A-grade fireproof formaldehyde-free plate and preparation method thereof

Abstract

The invention discloses an A-grade fireproof formaldehyde-free plate which is prepared from the following raw materials in percentage by mass: 15%-25% of fibers, 10%-20% of a filler, 25%-35% of a flame retardant, 15%-25% of an adhesive and 10%-20% of amino acids. The preparation method comprises the following steps: (1) weighing the raw materials; (2) mixing the flame retardant and the adhesive toobtain a mixed material A; (3) adding the fibers, the filler, the amino acids and water, and performing stirring to obtain a mixed material B; and (4) injecting the mixed material into a mold, and performing compression molding.
