Abstract

The invention discloses a solid wood fireproof door. The solid wood fireproof door comprises flame-retardant powder at an uppermost layer, a fireproof adhesion layer serving as a middle layer and a basic material at a lowermost layer, wherein the flame-retardant powder comprises phosphoric acid, urea, water-soluble ammonium polyphosphate and dipentaerythritol; the fireproof adhesion layer is made of fireproof silica gel; the flame-retardant powder accounts for 20-24% of the total components of the solid wood fireproof door; the fireproof adhesion layer accounts for 10-12% of the total components of the solid wood fireproof door; and the basic material accounts for 65-69% of the total components of the solid wood fireproof door. The solid wood fireproof door provided by the invention has the advantages of low possibility of deformation, adjustable color and luster and capability of showing natural aesthetic feeling of wood grains.

Description

technical field [0001] The invention relates to a solid wood fire door. Background technique [0002] As an integral part of the firewall, wooden fire doors should also be made of flame retardant materials in addition to their fire resistance limit. However, the "General Technical Conditions for Wooden Fire Doors" does not have any requirements for the facing materials of the doors. [0003] Article 3 of the "Supplementary Rules for Type Approval of Steel and Wooden Fire Door Products" stipulates that wooden fire door manufacturers must be equipped with wood flame retardant treatment equipment. However, because some manufacturers stated in the technical documents submitted by the factory certification and type inspection certification that the wood has not been treated with flame retardant, a kind of understanding has been formed, that is, when using hardwood to produce fire doors, the wood does not need to be treated with flame retardant. This formulation is extremely har...
