Problems solved by technology

However, in the door leaf of this kind of composite fireproof door, the fireproof board is set in the space inside the door leaf frame. During transportation and installation, it is easy to shake in the frame of the door leaf and collide with the frame of the door leaf. In addition, the strength of the perlite fireproof board is low, which can easily cause the perlite particles on it to fall off, scatter and accumulate in the space of the frame of the door leaf, and at the same time cause perlite The rock fireproof board is damaged and incomplete, which leads to the deterioration of the fireproof effect and heat insulation effect of the fireproof door

Embodiment 1

[0040] The preparation method of the wooden fireproof door of the present embodiment comprises the steps:

[0041] 1) Use pine blanks to prepare a wooden skeleton. The wooden skeleton is a "mesh"-shaped frame, including two longitudinal beams and four cross beams. Evenly spaced in the extension direction. The length of the wooden skeleton is 225cm and the width is 91cm.

[0042] 2) Mix and stir alumina powder, aluminum phosphate, and phosphoric acid with a mass fraction of 10% in a mass ratio of 1:1:10, then add water to dilute it by 3 times and pour it into the dipping tank, and immerse the wooden skeleton in the dipping tank for 30 minutes. Take it out, and dry it with hot air at 80°C for 2 hours to prepare a flame-retardant wooden skeleton.

[0043] 3) Take a fireproof decorative board, which is a rectangular board with a length of 230cm and a width of 95cm. The size of the fire-resistant decorative board is slightly larger than the flame-retardant wooden skeleton, so th...

[0052] The preparation method of the wooden fireproof door of the present embodiment comprises the steps:

[0053] 1) Use pine blanks to prepare a wooden skeleton. The wooden skeleton is a "mesh"-shaped frame, including two longitudinal beams and four cross beams. Evenly spaced in the extension direction. The length of the wooden skeleton is 225cm and the width is 91cm.

[0054] 2) Mix and stir alumina powder, aluminum phosphate, and phosphoric acid with a mass fraction of 5% in a mass ratio of 1:2:25, add water to dilute it by 2 times, pour it into the dipping tank, and immerse the wooden skeleton in the dipping tank for 20 minutes. Then take it out and dry it with hot air at 100°C for 15 minutes.

[0055] Stir and mix the ammonium polyphosphate with a mass ratio of 1:3 and water evenly, and then pour it into another dipping tank. Immerse the above-mentioned hot-air-dried wooden skeleton in the dipping tank for 30 minutes, then take it out, and dry it with hot air at 100°C ...

[0065] The preparation method of the wooden fireproof door of the present embodiment comprises the steps:

[0066] 1) Use pine blanks to prepare a wooden skeleton. The wooden skeleton is a "mesh"-shaped frame, including two longitudinal beams and four cross beams. Evenly spaced in the extension direction. The length of the wooden skeleton is 225cm and the width is 91cm.

[0067] 2) Mix and stir alumina powder, aluminum phosphate, and phosphoric acid with a mass fraction of 5% in a mass ratio of 1:2:15, then add water to dilute it by 3 times and pour it into the dipping tank, and immerse the wooden skeleton in the dipping tank for 10 minutes. Then take it out and dry it with hot air at 120°C for 8 minutes.

[0068] Stir and mix the ammonium polyphosphate and water with a mass ratio of 1:2, and then inject it into another dipping tank. Immerse the above-mentioned hot-air-dried wooden skeleton in the dipping tank for 20 minutes, then take it out, and dry it with hot air at 80°C...

Abstract

The invention discloses a preparation method of a wooden fireproof door and a wooden fireproof door, belonging to the technical field of fireproof doors. The preparation method of the wooden fireproof door of the present invention comprises the following steps: impregnating the wooden framework with a flame-retardant dipping solution and drying to obtain a flame-retardant wooden framework; bonding the first fire-resistant decorative board to one of the flame-retardant wooden framework side and form a filling space in the wooden skeleton, add fireproof filling materials into the filling space, and press for the first time; then bond the second fireproof decorative board on the other side of the fire-retardant wooden skeleton, and press for the second time to obtain Door panel core: bonding the outer surfaces of the first fireproof decorative board and the second fireproof decorative board of the prepared door panel core with flame-retardant medium-density fiberboard, and pressing them together. In the preparation method of the wooden fireproof door of the present invention, the fireproof filling material is filled in the filling space surrounded by the wooden skeleton and the fireproof decorative board, and then pressed, so as to avoid the fireproof filling material from loosening and falling off during later use and affecting the fireproof performance.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a method for preparing a wooden fire door and a wooden fire door. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of an ordinary door, it can prevent the spread of fire and smoke, and ensure that the speed of fire spread is reduced within a certain period of time. Make sure people have enough time to evacuate. [0003] The door leaves of the current fire doors are mostly fire doors that use perlite core board as the door core and fireproof materials as the panel. However, the fire doors directly composited with multi-layer boards have poor strength, and generally need to add wooden skeletons. [0004] The Chinese invention patent application with the application publication number CN105952347A discloses a wooden heat-insu...
