Flame-retardant laminated veneer lumber wooden fireproof door and manufacturing method thereof

Abstract

The invention discloses a flame-retardant laminated veneer lumber wooden fireproof door and a manufacturing method thereof. The manufacturing method comprises the following steps of: manufacturing flame-retardant laminated veneer lumber by using low-grade fast growing wood; and manufacturing a door frame and a door leaf framework by using the flame-retardant laminated veneer lumber, wherein the door frame consists of a vertical frame and a horizontal frame through tenon combination; the door leaf framework consists of two edge horizontal keels, two edge vertical keels, a plurality of middle vertical keels and a plurality of middle horizontal keels through tenon combination; the longitudinal textures of the wood grain of the laminated veneer lumber are parallel to the length directions of the frames of the door frame and the keels of the door leaf framework, and an adhesive layer surface is vertical to the surface of the door leaf; the width of the frames of the door frame is 90 to 110mm, and the thickness is 40 to 50mm; and the width of the edge keels of the door leaf framework is 50 to 60mm, the width of the middle keels is 40 to 50mm, and the thickness of the door leaf framework is 35 to 40mm. The flame-retardant laminated veneer lumber wooden fireproof door is made of the low-grade fast growing wood, the use value of the low-grade wood is improved and natural forest resources are protected.

Description

technical field [0001] The invention belongs to the field of fire doors, and in particular relates to a wooden fire door made of fast-growing wood flame-retardant laminated veneer lumber and a method thereof. Background technique [0002] The door frame and door frame of wooden fire doors are the key components of wooden fire doors, which directly affect the fire resistance of wooden fire doors. The frame and frame of wooden fire doors have always been made of high-quality solid wood that has undergone flame-retardant treatment. However, due to the large thickness of solid wood, it is difficult to treat flame-retardant, and the penetration depth of flame retardant is shallow, usually less than 10mm. The flame retardant effect of flame retardant solid wood is poor, and the flame retardant cost is high. After the flame retardant treatment and drying, the solid wood will also be deformed. In the subsequent use process, the flame retardant solid wood needs to be cut and shaped,...
