NOVELTY - A high-strength fireproof board i.e a three-layer hot-pressed composite structure, from top to bottom consisting of a fiber layer, a foamed fiber layer, and a fiber layer; The fiber layer is composed of a single or multiple fiber felt that has been impregnated with a thermosetting resin mixture solution and dried and cut. The foamed fiber layer is composed of a single or multiple fiber felts that have been impregnated with a thermosetting resin foaming mixture solution and dried and cut. USE - The high-strength fireproof board is useful in partition walls, protective panels, decorative panels, and sound insulation boards (claimed). ADVANTAGE - The high-strength fireproof plate has excellent flame retardance, wear resistance, high and low temperature resistance, sound absorption and antistatic characteristics, and self-extinguishing performance, without adding any fire retardant or other additives. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing the high-strength fireproof board comprising selecting a corresponding press tray according to the thickness of the high-strength fireproof board, laying release film, laying each layer of the high-strength fireproof board from bottom to top according to the structure, laying release film in the tray, placing it in a hot press machine, hot pressing and foaming under the conditions of temperature of 130-160℃ and pressure of 1-20 MPa for 2-60 minutes, cooling under the pressure of 1-20 MPa in a cold press machine for 10-30 minutes, and removing the release film; and (2) a wear-resistant fireproof decorative panel is obtained by one-time hot pressing, or two-time hot pressing, or adhesive composite molding of the high-strength fireproof board.
