Description

Technical Field

[0001] The utility model belongs to the technical field of wooden door production, and in particular relates to a fire-proof and flame-retardant solid wood composite door. Background Art

[0002] Driven by the demands of building safety and aesthetic design, fire-resistant and flame-retardant solid wood composite doors represent a significant innovation in the door and window industry. They incorporate a variety of advanced materials and processes to provide enhanced fire resistance and superior aesthetics. Primarily based on solid wood, these doors are combined with a variety of high-density baseboards, metal mesh, and fireproof panels to create the door body. The solid wood base provides a natural aesthetic and environmentally friendly finish. The high-density baseboard enhances the door's overall structural strength, while the metal mesh provides thermal insulation and structural support during fire. The fireproof panels are coated with a baked-on lacquer finish, offering both aesthetics and durability while also possessing excellent fire resistance and antioxidant properties. The surrounding fire-resistant frames and base effectively isolate the flame propagation path. Constructed from fire-resistant composite materials and special flame-retardant materials, these doors boast a higher fire resistance rating. Flame-retardant foam fills the door's interior, providing effective thermal and sound insulation and enhancing overall fire resistance. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that when a fire occurs, traditional doors may accelerate the spread of fire. The fire-retardant solid wood composite door effectively isolates and prevents the spread of flames by using flame-retardant materials, fire-resistant frames and bottom frames, etc., which greatly improves the fire resistance of the door and protects the building structure and personnel safety.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions: a fire-proof and flame-retardant solid wood composite door, comprising a door body, fire-resistant frames are arranged around the door body, door handle switches are arranged on both sides of the middle of the door body, the door body comprises a high-density bottom plate, metal mesh is arranged on both sides of the high-density bottom plate, fireproof boards are arranged on the outer ends of the metal mesh, and paint layers are arranged on the outer sides of the fireproof boards. The fire-resistant frames arranged around enhance the overall structure of the door, can effectively block the transfer of flames and heat, and improve the fire resistance of the door. The combination of the high-density bottom plate and the metal mesh improves the overall strength and stability of the door. At the same time, the metal mesh can play the role of heat insulation and structural reinforcement during fire prevention. The paint layer arranged on the outer side of the fireproof board is not only beautiful, but also can improve the fire resistance level and antioxidant ability of the door, and increase the service life and appearance texture of the door.

[0005] Furthermore, the fire-resistant frame includes a fire-resistant bottom frame, which is provided with fire-resistant strips. The fire-resistant bottom frame is attached to the four sides of the door body by hot pressing. The fire-resistant bottom frame is attached to the four sides of the door body by hot pressing, which effectively improves the overall fire resistance of the door. The fire-resistant bottom frame is usually made of special materials that can withstand high temperatures, such as fire-resistant composite materials or special flame-retardant materials, which can delay the spread of flames in the event of a fire. The fire-resistant strips further increase the fire resistance of the door. They are usually located on the outside of the fire-resistant bottom frame and serve as an additional barrier layer, which can effectively block the transfer of flames, heat and smoke, protecting the structure inside the door and the surrounding environment.

[0006] Furthermore, the thickness of the high-density bottom plate is greater than that of the fireproof board, and the overall size and shape are the same.

[0007] Furthermore, the fireproof board is brushed and bonded to the metal mesh and the high-density bottom plate with liquid glue. The use of liquid glue for fixed bonding can effectively fill and cover the tiny depressions and unevenness on the surface of carbon fiber and other materials, forming a uniform bonding layer and improving bonding strength and durability.

[0008] Furthermore, the first layer between the fireproof board, the metal mesh and the high-density bottom plate is covered with flame-retardant carbon fiber and fixed and bonded with liquid glue. The flame-retardant carbon fiber has high high temperature resistance and flame retardant properties, and can effectively prevent the spread of flames and combustion, thereby improving the overall fire protection level. Carbon fiber has excellent mechanical properties and can enhance the strength and rigidity of the board, making the overall structure more stable and durable. The use of flame-retardant carbon fiber and the use of liquid glue for fixing and bonding can effectively improve the fire protection performance, enhance structural stability, and have the advantages of lightweight, environmental protection and health.

[0009] Furthermore, the second layer between the fireproof board, the metal mesh and the high-density bottom plate is fully filled with flame-retardant foam. The foam filling has good fluidity and plasticity, and can well fill spaces of various complex shapes during the construction process.

[0010] Compared with the prior art, the beneficial effects of this invention are:

[0011] 1. Enhanced structural stability and durability: Through the combined design of high-density base plate, metal mesh and fireproof board, and the bonding of liquid glue and flame-retardant carbon fiber, the overall structure is more stable and durable, with excellent mechanical properties and high temperature resistance, extending the service life of the door.

[0012] 2. Flame-retardant carbon fiber has high high temperature resistance and flame retardant properties, which can effectively prevent the spread of flames and combustion, thereby improving the overall fire protection level. Carbon fiber has excellent mechanical properties, which can enhance the strength and rigidity of the board, making the overall structure more stable and durable.

[0013] 3. Combined with the design of fire-resistant frame, fire-resistant bottom frame and fire-resistant strip, it effectively blocks the transmission of flame, heat and smoke, delays the spread of fire, greatly improves the overall fire resistance of the door, and protects the structure inside the door and the surrounding environment.
