Problems solved by technology

[0004] The existing fire doors achieve the purpose of fire protection by filling materials such as rock wool and expanded perlite in the hollow door leaf. Due to the problems of materials and process methods, such fire doors are prone to uneven filling and gaps. or dead corners, the fire resistance is not high, and the drying process is not sufficient during processing, and it is easy to corrode or crack when used later

Embodiment 1

[0027] Embodiment 1, the existing solid wood door preparation process, comprises the following steps:

[0028] (1) Drying of wood: Put the board into the drying kiln for spray steaming and drying to obtain the rough material;

[0029] (2) Blanking: process the rough material into the specified dimensions, and ensure the consistency;

[0030] (3) Cleaning: wash off the sawdust, dust and other impurities on the surface of the blank with clean water;

[0031] (4) Hot pressing: Set the hot pressing temperature and pressure, and slowly put the solid wood door blank into the hot press machine. fill all positions;

[0032] (5) Cold pressing: first clean up the sundries on the press and put a light sheet on it, measure with a ruler to ensure that the thickness of the solid wood door blank after hot pressing is consistent, and then send it into the cold press;

[0033] (6) Edge trimming: Cut the cold-pressed solid wood door blank material, the cutting error does not exceed 0.2MM cut...

Embodiment 2

[0034] Embodiment 2, a kind of preparation technology of fire door, comprises the following steps:

[0035] (1) Drying of wood: select solid wood boards, put them into a drying kiln for spray steaming and drying, and obtain blanks. The time for spraying and steaming of the boards is 15 minutes, and the time for heating and drying is 25 days;

[0036] (2) Cutting: process the rough material into the specified shape and size, and ensure the consistency, and cut the glass fiber fireproof cloth into the same shape and size as the rough material;

[0037] (3) Cleaning: wash off the sawdust, dust and other impurities on the surface of the blank with clean water;

[0038] (4) Firing and regaining moisture: put the cleaned blanks into the kiln for firing, and leave the kiln after the temperature difference between the inside and outside of the kiln is less than 15°C, stack them neatly and perform natural moisture regaining treatment for 30 days to obtain solid wood door blanks;

Embodiment 3

[0043] Embodiment 3, a kind of preparation technology of fire door, comprises the following steps:

[0044] (1) Drying of wood: select solid wood boards, put them into a drying kiln for spray steaming and drying, and obtain blanks. The time for spray steaming of the boards is 15 minutes, and the time for heating and drying is 28 days;

[0045] (2) Cutting: process the rough material into the specified shape and size, and ensure the consistency, and cut the glass fiber fireproof cloth into the same shape and size as the rough material;

[0046] (3) Cleaning: wash off the sawdust, dust and other impurities on the surface of the blank with clean water;

[0047] (4) Firing and regaining moisture: put the cleaned blanks into the kiln for firing, and leave the kiln after the temperature difference between the inside and outside of the kiln is less than 15°C, stack them neatly and perform natural moisture regaining treatment for 30 days to obtain solid wood door blanks;

Abstract

The invention provides a preparation process of a fireproof door. The preparation process comprises the following steps of wood drying, charging, cleaning, firing, moisture regaining, hot pressing, cold pressing, edging, fine cutting and painting. Through initial drying and subsequent firing and moisture regaining of wood, the dryness of a panel is ensured, and the phenomena of corrosion and cracking of the panel after long-term use are avoided; glass fiber fireproof cloths are alternately added in the hot pressing process, the fireproof effect of the panel is achieved, the preparation methodis simple, raw materials of the panel do not need to be proportioned again, and the production efficiency is high; the surface of a fireproofing door blank is coated with a fireproof coating, and thefireproof performance is improved; and meanwhile, through strict treatment of the multiple steps, moisture in air is effectively isolated, the effects that the door panel is not easily deformed and isnot liable to crack are ensured, and the durability of the door if improved.

Description

technical field [0001] The invention relates to the field of wood production and processing, in particular to a fireproof door, in particular to a preparation process for a fireproof door. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. [0003] Drying of wood is a key process in the manufacture of solid wood doors: first of all, the drying quality of wood determines the yield of wood. Especially for precious tree species timber, it is of great significance. Second, the dry quality of ...
