or more of PET fibers, PE fibers, glass fibers, carbon fibers and wood fibers. The preparation method involves: firstly mixing the inorganic filler, the filling fibers and the coupling agent; then blending the mixed filler with the polypropylene fibers; next, paving the blended material into a strip shape, then pressing and molding same, and slicing same to obtain material sheets; subsequently laminating multiple layers of the material sheets, then hot-pressing same for 5-30 min at a temperature of 165-250°C and a pressure of 5-20 MPa, and cooling same to obtain a semi-finished substrate; and finally trimming and sanding the semi-finished substrate into a finished substrate. The substrate has the advantages of being stable in size and high in tenoning strength, and can be compounded with a melamine impregnated paper layer, an HPL layer or a PP decorative surface layer to manufacture different decorative boards.
