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. The A-grade fireproof formaldehyde-free plate has excellent physical properties and super-strong fireproof and waterproof properties, does not contain formaldehyde, and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of decorative materials, and more specifically relates to a class A fireproof formaldehyde-free board and a preparation method thereof. Background technique [0002] Decorative board is a product used to decorate the inner and outer walls of houses, home decoration ceilings, and wall partitions. Because of its beautiful appearance and easy installation, it is widely used. However, there are still many problems in the use of decorative panels in the decoration industries such as fire doors, floors and engineering decoration, which limits its development. [0003] Fire door industry: low-grade products, steel transfer printing is generally used, and fire-proof inorganic materials are added inside; hidden dangers of the product are obvious, internal filling materials have important quality problems such as non-environmental protection, corroded steel plates, etc., MDF or steel used on the surface does not have ...
